Description

Technical Field

[0001] This utility model relates to the field of gas purification technology, and in particular to an automated unloading horizontal adsorber. Background Technology

[0002] Horizontal adsorbers, as a commonly used adsorption device, are widely used in the field of air pollution control. After organic waste gas enters the adsorber, the organic matter is adsorbed by the adsorbent, and the discharged waste gas can directly meet emission standards. Saturated adsorbents need to be replaced regularly to ensure the purification effect on the organic waste gas. However, currently used adsorbers all require manual entry into the adsorber tank to unload the material using shovels or spades. Existing adsorbers still have some drawbacks:

[0003] 1. The existing unloading method has a high risk factor. The adsorbent adsorbs toxic and harmful gases, and workers are at risk of poisoning during operation.

[0004] 2. The interior of the tank is enclosed and relatively isolated from the outside world. The entrances and exits are narrow, which prevents workers from working inside for extended periods, thus affecting production efficiency.

[0005] 3. Poor ventilation inside the adsorber makes it difficult for toxic substances and other harmful factors to disperse. Moreover, during operation, harmful and toxic residues may gradually be released, increasing the amount of toxic or flammable materials and reducing oxygen, thus increasing the risk.

[0006] 4. The carbon canister is small and poorly ventilated, resulting in a lot of dust during operation and a harsh working environment. For large-size and large-capacity adsorbers, manual operation takes longer and the risk factor is greater.

[0007] 5. Rescue efforts are difficult if an accident occurs inside the tank during unloading.

[0008] Therefore, designing an adsorber with automatic unloading capability is of significant practical importance. Utility Model Content

[0009] In order to solve the above-mentioned technical problems in the prior art, this utility model provides an automated unloading horizontal adsorber.

[0010] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0011] This utility model provides an automated unloading horizontal adsorber, including an adsorber body, a first end cap, and a second end cap;

[0012] The upper part of the adsorber body is provided with a feed inlet and an air outlet, and the lower part of the adsorber body is provided with a discharge outlet and an air inlet. The feed inlet is close to the second end cap, and the discharge outlet is close to the first end cap.

[0013] The adsorbent body is provided with an adsorbent transfer mechanism inside, which extends along the axial direction of the adsorbent body.

[0014] The adsorbent transport mechanism includes a drive motor, a drive shaft, a drive sprocket, a first chain, a first driven sprocket, and a driven shaft connected in sequence. It also includes a second driven sprocket, a second chain, and a third driven sprocket connected in sequence. The first chain and the second chain are connected by a chain link. A transport mesh belt is provided on the chain link, and the transport mesh belt is used to lay the adsorbent.

[0015] The above technical solution has the following technical effects:

[0016] The automated unloading horizontal adsorber provided by this utility model can realize the automatic loading, transmission, gas adsorption and unloading of adsorbent materials in the adsorber without manual intervention. In particular, it eliminates the need for manual entry into the adsorber for unloading, avoiding the inhalation of toxic and harmful gases and other safety hazards, thus improving operational safety.

[0017] Based on the above technical solution, the present invention can be further improved as follows:

[0018] Furthermore, the second driven sprocket is sleeved on the end of the drive shaft away from the drive sprocket, and the third driven sprocket is sleeved on the end of the driven shaft away from the first driven sprocket.

[0019] Furthermore, the upper inner wall of the adsorber body is also provided with a retractable scraper, which can contact or move away from the conveyor belt.

[0020] The technical advantage of adopting the above-mentioned further technical solution is that: a retractable scraper is set up to scrape the adsorbent material laid on the conveyor belt to ensure the uniformity of the adsorbent material.

[0021] Furthermore, tensioning mechanisms are provided at both ends of the driven shaft.

[0022] Furthermore, the tensioning mechanism includes a tensioning bearing and a tensioning thread.

[0023] The technical advantage of adopting the above-mentioned further technical solution is that the tension can be adjusted by adjusting the tensioning thread according to the different tightness of the chain, so as to ensure the stability, safety and reliability of the transmission system.

[0024] Furthermore, both the first chain and the second chain are provided with upper chain guide rails at their upper parts, and both the first chain and the second chain are provided with lower chain guide rails at their lower parts.

[0025] The technical advantages of adopting the above-mentioned further technical solution are as follows: setting up upper and lower guide rails for the chain to support and guide the chain, reducing chain friction, reducing noise, and increasing the chain's service life.

[0026] Furthermore, an edge sealing plate is provided on the top of the transmission belt.

[0027] The technical effect of adopting the above-mentioned further technical solution is to prevent the adsorbent material from being lifted up and falling into the inner wall of the adsorber.

[0028] Furthermore, the adsorbent is laid on the conveyor belt with a thickness of 0.5-0.6 meters.

[0029] The technical effect of adopting the above-mentioned further technical solution is that this is the optimal thickness for the adsorbent material to be laid on the conveyor belt. If the thickness is too small, the adsorption effect will be poor. If the thickness is too large, the gas penetration resistance will increase and the adsorbent material will be wasted. Setting the laying thickness to 0.5-0.6 meters will result in the highest adsorption efficiency, which can meet the adsorption time requirements and reduce the gas penetration resistance.

[0030] Compared with the prior art, the present invention has the following technical effects:

[0031] The horizontal adsorber of this invention upgrades the loading of adsorbent material from a fixed support structure to a transmission type, and the loading and unloading parts are independently controlled, which does not affect the overall process operation of the equipment; it can realize automated loading and unloading, greatly reduce the time and effort of manual operation, reduce production costs, and improve the safety factor.

[0041] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Although the description of this utility model will be presented in conjunction with preferred embodiments, this does not mean that the features of this utility model are limited to this embodiment. On the contrary, the purpose of describing the utility model in conjunction with the embodiments is to cover other options or modifications that may be derived based on the claims of this utility model. To provide a deep understanding of this utility model, many specific details will be included in the following description. This utility model may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this utility model, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0042] See Figure 1-7 The automated unloading horizontal adsorber provided by this utility model includes a hollow adsorber body 1 with openings at both ends, and a first end cap 2 and a second end cap 3 disposed at both ends of the adsorber body 1; the upper part of the adsorber body 1 is provided with a feed inlet 8 and an air outlet 4, and the lower part of the adsorber body 1 is provided with a discharge outlet 12 and an air inlet 5; the feed inlet 8 is close to the second end cap 3, and the discharge outlet 12 is close to the first end cap 2.

[0043] The adsorbent body 1 is provided with an adsorbent transport mechanism inside. The adsorbent transport mechanism extends along the axial direction of the adsorbent body 1 so that the adsorbent material is evenly distributed inside the adsorbent body 1 and the adsorbent material is transported from one end of the inlet 8 to one end of the outlet 12.

[0044] The adsorbent transport mechanism includes a drive motor 6, a drive shaft 15, a drive sprocket, a first chain 17, a first driven sprocket, and a driven shaft 19 connected in sequence. It also includes a second driven sprocket, a second chain 29, and a third driven sprocket connected in sequence. The second driven sprocket is sleeved on the end of the drive shaft 15 away from the drive sprocket, and the third driven sprocket is sleeved on the end of the driven shaft 19 away from the first driven sprocket. The first chain 17 and the second chain 29 are connected by a chain link 18. A transport mesh belt 28 is provided on the chain link 18. The transport mesh belt 28 is used to lay the adsorbent. The transport mesh belt structure can ensure the permeability of gas phase molecules and achieve uniform distribution of airflow.

[0045] Specifically, the drive motor 6 is mounted on the outer wall of the adsorber body 1 via the fixing frame 13. When the drive motor 6 is started, it drives the drive shaft 15 connected to it to rotate. The drive shaft 15 drives the drive sprocket to rotate, and the drive sprocket drives the first chain 17 sleeved on it to rotate. The rotation of the first chain 17 further realizes the rotation of the first driven sprocket and the driven shaft 19. The drive shaft 15 further drives the rotation of the second driven sprocket and the second chain 29. The conveyor belt 28 also rotates synchronously. The adsorbent material enters the interior of the adsorber body 1 through the feed port 8 and is laid on the conveyor belt 28 located below the feed port 8. With the rotation of the conveyor belt 28, the adsorbent material is laid at different positions on the conveyor belt 28, that is, the maximum area of ​​adsorbent material is laid inside the adsorber body 1.

[0046] Optionally, the upper inner wall of the adsorber body 1 is also provided with a retractable scraper 27. The retractable scraper 27 can contact or move away from the conveyor belt 28 to spread the adsorbent material evenly. The thickness of the adsorbent on the conveyor belt 28 is 0.5-0.6 meters. By controlling the rotation speed of the drive motor 6 and the retractable scraper 27, the thickness of the adsorbent can be controlled, so as to meet the adsorption time requirements and reduce the gas penetration resistance.

[0047] Optionally, tensioning mechanisms are provided at both ends of the driven shaft 19. The tensioning mechanism includes a tensioning bearing 10 and a tensioning thread 11. The tension is adjusted by adjusting the tensioning thread 11 to ensure the stability, safety and reliability of the transmission system.

[0048] Optionally, both the first chain 17 and the second chain 29 are provided with an upper chain guide rail 21 at the top and a lower chain guide rail 22 at the bottom. During the chain transmission process, the upper chain guide rail 21 and the lower chain guide rail 22 support and guide the first chain 17 and the second chain 29 to reduce chain wear and improve service life.

[0049] Optionally, a sealing plate 23 is provided above the conveyor belt 28 to prevent the adsorbent laid on the conveyor belt 28 from being lifted up and falling into the bottom of the adsorbent body 1, while ensuring normal loading of adsorbent material and normal gas flow.

[0050] Optionally, the conveyor belt 28 is made of high-temperature resistant woven mesh, the size of its mesh openings is adapted to the particle size of the adsorbent material, the adsorbent material will not fall out of the mesh, and it can ensure that the gas molecules to be adsorbed can pass through freely without creating resistance to the gas molecules.

[0051] Optionally, the first chain 17 is provided with bottom sealing plates 24 at the ends near the first end cap 2 and the second end cap 3, respectively. One end of the bottom sealing plate 24 is connected to the lower guide rail 22 of the chain, and the other end is connected to the inner bottom wall of the adsorber body 1. This prevents the fallen adsorbent material from scattering into other parts inside the adsorber body 1. At the same time, it guides the gas entering through the air inlet 5, preventing gas molecules from moving upwards from the ends of the first end cap 2 and the second end cap without being adsorbed and being discharged through the air outlet 4.

[0052] Optionally, the bottom outer wall of the adsorber body 1 is also provided with a support foot 9 to support the adsorber body 1; the end of the first end cap 2 of the adsorber body 1 is also provided with a manhole 7 to facilitate the entry of personnel into the adsorber body 1 for inspection and maintenance.

[0053] Optionally, a fixed bearing 14 is provided at one end of the drive shaft 15 near the second driven sprocket to reduce the friction during the rotation of the drive shaft 15 and ensure rotational accuracy; a first cover that cooperates with the outer wall of the adsorber body 1 is also provided on the outside of the fixed bearing 14, and a second cover that cooperates with the outer wall of the adsorber body 1 is provided on the outside of the tensioning mechanism to achieve sealing.

[0054] The specific process steps for gas adsorption using this automated unloading horizontal adsorber are as follows:

[0055] (1) Adsorbent loading: Start the drive motor 6. The drive motor 6 drives the first chain 17, the second chain 29, the chain connecting rod 18 and the conveyor belt 28 to move uniformly. The adsorbent is added into the interior of the adsorbent body 1 through the feed port 8 and falls to the corresponding position of the conveyor belt 28 below the feed port 8. As the conveyor belt 28 moves, the adsorbent gradually covers the entire surface of the conveyor belt 28. At the same time, the retractable scraper 27 spreads the adsorbent material on the surface of the conveyor belt 28 evenly, so that the thickness of the adsorbent on the conveyor belt 28 is 0.5-0.6 meters, ensuring that the airflow penetrates the adsorbent evenly and improving the adsorption efficiency. At this time, the drive motor 6 is turned off.

[0056] (2) Gas adsorption purification: Open the air inlet 5, and the gas to be purified enters the adsorber body 1 through the air inlet 5. The gas moves upward inside the adsorber body 1, and after being adsorbed and purified by the adsorbent, it continues to move upward and is discharged through the air outlet 4.

[0057] (3) Adsorbent unloading: When it is necessary to replace the adsorbent, open the outlet 12 and start the drive motor 6. The adsorbent is driven to the outlet 12 by the conveyor belt 28. Under its own weight, the adsorbent falls through the outlet 12 to the external collection device. With the movement of the conveyor belt 28, all the adsorbent is finally unloaded.

[0058] (4) Repeat the above steps to achieve continuous automatic loading, adsorption and unloading.

[0059] The automated unloading horizontal adsorber provided by this utility model improves the traditional fixed support structure of the adsorbent to a transmission type. The structure is simple and reliable. It can realize the automatic loading, spreading and unloading of adsorbent material without the need for manual entry into the adsorbent body 1, which improves work efficiency and is safe and hygienic. It avoids the hazards of working in confined spaces and prevents the inhalation of toxic and harmful gases and adsorbent dust during manual operation, thus ensuring the health of the workers. Moreover, the loading and unloading system is an independent control system, which does not affect the process operation of the entire equipment. At the same time, the modular design facilitates maintenance and replacement of parts.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
