Description

Technical Field

[0001] This utility model relates to the field of powder machinery and equipment technology, specifically a water receiving component, a circulating water-cooled spray device, and a steel belt tablet press. Background Technology

[0002] The steel strip tablet press is one of the key pieces of equipment in the powder coating production process. It is mainly used to cool and press molten high-temperature powder coating into tablets, and then crush the tablets. The main functional parts of the steel strip tablet press include the tableting roller end, the crushing roller end, the conveying and cooling steel strip, and the circulating water-cooled spray device. The circulating water-cooled spray device uses a series of functional structures to cool the steel strip and the tablets above it by spraying water.

[0003] In existing technologies, circulating water-cooled spray devices use a water receiving tank located below the steel belt to create a reflux process that participates in the water circulation. Inevitably, some material residue and impurities are carried in the reflux water entering the receiving tank. Over time, this reflux water carrying impurities forms scale on the inner wall of the receiving tank, which is difficult to remove. Therefore, it is necessary to clean the receiving tank regularly to remove scale and foreign matter. Since the cooling spray receiving tanks of existing steel belt tablet presses are all fixed integrated designs, cleaning the tank each time requires a lot of time and effort, which is very inconvenient. Moreover, if the cleaning is not timely or thorough, it will also cause blockage of the circulation pipeline, which will have varying degrees of impact on the overall performance and lifespan of the device.

[0004] In view of the above, optimizing the water receiving components of the circulating water-cooled spray device to improve the convenience and timeliness of cleaning is a key factor in ensuring the normal operation of the device and the tablet press. Utility Model Content

[0005] The present invention aims to solve the various problems mentioned above, and thereby provides a water receiving component, a circulating water-cooled spray device, and a steel belt tablet press.

[0006] Firstly, this utility model proposes a water receiving component, which is special in that it changes the traditional one-piece structure of the water tank to a separate combined structure consisting of a water receiving trough and a water tank.

[0007] The water receiving trough is fixedly installed at an angle and has an opening at its lower position. The water tank is movably installed on the opening side of the water receiving trough in a pull-out and movable manner.

[0008] The water tank has an open top and a two-tiered design formed by the surrounding cross-sections, including a relatively low overlapping area and a relatively high open area. The relatively low overlapping area is located on the bottom surface of the water receiving trough opening side and is in a gap fit with it.

[0009] Furthermore, the width of the water tank is greater than the width of the opening side of the water receiving trough.

[0010] Furthermore, the water tank is equipped with a handle on the outside for pulling and dragging the water tank.

[0011] Furthermore, a guide rail is provided on each side of the bottom of the water tank, and the guide rails slide in contact with the surface of the bottom support.

[0012] Furthermore, a valved water outlet is provided on the outside of the water tank, through which the return water can be recirculated into the heat exchanger.

[0013] Furthermore, the water tank is equipped with a drain pipe with a valve on its outer side.

[0014] Furthermore, a visual liquid level thermometer is installed on the outside of the water tank to monitor the water temperature and liquid level inside the tank in real time.

[0015] Secondly, this utility model proposes a circulating water-cooled spray device, which is configured below the conveyor steel belt of a tablet press for spraying and cooling the steel belt and the tablets above it. It includes a water pump, a heat exchanger, and a spray pipeline. The pump inlet pipeline of the water pump is connected to the circulating water outlet of the heat exchanger, and the pump outlet pipeline of the water pump is connected to the spray pipeline configured below the steel belt. Its special feature is that it also includes a split-type combined water receiving assembly consisting of a water receiving trough and a water tank. The water receiving trough is fixedly installed at an incline and has an open side at its lower position. The water tank is movably installed on the open side of the water receiving trough in a pull-out and movable manner.

[0016] The water tank has an open top and a two-step design formed by the surrounding cross-sections, including a relatively low overlapping area and a relatively high open area. The relatively low overlapping area is located on the bottom surface of the water receiving trough opening side and is in a gap fit with it.

[0017] A valved water outlet is provided on one side of the water tank, and the return water outlet is connected to the circulating water inlet of the heat exchanger via a hose.

[0018] Furthermore, a filter is installed on the hose.

[0019] Furthermore, one side of the heat exchanger is also connected to a cold water inlet pipe and a cold water outlet pipe, through which external ice water participates in the heat exchanger's circulating heat exchange.

[0020] Thirdly, this utility model proposes a steel strip tablet press, which is special in that the steel strip tablet press has the water receiving component described above.

[0021] This utility model's water receiving component, circulating water-cooled spray device, and steel belt tablet press solve the problems of difficult cleaning, time-consuming and labor-intensive operation, and low efficiency associated with traditional integrated water tanks in tablet presses. The water tank in the receiving component is movable and pull-out, allowing for easy and convenient cleaning after being removed from the equipment. It is labor-saving, efficient, and convenient. The water receiving tank, welded from 1.5mm thick 304 stainless steel sheet, is sturdy, durable, and rust-free. The water tank is connected to the external water pipe via a quick-connect stainless steel ball valve, making it easy to assemble and disassemble. A transparent, visible liquid level and temperature gauge allows for real-time monitoring of the water level and temperature in the tank. Attached Figure Description

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] Example 1

[0028] A water receiving component for a circulating water-cooled spray device, such as Figure 1-2As shown, the system consists of a water receiving trough 1 and a water tank 2, typically positioned below the spray pipes of the tablet press. The water receiving trough 1 and water tank 2 are aligned in the same direction and angle when combined. The water receiving trough 1 receives the cooling circulating water from the upper spray pipes and guides it into the water tank 2. Therefore, the side where the water receiving trough 1 connects to the water tank 2 is the open side. The water tank 2, in operation, connects to the open side of the water receiving trough 1 to receive circulating return water. When internal cleaning of the water tank 2 is required, the water tank 2 can be separated from the equipment and the water receiving trough 1 by pulling it out, allowing for easier internal cleaning. Therefore, in this embodiment, the water tank 2 is movably installed below the opening side of the water receiving trough 1 using a pull-out and movable method. The water tank 2 has an open top and a two-tiered design formed by the cross-sections of its surrounding walls, including a relatively low overlapping area 2a and a relatively high open area 2b. The relatively low overlapping area 2a is located on the bottom surface of the opening side of the water receiving trough 1 and is in clearance fit with it. To prevent water from splashing and overflowing when flowing from the water receiving trough 1 to the water tank 2, the interface width of the overlapping area 2a of the water tank 2 should be greater than the width of the opening side of the water receiving trough 1. In this embodiment, a guide rail 21 is provided on each side of the bottom of the water tank 2. The water tank 2 can be pulled out and moved along the bottom support plane by sliding contact between the guide rails 21 and the bottom support plane. To facilitate the pulling and dragging of the water tank 2, a pair of stainless steel handles 25 are provided on the outside of the water tank 2. The water tank 2 is equipped with a valved water outlet 22, a valved drain pipe 23, and a visual liquid level thermometer 24 on its outer side. The valved water outlet 22 is used to connect to the heat exchanger through a return water pipe. The visual liquid level thermometer 24 is used to monitor the internal water temperature and liquid level of the water tank 2 in real time.

[0029] In this embodiment, the water tank 2 is welded from 1.5mm thick 304 stainless steel sheet, making it sturdy, durable, and rust-resistant. The water tank 2 is connected to an external flexible water pipe via a quick-connect stainless steel ball valve, allowing for easy assembly and disassembly. A visual level and temperature gauge 24 allows for real-time monitoring of the water level and temperature within the tank.

[0030] Example 2

[0031] A circulating water-cooled spray device, such as Figure 3As shown, a spray cooling system is configured below the conveyor belt of the steel strip tablet press for spraying and cooling the steel strip and the tablets above it. Its structure includes a spray pipe 4 configured below the steel strip, a water pump 3 for outputting cooling water to the spray pipe 4, and a heat exchanger 5 connected to the front end of the water pump 3. A water receiving tank 1 is installed below the spray pipe 4, and a water tank 2 is installed below the open side of the tail of the water receiving tank 1. The water tank 2 is installed on the bottom support 10 by a movable pull-out connection. The water tank 2 has an open top and a two-tiered design formed by its surrounding cross-sections, including a relatively low overlapping area 2a and a relatively high open area 2b. The relatively low overlapping area 2a is located on the bottom surface of the water receiving tank 1 on the opening side and is in clearance fit with it. The pump inlet pipe of the water pump 3 is connected to the circulating water outlet 9 of the heat exchanger 5, and the pump outlet pipe of the water pump 3 is connected to the spray pipe 4 located below the steel belt. A valved water outlet port 22 is provided on one side of the water tank 2, and the valved water outlet port 22 is connected to the circulating water inlet 8 of the heat exchanger 5 through a flexible hose. A filter is installed on the flexible hose. A cold water inlet pipe 7 and a cold water outlet pipe 6 are also connected to one side of the heat exchanger 5, and external chilled water participates in the circulating heat exchange of the heat exchanger 5 through this circulating pipe.

[0032] Example 3

[0033] This embodiment discloses a steel strip tablet press, including a frame 11 and a crushing roller end 12, a tableting roller end 13 and a steel strip arranged on the frame 11. Below the steel strip is a circulating water cooling spray device as described in Embodiment 2. The circulating water cooling spray device includes a water receiving component as described in Embodiment 1. The water receiving component includes a water receiving tank 1 and a water tank 2.

[0034] The water tank 2 and the water receiving tank 1 are changed from an integrated structure to a separate combination structure. When the water tank needs to be cleaned and maintained, it can be moved out of the equipment, making it easier to clean impurities and other foreign objects inside the water tank.
