Description

Technical Field

[0001] This invention relates to the field of pulp preparation technology, specifically to an automatic integrated pulp raw material mixing device. Background Technology

[0002] Pulp molding is a three-dimensional papermaking technology. It uses waste paper as raw material, shaping it into specific paper products using special molds on a molding machine. The pulp used in paper box tableware is a primary product of the pulp molding industry. Pulp is a fibrous material made from plant fibers through various processing methods. It is the basic raw material for papermaking. Paper mills use waste paper as raw material, breaking it down and mixing it with water to initially form pulp. The production process of pulp requires paper material crushing equipment. The pulp crushing and beating process involves feeding large sheets of paper into a crushing device and grinding them to obtain finished pulp. The quality of the pulp determines the quality of the molded paper products. Mixing equipment is needed to continuously stir the raw pulp, ensuring a more uniform dilution and mixing of fibers, water, and other chemical raw materials.

[0003] Existing pulp mixing equipment generally uses large mixing tanks for mixing. A common pulp mixing tank includes a tank body, a rotating shaft, and blades. A drive motor is installed on the tank body, and the rotating shaft is vertically mounted on the tank body. The shaft of the drive motor is coaxially fixed to the rotating shaft, and multiple blades are fixedly mounted on the rotating shaft. During mixing, pulp and various chemical raw materials are transported into the tank body together. The drive motor is turned on, and the blades stir the pulp. After mixing for a period of time, the desired pulp is obtained.

[0004] Under the above technical conditions, stirring a large amount of slurry takes a particularly long time, and the mixing effect of pulp and other chemical raw materials is poor, resulting in a slow production efficiency.

[0005] Based on this, the present invention designs an automatic integrated pulp raw material mixing device to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic integrated pulp raw material mixing device to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automatic integrated pulp raw material mixing device, comprising a tank, a premixing tank, a diversion plate, and a drive motor. The premixing tank is fixedly connected to the tank body. An mounting plate, which is an annular plate, is fixedly installed inside the premixing tank. The diversion plate is fixedly installed on the mounting plate. A first feed pipe is fixedly installed between the diversion plate and the side wall of the premixing tank. The first feed pipe is horizontally positioned. A first nozzle is fixedly installed at the outlet of the feed pipe, facing the side wall of the premixing tank. A diversion plate is fixedly installed between the diversion plate and the side wall of the premixing tank. The container is equipped with a second feed pipe. The outlets of the first and second feed pipes are positioned opposite each other. A second nozzle is fixedly installed on the outlet of the second feed pipe, facing the side wall of the premixing tank. A drain outlet is provided on the guide plate. A connection port is provided on the premixing tank, communicating with the tank body. A drive motor is fixedly installed on the premixing tank. A stirring shaft is coaxially fixed on the shaft of the drive motor. The stirring shaft passes through the connection port, with one end of the stirring shaft located inside the tank body. The water sprayed from the first and second nozzles is in contact with each other.

[0008] By adopting the above technical solution, during the stirring process, the liquid entering through the first feed pipe and the second feed pipe comes into contact and collides with each other, allowing the liquid to be pre-mixed before falling into the tank for stirring, thereby greatly shortening the stirring time and improving production efficiency.

[0009] Preferably, multiple feed pipes are arranged vertically on the first feed plate, and the multiple feed pipes are simultaneously fixedly connected to the same first nozzle.

[0010] By adopting the above technical solution, when the liquid enters the nozzle from multiple first feed pipes, the liquid undergoes pre-collision and mixing in the nozzle, thereby improving the mixing effect of the liquid.

[0011] Preferably, multiple vertically arranged first feed pipes are arranged as a group, and two groups of first feed pipes are arranged on the separation plate, with the water outlet directions of the two groups of first feed pipes being opposite.

[0012] By adopting the above technical solution, the two sets of first discharge pipes discharge material simultaneously, further improving the mixing efficiency.

[0013] Preferably, a lower guide plate and an upper guide plate are fixedly provided on the inner side wall of the premix tank.

[0014] By adopting the above technical solution, the upper guide plate and the lower guide plate can guide the liquid material, allowing it to flow towards the center, thereby improving the effect of mixing the liquid material.

[0015] Preferably, a dispersing plate is fixedly installed in the tank, the dispersing plate is inclined, and multiple dispersing plates are arranged in the vertical direction, with the lower side of the dispersing plate located above the higher side of the adjacent lower dispersing plate.

[0016] By adopting the above technical solution, when the liquid falls from the outlet onto the dispersing plate, the dispersing plate can further disperse the liquid and improve the mixing effect.

[0017] Preferably, a manifold is fixedly mounted on the mounting plate, and a clearance opening is provided on the manifold, through which the stirring shaft passes.

[0018] By adopting the above technical solution, the mixed liquid flowing out of the outlet falls onto the manifold plate for further contact and mixing.

[0019] Preferably, a stirring blade is fixedly disposed on the stirring shaft, and the stirring blade is located in the relief opening.

[0020] By adopting the above technical solution, when the liquid passes through the discharge port, the stirring plate further disperses the stirring plate, thereby improving the mixing effect.

[0021] In summary, this application has the following beneficial technical effects: during stirring, the liquid entering through the first feed pipe and the second feed pipe comes into contact and collides with each other, allowing the liquid to be pre-mixed before falling into the tank for stirring, thereby greatly shortening the stirring time and achieving the effect of improving production efficiency.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] An automatic integrated pulp raw material mixing device includes a tank body 1, a premixing tank 2, a diversion plate 3, and a drive motor 4. The premixing tank 2 is fixedly connected to the tank body 1, and an mounting plate 5, which is annular, is fixedly installed inside the premixing tank 2. The diversion plate 3 is also annular and is fixedly installed on the mounting plate 5. A first feed pipe 6 is fixedly installed between the diversion plate 3 and the side wall of the premixing tank 2. The first feed pipe 6 is horizontally arranged, and a first nozzle 7 is fixedly installed on the outlet of the feed pipe. Multiple first feed pipes 6 are arranged vertically on the diversion plate 3. In this embodiment, three feed pipes are arranged. Multiple feed pipes are simultaneously fixedly connected to the same first nozzle 7, and the nozzle faces the side wall of the premixing tank 2.

[0033] A second feed pipe 8 is fixedly installed between the diversion plate 3 and the side wall of the premix tank 2. The outlets of the first feed pipe 6 and the second feed pipe 8 are positioned opposite each other. A second nozzle 10 is fixedly installed on the outlet of the second feed pipe 8. Multiple second feed pipes 8 are arranged vertically on the diversion plate 3. In this embodiment, three second feed pipes 8 are provided. The multiple second feed pipes 8 are fixedly connected to the second nozzles 10, which face the side wall of the premix tank 2. One end of the first feed pipe 6 is connected to a water pump, while one end of the second feed pipe 8 is fixedly connected to a different water pump. Both the first nozzle 7 and the second nozzle 10 are duckbill-shaped nozzles.

[0034] The guide plate 3 has a drain outlet 11, and the premix tank 2 has a connection port 12, which communicates with the tank body 1. The drive motor 4 is fixedly mounted on the premix tank 2, and a stirring shaft 13 is coaxially fixed on the shaft of the drive motor 4. The stirring shaft 13 passes through the connection port 12, and one end of the stirring shaft 13 is located in the tank body 1. During stirring, various raw material slurries can be fed into different first feed pipes 6 or second feed pipes 8. For example, if there are four raw materials, two raw materials can be fed into two different first feed pipes 6, and the remaining two raw materials can be fed into two different second feed pipes 8.

[0035] Turn on the drive motor 4 to rotate the stirring shaft 13, which in turn stirs the mixture. This drives the water pump, and the liquid ejected by the first nozzle 7 flows along the side wall of the premix tank 2 under high pressure. At the same time, the liquid ejected by the second nozzle 10 also flows along the side wall of the premix tank 2 under high pressure. Finally, the water ejected by the first nozzle 7 and the water ejected by the second nozzle 10 collide and come into contact. Under the strong impact and collision, the raw materials are broken apart and mixed together. The mixed liquid flows into the tank 1 through the drain outlet 11 for stirring, which greatly shortens the stirring time and improves production efficiency.

[0036] Three first feed pipes 6 form a group, with two groups of first feed pipes 6 arranged on the separation plate. The water outlet directions of the two groups of first feed pipes 6 are opposite. Similarly, two groups of second feed pipes 8 are also arranged. During premixing, the two groups of first feed pipes 6 and the two groups of second feed pipes 8 spray water simultaneously, which can further improve the premixing efficiency and reduce the premixing time. There are two water outlets. One water outlet is located between the corresponding first nozzle 7 and second nozzle 10, and the other water outlet is located between another corresponding first nozzle 7 and second nozzle 10. Multiple first feed pipes 6 are fixedly connected to the first nozzle 7. When the liquid enters the first nozzle 7, the liquid on both sides can be squeezed and mixed towards the liquid in the middle, so that the liquid begins to be initially mixed before it exits the first nozzle 7.

[0037] A lower guide plate 15 and an upper guide plate 14 are fixedly installed on the inner side wall of the premixing tank 2. The upper guide plate 14 and the lower guide plate 15 are inclined, with the lower end of the upper guide plate 14 located above the higher end of the lower guide plate 15. Multiple upper guide plates 14 and lower guide plates 15 are installed on the premixing tank 2. When the water flow ejected from the first nozzle 7 flows along the side wall of the premixing tank 2, the upper guide plate 14 can guide the liquid on the upper side to flow towards the liquid in the middle, while the lower guide plate 15 can guide the liquid on the lower side to flow towards the liquid in the middle, so that the liquid ejected from multiple first feed pipes 6 is mixed again after being ejected from the nozzle, thereby improving the mixing effect of the raw materials.

[0038] A manifold 16 is fixedly mounted on the mounting plate 5. The manifold 16 has a clearance port 17. The stirring shaft 13 passes through the clearance port 17, and the mixed liquid flowing from the two outlets falls onto the manifold 16 to re-merge, allowing the liquid to further contact and mix thoroughly. A stirring blade 18 is fixedly mounted on the stirring shaft 13, located within the clearance port 17. As the mixed liquid passes through the clearance port 17, the stirring blade 18 disperses the liquid, further improving the mixing effect between the liquids.

[0039] A dispersing plate 9 is fixedly installed in the tank body 1. The dispersing plate 9 is inclined and multiple dispersing plates 9 are arranged in the vertical direction. The lower side of the dispersing plate 9 is located above the higher side of the adjacent dispersing plate 9 below. When the liquid falls from the relief port 17, it falls onto the dispersing plate 9. The dispersing plate 9 can disperse the liquid again. After being dispersed by multiple dispersing plates 9, the multiple liquids are more fully mixed, thereby further improving the mixing effect.

[0040] The implementation principle of this embodiment is as follows: the water pump is driven, and the liquid ejected by the first nozzle 7 under high pressure flows along the side wall of the premixing tank 2. At the same time, the liquid ejected by the second nozzle 10 under high pressure also flows along the side wall of the premixing tank 2. Finally, the water ejected by the first nozzle 7 and the water ejected by the second nozzle 10 collide and come into contact. Under the strong impact and collision, the raw materials are broken apart and mixed together. The mixed liquid flows into the tank 1 through the drain outlet 11 for stirring, which greatly shortens the stirring time and achieves the effect of improving production efficiency.
