Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, and more specifically, to a fixing mechanism for a molecular sieve for waste gas treatment. Background Technique

[0002] At present, a large amount of waste gas is generated during the production process of some chemical factories. Such gases contain a large number of harmful substances to the human body. Direct emission will affect people's physical health and cause environmental pollution. Therefore, waste gas needs to be treated before emission. A molecular sieve is an artificially synthesized hydrated silicoaluminate (zeolite) or natural zeolite with the function of screening molecules. It has many uniformly sized pores and neatly arranged cavities in its structure. Molecular sieves with different pore sizes separate molecules of different sizes and shapes. According to the molecular ratio of SiO2 and Al2O3, molecular sieves with different pore sizes are obtained. It has high adsorption capacity, strong selectivity, and high temperature resistance. Therefore, molecular sieves are widely used in waste gas treatment equipment.

[0003] Regarding the molecular sieve for waste gas treatment, there are many existing technologies, for example:

[0004] Chinese Patent Publication No. CN218221732U discloses a molecular sieve waste gas treatment device, which includes a bottom plate. A waste material box is fixedly installed on the bottom plate. The top of the waste material box is fixedly installed with a treatment box. A molecular sieve is fixedly installed in the treatment box. A fixing frame is fixedly installed on the left side of the molecular sieve in the treatment box. A plurality of ultraviolet lamps are fixedly installed on the fixing frame. A negative pressure fan is fixedly installed on the right side of the treatment box. An air inlet and an air outlet are arranged on the negative pressure fan. The air inlet on the negative pressure fan is communicated with the inside of the treatment box. A waste gas pipe is fixedly installed on the top of the treatment box, and a first solenoid valve is fixedly installed in the waste gas pipe. Through the mutual cooperation of the treatment box, the molecular sieve, the fixing frame, the negative pressure fan and the ultraviolet lamp, this molecular sieve waste gas treatment device can form multiple treatments of waste gas by using the ultraviolet lamp and the molecular sieve, and at the same time cooperate with the negative pressure fan to accelerate the passing speed of the waste gas in the treatment box, thereby further improving the working efficiency of waste gas treatment.

[0005] It can be seen from this that most molecular sieve fixing mechanisms mostly adopt a simple frame type to insert into the inside of the waste gas treatment device. Although this fixing method is simple, when treating a large amount of waste gas or high-concentration waste gas, the molecular sieve is prone to loosen or shift due to the impact of the air flow, resulting in a decrease in the adsorption efficiency, and even may cause safety accidents, which not only reduces the stability of the molecular sieve installation position, but also reduces the safety of the molecular sieve use, thereby reducing the performance of use.

[0006] In view of this, we propose a fixing mechanism for a molecular sieve for waste gas treatment. Summary of the Utility Model

[0027] Most of the molecular sieve fixing mechanisms adopt a simple frame type to insert into the waste gas treatment device. Although this fixing method is simple, when dealing with a large amount of waste gas or high-concentration waste gas, the molecular sieve is prone to loosen or shift due to air flow impact, resulting in a decrease in adsorption efficiency and even possible safety accidents, not only reducing the stability of the molecular sieve installation position, but also reducing the safety of the molecular sieve use, thus reducing the performance of use.

[0028] Please refer to Figures 1-4In the embodiment of the present utility model shown, the device includes an exhaust gas treatment machine 10 and a molecular sieve body 40. An installation component 20 is inserted and fitted through a plugging component 11 inside the opening above the exhaust gas treatment machine 10, and the molecular sieve body 40 is installed inside the installation component 20; on both sides below the plugging component 11, fixing components 30 are provided, and the fixing components 30 can strengthen the installation of the installation component 20 and the exhaust gas treatment machine 10.

[0029] First, the specific structure of the installation component 20 is disclosed. The installation component 20 at least includes an installation frame 21. On both sides of both ends of the opening of the installation frame 21, multi-stage cylinders 22 are provided, and a fixing frame 23 is provided on the piston rod of the multi-stage cylinder 22.

[0030] The improvement lies in: Connect the multi-stage cylinder 22 to the power supply to make it work. Through the work of pushing by the piston rod of the multi-stage cylinder 22, the fixing frame 23 is moved away from the installation frame 21. At this time, the molecular sieve body 40 can be replaced. After the molecular sieve body 40 is placed inside the installation frame 21, through the work of the piston rod of the multi-stage cylinder 22 resetting, the fixing frame 23 is moved closer to the installation frame 21, and the molecular sieve body 40 is clamped and installed. This not only improves the working efficiency of the installation and disassembly of the molecular sieve body 40, but also facilitates the replacement of the molecular sieve body 40, increases the working efficiency of the exhaust gas treatment machine 10, and also facilitates the later cleaning work of the molecular sieve body 40, thus improving the flexibility of the use of the fixing mechanism.

[0031] Secondly, the specific structure of the plugging component 11 is disclosed. The plugging component 11 at least includes a slot 111. The slot 111 is located inside the exhaust gas treatment machine 10, and an insertion frame 112 for plugging and fitting with the slot 111 is provided on the outer wall of the installation frame 21.

[0032] The improvement lies in: Align the insertion frame 112 with the opening above the slot 111, and press the installation component 20 into the exhaust gas treatment machine 10 to make the insertion frame 112 and the slot 111 plug and fit. This is not only simple to install and easy to disassemble, but also facilitates the replacement work of the molecular sieve body 40, improves the working efficiency of the installation, avoids waste of time, and thus improves the practicality of the fixing mechanism.

[0033] The specific structure of the fixing component 30 is disclosed again. The fixing component 30 includes at least two grooves 31, and the two grooves 31 are respectively located on both sides below the slot 111. A plurality of elastic members 32 are arranged inside the two grooves 31. A fixing rod 33 is arranged on the side of the plurality of elastic members 32 away from the slot 111, and the side of the fixing rod 33 close to the plug holder 112 is arc-shaped. An elastic sealing plate 34 is arranged in the cavity above the two grooves 31. The other end of the elastic sealing plate 34 is fixedly connected to the side of the fixing rod 33 close to the elastic member 32. Fixing grooves 35 for plugging and matching with the fixing rod 33 are respectively formed below both sides of the plug holder 112.

[0034] The improvement lies in that when the installation component 20 is inserted into the interior of the slot 111, when the plug holder 112 approaches the fixing rod 33, the arc surface of the fixing rod 33 is pressed by both sides of the bottom of the plug holder 112, so that the fixing rod 33 moves towards the interior of the groove 31. At the same time, the plurality of elastic members 32 and the elastic sealing plate 34 are deformed and contracted. Until the slot 111 and the plug holder 112 are plugged and matched, through the resilience of the plurality of elastic members 32, the fixing rod 33 is ejected from the interior of the groove 31 and is plugged and matched with the fixing groove 35, increasing the stability of the installation of the molecular sieve body 40. Similarly, when it is necessary to disassemble the installation component 20, the installation component 20 is pulled upward, and the fixing rod 33 is extruded by the inner wall of the fixing groove 35, so that the fixing rod 33 moves towards the interior of the groove 31. At the same time, the plurality of elastic members 32 and the elastic sealing plate 34 are deformed and contracted. Until the plug holder 112 is far away from the fixing rod 33, the fixing rod 33 will be reset through the plurality of elastic members 32. This not only has simple operation, increases the flexibility of the use of the fixing mechanism, but also improves the working efficiency of the installation and disassembly of the installation component 20, increases the convenience, and also improves the stability of the installation of the installation component 20, increasing the safety of the use of the molecular sieve body 40, thereby avoiding economic losses.

[0035] In order to increase the stability of the installation of the molecular sieve body 40 and the waste gas treatment machine 10 and reduce the looseness of the molecular sieve body 40 during use, therefore, sealing strips 24 are arranged on both sides of the outer wall of the mounting bracket 21.

[0036] The improvement lies in that the connection between the mounting bracket 21 and the waste gas treatment machine 10 is sealed through the sealing strip 24, which not only increases the stability of the connection between the installation component 20 and the waste gas treatment machine 10, reduces the frequency of looseness of the molecular sieve body 40 during use, but also increases the safety of the use of the molecular sieve body 40, thereby improving the practicability of the fixing mechanism.

[0037] In summary, the working principle of this solution is as follows: First, connect the multi-stage cylinder 22 to the power supply to make it work. Through the work of pushing by the piston rod of the multi-stage cylinder 22, move the fixing frame 23 away from the mounting frame 21. At this time, place the molecular sieve body 40 into the interior of the mounting frame 21, and through the work of the piston rod of the multi-stage cylinder 22 resetting, move the fixing frame 23 closer to the mounting frame 21 and clamp and install the molecular sieve body 40. After that, firmly hold the handle above the mounting frame 21, align the plug-in frame 112 with the opening above the slot 111, and press the mounting assembly 20 into the interior of the waste gas treatment machine 10, so that the plug-in frame 112 slides inside the slot 111. When the plug-in frame 112 approaches the fixed rod 33, press the arc surface of the fixed rod 33 through both sides at the bottom of the plug-in frame 112, so that the fixed rod 33 moves into the interior of the groove 31. At the same time, a plurality of elastic members 32 and the elastic sealing plate 34 are deformed and contracted until the slot 111 and the plug-in frame 112 are in plug-in fit. Then, through the resilience of the plurality of elastic members 32, the fixed rod 33 is ejected from the interior of the groove 31 and is in plug-in fit with the fixing groove 35, and the work of fixing the position of the molecular sieve body 40 can be completed.
