Description

Technical Field

[0001] This utility model relates to the field of catalyst processing technology, specifically a catalyst calcination device. Background Technology

[0002] A catalyst is generally a substance that increases the reaction rate without changing the total standard Gibbs free energy change of the reaction. It can also be described as a substance that can increase the chemical reaction rate without changing the chemical equilibrium, and whose mass and chemical properties do not change before and after the chemical reaction. Catalysts need to be calcined during processing, so calcination equipment is required.

[0003] The "High-Energy Catalyst Regeneration and Calcination Device" disclosed in publication number "CN217604643U" includes a roller conveyor belt kiln. Multiple pairs of support columns are fixed to both sides of the metal mesh belt in the roller conveyor belt kiln, and a metal support mesh is provided between adjacent pairs of support columns. The support columns are telescopic rods, and both ends of one side of the metal support mesh are hinged to two corresponding support columns on the same side of the metal mesh belt via damping shafts.

[0004] Traditional calcination devices mostly adopt an open structure. The open structure leads to a large amount of heat loss during calcination, resulting in low energy utilization, increased fuel consumption and production costs, and the harmful gases generated during calcination pollute the environment. At the same time, the open structure does not have the function of turning and dispersing the catalyst during calcination, resulting in uneven heating of the catalyst and affecting the calcination quality of the catalyst. To address these issues, we have designed a catalyst calcination device. Utility Model Content

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a catalyst calcination device, comprising a calcination mechanism and a closing mechanism assembled on one side of the calcination mechanism;

[0007] The calcination mechanism includes a main frame, a calcination tank is rotatably installed inside the main frame, and a rotary motor with its output end connected to the calcination tank is fixedly installed on one side of the main frame.

A gas pipe is fixedly installed at the center of the outer side of the rotating disk. One end of the gas pipe extends into the calcining tank and is fixedly installed with combustion nozzles at equal intervals. A stirring frame is fixedly installed on the lower inner side of the rotating disk. Shovel plates are fixedly installed at equal intervals around the inner perimeter of the closing cover.

[0009] Preferably, a discharge port is provided on the outer side of the closed cover, and a closing column is installed inside the discharge port.

[0011] Preferably, a wheel seat is fixedly installed on one side of the main frame, and a support wheel is rotatably installed inside the wheel seat. A wheel ring that cooperates with the support wheel is fixedly installed on the outer wall of the calcining tank.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] Please see Figure 2-5 As shown, this embodiment proposes a catalyst calcination device, including a calcination mechanism 1 and a closing mechanism 2 assembled on one side of the calcination mechanism 1. The calcination mechanism 1 includes a main frame 102, and a calcination tank 101 is rotatably installed inside the main frame 102. A rotary motor 103 with its output end connected to the calcination tank 101 is fixedly installed on one side of the main frame 102. The closing mechanism 2 includes a closing cover 201 and a fixing seat 303. A rotating disk 202 is rotatably installed at the center of the closing cover 201. A raw material pipe 204 is fixedly installed on the upper outer side of the rotating disk 202. One end of the raw material pipe 204 extends into the interior of the calcination tank 101. A gas pipe 203 is fixedly installed at the center of the outer side of the rotating disk 202. One end of the gas pipe 203 extends into the interior of the calcination tank 101 and combustion nozzles 207 are fixedly installed at equal intervals.

[0025] In use, the main frame 102 rotates the calcining tank 101, which stores the catalyst to be calcined. The rotary motor 103 drives the calcining tank 101 to rotate. The closing cover 201 seals one side of the calcining tank 101 and rotates with it. Closing the calcining tank 101 reduces heat loss during operation, improving the energy efficiency of the device. Furthermore, closing the calcining tank 101 prevents harmful gases generated during operation from entering the air, enhancing the safety of the device during operation. The rotating disk 202 is installed inside the turntable 202. The rotating disk 202 can remain stationary when the closed cover 201 is rotated. The raw material pipe 204 installed on the upper outer side of the rotating disk 202 can inject catalyst raw materials into the calcination tank 101, thereby facilitating the calcination operation of the catalyst and improving the convenience of feeding the device. The gas pipe 203 is connected to the external gas supply pipeline, and the gas can be burned through the combustion nozzle installed at the bottom of the gas pipe 203. The combustion can heat the catalyst inside the calcination tank 101, realizing the function of calcining the catalyst. Example 2

[0026] Based on Example 1, such as Figure 5 As shown, an agitator 401 is fixedly installed on the lower inner side of the rotating disk 202, and shovel plates 4 are fixedly installed at equal intervals around the inner side of the closed cover 201.

[0027] During use, the stirring frame 401 and the rotating disk 202 remain stationary, so that when the calcining tank 101 rotates, the stirring frame 401 can disperse the catalyst inside, avoiding the formation of catalyst clumps inside the calcining tank 101. The shovel plate 4 rotates with the calcining tank 101 to turn the catalyst inside. Turning the catalyst improves the uniformity of heating by the flame of the combustion nozzle 207. Dispersing and turning the catalyst can accelerate the calcination speed and improve the calcination efficiency of the device.

[0028] like Figure 5 As shown, a discharge port 208 is provided on the outside of the closed cover 201, and a closing column 205 is installed inside the discharge port 208.

[0029] When in use, closing the cover 201 and rotating the discharge port 208 downwards allows the catalyst to be discharged after calcination, improving the convenience of discharging the catalyst after calcination. The closing column 205 can be inserted into the discharge port 208 to block and close the device during operation, thereby ensuring the stability of the device during catalyst calcination.

[0030] like Figure 5As shown, a support frame 3 is slidably mounted on one side of the fixed base 303 via a slide rod 302. The top of the support frame 3 is fixedly connected to the outside of the closed cover 201. A hydraulic cylinder 301 with its output end connected to the support frame 3 is fixedly mounted on the top of the fixed base 303. A discharge plate 304 is fixedly mounted on the upper part of the inside of the support frame 3.

[0031] In use, the support frame 3 can support the closed cover 201, and the closed cover 201 can be pushed by the extension of the hydraulic cylinder 301. The movement of the closed cover 201 can open one side of the calcining tank 101, which facilitates the staff to inspect and maintain the interior of the calcining tank 101 later. The fixed seat 303 can be fixed at the bottom of the support frame 3. The sliding rod 302 increases the stability when the fixed seat 303 is connected to the support frame 3. The discharge plate 304 can guide the catalyst discharged from the discharge port 208 to be discharged.

[0032] like Figure 2 and Figure 5 As shown, a wheel seat 104 is fixedly installed on one side of the main frame 102, and a support wheel 105 is rotatably installed inside the wheel seat 104. A wheel ring 106 that works with the support wheel 105 is fixedly installed on the outer wall of the calcining tank 101.

[0033] In use, the support wheel 105 inside the wheel seat 104 is in rolling connection with the wheel ring 106, so that the support wheel 105 and the wheel ring 106 can provide rolling support for one side of the calcining tank 101, increasing the stability of the calcining tank 101 during rotation.

[0034] like Figure 3 and Figure 4 As shown, docking pins 108 are fixedly installed at equal intervals on one side of the calcining tank 101, and docking sleeves 206 that cooperate with docking pins 108 are fixedly installed around the inner side of the closed cover 201.

[0035] In use, when the closing cover 201 closes to the calcining tank 101, the connecting pin 108 is inserted into the inside of the connecting sleeve 206, thereby allowing the closing cover 201 and the calcining tank 101 to be rotated and bound together, so that the calcining tank 101 can drive the closing cover 201 to rotate.

[0036] like Figure 3 As shown, the interior of the calcining tank 101 is provided with a heat insulation layer 107.

[0037] When in use, the insulation layer 107 can provide heat insulation for the interior of the calcining tank 101, reduce the loss of heat inside the calcining tank 101, and prevent the internal heat from being conducted to the outer wall of the calcining tank 101 and causing high temperature.

[0038] Working principle: The calcining tank 101 is closed by the closed cover 201. The gas pipe 203 and the combustion nozzle 207 heat and calcine the catalyst in the calcining tank 101 through the flame. Closing the calcining tank 101 can reduce heat loss, improve heat utilization, and reduce processing costs. The rotary motor 103 drives the calcining tank 101 to rotate. During the rotation of the calcining tank 101, the stirring frame 401 and the shovel plate 4 can disperse and turn the catalyst, thereby improving the uniformity of the flame heating and calcination of the catalyst and improving the quality of catalyst calcination by the device.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
