Description

Technical Field

[0001] The utility model relates to the technical field of biomass fertilizer production, in particular to filtering equipment for producing biomass fertilizer from methane liquid. Background Art

[0002] Biogas slurry is a by-product of biogas production. It is a high-quality, fast-acting liquid fertilizer rich in amino acids, hydrolytic enzymes, bioactive substances, and a variety of trace elements. It can be used as base fertilizer, topdressing, and foliar fertilizer in fruit and vegetable cultivation. It can not only increase fruit and vegetable yields and improve their quality, but also reduce the occurrence of diseases and pests. In the process of biomass fertilizer production, filtration equipment is needed to filter suspended matter and particulate matter inside the biogas slurry.

[0003] For example, the utility model with application number CN202022023672.8 discloses a new type of biogas slurry filtering device. The utility model clamps the cover plate with the liquid outlet pipe to close the opening of the liquid outlet pipe, and by pouring biogas slurry into the liquid inlet pipe, the biogas slurry passes through the filter screen and accumulates at the bottom of the filter box. The more filtered biogas slurry accumulates, the greater the pressure on the pressure plate, and the pressure plate continuously moves downward, and the pressure plate drives the pry bar to rotate around the first rotating shaft and the second rotating shaft to the cover plate respectively. When the pressure is large enough, the cover plate is pushed open, and the addition of biogas slurry is stopped. The filtered biogas slurry enters the mixing box through the liquid outlet pipe. The volume of the biogas slurry is proportional to the pressure on the pressure plate, and the volume of the filtered biogas slurry entering the mixing box can be controlled. The same volume of water is added to the water storage tank, and the pumping plate is pulled out, and the water enters the mixing box and is mixed with the filtered biogas slurry through the stirring rod to complete the mixing of fertilizers in a 1:1 ratio, thereby saving labor costs. However, after long-term use of this type of filtering device, a layer of impurity particles will accumulate on the filter screen, thereby reducing the amount of biogas slurry passing through, and in severe cases, blockage will occur, resulting in the problem of affecting the filtering efficiency of the equipment.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a filtering device for producing biomass fertilizer from biogas liquid is provided. Utility Model Content

[0012] The utility model provides a filtering device for producing biomass fertilizer from biogas liquid, which has the following

[0013] Beneficial effects:

[0014] 1. The utility model can filter the biogas slurry by using the arc-shaped filter plate during the biogas slurry filtering process through the setting of the cleaning component, and when impurities accumulate on the top of the filter plate, the motor will drive the swing arm to swing back and forth through the synchronous shaft. At this time, since the first magnet will adsorb the second magnet, it can drive the slide seat to move inside the guide groove, so that the brush plate can sweep the impurity particles on the filter plate to both sides, preventing the impurities from accumulating on the filter plate and affecting the efficiency of biogas slurry filtering. In addition, the swing arm and the slide seat are driven by magnetic attraction, so the sealing performance of the equipment can be improved, and the leakage of biogas slurry can be reduced;

[0015] 2. The utility model can collect the swept impurities through the setting of the aggregate frame, and during use, the rotating block will limit one side of the sealing plate, and the rubber sealing strip will seal the sealing plate and the shell under the action of deformation, and the sealing sleeve containing an O-ring inside can also seal the slide bar and the sealing plate to avoid leakage. Before unloading, when the internal biogas slurry passes through the filter plate, some biogas slurry will accumulate in the aggregate frame. At this time, after the internal impurities are precipitated, the slide bar can be slowly pushed to change the internal volume of one end of the aggregate frame, and the excess biogas slurry inside can be squeezed onto the filter plate. After reciprocating sliding, the biogas slurry inside the aggregate frame will be reduced, thereby avoiding the situation where the internal biogas slurry is too full and easily spilled when disassembling the aggregate frame. At the same time, during disassembly, it is only necessary to rotate the rotating block forcefully to release the restriction on the outside of the sealing plate, so that disassembly is also very convenient.
