Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a desilting, diversion and drainage mechanism for anaerobic sewage treatment equipment. Background Art

[0002] Hospital wastewater, also known as medical sewage, mainly refers to the wastewater generated by the hospital during its operation. Hospital wastewater mainly comes from various operating links of the hospital, including but not limited to consulting rooms, laboratories, wards, laundries, etc. These wastewaters may contain various pathogens, such as pathogenic bacteria, viruses and parasites, as well as harmful substances such as chemicals and radioactive isotopes. Complex composition: Hospital wastewater contains not only common pollutants in domestic sewage, but also acids, alkalis, suspended solids, BOD, COD, and toxic and harmful substances such as animal and plant oils. High content of pathogenic microorganisms: Due to the particularity of medical activities, hospital wastewater often contains a large number of pathogenic microorganisms, such as bacteria, viruses, etc. Potential radioactive pollution: Some medical activities may produce radioactive wastewater, which poses a special threat to human body and the environment. This includes the use of anaerobic equipment to treat hospital wastewater.

[0003] Anaerobic sewage treatment equipment is an efficient and environmentally friendly sewage treatment device, which is widely used in industrial wastewater treatment and urban sewage treatment. The working principle of anaerobic sewage treatment equipment is mainly to decompose organic matter in wastewater into gases such as carbon dioxide and methane through the action of anaerobic bacteria. Hydrolysis stage: macromolecular organic matter is decomposed into small molecular organic matter under the action of microorganisms. Acidification stage: small molecular organic matter is further decomposed into fatty acids, alcohols and other substances under the action of acidifying bacteria. Hydrogen and acetic acid production stage: fatty acids, alcohols and other substances are converted into hydrogen, acetic acid and carbon dioxide. Methanation stage: hydrogen and carbon dioxide are converted into methane and water under the action of methanogenic bacteria. During the treatment process, sludge needs to be discharged.

[0004] When discharging sludge from anaerobic treatment equipment, it is necessary to ensure the sludge discharge rate and facilitate subsequent transportation. However, we consider that when transporting sludge, directly transporting the sludge discharged from the anaerobic equipment will cause the sludge to be too heavy and occupy a large amount of transportation space when discharged, increasing the transportation cost and being inconvenient. Therefore, there is an urgent need for a dredging, diversion and drainage mechanism for anaerobic sewage treatment equipment to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a desilting, diversion and drainage mechanism for anaerobic sewage treatment equipment, which solves the problem in the prior art that when transporting sludge, the sludge discharged from the anaerobic equipment is directly transported. Since the sludge contains a large amount of water, it will be too heavy when discharged, and a large amount of transportation space will be occupied, thereby increasing the transportation cost.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] An air pump is fixedly connected to one side of the outer wall of the frame by screws, a side tube is fixedly connected to one side of the frame, and a connecting tube is fixedly connected to one side of the inner upper part of the frame, a plurality of extrusion airbags are connected to the bottom of the connecting tube, and all the extrusion airbags are respectively located between every two of all the extrusion plates, and a push plate is provided on the other side between every two of all the extrusion plates, one side of all the push plates are fixedly connected to a push airbag, one side of all the push airbags are fixedly connected to a fixed frame, and one side of all the push airbags are interconnected with one side of the side tube, and the tops between two adjacent ones of all the extrusion plates are fixedly connected by a connecting chain, a cylinder is fixedly connected to one side of the outer wall of the frame by bolts, and the output shaft of the cylinder passes through the side wall of the frame and is fixedly connected with one side of one of the extrusion plates, and the air outlet of the air pump is respectively interconnected with the top of the connecting tube and one side of the side tube.

[0009] Preferably, all the extrusion plates are grouped in pairs, and the bottom of one of the extrusion plates in each group is fixedly connected to a load-bearing leak plate, and the bottom of the other extrusion plate is fixedly connected to a docking frame used in conjunction with the load-bearing leak plate.

[0010] Preferably, the tops of all the extruded airbags are connected to each other through connecting pipes and the bottoms of the connecting pipes, and valve bodies are installed on all the connecting pipes.

[0011] Preferably, one side of all the propulsion airbags is connected to each other through the trachea and one side of the side tube.

[0012] Preferably, sliders are fixedly connected to both sides of the filter plate, and the sliders are slidably connected to the inner wall of the frame through slide rails.

[0013] Preferably, a handle is fixedly connected to one side of the filter plate, and the handle passes through the side wall of the frame through the bearing groove.

[0014] Preferably, a side groove is provided on one side of the frame close to the side tube, the connection between the output shaft of the cylinder and the frame is a sliding connection, the inlet of the sludge pump is connected to a feed pipe, and the feed port of the feed pipe is connected to the inner lower part of the supporting frame, the bottom sides of the discharge pipe are connected to discharge heads, and several discharge ports at the bottom of the two discharge heads are respectively located between two of each group of extrusion plates.

[0015] The present invention has at least the following beneficial effects:

[0016] When the desilting, diverting and draining mechanism of the anaerobic sewage treatment equipment of the present invention is used, first, the sludge discharged from the anaerobic sewage treatment equipment is discharged into the carrying frame, the sludge pump is started to pump the sludge in the carrying frame into the discharge pipe, and then the sludge is squeezed between two of each group of extrusion plates, and at the same time, each group of extrusion plates is separated by a cylinder and a connecting chain, so that there is a certain gap between each group of extrusion plates. When a certain amount of sludge is discharged between the two extrusion plates, the sludge pump is stopped, and the cylinder is started to drive all the extrusion plates to approach each other to squeeze the sludge, so that water in the sludge can be squeezed out to separate the sludge from the liquid, and the water will fall on the inner bottom of the frame;

[0017] Then, the sludge between each group of two squeezing plates is pushed out from between the two squeezing plates by using a pushing airbag and a squeezing airbag, that is, the air pump is started to pass gas into all the pushing airbags to expand the pushing airbags to push the sludge between the two squeezing plates to the other side, and then the squeezing airbags are opened so that the gas in the air pump pushes the sludge downward through the squeezing airbags, thereby pushing the sludge to fall on the top of the filter plate, and at the same time, the extended length of the pushing airbag will only be squeezed out by the squeezing airbag and will not affect the downward movement of the squeezing airbag. At this time, the sludge and water can be separated. Compared with the prior art, when transporting sludge, the sludge discharged from the anaerobic equipment is directly transported, because it contains a large amount of water, which will lead to the problem of excessive weight when discharged, occupying a large amount of transportation space, and increasing transportation costs. The method proposed in the present invention squeezes the sludge by bringing the squeezing plates close to each other to squeeze the sludge, so that the water in the sludge can be squeezed out, and then the sludge is pushed out from between the two squeezing plates by using the pushing airbag and the squeezing airbag, so that the sludge can be quickly discharged.

[0018] The present invention also has the following beneficial effects:

[0019] By utilizing all the connecting chains, all the extrusion plates can be separated to a certain extent after the extrusion operation is performed under the drive of the contraction of the cylinder, and the connecting chains are used as the limiting length of the separation between the extrusion plates.

[0020] When a certain amount of sludge falls on the filter plate, the filter plate is manually pulled out of the frame, so that the separated sludge can be taken out of the frame and the filter plate can be reinserted for subsequent use. At the same time, the bottom valve can be opened to discharge the water at the bottom of the frame.

[0021] By bringing two of the extrusion plates in each group close to each other, the supporting leak plate can be inserted into the docking frame to ensure that the bottom of the extrusion plate supports the sludge and prevent the sludge from falling without being dehydrated. At the same time, when the sludge needs to fall onto the filter plate, the supporting leak plate can cooperate with the extrusion airbag to squeeze the sludge out. BRIEF DESCRIPTION OF THE DRAWINGS
