[0031] Techniques, methods and equipment known to those skilled in the relevant art can not be discussed in detail, but in appropriate cases, the techniques, methods and equipment should be considered as part of the specification.

[0032] The present application mainly aims at the problems of low automation and integration level, insufficient output and irregular production of catalyst carrier regular forming in the prior art, and provides a catalyst carrier regular forming system and method.

[0033] With reference to Figure 1 and Figure 2 , the present application provides a catalyst carrier regular forming system, comprising: an extruding device for processing catalyst carrier blanks into catalyst carrier strips with a predetermined shape, the extruding device comprising an extruder, an extruding die connected with the output end of the extruder and a forming die sealingly connected with the outlet end of the extruding die; a conveying device for conveying the catalyst carrier strips processed by the extruding device; a fixed-length cutting device for cutting the catalyst carrier strips conveyed by the conveying device into catalyst carrier strip segments with a predetermined length; a row cutting device for cutting the catalyst carrier strip segments into catalyst carrier particles with a predetermined size; and a conveying and pushing device for conveying the catalyst carrier strip segments with a predetermined length on the conveying device to the row cutting device, the conveying and pushing device comprising a pushing plate arranged on one side of the conveying device, a rolling plate 7-2 arranged on the other side of the conveying device and a buffer 7-3 arranged on the rolling plate 7-2; wherein the pushing plate can push the catalyst carrier strip segments with a predetermined length on the conveying device to the rolling plate 7-2, the rolling plate 7-2 is arranged obliquely so as to be able to convey the catalyst carrier strip segments to the row cutting device arranged below the rolling plate 7-2, and the buffer 7-3 is arranged to have a closed state and an open state, when in the closed state, the buffer 7-3 can block the movement of the catalyst carrier strip segments towards the row cutting device, and when in the open state, the buffer 7-3 can make the catalyst carrier strip segments move towards the row cutting device, so that the movement speed of each part of the catalyst carrier strip segments is the same.

[0034] In the present application, the catalyst carrier embryo material is processed into a catalyst carrier strip by the strip extruding device, the catalyst carrier strip processed by the strip extruding device is conveyed by the conveying device, the catalyst carrier strip on the conveying device is cut to a fixed length by the fixed-length cutting device to obtain a catalyst carrier strip segment of a predetermined length, the obtained catalyst carrier strip segment of a predetermined length is pushed to the row cutting device by the strip pushing device, so that the catalyst carrier strip segment of a predetermined length is cut into catalyst carrier particles of a predetermined size, thereby completing the cutting and regular shaping of the catalyst carrier. In the present application, the cooperation among the strip extruding device, the conveying device, the fixed-length cutting device, the strip pushing device and the row cutting device enables the entire catalyst carrier forming process to be continuous and automatic, thereby improving the catalyst carrier forming work efficiency. In addition, the cut catalyst carrier strip segment of a predetermined length is pushed to the strip rolling plate by the pushing plate, the strip rolling plate is inclined, which can reduce the risk that the catalyst carrier strip segment is pushed to the row cutting device at too high a speed and thus the final cutting product has a low qualification rate. Meanwhile, the buffer is arranged on the strip rolling plate, when the buffer is in a closed state, the catalyst carrier strip segment of a predetermined length is blocked from moving towards the row cutting device, so that even if there is a speed difference between the parts of the catalyst carrier strip segment of a predetermined length during the movement of the strip rolling plate, the parts are at the same horizontal line due to the buffer; when the buffer is in an open state, the catalyst carrier strip segment of a predetermined length continues to move towards the row cutting device, since at this time, the parts of the catalyst carrier strip segment of a predetermined length start to move from the same horizontal line and from a stationary state, thereby ensuring that the movement speeds of the parts are the same, and the catalyst carrier particles obtained finally reach the row cutting device at the same time, thereby improving the regularity of the obtained catalyst carrier particles.

[0035] Preferably, the pushing plate can be a long plate, which has a length greater than that of the catalyst carrier strip segment, to ensure that the catalyst carrier strip segment can be pushed to the strip rolling plate 7-2.

[0036] In addition, in some optional embodiments of the present application, the pushing plate can be connected with the rotating shaft, and the catalyst carrier strip segment is pushed from the conveying device to the strip rolling plate 7-2 by rotating clockwise or counterclockwise.

[0037] Alternatively, preferably, one side of the pushing plate is connected with the air cylinder through a push rod, and the catalyst carrier strip segment is pushed from the conveying device to the strip rolling plate 7-2 under the driving of the air cylinder.

When the lifting mechanism is raised, the buffer plate is raised, and the buffer plate is in the open state to allow the catalyst carrier strip segment to move towards the cutting device. When the lifting mechanism is lowered, the bottom of the buffer plate abuts against the rolling plate 7-2, and the buffer plate is in the closed state to block the catalyst carrier strip segment from moving towards the cutting device.

[0039] Alternatively, in some optional embodiments, referring to Figure 2 , the top of the buffer plate is connected to a rope, and one end of the rope is fixedly connected. The buffer plate can swing under the action of gravity of the catalyst carrier strip segment, so that the buffer plate is in the open state to allow the catalyst carrier strip segment to move towards the cutting device. It should be noted that when the rolling plate 7-2 moves towards the cutting device, the catalyst carrier strip segment may have a situation that one end of the catalyst carrier strip segment moves faster than the other end. When the end that moves faster reaches the buffer plate first, the buffer plate is still in the closed state, so the buffer plate can block the end that moves faster from continuing to move towards the cutting device. When the other end that moves slower also reaches the buffer plate, the buffer plate swings under the action of gravity of the catalyst carrier strip segment, so that the buffer plate is in the open state to allow the catalyst carrier strip segment to continue to move towards the cutting device. Through the buffering effect of the buffer plate, the speed difference between the parts of the catalyst carrier strip segment can be reduced, and finally the catalyst carrier strip segment can reach the cutting device at the same time, thereby improving the regularity of the catalyst carrier forming.

[0040] Preferably, a plurality of buffers 7-3 are arranged on the rolling plate 7-2. The plurality of buffers 7-3 can further improve the uniformity of the movement speed of the parts of the catalyst carrier strip segment on the rolling plate 7-2, and finally improve the yield of the product.

[0045] In some alternative embodiments, the cutting device can use a laser cutting device or high-pressure gas to cut the catalyst carrier strip segments into catalyst carrier particles of a predetermined size.

[0046] Alternatively, preferably referring to Figure 2 , the cutting device can include a cutting device 8-3 for cutting the catalyst carrier strip segments into catalyst carrier particles of a predetermined size. The cutting device 8-3 includes a plurality of cutters arranged along the length direction of the catalyst carrier strip segments, and the plurality of cutters cut the catalyst carrier strip segments by rotating.

[0056] Preferably, a cooling unit is arranged in the extrusion die 2 to reduce the temperature in the extrusion die 2. Since the diameter of the extrusion die 2 gradually decreases from the inlet end to the outlet end, the friction force acting on the catalyst carrier blank increases gradually when the catalyst carrier blank moves towards the forming die, resulting in a high temperature in the extrusion die 2. Arranging a cooling unit in the extrusion die 2 is beneficial to reduce the temperature in the extrusion die 2, prevent the evaporation of water in the catalyst carrier blank due to excessive temperature, and ensure that the catalyst carrier blank can be extruded from the forming die to obtain the catalyst carrier strip.
