Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical raw material technology, specifically to a fine pulverizing device for chemical raw materials. Background Technology
[0002] Chemical raw materials refer to substances used in chemical reactions or synthesis, including inorganic and organic chemical raw materials. The particle size, shape, purity, and other properties of chemical raw materials affect the rate, efficiency, selectivity, and quality of the products in chemical reactions. Therefore, pulverizing chemical raw materials can increase their surface area, enhance contact with the reaction medium, and promote the chemical reaction. It can also improve the uniformity, flowability, and solubility of the chemical raw materials, facilitating their storage, transportation, and use.
[0003] Application number CN202420430885.8 discloses a fine pulverizing device for chemical raw materials, including a pulverizing assembly. The pulverizing assembly includes a pulverizing box, a feed pipe with a flip-top at the top, two pulverizing rollers inside the pulverizing box, and a discharge hopper at the bottom. A screening assembly is connected to the bottom of the discharge hopper, and the screening assembly includes a screening box with a discharge port on its left side. A screen plate is located inside the screening box, and a support plate is located on the left side of the bottom of the screening box. A dust collection assembly is located at the bottom left side of the support plate. In this fine pulverizing device, an exhaust fan discharges air from the dust collection box, creating negative pressure inside the dust collection box. This negative pressure then generates suction within the dust collection hood. When dust is discharged from the discharge port, it enters the dust collection hood and is drawn into the air duct, thus preventing the dust from directly spreading into the air and preventing workers from inhaling chemical raw material dust.
[0004] However, the grinding component of this device is fixedly installed at the bottom of the screening component by multiple connecting rods. When the grinding component needs maintenance, it is inconvenient for maintenance personnel to inspect and repair the grinding component. Furthermore, if there is chemical material blockage inside the discharge pipe connecting the grinding component and the screening component, it is difficult to clean the inside of the discharge pipe, which leads to reduced production efficiency and delayed production progress. Therefore, a fine grinding device for chemical raw materials is proposed. Utility Model Content
[0005] The main objective of this invention is to provide a fine pulverizing device for chemical raw materials, which can effectively solve the problems in the background art.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A fine pulverizing device for chemical raw materials includes a mounting shell and a grinding assembly. The mounting shell is fixedly installed at the bottom end of the screening assembly.

The second sleeve is located inside the mounting housing, and the interior of the second sleeve communicates with the interior of the screening component.
[0011] By adopting the above technical solution, after the grinding component is installed in place, the telescopic tube can slide up and down inside the second sleeve to adjust the connection status with the first sleeve, thereby realizing the connection or disconnection between the screening component and the grinding component.
[0012] Specifically, a first sleeve is fixedly connected to the top of the grinding assembly, the first sleeve is in communication with the interior of the grinding assembly, and the bottom end of the telescopic tube is inserted into the interior of the first sleeve.
[0013] By adopting the above technical solution, after the grinding assembly is installed, the telescopic tube is inserted into the first sleeve, so that the material in the screening assembly can enter the grinding assembly for further processing through the second sleeve, the telescopic tube and the first sleeve.
[0014] Specifically, the outer side of the mounting housing is provided with a groove, and there are two grooves. A positioning rod is vertically installed inside the two grooves, and the positioning rod is located directly above the slide groove.
[0015] By adopting the above technical solution, the positioning rod is used to limit the positioning block after the grinding assembly is installed in place, to prevent it from rotating or moving accidentally, and to ensure the stability of the grinding assembly.
[0016] Specifically, the inner bottom of the slide is provided with a first insertion hole located directly below the positioning rod, and the inside of the positioning block is provided with a second insertion hole. Both the first insertion hole and the second insertion hole are used for the positioning rod to pass through.
[0017] By adopting the above technical solution, when the positioning block slides along the groove to the innermost side, the first insertion hole and the second insertion hole are aligned. At this time, the positioning rod is pushed down so that it passes through the second insertion hole and the first insertion hole in sequence, thereby fixing the positioning block in the current position and realizing the installation and positioning of the grinding component.
[0018] Specifically, the upper outer side of the mounting housing is connected to an observation window via a hinge.
[0019] By adopting the above technical solution, the observation window can be opened outward, making it convenient for operators to observe the internal condition of the installation shell, such as the cooperation status of the positioning block and the positioning rod, the insertion status of the telescopic tube, etc., while also providing space for the operation of the telescopic tube.

The positioning groove 1 is used for the positioning block 9 to be installed and inserted, and the sliding groove 2 is used for the positioning block 9 to be slidably installed.
[0031] When the grinding assembly 7 needs maintenance or repair, first pull the positioning rod 3 inside the groove 11 upwards to remove it from the first insertion hole 4 and the second insertion hole 8, thus releasing the restriction on the positioning block 9. Then, open the observation window 10 and push the telescopic tube 13 upwards through the gap between the first sleeve 6 and the second sleeve 12 until the telescopic tube 13 is pulled out from inside the first sleeve 6. At this time, the internal communication between the screening assembly 14 and the grinding assembly 7 is cut off. Then, rotate the grinding assembly 7 so that it rotates along the direction of the slide 2 into the positioning groove 1. When the positioning block 9 is aligned with the positioning groove 1, the grinding assembly 7 can be pulled out from the mounting housing 5, thus facilitating the maintenance and repair of the grinding assembly 7.
[0032] The present invention also includes a second sleeve 12 fixedly connected to the bottom end of the screening component 14, a telescopic tube 13 movably inserted into the bottom end of the second sleeve 12, the second sleeve 12 being located inside the mounting housing 5, and the interior of the second sleeve 12 communicating with the interior of the screening component 14.
[0033] When in use, after the grinding component 7 is installed in place, the telescopic tube 13 can slide up and down inside the second sleeve 12 to adjust the connection with the first sleeve 6, thereby realizing the connection or disconnection between the screening component 14 and the grinding component 7.
[0034] The present invention also includes a first sleeve 6 fixedly connected to the top end of the grinding component 7, the first sleeve 6 communicating with the interior of the grinding component 7, and the bottom end of the telescopic tube 13 being inserted into the interior of the first sleeve 6.
[0035] When in use, after the grinding assembly 7 is installed, the telescopic tube 13 is inserted into the first sleeve 6, so that the material in the screening assembly 14 can enter the grinding assembly 7 for further processing through the second sleeve 12, the telescopic tube 13 and the first sleeve 6.
[0036] This utility model also includes a groove 11 provided on the outer side of the mounting housing 5. There are two grooves 11, and a positioning rod 3 is vertically installed inside the two grooves 11. The positioning rod 3 is located directly above the slide groove 2.
[0037] During use, the positioning rod 3 is used to limit the positioning block 9 after the grinding assembly 7 is installed in place, to prevent it from rotating or moving accidentally, and to ensure the stability of the grinding assembly 7.
[0038] The present invention also includes a first insertion hole 4 provided at the bottom of the inner side of the slide groove 2 directly below the positioning rod 3, and a second insertion hole 8 provided inside the positioning block 9. Both the first insertion hole 4 and the second insertion hole 8 are used for the positioning rod 3 to pass through.
[0039] When in use, when the positioning block 9 slides along the slide groove 2 to the innermost side, the first insertion hole 4 and the second insertion hole 8 are aligned. At this time, the positioning rod 3 is pushed down so that it passes through the second insertion hole 8 and the first insertion hole 4 in sequence, thereby fixing the positioning block 9 in the current position and realizing the installation and positioning of the grinding component 7.
[0040] This utility model also includes an observation window 10 connected to the upper outer side of the mounting housing 5 via a hinge.

[0042] When using this utility model, if the grinding component 7 needs maintenance or repair, the positioning rod 3 inside the groove 11 can be pulled upwards, so that the positioning rod 3 is pulled out from the first insertion hole 8 and the second insertion hole 4. Then, the observation window 10 is opened, and the telescopic tube 13 is pushed upwards from the gap between the first sleeve 6 and the second sleeve 12 until the telescopic tube 13 is pulled out from the first sleeve 6. Then, the grinding component 7 is rotated so that the grinding component 7 rotates in the direction of the slide groove 2 into the interior of the positioning groove 1. When the positioning block 9 is aligned with the positioning groove 1, the grinding component 7 can be pulled out from the mounting shell 5, which makes it convenient to maintain and repair the grinding component 7.
[0043] When it is necessary to install the grinding component 7 at the bottom of the screening component 14, simply align the positioning block 9 with the positioning groove 1, rotate the grinding component 7, and let the positioning block 9 slide along the direction of the slide groove 2 to the innermost side of the slide groove 2. Then push the positioning rod 3 in the groove 11 downwards, so that the positioning rod 3 passes through the second insertion hole 4 and the first insertion hole 8 in sequence, thereby limiting the positioning block 9. At this time, the fixed position of the grinding component 7 makes the first sleeve 6 just below the second sleeve 12.
