Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically a raw material mixing device for the production of citric acid disinfectant. Background Technology

[0002] Citric acid disinfectant is a disinfectant made by scientifically mixing and formulating citric acid and malic acid as the main active ingredients, supplemented with synergists, corrosion inhibitors and other additives. Currently, the production of citric acid disinfectant requires adding various raw materials into a mixing tank for mixing. Solid raw materials such as citric acid need to be dissolved in liquid solvent raw materials.

[0003] However, existing mixing devices mainly consist of mixing containers and simple stirring mechanisms. When large solid citric acid raw materials are added to the solvent and stirred until dissolved, there is a long waiting time. Furthermore, the initial water absorption and clumping of solid raw materials upon contact with the solvent results in low mixing and dissolution efficiency. In addition, undissolved solid particles settle to the bottom of the solvent, making it difficult to stir evenly. Therefore, a raw material mixing device for the production of citric acid disinfectant is needed to solve the problems existing in the prior art. Utility Model Content

[0004] The purpose of this invention is to provide a raw material mixing device for the production of citric acid disinfectant, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material mixing device for the production of citric acid disinfectant, comprising a raw material mixing cylinder, a stirring shaft rotatably connected inside the raw material mixing cylinder, a horizontal stirring rod provided on the lower part of the side surface of the stirring shaft, a grinding mechanism provided inside the raw material mixing cylinder, the grinding mechanism comprising a reciprocating grinding funnel and a receiving bucket fixed on the stirring shaft, the grinding funnel being slidably connected inside the raw material mixing cylinder, the receiving bucket being rotatably connected inside the raw material mixing cylinder, and a leakage hole being provided on the inner wall of the receiving bucket.

[0006] Preferably, a feeding pipe is fixed to the upper end face of the grinding hopper, and a lifting screw sleeve is fixed to the inner wall of the feeding pipe.

[0007] Preferably, the middle section of the side surface of the stirring shaft is provided with a reciprocating screw section, which is threadedly connected to the lifting screw sleeve.

[0008] Preferably, a lifting guide block is fixed to the lower edge of the grinding hopper, and a lifting guide groove is provided on the inner wall of the raw material mixing cylinder, with the lifting guide block slidably connected in the lifting guide groove of the raw material mixing cylinder.

[0009] Preferably, a compaction space is provided between the grinding hopper and the receiving hopper, and the feeding pipe is connected to the compaction space.

[0010] Preferably, a mounting frame is fixed to the upper end face of the raw material mixing cylinder, a drive motor is fixed to the upper part of the mounting frame, and the upper end of the stirring shaft is fixed to the output shaft of the drive motor.

[0011] This utility model provides a raw material mixing device for the production of citric acid disinfectant, which has the following advantages compared with the prior art:

[0012] The grinding mechanism allows the grinding funnel to move up and down along the inner wall of the raw material mixing cylinder during the mixing process. When the grinding funnel descends, it works in conjunction with the receiving bucket to crush the solid raw materials. After the solid raw materials are crushed, the particle size becomes smaller. This allows the small solid particles to come into full contact with the solvent through the discharge hole on the receiving bucket, which helps to improve the dissolution rate. At the same time, the rotating receiving bucket makes it easy to control the uniform addition of small solid particles into the mixing chamber of the raw material mixing cylinder.

[0013] With the addition of a grinding funnel and a receiving bucket, the rotating receiving bucket can mix the solvent when the solvent fluid level overflows the receiving bucket. This method not only ensures that the solid particle material residue is effectively dissolved in the solvent, but also prevents blockage and cleans the feeding channel. In addition, the grinding funnel is always covered above the centrifuged solvent to reduce the problem of solvent spilling out of the raw material mixing cylinder due to excessive solvent volume or excessive centrifugal force.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a raw material mixing device for the production of citric acid disinfectant, including a raw material mixing cylinder 1. A stirring shaft 2 is rotatably connected inside the raw material mixing cylinder 1. A horizontal stirring rod 3 is provided on the lower part of the side surface of the stirring shaft 2. A grinding mechanism 4 is provided inside the raw material mixing cylinder 1. The grinding mechanism 4 includes a reciprocating grinding funnel 5 and a receiving bucket 6 fixed on the stirring shaft 2. A feeding pipe 8 is fixed on the upper end face of the grinding funnel 5. A lifting screw sleeve 9 is fixed on the inner wall of the feeding pipe 8. A reciprocating screw section 13 is provided in the middle section of the side surface of the stirring shaft 2. The reciprocating screw section 13 is threadedly connected to the lifting screw sleeve 9. During the rotation of the stirring shaft 2, since the grinding funnel 5 is threadedly connected to the rotating reciprocating screw section 13 through the lifting screw sleeve 9, the grinding funnel 5 reciprocates along the inner wall of the raw material mixing cylinder 1 during the mixing process.

[0021] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that a lifting guide block 10 is fixed to the lower edge of the grinding hopper 5, and a lifting guide groove 12 is provided on the inner wall of the raw material mixing cylinder 1. The lifting guide block 10 is slidably connected in the lifting guide groove 12 of the raw material mixing cylinder 1.

[0022] Further as Figure 4 As shown, it is worth noting that the grinding funnel 5 is slidably connected to the inside of the raw material mixing cylinder 1, and the receiving bucket 6 is rotatably connected to the inside of the raw material mixing cylinder 1. The inner wall of the receiving bucket 6 is provided with a leakage hole 11. A grinding space 7 is provided between the grinding funnel 5 and the receiving bucket 6. The feeding pipe 8 is connected to the grinding space 7. When the solvent fluid surface overflows the receiving bucket 6, the rotating receiving bucket 6 can play the role of mixing solvent.

[0023] Further as Figure 1 As shown, it is worth noting that the upper end face of the raw material mixing cylinder 1 is fixed with a mounting frame 14, the upper part of the mounting frame 14 is fixed with a drive motor 15, and the upper end of the stirring shaft 2 is fixed on the output shaft of the drive motor 15.

[0024] This solution has the following working process: Before use, the liquid raw materials for making disinfectant are added to the mixing chamber of the raw material mixing cylinder 1 through the feeding pipe 8. Then, solid raw materials such as citric acid are added to the crushing space 7 between the crushing funnel 5 and the receiving bucket 6 through the feeding pipe 8. During use, the drive motor 15 drives the stirring shaft 2 and the horizontal stirring rod 3 on the surface to rotate inside the raw material mixing cylinder 1. During the rotation of the stirring shaft 2, the crushing funnel 5 is threadedly connected to the rotating reciprocating screw section 13 through the lifting screw sleeve 9. Thus, during the stirring process, the crushing funnel 5 moves up and down along the inner wall of the raw material mixing cylinder 1. When the crushing funnel 5 descends, it cooperates with the receiving bucket 6 to crush the solid raw materials. After the solid raw materials are crushed, the particle size becomes smaller. This allows the small solid particles of raw materials to fully contact the solvent through the leakage hole 11 on the receiving bucket 6, which is beneficial to improving the dissolution rate. At the same time, the rotating receiving bucket 6 makes it easy to control the uniform addition of small solid particles of raw materials to the mixing chamber of the raw material mixing cylinder 1.

[0025] When feeding material into the mixing chamber of the raw material mixing cylinder 1 through the receiving bucket 6, the speed of the drive motor 15 is controlled to increase the centrifugal force of the solvent in the raw material mixing cylinder 1. When the solvent fluid surface overflows the receiving bucket 6, the rotating receiving bucket 6 can play the role of mixing the solvent. At the same time, the solid particles remaining on the receiving bucket 6 and the grinding funnel 5 come into contact with the solvent and mix until they are completely dissolved. This method can not only ensure that the solid particles are effectively dissolved in the solvent, but also prevent blockage and clean the feeding channel. In addition, the grinding funnel 5 is always covered above the centrifugal solvent to reduce the trouble of solvent spilling out of the raw material mixing cylinder 1 due to excessive solvent volume or excessive centrifugal force.
