Description

Technical Field

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

[0002] In a chemical reaction, a substance that can change the rate of a chemical reaction (increase or decrease) without changing the chemical equilibrium, and whose own mass and chemical properties remain unchanged before and after the chemical reaction, is called a catalyst (solid catalysts are also called catalysts).

[0003] Existing catalyst pelletizing devices involve adding catalyst and binder into a pelletizing tank, where they combine and then fall into a pelletizing column via droppers. During this process, the catalyst and binder need to be added in a specific ratio. This type of device cannot control the amount of catalyst and binder added, easily leading to an imbalance in the catalyst-binder ratio, which in turn affects the catalytic efficiency of the resulting spherical catalyst in use. Therefore, we provide a catalyst pelletizing device to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a catalyst pelletizing device. The addition amount of catalyst and binder is controlled by a mixing component, and then the two are stirred evenly by a stirring group. The stirred binder is dropped into the pelletizing column through a dropper. Finally, the mixture is shrunk into a spherical shape by an oil-ammonia forming method, and finally a spherical catalyst is obtained. This solves the problem of low catalytic efficiency of the generated spherical catalyst due to the imbalance of the ratio of catalyst and binder in the existing method.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a catalyst pelletizing device, including a support assembly, a mixing assembly, and a stirring assembly. The support assembly includes a support plate, which is mounted on an external frame. A pelletizing column is mounted on the top of the support plate. The mixing assembly is mounted above the support plate and includes a pelletizing box, which is mounted above the support plate. Two guide rods are fixedly installed inside the pelletizing box. A guide hole corresponding to the guide rod is opened at the bottom of the pelletizing box. Several drippers are fixedly installed at the bottom of the pelletizing box, and the drippers are positioned above the pelletizing column. The stirring assembly is installed inside the pelletizing box and includes a stirring rod, which is rotatably connected to the pelletizing box.

[0006] The present invention is further configured such that two L-shaped limiting plates are fixedly provided on the top of the support plate, a positioning plate is fixedly provided between the two L-shaped limiting plates, a first motor and a second motor are installed on the top of the positioning plate, two support rods are fixedly provided at the bottom of the positioning plate, the bottom of the support rods is fixedly connected to the top of the dripping ball box, a guide rod is fixedly provided between the positioning plate and the dripping ball box, and a positioning threaded rod is rotatably provided between the positioning plate and the dripping ball box.

[0007] The present invention is further configured such that the output end of the first motor is fixedly connected to one end of the positioning threaded rod, the mixing component further includes a movable disk, the movable disk and the guide rod are slidably engaged, the movable disk and the positioning threaded rod are threadedly engaged, a first storage cylinder and a second storage cylinder are fixedly disposed at the bottom of the movable disk, the first storage cylinder and the second storage cylinder are connected by a positioning frame, and an elastic reset member is fixedly disposed inside the first storage cylinder and the second storage cylinder.

[0008] The present invention is further configured such that a sealing plate is fixedly provided at the bottom of the elastic reset member, and a discharge pipe is fixedly provided at the bottom of the first and second storage cylinders. The sealing plate is adapted to the corresponding discharge pipe, and the discharge pipe corresponds one-to-one with the guide rod. Two feed pipes are provided at the top of the moving disk, and the first and second storage cylinders are both connected to the inside of the corresponding feed pipes. A connecting rod is fixedly provided at the top of the stirring rod, penetrating the moving disk. The connecting rod is rotatably connected to the positioning plate, and the output end of the second motor is fixedly connected to one end of the connecting rod.

[0009] This utility model has the following beneficial effects: 1. This utility model drives the first motor to rotate the positioning threaded rod, the positioning plate moves and drives the first and second storage cylinders to move, the discharge pipe moves downward and drives the sealing plate to move. During this process, the guide rod is inserted into the discharge pipe and pushes the corresponding sealing plate in the opposite direction. When the sealing plate is pushed above the discharge pipe, the catalyst in the first storage cylinder and the binder in the second storage cylinder enter the dropper box at the same time along the discharge pipe. The catalyst mixture after the catalyst and binder are mixed falls into the balling column through the dropper. The catalyst mixture falling into the balling column is shrunk into a spherical shape by the oil-ammonia forming method, and finally a spherical catalyst is obtained. This process controls the addition of catalyst and binder by the sealing plate, so that the ratio of catalyst and binder added to the dropper box is appropriate, which further improves the catalytic efficiency of the generated spherical catalyst.

[0010] 2. This utility model drives a second motor to rotate a connecting rod, and the stirring rod rotates synchronously to stir the catalyst and binder. This process can fully stir the catalyst and binder, so that the proportion of powdered catalyst and binder in the mixture is evenly distributed, which indirectly improves the catalytic efficiency of the spherical catalyst.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] For a specific implementation example, please refer to Implementation Example 1. Figure 1-9 This utility model is a catalyst pelletizing device, including a support assembly 1, which includes a support plate 101, a mixing assembly 2, and a stirring assembly 3. The support plate 101 is mounted on an external frame, and a pelletizing column 4 is mounted on the top of the support plate 101. The mixing assembly 2 is mounted above the support plate 101 and includes a pelletizing box 201, which is mounted above the support plate 101. Two guide rods 202 are fixedly installed inside the pelletizing box 201, and a guide hole 203 corresponding to the guide rods 202 is opened at the bottom of the pelletizing box 201. Several drippers 212 are fixedly installed at the bottom of the pelletizing box 201, and the drippers 212 are located above the pelletizing column 4. The stirring assembly 3 is installed inside the pelletizing box 201 and includes a stirring rod 301, which is rotatably connected to the pelletizing box 201.

[0025] Specifically, two L-shaped limiting plates 102 are fixedly installed on the top of the support plate 101, and a positioning plate 103 is fixedly installed between the two L-shaped limiting plates 102. A first motor 104 and a second motor 105 are installed on the top of the positioning plate 103. Two support rods 106 are fixedly installed at the bottom of the positioning plate 103, and the bottom of the support rods 106 is fixedly connected to the top of the dripping ball box 201. A guide rod 107 is fixedly installed between the positioning plate 103 and the dripping ball box 201. A positioning threaded rod 108 is rotatably installed between the positioning plate 103 and the dripping ball box 201. The output end of the first motor 104 is fixedly connected to one end of the positioning threaded rod 108. The mixing component 2 also includes a moving disk 204. The moving disk 204 is slidably engaged with the guide rod 107 and threadedly engaged with the positioning threaded rod 108. A first storage cylinder 205 and a second storage cylinder 206 are fixedly installed at the bottom of the moving disk 204. The first storage cylinder 205 and the second storage cylinder 206 are connected by a positioning frame 207.

[0026] In the operation of this embodiment: a catalyst is added to the first storage cylinder 205, and a binder is added to the second storage cylinder 206. Then, the catalyst and the binder are added to the dropper box 201 at the same time. During this process, the catalyst and the binder are stirred by the stirring component 3 so that the two are mixed and then dropped into the spherical column 4 through the dropper 212. The catalyst mixture falling into the spherical column 4 is shrunk into a spherical shape by the oil-ammonia forming method, and finally spherical catalyst is obtained.

[0027] In the second specific embodiment, based on the first specific embodiment, an elastic reset member 208 is fixedly installed inside the first storage cylinder 205 and the second storage cylinder 206. A sealing plate 209 is fixedly installed at the bottom of the elastic reset member 208 (the periphery of the elastic reset member 208 is provided with an anti-sticking material to prevent the elastic reset member 208 from being stuck by the adhesive, and at the same time, the elastic force of the elastic reset member 208 is large enough so that the elastic reset member 208 can bounce inside the adhesive). A discharge pipe 210 is fixedly installed at the bottom of the first storage cylinder 205 and the second storage cylinder 206. The sealing plate 209 is adapted to the corresponding discharge pipe, and the discharge pipe 210 corresponds one-to-one with the guide rod 202.

[0028] Specifically, the top of the moving disk 204 is provided with two feed pipes 211 (the inner diameter ratio of the discharge pipes 210 of the first storage cylinder 205 and the second storage cylinder 206 is designed according to the ratio of catalyst and binder so that the ratio of catalyst and binder is adapted within a certain period of time). The first storage cylinder 205 and the second storage cylinder 206 are both connected to the inside of the corresponding feed pipes 211. The top of the stirring rod 301 is fixedly provided with a connecting rod 302 that passes through the moving disk 204. The connecting rod 302 is rotatably connected to the positioning plate 103. The output end of the second motor 105 is fixedly connected to one end of the connecting rod 302.

[0029] The operation process of this embodiment is as follows: In the initial state, the sealing disc 209 is located inside the corresponding discharge pipe 210, and the bottom of the discharge pipe 210 is located inside the corresponding through hole 203. The feed pipe 211 on the first storage cylinder 205 is opened to add catalyst to the first storage cylinder 205. The feed pipe 211 on the second storage cylinder 206 is opened to add adhesive to the second storage cylinder 206. Then, the first motor 104 is driven to drive the positioning threaded rod 108 to rotate, and the positioning plate 103 moves downward to drive the first... The first storage cylinder 205 and the second storage cylinder 206 move downwards, and the discharge pipe 210 moves downwards, causing the sealing disc 209 to move downwards. During this process, the guide rod 202 is inserted into the discharge pipe 210 and pushes the corresponding sealing disc 209 upwards. The elastic reset member 208 is compressed. When the sealing disc 209 is pushed above the discharge pipe 210, the catalyst in the first storage cylinder 205 and the binder in the second storage cylinder 206 simultaneously enter the drip ball box 201 along the discharge pipe 210 (here). During the process, the ratio of catalyst to binder is controlled by the ratio of the discharge pipe 210. In this process, the second motor 105 drives the connecting rod 302 to rotate, and the stirring rod 301 rotates synchronously to stir the catalyst and binder. The catalyst mixture after the catalyst and binder are mixed falls into the spherical column 4 through the dropper 212. The catalyst mixture falling into the spherical column 4 is shrunk into a spherical shape by the oil-ammonia forming method, and finally a spherical catalyst is obtained. In this process, the first motor 104 drives the positioning threaded rod 108 to rotate in the opposite direction, the positioning plate 103 moves upward, and the first storage cylinder 205 and the second storage cylinder 206 move upward. The discharge pipe 210 moves upward, and the sealing plate 209 moves upward. In this process, the guide rod 202 moves out of the discharge pipe 210. Under the action of the elastic reset member 208, the sealing plate 209 moves downward back to the initial position. Then, the above operation is continued to complete the preparation of the spherical catalyst.
