Description

Technical Field

[0001] The utility model belongs to the field of cooling equipment, in particular to a pump machine seal cooling circulation device. Background Art

[0002] The pump is usually composed of a turbine part and a motor part. The turbine and the motor are connected by a transmission shaft. The connection part needs to be mechanically sealed to prevent the material extracted by the turbine from penetrating into the motor and causing damage. The position of the pump seal is prone to friction and heating. Excessive heat accumulation will cause damage to the pump, so the seal position is usually cooled. Common cooling methods include air cooling and water cooling, but whether it is air cooling or water cooling, when the temperature is too high in summer, the temperature of the cooling medium will also rise rapidly, so that the heat dissipation effect is not ideal. Therefore, it is necessary to provide a local mechanical seal cooling circulation device that maintains the cooling medium at a low temperature. Utility Model Content

[0003] The utility model aims to provide a pump machine seal cooling circulation device to solve the technical problem that when the temperature is too high in summer, the temperature of the cooling medium will rise rapidly and the heat dissipation effect is not ideal, whether it is air cooling or water cooling.

[0004] To achieve the above purpose, the specific technical solution of the utility model is as follows:

[0005] A pump seal cooling circulation device comprises: a cooling tower: provided with a cooling element, wherein a cooling medium circulates in the cooling element, wherein the cooling element is arranged along the height direction and / or the horizontal direction of the cooling tower, and the projection area of ​​the cooling element in the height direction of the cooling tower accounts for at least 60% of the cross-sectional area of ​​the cooling tower; a water storage tank: provided below the cooling tower along the falling direction of the coolant and connected with the cooling tower; a water cooling part: sealed and surrounded on the outer periphery of the pump seal, and having a water inlet and a water outlet; a water pump: connected between the water storage tank and the water inlet, provided with a water pump, wherein the water pump is configured to extract the coolant in the water storage tank and inject it into the water cooling part; a drainage pipe: connected between the water outlet and the cooling tower. Through such a design, the coolant cools the seal position and then enters the cooling tower from the drainage pipe. After the cooling tower quickly reduces the temperature of the coolant, the coolant is stored in the water storage tank. The coolant supplied by the water storage tank to the water cooling part is always kept at a relatively low temperature, which greatly improves the heat dissipation effect.

[0006] Furthermore, the cooling element is tubular, and includes a vertical pipeline arranged in an S shape along the height of the cooling tower close to the inner wall of the cooling tower, and a transverse pipeline arranged in the horizontal direction of the cooling tower, and the transverse pipeline is arranged in at least two layers, and the conveying directions of the two layers of the transverse pipeline are cross-shaped, and the cooling medium is cold air, and the two ends of the cooling element extend out of the cooling tower and are connected to the cold air source. Through such a design, the transverse pipeline is laid in the direction of the coolant falling, and when the coolant falls, it will adhere to the outer wall of the cooling element, and the cold air in the cooling element will exchange heat with the cooling element, and the coolant will exchange heat with the cooling element, thereby reducing the temperature of the coolant.

[0007] Furthermore, the drain pipe is provided with an atomizing nozzle at one end of the cooling tower, and the spraying direction of the atomizing nozzle matches the cooling element. Through such a design, the atomizing nozzle sprays the coolant in atomized form, so that the coolant is evenly attached to the outer wall of the cooling element, thereby expanding the heat exchange area.

[0008] Furthermore, a blowing port is provided on one side of the inner wall of the cooling tower close to the atomizing nozzle, and the air outlet direction of the blowing port matches the water sprayed by the atomizing nozzle. Through such a design, the blowing port further diffuses the coolant, and the blowing port can also cool the coolant through air cooling.

[0009] Furthermore, the cooling tower is also provided with a striking blade, which includes a driving rod and a paddle, one end of the driving rod is fixedly connected to the bottom of the water storage bucket, and the other end is fixedly installed with a paddle and extends into the enclosure of the vertical pipeline. Through such a design, the striking blade drives the airflow in the cooling tower to move and hits the falling coolant onto the vertical pipeline.

[0010] Furthermore, a liquid guiding structure is provided at the connection between the cooling tower and the water storage barrel, and the liquid guiding structure gradually converges into a frustum shape along the falling direction of the coolant. With such a design, the coolant continues to fall after being cooled by the cooling element, and the frustum design of the liquid guiding structure can more smoothly guide the coolant attached to the inner wall of the cooling tower into the water storage barrel.

[0011] Furthermore, the water storage barrel is provided with a thermal insulation layer. Through such a design, the thermal insulation layer can effectively prevent the coolant in the water storage barrel from exchanging heat with the external environment through the water storage barrel wall, thereby reducing the influence of the external environment on the temperature of the coolant in the water storage barrel.

[0012] Furthermore, the water inlet of the water cooling part is arranged at the lower side of the water cooling part in the height direction, and the water outlet is arranged at the top of the water cooling part. With such a design, the coolant enters the water cooling part from the bottom and exits from the top, so that the coolant is efficiently utilized.

[0013] Furthermore, the drain pipe is provided with a filter. With such a design, when the mechanical seal rotates for a long time, a small amount of materials pumped by the pump will leak into the water cooling part through the mechanical seal and agglomerate, and the agglomerated materials will enter the drain pipe along with the coolant, and the filter can filter out the agglomerated materials.

[0014] The beneficial effects of the utility model are as follows: the coolant cools down the mechanical seal position and then enters the cooling tower from the drain pipe. The cooling tower quickly reduces the temperature of the coolant and then stores the coolant in the water storage barrel. The coolant supplied by the water storage barrel to the water cooling part always maintains a relatively low temperature, which greatly improves the heat dissipation effect.

[0026] The cooling member 2 is tubular, and includes a vertical pipeline 10 arranged in an S shape along the height of the cooling tower 1 and close to the inner wall of the cooling tower 1, and a transverse pipeline 11 arranged in the horizontal direction of the cooling tower 1. The transverse pipeline 11 is provided with at least two layers, and the conveying directions of the two layers of the transverse pipelines 11 are cross-shaped. The cooling medium is cold air, and both ends of the cooling member 2 extend out of the cooling tower 1 and are connected to the cold air source.

[0027] A liquid guiding structure 17 is provided at the connection between the cooling tower 1 and the water storage barrel 3 , and the liquid guiding structure 17 gradually converges into a frustum shape along the falling direction of the cooling liquid.

[0028] The water storage barrel 3 is provided with a temperature insulation layer 18 .

[0029] The water inlet 5 of the water cooling part 4 is arranged at a lower side of the water cooling part 4 in the height direction, and the water outlet 6 is arranged at the top of the water cooling part 4 .

[0030] The drain pipe 8 is provided with a filter 19 .

[0031] The implementation method of the above embodiment is as follows: the pumping pipe 7 draws the coolant (water) from the water storage barrel 3 and enters the water cooling part 4. The coolant cools the mechanical seal and is then drawn out by the drain pipe 8. The drain pipe 8 injects the coolant from the top of the cooling tower 1. The coolant falls with gravity. The cooling element 2 is in the falling direction of the coolant. The coolant falls on the cooling element 2 for heat exchange and cooling, then falls through the gap of the cooling element 2 and is then introduced into the water storage barrel 3 by the liquid guide structure 17.

[0032] Example 2

[0033] The drain pipe 8 is located at one end of the cooling tower 1 and is provided with an atomizing nozzle 12 , and the water spraying direction of the atomizing nozzle 12 matches the cooling element 2 .

[0034] An air outlet 13 is provided on one side of the inner wall of the cooling tower 1 close to the atomizing nozzle 12 , and the air outlet direction of the air outlet 13 matches the water sprayed by the atomizing nozzle 12 .

[0035] The implementation of the above embodiment is as follows:

Since the transverse pipe 11 is in the direction of the coolant falling and occupies a large area, most of the coolant will fall into the transverse pipe 11. A small amount of coolant that has not been cooled and the coolant that has dripped after being cooled by the transverse pipe 11 fall from the gap in the transverse pipe 11. The coolant enters the space enclosed by the vertical pipe 10, hits the blades 14 and slaps the falling coolant onto the vertical pipe 10, and the vertical pipe 10 cools the coolant again.
