Technical Field
The utility model discloses be applied to the centrifugal casting field, concretely relates to scribble paint can when centrifugal casting coating spraying.
Background
Centrifugal casting has many processes, of which the hot mold method is a more common production process, especially in the production of centrifugal cast steel pipes. Heating the metal pipe die to a certain temperature, spraying a refractory coating in the pipe die, drying the coating, and pouring molten iron or molten steel. Cooling to form the cast iron pipe or the cast steel pipe.
Since cast steel pipes are required to have a high degree of refractoriness as a coating material due to the high melting point and high casting temperature of cast steel, zircon powder having a melting point of 2400 ℃ or higher is generally used as an aggregate, but the specific gravity of zircon powder is 4.6g/cm3 or so. The conventional suspending agents such as bentonite, attapulgite, CMC and the like cannot achieve the long-time suspension of the zircon powder. After the coating is kept stand for a certain time, zircon powder is precipitated, and the zircon powder must be stirred uniformly again before use. Especially for pressurized spraying, coating remains in the spray pipe, which risks clogging of the spray pipe.

The utility model provides a technical problem be: the coating tank is specially designed for pressure spraying of zircon powder coating, so that the coating in the coating tank does not precipitate, and the spraying pipe is not blocked.
The utility model adopts the technical proposal that: the coating tank is hermetically connected with the tank body through a tank cover, and the tank cover is provided with a light inlet, a compressed air inlet, a pressure gauge, a pressure relief port, a coating inlet and a standby port; the compressed air inlet, the pressure gauge, the pressure relief port, the coating inlet and the standby port are hermetically connected with the tank cover through valves, and the components are arranged on the periphery of the tank cover for convenient operation; a filter screen is arranged in the coating inlet, and large particles in the coating can be filtered. The bottom of the tank body is spherical or ellipsoidal, a drain outlet is arranged at the lowest point of the tank body, and a coating stirring device is arranged on one side of the drain outlet and is preferably arranged in an inclined mode perpendicular to the spherical surface or the ellipsoidal surface of the tank bottom. An observation hole is arranged at the upper part of the tank body, and the observation hole and the light inlet hole are together used for observing the state of the coating in the tank. The bottom of the tank body is connected with a spraying pipe through a spraying pipe valve, and the spraying pipe is connected with a water inlet pipe with a water inlet valve, so that the spraying pipe and the tank body can be cleaned.
The utility model has the advantages that: the problems of precipitation of the zircon powder coating and blockage of a spraying pipe are solved, pressure spraying of the zircon powder coating is realized, the coating state can be observed in real time, and misoperation is avoided.

FIG. 1 is a schematic structural view of the present invention;
wherein: 1-tank cover, 2-compressed air inlet, 3-standby port, 4-pressure gauge, 5-pressure relief port, 6-coating inlet, 7-filter screen, 8-light inlet, 9-tank body, 10-stirring device, 11-sewage outlet, 12-water inlet pipe, 13-spraying pipe and 14-observation hole.
Detailed Description
The utility model discloses the coating can is as shown in figure 1, and for the requirement that adapts to the pressure spraying, cover 1 and jar body 9 sealing connection, all pipeline of being connected with cover 1 or jar body 9 all install valve control.
A compressed air inlet 2, a pressure gauge 4, a pressure relief port 5, a coating inlet 6, a light inlet 8 and a standby port 3 are designed and installed on the tank cover 1. The light inlet hole 8 is sealed with the tank cover 1 by adopting a transparent material and can bear the pressure of compressed air. The rest compressed air inlets 2, the pressure gauge 4, the pressure relief port 5, the coating inlet 6 and the standby port 3 are all connected with the tank cover 1 by valves. Under normal conditions, the compressed air inlet valve is adjusted to be opened and closed according to the pressure requirement in the tank. The pressure gauge valve is normally open and is closed only when the pressure gauge is maintained or replaced. The valve of the pressure relief opening is normally closed, and the valve is opened only when the coating is added or the tank body is cleaned or maintained and pressure relief is needed. The paint inlet valve is normally closed and is opened only when paint is added. The spare port valve is normally closed. The above components are typically mounted on the periphery of the can lid 1 for ease of handling and viewing. Install filter screen 7 in the coating import 6, the coating filters the back through filter screen 7, can prevent that large granule material from blockking up the pipeline.
The bottom of the tank body 9 is spherical or ellipsoidal, a drain outlet 11 is arranged at the lowest point under the tank body, and under the normal condition, a valve of the drain outlet is normally closed and is opened only when the tank body is cleaned. A coating stirring device 10 is obliquely arranged beside the sewage discharge port 11, and can keep the zircon powder coating in a stirring state without generating precipitation. The stirring device 10 can be vertically installed or obliquely installed, and an oblique installation mode perpendicular to the spherical surface of the tank bottom is optimally adopted, so that the uniform stirring of the coating is facilitated.
An observation hole 14 is installed at the upper part of the can body 9, the structure and material of which are basically consistent with those of the light inlet hole 8, and the observation hole is used together with the light inlet hole 8 to observe the level of the coating liquid in the can body and whether the coating is in a stirring state.
The bottom of the tank body 9 is connected with a spray pipe 13 through a spray pipe valve, and the spray pipe 13 is connected with a water inlet pipe 12 with a water inlet valve. During spraying, open the spray tube valve, carry out the spraying operation of zircon powder coating, after the spraying is accomplished, close the spray tube valve, open inlet valve simultaneously, water washing spray tube 13 avoids zircon powder to produce the sediment in spray tube 13, blocks up the spray tube, closes inlet valve after having washed. When the tank body needs to be cleaned, the water inlet valve is opened, the valve of the spraying pipe is opened, water enters the tank body at the moment, the tank body is cleaned under the action of the stirring device 10, and then the water is discharged from the sewage discharge port 11.
The utility model discloses when the coating tank used, from the reinforced beginning of zircon powder coating, agitating unit 10 was in operating condition always, kept coating not to deposit. The spherical or ellipsoidal tank bottom can avoid stirring dead angles. The sealing state is favorable for maintaining pressure, and pressure spraying is realized.
When the compressed air inlet 2, the pressure relief port 5 or the coating inlet 6 cannot work normally, the spare port 3 can be adopted for production. In order to reduce the air leakage probability of the tank cover 1, the standby port 3 can be removed, the pressure relief port 5 is used as a standby, and the paint inlet 6 can also be used as a pressure relief port.
The utility model provides a zircon powder coating deposit and spraying pipe jam problem, realized the spraying of having pressed of zircon powder coating, but error in operation is avoided to real-time observation coating state. This coating tank simple structure, convenient operation.
