Description

Technical Field

[0001] This utility model relates to the field of chemical wastewater treatment technology, specifically a biological treatment device for chemical wastewater. Background Technology

[0002] Industrial wastewater contains many organic and harmful substances. These substances can be treated by simple filtration, so microbial degradation is generally used for treatment. Microbial degradation is a wastewater treatment technology based on the field of biochemistry for environmental protection. By introducing a certain amount of beneficial microorganisms into the wastewater, the harmful substances are decomposed and then aggregated and precipitated at the bottom of the degradation tank. The precipitate is then dredged and removed, thereby achieving the effect of purifying the water quality. However, the existing removal methods generally rely on manual dredging of the precipitate, which is relatively inefficient.

[0003] In the prior art, CN219409417U discloses a microbial degradation device for industrial wastewater treatment. This device uses the lifting effect of filter plates to elevate and remove sediment accumulated at the bottom after microbial degradation. This significantly improves the efficiency of sediment removal, allowing workers to simply remove the sediment from the filter plates without having to manually retrieve it from the water, thus greatly improving work quality and cleaning effectiveness. However, the filter plates are difficult to disassemble. In actual use, after multiple uses, the filter plates require cleaning, replacement, or repair. The difficulty in disassembling the filter plates increases the difficulty and time cost of equipment maintenance. Therefore, this invention proposes a biological treatment device for chemical wastewater to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a biological treatment device for chemical wastewater 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 treatment device for chemical wastewater, comprising a degradation tank, and further comprising: a support frame plate located at the upper end of the degradation tank for mounting an electric telescopic rod, wherein a connecting block is mounted on the output end of the electric telescopic rod; a retrieval mechanism disposed inside the degradation tank for retrieval of sediment, wherein an mounting block is disposed on the retrieval mechanism; and a double-sided limiting mechanism mounted on the mounting block for simultaneously limiting both sides of the connecting block, thereby fixing the connecting block and the mounting block together and facilitating the installation and disassembly of the connecting block and the mounting block.

[0006] Preferably, the mounting block has a mounting groove into which the connecting block extends.

[0007] Preferably, the dual-sided limiting mechanism includes a mounting flat seat fixedly mounted on the mounting block, a bidirectional threaded rod rotatably disposed inside the mounting flat seat, and a knob mounted on the bidirectional threaded rod.

[0008] Preferably, the bidirectional threaded rod is symmetrically provided with movable connecting plates, and the movable connecting plates are slidably connected to sliding guide rods. The sliding guide rods are fixedly connected to the mounting block, and both movable connecting plates are threadedly connected to the bidirectional threaded rod.

[0009] Preferably, the bidirectional threaded rod is used to drive the two movable connecting plates to move closer to each other or further apart, and a limit plate is fixedly connected to each of the two movable connecting plates.

[0010] Preferably, the limiting insert is slidably connected to the mounting block, and the mounting block has a slot for the limiting insert to extend into.

[0011] Preferably, the retrieval mechanism includes a lifting filter plate that is slidably disposed inside the degradation tank.

[0012] Preferably, the salvage mechanism includes a connecting frame fixedly installed on the lifting filter plate, and an mounting block is fixedly installed on the connecting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] With a double-sided limiting mechanism, when the lifting filter plate needs cleaning and maintenance, turning the knob allows the two limiting plates to move out of the slots, thereby releasing the restriction on the connecting block. The connecting block can then be removed from the mounting slot, enabling the lifting filter plate to be disassembled, facilitating cleaning and maintenance and improving convenience. When the lifting filter plate needs to be installed, the connecting block is inserted into the mounting slot, and the bidirectional threaded rod is rotated in the opposite direction, allowing the two limiting plates to extend into the slots respectively, limiting and fixing the two sides of the connecting block, thus improving stability.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a biological treatment device for chemical wastewater, including a degradation tank 1, and further including: a support frame 2, located at the upper end of the degradation tank 1, for mounting an electric telescopic rod 3, with a connecting block 4 mounted on the output end of the electric telescopic rod 3; a retrieval mechanism, located inside the degradation tank 1, for retrieval of sediment, with an mounting block 5 mounted on the retrieval mechanism; and a double-sided limiting mechanism 6, mounted on the mounting block 5, for simultaneously limiting both sides of the connecting block 4, thereby fixing the connecting block 4 and the mounting block 5, facilitating the installation and disassembly of the connecting block 4 and the mounting block 5. The side limiting mechanism 6 allows the two limiting plates 65 to be removed from the slots 66 when the lifting filter plate 9 needs cleaning and maintenance. This releases the restriction on the connecting block 4, allowing it to be removed from the mounting slot 7 and thus enabling the disassembly of the lifting filter plate 9. This facilitates cleaning and maintenance of the lifting filter plate 9 and improves convenience. When the lifting filter plate 9 needs to be installed, the connecting block 4 is inserted into the mounting slot 7, and the bidirectional threaded rod 61 is rotated in the opposite direction. This allows the two limiting plates 65 to be inserted into the slots 66 respectively, limiting and fixing the two sides of the connecting block 4, thus improving stability.

[0022] Please see Figure 2 and Figure 3The mounting block 5 has a mounting groove 7 for the connecting block 4 to extend into. The double-sided limiting mechanism 6 includes a mounting flat seat 62 fixedly mounted on the mounting block 5. A bidirectional threaded rod 61 is rotatably mounted inside the mounting flat seat 62. A knob is mounted on the bidirectional threaded rod 61. A movable connecting plate 63 is symmetrically arranged on the bidirectional threaded rod 61. A sliding guide rod 64 is slidably connected inside the movable connecting plate 63. The sliding guide rod 64 is fixedly connected to the mounting block 5. Both movable connecting plates 63 are threadedly connected to the bidirectional threaded rod 61. The bidirectional threaded rod 61 is used to drive the two movable connecting plates 63 to move closer or further apart. A limiting insert plate 65 is fixedly connected to both movable connecting plates 63. The limiting insert plate 65 is slidably connected to the mounting block 5. The connecting block 4 has a slot 66 for the limiting insert plate 65 to extend into.

[0023] Please see Figure 1 and Figure 4 The retrieval mechanism includes a lifting filter plate 9 that is slidably disposed inside the degradation tank 1, and a connecting frame 8 that is fixedly installed on the lifting filter plate 9, with an installation block 5 fixedly installed on the connecting frame 8.

[0024] In actual use, a certain amount of beneficial microorganisms are introduced into the degradation tank 1 to cause the harmful substances in the industrial wastewater to quickly aggregate and precipitate, thereby completing the degradation work of the wastewater by microorganisms. This process is a publicly available technology and will not be described in detail here.

[0025] When it is necessary to dredge and clean the accumulated sediment, the electric telescopic rod 3 is retracted, which moves the lifting filter plate 9 upward to dredge the sediment. When the lifting filter plate 9 needs cleaning and maintenance, the knob is turned to rotate the bidirectional threaded rod 61 on the mounting flat seat 62. The rotation of the bidirectional threaded rod 61 drives the two moving connecting plates 63 to move away from each other. The two moving connecting plates 63 drive the two limiting inserts 65 to move away from each other, so that the two limiting inserts 65 are removed from the slots 66, thereby releasing the restriction on the connecting block 4. The connecting block 4 can then be removed from the placement slot 7, thereby disassembling the lifting filter plate 9 and facilitating cleaning and maintenance of the lifting filter plate 9, thus improving convenience. When it is necessary to install the lifting filter plate 9, the connecting block 4 is inserted into the placement slot 7, and the bidirectional threaded rod 61 is rotated in the opposite direction, so that the two limiting inserts 65 are inserted into the slots 66 respectively, limiting and fixing the two sides of the connecting block 4, thus improving stability.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
