Polyacrylamide refining screen

Abstract

This application discloses a polyacrylamide refining and screening machine, belonging to the field of screening machines. It includes a base frame, with a storage box slidably mounted on the inner wall of the base frame. One end of a force spring is fixedly connected to the top of the base frame, and the other end of the force spring is fixedly connected to a connecting frame. A screening chamber is fixedly connected to the outer side of the connecting frame. A screening plate is fixedly mounted on the inner wall of the screening chamber, and a positioning seat is fixedly mounted at the bottom of the screening chamber. Two vibration motors are symmetrically mounted at the bottom of the positioning seat. By driving the two vibration motors to operate synchronously, the vibration force is transmitted to the screening chamber and the screening plate, accelerating the screening efficiency of the material at the top of the screening plate. Simultaneously, the elastic force of the force spring increases the amplitude of the screening plate during vibration, avoiding damage to parts and overall device wobbling caused by rigid connections. It also prevents interference with the positioning frame and the discharge chamber, further accelerating the screening efficiency.

Description

Technical Field

[0001] This application relates to the field of screening machine technology, and in particular to a polyacrylamide refining screening machine. Background Technology

[0002] Polyacrylamide is a linear polymer that is a hard, glassy solid at room temperature. Products include liquids, latexes, white powders, translucent beads, and flakes, exhibiting good thermal stability. It is soluble in water in any proportion, forming a homogeneous and transparent aqueous solution.

[0003] Existing screening machines typically incorporate vibration mechanisms to accelerate screening efficiency. However, the vibration force transmitted by these mechanisms is distributed throughout the entire screening process, potentially affecting the stability of the entire device during placement. To address this issue, this application proposes a polyacrylamide refining screening machine. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a polyacrylamide fine screening machine, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a polyacrylamide refining and screening machine, including a base frame, a storage box slidably installed on the inner wall of the base frame, one end of a force spring fixedly connected to the top of the base frame, a connecting frame fixedly connected to the other end of the force spring, a screening chamber fixedly connected to the outer side of the connecting frame, a screening plate fixedly installed on the inner wall of the screening chamber, a positioning seat fixedly installed at the bottom of the screening chamber, two vibration motors symmetrically installed at the bottom of the positioning seat, a positioning frame installed on the outer side of the base frame, a feeding bin fixedly installed on the inner wall of the positioning frame, a separation component installed on the inner wall of the feeding bin, and a protective component installed on the inner wall of the feeding bin.

[0006] In a preferred embodiment, a side frame is fixedly installed on the outer side of the base frame, and the number of force springs and connecting frames is four, with the four force springs and connecting frames symmetrically arranged on the top of the base frame and the outer side of the screening chamber.

[0007] By adopting the above technical solution, the two vibrating motors can transmit the vibration force to the screening bin and screening plate during operation. In turn, the elastic force of the force spring can be used to increase the amplitude of the screening plate during vibration, and the damage to parts caused by rigid connection can be avoided, thereby further accelerating the screening efficiency.

[0008] In a preferred embodiment, the separation assembly includes a motor, the power output shaft of which is fixedly connected to one end of a rotating rod, the other end of which is rotatably connected to the inner wall of the feeding hopper, and a plurality of separation rods are fixedly installed on the outer edge of the rotating rod.

[0009] By adopting the above technical solution, the drive motor can drive the rotating rod and the separating rod to rotate, thereby knocking the material inside the feeding hopper, which can be used to separate materials that are stuck together and ensure the efficiency of screening.

[0010] In a preferred embodiment, the protective component includes a sliding plate that is slidably connected to the inner wall of the feeding hopper. A slot is provided through the top of the sliding plate. A stud is fixedly installed on the outer side of the positioning frame. The stud is inserted into the inner wall of the slot, and a nut is threaded onto the outer edge of the stud.

[0011] By adopting the above technical solution, the interior of the feeding bin can be protected by a sliding plate, ensuring that foreign objects will not enter when it is not in use. The sliding plate moves along the inner wall of the feeding bin, which can be used to adjust the opening of the feeding bin and thus control the amount of material fed.

[0012] In a preferred embodiment, a rotating rod is fixedly installed on the outer edge of the nut, and the bottom of the nut abuts against the top of the slot.

[0013] By adopting the above technical solution, the user can improve the convenience of turning the nut by using the rotating rod, ensuring that the nut can be used to lock the slide in the correct position and prevent it from moving easily.

[0014] In a preferred embodiment, the bottom of the screening plate is connected to a discharge port, which is inclined.

[0015] By adopting the above technical solution, materials that are screened by the screening plate but do not enter the storage box can be discharged through the discharge port into an external storage container for collection.

[0016] In a preferred embodiment, the outlet of the feeding hopper is located above the screening plate, which is made of stainless steel.

[0017] By adopting the above technical solution, the material inside the feeding hopper can be directly added to the inner wall of the screening hopper and screened by the screening plate. The screening plate will not easily rust after long-term use.

[0018] The beneficial effects of this application are:

[0019] This polyacrylamide refining screening machine drives two vibration motors to operate synchronously, thereby transmitting the vibration force to the screening bin and screening plate, accelerating the screening efficiency of the material at the top of the screening plate. At the same time, it can increase the amplitude of the screening plate during vibration by utilizing the elastic force of the force spring, and can avoid damage to parts and shaking of the overall device caused by rigid connection. It will not interfere with the positioning frame and the discharge bin, further accelerating the screening efficiency.

[0020] This polyacrylamide fine screening machine uses a drive motor to rotate the rotating rod and the separating rod, which in turn can knock the material inside the feeding hopper, thereby separating materials that are stuck together and ensuring screening efficiency.

Detailed Implementation

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] Reference Figure 1-5 The polyacrylamide refining and screening machine includes a base frame 1, a storage box 2 slidably installed on the inner wall of the base frame 1, one end of a force spring 4 fixedly connected to the top of the base frame 1, a connecting frame 5 fixedly connected to the other end of the force spring 4, a screening chamber 6 fixedly connected to the outer side of the connecting frame 5, a screening plate 7 fixedly installed on the inner wall of the screening chamber 6, a positioning seat 9 fixedly installed at the bottom of the screening chamber 6, two vibration motors 10 symmetrically installed at the bottom of the positioning seat 9, a positioning frame 11 installed on the outer side of the base frame 1, a feeding hopper 12 fixedly installed on the inner wall of the positioning frame 11, a separation component installed on the inner wall of the feeding hopper 12, and a protective component installed on the inner wall of the feeding hopper 12.

[0029] See Figure 1 and Figure 3A side frame 3 is fixedly installed on the outside of the base frame 1. There are four force springs 4 and connecting frames 5. The four force springs 4 and connecting frames 5 are symmetrically arranged on the top of the base frame 1 and the outside of the screening chamber 6. This allows the two vibration motors 10 to transmit the vibration force to the screening chamber 6 and the screening plate 7 during operation. In turn, the elastic force of the force springs 4 can be used to increase the amplitude of the screening plate 7 during vibration, and can avoid damage to parts caused by rigid connection, thereby further accelerating the screening efficiency.

[0030] See Figure 1 and Figure 2 The separation assembly includes a motor 13, with one end of a rotating rod 14 fixedly connected to the power output shaft of the motor 13. The other end of the rotating rod 14 is rotatably connected to the inner wall of the feeding bin 12. Multiple separation rods 15 are fixedly installed on the outer edge of the rotating rod 14, so that the motor 13 can drive the rotating rod 14 and the separation rods 15 to rotate, thereby knocking the material inside the feeding bin 12, which can be used to separate the materials that are stuck together, ensuring the efficiency of screening.

[0031] See Figure 1 and Figure 2 The protective component includes a sliding plate 16, which is slidably connected to the inner wall of the feeding bin 12. A slot 17 is provided through the top of the sliding plate 16. A stud 18 is fixedly installed on the outer side of the positioning frame 11. The stud 18 is inserted into the inner wall of the slot 17. A nut 19 is threadedly connected to the outer edge of the stud 18, so that the sliding plate 16 can be used to protect the inside of the feeding bin 12, ensuring that foreign objects will not enter when it is not in use. The sliding plate 16 can move along the inner wall of the feeding bin 12 to adjust the opening of the feeding bin 12, thereby controlling the amount of material fed.

[0032] See Figure 2 A rotating rod 20 is fixedly installed on the outer edge of the nut 19. The bottom of the nut 19 abuts against the top of the slot 17, which makes it easier for the user to turn the nut 19 by using the rotating rod 20. This ensures that the nut 19 can be used to lock the slide plate 16 in a locked position and prevent it from moving easily.

[0033] See Figure 3 The bottom of the screening plate 7 is connected to the discharge port 8, which is set at an angle so that the material that is screened by the screening plate 7 but does not enter the storage box 2 can be discharged into the external storage container through the discharge port 8 for collection.

[0034] See Figure 1 - Figure 3The outlet of the feeding hopper 12 is located above the screening plate 7, which is made of stainless steel. This allows the material inside the feeding hopper 12 to be directly added to the inner wall of the screening hopper 6 and screened by the screening plate 7. Furthermore, the screening plate 7 will not easily rust after long-term use.

[0035] Working principle: First, materials are added to the inner wall of the screening chamber 6 through the feeding hopper 12 and screened by the screening plate 7. When materials are fed into the feeding hopper 12, the motor 13 drives the rotating rod 14 and the separating rod 15 to rotate, which in turn knocks the materials inside the feeding hopper 12, thus separating materials that are stuck together and ensuring screening efficiency. At the same time, two vibration motors 10 can be driven to work synchronously, thus transmitting the vibration force to the screening chamber 6 and the screening plate 7, accelerating the screening efficiency of the materials at the top of the screening plate 7. At the same time, the elastic force of the force spring 4 can be used to increase the amplitude of the vibration of the screening plate 7 and avoid damage to parts caused by rigid connection, further accelerating the screening efficiency. The screened materials enter the inside of the collection box 2 and are discharged into the external collection container through the discharge port 8 for collection.
