Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to an activated carbon waste gas treatment device applied to the medical waste feeding step. Background Technology

[0002] Medical waste refers to waste generated by medical and health institutions during medical treatment, prevention, health care and other related activities that has direct or indirect infectiousness, toxicity and other hazards. Medical waste may contain a large number of pathogenic microorganisms and harmful chemicals, which may cause the spread of diseases or related public health problems. Therefore, medical waste must be treated to render it harmless.

[0003] In existing technologies, medical waste is generally transported to a medical waste disposal unit, weighed and unloaded, then loaded into a transport box and pushed into a microwave steam treatment device. The waste is then fed into the inlet by a feeding device, and then crushed by a crushing device before being sterilized and disinfected by microwave and high temperature. After sterilization and disinfection, the waste exits from the discharge port, is automatically bagged, and then transported to the outsourced solid waste incineration unit for incineration. However, before medical waste is transferred from the temporary storage area to the loading point, it generates a large amount of waste gas due to the presence of pathogenic microorganisms and harmful chemicals. If the waste gas is not treated before crushing, it will emit a strong odor during the crushing process, affecting not only the workshop environment but also potentially harming the health of workers. Currently, a layered drawer-type activated carbon device can be used to treat the waste gas from medical waste. A negative pressure fan transfers the medical waste from the temporary storage area to the layered drawer-type activated carbon device, where the activated carbon adsorbs and treats the waste gas. However, after use, the activated carbon in this device needs to be replaced. The activated carbon used is usually granular, and a large amount of granular activated carbon is poured onto a support mesh plate and then compacted. However, this process is inconvenient and time-consuming when removing the activated carbon. Utility Model Content

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an activated carbon waste gas treatment device applied to the medical waste feeding step, comprising a shell, wherein multiple filter chambers are provided inside the shell, and further comprising a partition mesh plate, a filter groove, a support groove and a fixing and pressing mechanism. The partition mesh plate is fixedly disposed inside the filter chamber, the filter groove is slidably disposed on the partition mesh plate, the support groove is slidably disposed inside the filter groove, and the bottom ends of the filter groove and the support groove are both configured as mesh-like and cut-connected. The fixing and pressing mechanism is detachably disposed inside the support groove for pressing and fixing the support groove and compacting the granular activated carbon inside the support groove.

[0008] Furthermore, the fixing and clamping mechanism includes a clamping frame, a compaction plate, and a quick-release assembly. The clamping frame slides in conjunction with the inner wall of the filter tank. The compaction plate is elastically connected to the clamping frame via an elastic connector. The outer wall of the compaction plate abuts against and slides in conjunction with the inner wall of the bearing groove. The quick-release assembly is disposed within the compaction plate and the bearing groove to fix the compaction plate within the bearing groove.

[0009] Furthermore, the elastic connector includes a telescopic rod and a first spring. Multiple telescopic rods are provided at both ends of the clamping frame. The two ends of the telescopic rods are respectively fixedly connected to one end of the clamping frame and one end of the compaction plate. The first spring is sleeved on the outside of the telescopic rod and is respectively fixedly connected to one end of the clamping frame and one end of the compaction plate.

[0010] As a further embodiment of this solution, the quick-release assembly includes a plug plate, a second spring, and a limiting hemisphere.

[0024] 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.

[0025] Example

[0026] Please see Figures 1 to 7 An activated carbon waste gas treatment device for medical waste feeding process includes a shell 1, a plurality of filter chambers 2 are provided inside the shell 1, the plurality of filter chambers 2 are longitudinally connected, a door is hinged on the filter chamber 2, and also includes a partition mesh plate 3, a filter tank 4, a bearing tank 5 and a fixing and clamping mechanism.

[0027] It should be added that, by setting up an air intake device, the exhaust gas is first introduced into the housing 1 from the bottom of the housing 1 through the front end pipe (usually connected to the temporary storage room for medical waste treatment), and then filtered through multiple filter chambers 2 in sequence.

[0028] A partition screen 3 is fixedly installed inside the filter chamber 2. A filter groove 4 is slidably installed on the partition screen 3. A water-proof groove is slidably installed on the lower side of the partition screen 3 to treat the water vapor carried in the exhaust gas. A handle is provided on the filter groove 4, which can be pulled out horizontally, similar to a drawer. A support groove 5 is slidably installed inside the filter groove 4. The outer wall of the support groove 5 abuts against and slides with the inner wall of the filter groove 4 to support granular activated carbon. The bottom ends of the filter groove 4 and the support groove 5 are both made of mesh and cut to connect them.

[0029] A fixing and clamping mechanism is detachably installed inside the bearing groove 5. It is used to clamp and compact the granular activated carbon inside the bearing groove 5. The fixing and clamping mechanism includes a clamping frame 6, a compaction plate 7, and a quick-release assembly. The clamping frame 6 slides against the inner wall of the filter groove 4. The width of the internal opening of the clamping frame 6 is smaller than the width of the bearing plate. The compaction plate 7 is elastically connected to the clamping frame 6 through an elastic connector. The elastic connector includes a telescopic rod 8 and a first spring 9. Multiple telescopic rods 8 are provided at both ends of the clamping frame 6. The two ends of the telescopic rods 8 are fixedly connected to one end of the clamping frame 6 and one end of the compaction plate 7, respectively. The first spring 9 is fitted onto the telescopic rod. On the outside of 8, the first spring 9 is fixedly connected to one end of the clamping frame 6 and one end of the compaction plate 7 respectively. After the bearing tank 5 is placed in the filter tank 4, granular activated carbon is poured into the bearing tank 5. By holding the clamping frame 6, the compaction plate 7 is moved to the top of the filter tank 4 under the connection of the elastic connector, and the outer wall of the clamping frame 6 moves downward along the inner wall of the filter tank 4. When one end of the clamping frame 6 abuts against one end of the bearing tank 5, the compaction plate 7 is pushed downward to compact a large amount of granular activated carbon. During this process, the telescopic rod 8 and the first spring 9 are stretched. The telescopic rod 8 plays a limiting role for the first spring 9.

[0030] The outer wall of the compaction plate 7 abuts against and slides against the inner wall of the bearing groove 5. A rubber sleeve 17 is fitted on the compaction plate 7, and the rubber sleeve 17 abuts against the inner wall of the bearing groove 5. This can maintain the sealing between the compaction plate 7 and the bearing groove 5. The quick-release assembly is set in the compaction plate 7 and the bearing groove 5 to fix the compaction plate 7 in the bearing groove 5.

[0031] The quick-release assembly includes a connector plate 10, a second spring 12, and a limiting hemisphere 13. Two connector plates 10 are symmetrically slidably arranged at both ends of the compaction plate 7. A handle 18 is fixedly connected to each connector plate 10. Multiple through holes are provided on the compaction plate 7. Slide plates 15 are fixedly connected to both ends of each connector plate 10. A groove 16 that mates with the slide plate 15 is provided on the compaction plate 7. Slots 11 that mate with the connector plates 10 are provided at both ends of the bearing groove 5. Through grooves are provided at both ends of the bearing groove 5. One end of the second spring 12 is fixedly connected to the inner wall of the through groove. One end of the limiting hemisphere 13 is fixedly connected to the other end of the second spring 12. A socket 14 is provided on the connector plate 10, and the limiting hemisphere 13 mates with the socket 14. One end of the connector plate 10 is arc-shaped and mates with the limiting hemisphere 13. When the ball 13 is in conjunction with the compaction plate 7 to compact a large amount of granular activated carbon, the insertion plate 10 and the slot 11 are on the same horizontal line. By holding the two handles 18 and moving them in opposite directions, the handles 18 drive the insertion plate 10 toward the slot 11. The insertion plate 10 slides under the limiting action of the slide plate 15 and the slide groove 16 and is inserted into the slot 11. During this process, one end of the insertion plate 10 abuts against the limiting hemisphere 13 and presses the limiting hemisphere 13 upward. The limiting hemisphere 13 presses the second spring 12 and moves the limiting hemisphere 13 upward into the through groove. When the insertion hole 14 corresponds to the limiting hemisphere 13, the limiting hemisphere 13 moves downward under the elastic force of the second spring 12 and is inserted into the insertion hole 14. In this way, the insertion plate 10 is fixed in the bearing groove 5.

[0032] It should be added that the amount of granular activated carbon poured in each time is quantitatively measured. Therefore, when the compaction plate 7 is in the same position, a large amount of granular activated carbon in the bearing tank 5 can be tightly compacted. At this time, the insertion plate 10 corresponds to the slot 11. It should also be added that when placing the clamping frame 6, you can hold the two handles 18 and keep the handles 18 facing the center of the compaction plate 7 to prevent the insertion plate 10 from sliding. When disassembling the compaction plate 7, simply hold the handles 18 and move them in opposite directions to push the insertion plate 10 to squeeze the limiting hemisphere 13 and move it out of the slot 11. Then, take out the bearing tank 5 and pour out the granular activated carbon.

[0033] Working Principle: This activated carbon waste gas treatment device, applied to the medical waste loading process, treats the waste gas generated by medical waste temporarily stored in the workshop. Before handling the waste gas, the door is opened, the filter tank 4 is pulled out, and the carrying tank 5 is placed inside. Granular activated carbon is then poured into the carrying tank 5. By holding the two handles 18, the compaction plate 7 is moved. The elastic connecting piece of the clamping frame 6 is positioned above the compaction plate 7, causing the outer wall of the clamping frame 6 to move downwards along the inner wall of the filter tank 4. When one end of the clamping frame 6 abuts against one end of the carrying tank 5, the compaction plate 7 is pushed downwards to compact a large amount of granular activated carbon. During this process, the telescopic rod 8 and the first spring 9 are stretched. The telescopic rod 8 acts as a limit for the first spring 9. After the compaction plate 7 has compacted a large amount of granular activated carbon, the insertion plate 10 and the slot 11 are on the same horizontal line. By holding the two handles 18 and moving them in opposite directions... Handle 18 moves the plug plate 10 toward slot 11. Under the limiting action of slide plate 15 and slide groove 16, the plug plate 10 slides and inserts into slot 11. During this process, one end of plug plate 10 abuts against limiting hemisphere 13 and presses the limiting hemisphere 13 upward. The limiting hemisphere 13 presses the second spring 12, and the limiting hemisphere 13 moves upward into the through groove. When the insertion hole 14 corresponds to the limiting hemisphere 13, the limiting hemisphere 13 moves downward under the elastic force of the second spring 12 and inserts into the insertion hole 14. In this way, plug plate 10 is fixed in the bearing groove 5, which keeps the bearing groove 5 stable in the filter groove 4 and makes the compaction plate 7 compact the granular activated carbon. When disassembling the compaction plate 7, simply hold handle 18 and move it in opposite directions to move plug plate 10 to press the limiting hemisphere 13 and move it out of slot 11. Then take out the bearing groove 5 and pour out the granular activated carbon. The operation is simple and the efficiency is improved.
