(54) INSTALLATION FOR GLAZING OF CERAMIC

one

The invention relates to installations for the glazing of ceramic products, mainly flat, and may be used in the construction materials industry, in particular in the production of glazed ceramic tiles. .

The installation for glazing of facade ceramic tiles is known, containing JQ fixing devices for feeding glaze slurry and compressed air, nozzles fixed by means of a rocker arm on a hollow vertical shaft which is kinematically connected to the drive, rotation 1.

The closest technical solution to the invention is the installation of a DGP glazing of ceramic products containing a frame in which. Is mounted a vertical hollow shaft with a carrier mounted on it with nozzles, kinematically connected to a drive shaft, glaze slurry and compressed air nozzles to 2J.

The purpose of the invention is to reduce the loss of the glaze slurry and compressed air by eliminating their consumption in the non-operating nozzle.

PRODUCTS

This is achieved by the fact that in an apparatus for glazing ceramic products containing a frame in which a vertical hollow shaft is mounted with a carrier with nozzles fixed on it, kinematically connected to the drive shaft, devices for feeding the glaze slurry and compressed air to the nozzles and crane gates, the body of crane gates are fixed on the carrier, the central wheel is rigidly fixed on the frame, and the gate valve of each gate is equipped with a satellite, and the satellite of one crane gate is located on one side meshes with the central wheel, while the other side - with a satellite of another crane gate and gate valves are made SCWO-znye longitudinal openings cooperating with the housing bore.

FIG. 1 shows the installation described, FIG. 2 - section A-A of FIG. one; in fig. 3 - section bb FIG. 1 in FIG. 4 - section bb FIG; 3; in fig. 5 - air distributor.

Claims (2)

The installation contains a device; for feeding glaze Su: ps-.nzni to vidg; a container 1 connected to a vertical hollow shaft i mounted on a frame (not shown in the figures), which, together with the supporting bearings 3, is located in the housing 4. The cavity of the shaft 2 communicates with the nozzle 5 with pipes b and 7, in which the valve 8 is installed; The compressed air supply system consists of an air distributor 9, which is connected to the nozzle 5 via pipelines 10 and 11 via a valve gate 12. Gear 13 13 is located on All 2, which meshes with gear 14 located on shaft 15, which rests from the sub-carriers 16. The common body 17 of the crane gates 8 and 12 are connected by a key 18 to the VS 2. The carrier 17 is fixed to the body 17 with a nozzle 5. The crane locks a and 12 connect identical parts. The shaft 20, located in the housing 21, is connected by means of a pin 22 to a shut-off valve 23, in which through longitudinal through holes are made along an arc cXp corresponding to the rotation of the nozzle in the working area. The shut-off valve, with its surface, is pressed by the spring 24 through the nut 25 and the shaft 20 to the cover 26, which is installed in the housing 17 and sealed by a seal 27. The second bearing surface of the spring 24 abuts against the substage 28. The shaft 20 is sealed in the housing 17 by a seal 29 and a pressure cap 30. A supply nipple 3 and a discharge nipple 32 are attached to the crane gate. Gears 33 and 34 are located on the shafts of the crane gates 8 and 12, the inlet I is in engagement with each other and connected with the gear 35 of the air distributor 9, containing supplying pas tubes 36. The inner race 37 of the air-distributor divider 9 with the socket 38 is connected with the hollow shaft 2 by a key 39. The bearings 40 serve as a support for: the shaft 37. The inner cavity is sealed by both 37 with a seal 41. gear 35. The number of teeth gear 33-35 alike. The installation works as follows. Glasurn suspension from the tank 1 through the hollow shaft 2, the pipe 6 and the fitting 31 enters the cavity of the body 17 of the crane valve 8, from it through the fitting 32 through the pipe 7 into the nozzle 5. Compressed air from the supplying patrus 36 through the cavity of the casing 37, the pipe 38 and the pipe 10 enters through the nozzle 31 into the cavity of the casing of the gate valve 12, from it through the nozzle 32 through the pipe 11 into the nozzle 5. When the drive shaft 15 rotates, the hollow shaft 2 with the carrier 19 and the nozzle 5, and the gear 34, rolling the gear 35, turns the shut-off valve 23 of the crane shutter 12 relative to the housing 17 with an angular velocity equal to the angular speed of rotation of the carrier relative to the flow of products, while the shut-off valve opens and closes e housing bore depending on the position of the nozzle relative to the flow, ie. e. the valve is exposed relative to the housing so that when the nozzle in the working zone of the air fed to the nozzle and otsekals from it, when the latter comes out of the working area. The shut-off valve installed in the bolt 8, when the gear 33 is driven through the gear 35, through the gear 34 rotates at the same angular speed as the previous one, but in the opposite direction, opening and closing the glazing suspension line to the nozzle depending on its position relative to the flow of products . The invention The installation for glazing of ceramic products, mainly flat, containing a frame in which a vertical hollow shaft is mounted with a carrier mounted on it with nozzles, kinematically connected with a drive shaft, devices for providing an glaze suspension and compressed air to the nozzles, and crane gates, characterized by By the fact that, in order to reduce the loss of the glaze suspension and compressed air by eliminating their consumption in the non-working area of the nozzle, the body of the crane gates are fixed on the carrier, on the bed the central wheel is rigidly fixed, and the shut-off valve of each gate is equipped with a satellite, with the satellite of one crane gate on one side meshes with the central wheel, and on the other hand with the satellite of the other crane gate, and through the gate valves there are through through longitudinal holes interacting with a housing bore.
