Description

Technical Field

[0002] A low-speed filter press slurry pump is a pump specifically used for transporting slurry containing solid particles or corrosive liquids.

[0003] Currently, the chambers for loading impellers in low-speed filter press slurry pumps are mostly made of metal. However, the structure of the metal impeller chambers is complex. Especially for closed impellers, the processing precision requirements for their internal flow channels and blades are extremely high. Traditional processing methods are difficult to accurately form the internal blades, resulting in a significant increase in manufacturing difficulty and cost. In addition, there are also problems such as difficult removal of the support structure, high surface roughness, and complex post-treatment, which cause the impeller to be easily corroded and worn in a harsh working environment. For example, when transporting corrosive media or fluids containing particles, pits, wear, or even structural damage may occur on the impeller surface. And currently, during the object transportation process, the speed is slow, thus reducing the transportation efficiency of the filter press slurry pump. Therefore, a low-speed filter press slurry pump is proposed for the above problems. Summary of the Invention

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] For the embodiment, please refer to Figures 1 - 6 , the present invention provides a technical solution:

[0028] A low-speed pressure filter slurry pump includes a main body 1; a support and moving component 2 is arranged at the bottom of the main body 1, and a slurry pump component 3 and a stirring and boosting component 4 are fixedly connected to the top of the main body 1.

[0029] In this embodiment, as shown in Figure 1 and Figure 2As shown in the figure, the pulp pump assembly 3 includes a bracket 301. A motor 302 is installed at the top of the bracket 301. The output end of the motor 302 is fixedly connected to a coupling rod 306. An impeller 307 is fixedly connected to the side of the coupling rod 306. There are several brackets 301. A ultra-high molecular weight polyethylene bin 309 is installed at the top of the bracket 301. The impeller 307 is arranged inside the ultra-high molecular weight polyethylene bin 309. A heat insulation cover 308 is fixedly connected to the side of the ultra-high molecular weight polyethylene bin 309. With the structural design of using the ultra-high molecular weight polyethylene bin 309 as the bin body for placing the impeller 307 of the speed filtration slurry pump, the function of excellent corrosion resistance and wear resistance is realized when the speed filtration slurry pump is rotating and conveying, solving the problems of wear of the impeller 307 and the pump body and short service life, and improving the efficiency of the speed filtration slurry pump for conveying slurry or corrosive liquid containing solid particles.

[0030] In this embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, the stirring and boosting assembly 4 includes a support frame 401. A tank body 402 is fixedly connected to the top of the support frame 401. A delivery pipe 411 is fixedly connected to the bottom of the tank body 402. An electric control actuating valve 410 is fixedly connected to the bottom of the delivery pipe 411. The driving stirring motor 404 drives the rotating rod 405 to rotate, so that the stirring blades 406 stir the objects input into the tank body 402 from the feeding pipe 407. After stirring, the electric control actuating valve 410 is controlled to convey the objects. When flowing into the booster 409, the booster 409 will boost the flow rate of the objects, accelerating the flow rate of the objects, thereby increasing the conveying efficiency. The boosted objects will flow into the ultra-high molecular weight polyethylene bin 309 from the feed pipe 312. A supporting plate 408 is arranged inside the support frame 401. A booster 409 is installed at the top of the supporting plate 408. The delivery pipe 411 extends into the booster 409. With the structural design of installing the booster 409 on the output pipeline, the function of driving low-pressure fluid to generate high-pressure fluid output is realized, solving the problem of slow conveying rate of the speed filtration slurry pump for conveying objects, and improving the adaptability of significantly boosting the pressure of low-pressure fluid to output high-pressure fluid and meeting the demand for high pressure in industrial production.

[0031] A connecting frame 304 is fixedly connected to the top of the bracket 301. A protective cover 305 is fixedly connected to the top of the connecting frame 304. The coupling rod 306 is arranged inside the protective cover 305. The protective cover 305 can protect the coupling rod 306 to prevent dust from entering it and affecting the rotation.

[0032] The top of the motor 302 is fixedly connected to a brake box 303. Inside the ultra-high molecular weight polyethylene bin 309, a sealing gasket 311 is fixedly connected. Inside the sealing gasket 311, a feed pipe 312 is fixedly connected. On the side of the ultra-high molecular weight polyethylene bin 309, a discharge pipe 310 is fixedly connected. The feed pipe 312 extends into the supercharger 409. The sealing gasket 311 effectively prevents the leakage of the conveyed object, causing economic losses.

[0033] The top of the tank body 402 is fixedly connected to a top frame 403. On the top of the top frame 403, a stirring motor 404 is installed. The output end of the stirring motor 404 is fixedly connected to a rotating rod 405. The direct drive mode of the stirring motor 404 reduces the intermediate transmission device, simplifies the mechanical structure, and reduces the possibility of mechanical failures.

[0034] The bottom of the rotating rod 405 is fixedly connected to stirring blades 406. There are three stirring blades 406. On the top of the tank body 402, a feed pipe 407 is fixedly connected. The rotation of the stirring blades 406 can preprocess the object for more effective conveying.

[0035] In this embodiment, as Figure 1 、 Figure 4 and Figure 5 shown, the main body 1 includes a cabinet 101. On the side of the cabinet 101, an electric box 102 is fixedly connected. On the side of the electric box 102, a nameplate 106 is fixedly connected. The nameplate 106 is an important identifier of the product or equipment, which can clearly display key information such as product name, model, manufacturer, technical parameters, safety warnings, etc. These information are crucial for users to correctly use, maintain and manage the equipment, and also contribute to product quality monitoring and after-sales service.

[0036] On the side of the nameplate 106, there are a backlit button 103, a start switch 104 and a rotary doorknob 105. There are three backlit buttons 103. The backlit buttons 103 provide intuitive feedback through the lights, allowing users to clearly understand the status of the buttons. For example, the light is on when the button is pressed and off when it is released. This design enables users to quickly confirm whether the operation is successful.

[0037] On the top of the cabinet 101, a control box 107 is fixedly connected. On the side of the control box 107, a display 108 is fixedly connected. On the side of the control box 107, there are adjustment buttons 109 and an emergency stop button 110. The emergency stop button 110 can quickly trigger an alarm or request help in an emergency, greatly shortening the emergency response time.

[0038] In this embodiment, as Figure 1 and Figure 6As shown, the support moving component 2 includes a bottom plate 201. A shock-proof plate 202 is fixedly connected to the bottom of the bottom plate 201. Moving wheels 205 are provided at the bottom of the shock-proof plate 202. A hydraulic cylinder 203 is installed at the bottom of the shock-proof plate 202. The output end of the hydraulic cylinder 203 is fixedly connected to a floor footing 204. The floor footing 204 and the moving wheels 205 can be used for two-way adjustment of moving and fixing the whole device, improving the overall mobility and flexibility of the device. When the device needs to be fixed, the internal hydraulic support rod is lifted or lowered by driving the hydraulic cylinder 203, so that the floor footing 204 contacts the ground, and at this time the moving wheels 205 leave the ground, and the device can be fixed.

[0039] There are four bottom plates 201, shock-proof plates 202, hydraulic cylinders 203, floor footings 204 and moving wheels 205. The shock-proof plate 202 can effectively absorb and disperse vibration energy, reducing the damage of vibration to the device or structure. By reducing the vibration and impact received by the device during operation, the shock-proof plate 202 can significantly extend the service life of the device, reducing the failure rate and maintenance cost of the device.

[0040] The working process of the present invention: When the low-speed filter press slurry pump designed by this solution is working, during the conveying process, the object can be pre-treated. The stirring motor 404 can be driven to drive the rotating rod 405 to rotate, so that the stirring blades 406 stir the object input into the tank body 402 from the feeding pipe 407. After stirring, the electric control execution valve 410 is controlled to convey the object. When flowing into the supercharger 409, the supercharger 409 will increase the pressure of the flow rate of the object, accelerating the flow rate of the object, and thus increasing the conveying efficiency. The pressurized object will flow into the ultra-high molecular weight polyethylene bin 309 from the feeding pipe 312. The motor 302 drives the coupling rod 306 to rotate, driving the impeller 307 to rotate, so that the slurry is sucked in from the suction port and pushed towards the discharge pipe 310. Its low-speed design can effectively reduce wear, and at the same time ensure that the slurry containing solid particles will not be blocked during conveying. When the whole device needs to be moved or fixed, the floor footing 204 and the moving wheels 205 can be used for two-way adjustment of moving and fixing the whole device, improving the overall mobility and flexibility of the device. When the device needs to be fixed, the internal hydraulic support rod is lifted or lowered by driving the hydraulic cylinder 203, so that the floor footing 204 contacts the ground, and at this time the moving wheels 205 leave the ground, and thus the whole device can be fixed.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
