Description

Technical Field

[0001] This utility model relates to the field of pulp mixing and processing technology, specifically to a dry strength agent addition device for pulp mixing and processing. Background Technology

[0002] In pulp production, dry strength agents can effectively improve paper strength. The uniformity of their addition is crucial to the quality of paper products. Traditional addition methods are mostly manual or simple mechanical feeding, which can easily lead to fluctuations in pulp performance due to uneven mixing. In addition, manual operation is inefficient and labor-intensive, making it difficult to meet the continuous and high-precision processing requirements of modern pulp production lines. Therefore, there is an urgent need for an efficient and uniform dry strength agent addition device.

[0003] The existing equipment does not have a pretreatment addition mechanism, so the agglomerates in the dry strength agent cannot be broken up. If they enter the equipment directly, they are likely to cause internal blockages, affecting normal operation. The lack of crushing and screening processes results in large differences in the particle size of the dry strength agent. Larger particles will enter the subsequent mixing process with the pulp, leading to insufficient and uneven mixing and reducing the quality of pulp processing. Utility Model Content

[0004] The purpose of this invention is to provide a dry strength agent addition device for pulp mixing and processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dry strength agent addition device for pulp mixing and processing, comprising a workbench, with support legs fixedly connected to the left and right ends of the bottom of the workbench, a placement groove opened at the center of the top of the workbench, a rotating mixing mechanism provided on the surface of the workbench, and a dry strength agent pretreatment addition mechanism provided on the surface of the workbench.

[0006] The dry strength agent pretreatment addition mechanism includes a support frame, which is fixedly connected to the rear end of the top of the workbench. A pretreatment box is fixedly connected to the top of the support frame, and a top cover is provided on the top of the pretreatment box. Crushing rollers are rotatably connected to the front and rear ends of the middle section inside the support frame. Crushing blades are fixedly connected to the surface of the crushing rollers. A crushing control motor is installed on the right side of the pretreatment box. Side seats are fixedly connected to the left and right sides of the middle section inside the pretreatment box, and filter plates are provided on the top of the side seats. A discharge pipe is fixedly connected to the bottom of the pretreatment box. Through the two sets of crushing rollers and the crushing blades on the surface, the material is crushed... Driven by a control motor, the dry strength agent is crushed, which can pulverize the clumps of dry strength agent and ensure that the dry strength agent has a uniform texture. After crushing, the dry strength agent is screened through a filter plate. Unqualified large particles are retained, while qualified particles enter the mixing tank through the discharge pipe. This ensures that the added dry strength agent particles are of appropriate size, which is conducive to subsequent mixing with pulp. The support frame provides stable support, the top cover can prevent material from splashing during crushing, and the side seats can fix the filter plate. The overall structure is easy to operate and maintain. The dry strength agent pretreatment and addition mechanism can pretreat the dry strength agent before mixing to prevent large pieces of dry strength agent from clogging the inside of the device.

[0007] Preferably, the crushing roller is fixedly connected to the left output end of the crushing control motor, and both the crushing roller and the crushing control motor are provided in two sets.

[0008] Preferably, the crushing control motor is located at the outer right end of the pretreatment box, the rotary mixing mechanism includes a mixing tank, and the discharge pipe corresponds to the mixing tank.

A first fixing sleeve is fixedly connected to the surface of the rotating shaft, and a first mixing plate is fixedly connected to the surface of the first fixing sleeve. A second... Two fixed sleeves are used, with a second stirring plate fixedly connected to the surface of the second fixed sleeve. A bottom scraper is fixedly connected to the bottom end of the second stirring plate. A servo motor drives the rotating base and the mixing tank to rotate via a rotating shaft. At the same time, the servo control motor drives the rotating shaft to rotate, so that the first and second stirring plates stir the pulp and dry strength agent. The double rotation stirring improves the mixing effect. The bottom scraper at the bottom end of the second stirring plate contacts the bottom of the mixing tank, which can scrape off the material remaining at the bottom of the tank, avoiding waste and residue affecting the next mixing. The motor frame fixes the servo motor, and the placement frame fixes the stirring frame. The triangular protrusion enhances the stability of the stirring frame and ensures that the stirring process is carried out smoothly. The setting of the rotation mixing mechanism can achieve efficient and uniform mixing.
