Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a self-cleaning multi-layer filter structure for laboratory wastewater treatment. Background Technology

[0002] The self-cleaning multi-layer filtration structure for laboratory wastewater treatment is an integrated filtration device specifically designed for treating laboratory wastewater with complex composition and containing a large amount of suspended solids and dissolved organic matter. Its core function is to remove solid particulate impurities and dissolved pollutants from the wastewater through a multi-stage treatment method that combines physical filtration and adsorption purification, thereby achieving wastewater purification and compliance with discharge standards. This structure typically includes a pre-screen filtration layer and a post-activated carbon adsorption layer, and integrates an automatic cleaning function to maintain the long-term stable operation of the equipment.

[0003] Existing self-cleaning multi-layer filtration structures for laboratory wastewater treatment still have some problems during use. For example, traditional activated carbon layers are mostly fixed in the equipment. In actual operation, the activated carbon is immersed in wastewater for a long time. Under the combined effects of hydraulic pressure difference, pollutant deposition, and its own physicochemical properties, it is very easy for caking to occur. This causes the wastewater to not pass through the activated carbon layer evenly, forming channels. As a result, most of the activated carbon cannot come into contact with pollutants, and the effective adsorption area is reduced.

[0004] To address these issues, we offer a self-cleaning multi-layer filtration structure for laboratory wastewater treatment. Utility Model Content

[0005] The purpose of this invention is to provide a self-cleaning multi-layer filtration structure for laboratory wastewater treatment. By combining the self-cleaning mechanism and the stirring mechanism, this invention solves the problem in existing self-cleaning multi-layer filtration structures for laboratory wastewater treatment where activated carbon is prone to caking, resulting in a reduction in the effective adsorption area.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a self-cleaning multi-layer filtration structure for laboratory wastewater treatment, comprising a filter box, a filter screen inside the filter box, activated carbon at the bottom of the filter box, a water inlet pipe connected to the top of the filter box, a drain plate fixedly connected to the bottom of the filter box, a self-cleaning mechanism inside the filter box, the self-cleaning mechanism including a power component on one side of the filter box, a cleaning component inside the filter box, and a collection component on one side of the filter box, and an agitation mechanism inside the filter box, the agitation mechanism including a base plate fixedly connected to the bottom of the filter box, a lifting component inside the filter box, and an agitation component inside the filter box.

[0008] The present invention is further configured such that a door is movably connected to the front side of the filter box via a hinge, a filter frame is fixedly connected inside the filter box, and the filter screen is fixedly connected inside the filter frame by bolts.

[0009] The present invention is further configured such that the power assembly includes a dual-shaft motor fixedly connected to the bottom of the filter box, a driving bevel gear fixedly connected to one output end of the dual-shaft motor, a driven bevel gear meshing with the driving bevel gear, a driving pulley fixedly connected to the other output end of the dual-shaft motor, and a driven pulley connected by belt drive.

[0010] The present invention is further configured such that the cleaning assembly includes a reciprocating lead screw movably connected to the inside of the filter box via a bearing, a reciprocating sleeve sleeved on the surface of the reciprocating lead screw, a cleaning brush fixedly connected to the bottom of the reciprocating sleeve, a support rod fixedly connected to the inside of the filter box, and a slider slidably connected to the surface of the support rod. The slider is fixedly connected to the cleaning brush. An electromagnetic clutch is fixedly connected to one side of the filter box, and the reciprocating lead screw is fixedly connected to the electromagnetic clutch.

[0011] The present invention is further configured such that the collection assembly includes an electric push rod fixedly connected to one side of the filter box, a closed plate fixedly connected to the output end of the electric push rod, and a collection box disposed on one side of the filter box, wherein a slag discharge channel is provided on the side of the filter box near the collection box.

[0012] The present invention is further configured such that the lifting assembly includes a lifting box fixedly connected inside the filter box, and an auger disposed inside the lifting box.

[0013] The present invention is further configured such that the agitation assembly includes an extension rod disposed on the top of the base plate and an agitation plate fixedly connected to the top of the extension rod.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model effectively solves the problem of activated carbon layer caking by setting up a stirring mechanism. The dual-shaft motor transmits power to the auger in the lifting assembly through a pair of bevel gears, causing it to rotate continuously in the lifting box. The rotating auger lifts the activated carbon at the bottom upwards and throws it from the top. At the same time, the stirring plate fixed to the bottom of the auger rotates accordingly, continuously pushing the scattered activated carbon around it towards the bottom inlet of the lifting box. This forms a continuous internal circulation of lifting, scattering, and reflux within the activated carbon layer, effectively breaking the static accumulation of activated carbon particles, keeping them in a loose state, allowing wastewater to fully contact the activated carbon, and effectively extending its effective adsorption life.

[0016] 2. This utility model achieves automatic cleaning and collection of impurities on the filter screen surface through a self-cleaning mechanism, effectively preventing filter pore blockage. When cleaning is required, the dual-axis motor in the power assembly starts, and its power is transmitted to the electromagnetic clutch through the active and driven pulleys, thereby driving the reciprocating screw to rotate. The reciprocating screw drives the reciprocating sleeve on it and the cleaning brush at the bottom to perform linear reciprocating motion, continuously scraping the impurities trapped on the filter screen to one side. At the same time, the electric push rod in the collection assembly moves, pulling open the sealing plate to open the slag discharge channel. The impurities pushed to the opening of the channel finally fall into the detachable collection box. The automated scraping and collection linkage process replaces the traditional manual cleaning, which not only ensures the continuous and stable operation of the filtration process, but also effectively improves the processing efficiency.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1 Please see Figures 1-5 This utility model is a self-cleaning multi-layer filtration structure for laboratory wastewater treatment, including a filter box 1, a filter screen 2 inside the filter box 1, activated carbon 3 at the bottom of the filter box 1, a water inlet pipe 4 connected to the top of the filter box 1, a drain plate 5 fixedly connected to the bottom of the filter box 1, a self-cleaning mechanism 6 inside the filter box 1, the self-cleaning mechanism 6 including a power component 61 on one side of the filter box 1, a cleaning component 62 inside the filter box 1, and a collection component 63 on one side of the filter box 1, and an agitation mechanism 7 inside the filter box 1, the agitation mechanism 7 including a base plate 71 fixedly connected to the bottom of the filter box 1, a lifting component 72 inside the filter box 1, and an agitation component 73 inside the filter box 1.

[0027] As a preferred embodiment of the above, the self-cleaning mechanism 6 automatically removes solid impurities accumulated on the surface of the filter screen 2, preventing mesh blockage and maintaining stable filtration efficiency. The dual-shaft motor 611 in the power assembly 61 starts, transmitting power to the electromagnetic clutch 9 via the driving pulley 614 and driven pulley 615. When cleaning is required, the electromagnetic clutch 9 engages, transmitting power to the reciprocating screw 621 to rotate it. The reciprocating sleeve 622 on the reciprocating screw 621 then performs linear reciprocating motion, driving the cleaning brush 623 at its bottom to move as well. During this movement, the bottom of the cleaning brush 623 directly scrapes the surface of the filter screen 2, pushing the trapped impurities to one side. Simultaneously, the electric push rod 631 in the collection assembly 63 actuates, pulling the sealing plate 632 to open the slag discharge channel. Impurities pushed to the opening of the channel fall into the detachable collection box 633, completing the automatic collection of impurities. The function of the agitation mechanism 7 is to prevent the activated carbon 3 layer at the bottom of the filter box 1 from caking. By keeping it in a loose state through continuous flow, it prolongs the adsorption and filtration effect. The other output end of the dual-shaft motor 611 drives the active bevel gear 612, which in turn drives the driven bevel gear 613 to rotate. The driven bevel gear 613 directly drives the auger 722 to rotate inside the lifting box 721. The rotating auger 722 continuously lifts the activated carbon 3 at the bottom upwards. The activated carbon 3 at the top falls to the surroundings under the action of gravity. At the same time, the extension rod 731, which is fixedly connected to the bottom of the auger 722, drives the agitation plate 732 at the top to rotate. The agitation plate 732 continuously pushes the activated carbon 3 scattered on the bottom plate 71 towards the bottom inlet of the lifting box 721, thus forming a continuous and cyclical agitation and lifting process in the filter box 1, effectively preventing the activated carbon 3 from caking.

The power assembly 61 includes a dual-axis motor 611 fixedly connected to the bottom of the filter box 1, a driving bevel gear 612 fixedly connected to one output end of the dual-axis motor 611, a driven bevel gear 613 meshing with the driving bevel gear 612, and a driving pulley 6 fixedly connected to the other output end of the dual-axis motor 611. 14, and a driven pulley 615 connected by a belt drive, the driven pulley 615 being fixedly connected to the electromagnetic clutch 9; the cleaning assembly 62 includes a reciprocating screw 621 movably connected to the inside of the filter box 1 via a bearing, a reciprocating sleeve 622 sleeved on the surface of the reciprocating screw 621, a cleaning brush 623 fixedly connected to the bottom of the reciprocating sleeve 622, the bottom of the cleaning brush 623 contacting the top of the filter screen 2, a support rod 624 fixedly connected to the inside of the filter box 1, and a slidably connected to the surface of the support rod 624. The filter box 1 has a slider 625, which is fixedly connected to the cleaning brush 623. An electromagnetic clutch 9 is fixedly connected to one side of the filter box 1, and a reciprocating screw 621 is fixedly connected to the electromagnetic clutch 9. The collection assembly 63 includes an electric push rod 631 fixedly connected to one side of the filter box 1, a closed plate 632 fixedly connected to the output end of the electric push rod 631, and a collection box 633 located on one side of the filter box 1. The collection box 633 is detachable, and a slag discharge passage is provided on the side of the filter box 1 near the collection box 633. The trough and lifting assembly 72 include a lifting box 721 fixedly connected inside the filter box 1, and an auger 722 disposed inside the lifting box 721. The bottom of the auger 722 is movably connected to the base plate 71 via a bearing. The bottom of the auger 722 extends to the bottom of the filter box 1 and is fixedly connected to the driven bevel gear 613. The agitation assembly 73 includes an extension rod 731 disposed on the top of the base plate 71, and an agitation plate 732 fixedly connected to the top of the extension rod 731. The extension rod 731 is fixedly connected to the auger 722.

[0029] As a preferred embodiment of the above: the filter frame 8 is used to fix the filter screen 2 inside the filter frame 8; the power assembly 61 provides power to the auger 722 through the driving bevel gear 612 and driven bevel gear 613, and provides power to the reciprocating screw 621 through the driving pulley 614 and driven pulley 615; the cleaning assembly 62 drives the reciprocating sleeve 622 and cleaning brush 623 to continuously reciprocate on the surface of the filter screen 2, pushing the impurities filtered out by the filter screen 2 towards the collection box 633, and through electromagnetic... The clutch 9 is configured such that when the filter screen 2 needs self-cleaning, the electromagnetic clutch 9 is energized to transmit the power of the dual-shaft motor 611 to the reciprocating screw 621. The collection component 63 collects the impurities pushed out by the cleaning brush 623. The lifting component 72 continuously lifts the activated carbon 3 at the bottom of the filter box 1. Together with the stirring component 73, the activated carbon 3 forms an upward circulation, preventing the activated carbon 3 from caking and reducing the filtration effect. The stirring component 73 pushes the activated carbon 3 at the top of the bottom plate 71 toward the lifting box 721.

[0030] The working principle of this utility model is as follows: When filtration is required, wastewater enters the filter box 1 through the inlet pipe 4. First, it passes through the filter screen 2, where solid impurities on the surface are intercepted. Then, the wastewater flows downward through the activated carbon 3 layer, where dissolved pollutants are adsorbed. During this process, the dual-shaft motor 611 operates continuously. Its output end drives the auger 722 to rotate inside the lifting box 721 through the meshing of the active bevel gear 612 and the driven bevel gear 613. The rotating auger 722 continuously lifts the activated carbon 3 at the bottom upward, causing it to fall from the top. At the same time, the stirring plate 732, which rotates synchronously with the auger 722, pushes the activated carbon 3 at the bottom towards the inlet of the lifting box 721, thereby forming an internal circulation in the filter box 1, effectively preventing the activated carbon 3 from caking and maintaining its adsorption activity.

[0031] When the filter screen 2 needs cleaning, the electromagnetic clutch 9 is energized and engages, transmitting the power from the other output end of the dual-shaft motor 611 to the reciprocating screw 621 via the driving pulley 614 and the driven pulley 615. The rotation of the reciprocating screw 621 drives the reciprocating sleeve 622 and the cleaning brush 623 fixed thereon to move back and forth in a straight line, scraping the impurities on the surface of the filter screen 2 to one side. At the same time, the electric push rod 631 is activated, pulling the sealing plate 632 to open the slag discharge channel. The impurities pushed to the opening of the channel by the cleaning brush 623 fall into the detachable collection box 633 under the action of subsequent thrust and gravity, completing the automatic slag cleaning and collection.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
