Description

Technical Field

[0001] This utility model relates to the field of self-cleaning bar screen cleaners, specifically to a self-cleaning bar screen cleaner for sewage treatment. Background Technology

[0002] A bar screen is a specialized water treatment device that continuously and automatically intercepts and removes impurities from fluids using mechanical means. It is mainly used for solid-liquid separation, preventing blockages in subsequent treatment equipment, and ensuring the stable operation of the water treatment system. A self-cleaning bar screen used for sewage treatment is a specialized water treatment device that automatically removes intercepted impurities using its self-cleaning structure.

[0003] A search revealed a practical bar screen for wastewater treatment, with announcement number CN219652696U. Specifically relating to wastewater treatment, it includes a casing, a collection cart, a drive mechanism, a cleaning mechanism, and a cleaning brush. The collection cart is located at the bottom of the inner cavity of the casing, the drive mechanism is located on top of the collection cart, the cleaning mechanism is located on one side of the drive mechanism and the collection cart, and the cleaning brush is located at the bottom of the cleaning mechanism near the drive mechanism. This invention firstly, by activating the drive mechanism, the cleaning mechanism can remove suspended solids inside the wastewater treatment tank. Secondly, by activating the drive motor, the first transmission belt controls the rotation of the rotating rod and spiral blades, causing the wastewater inside the tank to carry the suspended solids towards the top filter plate of the fixed tank. This improves the cleaning efficiency of the cleaning mechanism for suspended solids in the wastewater. Simultaneously, the filter plate prevents suspended solids from entering the fixed tank and affecting the performance.

[0004] The bar screen cleaner used for sewage treatment in the aforementioned patent lacks a relevant cleaning structure. When filtering sewage, a large amount of impurities remain on the rake chain of the bar screen cleaning surface, which will affect the normal sewage cleaning effect. Cleaning requires manual shutdown of the machine, which not only delays work efficiency but also wastes a lot of time.

[0005] Therefore, it is necessary to invent a self-cleaning bar screen for sewage treatment to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a self-cleaning bar screen for sewage treatment. When the drive roller drives the entire rake chain to rotate, the first main synchronous pulley at one end of the drive roller drives the first synchronous belt and the first driven synchronous pulley to rotate. The rotation of the first driven synchronous pulley drives the reciprocating screw and the outer brush head to move back and forth outside the rake chain to clean the surface. When the first main synchronous pulley rotates, it drives the outer second main synchronous pulley. The second synchronous belt outside the second main synchronous pulley drives the second driven synchronous pulley and the inner roller sleeve and multiple rubber scrapers to clean the impurities in the gaps between the multiple rake chains, thereby enhancing the cleaning effect. This solves the problem in the aforementioned patent for sewage treatment in the background art that lacks a relevant cleaning structure. When filtering sewage, a large amount of impurities remain on the rake chain of the bar screen surface, which affects the normal sewage removal effect. Cleaning requires manual stopping of the machine, which not only delays work efficiency but also wastes a lot of time.

[0030] The first cleaning mechanism 9 is located inside the upper side of the frame 1. The first cleaning mechanism 9 includes a fixed frame 901, which is fixed inside the upper side of the frame 1. A reciprocating screw 902 is rotatably connected inside the fixed frame 901. A first driven synchronous pulley 903 is fixedly connected to one end of the reciprocating screw 902. A movable seat 905 is threadedly connected to the outside of the reciprocating screw 902. A connecting frame 906 is fixedly connected to the front side of the movable seat 905. A movable seat 909 is slidably connected inside the connecting frame 906. Brush heads 910 are provided on the surface of the movable seat 909.

[0031] The second cleaning mechanism 11 is located inside the frame 1 and below the first cleaning mechanism 9. The second cleaning mechanism 11 includes a transmission rod 1101, which is rotatably connected inside the frame 1. The other end of the transmission rod 1101 is fixedly connected to a second driven synchronous pulley 1102. A roller sleeve 1103 is fixedly connected to the outside of the transmission rod 1101. Rubber scrapers 1104 are fixedly installed on the outside of the roller sleeve 1103. When the transmission roller 3 drives the entire rake tooth chain 4 to rotate, the first main synchronous pulley 6 at one end of the transmission roller 3 drives... The first synchronous belt 8 and the first driven synchronous pulley 903 rotate, and the rotation of the first driven synchronous pulley 903 drives the reciprocating screw 902 and the outer brush head 910 to move back and forth outside the rake tooth chain 4 to clean the surface. When the first main synchronous pulley 6 rotates, it drives the outer second main synchronous pulley 7. The second synchronous belt 10 outside the second main synchronous pulley 7 drives the second driven synchronous pulley 1102 and the inner roller sleeve 1103 and multiple rubber scrapers 1104 to clean the impurities in the gaps between the multiple rake tooth chains 4, thereby enhancing the cleaning effect.

[0032] like Figure 1 and Figure 2 As shown, a protective shell 5 is threadedly connected to the other side of the frame 1, and the first main synchronous pulley 6 and the second main synchronous pulley 7 are located inside, which can protect the first main synchronous pulley 6, the second main synchronous pulley 7, the first slave synchronous pulley 903 and the second slave synchronous pulley 1102 from external dust or other objects, so as to prevent them from being damaged.

[0033] like Figure 2 and Figure 3 As shown, the other side of the first synchronous belt 8 is sleeved inside the first driven synchronous pulley 903. A slide rod 904 is fixedly connected inside the fixed frame 901. The movable seat 905 is sleeved outside the slide rod 904. When the first main synchronous pulley 6 rotates, it drives the external first synchronous belt 8 and the first driven synchronous pulley 903 to rotate. The rotation of the first driven synchronous pulley 903 drives the reciprocating screw 902 to rotate. The rotation of the reciprocating screw 902 drives the external movable seat 905 to move back and forth.

[0036] like Figure 3 and Figure 6 As shown, the other side of the second synchronous belt 10 is sleeved inside the second synchronous pulley 1102. The rubber scraper 1104 is located in the gap between the multiple sets of rake tooth chains 4. The transmission rod 1101 rotates to drive the outer roller sleeve 1103 and the rubber scraper 1104 to clean the impurities in the gap between the rake tooth chains 4.

[0037] The working principle of this practical device is as follows: First, the entire self-cleaning bar screen is installed inside the sewage treatment tank. Then, the drive motor 2 on the outside of the frame 1 is turned on, driving the transmission roller 3 to rotate. The rotation of the transmission roller 3 drives the external rake chain 4, which filters and removes the garbage from the sewage treatment tank. The garbage in the sewage is scooped out and left on the surface of the rake chain 4, and then driven to the upper part of the inside of the frame 1. When the rake chain 4 flips, the garbage on the surface falls off due to its own weight and is discharged. However, during the filtration process, a large amount of impurities inevitably remain on the surface of the rake chain 4, which affects the filtration effect. At this time, the rotation of the transmission roller 3 drives the first main synchronous pulley 6 at the other end, and the first main synchronous pulley 6 rotates and drives... The first synchronous belt 8 drives the first driven synchronous pulley 903. The rotation of the first driven synchronous pulley 903 drives the reciprocating screw 902 to rotate. When the reciprocating screw 902 rotates, it drives the moving seat 905 and the front moving seat 905 and brush head 910 to move back and forth on the surface of the rake tooth chain 4 for cleaning. At the same time, when the first main synchronous pulley 6 rotates, it drives the outer second main synchronous pulley 7. The second synchronous belt 10 outside the second main synchronous pulley 7 drives the second driven synchronous pulley 1102 and the inner roller sleeve 1103 and multiple rubber scrapers 1104 to clean the impurities in the gaps between the multiple rake tooth chains 4, thereby enhancing the cleaning effect. In this way, the use process of the self-cleaning bar screen cleaner for sewage treatment is completed.
