BATCH CHARGER MODELS HVR®

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,

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.

CO L D TOP BATCH CHARGER HVFE

The cold top batch charger is used for electrically heated furnaces. The batch charger is manufactured in a solid welded and screwed construction and runs in two axes – x and z – through two carriages. Each carriage is driven by a frequency controlled gear motor. In this way, the vibrating feeder moves just above the glass surface in the furnace and feeds parallel batch layers on top of the surface. Initiators monitor the positions of both axes of the charging machine. The charging machine is equipped with a batch hopper and level detectors. When the hopper is nearly empty, the charger moves automatically to a filling and docking station to be refilled.

F LOAT B ATCH CHARGER HFB

One of the latest batch chargers in HORN®’s product range is the float batch charger HFB, which is used to continuously feed the float glass furnace. The chargers are installed at the front part of the melting end at the doghouse across its full width. The operating element of the charger is driven by an electric motor. All batch chargers in the charging system are constructed identically. The float batch charger consists of a main frame and a mobile sub frame, which can be moved by means of four heavy duty castors. The machine is fixed to the position in front of the wall using floor mounts. The batch is supplied on the operating element from the special hopper located at the top of the furnace. The day silo, which is situated in front of the melting tank, feeds the batch into the funnel of the charging machine. The continuous lifting motion of the charging chute loads the batch into the doghouse area of the furnace. A driving unit powers the lifting motion.

Batch and cullet chargers are controlled in such a way that the glass level in the melting tank measured by the level control system is constant. The gap between the melting end and the chargers is covered over the total width of the doghouse and is executed in two parts. The charging quantity of the individual machine can be adjusted via a layer height adjustment.
