Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment, specifically a waste gas treatment device for biological laboratories. Background Technology

[0002] Waste gas generated in laboratory experiments is generally treated using an activated carbon box and a spray tower, with the spray tower typically connected to the output end of the activated carbon box.

[0003] After replacing the activated carbon granules in the existing activated carbon box, the cover needs to be closed. Since some activated carbon granules tend to stay on the top of the partition assembly, the cover may be blocked by the activated carbon assembly when closing, resulting in the cover not closing properly and causing the cover to not close tightly. Utility Model Content

[0004] The purpose of this invention is to provide a biological laboratory waste gas treatment device in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a biological laboratory waste gas treatment device, comprising a box body, an opening at the top of the box body, a cover plate rotatably installed on the upper part of the outer side of the box body to close the opening, a sealing ring installed at the abutment position between the inner circumference of the opening and the cover plate, a discharge mechanism connected to the bottom of the box body, a slot connected to the discharge mechanism on the bottom plate of the box body, and an interception mechanism installed in the inner cavity of the box body.

[0006] As a further embodiment of this utility model: the discharge mechanism includes a discharge pipe fixedly installed at the bottom of the box body. The output end of the discharge pipe is fixedly connected to a sealing plate by studs and nuts. The studs are integrally formed at the four corners of the front end of the discharge pipe. The four corners of the inner side of the sealing plate are provided with round holes for the studs to pass through. The outer wall of the studs is threadedly connected to the nuts. A sealing ring is installed on the mating surface between the front end of the discharge pipe and the sealing plate. The top of the bottom end of the discharge pipe has a guide slope.

[0007] As a further embodiment of this utility model: the interception mechanism includes two sets of partition assemblies equidistantly distributed inside the box. The top of one set of partition assemblies is flush with the bottom of the top plate of the box, and the bottom of the other set of partition assemblies is flush with the top of the bottom plate of the box. The two sets of partition assemblies are staggered and divide the inner cavity of the box into a continuous "S" shaped channel. Each set of partition assemblies consists of multiple partitions.

[0008] As a further embodiment of this utility model: a perforated intercepting net is fixedly installed on the top of the left outer partition plate, which is flush with the top of the bottom of the box body, and the top of the perforated intercepting net is fixedly connected to the bottom of the top plate of the box body.

[0009] As a further embodiment of this utility model: the top of the partition plate, which is flush with the top and bottom of the box body, has a triangular plate, and the bottom of the cover plate is integrally formed with an inner triangular groove mating plate that is opposite to the triangular plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting the triangular plate and the inner triangular groove docking plate, activated carbon can be prevented from remaining on the top of the partition assembly, and the effectiveness of the "S"-shaped channel after the cover is closed can be guaranteed, as well as the sealing performance of the cover.

[0013] 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.

[0014] Please see Figures 1-3 In this embodiment of the present invention, a biological laboratory waste gas treatment device includes a box 1, an opening 7 on the top of the box 1, a cover plate 2 rotatably installed on the upper side of the outer side of the box 1 to close the opening 7, a sealing ring installed at the abutment position between the inner circumference of the opening 7 and the cover plate 2, a discharge mechanism connected to the bottom of the box 1, a slot connected to the discharge mechanism on the bottom plate of the box 1, and an interception mechanism installed in the inner cavity of the box 1.

[0015] In this embodiment: the waste gas generated during the experiment is drawn out by the suction device and enters the interior of the chamber 1 through the pipe. At this time, the activated carbon inside the chamber 1 adsorbs the organic waste gas (such as benzene series waste gas) in the waste gas. When the activated carbon needs to be replaced after a long period of use, the discharge mechanism is opened and the used activated carbon is discharged out through the discharge mechanism. After the used activated carbon has been discharged out, the discharge mechanism is closed. Then, the cover plate 2 is opened and new activated carbon is filled into the chamber 1 until it is completely filled into the interception mechanism. At this time, the cover plate 2 can be closed and locked.

[0016] Please refer to this carefully. Figure 1 The discharge mechanism includes a discharge pipe 3 fixedly installed at the bottom of the housing 1. The output end of the discharge pipe 3 is fixedly connected to a sealing plate 4 through studs and nuts. The studs are integrally formed at the four corners of the front end of the discharge pipe 3. The four corners of the inner side of the sealing plate 4 are provided with round holes for the studs to pass through. The outer wall of the studs is threadedly connected to the nuts. A sealing ring is installed on the mating surface between the front end of the discharge pipe 3 and the sealing plate 4. The bottom end of the discharge pipe 3 has a guide slope 10.

[0017] In this embodiment: when opening the discharge mechanism, a wrench is used to connect with the nut and rotate the nut to disassemble. After the nut is disassembled, the two nuts are disassembled first using the diagonal disassembly method. Then, the wrench is used to disassemble the other two nuts that are rotated outward at the same time. At this time, the activated carbon used acts on the sealing plate 4. At this time, the sealing plate 4 moves and a discharge gap appears, which avoids the activated carbon pressure from deforming the sealing plate 4 during the step-by-step disassembly of the bolts. After the old activated carbon is discharged, use the nut to lock the sealing plate 4, and then you can fill in the new activated carbon granules.

[0018] Please refer to this carefully. Figure 2 and Figure 3 The interception mechanism includes two sets of partition assemblies 6 evenly distributed inside the housing 1. The top of one set of partition assemblies 6 is flush with the bottom of the top plate of the housing 1, and the bottom of the other set of partition assemblies 6 is flush with the top of the bottom plate of the housing 1. The two sets of partition assemblies 6 are staggered and divide the inner cavity of the housing 1 into a continuous "S" shaped channel. Both sets of partition assemblies 6 are composed of multiple partitions. The top of the left outer partition, whose bottom is flush with the top of the bottom of the housing 1, is fixedly installed with a perforated interception net 8. The top of the perforated interception net 8 is fixedly connected to the bottom of the top plate of the housing 1. The top of the partition, whose top is flush with the bottom of the top of the housing 1, has a triangular plate 9. The bottom of the cover plate 2 is integrally formed with an inner triangular groove mating plate 5 that is opposite to the triangular plate 9.

[0019] In this embodiment: after the sealing plate 4 is closed again, the opening 7 is exposed by opening the cover plate 2. Then, new activated carbon particles are filled into the interception mechanism. At this time, the porous interception net 8 can restrict the overflow of activated carbon particles until it is effectively filled. Since the top of the set of partition components 6 has a triangular plate 9, activated carbon particles will not remain on the top of the set of partition components 6. Then, the closed cover plate 2 is rotated to drive the inner triangular groove docking plate 5 to dock with the triangular plate 9. Since the inner triangular groove of the inner triangular groove docking plate 5 matches the triangular plate 9 and a sealing ring is installed at the docking point, the interception performance at the docking point can be guaranteed during the docking process of the inner triangular groove docking plate 5 and the triangular plate 9, and the activated carbon particles can be prevented from affecting the closing of the cover plate 2, thus achieving the purpose of the cover plate 2 being able to close quickly. During the process of exhaust gas entering the housing 1 and being filtered, the "S"-shaped channel formed by the two sets of baffle assemblies 6 can ensure that the exhaust gas moves along the "S"-shaped channel, thereby ensuring the exhaust gas filtration efficiency.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
