Description

Technical Field

[0001] The utility model relates to the technical field of cutting pumps, in particular to a shearing type cutting pump. Background Art

[0002] The working principle of a shear pump relies on the shear force within it. When the fluid enters the pump body, the rotating blades or rotor of the pump generates a strong shear force. This shear force can cut, disperse and mix the molecules or particles in the fluid. Specifically, the shear pump cuts the bonds between molecules through high-speed rotating blades or impellers, resulting in brittle fracture, thereby achieving the purpose of rapid cutting, uniform dispersion and mixing. At present, the existing shear-type cutting pumps require a shear plate for shearing. However, due to the obstruction of the shear plate, the shear plate is easily blocked by soft objects such as bags or larger solid objects. When blocked, it will affect the delivery of the shear-type cutting pump, and there are certain shortcomings. For this reason, we propose a shear-type cutting pump. Utility Model Content

[0003] The utility model aims to solve the problems existing in the prior art or related technologies.

[0004] To this end, the technical solution adopted by the present invention is: a shear-type cutting pump, comprising a pump body, a base, a shear plate and an anti-blocking component, the base being bolted to the bottom of the pump body, a block being provided on the inner side of the base, the shear plate being inserted into the interior of the base, a drive motor being provided inside the shear plate, and a rotating shaft being provided at the output end of the drive motor, the anti-blocking component comprising a mounting seat inserted into the rotating shaft and fixedly connected to the rotating shaft by screws, a fixing rod arranged on both sides of the mounting seat, a spring arranged on the top of the fixing rod, a gear rod arranged on the top of the spring, and a brush arranged on the inner side of the gear rod.

[0005] Preferably, a water outlet pipe is provided on the outside of the pump body, and rotating blades are provided on the inside of the pump body.

[0006] Preferably, three through holes are provided on the outer side of the base, and the three through holes are distributed in a circle.

[0007] Preferably, a plurality of slots are provided on the outer side of the shear plate, and the shear plate is connected to the stopper through the slots.

[0008] Preferably, the height of the tops of several of the brush filaments is higher than that of the fixing rod, and the several brush filaments are bonded to the inner side of the fixing rod by strong glue.

[0009] Preferably, the anti-blocking component further comprises a sealing cover threadedly connected to the bottom of the mounting seat, and the outside of the mounting seat is provided with an external thread for connecting to the sealing cover.

[0010] By adopting the above technical scheme, the beneficial effects achieved by the utility model are as follows: the utility model realizes the anti-blocking effect by setting the shear plate and the anti-blocking component without affecting the use of the shear-type cutting pump, thereby preventing soft objects such as bags or larger solid objects from blocking the shear plate and affecting the delivery of the cutting pump, and at the same time facilitates the disassembly and replacement of the anti-blocking component. During use, the user can control the operation of the driving motor in the shear plate, and the running driving motor can drive the anti-blocking component to rotate through the rotating shaft. During the rotation of the anti-blocking component, the larger solid objects can be pushed by the gear lever. Due to the existence of centrifugal force, the solid objects will break away from the shear plate. At the same time, the elasticity of the spring makes the gear lever have a certain buffering effect, thereby preventing the gear lever from being damaged by a hard collision with the larger solid objects, and the brush wire can push soft objects such as bags, thereby facilitating the cutting of soft objects such as bags through the shear plate, thereby preventing soft objects such as bags or larger solid objects from blocking the shear plate and affecting the delivery of the cutting pump. When disassembly and replacement are required, the screw can be directly rotated until the screw is completely disengaged from the mounting seat, and then the mounting seat is moved away from the rotating shaft, and the anti-blocking component can be disassembled for replacement.

It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0022] The following describes some embodiments of the present invention in conjunction with the accompanying drawings to provide a shear-type cutting pump. Example 1

[0023] Reference Figure 1-5 , which is the first embodiment of the present utility model, provides a shear-type cutting pump, including a pump body 100, a base 200, a shear plate 300 and an anti-blocking component 400.

[0024] Specifically, a water outlet pipe 101 is provided on the outside of the pump body 100, and a rotating blade 102 is provided on the inside of the pump body 100. When in use, the water outlet pipe 101 can be connected to a delivery hose. After connection, the water outlet pipe 101 delivers the fluid into the delivery hose, and the delivery hose delivers it to a suitable position. The rotating blade 102 is also called a rotating blade and is used for cutting.

[0025] Specifically, the base 200 is bolted to the bottom of the pump body 100, a stopper 202 is provided on the inner side of the base 200, and three through holes 201 are provided on the outer side of the base 200. The three through holes 201 are distributed in a circle. When in use, the base 200 is docked at the bottom of the pump body 100 and fixed by bolts. After fixation, the base 200 can support the pump body 100 for placement, and the stopper 202 can block the shear plate 300 to install the shear plate 300. The three through holes 201 allow the fluid to enter the pump body 100 for shear transportation.

[0026] Specifically, the shear plate 300 is inserted into the interior of the base 200, and a drive motor 302 is provided inside the shear plate 300, and a rotating shaft 303 is provided at the output end of the drive motor 302. A number of slots 301 are provided on the outside of the shear plate 300, and the shear plate 300 is connected to the block 202 through the slots 301. When in use, the shear plate 300 can be aligned with the top of the base 200 and inserted. After insertion, the slot 301 can be engaged with the block 202 to fix the shear plate 300. After fixation, the shear plate 300 can block larger objects to protect the shear-type cutting pump, and then the drive motor 302 can be controlled to operate. The operating drive motor 302 can drive the anti-blocking component 400 to rotate through the rotating shaft 303, so as to clear the blockage on the shear plate 300 through the anti-blocking component 400.

[0027] Specifically, the anti-blocking component 400 includes a mounting base 401 inserted into the rotating shaft 303 and fixedly connected to the rotating shaft 303 by screws 402, fixed rods 404 arranged on both sides of the mounting base 401, a spring 405 arranged on the top of the fixed rod 404, a gear rod 406 arranged on the top of the spring 405, and a brush 407 arranged on the inner side of the gear rod 406. The height of the top of several brushes 407 is the same as that of the fixed rod 404, and several brushes 407 are bonded to the inner side of the fixed rod 404 by strong glue. When in use, the running drive motor 302 can drive the anti-blocking component 400 to rotate through the rotating shaft 303. During the rotation of the anti-blocking component 400, a larger Solid objects can be separated from the shear plate 300 due to the existence of centrifugal force. At the same time, the elasticity of the spring 405 makes the gear lever 406 have a certain buffering effect, thereby preventing the gear lever 406 from being damaged by a hard collision with a larger solid object. The brush wire 407 can push soft objects such as bags, making it convenient for soft objects such as bags to be cut through the shear plate 300, thereby preventing soft objects such as bags or larger solid objects from clogging the shear plate 300 and affecting the delivery of the cutting pump. When disassembly and replacement are required, the screw 402 can be directly rotated until the screw 402 is completely separated from the mounting seat 401, and then the mounting seat 401 can be moved to separate from the rotating shaft 303, and the anti-blocking component 400 can be disassembled for replacement. Example 2

[0028] Reference Figure 4 , which is the second embodiment of the present utility model, which is different from the first embodiment in that: the anti-blocking component 400 also includes a sealing cover 403 threadedly connected to the bottom of the mounting base 401, and the outside of the mounting base 401 is provided with an external thread for connecting the sealing cover 403. When in use, the sealing cover 403 can be aligned with the bottom of the mounting base 401, and then rotated to connect. After connection, the mounting base 401 can be sealed by the sealing cover 403, so that the screws 402 in the mounting base 401 do not contact water, thereby delaying the corrosion time and extending the service life.

[0029] The working principle and usage process of the present invention are as follows: when in use, the user can control the operation of the driving motor 302 in the shear plate 300. The operating driving motor 302 can drive the anti-blocking component 400 to rotate through the rotating shaft 303. During the rotation of the anti-blocking component 400, the gear lever 406 can push larger solid objects. Due to the existence of centrifugal force, the solid objects can be separated from the shear plate 300. At the same time, the elasticity of the spring 405 makes the gear lever 406 have a certain buffering effect, avoiding the gear lever 406 from being damaged by a hard collision with the larger solid objects, and the brush wire 407 can push soft objects such as bags, making it convenient for soft objects such as bags to be cut through the shear plate 300, avoiding soft objects such as bags or larger solid objects from blocking the shear plate 300 and affecting the delivery of the cutting pump. When disassembly and replacement are required, the screw 402 can be directly rotated until the screw 402 is completely separated from the mounting seat 401, and then the mounting seat 401 is moved to separate from the rotating shaft 303, and the anti-blocking component 400 can be disassembled for replacement.
