Description

Technical Field

[0001] The utility model relates to the technical field of furfural production equipment, in particular to a furfural raw material crushing and filtering equipment. Background Art

[0002] Furfural, also known as 2-furaldehyde, is the same substance as sugar aldehyde, and its scientific name is α-furaldehyde. It is a derivative in which the hydrogen atom at the 2-position of furan is replaced by an aldehyde group. It was initially obtained by heating rice bran with dilute acid, so it is called furfural. Furfural is formed by the hydrolysis of pentosan with acid to produce pentose, and then the dehydration cyclization of pentose. The main raw materials for production are agricultural and sideline products such as corncobs. There are various synthesis methods. Furfural is the most important derivative of the furan ring system, with active chemical properties. Many derivatives can be prepared through oxidation, condensation and other reactions, and it is widely used in industries such as synthetic plastics, medicine, and pesticides. The raw materials for furfural production are mainly corncobs, and the corncobs need to be crushed. Traditional crushing devices mainly crush corncobs through the internal crushing device.

[0003] According to the "A High-efficiency Furfural Production Crusher" disclosed in the Chinese patent application number CN202223119867.8, its structure includes a crusher housing, a support frame, a crushing chamber, a cavity, a crushing structure, a discharge port, a feeding component and an auxiliary component. By optimizing the feeding component, a baffle is arranged inside the feeding trough, and the feeding speed of corncobs is controlled by adjusting the height of the baffle, avoiding the blockage caused by the too fast feeding speed of corncobs stacking on each other. By setting four groups of rotating rollers, the orientation of corncobs is adjusted through positive and reverse threads, making the corncobs parallel to the rotating rollers, facilitating the transportation of corncobs, so as to facilitate the cutting of corncobs. By optimizing the auxiliary component, a tool is arranged at the bottom end of the sliding rod, and the sliding rod drives the tool to move up and down, and the tool can cut the corncobs on the fixed plate, making the crushing of corncobs more uniform and improving the crushing efficiency of corncobs.

[0004] However, there are many deficiencies in this furfural raw material processing equipment, such as it cannot efficiently and uniformly crush the furfural raw materials to the required fineness, reducing the production efficiency. Summary of the Utility Model

[0005] Aiming at the above technical deficiencies, the purpose of the present utility model is to provide a furfural raw material crushing and filtering equipment, which can efficiently and uniformly crush the furfural raw materials to the required fineness, improve the production efficiency, prevent the leakage of dust during the crushing process, protect the production environment and the health of operators, accurately control the particle size distribution of products, and ensure that the filtered furfural material meets the quality standards.

[0006] In order to solve the above technical problems, the present utility model provides the following technical solutions:

After the furfural raw material is put in, the cover plate is snap-connected to the top end of the feed pipe to prevent dust leakage. The internal circuit connections of the control device, the motor, the solenoid valve and the electric push rod are all prior arts and will not be elaborated here. The rotation speed of the motor is set through the control device and the motor is started. After the motor is started, it drives the rotating rod to rotate, and the multiple blades on the outer side of the rotating rod rotate accordingly to cut and crush the raw material. At the same time, the scraper at the bottom of the rotating rod rotates along the inner bottom wall of the crushing tank at the bottom of the rotating rod to scrape off the materials adhering to the inner bottom wall of the crushing tank to ensure thorough crushing.

[0016] Preferably, the electric push rod is fixedly connected to the left side of the dust-proof cabinet, and the electric push rod is electrically connected to the control device.

[0017] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

After the furfural raw materials are put in place, snap the cover plate onto the top of the feed pipe to prevent dust leakage. Set the rotation speed of the motor through the control device and start the motor. After the motor starts, drive the rotating rod to rotate, and the multiple blades on the outside of the rotating rod rotate accordingly to cut and crush the raw materials. At the same time, the scraper at the bottom of the rotating rod rotates along the inner bottom wall of the crushing tank at the bottom of the rotating rod to scrape off the materials adhering to the inner bottom wall of the crushing tank, ensuring the thoroughness of crushing. When the crushing reaches the required fineness, the motor can be turned off and the solenoid valve can be opened through the control device, so that the crushed materials are discharged through the discharge pipe under the action of gravity.

[0019] Second, during or after the crushing process, start the electric push rod. The electric push rod pushes the clamping seat and the screen clamped therein to move to the right until the screen is stably matched with the guide block and the limit block. The crushed materials directly fall onto the screen through the discharge pipe. The fine particles pass through the screen and fall into the collection box below, while the larger particles are intercepted by the screen. The screen can be disassembled by turning the bolts for replacement or cleaning to meet the filtering requirements of different particle sizes. After the filtering is completed, close the solenoid valve, open the door panel hinged on the left side of the dust-proof cabinet, and take out the collection box on the inner bottom wall of the dust-proof cabinet for subsequent processing.

[0029] Through the above technical solution, first, the furfural raw materials to be crushed are put into the crushing tank 201 through the feed pipe 206. After the furfural raw materials are put in place, the cover plate 207 is snapped onto the top of the feed pipe 206 to prevent dust leakage. The rotation speed of the motor 205 is set through the control device 101 and the motor 205 is started. After the motor 205 is started, it drives the rotating rod 202 to rotate, and multiple blades 203 on the outer side of the rotating rod 202 rotate accordingly to cut and crush the raw materials. At the same time, the scraper 204 at the bottom of the rotating rod 202 rotates along the inner bottom wall of the crushing tank 201 at the bottom of the rotating rod 202 to scrape off the materials adhering to the inner bottom wall of the crushing tank 201, ensuring the thoroughness of crushing. When the crushing reaches the required fineness, the motor 205 can be turned off through the control device 101 and the solenoid valve 209 can be opened, so that the crushed materials are discharged through the discharge pipe 208 under the action of gravity. The discharged materials fall into the sieve mesh 304, and the furfural raw materials can be efficiently and evenly crushed to the required fineness, improving production efficiency;

And two discharge pipes 208 and solenoid valves 209 are respectively arranged on the left and right sides of the bottom of the crushing tank 201. Such a design can balance the discharge pressure, improve the discharge efficiency, and ensure that the materials can be discharged smoothly.

[0038] Specifically, both the motor 205 and the solenoid valve 209 are electrically connected to the control device 101.
