Batch Chargers

VIBRATORY BATCH CHARGER HVR® (NON-OSCILLATING)

GENERAL

The HVR® batch charger is used for furnaces with lateral or front end doghouses. HORN®’s batch charger type HVR® is the most classic and popular batch charger of HORN® Glass Industries AG on the market. There are three different types of it. The most common type HVR® F is available with five different chute widths, which all have individual charging performance, according to your requirements. Invented and constructed since the founding of HORN® Glass Industries AG, the HVR® is still the most popular and reliable batch charger for your glass plant.

In order to fulfil the current regulations regarding NOx values and to save more energy when producing glass, HORN® Glass Industries AG developed the very reliable batch charger HVR® 700F-2P, as approved by HORN®’s customers. However, HORN® never stops learning and always strives to improve its products. To meet the customers’ requirements, HORN® further invented the batch charger HVR® 700S-2P.

HEAT SHIELD

The heat shield, in combination with a refractory lined doghouse hood, seals the doghouse whereby secondary air supply is minimised. The heat shield also protects the batch charger from too much heat radiation.

CHARGING SYSTEM

The batch is evenly spread on the vibrating chute with the help of the charging hopper. The end piece of the vibrating chute is made of heat resistant steel and is exchangeable in order to avoid downtime if repair work is required.
The movement of the water-cooled paddle is carried out by a lever system connected to a frequency controlled gear motor or servo drive. The paddle pushes the batch evenly from the vibrating chutes into the glass melting end and creates batch piles.

HVR® 600F-2P / HVR® 700F-2P

This type of HVR® is also fixed to a movable carriage but with a separated, non-rotating frame. This rigid construction allows better sealing of the doghouse which increases the inside temperature.

The straight heat shield is designed with reinforced insulation. There is an inspection port in the doghouse hood.

Both the HVR® 600F-2P / 700F-2P have a single vibrating chute, which is separated lengthwise in the middle through a bar and a separate pusher for each side of the chute. The end piece of the vibrating chute, which is made of heat resistant steel, is exchangeable. The movement of the two water-cooled paddles is carried out by a lever system connected to a servo drive. The paddles push the batch evenly from the vibrating chute into the doghouse and create batch piles. The speed of the paddles is inverter controlled (HVR® F). By separating the vibrating chute and with the help of two paddles it is possible to influence the batch distribution in the glass melting furnace. The stroke length and the submersion depth of the pushers can be adjusted manually.

The two water-cooled paddles can be operated in three modes: totally synchronised, synchronised but shifted at 180° or operated independently.

 

BENEFITS

  • Better sealing of the doghouse due to the elimination of the rotary motion
    • NOx emission is reduced
    • Furnace energy consumption decreases
  • Easy charging inspection due to included inspection opening within the doghouse cover
  • Fast paddle change within 20 minutes
  • Suitable for preheated batch

HVR® 600S-2P / HVR® 700S-2P

The “S” indicates the innovation in these models. HORN®’s previous batch chargers were frequency driven, which the “F” referred to, but in order to positively influence the batch charging process by more finely defined paddle controls, the gear motors were replaced by servo drives. Through the servo drives, which are centrally controlled by a two-axis control, it is now possible to define the absolute number of vertices and transition rate percentage of the set point while oscillating.

This enables a more finely adjustable rotation. A 360° rotation can now be divided in up to 18 separate segments, which respectively only need to be defined by the starting point and percentage speed.
The individual vertices can easily be adjusted by using the included 9” touch panel.

The movement of the two water-cooled paddles is carried out by a lever system connected to a frequency controlled gear motor. The paddles push the batch evenly from the vibrating chute into the doghouse and create batch piles. The speed of the paddles is servo controlled (HVR® S). By separating the vibrating chute and with the help of two paddles it is possible to influence the batch distribution in the furnace.
The stroke length and the submersion depth of the pushers can be adjusted manually.

 

BENEFITS

  • Operating with two water-cooled servo engines
  • Extremely fine adjustable
  • Easy charging inspection due to included inspection opening within the doghouse cover
  • Fast paddle change within 20 minutes
  • Optimal distribution of the batch through separated paddle control thereby achieving better melting of the batch
  • Reduction of emissions in terms of NOx and dust
  • Suitable for preheated batch
  • Better sealing of the doghouse through the elimination of the rotary motion
