Description

Technical Field

[0001] This utility model relates to the field of crystal slurry pump technology, and more specifically, to a crystal slurry pump with a fully open impeller structure. Background Technology

[0002] A crystal slurry pump is a special type of pump used to transport crystal slurry, which refers to a suspension of crystals and mother liquor. It has important applications in crystallization processes in industries such as chemical, pharmaceutical, and food processing. Crystal slurry pumps typically operate on the principle of centrifugal pumps, using the rotation of an impeller to generate centrifugal force, drawing the crystal slurry into the pump inlet. The impeller then energizes the slurry, discharging it from the pump outlet. The impeller is usually designed as a fully open, semi-open, or closed type to prevent clogging when transporting liquids with a certain viscosity and high concentration of crystals, while also improving working efficiency.

[0003] However, after a period of use, existing crystal slurry pumps often have some material residue on the surface of the impeller and other structures inside the pump because the material being transported is usually a suspension of crystals and mother liquor with a certain viscosity. This requires disassembling and assembling the pump body bolts for cleaning, which is cumbersome and inconvenient. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a crystal slurry pump with a fully open impeller structure to solve the problem that since the material being transported is usually a suspension of crystals and mother liquor with a certain viscosity, some material will remain on the surface of the impeller and other structures inside the pump, which requires disassembling and assembling the pump body bolts for cleaning, which is cumbersome and inconvenient.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fully open impeller structure crystal slurry pump, including a crystal slurry pump body, a first delivery pipe connected to the input flange of the crystal slurry pump body, a second water delivery pipe connected to the output flange of the crystal slurry pump body, the first delivery pipe and the second water delivery pipe being connected through a flushing pipe, a first valve being provided on the side of the first delivery pipe away from the crystal slurry pump body and the flushing pipe, a second valve being provided on the side of the second water delivery pipe away from the crystal slurry pump body and the flushing pipe, and a water hammer assembly being provided on the flushing pipe.

[0006] Preferably, the water hammer assembly includes a water hammer column, with pistons fixedly installed at both the upper and lower ends of the water hammer column. The water hammer column and pistons are slidably connected within a flushing pipe. A vertical sliding groove is provided on one side of the flushing pipe. A T-shaped slider is fixedly installed at the middle of the outer side of the water hammer column. A horizontal sliding groove is provided on the outer side of the T-shaped slider. A sleeve is fixedly installed on the flushing pipe. A drive frame is fixedly installed on the outer side of the sleeve. A drive motor is fixedly installed in the middle of the drive frame. A turntable is fixedly connected to the output end of the drive motor. A sliding column is fixedly installed at the eccentric part of the turntable and slidably installed within the horizontal sliding groove.

[0007] Preferably, the length of the water hammer column is greater than the length of the vertical sliding groove, and during the sliding of the T-shaped slider in the vertical sliding groove, the water hammer column always blocks the vertical sliding groove to prevent water from flowing out of the vertical sliding groove, and the piston is made of rubber material.

[0008] Preferably, the first conveying pipe has a first filter hole corresponding to one end of the flushing pipe, and the second water conveying pipe has a second filter hole corresponding to the other end of the flushing pipe. The first filter hole and the second filter hole are used to intercept the crystal slurry material.

[0009] Preferably, a third valve is provided at the end of the flushing pipe near the first delivery pipe, and a fourth valve is provided at the end of the flushing pipe near the second water delivery pipe.

[0010] Preferably, a drainage assembly is provided on the outside of the flushing pipe, and the drainage assembly is located above the water hammer assembly.

[0011] Preferably, the drainage assembly includes a drain pipe, which is fixedly connected to the flushing pipe and located above the water hammer assembly. A plug is detachably and slidably inserted into the drain pipe. A threaded hole is provided on the side of the drain pipe away from the flushing pipe. A bolt is provided on the plug, and the bolt is detachably threaded into the threaded hole.

[0012] Preferably, both the drain pipe and the plug are T-shaped, and the portion of the plug inserted into the drain pipe is made of rubber.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention involves closing the second valve and injecting cleaning fluid into the first delivery pipe. Once the first delivery pipe, the second water delivery pipe, and the flushing pipe are filled with cleaning fluid, the first valve is closed, and the drive motor is started. This causes the water hammer column to move vertically up and down repeatedly, thereby driving the cleaning fluid in the first delivery pipe, the second water delivery pipe, and the flushing pipe to flush back and forth, cleaning the impeller and other structures inside the crystal slurry pump body. There is no need to disassemble the crystal slurry pump body, making the operation simple and convenient.

[0015] This invention allows the cleaning fluid to be discharged from the drain pipe under gravity by removing the bolts and then taking the plug out of the drain pipe, thus avoiding residual water in the flushing pipe and preventing bacterial growth. Attached Figure Description

A sliding column 710 is fixedly installed at the eccentric part of the turntable 79. The sliding column 710 is slidably installed within the horizontal sliding groove 75.

[0027] Preferably, the length of the water hammer column 71 is greater than the length of the vertical slide groove 73, and during the sliding of the T-shaped slider 74 in the vertical slide groove 73, the water hammer column 71 always blocks the vertical slide groove 73 to prevent water from flowing out of the vertical slide groove 73, and the piston 72 is made of rubber material.

[0028] Specifically, by closing the second valve 6, cleaning fluid is injected into the first delivery pipe 2. After the first delivery pipe 2, the second water delivery pipe 3, and the flushing pipe 4 are filled with cleaning fluid, the first valve 5 is closed, and the drive motor 78 is started. The drive motor 78 drives the sliding column 710 on the turntable 79 to move in a circle. The sliding column 710 drives the water hammer column 71 to move vertically up and down repeatedly through the horizontal sliding groove 75, thereby driving the cleaning fluid in the first delivery pipe 2, the second water delivery pipe 3, and the flushing pipe 4 to flush back and forth, cleaning the impeller and other structures inside the crystal slurry pump body 1.

When conveying materials, the third valve 8 and the fourth valve 9 are closed to make the conveying path more singular and avoid affecting the material conveying.

[0031] Preferably, a drainage component 10 is provided on the outside of the flushing pipe 4, and the drainage component 10 is located above the water hammer component 7.

[0032] Preferably, the drainage assembly 10 includes a drain pipe 101, which is fixedly connected to the flushing pipe 4 and is located above the water hammer assembly 7.

[0034] Specifically, after rinsing, some cleaning fluid will remain in the upper part of the rinsing pipe 4. At this time, by removing the bolt 104 and then removing the plug 102 from the drain pipe 101, the cleaning fluid will be discharged from the drain pipe 101 under the action of gravity, thus preventing residual water in the rinsing pipe 4 from causing bacterial growth.

[0035] The working process of this utility model is as follows:
