Description

Technical Field

[0001] This utility model relates to the field of material conveying pump technology, and in particular to an anti-clogging coal chemical material conveying pump. Background Technology

[0002] Coal chemical material conveying pumps are key equipment in coal chemical production used to transport various materials. They are mainly used to handle media with high temperature, high pressure, high viscosity, or containing solid particles, such as coal slurry, tar, and syngas liquid products. Coal chemical material conveying pumps have significant comprehensive advantages in coal chemical production and can adapt to complex and demanding process requirements. These pumps are manufactured using special materials such as stainless steel, high-chromium alloys, or ceramic coatings, possessing excellent corrosion resistance and wear resistance, and can stably convey media containing acidic or alkaline components, or special media such as coal slurry, tar, methanol, and dimethyl ether, over long periods.

[0003] However, in actual production, coal chemical material conveying pumps have the following defects: a large amount of metal debris is mixed in during the production of coal chemical materials. Metal debris entering the conveying pump can easily cause valve blockage, resulting in the conveying pump not working properly. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a clog-proof coal chemical material conveying pump that can filter residual metal debris before the material enters the conveying pump, thereby reducing the probability of clogging.

[0005] The purpose of this utility model is achieved by the following technical solution: a clog-proof coal chemical material conveying pump, comprising: an anti-clogging device and a pump body.

[0006] The anti-clogging device includes a feed pipe, a settling pipe, and a discharge pipe. The feed pipe, settling pipe, and discharge pipe are connected sequentially along the material conveying direction. The connection between the settling pipe and the discharge pipe is defined as a connection port. The settling pipe has a settling section pipe located below the connection port. The settling section pipe is used to contain metal impurities after settling.

[0007] The pump body's inlet is connected to the outlet side of the discharge pipe.

[0008] Furthermore, a filter screen is connected to the communication port.

[0009] Furthermore, the filter extends vertically or extends downward at an angle relative to the horizontal plane.

[0010] Furthermore, the filter screen has a ring-shaped structure and is attached to the inner wall of the settling pipe.

[0011] Furthermore, a metal impurity discharge port is provided at the bottom of the settling section pipe, and a sealing plug is detachably connected to the metal impurity discharge port.

[0012] Furthermore, the sealing plug is threadedly connected to the settling segment pipe.

[0013] Furthermore, the settling section pipe contains a magnet, which is used to attract iron filings inside the settling pipe.

[0014] Furthermore, the sealing plug has an axial blind hole that extends upward from the bottom of the sealing plug, and the magnet is disposed within the axial blind hole; the magnet has a rod-shaped structure and is attached to the inner wall of the axial blind hole.

[0015] Furthermore, the sealing plug is connected to a cap, which is capable of opening or closing the axial blind hole.

[0016] Furthermore, the sealing plug is threaded onto the cover.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. Based on the fact that the feed pipe, settling pipe, and discharge pipe are sequentially connected along the material conveying direction, it can be understood that the liquid coal chemical material enters the anti-clogging device from the feed pipe, settles metallic impurities (including but not limited to incompletely gasified or combusted coal ash and dust in the raw coal, coke particles from the coal coking or gasification process, and metal debris generated by wear of pipes, storage tanks, or transportation equipment) through the settling pipe, and is then discharged through the discharge pipe. The pipeline structure is easily adaptable to the pump body, maintaining the required high-pressure environment during transportation and ensuring sealing.

[0019] 2. Based on the definition that the connection between the settling pipe and the discharge pipe is a communication port, the settling pipe has a settling section pipe located below the communication port. It can be understood that, according to the physical properties of coal chemical materials and coke particles, the density of metallic impurities is greater than that of liquid coal chemical materials. Therefore, relying on gravity, the metallic impurities can sink to the bottom of the settling section pipe. This design method has two advantages over the traditional simple addition of a filter screen: First, the filtration effect can be achieved through the pipe's own structure. Second, it can avoid the corrosion of the filter screen by coal chemical materials under long-term operating conditions, which would cause the filter screen to lose its filtration function and thus require frequent replacement, saving costs.

[0020] 3. Based on the connection between the pump body's inlet and the outlet side of the discharge pipe; it is understood that, in order to stably transport coal chemical materials, the pump body should not be frequently disassembled. Therefore, from the perspective of material transportation, the anti-clogging device is placed before the pump body to intercept metal impurities before they enter the pump body, preventing the accumulation of metal impurities from causing blockages in valves or internal pipes. Furthermore, removing metal impurities outside the pump body can also prevent sharp metal impurities from scratching the internal components of the pump body. Attached Figure Description

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] like Figure 1 As shown, a preferred embodiment of the present invention provides an anti-clogging coal chemical material conveying pump, comprising: an anti-clogging device 1 and a pump body 2.

[0029] The anti-clogging device 1 includes a feed pipe 11, a settling pipe 12, and a discharge pipe 13. The feed pipe 11, the settling pipe 12, and the discharge pipe 13 are connected sequentially along the material conveying direction. The connection between the settling pipe 12 and the discharge pipe 13 is defined as a connection port 14. The settling pipe 12 has a settling section pipe 121 located below the connection port 14. The settling section pipe 121 is used to accommodate metal impurities after settling.

[0030] The inlet 21 of the pump body 2 is connected to the outlet side 131 of the discharge pipe 13.

[0031] Based on the fact that the feed pipe 11, settling pipe 12, and discharge pipe 13 are sequentially connected along the material conveying direction, it can be understood that the liquid coal chemical material enters the anti-clogging device 1 from the feed pipe 11, settles metallic impurities (including but not limited to incompletely gasified or combusted coal ash and dust in the raw coal, coke particles from the coal coking or gasification process, and metal debris generated by wear of pipes, storage tanks, or transportation equipment) through the settling pipe 12, and is then discharged through the discharge pipe 13. The pipeline structure is easily adaptable to the pump body 2, which can maintain the required high-pressure environment during transportation and ensure sealing.

[0032] Based on the definition that the connection between the settling pipe 12 and the discharge pipe 13 is a connecting port 14, the settling pipe 12 has a settling section pipe 121 located below the connecting port 14. It can be understood that, according to the physical properties of coal chemical materials and coke particles, the density of metallic impurities is greater than that of liquid coal chemical materials. Therefore, relying on gravity, the metallic impurities can sink to the bottom of the settling section pipe 121. Compared to the traditional method of adding a filter screen 15, this design achieves the filtration effect solely through the pipe's own structure. Furthermore, since coal chemical materials contain acidic substances such as sulfides, they are inherently corrosive. The filter screen 15 is generally made of stainless steel, which is prone to rusting over long-term operation. Therefore, the design using the settling section pipe 121 also avoids frequent replacement of the filter screen 15, saving costs.

[0033] Since the inlet 21 of the pump body 2 is connected to the outlet 131 of the discharge pipe 13, it is understood that the pump body 2 should not be frequently disassembled in order to stably transport coal chemical materials. Therefore, from the perspective of material transportation, the anti-clogging device 1 is placed in front of the pump body 2 to intercept metal impurities before they enter the pump body 2, thus preventing the accumulation of metal impurities from causing blockages in valves or internal pipes. In addition, removing metal impurities from the pump body 2 can also prevent sharp metal impurities from scratching the internal components of the pump body 2.

[0034] like Figure 2 As shown in Figure 3, preferably, the connecting port 14 is connected to a filter screen 15. It can be understood that coal chemical materials are viscous, and gravity sedimentation can generally only screen out larger particulate impurities. Smaller impurities or dust can still be carried by the coal chemical materials and pass through the anti-clogging device 1. Therefore, adding a filter screen 15 can play a secondary filtration role and improve the overall filtration effect.

[0035] like Figure 3 As shown, preferably, the filter 15 extends vertically or extends downwards at an angle relative to the horizontal plane. It can be understood that the settling pipe 12 has a settling section pipe 121. Since the settling section pipe 121 utilizes the principle of gravity settling, it implies that the settling section pipe 121 extends vertically downwards or downwards at an angle relative to the horizontal plane. Therefore, it can be concluded that the filter 15 extends along the downward direction of the settling pipe 12, allowing the particles intercepted by the filter 15 to settle within the settling section pipe 121.

[0036] like Figure 3 As shown, preferably, the filter screen 15 has a ring-shaped structure and is attached to the inner wall of the settling pipe 12. It can be understood that the ring-shaped filter screen 15 has a larger interception area. The purpose of attaching the filter screen 15 to the inner wall of the settling pipe 12 is to stabilize the filter screen 15 and prevent it from shaking due to the impact of coal chemical materials, thus affecting the filtration effect.

[0037] like Figure 3 As shown, preferably, the bottom of the settling section pipe 121 is provided with a metal impurity discharge port 122, and the metal impurity discharge port 122 is detachably connected to a sealing plug 16. It can be understood that setting the metal impurity discharge port 122 facilitates the periodic discharge of metal impurities. When discharge is required, the sealing plug 16 can be opened to allow the metal impurities to be discharged without disassembling the entire anti-clogging device 1, simplifying the daily maintenance process.

[0038] like Figure 3 As shown, preferably, the sealing plug 16 is threadedly connected to the settlement segment pipe 121. It is understood that threaded connections offer both flexibility and reliable sealing, and can effectively prevent leakage when used with sealant, PTFE tape, or gaskets. This is suitable for operating conditions requiring periodic disassembly and reassembly.

[0039] like Figure 3 As shown, preferably, the settling section pipe 121 houses a magnet 17, which is used to adsorb iron filings inside the settling pipe 12. It can be understood that the magnet 17 provides a three-stage filtration effect after gravity settling in the settling section pipe 121 and interception by the filter screen 15.

[0040] like Figure 3 As shown, preferably, the sealing plug 16 has an axial blind hole 161 extending upward from the bottom of the sealing plug 16, and the magnet 17 is disposed within the axial blind hole 161; the magnet 17 has a rod-shaped structure and fits against the inner wall of the axial blind hole 161. It can be understood that the magnet 17 can be integrally connected to the axial blind hole 161, or it can be inserted into the axial blind hole 161. Regardless of the connection method, during use, as long as the magnet 17 is pulled out, some of the attracted iron filings will be pulled out along with the magnet 17, and the remaining iron filings, no longer attracted by the magnet 17, will settle due to gravity and be discharged from the metal impurity discharge port.

[0041] like Figure 3 As shown, preferably, the sealing plug 16 is connected to a cover 18, which can open or close the axial blind hole 161. It can be understood that if the magnet 17 is movably inserted into the axial blind hole 161, it is easy to fall off due to gravity. Therefore, the purpose of providing the cover 18 is to seal the anti-clogging device 1 and provide support for the magnet 17.

[0042] like Figure 3 As shown, preferably, the sealing plug 16 is threaded to the cover 18. It is understood that the threaded connection facilitates unscrewing or tightening the cover 18.

[0043] It should be noted that the anti-clogging device 1 is mainly composed of pipe segments, and therefore can be adapted to various pump bodies 2 that require pipe connections.

[0044] In summary, the working principle of this utility model is as follows: Coal chemical materials enter the anti-clogging device 1 from the feed pipe 11, and flow towards the settling pipe 12 based on their own fluidity and the pressure difference inside and outside the pipe. When the coal chemical materials enter the settling pipe 12, they first sink to the settling section pipe 121 due to gravity, and then flow towards the connection port. During this process, larger metal impurities will settle to the settling section pipe 121 due to their higher density, while iron filings are attracted by the magnet 17; smaller metal impurities or dust are blocked by the filter screen 15. After separating the metal impurities from the coal chemical materials through three different methods, the filtered coal chemical materials are finally discharged from the discharge pipe 13 and flow to the pump body 2, and then transported to other places by the pump body 2. When it is necessary to discharge metal impurities, first empty the coal chemical materials in the pipeline, then unscrew the cover 18, pull out the magnet 17 from the axial blind hole 161, unscrew the sealing plug 16, and the separated metal impurities can be discharged from the metal impurity discharge port 122. After the discharge is completed, put the sealing plug 16, magnet 17 and cover 18 back in sequence.
