Description

Technical Field

[0001] The present application is applied to the technical field of dredging mud treatment, and in particular relates to an anti-blocking device and a pump. Background Art

[0002] When dredging mud is pumped, mud that is not stirred evenly or has settled for a period of time is relatively viscous and has lumps. These lumps can easily cause blockage when entering the suction port, affecting the normal operation of the pump and affecting the flow rate; and lumps that exceed the pump's allowable pumping particle size will damage the pump body. In some production lines, it is often necessary to mix several different fluids in a certain proportion, and the pumping flow rate needs to be controlled more accurately. If lumps enter the suction port and cause blockage, the mixing ratio of various fluids will deviate significantly from the preset value, resulting in the output of unqualified products.

[0029] The embodiment of the present application provides an anti-blocking device, see Figure 1 、 Figure 2 and Figure 3 ,include

[0030] A feeding port is provided at the top of the feeding barrel 100 and a discharge pipe 110 is provided at the side of the feeding barrel 100;

[0031] The cylindrical screen 200 is arranged close to the inner circumference of the discharge barrel 100;

[0032] The rotating mechanism 300 is connected to the cylindrical screen 200 to drive the cylindrical screen 200 to rotate relative to the discharge barrel 100.

[0033] The anti-blocking device is provided with a cylindrical screen 200 on the inner periphery of the discharge barrel 100, so the liquid to be discharged from the discharge pipe 110 needs to be screened through the cylindrical screen 200, that is, the cylindrical screen 200 can separate the viscous mud that has not been stirred evenly or has settled after a period of time from the discharge pipe 110, ensuring that the mud entering the next process will not become sticky or agglomerated. The cylindrical screen 200 can control the particle size of the discharged mud. At the same time, the rotating mechanism 300 can drive the cylindrical screen 200 to rotate relative to the discharge barrel 100. , achieving the stirring effect on the mud, and reducing the viscosity or agglomeration of the mud in the discharge barrel 100, realizing the functions of screening and anti-blocking, and improving the qualified rate of products produced in subsequent processes. The overall structure of the anti-blocking device is convenient for disassembly and maintenance, and is arranged at the pump suction port of the pump body. The rotating mechanism 300 solves the problem that after the cylindrical screen 200 has worked for a certain period of time, the cylindrical screen 200 absorbs a large amount of mud blocks under the action of pump suction to block the screen holes, resulting in a significant decrease in flow rate, and prevents mud blocks from entering the pump body to cause blockage and pump body damage.

[0034] In some embodiments, a mud pool 400 is provided at the top of the discharge barrel 100, and the mud pool 400 is used to store dredged silt. A discharge port adapted to the feed port is provided at the bottom of the discharge barrel 100, and the top of the discharge barrel 100 is connected to the mud pool 400 through the discharge port. In some embodiments, the top of the cylindrical screen 200 extends into the mud pool 400 to prevent blocky or viscous mud from entering the discharge barrel 100.

[0035] In some embodiments, a scraper 410 is fixedly connected to the mud pool 400, and the scraper 410 abuts against the inner side of the cylindrical screen 200 to scrape off the mud lumps accumulated on the cylindrical screen 200. Specifically, the scraper 410 is a silicone scraper, which allows the mud that meets the particle size to be quickly screened out through the cylindrical screen 200. The silicone scraper has good flexibility and elasticity and can adapt to the inner surface of the cylindrical screen 200; it is resistant to high temperatures, not easy to deform, resistant to chemical corrosion, has good wear resistance, and a long service life; the surface is smooth and not easy to scratch the cylindrical screen 200; it is easy to clean and maintain, and the mud on the scraper 410 is easy to remove.

[0036] In some embodiments, a holder 420 for mounting a scraper 410 is provided on the inner bottom surface of the mud pool 400. The scraper is fixed on the holder 420. The scraper 410 fits tightly against the cylindrical screen 200. When the cylindrical screen 200 rotates, the mud blocks on the cylindrical screen 200 are cleaned off by the scraper. It can be understood that the holder 420 can also be mounted on the discharge barrel 100. The holder 420 is provided to facilitate the disassembly of the scraper 410. The scraper 410 can be lifted upward for disassembly and can be replaced without emptying the mud pool 400. The holder 420 ensures that the scraper is firmly installed and is not easy to loosen or fall off, so that the scraper maintains the correct angle and position, thereby improving the scraping effect. The holder 420 facilitates the replacement of the scraper, saving time and energy. It can also protect the scraper, reduce the risk of damage to the scraper, increase the stability of the scraper, and make it more reliable during use.

[0037] It can be understood that the cylindrical screen 200 has a certain length below the pump suction port. Since the scraper will scrape off the lumpy or coagulated mud inside the cylindrical screen 200, it will block the discharge pipe 110. The cylindrical screen 200 has a certain length below the pump suction port and can store a certain amount of cleaned sediment mud blocks to avoid obstructing the discharge when mud is deposited in the discharge barrel 100. When the anti-blocking device is shut down for maintenance and overhaul, the scraper 410, cylindrical screen 200, etc. can be taken out upward for cleaning and replacement.

[0038] In some embodiments, the cylindrical screen 200 includes a first screen 210 arranged along the inner circumference of the lower barrel 100 and a second screen 220 arranged along the inner bottom surface of the lower barrel 100. The outer circumference of the second screen 220 is connected to the bottom of the first screen 210. It can be understood that the first screen 210 and the second screen 220 can be integrally formed. The integral forming makes the overall structural strength of the cylindrical screen 200 higher and more durable; and improves the overall stability of the cylindrical screen 200, reduces the shaking and deformation of the cylindrical screen 200 during use, and improves the stability of screening. Qualitative; the integrated cylindrical screen 200 is easy to install, saving installation time and cost; the connection between the first screen 210 and the second screen 220 is tight, which improves the sealing and reduces material leakage; the one-piece cylindrical screen 200 has a good screening effect, can better ensure the accuracy and uniformity of screening, and improve product quality; and the one-piece cylindrical screen 200 has strong wear resistance and extends its service life. The one-piece design makes cleaning easier, maintains the cleanliness of the cylindrical screen 200, and makes the overall appearance of the cylindrical screen 200 more tidy and beautiful.

[0039] In some embodiments, the rotating mechanism 300 includes a driven component 310 installed at the bottom of the second screen 220. The second screen 220 is annular, and the inner periphery of the second screen 220 is connected to the outer periphery of the driven component 310. The driven component 310 is arranged at the bottom of the second screen 220, so that the cylindrical screen 200 can be easily lifted up and replaced. The driven component 310 is arranged at the center position of the second screen 220 and can be replaced without emptying the mud pool 400.

[0040] The cam 320 of the embodiment of the present invention is a cam 321 that is mounted on the support frame 310 and is convenient to use and can be installed in an unobstructed manner.

[0041] In some embodiments, the rotating mechanism 300 includes a motor 330. The drive wheel of the motor 330 is connected to the rotating wheel 320 via a transmission belt 340. The cylindrical screen 200 is rotated by the motor 330. The cylindrical screen 200 at the pump suction port is always the cleaner portion after being cleaned by the scraper 410. This ensures that the flow area at the pump suction port remains relatively constant, thereby ensuring that the amount of fluid sucked into the pump is relatively stable. The transmission belt 340 has good flexibility: it can adapt to the transmission requirements of the spacing and angle between the drive wheel of the motor 330 and the rotating wheel 320. The transmission belt 340 also reduces vibration and noise during operation, providing a relatively smooth transmission effect. The transmission belt 340 can provide overload protection. When the load is too large, the belt will slip, thereby providing a certain degree of overload protection. The use of the transmission belt 340 does not require lubrication, reducing maintenance costs and environmental pollution. The transmission belt 340 is easy to install and disassemble, and does not require complex tools and techniques. Compared with other transmission methods, the transmission belt is relatively low in cost and has high transmission efficiency.

[0042] In some embodiments, the assembly gap between the cylindrical screen 200 and the inner circumference of the lower barrel 100 is smaller than the mesh size of the cylindrical screen 200, preventing the mud from being discharged directly from the discharge pipe 110 through the gap between the cylindrical screen 200 and the inner wall of the lower barrel 100.

[0043] The present application also provides a pump, comprising a pump body 500 and the anti-blocking device of the above embodiment. The pump body 500 is provided with a pump suction port 510, which is connected to the discharge pipe 110 through the pump suction port 510. This prevents sticky or agglomerated mud from entering the pump body 500, reduces the wear and damage of unqualified mud on the pump impeller, seals and other components, ensures the stable operation of the pump, reduces the failure rate, maintains the normal flow rate of the pump, improves work efficiency, reduces the maintenance workload of the pump, extends the service life of the pump, reduces the cost of repairing and replacing parts of the pump body due to blockage, ensures the normal operation of the entire pumping system, improves system performance, and avoids safety issues such as overload and overheating of the pump body due to blockage. The anti-blocking device of the present application facilitates cleaning and maintenance and maintains the effectiveness of the pump body.

[0044] In some embodiments, the discharge pipe 110 is trumpet-shaped, that is, the discharge pipe 100 near the discharge barrel 100 has a larger diameter, and the discharge pipe 100 near the pump suction port 510 has a smaller diameter. A transport pipe is provided between the discharge pipe 100 and the pump suction port 510 of the pump body 500 to ensure that the flow area at the pump suction port 510 will not drop below the pipe flow area of the transport pipe due to the screen, and the shape of the trumpet mouth helps to discharge the mud quickly. Compared with other shapes, it is less likely to cause mud blockage, helps to disperse the material more evenly at the outlet, reduces the resistance of the material during the discharging process, and makes the discharging process more stable and reliable; it is suitable for mud of different properties and particle sizes, and can also reduce the noise generated when the material is discharged to a certain extent.
