Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to a filter paper raw material mixing device. Background Technology

[0002] During the production of automotive filter paper, the pulp needs to be stirred and mixed. However, during stirring, pulp residue easily remains on the walls of the stirring tank. Furthermore, the pulp is heated during the stirring process, and the rising heat within the tank causes the pulp residue on the tank walls to dry rapidly, resulting in hardening and deterioration of the pulp. This leads to raw material waste, and the hardened pulp is difficult to handle. Therefore, this invention provides a filter paper raw material stirring device to solve the aforementioned problems. Utility Model Content

[0003] The purpose of this invention is to provide a filter paper raw material stirring device to overcome the above-mentioned shortcomings in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a filter paper raw material stirring device, comprising: a stirring tank, a tank top fixedly connected to the top of the stirring tank, an installation bracket provided inside the tank top, a harmonic reducer provided at the bottom of the installation bracket, the harmonic reducer including a wave generator, the wave generator being fixedly sleeved on a stirring rod, a flexible gear being sleeved on the outer side of the wave generator, a rigid gear meshing with the outer side of the flexible gear, the rigid gear being fixedly installed on the installation bracket, two connecting rods symmetrically arranged on the flexible gear, and an arc-shaped scraper that fits against the inner wall of the stirring tank being fixedly connected to the end of the connecting rod.

[0005] Furthermore, the arc-shaped scraper is provided with a sloping chute for discharging slurry into the mixing tank.

[0006] Furthermore, a stirring paddle is fixedly connected to the bottom of the stirring rod, and the stirring paddle is connected to the stirring rod in the middle by a reinforcing rod.

[0007] Furthermore, multiple turbulence-distributing rods are arranged in an array on the reinforcing rod, and a turbulence-distributing ring is fixedly connected to the upper and lower sides of each turbulence-distributing rod.

[0008] Furthermore, the spoiler rod is rhomboid in shape.

[0009] Furthermore, a motor is mounted on the top of the mounting bracket, and the output shaft of the motor is fixedly connected to the top of the stirring rod.

[0010] In the above technical solution, the filter paper raw material stirring device provided by this utility model has the following beneficial effects:

[0011] 1. By setting up a harmonic reducer, this utility model perfectly achieves rapid mixing of slurry while scraping off the slurry splashed onto the inner wall of the mixing tank at low speed. This prevents the slurry from hardening and deteriorating on the inner wall of the mixing tank, saving raw materials. At the same time, it prevents the deteriorated slurry from affecting the undeteriorated slurry in the mixing tank, thus improving the quality of the slurry.

[0012] 2. The process of mixing removes the slurry residue remaining on the inner wall of the mixing tank, reducing the difficulty of cleaning the mixing tank later and saving labor.

[0013] 3. By setting up turbulence rods, the turbulence effect during slurry mixing is increased, thereby improving the mixing efficiency. By setting up turbulence rings, the amount of air bubbles generated in the slurry is increased, further improving the mixing efficiency of the slurry.

[0014] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0024] Please see Figures 1-4 A filter paper raw material mixing device includes: a mixing tank 1, a tank top 2 fixedly connected to the top of the mixing tank 1, a mounting bracket 3 disposed inside the tank top 2, the mounting bracket 3 consisting of a central circular plate and four connecting plates, the four connecting plates being fixedly connected to the inner wall of the tank top 2, a harmonic reducer 6 disposed at the bottom of the mounting bracket 3, the harmonic reducer 6 including a wave generator 61, the wave generator 61 being fixedly sleeved on a mixing rod 4, a flexible gear 62 being sleeved on the wave generator 61, a rigid gear 63 meshing with the outer side of the flexible gear 62, the rigid gear 63 being fixedly mounted on the mounting bracket 3, two connecting rods 7 symmetrically arranged on the flexible gear 62, a connecting block 621 fixedly connected to the bottom of the flexible gear 62, the two connecting rods 7 being fixedly connected to the connecting block 621, and an arc-shaped scraper 8 fixedly connected to the end of the connecting rod 7, which fits against the inner wall of the mixing tank 1, the arc-shaped scraper 8 having a collection chute 9 for discharging slurry into the mixing tank 1. Figure 2 The material collection chute 9 is arranged at an incline. As the connecting rod 7 rotates clockwise, the arc-shaped scraper 8 scrapes along the inner wall of the mixing tank 1, scraping the slurry remaining on the inner wall of the mixing tank 1 into the material collection chute 9, and sliding into the mixing tank 1 along the inclined surface of the material collection chute 9. The wave generator 61 is equipped with a thin-walled ball flexible bearing on the outside of the elliptical ring block. The flexible gear 62 is movably sleeved on the outside of the thin-walled ball flexible bearing. The flexible gear 62 meshes with the rigid gear 63. The harmonic reducer 6 is a pre-sold product with the advantage of a large transmission ratio. Its working principle is common knowledge known to those skilled in the art.

[0025] Furthermore, a stirring paddle 41 is fixedly connected to the bottom of the stirring rod 4, and the middle part of the stirring paddle 41 is connected to the stirring rod 4 via a reinforcing rod 42. (See reference) Figure 2 One end of the reinforcing rod 42 is welded to the agitator 41, and the other end is welded to the agitator rod 4, which strengthens the agitator 41 and increases its turbulence-increasing ability.

[0026] Furthermore, multiple baffle rods 43 are arrayed on the reinforcing rod 42. Each baffle rod 43 has a baffle ring 44 fixedly connected to its upper and lower sides. The baffle rod 43 is rhomboid in shape. A motor 5 is installed on the top of the mounting bracket 3. The output shaft of the motor 5 is fixedly connected to the top of the stirring rod 4. The rhomboid shape is more conducive to cutting the slurry during the stirring process. By fixing a baffle ring 44 to each of the upper and lower ends of the baffle rod 43, the amount of air bubbles generated in the slurry is increased, further improving the stirring and mixing efficiency of the slurry.

[0027] In this utility model, reference Figures 1 to 4 A feed inlet 21 is provided on the top of the bucket 2. The feed inlet 21 is the opening for feeding raw materials and allows observation of the mixing of the slurry. First, the raw materials are fed into the mixing bucket 1 through the feed inlet 21. Then, the motor 5 is started, and the motor 5 drives the stirring rod 4 to rotate. Then, the wave generator 61, which is fixedly sleeved on the outside of the stirring rod 4, will rotate. This will drive the flexible gear 62 to rotate, so that the outer teeth of the flexible gear 62 mesh and roll along the inner teeth of the rigid gear 63. Since the number of inner teeth of the rigid gear 63 is two more than the number of outer teeth of the flexible gear 62, the wave generator 61 rotates one revolution, so that the flexible gear 62 rotates in the opposite direction at a certain angle. The specific transmission ratio can be calculated according to the harmonic gear transmission ratio formula. Then, the stirring rod 4 drives the stirring paddle 41 to rotate quickly to stir the slurry. The flexible gear 62 drives the arc-shaped scraper 8 to rotate slowly along the inner wall of the mixing bucket 1 and scrape off the residual slurry.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
