Description

Technical Field

[0001] This utility model relates to the field of methanol-to-hydrogen technology, specifically to a quick-installation mechanism for easy catalyst replacement in a methanol-to-hydrogen converter. Background Technology

[0002] Methanol-to-hydrogen (MHT) is a technology that converts methanol into hydrogen through a chemical reaction, and it is one of the important hydrogen production routes in the chemical industry. Its core principle is to use methanol to undergo reforming, cracking, or partial oxidation reactions with water or other reactants under the conditions of catalyst and heating to produce a hydrogen-rich mixed gas. High-purity hydrogen is then obtained through separation and purification. However, the catalytic effect of the catalyst will decrease after long-term use, and if it is not replaced in time, it will affect the hydrogen production efficiency.

[0003] Currently, most catalyst carrier plates on the market are fixed with bolts. Each time the catalyst carrier plate is disassembled or installed, it takes a lot of time for the staff. The operation is cumbersome and inconvenient. At the same time, in most hydrogen production processes, the staff cannot directly observe the state of the catalyst, so when the catalyst activity decreases, it cannot be replaced in time, which affects the efficiency of methanol to hydrogen production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a quick-installation mechanism for catalyst replacement in a methanol-to-hydrogen converter, which has the advantages of easy replacement and easy observation, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a quick-installation mechanism for easy catalyst replacement in a methanol-to-hydrogen converter, comprising a device housing, an inlet pipe fixedly installed on the upper end face of the device housing, an outlet pipe fixedly installed on the lower end face of the device housing, a sealing door fixedly installed on the front end face of the device housing, multiple fixing bolts threadedly connecting the sealing door and the device housing, a cleaning mechanism fixedly installed inside the sealing door, a quartz glass plate fixedly installed inside the cleaning mechanism, and multiple snap-fit ​​mechanisms fixedly installed on the inner walls of both sides of the device housing, with catalyst storage mechanisms snapped between each pair of the multiple snap-fit ​​mechanisms.

[0006] As a preferred technical solution of this utility model, the cleaning mechanism includes two limiting rods, each of the two limiting rods having a first groove on its front end face, each of the two first grooves having a first magnetic block slidably installed inside, and each of the two first magnetic blocks having a first connecting rod fixedly installed on its front end face.

[0007] As a preferred technical solution of this utility model, a second sliding groove is provided on the rear end face of both limiting rods, a second magnetic block is slidably installed inside the two second sliding grooves, a second connecting rod is fixedly installed on the rear end face of the two second magnetic blocks, and a cleaning block is fixedly installed on the front end face of the second connecting rod.

[0008] As a preferred embodiment of this utility model, the locking mechanism includes a locking rod, a return spring is fixedly installed inside the locking rod, and a connecting block is fixedly installed on the upper end face of the return spring.

[0009] As a preferred embodiment of this utility model, a top block is fixedly installed on the upper end face of the connecting block, and a pressing handle is fixedly installed on one side of the connecting block.

[0010] As a preferred embodiment of the present invention, the catalyst storage mechanism includes a housing, a catalyst carrier plate is fixedly installed inside the housing, and two grooves are formed on the lower end face of the housing.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The quick-release mechanism for easy catalyst replacement in this methanol-to-hydrogen converter uses a snap-fit ​​mechanism to fix the catalyst storage mechanism. When the catalyst activity decreases and needs to be replaced, the handle can be pressed to compress the reset spring, causing the top block to disengage from the groove. The catalyst storage mechanism can then be quickly disassembled and replaced by sliding it. This is more convenient and faster than traditional bolt fixing.

[0012] 2. The quick-installation mechanism for catalyst replacement in this methanol-to-hydrogen converter utilizes a quartz glass plate installed inside a sealed compartment. During hydrogen production, operators can observe the catalyst's condition through the quartz glass plate, allowing for timely catalyst replacement when its activity decreases, thus ensuring hydrogen production efficiency. When moisture adheres to the inner wall of the quartz glass plate, affecting observation, the first connecting rod can be slid up and down. The adsorption effect of the first and second magnetic blocks moves the cleaning block up and down to remove moisture, ensuring that operators can observe the catalyst's condition in real time.

[0015] 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.

[0016] Please see Figures 1-6 A quick-installation mechanism for easy catalyst replacement in a methanol-to-hydrogen converter includes a device housing 2, an inlet pipe 1 fixedly installed on the upper end face of the device housing 2, an outlet pipe 7 fixedly installed on the lower end face of the device housing 2, a sealing door 5 fixedly installed on the front end face of the device housing 2, a plurality of fixing bolts 6 threadedly connected between the sealing door 5 and the device housing 2, a cleaning mechanism 3 fixedly installed inside the sealing door 5, a quartz glass plate 4 fixedly installed inside the cleaning mechanism 3, a plurality of snap-fit ​​mechanisms 8 fixedly installed on the inner walls of both sides of the device housing 2, and a catalyst storage mechanism 9 snap-fitted between each pair of snap-fit ​​mechanisms 8; In the above structure, the methanol and water mixture enters the device housing 2 through the inlet pipe 1, and reacts to produce hydrogen under the action of the catalyst. The generated mixture is then discharged from the outlet pipe 7. The locking mechanism 8 is used to lock and fix the catalyst storage mechanism 9. The sealing door 5 is installed and fixed to the front end of the device housing 2 by the fixing bolts 6. The operator can observe the catalyst status through the quartz glass plate 4, which allows for timely replacement when the catalyst activity decreases, thus ensuring hydrogen production efficiency. When water vapor adheres inside the quartz glass plate 4 and makes it difficult to observe the catalyst status, the water vapor can be removed by the cleaning mechanism 3.

[0017] In a preferred embodiment, the cleaning mechanism 3 includes two limiting rods 301. Each of the two limiting rods 301 has a first sliding groove 302 on its front end face. Each of the two first sliding grooves 302 has a first magnetic block 303 slidably installed inside. Each of the two first magnetic blocks 303 has a first connecting rod 304 fixedly installed on its front end face. Each of the two limiting rods 301 has a second sliding groove 308 on its rear end face. Each of the two second sliding grooves 308 has a second magnetic block 307 slidably installed inside. Each of the two second magnetic blocks 307 has a second connecting rod 306 fixedly installed on its rear end face. Each of the two connecting rods 306 has a cleaning block 305 fixedly installed on its front end face. In the above structure, the mutual attraction between the first magnetic block 303 and the second magnetic block 307 allows the cleaning block 305 to move along the other side when the first connecting rod 304 slides up and down, thereby cleaning the water vapor on the other side of the quartz glass plate 4 and preventing the water vapor from affecting the observation of the staff.

[0018] In a preferred embodiment, the latching mechanism 8 includes a latching rod 801, a return spring 802 fixedly installed inside the latching rod 801, a connecting block 803 fixedly installed on the upper end face of the return spring 802, a top block 804 fixedly installed on the upper end face of the connecting block 803, and a pressing handle 805 fixedly installed on one side of the connecting block 803. The catalyst storage mechanism 9 includes a mechanism housing 901, a catalyst carrier plate 903 fixedly installed inside the mechanism housing 901, and two grooves 902 formed on the lower end face of the mechanism housing 901. In the above structure, under the action of the return spring 802, the top block 804 is engaged into the groove 902, thereby fixing the catalyst storage mechanism 9. When the catalyst needs to be replaced, simply press the handle 805 to compress the return spring 802 and disengage the top block 804 from the groove 902, so that the catalyst can be replaced through the sliding mechanism housing 901.

[0019] The working principle is as follows: the catalyst storage mechanism 9 is fixed by the snap-fit ​​mechanism 8. When the catalyst needs to be replaced, simply press the handle 805 to compress the reset spring 802 and disengage the top block 804 from the groove 902. Then, the catalyst can be replaced in time by simply sliding the catalyst storage mechanism 9. During the methanol-to-hydrogen process, the staff can observe the catalyst status through the quartz glass plate 4, so that the catalyst can be replaced in time when it is deactivated. When the observation effect is affected by water vapor inside the quartz glass plate 4, the first connecting rod 304 can be slid up and down. Under the mutual attraction of the first magnetic block 303 and the second magnetic block 307, the cleaning block 305 can be moved up and down to remove water vapor and ensure the observation effect of the quartz glass plate 4.
