Description

Technical Field

[0001] This utility model relates to the field of chemical product manufacturing technology, specifically a grinding device for chemical product manufacturing. Background Technology

[0002] In chemical production, grinding equipment is one of the key pieces of equipment. It is used to grind raw materials into the required powder or granular materials. Traditional grinding equipment usually only grinds the material once, that is, the raw material is directly put into the grinding chamber and ground by the friction, extrusion and other forces of the grinding media.

[0003] However, single grinding often results in uneven particle size of the ground material. Due to differences in the physical properties of raw materials, such as particle size, hardness, and density, single grinding cannot guarantee that all materials can achieve the ideal grinding effect. Some materials may become too large due to insufficient grinding, while others may become too small due to over-grinding, or even form powder. Such unevenly sized materials can easily affect the quality and performance of subsequent products. Therefore, we need to propose a grinding device for the production of chemical products.

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] A grinding device for chemical product production includes a housing 1. A feed hopper 2 is fixedly connected to the top of the housing 1. A power assembly 3 for grinding raw materials is installed inside the housing 1. A guide hopper 4 is fixedly embedded at the bottom of the housing 1, and a discharge pipe 5 is fixedly connected to the bottom of the guide hopper 4. The power assembly 3 can grind the material inside the housing 1. The ground material enters the discharge pipe 5. A fine material outlet 6 is opened at the bottom of the discharge pipe 5. A discharge pipe 7 is fixedly embedded inside the fine material outlet 6. A filter screen 15 is fixedly connected to the top of the discharge pipe 7. A coarse material outlet 8 is opened at the bottom of the discharge pipe 5. After the ground material is screened by the filter screen 15, the fine material passes directly through the filter screen 15 and is discharged from the discharge pipe 7. Fine materials are collected uniformly through the collection box 11, while coarse materials are discharged directly through the coarse material outlet 8. The collected coarse materials can be put back into the feed hopper 2 and repeatedly ground until the target fineness is achieved. Connecting frames 9 are fixedly connected to the two side walls of the discharge pipe 5, and mounting blocks 10 are fixedly connected to the bottom of the two sets of connecting frames 9. The collection box 11 is set between the two sets of mounting blocks 10, and clamping components 12 for quick positioning of the collection box 11 are set on one side wall of the two sets of mounting blocks 10. By setting the connecting frames 9, mounting blocks 10 and clamping components 12 together, the collection box 11 is quickly locked and positioned, avoiding the displacement of the collection box 11 during use, which helps to improve the stability of the device.

[0025] Specifically, the power assembly 3 includes two sets of grinding rollers 301. The two ends of the two sets of grinding rollers 301 are rotatably mounted on the inner walls of the two sides of the housing 1. One end of each set of grinding rollers 301 penetrates the housing 1 and is fixedly connected to a toothed disc 302. The two sets of toothed discs 302 mesh with each other. The other end of one set of grinding rollers 301 penetrates the housing 1 and is connected to a drive motor 303. By setting the drive motor 303, grinding rollers 301 and toothed discs 302 to work together, the material inside the housing 1 is ground.

[0026] Furthermore, the drive motor 303 is fixedly installed on one side wall of the housing 1. One end of the output shaft of the drive motor 303 is fixedly connected to one end of one set of grinding rollers 301. The drive motor 303 can be electrically connected to the controller (not shown in the figure). The circuit connection is a mature existing technology. The specific connection method and working principle will not be elaborated here. The drive motor 303 can be started and stopped through the controller.

[0027] Furthermore, fixing plates 13 are fixedly connected to the two side walls of the collection box 11 respectively, and fixing grooves 14 adapted to the fixing plates 13 are respectively opened on the opposite side walls of the two sets of mounting blocks 10. The two sets of fixing plates 13 are slidably inserted into the two sets of fixing grooves 14 respectively. By setting the fixing plates 13 and fixing grooves 14 to cooperate, the collection box 11 is limited.

[0028] Specifically, the clamping assembly 12 includes a fixing sleeve 1201, which is fixedly installed on one side wall of the mounting block 10. A positioning rod 1202 is slidably inserted into the inside of the fixing sleeve 1201. One end of the positioning rod 1202 passes through the mounting block 10 and is inserted into the inside of the fixing plate 13. The other end of the positioning rod 1202 is fixedly connected to a pull block 1203. When the fine material inside the collection box 11 is full, the pull block 1203 can be pulled, thereby moving the positioning rod 1202 until the positioning rod 1202 is separated from the fixing plate 13. At this time, the collection box 11 can be disassembled, which makes it easier to discharge the fine material inside the collection box 11.

[0029] Furthermore, it also includes a telescopic spring 1204, one end of which is fixedly connected to one side wall of the pull block 1203, and the other end of which is fixedly connected to one end of the fixed sleeve 1201. The telescopic spring 1204 is movably sleeved on the outer wall of the positioning rod 1202.

[0030] A positioning blind hole 16 adapted to the positioning rod 1202 is provided on one side wall of the fixing plate 13. One end of the positioning rod 1202 is inserted into the inside of the positioning blind hole 16. When the collection box 11 needs to be installed, the pull block 1203 can be pulled directly to move the positioning rod 1202 to be measured. At this time, the telescopic spring 1204 is in the stretched state. Then, the fixing plates 13 on both sides of the collection box 11 are respectively inserted into the two sets of fixing slots 14. When the positioning blind hole 16 is aligned with the end of the positioning rod 1202, the return force of the telescopic spring 1204 can be used to drive the positioning rod 1202 to be firmly inserted into the inside of the positioning blind hole 16, thereby achieving the effect of quickly clamping the collection box 11.

[0031] In addition, it also includes two sets of lifting handles 17, which are fixedly connected to the two side walls of the collection box 11 respectively. By setting the lifting handles 17, it is convenient for staff to move and transfer the collection box 11.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
