The output end of the motor 100 is connected with a central rod 110, the central rod 110 is connected with a spiral propelling blade 111 which extends spirally along the axis of the central rod 110, and the motor 100 drives the central rod 110 and the spiral propelling blade 111 to rotate so as to realize the spiral propelling effect. The pump barrel 200 is coaxially sleeved on the spiral propelling blade 111, the inner diameter of the pump barrel 200 is matched with the spiral diameter of the spiral propelling blade 111, preferably in clearance fit, so that the friction resistance can be reduced, one end of the pump barrel 200 is hermetically connected with the motor 100, the other end of the pump barrel 200 is provided with the sludge outlet 220, one end of the pump barrel 200 is fixedly connected (welded or bolted) with the shell of the motor 100, the outlet of the end of the pump barrel 200 is sealed by the motor 100, and the other end of the pump barrel serves as the sludge outlet 220. The end of the side wall of the pump barrel 200 far away from the sludge outlet 220 is provided with a sludge inlet 210, and sludge enters from the sludge inlet 210 and is pushed by the spiral pushing blade 111 towards the sludge outlet 220 to realize a pumping effect.
The cooling cylinder 300 is coaxially sleeved on the pump cylinder 200, the inner wall of the cooling cylinder 300 is attached to the outer wall of the pump cylinder 200, the inner wall of the cooling cylinder 300 is respectively provided with a first spiral groove 310 and a second spiral groove 320 which extend spirally in parallel, the first spiral groove 310 and the second spiral groove 320 are formed by spirally extending the first spiral groove 310 and the second spiral groove 320 along the axial direction of the cooling cylinder 300, the first spiral groove 310 and the second spiral groove 320 are formed by inwards sinking the inner wall of the cooling cylinder 300, so that the first spiral groove 310 and the second spiral groove 320 form two independent flow passages with the outer wall of the pump cylinder 200, then the first spiral groove 310 and the second spiral groove 320 are circularly filled with the cooling liquid in the cooling liquid tank 400 through the circulating driving mechanism, generally, the cooling liquid flowing into the first spiral groove 310 and the second spiral groove 320 is relatively cold at the beginning, and the temperature of the cooling liquid is relatively high at the end with the long contact time with the outer wall of the pump cylinder, for this reason, the circulation paths of the first spiral groove 310 and the second spiral groove 320 are set to be opposite paths, which is effective for improving the cooling, and the cooling is more uniform and the cooling effect is better.
In this embodiment, the cooling cylinder 300 is formed by splicing a first semi-cylinder 301 and a second semi-cylinder 302. Specifically, a first skirt edge 3011 and a second skirt edge 3021 extend outwards from two sides of the first semi-cylinder 301 and the second semi-cylinder 302, and the first skirt edge 3011 and the second skirt edge 3021 are provided with corresponding bolt holes for connection and fixation through bolts 700. The first spiral groove 310 and the second spiral groove 320 are formed by splicing corresponding grooves on the inner walls of the first semi-cylinder 301 and the second semi-cylinder 302. In order to improve the sealing property, gaskets are arranged on the joint surfaces of the first skirt edge 3011 and the second skirt edge 3021.
The cooling tank is used for storing cooling liquid, and the cooling liquid can be common water or other media. The heat is absorbed by the water, the water circulates among the cooling box, the first spiral groove 310 and the second spiral groove 320, and the heat absorbed by the water exchanges heat with the outside in the cooling box due to the fact that the cooling box has a large contact area with the outside, and continuous heat dissipation is achieved. At this time, a cooling fan can be added to blow the water in the cooling tank, and the water is cooled through liquefaction. In other embodiments, a refrigerator 500 may be installed in the cooling liquid tank 400 to cool the liquid to improve the heat dissipation cooling effect.
The cooling circulation structure is that one end (left end in view of fig. 1) of the side wall of the cooling cylinder 300 is provided with a first inlet 311 communicated with one end of the first spiral groove 310 and a second outlet 322 communicated with one end of the second spiral groove 320, and the other end (right end in view of fig. 1) of the side wall of the cooling cylinder 300 is provided with a first outlet 312 communicated with the other end of the first spiral groove 310 and a second inlet 321 communicated with the other end of the second spiral groove 320. The circulating driving mechanism comprises a first water inlet pipe 3111, a first water outlet pipe 3121, a second water inlet pipe 3211, a second water outlet pipe 3221, a first circulating pump 3112 and a second circulating pump 3212; one end of the first water inlet pipe 3111 is communicated with the first inlet 311, and the other end extends into the cooling liquid; one end of the second water inlet pipe 3211 is communicated with the second inlet 321, and the other end extends into the cooling liquid; the first water outlet pipe 3121 and the second water outlet pipe 3221 are respectively communicated with the first outlet 312 and the second outlet 322 for feeding the cooling liquid back to the cooling liquid tank 400; the first circulation pump 3112 and the second circulation pump 3212 are installed on the first inlet pipe 3111 and the second inlet pipe 3211, respectively. In order to avoid that the heat-absorbed water directly enters the first spiral groove 310 or the second spiral groove 320 again, the first water outlet pipe 3121 and the second water outlet pipe 3221 are respectively located at two sides in the coolant tank 400 and are higher than the liquid level of the coolant, the first water inlet pipe 3111 and the second water inlet pipe 3211 are located in the middle of the coolant tank 400, so that the heat-absorbed water enters the edge in the coolant tank 400, and the middle water circularly enters the first spiral groove 310 or the second spiral groove 320, thereby avoiding the influence of uneven temperature of the liquid in the coolant tank 400 on the cooling effect. It is understood that the refrigerator 500 is located in the middle of the cooling liquid tank 400 so that the temperature in the middle is the lowest, which is beneficial to cooling and heat dissipation.
In order to achieve good sealing and avoid the coolant from slipping out from between the pump barrel 200 and the cooling barrel 300, a sealing ring 600 is arranged between the inner wall of the cooling barrel 300 and the outer wall of the pump barrel 200 and is positioned at two sides of the first spiral groove 310 and the second spiral groove 320.
The above embodiments are only used for illustrating the technical solutions of the present invention and are not limited thereto, and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of the technical solutions of the present invention.
