Description

Technical Field

[0001] This application relates to the field of grinding equipment technology, and more particularly to a chemical raw material grinding machine. Background Technology

[0002] Humans have a very close relationship with the chemical industry, which is pervasive in all aspects of life. In modern life, we can hardly live without chemical products anytime and anywhere. From material life such as clothing, food, housing, and transportation to spiritual life such as culture, art, and entertainment, chemical products are needed to serve us. These chemical products all require the use of corresponding chemical raw materials for production. Since different chemical industries use different raw materials and obtain different products, the various chemical processes are very different, and grinding machines are needed to grind the chemical raw materials.

[0003] A search revealed a Chinese patent for a chemical raw material grinding machine (authorization announcement number CN219850014U), comprising a base plate and a support plate. The base plate has a raw material support mechanism, which includes a support tray and a base. The base is fixed to the base plate. The support plate has a grinding mechanism, which includes a linkage component and a grinding component. The grinding component is rotatably connected to the linkage component. This patented technology can support the chemical raw material to be ground through the support tray in the raw material support mechanism. The servo motor in the linkage component drives the drive gear and belt synchronously, thereby causing the grinding component to rotate eccentrically on the connecting plate. This allows the grinding head to slide on the support tray and apply pressure, achieving both grinding and stirring effects. This prevents the raw material from accumulating under pressure, thus avoiding the need to stop the operation to break up the raw material during grinding, greatly improving work efficiency.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that the tray in the grinding machine is an open design and the entire tray needs to rotate, which can easily cause the chemical raw materials to leak out due to centrifugal force. This not only wastes the raw materials but may also cause environmental pollution and safety hazards in the workshop. On the other hand, the rotation of the tray cannot effectively guide the raw materials into the grinding range of the grinding head. A large amount of raw materials tend to accumulate on the edge of the tray, making it difficult to form efficient contact with the grinding head and significantly reducing the grinding efficiency. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the main objective of this application is to provide a chemical raw material grinding mill.

[0006] The technical solution of this application is as follows: a chemical raw material grinding mill includes a grinding tank, a sliding sleeve rod is slidably connected inside the grinding tank, a grinding head is slidably connected inside the grinding tank, the bottom end of the sliding sleeve rod is fixedly connected to the grinding head, an air outlet pipe is fixedly connected at equal intervals inside the grinding head, an air box is fixedly connected to the top of the grinding tank, a fixed pipe is fixedly connected to the bottom of the air box and above the air outlet pipe, the bottom of the fixed pipe extends into the interior of the grinding tank and is fixedly connected to a corrugated pipe, the end of the corrugated pipe away from the fixed pipe is fixedly connected to the corresponding air outlet pipe, and the internal spaces of the air box, the fixed pipe, the corrugated pipe and the air outlet pipe are interconnected.

[0007] By adopting the above technical solution, the air pump supplies air to the air outlet pipe through the air box, fixed pipe and corrugated pipe. The airflow is sprayed out through the dustproof net to blow away the accumulated raw materials, ensuring that the raw materials fully contact the grinding head and avoiding uneven grinding caused by local accumulation.

[0012] In a preferred embodiment, the grinding jar is provided with a base plate at the bottom, the grinding jar is fixedly installed on the top of the base plate, and a stainless steel filter screen is fixedly connected to the bottom of the inner wall of the grinding jar.

[0013] By adopting the above technical solution and setting up a stainless steel filter screen, the ground raw materials can be screened in real time.

[0014] In a preferred embodiment, a dustproof net is fixedly connected to the side of the air outlet pipe away from the corrugated pipe, and the grinding head is in contact with the inner wall of the grinding tank.

[0015] By adopting the above technical solution and setting up a dustproof net, the amount of chemical raw materials entering the corrugated pipe from the grinding tank can be reduced.

[0016] In a preferred embodiment, a drive motor is fixedly mounted on the outer side of the support base, and the output shaft of the drive motor is fixedly connected to the rotation shaft of the connecting rod.

[0017] By adopting the above technical solution, the rotation of the output shaft of the drive motor is used to drive the connecting rod to make circular motion.

[0018] In a preferred embodiment, a feed hopper is fixedly connected to the front side of the grinding jar, a collection box is placed on the top of the bottom plate, and two through holes are opened on the top of the grinding jar.

[0019] By adopting the above technical solution and setting through holes, air on the grinding head can be discharged as quickly as possible.

[0020] Compared with the prior art, the advantages and positive effects of this application are as follows: 1. In this application, the solution forms a relatively closed grinding space through the fitting design of the grinding tank and the grinding head, which can reduce the leakage path of chemical raw materials. Moreover, the entire grinding operation is completed in the grinding tank, which can reduce the environmental pollution and safety hazards in the workshop caused by raw material leakage and reduce the cleaning cost in the production process. At the same time, the air pump supplies air to the air outlet pipe through the air box, fixed pipe and corrugated pipe. The airflow is sprayed out through the dust screen to blow away the accumulated raw materials, ensuring that the raw materials fully contact the grinding head and avoiding uneven grinding caused by local accumulation.

[0021] 2. In this application, the rotation of the connecting rod can drive the sliding sleeve rod to move up and down with the linkage, so that the grinding head can reciprocate inside the grinding tank, in order to cooperate with the fit design between the grinding head and the inner wall, so as to continuously squeeze and grind the raw material.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] Reference Figure 1-5 A chemical raw material grinding mill includes a grinding tank 1, a sliding sleeve 4 slidably connected inside the grinding tank 1, a grinding head 11 slidably connected inside the grinding tank 1, the bottom end of the sliding sleeve 4 being fixedly connected to the grinding head 11, and air outlet pipes 15 being fixedly connected at equal intervals inside the grinding head 11. An air box 2 is fixedly connected to the top of the grinding tank 1, and fixed pipes 12 are fixedly connected to the bottom of the air box 2 and above the air outlet pipes 15. The bottom of the fixed pipes 12 extends into the interior of the grinding tank 1 and is fixedly connected to a corrugated pipe 13. The end of the corrugated pipe 13 away from the fixed pipe 12 is fixedly connected to the corresponding air outlet pipe 15. The air box 2, the fixed pipe 12, and the fixed pipe 13 are all fixedly connected. The internal spaces of the fixed pipe 12, the corrugated pipe 13, and the air outlet pipe 15 are connected. This solution forms a relatively closed grinding space through the fitting design of the grinding tank 1 and the grinding head 11, which can reduce the leakage path of chemical raw materials. Moreover, the entire grinding operation is completed in the grinding tank 1, which can reduce the environmental pollution and safety hazards in the workshop caused by raw material leakage and reduce the cleaning cost in the production process. At the same time, the air pump 3 supplies air to the air outlet pipe 15 through the air box 2, the fixed pipe 12, and the corrugated pipe 13. The airflow is sprayed out through the dustproof net 14 to blow away the accumulated raw materials, ensuring that the raw materials fully contact the grinding head 11 and avoiding uneven grinding caused by local accumulation.

[0026] Specifically, a support base 5 is fixedly connected to the top of the grinding tank 1. A connecting rod 7 is rotatably installed on one side of the support base 5. A linkage 6 is rotatably connected to the end of the connecting rod 7 away from the support base 5. The top of the sliding sleeve rod 4 is rotatably connected to the linkage 6. Through the rotation of the connecting rod 7, the sliding sleeve rod 4 can be driven up and down by the linkage 6, so that the grinding head 11 can reciprocate inside the grinding tank 1. This is to cooperate with the design of the grinding head 11 and the inner wall to continuously squeeze and grind the raw material. An air pump 3 is fixedly installed on the top of the grinding tank 1 and on the inner circumference of the air box 2. The output end of the air pump 3 extends into the interior of the air box 2. A base plate 9 is provided at the bottom of the grinding tank 1. The grinding tank 1 is fixedly installed on the top of the base plate 9. With the setting of the stainless steel filter screen 10, the ground raw material can be screened in real time. The raw material that meets the particle size requirements falls into the collection box 17, while the raw material that does not meet the requirements is retained for further grinding, so as to greatly improve the grinding efficiency. A stainless steel filter screen 10 is fixedly connected to the bottom of the inner wall of the grinding tank 1.

[0027] Specifically, a dustproof net 14 is fixedly connected to the side of the air outlet pipe 15 away from the corrugated pipe 13. The grinding head 11 is in contact with the inner wall of the grinding tank 1. A drive motor 8 is fixedly installed on the outer side of the support base 5. The rotation of the output shaft of the drive motor 8 drives the connecting rod 7 to make a circular motion. The output shaft of the drive motor 8 is fixedly connected to the rotation shaft of the connecting rod 7. A feed hopper is fixedly connected to the front side of the grinding tank 1, which makes it convenient for workers to put chemical raw materials into the grinding tank 1 through the feed hopper. A collection box 17 is placed on the top of the bottom plate 9. Two through holes 16 are opened on the top of the grinding tank 1 to expel the air on the grinding head 11 as soon as possible.

[0028] Working principle: First, the operator can put the chemical raw materials into the grinding tank 1 through the feed hopper and close the hopper cover. Then, the external controller controls the drive motor 8 and air pump 3 to start. The rotation of the output shaft of the drive motor 8 drives the connecting rod 7 to make a circular motion, which in turn drives the sliding sleeve rod 4 to move up and down with the linkage 6. This causes the grinding head 11 to reciprocate inside the grinding tank 1. With the grinding head 11 and the inner wall in close contact, the raw materials are continuously squeezed and ground. When the grinding head 11 moves downward and does not contact the stainless steel filter screen 10, the air pump 3 can be controlled to supply air to the air outlet pipe 15. The airflow is sprayed out through the dustproof net 14 to blow away the accumulated raw materials, ensuring that the raw materials fully contact the grinding head 11 and avoiding uneven grinding caused by local accumulation. This solution forms a relatively closed grinding space through the close contact design of the grinding tank 1 and the grinding head 11, which can reduce the leakage path of chemical raw materials. Moreover, the entire grinding operation is completed inside the grinding tank 1, which can reduce the environmental pollution and safety hazards in the workshop caused by raw material leakage and reduce the cleaning cost in the production process.
