Description

Technical Field

[0001] The utility model relates to the technical field of sludge dehydration devices, in particular to a sludge dehydration device for beer wastewater treatment. Background Art

[0002] Brewery wastewater is the main source of pollution in breweries. It mainly comes from: the cleaning of raw wheat, malt culture and old bottle washing wastewater, as well as the wastewater discharged during the brewing process, which mainly contains organic matter such as sugars and alcohols. The activated sludge method is the most commonly used and most reliable method for treating brewery wastewater. After the wastewater enters the aeration tank, it is mixed with activated sludge (containing a large number of aerobic microorganisms). Under artificial oxygenation conditions, the activated sludge adsorbs and oxidizes and decomposes the organic matter in the wastewater.

[0003] Biological treatment of brewery wastewater will produce a large amount of residual sludge. The first and most critical step in the treatment of residual sludge is dehydration. The purpose of sludge dehydration is to reduce the moisture content of the sludge and convert the sludge from liquid to solid to facilitate subsequent treatment.

[0004] At present, the sludge dewatering of breweries mostly uses plate-type sludge dewatering machines or spiral extrusion sludge dewatering machines, but there are the following problems in use: because the sludge of breweries has sugar content and contains wheat husk residue, the filter screen and filter cloth of traditional sludge dewatering machines are easy to clog and difficult to clean and maintain frequently, and the wheat husk residue remaining in the dewatered water is also easy to clog the pipeline. Therefore, this application proposes a sludge dewatering device for brewery wastewater treatment. Utility Model Content

[0007] Furthermore, the water filtering mesh is composed of transverse strip through holes 1 uniformly opened at the bottom of the extrusion cylinder and longitudinal strip through holes 2 uniformly opened on the water filtering plate.

[0008] Furthermore, a plurality of protrusions are evenly arranged on the water filter plate, the protrusions matching the depth of the strip-shaped through holes.

[0009] Furthermore, the filter tank is suspended in the drainage tank through ear plates on both sides of the top, and the bottom of the drainage tank is a bucket-shaped water outlet.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The present application forms a water filter mesh by detachably installing a water filter plate on the bottom of the extrusion cylinder, and the water filter mesh is composed of a horizontal strip through hole one evenly opened at the bottom of the extrusion cylinder and a longitudinal strip through hole two evenly opened on the water filter plate. Compared with the traditional independently opened fine mesh, the mesh of the present application will not be blocked and is easy to disassemble and clean, which solves the problem that the sludge in the brewery has sugar content and contains wheat husk residue, and the filter screen and filter cloth are easy to be blocked and difficult to clean.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technicians.

[0019] The utility model discloses a sludge dehydration device for treating beer wastewater. Figure 1-4A sludge dehydration device for beer wastewater treatment includes a frame 1, a motor 2, a coupling 3, a screw shaft 4, a spiral blade 5, a shell 6, a filter tank 7, and a drainage tank 8; the motor 2 is installed at one end of the frame 1, the power output end of the motor 2 is connected to the screw shaft 4 through the coupling 3, the other end of the screw shaft 4 is installed on the bearing seat, the spiral blade 5 is installed on the screw shaft 4, the shell 6 is arranged on the outside of the screw shaft 4 and installed on the frame 1, the two ends and the middle of the shell 6 are respectively a feed cylinder 61, a discharge cylinder 62 and an extrusion cylinder 63, the water filter plate 9 is detachably installed at the bottom of the extrusion cylinder 63 to form a water filter mesh 60, the filter tank 7 is arranged in the drainage tank 8 and is installed on the frame 1 below the extrusion cylinder 63.

[0020] The motor 2 installed on the frame 1 can drive the screw shaft 4 to rotate through the power output end and the coupling 3. The diameter of the screw shaft 4 gradually increases from the feed barrel 61 to the discharge barrel 62. The spiral blades 5 installed on the screw shaft 4 are externally fitted with the shell 6. The sludge input through the feed barrel 61 can be pushed forward by the spiral blades 5 from the feed barrel 61 to the extrusion barrel 63 and the discharge barrel 62. Since the diameter of the screw shaft 4 gradually increases, the space of the sludge is continuously reduced during the pushing process, and the sludge is extruded and dehydrated and then discharged from the discharge barrel 62, and the dehydrated water is discharged through the water filter mesh 60 at the bottom of the extrusion barrel 63. The water filter mesh 60 is jointly composed of the water filter plate 9 and the bottom of the extrusion barrel 63. The mesh will not be blocked and is easy to disassemble and clean. This solves the problem that the sludge in the brewery has sugar content and contains wheat husk residue, and the filter screen and filter cloth are easily blocked and difficult to clean. The water discharged from the water filtering mesh 60 enters the filter tank 7 and is then discharged from the drainage tank 8. The husk residue can be collected in the filter tank, thus solving the problem that the husk residue remaining in the discharged water is prone to block the pipeline.

[0021] See also Figure 1-4 The water filter mesh 60 is composed of a transverse strip through hole 1 64 evenly opened at the bottom of the extrusion cylinder 63 and a longitudinal strip through hole 2 91 evenly opened on the water filter plate 9. Compared with the traditional fine mesh holes opened independently, the mesh holes composed of the longitudinal strip through holes are not easy to be blocked, and are easy to disassemble and clean. The size of the filtration gap can be controlled by replacing the water filter plate 9 with different opening densities, which is convenient for maintenance.

[0022] See also Figure 1-4 The water filter plate 9 is evenly provided with a plurality of protrusions 92 that match the depth of the strip-shaped through hole 64, which can form a relatively smooth mesh wall surface in the shell 6 and is not easy to accumulate sludge.

[0023] See also Figure 1-4 The filter tank 7 is suspended in the drainage tank 8 through ear plates 71 on both sides of the top, which is convenient for filtering out and cleaning wheat husk residues. The bottom of the drainage tank 8 is a bucket-shaped water outlet 81 for easy drainage.

[0024] Working process:

[0025] Before dehydration, a water filter plate 9 with a suitable opening density is installed at the bottom of the extrusion cylinder 63 according to the filtering requirements, and the motor 2 is started to drive the spiral shaft 4 to rotate. The sludge enters the shell 6 through the feed cylinder 61 and is pushed forward by the spiral blade 5 to the extrusion cylinder 63 and the discharge cylinder 62. During the pushing process, the space is continuously reduced and the sludge is squeezed and dehydrated and then discharged from the discharge cylinder 62. The desorbed water is discharged into the filter tank 7 through the water filter mesh 60 at the bottom of the extrusion cylinder 63 and is discharged from the drainage tank 8 after filtration. The water filter plate 9 is regularly disassembled to clean the strip through hole 1 64 and the strip through hole 2 91, and the filter tank 7 is regularly taken out to clean the collected wheat husk residue.

[0026] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
