Description

Technical Field

[0001] This application relates to the field of material conveying technology, and in particular to a material conveying device and system. Background Technology

[0002] Due to their excellent and specific adsorption properties, resins are widely used in environmental protection, metallurgy, chemical industry, pharmaceutical industry and other industries. Typically, resins are filled into packed devices (such as metal adsorption towers) and adapted to suitable adsorption processes to achieve adsorption functions.

[0003] Currently, there are several common methods for filling resin into packing devices: First, a vacuum pump is used in conjunction with a conveying pipeline to pressurize the resin and then transport it upwards. However, due to the high water content of the resin and the limited conveying head of the vacuum pump, it is not suitable for resin conveying, and the resin is prone to clogging the conveying pipeline during the conveying process. Second, a screw feeder is used in conjunction with a conveying pipeline to squeeze the resin upwards. However, during the resin conveying process, the squeezing by the screw feeder will cause resin damage, greatly reducing the resin's specific adsorption capacity and resulting in a significant reduction in the resin's adsorption effect. Third, the resin is conveyed upwards using the frictional force generated by the conveyor belt. Since the packing device is usually installed at a horizontal elevation of more than 5 meters, and the conveying height of the conveyor belt is limited, it is impossible to smoothly transport the resin to the packing device installed at a higher elevation. Summary of the Invention

[0004] Therefore, it is necessary to provide a material conveying device and system to address the problem that the existing resin conveying devices have limited conveying height, which may greatly reduce the resin adsorption capacity.

[0005] A conveying device, disposed in a filling device, the conveying device comprising:

[0006] The material rack includes a housing and a cavity formed inside the housing. The housing has a feeding port, a liquid inlet and a discharging port communicating with the cavity. The feeding port is used to feed solid raw materials, the liquid inlet is used to input liquid media, and the discharging port is used to output solid-liquid mixtures.

[0007] At least one stirring element, which is rotatably disposed on the housing and located inside the cavity;

[0008] A conveying pipeline, one end of which is connected to the outlet and the other end of which is connected to the packing device, and the conveying pipeline is equipped with a diaphragm pump.

[0009] In one embodiment, there are multiple stirring elements, which are spaced apart along the circumferential direction of the housing, and all of the stirring elements are rotatably connected to the housing.

[0010] In one embodiment, the feed rack further includes a rotating shaft rotatably connected to the housing, and the plurality of stirring components are all connected to the rotating shaft.

[0011] In one embodiment, the diaphragm pump is located on the side of the feed line near the outlet.

[0012] In one embodiment, the feeding device further includes a return water pipeline, one end of which is connected to the packing device and the other end of which is connected to the liquid inlet.

[0013] In one embodiment, the feed line is connected to the top side of the packing device, and the return line is connected to the bottom side of the packing device.

[0014] In one embodiment, the return water pipeline has a water inlet / drain outlet, and the water inlet / drain outlet is located on the side of the return water pipeline closer to the liquid inlet.

[0015] In one embodiment, the feed port is located on the top side of the housing.

[0016] In one embodiment, the rack further includes multiple legs, all of which are disposed on the housing and spaced apart along the circumferential direction of the housing.

[0017] A material conveying system, the material conveying system comprising:

[0018] Packing devices; and

[0019] The conveying device as described in any of the above technical solutions is connected to the packing device and is used to convey the solid-liquid mixture to the packing device.

[0020] In the aforementioned conveying device and system, when a solid-liquid mixture needs to be conveyed to the packing device, solid raw materials are fed into the chamber through the feeding port, and liquid medium is introduced into the chamber through the liquid inlet. Hydraulic impact causes the agitator to rotate relative to the shell, ensuring thorough mixing of the solid raw materials and liquid medium to form a solid-liquid mixture. This mixture is then discharged through the discharge port to the conveying pipeline, and after being powered by a diaphragm pump, it is conveyed to the packing device. In this conveying device, the rotating agitator provides the conveying pressure for the solid-liquid mixture. The increased hydraulic effect of the rotating agitator, combined with the diaphragm pump, increases the conveying height of the solid-liquid mixture. Furthermore, hydraulic conveying prevents the solid-liquid mixture from clogging the conveying pipeline during transport and avoids squeezing the mixture, maintaining its excellent specific adsorption properties.

[0035] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0036] See Figure 1 and Figure 2As shown, this application provides a conveying device 100, which includes a material rack 110, at least one agitator 120, and a conveying pipeline 130. The conveying device 100 is disposed in a packing device 200 to convey a solid-liquid mixture to the packing device 200. In this application, the solid-liquid mixture is a mixture of resin particles and water, and the packing device 200 is an adsorption tower. The conveying device 100 can convey the solid-liquid mixture to the packing device 200 for adsorption treatment of waste gas, etc.

[0037] The material rack 110 includes a housing 111, inside which a chamber 112 is formed. The housing 111 has a feeding port 1111, a liquid inlet 1112, and a discharge port 1113. The feeding port 1111 is used to feed solid raw materials (such as resin particles), and the feeding port 1111 is connected to the chamber 112. If the housing 111 has an open structure, the feeding port 1111 is formed at the open end of the housing 111, so that solid raw materials can be fed into the chamber 112 through the feeding port 1111. Preferably, the feeding port 1111 is located on the top side of the housing 111, so that when solid raw materials are fed into the chamber 112, the solid raw materials can move towards the bottom side of the housing 111 under the action of gravity, avoiding the accumulation of solid raw materials in the feeding port 1111 and clogging the feeding port 1111, thus improving the smoothness of solid raw material feeding. The inlet 1112 is used to input a liquid medium (such as water), and is connected to the chamber 112 to input the liquid medium into the chamber 112. The liquid medium input through the inlet 1112 is a high-pressure liquid medium. The outlet 1113 is used to output a solid-liquid mixture, and is connected to the chamber 112. After the solid raw material and the liquid medium mix in the chamber 112 to form a solid-liquid mixture, the mixture can be output through the outlet 1113.

[0038] The agitator 120 is rotatably mounted on the housing 111 and located inside the chamber 112. When a liquid medium is introduced into the chamber 112, the hydraulic force generated by the liquid medium impacts the agitator 120, causing it to rotate relative to the housing 111. This rotation of the agitator 120 mixes the solid raw materials and liquid medium inside the chamber 112. Furthermore, by controlling the flow rate and speed of the liquid medium, the rotation speed of the agitator 120 can be adjusted, thereby adjusting the mixing effect between the solid raw materials and the liquid medium. Preferably, the agitator 120 has a plate structure to increase the contact area between the agitator 120 and the liquid medium. This increases the hydraulic force exerted by the liquid medium on the agitator 120, ensuring smooth rotation of the agitator 120 under hydraulic impact. The plate structure of the agitator 120 also improves the mixing effect between the solid raw materials and the liquid medium. Of course, in other feasible embodiments, the stirring element 120 may also be a rod-shaped structure or other types of structures. This application does not limit the specific structure of the stirring element 120.

[0039] One end of the conveying pipeline 130 is connected to the outlet 1113, and the other end of the conveying pipeline 130 is connected to the packing device 200. The conveying pipeline 130 is equipped with a diaphragm pump 140. Specifically, when a solid-liquid mixture needs to be conveyed to the packing device 200, the solid raw material is fed into the chamber 112 through the feed port 1111, and the liquid medium is fed into the chamber 112 through the liquid inlet 1112. The hydraulic impact causes the stirring element 120 to rotate relative to the shell 111, so that the solid raw material and the liquid medium are fully mixed to form a solid-liquid mixture. The solid-liquid mixture is output to the conveying pipeline 130 through the outlet 1113, and after being powered by the diaphragm pump 140, it is conveyed to the packing device 200. Preferably, the conveying pipeline 130 is detachably connected to the packing device 200 by means of screwing, snap-fit, or other methods. This allows the conveying device 100 to be connected to a designated packing device 200 for conveying solid-liquid mixtures, or the conveying device 100 to be detached from the connected packing device 200, making it easy to reconnect the conveying device 100 to another packing device 200 for conveying solid-liquid mixtures, thereby improving the ease of operation and applicability of the conveying device 100.

[0040] The aforementioned conveying device 100, with its agitator 120 providing conveying pressure for the solid-liquid mixture during rotation, and the increased hydraulic effect of the agitator 120 in conjunction with the diaphragm pump 140, can increase the conveying height of the solid-liquid mixture. This satisfies the conveying device 100's requirements for conveying solid-liquid mixtures to the packing device 200, which is installed at a higher position. Furthermore, the hydraulic conveying prevents the solid-liquid mixture from clogging the conveying pipeline 130 during transport and avoids squeezing the solid-liquid mixture, thus maintaining its good specific adsorption properties. By automating the conveying operation of the solid-liquid mixture through the conveying device 100, the conveying efficiency of the solid-liquid mixture is improved, and the conveying intensity of the solid-liquid mixture is reduced.

[0041] In one embodiment, see Figure 1 and Figure 2 As shown, there are multiple agitators 120, which are spaced apart along the circumferential direction of the housing 111 and are rotatably connected to the housing 111. When the liquid medium generates hydraulic impact on the agitators 120, all agitators 120 can rotate relative to the housing 111, further improving the mixing effect of the agitators 120 on the solid raw materials and liquid medium inside the chamber 112. The synchronous rotation of multiple agitators 120 can further increase the hydraulic effect generated by the liquid medium, providing a greater conveying pressure to increase the conveying height of the solid-liquid mixture.

[0042] Further, see Figure 1 and Figure 2 As shown, the material rack 110 also includes a rotating shaft 113, which is rotatably connected to the housing 111. In this embodiment, the rotating shaft 113 and the housing 111 are sealed and fixedly connected by a bushing to avoid gaps between the rotating shaft 113 and the housing 111, thereby preventing leakage of the liquid medium. Multiple stirring elements 120 are connected to the rotating shaft 113. For example, if there are three stirring elements 120, the angle formed between two adjacent stirring elements 120 and the axis of the rotating shaft 113 is 120°; if there are four stirring elements 120, the angle formed between two adjacent stirring elements 120 and the axis of the rotating shaft 113 is 90°; for other numbers of stirring elements 120, the angle formed between two adjacent stirring elements 120 and the axis of the rotating shaft 113 changes adaptively, which will not be described in detail here. Thus, when a liquid medium is introduced into the chamber 112, the liquid medium generates a hydraulic impact on the agitator 120. Since the agitator 120 is connected to the rotating shaft 113, the rotating shaft 113 rotates relative to the housing 111 and drives the agitator 120 to move accordingly. The agitator 120 stirs and mixes the solid raw materials and liquid medium inside the chamber 112.

[0043] In one embodiment, see Figure 1 and Figure 2As shown, the diaphragm pump 140 is positioned on the side of the conveying pipeline 130 near the outlet 1113. When the solid-liquid mixture is initially discharged through the outlet 1113 into the conveying pipeline 130, the diaphragm pump 140 provides power for conveying the mixture within the pipeline 130. The rotation of the diaphragm pump 140, in conjunction with the agitator 120, increases the conveying height of the solid-liquid mixture. Furthermore, positioning the diaphragm pump 140 near the outlet 1113 of the conveying pipeline 130 prevents the solid-liquid mixture from flowing back into the chamber 112 due to insufficient conveying height under hydraulic pressure, thus avoiding the undesirable situation of the mixture not being successfully conveyed to the packing device 200.

[0044] If a solid-liquid mixture is conveyed to the packing device 200, the mixture is sieved through a high-mesh screen within the packing device 200, allowing the solid material to remain within the packing device 200 to complete the adsorption treatment of waste gas, etc., while some of the liquid medium needs to be discharged from the packing device 200. Based on this, in one embodiment, see... Figure 1 and Figure 2 As shown, the conveying device 100 also includes a return water pipe 150, one end of which is connected to the packing device 200, and the other end of which is connected to the liquid inlet 1112. When the solid-liquid mixture is conveyed to the packing device 200, the solid-liquid mixture is screened by a high-mesh screen inside the packing device 200, separating the solid raw material from part of the liquid medium. The solid raw material remains in the packing device 200 to perform adsorption treatment of waste gas, etc., while the part of the liquid medium separated from the solid raw material after being screened by the high-mesh screen flows back to the chamber 112 through the return water pipe 150 to participate in the mixing of solid raw materials and generate hydraulic action, thereby realizing the recycling of the liquid medium. Preferably, the return water pipe 150 is detachably connected to the packing device 200 by means of screwing, snap-fit, etc. Since the conveying pipe 130 is also detachably connected to the packing device 200, the conveying device 100 can be connected to a designated packing device 200 for conveying solid-liquid mixtures and partial liquid medium return operations, or the conveying device 100 can be disassembled from the connected packing device 200 to facilitate the reconnection of the conveying device 100 to another packing device 200 for conveying solid-liquid mixtures and partial liquid medium return operations, thereby further improving the ease of operation and applicability of the conveying device 100.

[0045] Further, see Figure 1 and Figure 2As shown, the conveying pipeline 130 is connected to the side of the packing device 200 near the top, so that after the solid-liquid mixture is conveyed to the packing device 200, the solid-liquid mixture can move towards the bottom of the packing device 200 under the action of gravity, avoiding the solid-liquid mixture from accumulating at the connection between the conveying pipeline 130 and the packing device 200 and clogging the conveying pipeline 130, thus improving the smoothness of the solid-liquid mixture conveying. Since some liquid medium will accumulate at the bottom of the packing device 200 under the action of gravity after separating from the solid raw materials, the return water pipeline 150 is connected to the side of the packing device 200 near the bottom. The return water pipeline 150 can guide the liquid medium accumulated at the bottom of the packing device 200 to the inside of the shell 111 to re-participate in the mixing of solid raw materials and generate hydraulic action, so as to realize the recycling of liquid medium.

[0046] Furthermore, see Figure 1 and Figure 2 As shown, the return water pipeline 150 has a water inlet / outlet 151, which is located on the side of the return water pipeline 150 closest to the liquid inlet 1112. Since there is a risk of contamination of the liquid medium during long-term mixing, the liquid medium returned to the conveying device 100 by the packing device 200 can be discharged through the water inlet / outlet 151, and the liquid medium can be replaced. Regular replacement of the liquid medium ensures its cleanliness and maintains the good specific adsorption properties of the solid-liquid mixture. Furthermore, when the hydraulic pressure of the liquid medium input into the chamber 112 through the liquid inlet 1112 is insufficient, the liquid medium can be supplemented into the chamber 112 through the water inlet / outlet 151, thereby increasing the hydraulic pressure of the liquid medium and meeting the height requirements of hydraulic conveying of solid-liquid mixtures.

[0047] In one embodiment, see Figure 2 and Figure 3 As shown, the material rack 110 also includes multiple support legs 114. These support legs 114 are all attached to the housing 111 by welding, screwing, or other methods, and are spaced apart along the circumferential direction of the housing 111 to support the material rack 110 and ensure its stable placement on the work platform (such as the mounting ground). For example, there may be three support legs 114 spaced apart along the circumferential direction of the housing 111, or four support legs 114 spaced apart along the circumferential direction of the housing 111. It should be noted that, due to the stability of a triangle, the number of support legs 114 in this application is at least three. However, this application does not limit the specific number of support legs 114.

[0048] Additionally, see Figure 1 and Figure 2As shown, this application also provides a material conveying system 300, which includes a packing device 200 and a material conveying device 100 as described above. The material conveying device 100 is connected to the packing device 200 and is used to convey a solid-liquid mixture to the packing device 200. The solid-liquid mixture can be conveyed to the packing device 200 through the material conveying device 100 for adsorption treatment of waste gas, etc.

[0049] The aforementioned conveying system 300, with its agitator 120 providing conveying pressure for the solid-liquid mixture during rotation, and the increased hydraulic effect of the liquid medium during rotation of the agitator 120, combined with the diaphragm pump 140, can increase the conveying height of the solid-liquid mixture. This satisfies the conveying device 100's requirements for conveying solid-liquid mixtures to the packing device 200, which is installed at a higher position. Furthermore, hydraulic conveying prevents the solid-liquid mixture from clogging the conveying pipeline 130 during conveying and also prevents it from being squeezed, maintaining the good specific adsorption properties of the solid-liquid mixture. By automating the conveying operation of the solid-liquid mixture through the conveying system 300, the conveying efficiency of the solid-liquid mixture is improved, and the conveying intensity of the solid-liquid mixture is reduced.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
