Description

Technical Field

[0001] This utility model relates to the field of cooling technology, and in particular to an energy-saving cooling system for plastic powder production. Background Technology

[0002] Cooling is required for both the grinding line and the tablet press during the powder production process. Currently, each grinding line and tablet press is equipped with a cooling system, but the utilization rate of these systems is low, leading to increased energy consumption and higher production costs. Furthermore, the two cooling systems occupy a significant amount of factory space. Utility Model Content

[0003] The purpose of this invention is to provide an energy-saving cooling system for plastic powder production. By integrating the grinding line and the tablet press into the same cooling line, the water used to cool the grinding line can be used to cool the tablet press again, which can effectively reduce energy consumption and reduce the footprint of the cooling system.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] An energy-saving cooling system for plastic powder production includes a chiller, multiple grinding lines, and multiple tablet presses; the grinding lines are located upstream of the multiple tablet presses.

[0006] The chiller includes an external insulated water tank, which is connected to an outlet pipe A and an inlet pipe A;

[0007] Each grinding line is connected to an inlet pipe B and an outlet pipe B, and each tablet press is connected to an inlet pipe C and an outlet pipe C; multiple inlet pipes B are connected to intermediate pipe A, multiple outlet pipes B and multiple inlet pipes C are connected to intermediate pipe B, and multiple outlet pipes C are connected to intermediate pipe C; intermediate pipe A is connected to the outlet pipe via water pump A, and intermediate pipe C is connected to inlet pipe A.

[0008] The chiller cools the first cooling water flowing through the insulated water tank. The water cooled by the insulated water tank enters the water pump A through the outlet pipe A. After being pressurized by the water pump A, it is sent to the intermediate pipe A. The first cooling water in the intermediate pipe A is divided into multiple streams and enters the grinding line through the inlet pipe B to cool the grinding line. After passing through the grinding line, the first cooling water flows back into the intermediate pipe B through the outlet pipe B. Then, the first cooling water flows downward through the intermediate pipe B and is divided into multiple streams and enters the tablet press through the inlet pipe C to cool the tablet press. The first cooling water after cooling the tablet press flows out through the outlet pipe C and flows back into the intermediate pipe C. The first cooling water in the intermediate pipe C flows back into the insulated water tank through the inlet pipe A, thus completing the cooling of the grinding line and the tablet press in one operation.

[0009] The cooling temperature of the grinding line is 7-10℃, and the cooling water temperature of the tablet press is 15-20℃. Therefore, cooling the grinding line first will raise the temperature of the water, but this will not affect the cooling of the tablet press. This allows a single cooling system to simultaneously cool both the grinding line and the tablet press, improving the practicality of the cooling system and reducing cooling costs and the space occupied by the cooling equipment.

[0010] The present invention is further configured such that: the chiller is connected to an inlet pipe D and an outlet pipe D, the inlet pipe D and the outlet pipe D are connected to a cooling tower, and a water pump B is provided at the end of the inlet pipe D near the cooling tower.

[0011] The second cooling water, after cooling the condenser of the chiller, flows out through the outlet pipe D to the cooling tower. The second cooling water, after being cooled by the cooling tower, enters the inlet pipe D, and after being pressurized by the water pump B, it is sent back into the chiller to cool the condenser, thus forming a cycle. The evaporator of the chiller is essentially located inside the insulated water tank.

[0012] The present invention is further configured such that a second valve is provided on each of the inlet pipe B and the outlet pipe B.

[0013] A fourth valve is provided on both the inlet pipe C and the outlet pipe C.

[0014] With the above technical solution, if the second valve on the inlet pipe B and the outlet pipe B is closed, the tablet press can be cooled separately; if the fourth valve on the inlet pipe C and the outlet pipe C is closed, the grinding line can be cooled separately; thus meeting the needs of different working conditions.

[0015] The present invention is further configured such that: one end of the intermediate pipe B away from the grinding line is connected to a bypass pipe A, and the other end of the bypass pipe A is connected to the water inlet pipe D;

[0016] The intermediate pipe C is connected to a bypass pipe B at one end away from the inlet pipe A, and the other end of the bypass pipe B is connected to the outlet pipe D; a fifth valve is provided on both the bypass pipe A and the bypass pipe B.

[0017] A third valve is provided on both the inlet pipe D and the outlet pipe D;

[0018] Each of the outlet pipe A and the inlet pipe A is equipped with a first valve.

[0019] If only cooling of the tablet press is required in winter, close the second valves on inlet pipe B and outlet pipe B, close the first valves on outlet pipe A and inlet pipe A, close the third valves on inlet pipe D and outlet pipe D, and open the fifth valve on bypass pipe A and bypass pipe B. Since the natural water temperature is low in winter, the water flowing out of the cooling tower enters the bypass pipe A through the inlet pipe, and then enters the tablet press through the intermediate pipe B and inlet pipe C to cool the tablet press. The cooled water flows out through outlet pipe C and merges into the intermediate pipe C. The water in the intermediate pipe C flows back to outlet pipe D through bypass pipe B. The water in outlet pipe D enters the cooling tower for cooling, thus forming a small cooling water cycle that can cool the tablet press independently.

[0020] The present invention is further configured such that a water filter is provided on the upstream side of water pump A and the upstream side of water pump B.

[0021] A water filter can be used to filter the circulating cooling water, reducing damage to the water pump and the components being cooled.

[0022] The outstanding effect of this utility model is:

[0023] Compared with existing technologies, by integrating the grinding line and the tablet press into the same cooling line, the water that cools the grinding line first can be used to cool the tablet press again, which can effectively reduce energy consumption and reduce the footprint of the cooling system.

[0024] The grinding line or tablet press can also be cooled separately by closing the relevant valves;

[0025] The inlet and outlet pipes of the cooling tower are connected to the bypass pipe, which allows the tablet press to be cooled independently without turning on the chiller in winter when the water temperature is low. Attached Figure Description

[0032] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0033] The following is for reference Figure 1 The present invention will be described as follows:

[0034] An energy-saving cooling system for plastic powder production includes a chiller 10, multiple grinding lines 20, and multiple tablet presses 30; the grinding lines 20 are located upstream of the multiple tablet presses 30.

[0035] The chiller 10 includes an external insulated water tank 101, which is connected to an outlet pipe A102 and an inlet pipe A103.

[0036] Each grinding line 20 is connected to a water inlet pipe B201 and a water outlet pipe B202, and each tablet press 30 is connected to a water inlet pipe C301 and a water outlet pipe C302; multiple water inlet pipes B201 are connected to an intermediate pipe A40, multiple water outlet pipes B202 and multiple water inlet pipes C301 are all connected to an intermediate pipe B41, and multiple water outlet pipes C302 are connected to an intermediate pipe C42; the intermediate pipe A40 is connected to the water outlet pipe 102 through a water pump A43, and the intermediate pipe C42 is connected to the water inlet pipe A103.

[0037] The chiller cools the first cooling water flowing through the insulated water tank. The water cooled by the insulated water tank enters the water pump A through the outlet pipe A. After being pressurized by the water pump A, it is sent to the intermediate pipe A. The first cooling water in the intermediate pipe A is divided into multiple streams and enters the grinding line through the inlet pipe B to cool the grinding line. After passing through the grinding line, the first cooling water flows back into the intermediate pipe B through the outlet pipe B. Then, the first cooling water flows downward through the intermediate pipe B and is divided into multiple streams and enters the tablet press through the inlet pipe C to cool the tablet press. The first cooling water after cooling the tablet press flows out through the outlet pipe C and flows back into the intermediate pipe C. The first cooling water in the intermediate pipe C flows back into the insulated water tank through the inlet pipe A, thus completing the cooling of the grinding line and the tablet press in one operation.

[0038] The cooling temperature of the grinding line is 7-10℃, and the cooling water temperature of the tablet press is 15-20℃. Therefore, cooling the grinding line first will raise the temperature of the water, but this will not affect the cooling of the tablet press. This allows a single cooling system to simultaneously cool both the grinding line and the tablet press, improving the practicality of the cooling system and reducing cooling costs and the space occupied by the cooling equipment.

[0039] The chiller 10 is connected to an inlet pipe D50 and an outlet pipe D51. The inlet pipe D50 and the outlet pipe D51 are connected to a cooling tower 52. A water pump B53 is provided at the end of the inlet pipe D50 near the cooling tower 52.

[0040] The second cooling water, after cooling the condenser of the chiller, flows out through the outlet pipe D51 to the cooling tower 52. The second cooling water, after being cooled by the cooling tower, enters the inlet pipe D50 and, after being pressurized by the water pump B53, is sent back into the chiller to cool the condenser, thus forming a cycle. The evaporator of the chiller is essentially located inside the insulated water tank.

[0041] A second valve 203 is provided on each of the water inlet pipe B201 and the water outlet pipe B202.

[0042] A fourth valve 303 is provided on each of the water inlet pipe C301 and the water outlet pipe C302.

[0043] If the second valve 203 on the inlet pipe B201 and the outlet pipe B202 is closed, the tablet press can be cooled separately; if the fourth valve 303 on the inlet pipe C301 and the outlet pipe C302 is closed, the grinding line can be cooled separately; this can meet the needs of different working conditions.

[0044] The intermediate pipe B41 is connected to a bypass pipe A44 at one end away from the grinding line 20, and the other end of the bypass pipe A44 is connected to the water inlet pipe D50.

[0045] The intermediate pipe C42 is connected to a bypass pipe B45 at one end away from the inlet pipe A103, and the other end of the bypass pipe B45 is connected to the outlet pipe D51; a fifth valve 46 is provided on both the bypass pipe A44 and the bypass pipe B45.

[0046] A third valve 54 is provided on each of the water inlet pipe D50 and the water outlet pipe D51;

[0047] Each of the outlet pipe A102 and the inlet pipe A103 is equipped with a first valve 104.

[0048] If only cooling of the tablet press is required in winter, close the second valve 203 of the inlet pipe B201 and the outlet pipe B202, close the first valve 104 on the outlet pipe A102 and the inlet pipe A103, close the third valve 54 on the inlet pipe D50 and the outlet pipe D51, and open the fifth valve 46 on the bypass pipe A44 and the bypass pipe B45. Since the natural water temperature is low in winter, the water flowing out of the cooling tower enters the bypass pipe A through the inlet pipe, and then enters the tablet press through the intermediate pipe B and the inlet pipe C301 to cool the tablet press. The cooled water flows out through the outlet pipe C302 and flows into the intermediate pipe C42. The water in the intermediate pipe C flows back to the outlet pipe D51 through the bypass pipe B45. The water in the outlet pipe D enters the cooling tower for cooling, thus forming a small cooling water cycle that can cool the tablet press independently.

[0049] A water filter 55 is provided on the upstream side of water pump A43 and water pump B53 respectively.

[0050] A water filter can be used to filter the circulating cooling water, reducing damage to the water pump and the components being cooled.

[0051] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
