Separate for last solid storehouse and lower liquid storehouse through setting up filter 13 in the gravity settling chamber, the filtration pore is crossed in the distribution on the filter, only make liquid or less granule pass through, set firmly downwardly extending's first baffle 14 on the roof of going up the solid storehouse, first baffle length is less than the height in last solid storehouse, the setting of first baffle has changed the flow direction of material, the extension material carries out solid-liquid separation's time in the gravity settling chamber, make the separation more thorough, certain contained angle is personally submitted with the level to the bottom surface in lower liquid storehouse, make things convenient for sewage to discharge smoothly.
The top plate of the rough separation chamber is fixedly provided with a second baffle 26 extending downwards, the length of the second baffle is smaller than the height of the rough separation chamber, the first baffle, the second baffle and the second baffle are arranged at intervals to form a cascade type channel, and the cross section of the channel is gradually increased in the flow direction, so that the flow speed is reduced, and deposition is facilitated.
A plurality of cyclone separators 15 are arranged in the water separation chamber, inlets of the cyclone separators are respectively communicated with inlets of the water separation chamber on the second partition plate through pipelines, outlets of the water separation chamber are arranged at the top of the third partition plate, and the bottoms of the cyclone separators are communicated with a liquid collecting tank 16 arranged on a bottom plate of the water separation chamber through liquid discharge pipes. Under normal operating conditions, the drainage pipe and the liquid collecting box are in a communicated state, and when the material box is overturned laterally to discharge the materials, the drainage pipe and the liquid collecting box are in a non-communicated state to prevent liquid in the liquid collecting box from flowing back, and the state is switched to be realized by the stop valve arranged on the drainage pipe.
The smart filter chamber top is equipped with downwardly extending's material board 17 that draws, set up several sack cleaner 18 between material board and the fourth baffle side by side, the length of several sack cleaner is less than the width of smart filter chamber, so that when the material was arranged in the upset of material case side direction, can have certain space to discharge the dust of smart filter chamber filtering smoothly, the export of sack cleaner is linked together with the opening on the fourth baffle, the bottom of sack cleaner is equipped with shale shaker 19, realize the self-cleaning of filter bag through the mode of vibration. The vibrating screen comprises two parallel-arranged herringbone frames 23, four corners of the two herringbone frames are respectively connected with a fourth partition plate and a material guiding plate through springs 24, six nodes of the two herringbone frames are connected with the bottoms of six bag-type dust collectors, the two herringbone frames are provided with vibrators, and when the filter bags are provided with more dust, the dust is shaken off into the fine filter chamber through the vibration of the vibrators.
An induced draft plate 20 is arranged in the noise reduction exhaust chamber, the induced draft plate and the fourth partition plate form an induced draft channel, an air inlet is arranged below the induced draft plate and connected with an inlet of a fan 27, a silencer 21 is arranged at a position close to an exhaust port in the noise reduction exhaust chamber, clean gas flowing out of the fine filter chamber is sucked by the fan, subjected to noise reduction treatment by the silencer and finally discharged out of the vehicle, and a filtering process is completed.
The end faces of one side of the first clapboard and the second clapboard, where the materials flow upwards, are evenly provided with a plurality of spoilers 22 at intervals, and the spoilers are connected with the first clapboard and the second clapboard through an angle adjusting device. The angle adjusting device comprises an articulated piece, a support rod and a hook, the spoiler is articulated with the first partition plate and the second partition plate through the articulated piece, the end surfaces of two sides of the spoiler are respectively articulated with one end of the support rod, and the other end of the support rod is configured with the hook arranged on the first partition plate and the second partition plate. The materials from the gravity settling chamber are guided by the multi-stage channels, when the direction of the fluid is in sharp turn, the materials with larger particles can be effectively settled under the action of inertia, the flow blocking plates on the first and second partition plates incline downwards, the support rods are matched with the hooks below the flow blocking plates, and the flow blocking plates which incline downwards can effectively block part of solid and liquid materials; when the dust accumulation below the spoiler is more after working for a period of time, the spoiler can be swung to drop the accumulated dust into the coarse separation chamber; when the material box overturns laterally to discharge materials, the inclination direction of the spoiler can be adjusted, so that the spoiler is arranged obliquely upwards, and the stay bar is matched with the hook above the spoiler, so that the materials below can be discharged smoothly.
The second partition plate is provided with a discharge valve 25 at a position corresponding to the outlet of the water separation chamber, and the discharge valve is opened when the sucked material is dry and closed when the water content of the material is large. When the water content of the sucked material is larger, the discharge valve is closed, the material enters the cyclone separator and is changed into rotary fluid under the action of the inner cyclone plate, most of liquid, larger solid material and smaller particles adsorbed by the liquid in the material are thrown to the inner wall under the action of centrifugal force, and the liquid and the larger solid material are converged and flow into the liquid collecting tank; when the sucked material is dry, the discharge valve is opened, the pressure drop is reduced a lot, so most of the material directly enters the fine filtering chamber from the coarse separation chamber. The main function of the cyclone separator is to dry the fluid and avoid the blockage caused by the direct entry of the over-wet fluid into the fine filtering chamber.
The above is only a preferred embodiment of the present invention, and certainly, the scope of the present invention should not be limited thereby, and therefore, the present invention is not limited by the scope of the claims.
