Description

Technical Field

[0001] The utility model belongs to the field of cooling equipment, in particular to a cooling circulation device for centralized water supply of dock pumps. Background Art

[0002] In the daily operation of chemical terminals, a large number of pumping equipment are needed for pumping or discharging liquids. When pumping large-capacity material storage tanks or tank trucks, the pumps need to run for a long time, so the cooling of the pumps is particularly important.

[0003] Normally, one water tank corresponds to one pump for cooling and supplying liquid. The size of the water tank is limited. The water in the water tank absorbs the heat generated by the pump and heats up quickly. The cooling effect decreases when the temperature rises. As the number of pumps increases, a large number of water tanks and connecting pipes need to be installed in the pump area. The site pipelines are complicated, and daily maintenance and inspection by the staff are difficult and easy to miss. Therefore, it is necessary to provide a cooling liquid with a lower and more stable supply temperature for the centralized water supply cooling circulation device of the dock pump. Utility Model Content

[0004] The utility model aims to provide a centralized water supply cooling circulation device for dock pumps, so as to solve the technical problems that usually one water tank corresponds to one pump for cooling and supplying liquid, the size of the water tank is limited, the water in the water tank absorbs the heat generated by the pump and heats up quickly, and the cooling effect decreases after the temperature rises. Moreover, when the number of pumps increases, a large number of water tanks and connecting pipes need to be installed in the pump area, the site pipelines are complicated, and the daily maintenance and inspection by the staff are difficult and easy to miss.

[0005] To achieve the above purpose, the specific technical solution of the utility model is as follows:

[0006] A centralized water supply cooling circulation device for dock pumps, comprising: a water supply tank: having a tank body for storing coolant; a submersible pump: arranged in the tank body and immersed in the coolant in the tank body; a main water supply pipe: one end of which is connected to the water outlet of the submersible pump and the other end is sealed; a return pipe: one end is inserted into the tank body as a drainage end and the other end is sealed, and has a cooling structure for reducing the temperature of the coolant in the return pipe; a working pump: having a water cooling part, the water cooling part having a cooling inlet and a cooling outlet, the cooling inlet is connected to the main water supply pipe, and the cooling outlet is connected to the return pipe. Through such a design, the water supply tank centrally supplies coolant to the working pump, simplifies the pipeline design of the pump area and facilitates maintenance by the staff, the water supply tank has a large capacity, and the coolant stored in the water supply tank increases the heat exchange area with the outside, keeping the coolant at a suitable low temperature for a long time.

[0007] Furthermore, the water supply tank is provided with a cover plate, and a flip handle is fixedly provided on one side of the cover plate away from the tank body. Through such a design, the cover plate can prevent debris such as soil and rocks from entering the water supply tank and blocking the pipeline.

[0008] Furthermore, the inner wall of the tank body is provided with a first slot, the first slot is removable to insert a coarse filter plate, the coarse filter plate separates the submersible pump from the drainage end of the return pipe, and the coarse filter plate is densely covered with filter holes. Through such a design, the coarse filter plate can preliminarily filter the coolant to prevent the submersible pump from being blocked by dirt.

[0009] Furthermore, the inner wall of the tank body is provided with a second slot, and the second slot can be removably inserted into the water baffle. With such a design, when the submersible pump needs to be repaired, the water baffle is inserted to drain the coolant on one side of the submersible pump, and the staff can directly enter the water supply tank for maintenance without lifting out the submersible pump.

[0010] Furthermore, the main water supply pipe is provided with a pressure sensor, the pressure sensor is connected to the submersible pump signal, and the pressure sensor is configured to detect the water pressure in the main water supply pipe. Through such a design, by detecting the water pressure in the main water supply pipe, it is determined whether there is sufficient water in the main water supply pipe to supply the working pump for cooling. When the pressure sensor detects that the water pressure in the main water supply pipe is lower than a predetermined value, the pressure sensor controls the submersible pump to open and pump water from the main water supply pipe.

[0011] Furthermore, the main water supply pipe is also provided with a filter. Through such a design, the filter performs fine filtering on the coolant in the main water supply pipe, thereby preventing impurities in the coolant from clogging the water cooling part of the working pump.

[0012] Furthermore, the cooling structure is buried in the soil layer 1m to 3m below the ground surface. The cooling structure includes a shunt inlet pipe, a shunt pipe and a shunt outlet pipe along the flow direction of the coolant. The shunt pipes are provided in multiple numbers, and the shunt pipes are connected between the shunt inlet pipe and the shunt outlet pipe. With such a design, the cooling structure is buried in the soil, and the temperature of the deep soil is relatively low, which can exchange heat with the coolant in the cooling structure, and quickly reduce the temperature of the coolant in the cooling structure. The design of the shunt pipe increases the heat exchange area of ​​the coolant and improves the heat exchange efficiency.

[0013] Furthermore, the cooling inlet of the water cooling unit is arranged on the side close to the ground, and the cooling outlet is arranged on the top of the water cooling unit. Through such a design, the cooling liquid enters from the bottom and exits from the top, and the cooling liquid is fully utilized for cooling.

[0014] Furthermore, the diameter of the main water supply pipe is larger than that of the return pipe.

[0015] Further, the cooling inlet is provided with a solenoid valve. Through such a design, when the working pump starts to work, the solenoid valve opens, and the coolant in the main water supply pipe can enter the water cooling part.

[0016] The beneficial effects of the utility model are as follows: the water supply pool centrally supplies coolant to the working pump, which simplifies the pipeline design of the pump area and is convenient for maintenance by staff; the water supply pool has a large capacity, and the coolant stored in the water supply pool increases the heat exchange area with the outside, keeping the coolant at a suitable low temperature for a long time.

[0026] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0027] like Figures 1 to 8 shown.

[0028] Example 1

[0029] A centralized water supply cooling circulation device for dock pumps, comprising: a water supply tank: having a tank body 1 for storing coolant; a submersible pump 2: arranged in the tank body 1 and immersed in the coolant in the tank body 1; a main water supply pipe 3: one end of which is connected to the water outlet of the submersible pump 2 and the other end is sealed; a return pipe 4: one end of which is inserted into the tank body 1 as a drainage end 5 and the other end is sealed, and has a cooling structure 6 for reducing the temperature of the coolant in the return pipe 4; a working pump 7: having a water cooling part 8, the water cooling part 8 having a cooling inlet 9 and a cooling outlet 10, the cooling inlet 9 is connected to the main water supply pipe 3, and the cooling outlet 10 is connected to the return pipe 4.

[0030] The water supply pool is provided with a cover plate 23 , and a flip handle 17 is fixedly provided on a side of the cover plate 23 away from the pool body 1 .

[0031] The main water supply pipe 3 is provided with a pressure sensor 16 . The pressure sensor 16 is signal-connected to the submersible pump 2 . The pressure sensor 16 is configured to detect the water pressure in the main water supply pipe 3 .

[0032] The main water supply pipe 3 is also provided with a filter 18 .

[0033] The cooling inlet 9 of the water cooling part 8 is arranged at a side close to the ground, and the cooling outlet 10 is arranged at the top of the water cooling part 8 .

[0034] The diameter of the main water supply pipe 3 is larger than that of the return pipe 4. When the working pump 7 is working, the water cooling unit 8 will take away a portion of the water in the main water supply pipe 3. If the diameters of the main water supply pipe 3 and the return pipe 4 are the same, it is easy to cause pressure imbalance between the main water supply pipe 3 and the return pipe 4.

[0035] The cooling inlet 9 is provided with a solenoid valve 22 .

[0036] The implementation method of the above embodiment is as follows: the coolant is water. When the working pump 7 connected to the main water supply pipe 3 and the return pipe 4 starts to work, the solenoid valve 22 opens, and the coolant in the main water supply pipe 3 flows into the water cooling part 8. The pressure sensor 16 detects that the pressure in the main water supply pipe 3 is reduced, and controls the submersible pump 2 to open and pump water into the main water supply pipe 3. The coolant enters from the cooling inlet 9 under the action of the submersible pump 2 and is discharged into the return pipe 4 from the cooling outlet 10. After being cooled by the cooling structure 6, the coolant flows back into the water supply tank to complete the cycle.

[0037] Example 2

[0038] The inner wall of the pool body 1 is provided with a first slot 11 , and the first slot 11 is detachably inserted into a coarse filter plate 12 . The coarse filter plate 12 separates the submersible pump 2 from the drainage end 5 of the return pipe 4 , and the coarse filter plate 12 is densely covered with filter holes 13 .

[0039] The inner wall of the pool body 1 is provided with a second slot 14 , and the second slot 14 can be detachably inserted into the water-blocking plate 15 .

[0040] The implementation of the above embodiment is as follows: Under normal circumstances, the baffle plate 15 is not installed in the second slot 14. The baffle plate 15 is only installed when the submersible pump 2 needs to be repaired. The coarse filter plate 12 can filter the coolant preliminarily to prevent the submersible pump 2 from being blocked by dirt. When the submersible pump 2 is repaired, the baffle plate 15 is inserted to evacuate the coolant on one side of the submersible pump 2. The staff can directly enter the water supply tank for repair without lifting the submersible pump 2.

[0041] Example 3

[0042] The cooling structure 6 is buried in a soil layer 1m to 3m below the ground surface. The cooling structure 6 includes a branch inlet pipe 19, a branch pipe 20 and a branch outlet pipe 21 along the flow direction of the coolant. There are multiple branch pipes 20, and the branch pipes 20 are connected between the branch inlet pipe 19 and the branch outlet pipe 21.

[0043] The implementation method of the above embodiment is as follows: the temperature of the soil layer 1m to 3m below the surface is relatively low and is not easily affected by the external temperature. When the coolant enters the water cooling part 8 of the working pump 7 and flows out, the temperature of the coolant rises, and the coolant enters the branch inlet pipe 19 from the return pipe 4, and then is divided into several streams from the branch inlet pipe 19 and enters the branch pipe 20. The design of multiple branch pipes 20 expands the heat exchange area between the cooling structure 6 and the underground soil, and also expands the heat dissipation area between the coolant and the branch pipe 20. The coolant can be fully cooled after flowing out of the cooling structure 6.
