Description

Technical Field

[0001] This utility model belongs to the field of wastewater filtration technology, and specifically relates to a wastewater filter. Background Technology

[0002] Wastewater filters are an indispensable device in pipelines transporting media. They are used to remove impurities, suspended solids, bacteria, and other harmful substances from wastewater, thereby purifying the water and reducing the difficulty of wastewater treatment. However, current technologies for wastewater filtration typically use mesh filter media or screens to remove larger particles and solid particles through physical barriers. This method is prone to clogging, requiring periodic shutdowns for cleaning, which can reduce wastewater treatment efficiency and increase the workload of staff.

[0003] Therefore, it is necessary to provide a wastewater filter to address the aforementioned technical problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a sewage filter that can solve the problem of easy clogging in existing sewage filters.

[0006] To achieve the above objectives, a specific embodiment of the present invention provides a wastewater filter, comprising: a filter housing, a spiral sedimentation mechanism, and a filtration and purification mechanism;

[0007] The spiral sedimentation mechanism is installed inside the filter housing. The spiral sedimentation mechanism includes a fixed column block, a spiral slide plate is fixedly installed between the fixed column block and the filter housing, a vertical sealing plate is fixed to one end of the spiral slide plate, multiple storage cylinders are installed on the fixed column block, and a rotation control ball is installed at one end of each storage cylinder.

[0008] The filtration and purification mechanism is installed below the fixed column block. The filtration and purification mechanism includes a second support partition plate, on which multiple conveying pipes are installed. A filtration and purification cylinder is sleeved on the conveying pipes, and the portion of the conveying pipes located inside the filtration and purification cylinder has multiple evenly distributed through holes.

[0009] In one or more embodiments of this utility model, the filter housing is provided with a top cover for sealing the upper end of the filter housing and for easy disassembly and installation by workers, thereby facilitating the maintenance of the device. The filter housing is provided with a decontamination groove, and a side cover is provided in the decontamination groove for easy cleaning of impurities filtered down the sliding inclined plate and to avoid the accumulation of impurities.

[0010] In one or more embodiments of this utility model, a sewage discharge pipe and a sewage inlet pipe are fixedly installed on the filter housing. The sewage discharge pipe is used to discharge the filtered sewage, and the sewage inlet pipe is used to pass the sewage into the filter housing for convenient filtration and purification.

[0011] In one or more embodiments of this utility model, a first support partition is fixed to the lower end of the fixed column block to support the fixed column block and prevent the fixed column block from falling off. Multiple drain pipes are installed on the first support partition to allow sewage to flow downwards, so that the sewage can be filtered through the sliding inclined plate and the screen holes.

[0012] In one or more embodiments of this utility model, the storage cylinder stores flocculant. By adding flocculant to wastewater, impurities in the wastewater can gradually aggregate into large particles, thereby facilitating filtration and discharge.

[0013] In one or more embodiments of this utility model, a sliding inclined plate is fixedly installed below the first supporting partition plate. The sliding inclined plate has a plurality of evenly distributed screen holes for filtering sewage, thereby making it less likely for sewage to become clogged in subsequent filtration and purification, and improving the filtration and purification efficiency of sewage.

[0014] In one or more embodiments of this utility model, a fixing block is fixedly connected between the plurality of filter purification cartridges and the inner wall of the filter housing to fix the filter purification cartridges and prevent the filter purification cartridges from falling off.

[0015] In one or more embodiments of this utility model, a main drive shaft is also inserted into the second support partition for supporting the drive gear and driving the drive gear to rotate. The bottom end of the main drive shaft is connected to an external drive device, thereby enabling the main drive shaft to rotate.

[0016] An upper support bearing is fixedly connected between the main drive shaft and the second support partition. A fixed base block is fixed on the bottom wall of the filter housing. A lower support bearing is fixedly connected between the fixed base block and the main drive shaft. This is used to stabilize the main drive shaft, making it less prone to shaking or tilting, and ensuring the stability of the device operation.

[0017] In one or more embodiments of this utility model, a drive gear is fixed on the main drive shaft, and driven gears are fixed on the multiple conveying pipes. The drive gear and the multiple driven gears mesh with each other. The drive gear drives the multiple driven gears to rotate, thereby causing the multiple conveying pipes to rotate. This allows the sewage conveyed downward through the conveying pipes to impact the inner wall of the filter purification cylinder, thus making the filter purification cylinder less prone to clogging.

[0018] In one or more embodiments of this utility model, a fixed bearing and a sealing sleeve are respectively connected between the conveying pipe, the second supporting partition, and the filter purification cylinder. The sealing sleeve is used to seal the wastewater so that it can only flow downward through the filter purification cylinder.

[0019] Compared with the prior art, this utility model, through the setting of the corresponding mechanism, makes the sewage filter less prone to clogging, thereby reducing the frequency of cleaning by staff, less likely to affect the operation of the equipment, less likely to reduce sewage treatment efficiency and lessen the labor intensity of staff.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0029] like Figures 1 to 5 As shown, a wastewater filter in one embodiment of the present invention includes: a filter housing 1, a spiral sedimentation mechanism 2, and a filtration and purification mechanism 3.

[0030] like Figures 1 to 3 As shown, a top cover 101 is provided on the filter housing 1 to seal the upper end of the filter housing 1, and to facilitate disassembly and installation by personnel, thereby facilitating the maintenance of the device. A decontamination groove is cut into the filter housing 1, and a side cover 102 is provided in the decontamination groove to facilitate the cleaning of impurities filtered down from the sliding inclined plate 208 and to prevent the accumulation of impurities.

[0031] Specifically, a sewage discharge pipe 103 and a sewage inlet pipe 104 are fixedly installed on the filter housing 1. The sewage discharge pipe 103 is used to discharge the filtered sewage, and the sewage inlet pipe 104 is used to pass the sewage into the filter housing 1 for convenient filtration and purification.

[0032] like Figures 1 to 4As shown, the spiral sedimentation mechanism 2 is installed inside the filter housing 1. The spiral sedimentation mechanism 2 includes a fixed column block 201 for supporting multiple storage cylinders 204 and cooperating with the spiral slide plate 202 to guide the sewage. The spiral slide plate 202 is fixedly installed between the fixed column block 201 and the filter housing 1 to guide the flow of sewage. A vertical sealing plate 203 is fixed to one end of the spiral slide plate 202.

[0033] like Figures 1 to 4 As shown, multiple storage cylinders 204 are installed on the fixed column block 201. A rotation control ball 205 is installed at one end of each storage cylinder 204. By rotating the rotation control ball 205, the flocculant inside the storage cylinder 204 can leak out through the gap between the rotation control ball 205 and the storage cylinder 204. The storage cylinder 204 stores flocculant. By adding flocculant to wastewater, impurities in the wastewater can gradually aggregate into large particles, thus facilitating filtration and discharge.

[0034] like Figures 1 to 5 As shown, a first support partition 206 is fixed to the lower end of the fixed column block 201 to support the fixed column block 201 and prevent the fixed column block 201 from falling off. Multiple drain pipes 207 are installed on the first support partition 206 to allow sewage to flow downwards, so that the sewage can be filtered through the sliding inclined plate 208 and the screen hole 209.

[0035] Specifically, a sliding inclined plate 208 is fixedly installed below the first support partition 206. The sliding inclined plate 208 has multiple evenly distributed screen holes 209 for filtering sewage, so that the sewage is less likely to be blocked in subsequent filtration and purification, thereby improving the filtration and purification efficiency of sewage.

[0036] like Figures 1 to 5 As shown, the filtration and purification mechanism 3 is installed below the fixed column block 201. The filtration and purification mechanism 3 includes a second support partition 301, on which multiple conveying pipes 302 are installed. Filter purification cylinders 303 are sleeved on the conveying pipes 302. The portion of the conveying pipes 302 located inside the filter purification cylinders 303 has multiple evenly distributed through holes 304. Each of the multiple filter purification cylinders 303 is fixedly connected to the inner wall of the filter housing 1 by a fixing block 305 to fix the filter purification cylinders 303 and prevent them from falling off.

[0037] like Figures 1 to 5As shown, a main drive shaft 313 is also inserted into the second support partition 301 to support the drive gear 309 and drive the drive gear 309 to rotate. The bottom end of the main drive shaft 313 is connected to an external drive device, thereby enabling the main drive shaft 313 to rotate. An upper support bearing 310 is fixedly connected between the main drive shaft 313 and the second support partition 301. A fixing block 311 is fixedly fixed on the bottom wall of the filter housing 1. A lower support bearing 312 is fixedly connected between the fixing block 311 and the main drive shaft 313 to stabilize the main drive shaft 313, preventing it from shaking or tilting and ensuring the stability of the device operation.

[0038] like Figures 1 to 5 As shown, a drive gear 309 is fixed on the main drive shaft 313, and driven gears 308 are fixed on multiple conveying pipes 302. The drive gear 309 and multiple driven gears 308 mesh with each other. The drive gear 309 drives the multiple driven gears 308 to rotate, thereby causing the multiple conveying pipes 302 to rotate. This allows the sewage conveyed downward by the conveying pipes 302 to impact the inner wall of the filter purification cylinder 303, thus making the filter purification cylinder 303 less prone to clogging.

[0039] like Figures 1 to 5 As shown, a sealing sleeve 307 is fixedly connected between the conveying pipe 302 and the filter purification cylinder 303 to provide a seal, ensuring that sewage can only flow downwards through the filter purification cylinder 303. A drive gear 309 is fixed on the main drive shaft 313, and driven gears 308 are fixed on each of the multiple conveying pipes 302. The drive gear 309 meshes with the multiple driven gears 308, causing the drive gear 309 to drive the multiple driven gears 308 to rotate, thereby causing the multiple conveying pipes 302 to rotate. This allows the sewage conveyed downwards through the conveying pipes 302 to impact the inner wall of the filter purification cylinder 303, thus preventing clogging. A fixed bearing 306 and a sealing sleeve 307 are respectively connected between the conveying pipe 302, the second support partition 301, and the filter purification cylinder 303. The sealing sleeve 307 provides a seal, ensuring that sewage can only flow downwards through the filter purification cylinder 303.

[0040] In practical use, sewage is delivered into the filter housing 1 through the sewage inlet pipe 104, causing the sewage to flow downwards along the spiral slide plate 202. During the flow of the sewage, the rotating control ball 205 will also rotate, causing the flocculant stored in the storage cylinder 204 to flow out. The flocculant will cause the impurities in the sewage to aggregate into large particles, which then flow downwards through multiple drain pipes 207 and are filtered by the sliding inclined plate 208 and the sieve holes 209, so that the large particles can be screened out.

[0041] The wastewater then flows downwards through multiple conveying pipes 302, and is connected to an external drive device at the lower end of the main drive shaft 313, which drives the drive gear 309 to rotate. The drive gear 309 then drives multiple driven gears 308 to rotate, thereby causing the multiple conveying pipes 302 to rotate. The wastewater is then filtered through the filter purification cylinder 303 and finally discharged outwards through the wastewater discharge pipe 103. By removing the side cover 102, the staff can clean the impurities filtered down on the sliding inclined plate 208.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
