[0023] The present utility model provides a device material input channel. Figure 1 This is a specific embodiment of the device material input channel provided by the present utility model.

[0024] As Figure 1 shown, an embodiment of the present utility model provides a device material input channel 100, which includes a device housing 1, a connecting pipe 2, and a material conveying pipe 3. A receiving cavity is provided inside the device housing 1. One side of the device housing 1 protrudes with a feeding part 11, and a communicating cavity is provided inside the feeding part 11. The receiving cavity is communicated with the communicating cavity, and anti-corrosion layers 12 are covered on the inner walls of both the receiving cavity and the communicating cavity. The receiving cavity and the communicating cavity are sealed. The receiving cavity is communicated with the material conveying pipe 3 through the connecting pipe 2. One end of the connecting pipe 2 is connected to the material conveying pipe 3, and the other end penetrates through the communicating cavity and extends into the receiving cavity.

[0025] In the present utility model, a receiving cavity is provided inside the device housing 1 for receiving materials. One side of the device housing 1 protrudes with a feeding part 11, and a communicating cavity is provided inside the feeding part 11. The receiving cavity is communicated with the communicating cavity, and anti-corrosion layers 12 are covered on the inner walls of both the receiving cavity and the communicating cavity to prevent the materials from corroding the device housing 1. The receiving cavity and the communicating cavity are sealed. The receiving cavity is communicated with the material conveying pipe 3 through the connecting pipe 2. One end of the connecting pipe 2 is connected to the material conveying pipe 3, and the other end penetrates through the communicating cavity and extends into the receiving cavity. Materials are input from the material conveying pipe 3, flow through the connecting pipe 2 to the receiving cavity of the device housing 1. Since the solid content of the materials is relatively high, scale will be formed in the pipeline. After the scale gradually accumulates and causes the pipeline to be blocked, the scale needs to be cleaned. Compared with the prior art where the receiving cavity of the device housing 1 is directly communicated with the material conveying pipe 3 through the communicating cavity of the feeding part 11, the scale will accumulate in the communicating cavity, and the anti-corrosion layer 12 will be damaged when cleaning the scale. In this application, the connecting pipe 2 is provided to communicate the receiving cavity and the material conveying pipe 3, and the connecting pipe 2 penetrates through the communicating cavity and extends into the receiving cavity. Even if the pipeline is blocked due to the accumulation of scale, only the connecting pipe 2 needs to be removed to clean the scale, and the anti-corrosion layer 12 will not be damaged, thereby preventing the device housing 1 from being corroded by the materials. The device material input channel 100 and the phosphoric acid chemical industry rubber-lined device provided by the present utility model solve the problem that the existing material input channel has the problem of corrosion of the device pipe orifice caused by the damage of the cleaning anti-corrosion layer.

[0026] It should be noted that the material is phosphoric acid, and the anti-corrosion layer 12 is a rubber-lined rubber sheet, which will not react with the phosphoric acid in the receiving cavity and can protect the device housing 1.

[0027] There is no limitation on the specific structure of the connecting pipe 2, as long as it can connect the accommodating cavity and the material conveying pipe 3. For example, in some embodiments, such as Figure 1 As shown, the connecting pipe 2 includes a main body section 21 and a connecting section 22. The main body section 21 at least partially penetrates the communication cavity and extends into the accommodating cavity, and the main body section 21 is connected to the material conveying pipe 3 through the connecting section 22. With such a setting, the material is input from the material conveying pipe 3, flows through the connecting section 22 and the main body section 21, and finally flows into the accommodating cavity.

[0028] Specifically, the main body section 21 is a stainless steel pipe, and the connecting section 22 is a flange.

[0029] In some embodiments, such as Figure 1 As shown, an inlet is formed at one end of the feeding part 11 facing away from the equipment housing 1. The main body section 21 is provided with a mounting section 23 protruding along its circumferential direction. The mounting section 23 is connected to the feeding part 11 and covers the inlet. With such a setting, on the one hand, the main body section 21 can be fixed on the equipment housing 1 by connecting the mounting section 23 with the feeding part 11. On the other hand, the mounting section 23 covers the inlet, so that the accommodating cavity and the communication cavity are sealed, preventing the material from flowing out of the inlet.

[0030] It should be noted that the main body section 21 is composed of two sections of stainless steel pipes, and the mounting section 23 is a flange. The two sections of stainless steel pipes are connected by the flange and are coaxially arranged.

[0031] Furthermore, there is no limitation on the caliber of the main body section 21, as long as part of the main body section 21 can penetrate the communication cavity and extend into the accommodating cavity. For example, in some embodiments, the main body section 21 penetrating the communication cavity is in close contact with the anti-corrosion layer 12 covered on the inner wall of the communication cavity. Compared with the clearance fit between the main body section 21 and the anti-corrosion layer 12, the close contact setting not only enables the caliber of the main body section 21 to be set to the maximum, at this time the flow rate of the material conveyed by the main body section 21 is the largest, but also the close contact setting can prevent the material from entering the gap between the main body section 21 and the anti-corrosion layer 12, resulting in scale accumulation in the gap.

[0032] There is no restriction on the connection method between the connecting pipe 2 and the material conveying pipe 3, as long as it is ensured that the material is input from the material conveying pipe 3 and flows through the connecting pipe 2 to the accommodating cavity. In some embodiments, the connecting pipe 2 and the material conveying pipe 3 are welded, and the connecting pipe 2 and the feeding part 11 are welded. The welding connection method is simple, which can not only improve the strength of the connection part, but also has good sealing performance, avoiding material leakage during the conveying process.

[0033] Other connection methods can also be adopted between the connecting pipe 2 and the material conveying pipe 3. For example, in some embodiments, the connecting pipe 2 and the material conveying pipe 3 are connected by threads. Since the scale generated by the material will gradually accumulate until the pipeline is blocked, in order to avoid pipeline blockage, the staff needs to regularly remove the connecting pipe 2 to clean the scale. The threaded connection method is more convenient for disassembly and assembly.

[0034] Furthermore, due to the gap at the connection part in the threaded connection method, the material may leak from the gap during the conveying process. In order to improve the sealing performance of the connection part, in some embodiments, a sealing part is provided annularly along the circumferential direction at the connection of the connecting pipe 2 and the material conveying pipe 3. The sealing part is made of elastic material, and part of the sealing part can be inserted into the gap at the connection part, thereby improving the sealing performance of the connection part and avoiding material leakage during the conveying process.

[0035] Since the scale generated by the material will gradually accumulate until the pipeline is blocked, in order to avoid pipeline blockage, the staff generally needs to regularly remove the connecting pipe 2 to clean the scale, and then install the connecting pipe 2 after cleaning. This process is relatively cumbersome. In order to reduce the workload of the staff, in some embodiments, as Figure 1 shown, a cleaning port 24 is provided on one side of the connecting pipe 2 for a cleaning brush head to extend into to clean the scale. The equipment material input channel 100 further includes a cover body 4, and the cover body 4 covers the cleaning port 24. With this setting, when the material conveying stops, the accumulated scale is cleaned by extending the cleaning brush head into the cleaning port 24, avoiding scale blockage. The staff can clean the scale without disassembling and assembling the connecting pipe 2, greatly reducing the workload of the staff.

[0036] Furthermore, since the material will flow through the connecting pipe 2, in order to avoid material leakage during the conveying process, it is necessary to ensure the sealing performance of the connecting pipe 2. Therefore, in some embodiments, part of the cover body 4 is made of elastic material, and the elastic part of the cover body 4 is in interference fit with the cleaning port 24. Through the interference fit between the cover body 4 and the cleaning port 24, it is avoided that the material seeps out from the gap between the cover body 4 and the cleaning port 24 during the conveying process.

[0037] In addition, the present utility model further provides a phosphoric acid chemical industry rubber-lined equipment, including the equipment material input channel 100, the equipment material input channel 100 includes an equipment housing 1, a connecting pipe 2 and a material conveying pipe 3. An accommodating cavity is provided inside the equipment housing 1. One side of the equipment housing 1 is convexly provided with a feeding part 11. A communicating cavity is provided inside the feeding part 11. The accommodating cavity communicates with the communicating cavity, and the inner walls of the accommodating cavity and the communicating cavity are both covered with an anti-corrosion layer 12. The accommodating cavity and the communicating cavity are sealed. The accommodating cavity communicates with the material conveying pipe 3 through the connecting pipe 2. One end of the connecting pipe 2 is connected to the material conveying pipe 3, and the other end penetrates through the communicating cavity and extends into the accommodating cavity.

[0038] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
