Description

Technical Field

[0001] This utility model belongs to the field of permeable membrane processing technology, and relates to a raw material plasticizing device for permeable membranes. Background Technology

[0002] Permeable membranes are membrane materials with special structures and functions, and are widely used in environmental protection, sewage treatment, civil engineering and other fields.

[0003] In the production process of permeable membranes, dry raw materials (such as polymer particles) need to be plasticized to transform them into a uniform molten state for subsequent molding and processing.

[0004] Traditional plasticizing equipment typically adds raw materials directly into the feeding hopper, and then the raw materials enter the extruder by their own weight for mixing, stirring, heating, and melting. However, in actual production, it is often necessary to add multiple raw materials to the extruder. Before this, the staff needs to weigh the multiple raw materials according to a certain ratio and then add them to the feeding hopper. This process needs to be done manually, which is cumbersome and inefficient. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a raw material plasticizing device for a permeable membrane that supports the weighing and feeding of multiple raw materials.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A raw material plasticizing device for a permeable membrane includes an extruder and a feeding hopper mounted on the extruder. The feeding hopper is characterized by a support plate with a vertically penetrating inlet in the center. Four support rods are arranged in a circular array on the upper edge of the support plate. Weighing and dispensing components are mounted on the inner sides of each of the four support rods, and are symmetrically arranged. Each weighing and dispensing component includes a feeding hopper, a moving mechanism, and a sealing plate. The feeding hopper is positioned above the support plate, with its lower opening above the feeding inlet. The feeding hopper is connected to the support rods. The moving mechanism is fixed to the lower part of the support rods. The sealing plate is connected to the moving mechanism and, driven by the moving mechanism, can close the lower opening of the feeding hopper or move it away from the lower opening. A weighing device is also embedded in the sealing plate.

[0008] The raw material plasticizing device for this permeable membrane provides stable support and a feeding channel for the weighing and feeding components through support plates and support rods. The weighing and feeding components weigh various raw materials and feed them into the feeding hoppers, improving upon the cumbersome and inefficient operation of traditional manual proportioning, weighing, and feeding. The four weighing and feeding components operate independently, flexibly handling different types and proportions of raw materials to meet diverse production needs. Specifically, the four sealing plates are first moved below the four feeding hoppers by a moving mechanism, closing the lower openings of the hoppers. The four weighing devices are then tare to zero. Then, according to the permeable membrane production process requirements, different raw materials are added to the feeding hoppers. The weighing devices weigh the materials in the corresponding feeding hoppers in real time. The raw materials are transported via an external conveying mechanism (such as a conveying pipe). The operation of the external conveying mechanism, the moving mechanism, and the weighing devices are all... The system can be uniformly controlled by an external control system. When a certain raw material reaches the required weight for the proportion, the feeding of that raw material is stopped, and the corresponding moving mechanism drives the corresponding sealing plate away from the corresponding feeding hopper, thereby opening the lower opening of the feeding hopper. The raw material in the feeding hopper is then fed into the feeding hopper below through the feed inlet. When a certain raw material reaches the upper limit of the feeding hopper's capacity but still does not reach the required weight for the proportion, the feeding of that raw material can be stopped and the corresponding sealing plate removed. After the raw material is completely fed from the feeding hopper into the feeding hopper, the processes of sealing, peeling, raw material feeding, weighing, opening and closing, and feeding are repeated until each raw material reaches the required amount for the proportion. This reduces the tediousness of manual operation by the staff, improves the efficiency of raw material feeding, and thus improves the overall production line efficiency. Finally, all the raw materials fed into the feeding hopper can enter the extruder for mixing, stirring, heating and melting to achieve the raw material plasticizing effect of the permeable membrane.

[0009] In the above-mentioned raw material plasticizing device for permeable membrane, the feeding hopper and the support rod are connected by a mounting frame. The mounting frame is fixed to the upper inner side of the support rod, and a vertical through-hole is provided on the mounting frame. The feeding hopper is installed at the mounting hole.

[0010] The design of the mounting bracket ensures the stable installation of the feeding hopper.

[0011] In the above-mentioned raw material plasticizing device for permeable membrane, the moving mechanism is a cylinder, which is fixedly connected to the support rod and the piston rod end of the cylinder is fixedly connected to one side of the sealing plate.

[0012] The moving mechanism uses a cylinder to drive the sealing plate to move horizontally. When the piston rod of the cylinder extends, the sealing plate can move to the bottom of the feeding hopper and close the lower opening of the feeding hopper, so that the raw material will not leak when it is fed into the feeding hopper. When the piston rod of the cylinder retracts, the sealing plate moves away from the feeding hopper, and the lower opening of the feeding hopper opens, so that the raw material in the feeding hopper can be fed into the feeding hopper under the action of gravity.

[0013] In the above-mentioned raw material plasticizing device for permeable membrane, the diameter of the mounting port is smaller than the outer diameter of the upper part of the feeding hopper, and the diameter of the mounting port is larger than the outer diameter of the lower part of the feeding hopper.

[0014] The structure of the mounting port allows the feeding hopper to be stably positioned on the mounting frame, preventing it from falling off.

[0015] In the above-mentioned raw material plasticizing device for permeable membrane, the sealing plate and the support plate are parallel to each other and have a gap.

[0016] The sealing plate does not contact the support plate, ensuring smooth movement of the sealing plate.

[0017] In the above-mentioned raw material plasticizing device for permeable membrane, there are gaps between the four feeding hoppers and between the four sealing plates.

[0018] The gaps between the four feeding hoppers and between the sealing plates prevent mutual interference and avoid affecting the weighing results.

[0019] In the above-mentioned raw material plasticizing device for permeable membrane, the upper surface of the weighing device is flush with the upper surface of the sealing plate.

[0020] The upper surface of the weighing device is flush with the upper surface of the sealing plate, making the structure more compact and ensuring that the sealing plate moves more smoothly and steadily when it moves at the lower opening of the feeding hopper.

[0021] In the above-mentioned raw material plasticizing device for permeable membrane, the projected area of ​​the lower opening of the four feeding hoppers is smaller than the projected area of ​​the feed inlet.

[0022] This design ensures that raw materials fed from the lower openings of the four feeding hoppers can smoothly enter the feeding hopper through the inlet.

[0023] Compared with existing technologies, the raw material plasticizing device of this permeable membrane weighs and feeds various raw materials into the feeding hopper through a weighing and feeding component. This improves the cumbersome operation of traditional manual proportioning, weighing and feeding, reduces manual intervention, improves work efficiency, and can flexibly cope with different types and proportions of raw material combinations to meet diverse production needs.

[0032] like Figure 1 As shown in Figure 4, the raw material plasticizing device for this permeable membrane includes an extruder 1 and a feeding hopper 2 mounted on the extruder 1. A support plate 9 is mounted on the feeding hopper 2, and a feed inlet 10 is vertically opened through the middle of the support plate 9. Four support rods 8 are arranged in a circular array on the upper edge of the support plate 9. Weighing and dispensing components are mounted on the inner side of each of the four support rods 8. The four weighing and dispensing components are symmetrically arranged in the center. Each weighing and dispensing component includes a feeding hopper 7, a moving mechanism, and a sealing plate 4. The feeding hopper 7 is mounted above the support plate 9, and the lower opening of the feeding hopper 7 is located above the feed inlet 10. The feeding hopper 7 is connected to the support rods 8. The moving mechanism is fixed to the lower part of the support rods 8. The sealing plate 4 is connected to the moving mechanism, and under the drive of the moving mechanism, the sealing plate 4 can close the lower opening of the feeding hopper or move away from the lower opening of the feeding hopper. A weighing device 11 is also embedded in the sealing plate 4.

[0033] The feeding hopper 7 is connected to the support rod 8 by a mounting frame 5. The mounting frame 5 is fixed to the upper inner side of the support rod 8. The mounting frame 5 has a vertical through-hole 6, and the feeding hopper 7 is installed at the mounting hole 6.

[0034] The moving mechanism is a cylinder 3, which is fixedly connected to the support rod 8 and the piston rod end of the cylinder 3 is fixedly connected to one side of the sealing plate 4.

[0035] The diameter of the mounting port 6 is smaller than the outer diameter of the upper part of the feeding hopper 7, and the diameter of the mounting port 6 is larger than the outer diameter of the lower part of the feeding hopper 7.

[0036] The sealing plate 4 and the support plate 9 are parallel to each other and have a gap between them.

[0037] There are gaps between the four feeding hoppers 7 and between the four sealing plates 4.

[0038] The upper surface of the weighing device 11 is flush with the upper surface of the sealing plate 4.

[0039] The projected area of ​​the lower openings of the four feeding hoppers 7 is smaller than the projected area of ​​the feed inlet 10.

[0040] The raw material plasticizing device of this permeable membrane provides stable support and a feeding channel for the weighing and feeding components through the support plate 9, support rod 8, and mounting frame 5.

Specifically, the cylinder 3 moves the four sealing plates 4 below the four feeding hoppers and closes the lower openings of the hoppers, tareing the four weighing devices 11 to zero. Then, according to the permeable membrane production process requirements, different raw materials are added to the feeding hopper 7.

The raw materials can be transported through an external conveying mechanism (such as a conveying pipe). The operation of the external conveying mechanism, cylinder 3, and weighing devices 11... All processes can be uniformly controlled by an external control system. When a certain raw material reaches the required weight for the proportion, the feeding of that raw material is stopped, and the corresponding cylinder 3 drives the corresponding sealing plate 4 away from the corresponding feeding hopper 7, thereby opening the lower opening of the feeding hopper 7. The raw material in the feeding hopper 7 is fed into the feeding hopper 2 below through the feed inlet 10. When a certain raw material reaches the upper limit of the feeding hopper 7 but still does not reach the required weight for the proportion, the feeding of that raw material can be stopped and the corresponding sealing plate 4 can be removed. After the raw material is completely fed from the feeding hopper 7 into the feeding hopper 2, the operations of sealing, peeling, raw material feeding, weighing, opening and closing, and feeding are repeated until each raw material reaches the required amount for the proportion. This reduces the tediousness of manual operation by the staff, improves the efficiency of raw material feeding, and thus improves the overall production efficiency of the production line. Finally, all the raw materials fed into the feeding hopper 2 can enter the extruder 1 for mixing, stirring and heating to melt, achieving the raw material plasticizing effect of the permeable membrane.
