[0002] SCR catalyst blanks refer to the materials in the initial shape formed in the process of producing selective catalytic reduction denitrification catalysts. These blanks are usually made through molding processes such as extrusion or pressing, and then undergo subsequent processing steps such as drying and calcination to form the final catalyst product. Catalysts are key materials used to reduce nitrogen oxide emissions generated during combustion and are widely used in thermal power plants, industrial boilers, automobile exhaust treatment and other fields.

[0003] In the production process of catalyst, extrusion molding is an important step. The catalyst blank after extrusion needs to be properly stored and transported to ensure its quality while sending the blank to other processing stations. The existing SCR catalyst extrusion blank storage and transportation devices are mostly composed of frame installations. During the extrusion blank transportation process of the catalyst, the catalyst may be affected by dust, moisture or other pollutants, which may change the chemical composition and structure of the catalyst and reduce its activity. The catalyst is very sensitive to humidity and temperature. If the storage and transportation device cannot control the storage environment of the blank, it may cause the catalyst performance to decline and increase the blank scrap rate.

[0004] Furthermore, if a completely enclosed transfer device is used for transfer, the operator cannot observe the internal situation of the transfer device at any time during the transfer process. During the transfer process, the container containing the blank may be dislocated from the fixed position due to vibration and jolt, affecting the normal transfer work and causing the blank in the container to be scrapped.

This device includes a tray assembly 100, which includes a material support plate 101, mounting shells 102 located on both sides at the same end of the material support plate 101, and a movable cavity 103 located inside the mounting shells 102; a limiting assembly 200, which includes a bracket 201 provided at the bottom of the material support plate 101. A lifting block 202 and a limiting block 203 are provided at the end of the bracket 201. Placing grooves 204 are provided at the tops of both the lifting block 202 and the limiting block 203. The material support plate 101 and the mounting shells 102 form a rectangular plate-like structure, and the four corners of the overall plate-like structure are respectively located in the placing grooves 204. Among them, the side where the mounting shell 102 is provided is located in the placing groove 204 of the lifting block 202. An annular iron 101a is provided at the bottom of the material support plate 101. A positive magnetic strip group 202a and a negative magnetic strip group 202b are provided inside the placing groove 204 at the top of the lifting block 202. The overall bracket 201 is in an X shape, and a magnetic ring 201a adapted to the annular iron 101a is provided on the top surface thereof.

[0038] During use, first place the extruded blank on the surface of the material supporting plate 101, and then place the material supporting plate 101 with the extruded ingredients in the placement groove 205 formed on the surfaces of the limit clamping block 203 and the lifting clamping block 202. During the placement process, the annular iron 101a at the bottom of the material supporting plate 101 is attracted by the magnetic ring 202a on the surface of the bracket 201. The magnetic ring 202a always attracts the material supporting plate 101 with the annular iron 101a at the bottom close to the bracket 201 to fix the position of the material supporting plate 101, ensuring that the position of the material supporting plate 101 is fixed each time it is placed, and reducing the shaking of the material supporting plate 101 caused by external factors under the adsorption of the magnetic ring 202a to prevent it from leaving the required position.

[0039] Embodiment 2

[0040] Refer to Figure 3 、 4 5 is the second embodiment of the present invention. Based on the previous embodiment, this embodiment further includes a sliding component 300, which includes a slider 301, a connecting seat 302 provided on the top of the slider 301. The slider 301 is arranged inside the moving cavity 103. One side of the bottom of the slider 301 is provided with a magnetic sheet 301b, and the magnetism of the magnetic sheet 301b is the same as that of the positive magnetic strip group 202a. The positive magnetic strip group 202a and the negative magnetic strip group 202b are respectively arranged on both sides of the placement groove 204. Among them, the top of the guiding groove 103a close to one side of the positive magnetic strip group 202a is provided with an upward mountain-shaped extension part, and the guiding groove 103a close to the other side of the negative magnetic strip group 202b is provided with a downward extension part.

One side of the slider 301 close to the guiding groove 103a is provided with guiding protrusions 301a.

[0041] During use, when the operator needs to remove the material supporting plate 101, the operator pulls the pull rope 302a. When the pull rope 302a is pulled, it drives the slider 301 to move in the moving cavity 103. The guiding protrusions 301a on both sides of the slider 301 move along the guiding groove 103a. During the movement, the slider 301 gradually approaches the positive magnetic strip group 202a, and a repulsive force is generated between the magnetic sheet 301b at the bottom of the slider 301 and the positive magnetic strip group 202a. The slider 301 is pushed upward under the action of the repulsive force. The guiding protrusions 301a on both sides of the slider 301 enter the upward extension part of the guiding groove 103a during the movement. At the same time, under the action of the repulsive force, the mounting shell 102 and the material supporting plate 101 connected to the mounting shell 102 are always pushed upward to generate a gap between the lifting clamping block 202, and at this time, the guiding protrusions 301a on both sides of the slider 301 are located in the upward extension part of the guiding groove 103a to fix the current position of the slider 301.

[0042] The remaining structure is the same as that of Embodiment 1.

[0043] Embodiment 3

[0044] Refer to Figures 6 to 10 This is the third embodiment of the present utility model. Based on the tray mechanism proposed in Embodiment 1 and Embodiment 2, an extrusion blank storage and transfer device for a catalyst including the above tray mechanism is further provided, which includes a box body mechanism 400, including a box body 401 provided outside the lifting block 202 and the limiting block 203. A universal wheel 402 is provided at the bottom of the box body 401, a hinge 403 is provided on the side surface of the box body 401, an operation panel 404 is provided on the surface of the box body 401, and a sealing door 405 is provided at the other end of the hinge 403; a humidity preservation component 500, including a liquid box 501 provided inside the box body 401 and a liquid pump 502 provided on the outer surface of the box body 401; there are two liquid pumps 502 respectively provided on both sides of the box body 401 and communicated with the liquid pump 502 through the surface of the box body 401. An infusion tube 502a is provided at the output end of the liquid pump 502, and the end of the infusion tube 502a extends into the box body 401. A drain tube 502b is provided at the end of the infusion tube 502a. A placement box 502c is provided on one side of the inner wall of the box body 401 close to the drain tube 502b. A sponge material 502d is provided between the inside of the placement box 502c and the drain tube 502b. An insurance reed 405a is provided on the side of the sealing door 405 close to the box body 401. The insurance reed 405a is composed of two horizontally arranged connecting pieces and a G-shaped blocking piece provided at the ends of the two connecting pieces, and is made of non-magnetic metal material as a whole. A heat preservation component 600, including a storage battery 601 provided inside the box body 401 and a connecting wire 602 provided at the output end of the storage battery 601. The connecting wire 602 extends to the end near the placement box 502c and is provided with a heating shell 603 connected to the placement box 502c. A heating wire 603a is provided horizontally inside the heating shell 603.

[0045] During use, the operator selects the required temperature and humidity through the operation panel 404. Subsequently, the operation panel 404 transmits an electrical signal to the liquid pump 502 and the storage battery 601. After receiving the signal, the liquid pump 502 starts to send the liquid in the liquid tank 501 through the infusion tube 502a into the drain tube 502b and discharges it outward into the sponge material 502d. At the same time, the storage battery 601 starts and connects the heating wire 603a through the connection wire 602 to heat up the heating wire 603a. After the temperature of the heating wire 603a rises, while increasing the temperature inside the box body 401, it transfers the temperature to the sponge material 502d, causing the liquid in the sponge material 502d to evaporate. The evaporated liquid increases the internal humidity inside the box body 401;

[0046] During the process of the operator closing the box body 401 with the closing door 405, the safety spring piece 405a on the surface of the closing door 405 first contacts the lifting block 202 and deforms under the push of the closing door 405, enabling the safety spring piece 405a to deform upward through the lifting block 202 and move to the top of the mounting shell 102 to contact the connecting seat 302 extending outside the mounting shell 102 and push the connecting seat 302 to move. During the movement of the connecting seat 302, it approaches the negative magnetic strip group 202b and adsorbs to each other, ensuring that when the operator does not manually move the slider 301, the slider 301 can still adsorb to the negative magnetic strip group 202b to ensure that the material supporting plate 101 is completely fixed. When opening the closing door 405, the inclined part at the bottom of the safety spring piece 405a can ensure that the safety spring piece 405a deforms under the pulling force of the closing door 405 and smoothly leaves the mounting shell 102.

[0047] The remaining structures are the same as those of Embodiment 2 and Embodiment 1.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
