Description

Technical Field

[0001] The invention relates to the technical field of spherical catalyst carrier drying, in particular to a drying device and method for spherical catalyst carriers after rounding. Background Art

[0002] Spherical catalyst carriers are basic materials for carrying active catalytic components. Their main function is to provide a larger contact area for the active catalytic components to improve the overall physical stability and catalytic efficiency of the catalyst. Spheronization is a method suitable for preparing spherical catalyst carriers.

[0003] In the prior art, the spherical catalyst carrier after rounding needs to be placed in a material tray first, and then the material tray is placed on a support frame in an oven, and the spherical catalyst carrier is subjected to hot air drying in the oven to remove excess moisture and other volatile substances inside it, thereby ensuring the physical stability and load-bearing performance of the spherical catalyst carrier.

[0004] However, the conventional method of drying the spherical catalyst carrier after rolling and forming in an oven has the following problems: 1. In the prior art, the spherical catalyst carrier is usually placed in a material tray in the form of a multi-layer stack. Due to the limitation of the stacking form, the internal spherical catalyst carrier is difficult to be directly exposed to the hot air circulation path in the oven, resulting in heat transfer mainly relying on indirect conduction between the spherical catalyst carriers. This non-uniform indirect drying method makes the drying rate of the internal spherical catalyst carrier significantly lag behind that of the surface spherical catalyst carrier, which not only leads to the overall drying process of the spherical catalyst carrier The drying time is long and the drying efficiency is low. The low heat conduction efficiency also leads to high heat energy consumption and low energy utilization rate for the overall drying of the spherical catalyst carrier, which in turn leads to high total energy consumption cost for production and processing; 2. In the prior art, the material trays need to be placed layer by layer from bottom to top on the support frame in the oven. When the operator takes and places the material trays close to the top layer, the material trays are more likely to fall accidentally from a height due to insufficient positioning stability or uneven handling force. This situation is more likely to occur in frequent loading and unloading or dense stacking scenarios, which significantly increases the probability of operators encountering production safety accidents.

[0037] See also Figure 2 and Figure 4 The lifting drive unit 24 includes a sliding seat fixedly arranged at the front end of the opposite side of the upper and lower adjacent lifting slides 222, and the sliding seat is composed of a front-to-back symmetrical support two, which is symmetrically fixed on the corresponding lifting slide 222. A sliding block 242 that moves forward and backward is slidably arranged on the left-right symmetrical guide rod three 241, wherein a threaded rod two 243 located between the corresponding guide rod three 241 and threadedly connected to the corresponding sliding block 242 is rotatably arranged on the lower front-to-back symmetrical support two, and a follower that cooperates with the external rotation drive is fixedly arranged at the front end of the threaded rod two 243, and a fixed block 244 is fixedly arranged at the rear end of the opposite side of the upper and lower symmetrical lifting slides 222, wherein the upper fixed block 244 and the lower sliding block 242 are connected by a hinged transmission rod one, and the lower fixed block 244 and the upper sliding block 242 are connected by a left-right symmetrically hinged transmission rod two, and the transmission rod one is hinged to the middle part of the left-right symmetrical transmission rod two.

[0038] The follower is driven to rotate in a directional manner through an external rotation drive, and the follower then drives the corresponding threaded rod 243 to rotate synchronously. The threaded rod 243 then drives the corresponding sliding block 242 to move backward along the guide rod 3 241 through the spiral transmission.

At the same time, the sliding block 242 on the lower side of the lifting slide 222 also moves backward synchronously with the cooperation of the transmission rod 2 and the transmission rod 1, thereby driving the corresponding lifting slide 222 and the corresponding circular support bracket 221 to move upward synchronously through the transmission rod 1 and the transmission rod 2.

[0039] See also Figure 1 and Figure 2 The material turning mechanism 3 includes a protective cover 31 fixedly arranged on the rear side of the oven 1, and a material turning driving part 32 is arranged on the protective cover 31 and cooperates with the docking transmission part 23 for transmission. A material tray 33 is supported in the round-shaped support frame 221, and a docking material turning part 34 is arranged on the material tray 33 and cooperates with the docking transmission part 23 for transmission.

[0040] When the material tray 33 is to be placed, the first material tray 33 is first placed in the uppermost circular support bracket 221 which is below the safe height, and then the corresponding transmission rod 1 and transmission rod 2 are driven by external rotation to drive the uppermost circular support bracket 221 to move upward to the maximum distance, and then the second material tray 33 is placed in the lower circular support bracket 221, and the corresponding transmission rod 1 and transmission rod 2 on the lower side of the lifting slide 222 of the circular support bracket 221 are driven by external rotation again to move upward to the maximum distance, and the circular support brackets 221 on the upper side of the circular support bracket 221 also move upward by the same distance, and the above operation is repeated until the upper material tray 33 is also placed in the lowermost circular support bracket 221.

[0041] When the material tray 33 is to be removed, the material tray 33 in the lowest level circular support frame 221 is first taken out, and then the height of the corresponding circular support frame 221 and the material tray 33 therein are lowered layer by layer from bottom to top, so as to achieve the removal of the material tray 33 in the corresponding circular support frame 221 layer by layer below the safe height.

[0042] The above-mentioned operation method can realize the independent lifting and lowering of each layer of the circular support frame 221 and the material tray 33 placed inside it, so that the height of each layer of the material tray 33 can be adjusted layer by layer. Therefore, when the material tray 33 is taken and placed, it can be ensured that the taking and placing height of the corresponding material tray 33 is always stably maintained below the safe height, thereby fundamentally avoiding the risk of the material tray 33 close to the top layer falling from a height due to unstable positioning or improper operation in the traditional stacking method.

[0043] See also Figure 2 and Figure 3The material turning drive unit 32 includes a motor 321 fixedly arranged on the front side of the protective cover 31, and a pulley 322 is fixedly arranged on the driving end of the motor 321. The front side of the protective cover 31 is also evenly rotated up and down by a rotating shaft located below the motor 321, and is provided with a plurality of pulleys 322 that are driven and matched with the pulleys 322 on the driving end of the motor 321 through belts. All the pulleys 322 correspond to the docking seats 232 one by one, and a docking plug-in 323 that is plugged and matched with the docking slot on the corresponding docking seat 232 is fixedly arranged on the front side of the pulley 322.

[0044] See also Figure 1 and Figure 5 The docking and turning part 34 includes a plurality of groups of linear grooves that are evenly opened on the material tray 33 and pass through from top to bottom, each group is composed of symmetrical linear grooves, a sliding shaft that moves forward and backward is slidably arranged in the linear groove, a turning piece 341 is fixedly arranged on the upper ends of the symmetrical sliding shafts, a connecting plate is fixedly arranged on the lower ends of all the sliding shafts, and a plurality of transmission plug-ins 342 that are plugged in and matched with the transmission sleeve 234 are evenly fixedly arranged on the lower side of the connecting plate; the turning piece 341 is symmetrically opened with arc surfaces for scooping up the spherical catalyst carrier in the material tray 33, and the turning piece 341 is symmetrically opened on the left and right sides of the arc surface with inclined surfaces for turning the scooped spherical catalyst carrier to both sides for material distribution, and a plurality of balls are evenly rolled on the lower side of the turning piece 341.

[0045] When the material tray 33 is placed on the corresponding circular support frame 221, the transmission plug-in 342 on the lower side of the connecting plate is connected and inserted into the corresponding transmission sleeve 234 on the corresponding transmission slide 233; when the movable frame 21 is stably positioned in the oven 1 by the pin 41, the docking slot in the docking seat 232 on the threaded rod 231 is connected and connected with the docking plug-in 323 on the corresponding pulley 322.

[0046] In the process of hot air drying of the spherical catalyst carrier in the material tray 33 by the oven 1, the motor 321 is controlled by the integrated control panel 12 to rotate intermittently in forward and reverse directions, and the motor 321 drives the corresponding pulley 322 to rotate intermittently in forward and reverse directions regularly, and the other pulleys 322 rotate synchronously under the transmission action of the belt, and the pulley 322 drives the corresponding docking seat 232 and the threaded rod 1 231 to rotate synchronously through the docking plug 323, and the threaded rod 1 231 drives the corresponding transmission slide 233 along the guide rod 223 through the spiral transmission. The transmission slide 233 drives the corresponding transmission plug-in 342 and its corresponding connecting plate to move synchronously through the transmission sleeve 234, and the connecting plate drives the corresponding turning piece 341 to slide intermittently and regularly along the corresponding straight groove through the sliding shaft. The turning piece 341 then turns the spherical catalyst carrier inside the material tray 33 to both sides through the arc surface and inclined surface thereon to separate the material and expose it. The ball bearing can reduce the friction resistance of the turning piece 341 during the movement, and the protective cover 31 can prevent the influence of the humid and hot environment on the motor 321.

[0047] The above-mentioned operation method can realize automatic and continuous turning of the spherical catalyst carriers in the material tray 33 during the drying process, so that the spherical catalyst carriers originally wrapped inside can be continuously turned to the surface and directly contact the high-speed hot air flowing in the oven 1, thereby not only significantly increasing the proportion of spherical catalyst carriers that are directly dried and improving the overall drying uniformity of the spherical catalyst carriers, but also significantly shortening the overall drying time of the spherical catalyst carriers and improving the overall drying efficiency, thereby greatly reducing the overall heat energy consumption, improving energy utilization, and reducing the total energy consumption cost of production and processing.

[0048] The present invention also provides a drying method for spherical catalyst carriers after rounding, and the steps are as follows: Step 1, positioning and loading: first, the lifting support part 22 is driven by the lifting drive part 24, so that the operator places each material tray 33 in layers at a safe height on the lifting support part 22 in sequence, and the docking turning part 34 on the material tray 33 cooperates with the docking transmission part 23 on the lifting support part 22, and finally the movable frame 21 is guided and stably positioned in the oven 1 by the positioning mechanism 4.

[0049] Step 2, turning over and drying: when the movable frame 21 is stably positioned in the oven 1, the turning over driving part 32 is docked with the docking transmission part 23, and the docking turning over part 34 is driven by the transmission cooperation between the turning over driving part 32 and the docking transmission part 23 to continuously turn over the spherical catalyst carriers in the material tray 33, and at the same time, the spherical catalyst carriers are continuously dried with hot air through the oven 1 until the spherical catalyst carriers in all the material trays 33 are dried.
