Description

Technical Field

[0001] The utility model relates to a circulating water cooling system and a steel belt tablet press, belonging to the technical field of powder processing equipment. Background Art

[0002] The steel belt tablet press is a key piece of equipment in the powder coating production process. It is primarily used to cool and compress molten, high-temperature powder coating into flakes, which are then crushed. The main functional components of the steel belt tablet press include the tableting roller, crushing roller, conveyor cooling steel belt, and a circulating water cooling system, the latter of which is used to cool the flakes on the steel belt.

[0003] Currently, the circulating water cooling system for steel strip tablet presses is generally installed in a fixed position on the equipment. It is usually fixed inside the frame near the tableting roller end or hung externally on the equipment frame. It cannot be moved and cannot be interchanged with other equipment water tanks, heat exchangers, filters, etc. The problem caused by this installation method is that personnel must enter the equipment for regular cleaning, maintenance and repair. Due to the extremely compact interior and limited space, cleaning and maintenance are inconvenient, time-consuming and labor-intensive, and seriously affect production efficiency.

[0004] In addition, the water pressure in the water channel of the current steel belt tablet press is too low. When the filter needs to be cleaned, the machine must be shut down and cannot be cleaned at any time, which reduces production efficiency. Product waste will occur during the shutdown and restart process. Utility Model Content

[0005] The present invention aims to solve the above-mentioned problems and further provides a circulating water cooling system and a steel belt tablet press. The circulating water cooling system and the steel belt tablet press adopt a detachable split structure, which greatly simplifies the operation difficulty of cleaning and maintenance, saves time and labor, and is convenient and efficient.

[0006] In order to solve the above problems, the technical solution adopted by the present utility model is:

[0007] The circulating water cooling system is unique in that it is detachably connected to the steel belt tablet press in an integrated independent structure. Its structure includes a frame with rollers at the bottom, and a water tank, water pump, filter assembly and heat exchanger arranged on the frame and connected by pipes.

[0008] The water tank has a return water tank, which is connected to the return water pipe of the spray pipeline below the steel belt;

[0009] The water tank has a water filter chamber, which is connected to the water pump through a pumping pipeline;

[0010] The water pump is installed between the water tank and the filter assembly to pump water in the water tank into the filter assembly for filtration. The filter assembly is connected to the heat exchanger through a pipeline.

[0011] Furthermore, a filter partition is provided in the water tank, and the water tank is separated by the filter partition to form a return water tank and a filter water tank.

[0012] Furthermore, the filter assembly includes a filter water inlet pipe, two juxtaposed filter branches and a filter water outlet pipe, each of the two filter branches is provided with a filter, and the front and rear ends of the filter are respectively provided with a movable ball valve.

[0013] Furthermore, one end of the heat exchanger is connected to the filtered water outlet pipe, and the other end is connected to the spray pipeline below the steel belt through a cooling water delivery pipeline.

[0014] Furthermore, the heat exchanger has an ice water inlet and an ice water outlet communicating with the ice water.

[0015] Furthermore, a ball valve is provided on the pipeline between the water filter bin and the water pump.

[0016] Furthermore, a tee is arranged on the pipeline between the water pump and the filter assembly, one end of the tee is connected to the pump outlet pipeline of the water pump, the other end is connected to the filter inlet pipe of the heat exchanger, and the third end is connected to the pump inlet pipeline of the water pump via an overflow pipeline and a valve.

[0017] The steel belt tablet press includes a tableting roller end, a crushing roller end, and a conveying cooling steel belt located between the tableting roller end and the crushing roller end. The special feature of the steel belt tablet press is that it also includes a circulating water cooling system that is detachably connected to the steel belt tablet press in an integral independent structure.

[0018] The utility model discloses a circulating water cooling system, which is part of a steel belt tablet press. The traditional fixed installation structure is replaced with an independent split design. When in operation, the circulating water cooling system is arranged on the ground within the angle formed by the crushing end support legs of the steel belt tablet press and the ground. The cooling water is sprayed on the back of the steel belt through the water supply to the spray pipe, thereby cooling the material on the steel belt tablet press. The cooling water then flows back to the water tank through the return pipe. The circulating water cooling system of the utility model can be moved out of the water tank in parallel without disassembling the main body of the steel belt tablet press. The bottom roller design can be moved at will, which improves the convenience and efficiency of the water tank cleaning and maintenance process.

[0019] As another improvement, the filter assembly of the present invention uses two filters installed in parallel, which can operate separately. Normally, one filter is open and the other is closed to ensure the normal operation of the equipment and normal production. When the water pressure of the circulating water cooling system of the steel belt tablet press is too low, it means that there are too many impurities in the filter and it needs to be cleaned. At this time, the ball valves at the front and rear ends of one filter can be closed, and the ball valves at the front and rear ends of the other filter can be opened. Then, the outer cylinder of the filter can be manually removed and the filter element can be replaced. This can achieve the goal of switching the operating pipeline without stopping the machine, and the cleaning work can be done at the same time, which can greatly improve production efficiency.
