Description

Technical Field

[0001] The utility model belongs to the technical field of polyacrylamide production equipment, and particularly relates to a feeding device for preparing alkali-resistant polyacrylamide. Background Technique

[0002] Polyacrylamide is a linear high molecular polymer with the chemical formula. It is a hard glassy solid at room temperature, and the products include glue solution, latex, white powder, translucent beads, flakes, etc.; during the production process of polyacrylamide, a blowing device is required for feeding.

[0003] Since the feeding port of the conventional blowing device is blocked in front of the positive air outlet, the eddy current formed by the wind pressure is likely to backflow into the feeding port, which is likely to form a large amount of dust, and it is relatively difficult to disassemble and clean inside, resulting in a relatively low practicality of the conventional blowing device for preparing alkali-resistant polyacrylamide.

[0004] Therefore, we propose a feeding device for preparing alkali-resistant polyacrylamide to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem of relatively low practicality of the conventional blowing device for preparing alkali-resistant polyacrylamide, and to propose a feeding device for preparing alkali-resistant polyacrylamide.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A feeding device for preparing alkali-resistant polyacrylamide includes a fan. A wind guide cylinder is fixedly connected to the lower part of the fan. An air collecting hood is arranged on the side of the wind guide cylinder. Screws are inserted between the air collecting hood and the wind guide cylinder. A feeding pipe is fixedly connected to the outside of the air collecting hood. A support is fixedly connected to the lower end of the air collecting hood. A feeding hopper is fixedly connected to the upper part of the air collecting hood. The interior of the feeding hopper is communicated with the interior space of the air collecting hood. Connect the working power supply of the fan to make the air flow blow to the front of the air collecting hood through the wind guide cylinder, preventing the air flow from pouring into the feeding hopper, so that part of the air flow is sucked into the air collecting hood from the outside of the air collecting hood and the inside of the feeding hopper; pour the material into the feeding hopper and introduce it into the air collecting hood through the feeding hopper, preventing the material from being blown out when feeding the hopper. Remove the screws and remove the wind guide cylinder for cleaning, improving the practicality.

[0008] Preferably, a first reinforcing rod is fixedly connected to the lower part of the support. The first reinforcing rod is used to increase the stability of the lower structure of the support.

[0009] Preferably, a second reinforcing rod is fixedly connected to the front part of the support. The second reinforcing rod is used to increase the stability of the upper structure of the support.

[0010] Preferably, the air collecting hood includes an air collecting shell, an outer shell, and a first mounting ear. The air collecting shell is fixedly connected to the outer shell as a whole, and the internal spaces of the air collecting shell and the outer shell are interconnected. The first mounting ears are uniformly and fixedly connected to the outside of the outer shell. The air flow is sent into the air collecting shell through the air guiding tube by a fan. The air guiding tube blocks the lower side of the feeding hopper, which helps prevent the air flow from flowing back into the feeding hopper.

[0011] Preferably, the air guiding tube includes a mounting seat, a cylinder body, a connecting plate, and a second mounting ear. The connecting plate is fixedly connected to the inner wall of the mounting seat. The cylinder body is fixedly connected between the two connecting plates. The second mounting ear is fixedly connected to the outer periphery of the mounting seat. When the gas from the fan is blown out, it enters the cylinder body and is discharged into the air collecting shell through the cylinder body, forming a negative pressure on the outer periphery of the cylinder body. As a result, part of the gas is sucked into the air collecting shell from the tail of the mounting seat and inside the feeding hopper, which helps guide the materials entering the outer shell into the air collecting shell and send them into the material guiding tube.

[0012] Preferably, the feeding hopper includes a hopper body and a feeding pipe. The lower end of the hopper body is fixedly connected to the upper end of the feeding pipe. The materials are poured into the hopper body and guided into the feeding pipe through the hopper body, and then sent to the outside of the cylinder body through the feeding pipe, which facilitates feeding materials into the outer shell.

[0013] In summary, the technical effects and advantages of the present utility model are as follows:

[0014] 1. Connect the working power supply of the fan to make the air flow blow to the front of the air collecting hood through the air guiding tube, preventing the air flow from pouring into the feeding hopper, and enabling part of the air flow to be sucked into the air collecting hood from the outside of the air collecting hood and inside the feeding hopper; pour the materials into the feeding hopper, guide the materials into the air collecting hood through the feeding hopper, prevent the materials from being blown out during feeding of the feeding hopper, remove the screws, and remove the air guiding tube for cleaning, which improves the practicability.

[0015] 2. The air flow is sent into the air collecting shell through the air guiding tube by the fan. The air guiding tube blocks the lower side of the feeding hopper, which helps prevent the air flow from flowing back into the feeding hopper.

[0016] 3. When the gas from the fan is blown out, it enters the cylinder body and is discharged into the air collecting shell through the cylinder body, forming a negative pressure on the outer periphery of the cylinder body. As a result, part of the gas is sucked into the air collecting shell from the tail of the mounting seat and inside the feeding hopper, which helps guide the materials entering the outer shell into the air collecting shell and send them into the material guiding tube.
