Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of material conveying equipment, and relates to a self-cleaning conveying device for high solids materials. Background Technology
[0002] The conveying of high-solids materials has always been a technical challenge in industrial production, especially when the material contains a high percentage of solid particles, which can easily cause blockages at the inlet filter of the conveying pump. Traditional conveying devices have revealed significant technical defects in actual operation: as the conveying time increases, solid particles gradually accumulate on the filter surface, forming a dense blockage layer. This not only significantly increases the pump's suction resistance, leading to a sharp decrease in conveying efficiency, but also causes a series of chain reactions such as increased equipment vibration and energy consumption. In severe cases, it can even cause cavitation damage to the pump.
[0003] The manual cleaning methods commonly used in the industry have many drawbacks. Operators need to frequently stop the machine to disassemble the filter screen for mechanical cleaning. This intermittent maintenance method not only increases labor intensity and maintenance costs, but also seriously affects the continuous operation of the production line, leading to a decrease in overall production efficiency. Especially in fields such as chemical and mining industries, where high production continuity is required, this method is no longer sufficient to meet the needs of modern production. Although some simple backwashing designs exist in existing technologies, they often suffer from insufficient flushing pressure and unreasonable flushing angles, failing to effectively remove highly adhesive blockages. Furthermore, high-pressure flushing can easily damage the filter screen structure. In addition, there is a lack of adaptive adjustment methods for high-solids materials with different physical properties (such as viscosity and particle size distribution), resulting in poor versatility of existing equipment. Utility Model Content
[0004] The purpose of this invention is to solve the problems in the prior art and provide a self-cleaning conveying device for high solids materials, which realizes self-cleaning and stable operation of the entire process of conveying high solids materials.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] This utility model provides a self-cleaning conveying device for high-solids materials, comprising:
[0007] The high-solids raw material feeding line is connected to the underground high-solids storage tank;
[0008] The high solids-liquid submersible pump has an inlet end connected to a pump inlet pipeline extending into the underground high solids storage tank, and an outlet end connected to a pump outlet pipeline.
[0009] A filter is installed at the inlet of the pump inlet pipeline;
[0010] An ultrasonic transducer is disposed on the pump inlet pipeline and arranged adjacent to the filter;
[0011] The backwash line has its inlet end connected to the main flush water pipe and its outlet end connected to the pump outlet pipe.
[0012] Preferably, the underground high-solids storage tank is equipped with a stirrer.
[0013] Preferably, the agitator is fixedly installed via an agitator fixing point located on the inner wall of the bottom of the underground high-solids storage tank.
[0014] Preferably, the underground high-solids storage tank is equipped with a steam tracing system; the inlet end of the steam tracing system is connected to the steam supply pipeline, and the outlet end is connected to the steam return pipeline.
[0015] Preferably, the main flushing water pipe is connected to the underground high-solids storage tank via a flushing line, and a first valve is installed on the flushing line.
[0016] Preferably, a second valve is provided on the backwash line.
[0017] Preferably, a third valve is provided on the pump outlet pipeline, and the third valve is located near the outlet end of the pump outlet pipeline.
[0018] Preferably, it also includes a disturbance line; the inlet end of the disturbance line is connected to the pump outlet pipeline, and the outlet end is connected to the high solids raw material feed line; a fourth valve is provided on the disturbance line.

[0020] Preferably, the pump outlet pipeline is equipped with a local pressure gauge, a remote pressure gauge, and a remote flow meter at its outlet end.
[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] The ultrasonic transducer generates high-frequency mechanical vibration waves that act directly on the vicinity of the filter, causing solid particles attached to the filter screen to vibrate slightly and fall off, thus achieving continuous cleaning and maintenance of the filter. The backwashing system establishes a reverse flow path and automatically activates when filter blockage is detected. It uses high-pressure water to backwash the filter screen, effectively removing stubborn blockages that are difficult for ultrasonic waves to handle. This invention avoids traditional manual disassembly and cleaning methods, significantly reducing maintenance costs and ensuring continuous and stable operation of the production process. It is particularly suitable for industrial conveying scenarios involving high-solids-content, easily clogged materials.
[0023] Furthermore, the agitator installed inside the storage tank ensures uniform mixing of materials through continuous operation, preventing solid sedimentation; the steam heating system maintains optimal material flowability through precise temperature control, preventing pipeline blockage; in addition, the perturbation line enhances material flowability at the filter, effectively preventing local blockage.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings:
[0034] This utility model provides a self-cleaning conveying device for high-solids materials, such as... Figure 1 As shown, it includes:
[0035] The high-solids raw material feeding line 1 is connected to the underground high-solids storage tank 14;
[0036] The high solids submersible pump 2 has an inlet end connected to a pump inlet pipeline extending into the underground high solids storage tank 14, and an outlet end connected to a pump outlet pipeline 3.
[0037] Filter 6 is installed at the inlet of the pump inlet pipeline;
[0038] An ultrasonic transducer 5 is disposed on the pump inlet pipeline and arranged adjacent to the filter 6;
[0039] The backwash line 12 has its inlet end connected to the main flush water pipe 11 and its outlet end connected to the pump outlet pipe 3.
[0040] This utility model's high-solids material self-cleaning conveying device integrates an ultrasonic cleaning and backwashing system, achieving efficient self-cleaning and continuous operation in the high-solids material conveying process. A filter 6 is installed at the inlet of the high-solids submersible pump 2 to filter large particulate impurities in the high-solids material. An ultrasonic transducer 5 is arranged adjacent to the filter 6, utilizing high-frequency vibration to effectively prevent solid particles from accumulating on the filter screen surface, significantly reducing the risk of clogging. Flushing water enters the pump outlet pipeline 3 from the flushing water main pipe 11 via the backwash line 12 and flows backward into the filter 6 to flush it. The flushed wastewater enters the underground high-solids storage tank 14. The connection between the backwash line 12 and the flushing water main pipe 11 forms a reverse flushing mechanism, allowing the filter 6 to be flushed backward without disassembling the equipment, effectively removing stubborn deposits.
[0041] The underground high-solids storage tank 14 is equipped with an agitator 7, which prevents high-solids materials from settling inside the tank, ensuring material uniformity and facilitating stable material transport. The agitator 7 is fixedly installed via agitator fixing point 8 on the bottom inner wall of the underground high-solids storage tank 14, protecting the agitator's main shaft. Furthermore, the agitator 7 should only be activated when the liquid level in the underground high-solids storage tank 14 reaches at least 20% to prevent damage to the equipment due to insufficient material in the tank and the agitator operating without load.
[0042] The underground high-solids storage tank 14 is equipped with a steam tracing system. The inlet of the steam tracing system is connected to the steam supply pipeline 9, and the outlet is connected to the steam return pipeline 10. The steam tracing system continuously heats the material inside the underground high-solids storage tank 14 to prevent the high-solids material from solidifying due to temperature drop, which would affect material conveying and improve material flowability.
[0043] The main flushing water pipe 11 is connected to the underground high-solids storage tank 14 via a flushing line 13, and a first valve is installed on the flushing line 13. When diluting the material in the underground high-solids storage tank 14, or when repairing the underground high-solids storage tank 14, the main flushing water pipe 11 is opened, and the first valve on the flushing line 13 is opened to flush and replace the underground high-solids storage tank 14.
[0044] The backwash line 12 is equipped with a second valve, which controls the start and stop of the backwashing process or the disturbance process by opening and closing it.
[0045] The device of this utility model also includes a disturbance line 4; the inlet end of the disturbance line 4 is connected to the pump outlet pipeline 3, and the outlet end is connected to the high solids raw material feed line 1; a fourth valve is provided on the disturbance line 4.
[0046] A third valve is installed on the pump outlet pipeline 3, and the third valve is located near the outlet end of the pump outlet pipeline 3. The third valve is opened to transport high-solids materials. When the disturbance line 4 disturbs the flow, the third valve is closed to prevent water from being discharged from the outlet end of the pump outlet pipeline 3. The water flow is introduced into the high-solids raw material feed line 1 through the disturbance line 4, thereby forming a local circulation flow at the filter 6, which effectively solves the problem of high-solids material deposition at the pump inlet.
[0047] A fifth valve is provided on the high-solids raw material feed line 1, and the fifth valve is located near the inlet end of the high-solids raw material feed line 1 to realize the start and stop of material conveying.
[0048] The pump outlet pipeline 3 is equipped with a local pressure gauge, a remote pressure gauge, and a remote flow meter at its outlet end, which can monitor the pumping operation of the pump 2 under high solid-liquid conditions in real time, thereby determining whether the filter 6 is clogged.
[0049] The working process of this utility model is as follows:
[0050] Open the fifth valve on the high solids feed line 1 to introduce the high solids material into the underground high solids storage tank 14. Before introducing the material, confirm that the steam tracing system is in operation and close the fourth valve on the disturbance line 4. When the liquid level reaches 20%, start the upper agitator 7 to stir the high solids material in the storage tank to prevent material sedimentation. Start the high solids submersible pump 2 and open the third valve on the pump outlet pipeline 3 to transport the high solids material to the next section.
[0051] When the high-solids submersible pump 2 malfunctions, it is determined that filter 6 is clogged. The ultrasonic transducer 5 is activated first to clean filter 6. If this is ineffective, the agitation line 4 is activated. After confirming that the fifth valve on the high-solids raw material feed line 1 is closed, the fourth valve on the agitation line 4 is opened, with the valve opening on the agitation line 4 appropriately adjusted, to agitate the material at filter 6. If the treatment effect is still insufficient, the backwash line 12 is activated. Before activation, the high-solids submersible pump 2 must be stopped, the third valve on the pump outlet pipeline 3 closed, and the fourth valve on the agitation line 4 closed to prevent flushing water from directly entering the underground high-solids storage tank 14 via the agitation line 4, affecting the flushing effect. Then, the second valves on the flushing water main pipe 11 and the backwash line 12 are opened to backwash filter 6 through the backwash line 12, clearing the blockage inside filter 6. After cleaning, the flushing water main pipe 11 is closed, the second valve on the backwash line 12 is closed, the high-solids submersible pump 2 is started, and the third valve on the pump outlet pipeline 3 is opened to continue transporting high-solids materials.
[0052] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
