[0022] The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0023] As shown in Figure 1 The utility model discloses a circulating water cooling device for conveying pump, including the water tank 1 for containing water, circulating pump 2 and heat exchanger 3, the outlet pipeline of circulating pump 2 is equipped with pressure detection element 4, the water tank 1 is transported to heat exchanger 3 through pipeline and circulating pump 2, is used to cool the water of circulating pump 2 output, the outlet of heat exchanger 3 is connected with the water seal inlet of the conveying pump 00 to be cooled, and the water seal outlet of the conveying pump 00 to be cooled is connected with the water tank 1 through the backwater pipeline, the top of water tank 1 is equipped with cooling filter structure, is used to filter the water of backwater pipeline and flows into the water tank 1 in the dispersed state. The water in the water tank is transported to the heat exchanger by the circulating pump and enters the water seal of the conveying pump to be cooled after cooling, which plays a cooling role on the conveying pump. The water that is heat exchanged and heated with the conveying pump flows back to the water tank. The cooling filter structure makes the heated water flow into the water tank in a dispersed state, and the water is preliminarily cooled and filtered during the dispersion process.

[0024] As a preferred structure, as shown in Figure 1 、 Figure 2 The cooling filter structure includes a water collecting hopper 5 and an umbrella-shaped water distribution cover 6. The water collecting hopper 5 is arranged on the top cover of the water tank 1, the upper end of the water collecting hopper 5 is connected with the backwater pipeline, and the diameter of the water collecting hopper 5 is larger than that of the backwater pipeline. The lower end of the water collecting hopper 5 is arranged at the middle inlet end of the water distribution cover 6. The periphery of the water distribution cover 6 is connected with the side wall of the water tank 1 through a connecting piece. The water distribution cover 6 is covered with mesh screens capable of leaking water downward. The water distribution cover 6 is in the shape of a conical frustum. The upper surface of the water distribution cover 6 is provided with a plurality of spiral ridges 7. Adjacent two spiral ridges 7 form spiral flow guide grooves. The water in the backwater pipeline enters the water collecting hopper. Due to the increase in diameter and the decrease in flow rate, the water flows down along the several flow guide grooves on the surface of the water distribution cover. With the help of the spiral flow guide grooves, the water speed is further reduced. The water can leak down along the mesh screens, and part of the impurities can be intercepted at the lower periphery of the water distribution cover. The impurities can be cleaned later.

[0025] Further optimization of the above scheme, the outlet side of water tank 1 is equipped with filter screen 8, and the water distribution cover 6 and the water tank 1 outlet are arranged on both sides of the filter screen 8. The water in the water tank is filtered through the filter screen and then enters the circulating pump, which can protect the circulating pump and the heat exchanger and prevent the circulating pump and the heat exchanger from being blocked.

[0026] In the embodiment, the heat exchanger 3 is a plate heat exchanger, and the cooling medium of the plate heat exchanger can be the existing cooling water in the workshop, without laying another pipeline; the pressure detection element 4 is a pressure alarm, which can timely alarm when the outlet pressure of the circulating pump is reduced, so that the technical personnel can take measures; the water in the water tank 1 is purified water, which has higher purity and can reduce the damage to the circulating pump, the heat exchanger and the delivery pump, and the purified water can be replaced when the water in the water tank appears turbidity.

[0027] In another embodiment of the present application, as shown in Figure 3 two water tanks 1 are arranged side by side, the inlets of the two water tanks 1 are connected in parallel with the return water pipeline, and the outlets of the two water tanks 1 are connected in parallel with the inlet end of the circulating pump 2. The two water tanks can realize continuous cooling of the delivery pump, and the water in the water tanks can be alternately replaced without stopping and waiting.

[0028] In summary, the present application has the advantages of simple structure and good cooling effect. The purified water in the water tank is delivered to the heat exchanger by the circulating pump for cooling, and then enters the water seal of the delivery pump to be cooled. The water after heat exchange with the delivery pump is returned to the water tank to realize circulation. Meanwhile, the water returned is dispersed by the water collecting and distributing device on the top of the water tank, and flows down along the guide groove of the water distributing cover to preliminarily cool the heated water and filter the water. The present application can effectively cool the delivery pump, filter the water in the circulation process, and effectively prolong the service life of the circulating pump, the heat exchanger and the delivery pump.

[0029] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can be modified to the technical solutions recorded in the foregoing embodiments, or equivalent replacement of some technical features.
