Description

Technical Field

[0001] This utility model relates to a feeding device for adding silicon to silicon-modified phenolic resin for brake pads under negative pressure, belonging to the field of this invention. Background Technology

[0002] Brake pads, also known as brake discs, are the most critical safety component in a car's braking system. The effectiveness of braking depends entirely on the brake pads.

[0003] Modified phenolic resin is one of the materials used to make brake pads. Due to its excellent heat resistance, wear resistance and mechanical strength, it is widely used in the manufacture of brake pads. In order to improve the performance of modified phenolic resin, additives are usually added to increase its strength. Therefore, in view of the above situation, a feeding device for adding silicon under negative pressure to silicon-modified phenolic resin for brake pads is proposed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a feeding device for adding silicon to silicon-modified phenolic resin for brake pads under negative pressure, so as to solve the existing problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a feeding device for adding silicon to silicon-modified phenolic resin for brake pads under negative pressure, the structure of which includes a reaction vessel, a suction device connected to one side of the reaction vessel, and an air pump provided above the reaction vessel, with a pressure gauge provided on one side of the air pump, the suction device including a material box, a suction nozzle connected below the material box and a connecting pipe connected to the suction nozzle, the connecting pipe communicating with the reaction vessel, and an air valve provided on the connecting pipe. The reaction vessel, air pump and pressure gauge are all conventional general-purpose accessories, so they are not described in detail.

[0006] Furthermore, a gas pipe is provided on one side of the reactor, one end of which is connected to the reactor, and the other end of which extends to the outside of the reactor and is threaded with a sealing head.

[0007] Furthermore, the suction nozzle is a conical suction nozzle.

[0008] Furthermore, the corners of the connecting pipes are designed with a streamlined shape.

[0009] Furthermore, the output shaft of the vacuum pump extends into the reactor and is connected to a filter port. The filter port is provided with a filter layer, which is composed of filter sheets. The filter sheets are wavy and the filter layer is composed of two filter sheets combined together.

[0010] Furthermore, the material bin is provided with a scale bar.

[0011] Furthermore, the trachea is provided with a limiting block, and the sealing head is provided with a locking block. The limiting block blocks the locking block so that the sealing head cannot be removed from the trachea.

[0012] Furthermore, when the sealing head is unscrewed from the air tube, the limiting block will block the locking block, and a gap will be formed between the sealing head and the air tube.

[0013] The beneficial effects of this utility model are:

[0014] 1. Silicon powder is added by using a suction device in conjunction with an air pump to create negative pressure suction.

[0015] 2. The suction nozzle is designed in a conical shape to better suit the characteristics of silicon powder, better adapt to the flow of silicon powder, and improve suction efficiency. The bends in the connecting pipe are designed in a streamlined shape to reduce air resistance and improve the efficiency of airflow, thereby enhancing the stability and efficiency of negative pressure suction.

[0016] 3. It is equipped with a filter port to prevent silicon powder from entering the vacuum pump. The filter layer consists of double filter sheets with a wavy design. This design not only increases the filtration area and improves the filtration efficiency, but also makes the structure more robust and durable.

[0017] 4. The gas pipe and the sealing head are designed together to form a venting assembly for venting the reactor. Limiting blocks and locking blocks are provided to prevent the sealing head from popping out due to negative pressure when it is opened. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figures 1-5 This utility model provides a technical solution for a feeding device for adding silicon to silicon-modified phenolic resin for brake pads under negative pressure: its structure includes a reaction vessel 1, a suction device 2 connected to one side of the reaction vessel 1, and an air pump 3 above the reaction vessel 1. A pressure gauge 4 is provided on one side of the air pump 3. The suction device 2 includes a material box 5, a suction nozzle 6 connected to the bottom of the material box 5, and a connecting pipe 7 connected to the suction nozzle 6. The connecting pipe 7 is connected to the reaction vessel 1, and an air valve 8 is provided on the connecting pipe 7.

[0027] A gas pipe 9 is also provided on one side of the reactor 1. One end of the gas pipe 9 is connected to the reactor 1, and the other end of the gas pipe 9 extends to the outside of the reactor 1 and is threadedly connected to a sealing head 10. The suction nozzle 6 is a conical suction nozzle, and the corner of the connecting pipe 7 is designed with a streamlined shape.

[0028] The output shaft of the vacuum pump 3 extends into the reactor 1 and is connected to a filter port 301. The filter port 301 is provided with a filter layer 302. The filter layer 302 is composed of filter sheets 303. The filter sheets 303 are wavy and the filter layer 302 is composed of two filter sheets 303.

[0029] The material box 5 is provided with a scale bar 501;

[0030] The trachea 9 is provided with a limiting block 901, and the sealing head 10 is provided with a locking block 1001. The limiting block 901 blocks the locking block 1001 so that the sealing head 10 cannot be removed from the trachea 9. When the sealing head 10 is unscrewed from the trachea 9, the limiting block 901 will block the locking block 1001, and a gap 1002 will be formed between the sealing head 10 and the trachea 9.

[0031] For example, during operation, phenolic resin that has been produced in advance is put into reactor 1, silicon powder is added to material box 5, and negative pressure is formed in reactor 1 by working of vacuum pump 3. Then, air valve 8 is opened. Due to the negative pressure formed in reactor 1, silicon powder in material box 5 will be sucked into reactor 1.

[0032] When the work is finished and it is necessary to depressurize the reactor 1, the sealing head 10 can be unscrewed. Since the reactor 1 is still under negative pressure, the sealing head 10 may pop out directly. Therefore, a locking block 1001 is set to lock the limiting block 901, so as to prevent the sealing head 10 from hitting the staff when it pops out. In addition, the gap 1002 between the air pipe 9 and the sealing head 10 will not affect the air flow, thus achieving the function of safe depressurization.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
