Description

Technical Field

[0001] This application relates to the field of chemical raw material screening and grinding technology, and in particular to a chemical raw material screening and grinding device. Background Technology

[0002] The screening and grinding of chemical raw materials is a crucial step in chemical production, directly impacting the quality and performance of the final product. Currently, the chemical industry has increasingly stringent requirements for the particle size of raw materials, especially in high-end chemicals and pharmaceutical intermediates, where the uniformity and fineness of the raw materials have a decisive influence on product performance.

[0003] The published patent document CN217646473U discloses a grinding device for screening chemical raw materials, including a box body. A material discharge cylinder is connected to the inner top of the box body. A screen is slidably connected to the inner side of the box body. An anti-fall frame is fixedly connected to the top of the screen. A locking block is fixedly connected to the left end of the anti-fall frame and slidably connected to the box body. A second spring is fixedly connected to the top of the anti-fall frame, and the other end of the second spring is fixedly connected to the box body. A sealing plate is provided at the top of the screen and fits against the anti-fall frame. A pull frame is fixedly connected to the rear end of the sealing plate. In this invention, a vibrating motor generates excitation force to ensure screen vibration for reliable screening of raw materials. A heating rod ensures reliable heating of the grinding rollers for stable grinding, thereby reliably dehumidifying small particles of raw materials while grinding them. A temperature sensor prevents high temperatures inside the box from causing sublimation of raw materials and polluting the environment, increasing the practicality of the device.

[0004] When the above devices are in use, the waste residue after screening will remain on the top of the screen and cannot be cleaned in time, which may affect the efficiency of subsequent screening and feeding. In addition, the screening pressure of a single-layer screen is relatively high, which may cause blockage. Moreover, the machine needs to be stopped when cleaning it, which may lead to a decrease in production efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art, this application provides a chemical raw material screening and grinding device, which overcomes the shortcomings of the prior art. It aims to solve the problem that when the above-mentioned devices in the prior art are used, the waste residue after screening will remain on the screen and cannot be cleaned in time, which may affect the efficiency of subsequent screening and feeding. In addition, the screening pressure of the single-layer screen is too high, which may cause blockage. Moreover, the machine needs to be stopped when cleaning it, which may lead to a decrease in production efficiency.

[0006] To achieve the above objectives, this application provides the following technical solution: a chemical raw material screening and grinding device, comprising a grinding box, screening grooves on both sides of the grinding box, two sets of screening mechanisms arranged inside the grinding box, the two sets of screening mechanisms being arranged vertically and facing different directions, the positions of the two sets of screening grooves corresponding to the screening mechanisms, a grinding frame arranged below the two sets of screening mechanisms, a grinding roller arranged between the two sets of grinding frames, a receiving box arranged at the bottom of the two sets of grinding frames, the screening mechanism comprising a screening screen, a hinged member arranged on one side of the screening screen, the hinged member being fixedly connected to the interior of the grinding box, a vibrating frame arranged on the other side of the screening screen, a vibration groove arranged on one side of the vibrating frame, a connecting groove arranged at the bottom of the vibrating frame, a vibrator installed at the bottom of the vibrating frame, a movable block fixedly connected to one end of the screening screen, the movable block being slidably connected to the interior of the vibrating frame, the top of the vibrator penetrating the connecting groove and fixedly connected to the bottom of the movable block, the two sets of screening screens having different filter apertures, and a slag collection mechanism arranged outside the two sets of screening grooves.

The screening apertures of the two sets of screening screens are different, which can better classify the particle size of the materials and share the screening pressure, thereby improving the screening effect. The screens are vibrated by a vibrator, which will send the screened waste residue or large particles through the screening tank into the slag collection mechanism for classified collection. The screened materials will be quickly ground by the grinding rollers and then enter the collection box. In this way, the screening and filtration of materials can be completed quickly, and the separation and collection of waste residue can be completed without stopping the machine. The filtered waste residue is classified, making subsequent cleaning and utilization more convenient.

[0013] By adopting the above technical solution and setting up a fixed frame, the slag collection bin can be quickly pulled out from inside the fixed frame, making it more convenient to clean and replace it, thus improving the practicality of the device.

[0014] As a preferred technical solution of this application, an inclined block is provided above both sets of grinding racks, and an observation window is provided on the front of the grinding box.

[0016] As a preferred technical solution of this application, a control panel is provided on the front of the grinding box, and the control panel is electrically connected to the feeding mechanism, the screening mechanism and the grinding roller.

[0017] By adopting the above technical solution and setting up a control panel, the device can be operated, the operating data can be better adjusted, and the device's practicality can be improved.

[0018] As a preferred technical solution of this application, a fixing groove is provided below each of the two sets of grinding frames, and a filter screen is provided between the two sets of fixing grooves, with the filter screen located directly below the grinding roller.

[0020] As a preferred technical solution of this application, the top of the feeding hopper is provided with a top cover, and the top cover and the feeding hopper are hinged to each other.

[0021] By adopting the above technical solution, the top cover can shield the feed hopper, ensuring that no debris falls directly into the feed hopper and affects the normal use of the device.

[0022] The beneficial effects of this application are:

[0023] 1. By setting up a screening mechanism, the two sets of screening mechanisms can quickly screen the materials entering the grinding box. The screening apertures of the two sets of screening screens are different, which can better classify the particle size of the materials and can share the screening pressure, thereby improving the screening effect. The screens are vibrated by a vibrator, and the waste residue or large particles after screening are fed into the slag collection mechanism for classified collection.
