Description

Technical Field

[0001] This utility model relates to the field of catalyst discharge technology, and in particular to a catalyst finished product discharge device. Background Technology

[0002] Ethylene glycol hydrogenation catalysts are widely used in the chemical industry. They are primarily used to convert ethylene glycol into ethanol or other valuable compounds. These catalysts accelerate the hydrogenation reaction between ethylene glycol and hydrogen, reducing the carbon-oxygen double bonds in the ethylene glycol molecule to produce ethanol. This is the core function of the catalyst in chemical production. By using ethylene glycol hydrogenation catalysts, reaction temperature and pressure can be significantly reduced, and the reaction rate accelerated, thereby improving production efficiency. In some cases, ethylene glycol hydrogenation catalysts can also improve the UV value of the product, bringing it to polyester grade and increasing its added value. For example, certain specific catalysts (such as nickel or nickel compounds supported on alumina-magnesium oxide composite oxide treated with acidic steam) can significantly improve the UV value of ethylene glycol products.

[0003] Ethylene glycol hydrogenation catalysts are generally produced in tablet form. Tablet catalysts have a large specific surface area, which can provide more catalytic active sites, thereby accelerating the hydrogenation reaction between ethylene glycol and hydrogen. Therefore, after the production of ethylene glycol hydrogenation catalysts, they need to be shaped into tablets. In the shaping process, the output material after tableting is more dispersed and inconvenient to collect.

[0004] A separation and pulverizing device and catalyst production equipment disclosed in Chinese patent document CN209318132U, has a dust removal and filtration mechanism connected at one end to a separation mechanism and at the other end to a crushing mechanism. The separation mechanism separates the shaped catalyst, catalyst semi-finished product, and powder, while the crushing mechanism crushes the powder and catalyst semi-finished product. The dust removal and filtration mechanism collects the powder generated by the separation and crushing mechanisms. This addresses the problem of low utilization rate and poor economic efficiency of the semi-finished product and powder generated during catalyst granulation. However, this separation and pulverizing device and catalyst production equipment does not collect the produced catalyst particles, leading to easy waste and increased loss of catalyst particles during discharge. Furthermore, the catalyst is easily broken during discharge, resulting in increased catalyst dust.

[0005] To address the shortcomings of the existing technology, providing a novel catalyst product discharge device is a problem worthy of research. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a catalyst finished product discharge device, which effectively solves the deficiencies of the prior art.

[0007] The purpose of this utility model is achieved through the following technical solution: a catalyst finished product discharge device, including a catalyst forming machine, a catalyst discharge port is provided on one side of the catalyst discharge machine, a limiting discharge channel is assembled and connected to the end of the catalyst discharge port, a groove is opened on the bottom surface of the end of the limiting discharge channel, and a buffer cloth is fixedly connected to the inner wall of the end of the limiting discharge channel.

[0008] Optionally, the inner wall shape of the limiting discharge channel is adapted to the outer wall shape of the catalyst discharge port. Several threaded holes are provided at the top of the connection between the catalyst discharge port and the limiting discharge channel. The catalyst discharge port and the limiting discharge channel are fixedly connected by threaded holes and bolts. The end of the limiting discharge channel is in a vertical state.

[0009] The above technical solution involves assembling a limiting outlet at the end of the catalyst outlet. The vertical part of the limiting outlet can limit and intercept the discharged catalyst particles, ensuring that the discharged catalyst particles fall vertically along the groove, facilitating their collection. This avoids the situation where the discharged catalyst particles fly far away along the catalyst outlet and are difficult to collect. Furthermore, the catalyst discharge device can be selected for installation as needed; it can be installed at the end of the existing catalyst outlet to achieve the desired effect without altering the structure of the original outlet.

[0010] Optionally, clamping parts are fixedly connected to the outer side of the slot and one side of the top of the limiting discharge channel. A cloth groove is opened on one side of the top of the limiting discharge channel. The buffer cloth passes through the cloth groove and its two ends are clamped and fixed by two clamping parts respectively.

[0011] The above technical solution involves setting two clamping parts at the end of the limiting discharge channel, which can clamp and fix the buffer cloth to the inner wall of the end of the limiting discharge channel. The inner side of the buffer cloth is not in contact with the inner wall of the limiting discharge channel. When the catalyst particles are discharged, the buffer cloth can buffer and intercept the flying catalyst particles, allowing them to fall vertically from the slot to complete the discharge collection. The buffer cloth can prevent the catalyst particles from hitting the inner wall of the limiting discharge channel when they fly out, causing them to break and affecting product quality, and can also reduce the noise generated during discharge.

[0012] Optionally, the bottom of the inner wall of the limiting discharge channel is provided with a connecting slope, and the top of the connecting slope is aligned with the bottom of the inner wall of the catalyst discharge port.

[0013] The above technical solution allows for smoother rolling of catalyst particles during discharge by setting a connecting inclined surface at the bottom of the inner wall of the limiting discharge channel. This prevents the catalyst particles from breaking due to height differences during their entry into the limiting discharge channel from the catalyst outlet. Furthermore, the connecting inclined surface plays a positioning role when it aligns with the bottom of the catalyst outlet, enabling quick alignment of the threaded holes on the catalyst outlet and the limiting discharge channel. This facilitates bolt installation and improves the assembly speed of the catalyst discharge device.

[0014] Optionally, the included angle at the top of the end of the limiting discharge channel is set to an arc shape, and a buffer sponge is provided on the inner side of the arc surface of the limiting discharge channel.

[0015] The above technical solution is adopted: by setting the included angle of the end of the limiting discharge channel to an arc shape, the process of intercepting and guiding the catalyst particles to fall is made smoother, thereby improving the integrity rate of the catalyst particles.

[0016] Optionally, a dust extraction fan is provided at the top of the limiting discharge channel, with the dust extraction port of the dust extraction fan facing the inside of the limiting discharge channel.

[0017] The above technical solution involves installing a dust removal fan at the top of the limiting discharge channel to remove dust from the produced catalyst particles, thus preventing dust from affecting the quality of the catalyst product. The collected dust can also be recycled to reduce losses during catalyst production.

[0018] Positive and beneficial effects: 1. The catalyst finished product discharge device, by assembling a limiting discharge port at the end of the catalyst discharge port, can limit and intercept the discharged catalyst particles by installing the vertical part at the end of the limiting discharge port, so that the discharged catalyst particles fall vertically along the groove, which is convenient for collecting the catalyst particles and avoids the situation where the discharged catalyst particles fly far away along the catalyst discharge port and are inconvenient to collect. Moreover, the catalyst discharge device can be selected as needed and can be installed at the end of the original catalyst discharge port to achieve the effect without changing the structure of the original discharge port.

[0019] 2. The catalyst finished product discharge device has two clamping parts at the end of the limiting discharge channel, which can clamp and fix the buffer cloth to the inner wall of the end of the limiting discharge channel. The inner side of the buffer cloth is not in contact with the inner wall of the limiting discharge channel. When the catalyst particles are discharged, the buffer cloth can buffer and intercept the flying catalyst particles, so that they fall vertically from the slot to complete the discharge collection. The buffer cloth can prevent the catalyst particles from hitting the inner wall of the limiting discharge channel when they fly out, causing them to break and affect the product quality. It can also reduce the noise generated during discharge.

[0020] 3. The catalyst finished product discharge device, by setting a connecting slope at the bottom of the inner wall of the limiting discharge channel, can make the rolling of catalyst particles smoother during discharge, avoiding the phenomenon of catalyst particles breaking due to height difference during the process of catalyst particles entering the limiting discharge channel from the catalyst discharge port. In addition, the connecting slope can play a positioning role when it is connected to the bottom of the catalyst discharge port, so that the threaded hole on the catalyst discharge port and the limiting discharge channel can be quickly aligned, which facilitates bolt installation and improves the assembly speed of the catalyst discharge device.

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] Example 1

[0030] like Figures 1 to 4As shown, a catalyst finished product discharge device includes a catalyst forming machine 1, a catalyst discharge port 2 is provided on one side of the catalyst discharge machine 1, and a limiting discharge channel 3 is assembled and connected to the end of the catalyst discharge port 2. A groove 4 is opened on the bottom surface of the end of the limiting discharge channel 3, and a buffer cloth 5 is fixedly connected to the inner wall of the end of the limiting discharge channel 3.

[0031] like Figures 1 to 4 As shown, the inner wall shape of the limiting discharge channel 3 is adapted to the outer wall shape of the catalyst discharge port 2. Several threaded holes 6 are opened at the top of the connection between the catalyst discharge port 2 and the limiting discharge channel 3. The catalyst discharge port 2 and the limiting discharge channel 3 are fixedly connected by the threaded holes 6 and bolts. The end of the limiting discharge channel 3 is in a vertical state. By installing the limiting discharge port 3 at the end of the catalyst discharge port 2, the vertical part at the end of the limiting discharge port 3 can limit and intercept the discharged catalyst particles, so that the discharged catalyst particles fall vertically along the slot 4, which is convenient for collecting the catalyst particles and avoids the situation where the discharged catalyst particles fly far away along the catalyst discharge port 2 and are inconvenient to collect. Moreover, the catalyst discharge device can be selected whether to install it as needed. It can be installed at the end of the original catalyst discharge port 2 to achieve the effect without changing the structure of the original discharge port 2.

[0032] like Figures 2 to 4 As shown, clamping parts 7 are fixedly connected to the outer side of the slot 4 and one side of the top of the limiting discharge channel 3. A cloth groove 8 is opened on one side of the top of the limiting discharge channel 3. The buffer cloth 5 passes through the cloth groove 8, and its two ends are clamped and fixed by two clamping parts 7 respectively. By setting two clamping parts 7 at the end of the limiting discharge channel 3, the buffer cloth 5 can be clamped and fixed to the inner wall of the end of the limiting discharge channel 3. The inner side of the buffer cloth 5 does not fit with the inner wall of the limiting discharge channel 3. When the catalyst particles are discharged, the buffer cloth 5 can buffer and intercept the flying catalyst particles, so that they fall vertically from the slot 4 to complete the discharge collection. The buffer cloth 5 can prevent the catalyst particles from hitting the inner wall of the limiting discharge channel 3 when they fly out, causing them to break and affect the product quality. It can also reduce the noise generated by the discharge.

[0033] like Figure 4 As shown, a connecting slope 9 is provided at the bottom of the inner wall of the limiting discharge channel 3. The top of the connecting slope 9 is aligned with the bottom of the inner wall of the catalyst discharge port 2. By providing the connecting slope 9 at the bottom of the inner wall of the limiting discharge channel 3, the rolling of the catalyst particles during discharge can be smoother, avoiding the situation where there is a height difference in the catalyst particles as they enter the limiting discharge channel 3 from the catalyst discharge port 2, which could lead to breakage of the catalyst particles. In addition, the connecting slope 9 can play a positioning role when it is connected to the bottom of the catalyst discharge port 2, so that the threaded hole 6 on the catalyst discharge port 2 and the limiting discharge channel 3 can be quickly aligned, which facilitates bolt installation and improves the assembly speed of the catalyst discharge device.

[0034] Example 2

[0035] like Figures 5 to 6 As shown, the included angle at the top of the end of the limiting discharge channel 3 is set in an arc shape, and a buffer sponge is provided on the inner side of the arc surface of the limiting discharge channel 3. By setting the included angle at the end of the limiting discharge channel 3 in an arc shape, the process of intercepting and guiding the catalyst particles to fall is made smoother, thereby improving the integrity rate of the catalyst particles.

[0036] like Figure 6 As shown, a dust extraction fan 10 is installed at the top of the limiting discharge channel 3. The dust extraction port of the dust extraction fan 10 faces the inside of the limiting discharge channel 3. By installing the dust extraction fan 10 at the top of the limiting discharge channel 3, the dust can be removed from the finished catalyst particles, avoiding dust from affecting the quality of the catalyst product. The collected dust can be recycled to reduce the loss in catalyst production.

[0037] The working principle of this utility model is as follows:

[0038] S1. The limiting discharge channel 3 is assembled at the end of the catalyst discharge port 2 and fixed by bolts passing through the threaded hole 6.

[0039] S2. The buffer cloth is clamped and fixed between the two clamping parts 7. When the catalyst particles are discharged, the buffer cloth can buffer and guide the discharged catalyst particles.
