Description

Technical Field

[0001] This utility model relates to the field of biogas treatment technology, specifically to a biogas dehydration device. Background Technology

[0002] During biogas production, due to the diversity of raw materials and varying fermentation conditions, the resulting biogas contains a significant amount of moisture. If this moisture is not dehydrated, it will reduce the calorific value of the biogas, affect its combustion efficiency, and may even corrode gas pipelines and equipment. Therefore, biogas dehydration is a crucial step in improving biogas quality and utilization efficiency.

[0003] One common method in biogas dehydration is to use absorbent materials such as sponges to absorb moisture from the biogas. After absorbing water, the sponge needs to be dehydrated. Currently, some biogas dehydration devices use internal compression to dehydrate the sponge. However, this method suffers from poor dehydration and insufficient compression, resulting in the inability to effectively remove moisture from the sponge, thus affecting the biogas dehydration effect.

[0004] For example, Chinese patent CN220149574U discloses a novel biogas dehydration device. By setting up a motor, screw, threaded sleeve, slide groove, slider, connecting rod and extrusion plate, after the sponge absorbs the moisture in the biogas, the operator can start the motor through the controller, so that the motor drives the screw to rotate, the screw drives the threaded sleeve to move, and then the threaded sleeve drives the extrusion plate to move through the connecting rod, so as to squeeze the moisture out of the sponge.

[0005] In this patent, the device for supporting the sponge is a support net. The support net works with the extrusion plate to dehydrate the sponge. However, the support net has many holes and a small support surface, which makes it unable to effectively squeeze the sponge at the hole positions, resulting in insufficient dehydration of the sponge. Utility Model Content

[0006] In view of this, the present invention provides a biogas dehydration device, which can fill the gaps in the slots, reduce the gaps in the surface supporting the sponge, and compress the sponge more fully.

[0007] To solve the above-mentioned technical problems, this utility model provides a biogas dehydration device, including a dehydration tank and a compression assembly. A support is fixedly connected to the middle of the dehydration tank, and multiple arrayed outlets are opened in the middle of the support. The compression assembly is set on the top of the support, and the compression assembly includes multiple top blocks fixedly connected to the upper side of the support. A guide assembly is set in the middle of the support, and a tray is fixedly connected to the top of the guide assembly. A sponge is placed on the top of the tray, and multiple slots are opened in the middle of the tray. The slots correspond one-to-one with the upper and lower positions of the top blocks, and the shape of the slots is consistent with the shape of the adjacent top blocks. A telescopic column is fixedly connected to the upper inside of the dehydration tank, and a compression plate is fixedly connected to the telescopic end of the telescopic column. The top of the top block can move to a height higher than the top of the tray to fill the gaps in the slots, reduce the gaps in the surface supporting the sponge, and can more fully compress the sponge.

[0008] The extrusion assembly includes multiple protrusions fixedly connected to the bottom of the extrusion plate; this enhances the local pressure on the sponge and improves the dehydration efficiency.

[0009] The extrusion plate has multiple arrayed through holes in the middle, with the through holes and protrusions interspersed; this allows biogas gas to directly contact the sponge through the through holes.

[0010] The top of the extrusion plate is fixedly connected with multiple reinforcing ribs, which increases the strength and stability of the extrusion plate and ensures uniform pressure on the sponge during the extrusion process.

[0011] It includes multiple guide columns that are slidably connected to the middle of the support, with the same support plate fixedly connected to the top of each guide column, and a spring sleeved in the middle of each guide column; thus ensuring the stability of the support plate during the extrusion process.

[0012] The guide assembly also includes a limiting plate. Two adjacent guide posts form a group, and the bottom of each group of guide posts is fixedly connected to the same limiting plate; that is, the existence of the limiting plate ensures the stability of the movement of the guide posts.

[0013] The dehydration tank has a vent at the top and a drain valve fixedly connected to the bottom, which facilitates the exchange of substances between the inside of the dehydration tank and the outside.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. Because the top block is relatively high, its top can be moved to a height higher than the top of the tray, filling the gaps in the slots, reducing the gaps in the surface supporting the sponge, and allowing the sponge to be squeezed more fully.

[0016] 2. Because sponges thicken after absorbing water, uneven height can easily occur during compression. Reinforcing ribs increase the strength and stability of the extrusion plate, ensuring that pressure is applied evenly to the sponge during extrusion. This helps prevent deformation or bending of the extrusion plate during extrusion, especially when processing thicker sponges or sponges with high moisture content.

[0017] 3. The array distribution of guide pillars ensures the stability of the pallet during vertical movement. The presence of guide pillars also prevents lateral movement of the pallet during the extrusion process, ensuring the accuracy and repeatability of the extrusion process. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0029] like Figure 1-6 As shown: This embodiment provides a biogas dehydration device, including a dehydration tank 100 and an extrusion assembly 200. A support 101 is fixedly connected to the middle of the dehydration tank 100. A plurality of arrayed outlets 102 are opened in the middle of the support 101. An extrusion assembly 200 is provided on the top of the support 101. The extrusion assembly 200 includes a plurality of top blocks 201 fixedly connected to the upper side of the support 101. A guide assembly 300 is provided in the middle of the support 101. A tray 202 is fixedly connected to the top of the guide assembly 300. A sponge is placed on the top of the tray 202. A plurality of slots 203 are opened in the middle of the tray 202. The slots 203 correspond one-to-one with the upper and lower positions of the top blocks 201. The thickness of the top block 201 is greater than the thickness of the slot 203. The shape of the slot 203 is consistent with the shape of the adjacent top blocks 201. A telescopic column 204 is fixedly connected to the upper inside of the dehydration tank 100. An extrusion plate 205 is fixedly connected to the telescopic end of the telescopic column 204.

[0030] When the sponge is compressed, the telescopic column 204 is extended and retracted, causing the compression plate 205 to move downwards, bringing it into contact with the sponge and applying pressure. The sponge is then compressed, and some of the water in the sponge flows out through the slots 203. As the telescopic column 204 continues to move downwards, the sponge and the support plate 202 move synchronously along the guide assembly 300, bringing the support plate 202 closer to the bracket 101. With the movement of the support plate 202, the top block 201 also inserts into the adjacent slots 203, and the sponge is positioned at the slot 203. The sponge is squeezed at the slot 203. Since the top block 201 is relatively high, its top can move to a height higher than the top of the support plate 202, filling the gap in the slot 203 and squeezing the sponge more fully. During this process, the sponge is fully supported by the support plate 202 and the top block 201. As the squeezing continues, the water in the sponge is discharged from the dehydration tank 100 through the drain 102. Since the drain 102 is distributed in an array, this ensures that the water is discharged evenly and avoids incomplete dehydration due to poor drainage.

[0031] 206 bumps Figure 4 , 5 As shown,

[0032] The extrusion assembly 200 also includes a plurality of protrusions 206 fixedly connected to the bottom of the extrusion plate 205. The lower surfaces of the protrusions 206 are all arc surfaces, and the protrusions 206 are distributed in an array.

[0033] When the extrusion plate 205 moves down and comes into contact with the sponge, the protrusion 206 also comes into contact with the sponge. Its arc shape can form a good fit with the sponge surface, thereby applying local pressure to the sponge during the extrusion process, providing additional pressure points, and thus enhancing the dehydration effect.

[0034] Through hole 103 Figure 2 , 3 As shown in Figures 4 and 5,

[0035] The middle part of the extrusion plate 205 has multiple arrayed through holes 103, and the through holes 103 and the protrusions 206 are distributed alternately.

[0036] The biogas gas inside the dehydration tank 100 can directly contact the sponge through the through hole 103, allowing the sponge to work normally.

[0037] Reinforcing ribs 104 Figure 2 , 3 As shown,

[0038] The top of the extrusion plate 205 is fixedly connected with multiple staggered reinforcing ribs 104;

[0039] Since sponges thicken after absorbing water, and compression can easily cause uneven height, reinforcing ribs 104 increase the strength and stability of the extrusion plate 205, ensuring that the extrusion plate 205 applies pressure evenly to the sponge during compression. This helps prevent the extrusion plate 205 from deforming or bending during compression, especially when processing thicker sponges or sponges with high moisture content.

[0040] Guide column 301 Figure 2 , 3 As shown in Figures 4 and 5,

[0041] It includes multiple arrayed guide columns 301 that are slidably connected to the middle of the bracket 101. The top of the guide column 301 is fixedly connected to the same support plate 202, and the middle part of the guide column 301 is fitted with a spring 302.

[0042] As the extrusion plate 205 moves downward to compress the sponge, the support plate 202 moves downward above the guide post 301. During this time, the spring 302 is compressed, storing energy. As the extrusion proceeds, the elasticity of the spring 302 helps the support plate 202 maintain contact with the extrusion plate 205, ensuring the sponge receives uniform pressure throughout the extrusion process. After extrusion is complete, the extrusion plate 205 and support plate 202 rise, and the spring 302 returns to its original position, releasing the stored energy and helping the support plate 202 quickly return to its initial position. This allows the support plate 202 to be quickly ready for the next dehydration operation, improving the efficiency of the dehydration device. Furthermore, the array distribution of the guide posts 301 ensures the stability of the support plate 202 during vertical movement. The presence of the guide posts 301 also prevents lateral movement of the support plate 202 during the extrusion process, ensuring the accuracy and repeatability of the extrusion process.

[0043] Limit plate 303 Figure 2 , 4 As shown,

[0044] The guide assembly 300 also includes a limiting plate 303. Two adjacent guide posts 301 form a group, and the bottom of each group of guide posts 301 is fixedly connected to the same limiting plate 303.

[0045] After extrusion is completed, the extrusion plate 205 and the support plate 202 rise. The limiting plate 303 restricts the upward movement distance of the support plate 202, ensuring that the movement range of the support plate 202 is within a safe and effective range. Since each limiting plate 303 is connected to multiple guide posts 301, the synchronicity of the movement of the guide posts 301 can be improved.

[0046] Vent 105 Figure 1 , 2 As shown,

[0047] The top of the dehydration tank 100 is provided with a vent 105, and the bottom of the dehydration tank 100 is fixedly connected to a drain valve 106.

[0048] The dehydration tank 100 is connected to an external device via vent 105 for gas exchange between the inside and outside. The drain valve 106 at the bottom of the dehydration tank 100 is used to drain the squeezed-out water. During the squeezing process, the water in the sponge is squeezed out and discharged through the leak 102 on the support 101, and finally discharged from the dehydration tank 100 through the drain valve 106.

[0049] Working principle:

[0050] By controlling the telescopic column, the extrusion plate moves downward, contacting the sponge and applying pressure. Moisture in the sponge flows out through the slot. As the telescopic column continues to move downward, the tray and sponge move along the guide assembly. The top block inserts into the slot, further squeezing the sponge and causing water to drain out of the dehydration tank through the outlet. A protrusion below the extrusion plate contacts the sponge, providing localized pressurization. A through-hole in the center of the extrusion plate allows biogas to directly contact the sponge, enhancing the dehydration effect. Reinforcing ribs increase the strength of the extrusion plate and ensure uniform extrusion. Springs on the guide columns are compressed during extrusion, storing energy. After extrusion, the springs return to their original shape, helping the tray quickly return to its initial position, ready for the next dehydration operation. A limiting plate restricts the upward movement distance of the tray, ensuring safe and effective movement. The array distribution of the guide columns ensures the stability of the tray's movement and prevents lateral movement.

[0051] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0052] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
