Description

Technical field

[0001] The utility model belongs to the technical field of slurry pumps, and in particular relates to a slurry pump agitator for a coal-water separation system. [Background Technology]

[0002] Coal-water separation systems are primarily used underground in coal mines. Using equipment such as vibrating grading dewatering screens, sedimentation tanks, and filter presses, they separate the water from the coal transported from the mining face, solving transportation and storage challenges. This system has been used in various coal mining areas and has effectively improved work efficiency and safety.

[0003] Slurry pumps in coal-water separation systems are used to transport the coal-water mixture to a solid-liquid separation device to separate the coal and water. The slurry pump's structure primarily consists of a pump body, pump cover, impeller, jacket, and guard plate. The impeller, driven by an electric motor, rotates at high speed, generating centrifugal force that propels the liquid from the center of the impeller to the outer edges, generating kinetic and pressure energy. The slurry pump operates by rotating the impeller at high speed, generating centrifugal force that propels the liquid from the center of the impeller to the outer edges, generating energy. Upon entering the volute pump casing, the liquid decelerates, converting kinetic energy into static pressure energy, and ultimately flows into the discharge pipe at a higher pressure. Slurry pumps are typically placed in a silo. Because the silt coal in the silo is relatively viscous, this often leads to blockage of the slurry pump's inlet. [Utility Model Content]

[0004] The utility model aims to provide a slurry pump agitator for a coal-water separation system, so as to solve the problem that the inlet of the existing slurry pump is easily blocked.

[0005] The utility model adopts the following technical solution: a slurry pump agitator of a coal-water separation system comprises a C-shaped casing, both ends of the casing are open, a water inlet hole is opened on the casing body at the middle position of the total length, and a plurality of drainage holes are evenly opened on the casing body at both sides of the water inlet hole;

[0006] Among them, the water inlet hole is used to connect to the water pipe through the straight-through and high-pressure hoses in sequence to complete the water inlet; each drainage hole and both ends of the casing are used to discharge the water in the casing;

[0007] The casing is used to surround the outside of the water inlet pipe of the slurry pump, and the center of the casing is coaxial with the water inlet pipe of the slurry pump; the casing is used to use the water flow from its inside to the outside to stir and dilute the slurry at the water inlet of the slurry pump, thereby reducing the blockage of the slurry pump and the water pipe.

[0008] Furthermore, the radius of the bending arc of the sleeve is 450 mm to 550 mm.

[0009] Furthermore, the water inlet hole is a 6-point hole with a diameter of 20 mm.

[0010] The beneficial effects of the present invention are as follows: by providing a C-shaped casing and setting a water inlet, a drain hole, and a water outlet on the casing, the water flowing out from the inside of the casing 1 can stir and dilute the slurry at the water inlet of the slurry pump, blowing away the surrounding coal and water, and preventing the slurry pump from being blocked by deposited coal silt, thereby reducing the viscosity of the slurry entering the water inlet of the slurry pump and reducing the probability of blockage of the slurry pump and water pipes. At the same time, the slurry pump agitator of the coal-water separation system has a simple structure, is easy and convenient to use, has low cost and low maintenance cost, and is particularly practical in the use of 37KW slurry pumps.

[0012] Among them, 1. casing, 2. drainage hole, 3. water inlet hole, 4. water outlet. [Specific implementation method]

[0013] The present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0014] The utility model provides a slurry pump agitator for a coal-water separation system, such as Figure 1 As shown, it comprises a C-shaped sleeve 1 with two open ends, which serve as water outlets 4. A water inlet 3 is provided on the sleeve 1 at the middle of its total length, and a plurality of drainage holes 2 are evenly provided on the sleeve 1 on both sides of the water inlet 3.

[0015] Among them, the water inlet hole 3 is used to connect to the water pipe through a straight-through and high-pressure hose in sequence to complete water intake; each of the drainage holes 2 and both ends of the sleeve 1 are used to discharge the water in the sleeve 1.

[0016] The sleeve 1 is used to be arranged around the outside of the water inlet pipe of the slurry pump, and the center of the sleeve 1 is coaxial with the water inlet pipe of the slurry pump; the sleeve 1 is used to use the water flow from its inside to the outside to stir and dilute the slurry at the water inlet of the slurry pump, thereby reducing the blockage of the slurry pump and the water pipe.

[0017] In some embodiments, the radius of the bending arc of the sleeve 1 is 450 mm to 550 mm.

[0018] In some embodiments, the water inlet hole 3 is a 6-point hole with a diameter of 20 mm.

[0019] Taking a 37KW slurry pump as an example, the method of using the slurry pump agitator of the utility model coal-water separation system is as follows:

[0020] To dilute the silted coal and ensure the normal feeding of the 37KW slurry pump, a coal-water separation system slurry pump agitator of this utility model was installed at the inlet of the 37KW slurry pump. The water inlet hole 3 is a 6-point hole, to which a 400mm long 6-point welded pipe is welded, and a 19# straight-through pipe is welded. The straight-through pipe is then connected to a 19# high-pressure hose. The high-pressure hose is connected to the water pipe and a stop valve is installed to control the water flow.

[0021] Turn on the slurry pump agitator of the coal-water separation system. Water flows from the water pipe, high-pressure hose and straight-through water inlet 3 into the casing 1, then flows out from the two water outlets 4 and sprays out from each drainage hole 2 at the same time.

[0022] Turn on the coal-water separation system slurry pump agitator for 3-4 minutes before turning on the slurry pump;

[0023] The water flowing out from the inside of the casing 1 can stir and dilute the slurry at the water inlet of the slurry pump, blow away the surrounding coal and water, and prevent the deposited silt coal from clogging the slurry pump, thereby reducing the viscosity of the slurry entering the water inlet of the slurry pump and reducing the probability of clogging the slurry pump and the water pipe.

[0024] The drainage hole 2 and two water outlets 4 of the agitator are used to discharge water, dilute the viscosity of the silted coal at the feed inlet of the 37KW slurry pump, facilitate the normal feeding of the 37KW slurry pump, clean the silted coal in the water tank, and ensure disaster control work.
