Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a special grinding machine for calcium hydroxide. Background Art

[0002] An important application of calcium hydroxide is as a flocculant for water and sewage treatment. It can form fluffy charged solids, which helps to remove smaller particles from the water, resulting in a more transparent product. Calcium hydroxide is in powder form under normal conditions, but it may clump when stored due to contact with water in the air. Therefore, roughly processed and improperly stored calcium hydroxide powder needs to be polished before being put into use.

[0003] Most existing grinding devices can only grind block objects into powder, and calcium hydroxide itself is in powder form. Therefore, it is difficult to grind it into smaller particles through existing grinding devices, and it is difficult to control the grinding accuracy. Therefore, a grinding machine dedicated to calcium hydroxide is needed. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a special grinding machine for calcium hydroxide, which can be applied to calcium hydroxide powder so as to grind it into powder with smaller particles.

[0005] The technical solution for achieving the purpose of the utility model is: a special grinding machine for calcium hydroxide, comprising a shell, a grinding cylinder fixedly connected to the inner wall of the shell, a grinding seat rotatably connected inside the grinding cylinder, a motor fixedly connected to the bottom inner wall of the shell, the output shaft of the motor fixedly connected to the grinding seat, a suction assembly is arranged on the shell, the suction assembly comprises a pipeline, a piston, a suction pipe and a feed box, the pipeline and the suction pipe are fixedly connected to the shell, the piston is slidably connected to the inner wall of the pipeline, the feed box is fixedly connected to the shell, and an auxiliary assembly is arranged inside the shell.

[0006] Preferably, the suction assembly also includes a sprocket, a chain and a sliding rod, one sprocket is rotatably connected to the inner wall of the outer shell, the other sprocket is fixedly connected to the output shaft of the motor, the chain is engaged with the two sprockets, the sliding rod is fixedly connected to one sprocket, and the sliding rod is slidably connected to the piston.

[0007] Preferably, the suction assembly further comprises a first one-way valve, and the first one-way valve is fixedly connected to the inner wall of the pipeline.

[0008] Preferably, the auxiliary component comprises a sliding tube and a spring, the sliding tube is slidably connected to the pipeline, and the spring is fixedly connected between the inner wall of the pipeline and the sliding tube.

[0009] Preferably, the auxiliary component further comprises a collecting pipe and a filter screen, the collecting pipe is slidably connected to the sliding pipe, and the filter screen is arranged on the sliding pipe, the collecting pipe and the grinding seat.

[0010] Preferably, the auxiliary component further comprises a bottom hole and a second one-way valve, the bottom hole is opened at the bottom of the grinding cylinder, and the second one-way valve is fixedly connected to the bottom of the grinding seat.

[0011] Compared with the prior art, the utility model has the following significant advantages:

[0012] First, in the utility model, calcium hydroxide powder can be poured into the outer shell through the feed box, and the powder will fall into the grinding cylinder. Then, the motor is started, and the output shaft of the motor rotates to drive the grinding seat to rotate. The edge of the grinding seat will contact the inner wall of the grinding cylinder, so that the powder mixed in the gap between the two is ground into powder with smaller particles.

[0013] Second: In the utility model, during the grinding process, the output shaft of the motor can drive the chain transmission, so that the slide rod rotates with the sprocket. The rotation of the slide rod will cause the piston to slide back and forth. The reciprocating movement of the piston will form an air pressure change in the outer shell. When the piston moves to the right, high pressure is generated in the space where the motor is located, and the air is discharged to the inside of the grinding seat through the second one-way valve, and then discharged from the filter screen on the grinding seat. At this time, the calcium hydroxide powder will be blown up, and at the same time, the piston moves to the right to form a negative pressure in the pipeline. The negative pressure passes through the slide pipe and the collecting pipe, and finally absorbs the powder blown up below through the suction pipe and collects it in the collecting pipe. Therefore, as the motor continues to rotate, the calcium hydroxide powder is continuously ground, and powder is continuously blown up, and the blown powder is then sucked into the collecting pipe. The cover on the top of the outer shell can be opened to take out the collecting pipe to take out the powder collected therein. Since the powder therein is absorbed by the airflow, the particles can be guaranteed to be small and dry. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-Figure 4 As shown, a special grinding machine for calcium hydroxide comprises a shell 1, a grinding cylinder 2 is fixedly connected to the inner wall of the shell 1, a grinding seat 3 is rotatably connected inside the grinding cylinder 2, a motor 4 is fixedly connected to the inner wall of the bottom of the shell 1, the output shaft of the motor 4 is fixedly connected to the grinding seat 3, a suction component 5 is arranged on the shell 1, the suction component 5 comprises a pipeline 51, a piston 52, a suction pipe 57 and a feed box 58, the pipeline 51 and the suction pipe 57 are fixedly connected to the shell 1, the pipeline 51 is divided into three ends, two ends of which are respectively connected to the top and the bottom of the shell 1, and the other end is connected to the outside, the piston 52 is slidably connected to the inner wall of the pipeline 51, the feed box 58 is fixedly connected to the shell 1, and an auxiliary component 6 is arranged inside the shell 1.

[0024] Furthermore, the suction assembly 5 also includes a sprocket 53, a chain 54 and a sliding rod 55, one sprocket 53 is rotatably connected to the inner wall of the outer shell 1, the other sprocket 53 is fixedly connected to the output shaft of the motor 4, the chain 54 is engaged with the two sprockets 53, the sliding rod 55 is fixedly connected to one sprocket 53, and the sliding rod 55 is slidably connected to the piston 52.

[0025] Furthermore, the suction assembly 5 also includes a first one-way valve 56, which is fixedly connected to the inner wall of the pipe 51. Two first one-way valves 56 are provided, which are respectively arranged at the two ends of the pipe 51, and the two have different directions. One can only exhaust from the shell 1 to the outside, and the other can only transmit negative pressure when the piston 52 moves, so that the top of the pipe 51 can inhale.

[0026] Furthermore, the auxiliary component 6 includes a sliding tube 61 and a spring 62 . The sliding tube 61 is slidably connected to the pipe 51 , and the spring 62 is fixedly connected between the inner wall of the pipe 51 and the sliding tube 61 .

[0027] Furthermore, the auxiliary component 6 also includes a collecting pipe 63 and a filter 64. The collecting pipe 63 is slidably connected to the sliding pipe 61. The filter 64 is arranged on the sliding pipe 61, the collecting pipe 63 and the grinding seat 3. The mesh density and size of the filter 64 can allow air to circulate, but calcium hydroxide powder cannot pass through.

[0028] Furthermore, the auxiliary component 6 also includes a bottom hole 65 and a second one-way valve 66. The bottom hole 65 is opened at the bottom of the grinding cylinder 2. The second one-way valve 66 is fixedly connected to the bottom of the grinding seat 3. The second one-way valve 66 only allows air to be poured in from the bottom to the top, so that the filter screen 64 on the grinding seat 3 can spray air to the outside, so that the calcium hydroxide powder is blown up to form dust after grinding.

[0029] The specific working method is: first, pour the calcium hydroxide powder into the outer shell 1 through the feed box 58, and the powder will fall into the grinding cylinder 2, then start the motor 4, and the output shaft of the motor 4 rotates to drive the grinding seat 3 to rotate, and the edge of the grinding seat 3 will contact the inner wall of the grinding cylinder 2, so as to grind the powder mixed in the gap between the two and grind it into powder with smaller particles. During the grinding process, the output shaft of the motor 4 can drive the chain 54 to drive, so that the slide bar 55 rotates with the sprocket 53, and the rotation of the slide bar 55 will cause the piston 52 to slide back and forth. The reciprocating movement of the piston 52 will form an air pressure change in the outer shell 1. As shown in the figure, when the piston 52 moves to the left, the air is discharged from the middle section of the pipe 51, and the air hole at the bottom of the outer shell 1 takes in air. When the plug 52 moves to the right, high pressure is generated in the space where the motor 4 is located, and the air is discharged to the inside of the grinding seat 3 through the second one-way valve 66, and then discharged from the filter 64 on the grinding seat 3. At this time, the calcium hydroxide powder will be blown up, and at the same time, the piston 52 moves to the right to form a negative pressure in the pipeline 51. The negative pressure passes through the slide pipe 61 and the collecting pipe 63, and finally absorbs the powder blown up from below through the suction pipe 57 and collects it in the collecting pipe 63. Therefore, as the motor 4 continues to rotate, the calcium hydroxide powder is continuously ground and the powder is continuously blown up, and the blown powder is then sucked into the collecting pipe 63. The cover on the top of the outer shell 1 can be opened to take out the collecting pipe 63 to take out the powder collected therein. Since the powder therein is absorbed by the airflow, the particles can be guaranteed to be small and dry.
