Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a garbage interception device for wastewater treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the standards for discharge into a water body or for reuse. Wastewater mainly includes domestic sewage, industrial wastewater, and initial rainwater runoff. In the early stages of wastewater treatment, appropriate interception devices are usually used to intercept and treat impurities mixed in the wastewater.

[0003] In existing technologies, such as the Chinese patent with publication number CN218357628U, a waste interception device for centralized domestic sewage treatment is described. In its initial state, a support plate receives and intercepts the waste, causing it to remain on the plate. When the intercepted waste needs to be cleared, a telescopic device moves the support plate upwards, and finally, a pushing component pushes the waste off the support plate, thus assisting manual removal. However, in this waste interception device, the support plate is connected to the baffles via square collars. When the support plate moves upwards, waste attached to the baffles may become stuck between two adjacent square collars and cannot be cleared. Therefore, the waste clearing efficiency of this centralized domestic sewage treatment waste interception device is low. Utility Model Content

[0014] The mounting plate is fixed to the upper edge of the frame.

[0015] Preferably, the bottom of the frame is provided with lower support plates on the left and right sides respectively;

[0016] The mounting plate is provided with upper support plates on both the left and right sides.

[0017] Preferably, the side plate has a lifting hole, and the lifting hole has a rack on the hole wall away from the frame.

[0018] Preferably, the slag removal mechanism includes a rotating shaft and a plurality of slag removal blades, the plurality of slag removal blades being fixed to the circumferential side of the rotating shaft.

[0019] Preferably, the left and right ends of the rotating shaft are respectively provided with driving gears, which are disposed in the lifting hole and mesh with the rack.

[0020] Preferably, the slag-cleaning plate extends between two adjacent slag-blocking plates, and the left and right sides of the slag-cleaning plate abut against the opposite surfaces of the two adjacent slag-blocking plates, respectively.

[0021] Preferably, the slag-cleaning plate is an arc-shaped plate, and when the slag-cleaning plate enters between the two slag-blocking plates and the radial line of the connection point between the slag-cleaning plate and the rotating shaft is horizontal, the slag-cleaning plate bends downward relative to the horizontal surface.

[0022] Preferably, the left and right sides of the slag hopper are respectively provided with connecting plates, and the driving gear is rotatably connected to the connecting plates;

[0023] The outer side of the connecting plate is provided with a connecting block.

[0024] Preferably, the lifting mechanism includes a first bevel gear, a second bevel gear, a lead screw, and a forward and reverse motor, wherein there are two of each of the first bevel gear, the second bevel gear, and the lead screw;

At the same time, the gear rotates under the meshing action with the rack, and the rotating shaft also rotates. The slag cleaning plate rotates clockwise with the rotating shaft. After the slag cleaning plate enters between two adjacent slag baffles, the slag cleaning plate comes into contact with the garbage attached to the slag baffles. At this time, the garbage will be pushed towards the slag hopper and upward. The garbage is scraped up and pushed into the slag hopper. As the slag hopper rises, the garbage will fall into the slag hopper. In this way, the garbage attached to the slag baffles can be cleaned efficiently.

[0030] 2. Because the slag hopper and the slag cleaning plate are in contact, the slag hopper can assist the slag removal mechanism in scraping away the garbage on the slag baffle plate.

[0031] 3. The gear and rack work together to make the shaft rotate during the upward movement. In this way, multiple cleaning blades on the side of the shaft can continuously enter between two adjacent slag baffles as it rotates, and provide a pushing force to the garbage, pushing the garbage towards the slag hopper.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0039] This utility model proposes a garbage interception device for sewage treatment, such as... Figure 1 and Figure 2 As shown, the device includes a slag hopper 1 and a slag-blocking frame 2. The slag-blocking frame 2 is equipped with multiple vertical slag-blocking plates 211. The slag hopper 1 slides vertically on the inlet side of the slag-blocking frame 2, and the slag hopper 1 abuts against the multiple slag-blocking plates 211. The slag-blocking frame 2 is equipped with a lifting mechanism that can drive the slag hopper 1 to rise and fall. It also includes a slag-removing mechanism 100 that can move the garbage attached to the surface of the slag-blocking plates 211. The slag-removing mechanism 100 is located on the outlet side of the slag-blocking frame 2 and is connected to the slag hopper 1.

[0040] like Figure 1 and Figure 4 As shown, the slag hopper 1 is a U-shaped hopper, and the bottom of the inlet of the slag hopper 1 is provided with a slag inlet slope 11.

[0041] The slag inlet ramp 11 allows the waste to enter the slag hopper 1 more smoothly.

[0042] like Figure 3 As shown, the slag-blocking frame 2 also includes a frame 21, side plates 22 and mounting plate 24. Multiple slag-blocking plates 211 are fixed inside the frame 21. The slag hopper 1 slides vertically on the water inlet side of the frame 21. There are two side plates 22, which are fixed on the left and right sides of the frame 21 respectively, and the two side plates 22 are set on the water outlet side of the frame 21. The mounting plate 24 is fixed on the upper edge of the frame 21.

[0043] like Figure 3 As shown, the bottom left and right sides of the frame 21 are respectively provided with lower support plates 25.

[0044] like Figure 3 As shown, the mounting plate 24 is provided with upper support plates 26 on the left and right sides respectively.

[0045] like Figure 3 and Figure 5As shown, a lifting hole 221 is provided on the side plate 22, and a rack 23 is provided on the hole wall of the lifting hole 221 away from the frame 21.

[0046] like Figure 4 As shown, the slag removal mechanism 100 includes a rotating shaft 101 and a plurality of slag removal plates 102, which are fixed to the circumferential side of the rotating shaft 101.

[0047] The slag removal plate 102 extends between two adjacent slag-blocking plates 211, and the left and right sides of the slag removal plate 102 abut against the opposite surfaces of the two adjacent slag-blocking plates 211 respectively.

[0048] like Figure 5 As shown, the slag removal plate 102 is an arc-shaped plate. When the slag removal plate 102 enters between the two slag blocking plates 211 and the radial line of the connection point between the slag removal plate 102 and the rotating shaft 101 is horizontal, the slag removal plate 102 bends downward relative to the horizontal surface.

[0049] like Figure 4 and Figure 5 As shown, the left and right ends of the rotating shaft 101 are respectively provided with driving gears 103, which are installed in the lifting hole 221 and mesh with the rack 23.

[0050] like Figure 4 As shown, the left and right sides of the slag hopper 1 are respectively provided with connecting plates 12, which drive the gear 103 to rotate and connect with the connecting plates 12.

[0051] When the lifting mechanism raises the slag hopper 1, it drives the gear 103 to move the rotating shaft 101 upwards. Simultaneously, the gear 103 rotates in mesh with the rack 23, and the rotating shaft 101 also rotates accordingly. Figure 5 As shown, the cleaning plate 102 rotates clockwise with the rotating shaft 101. After the cleaning plate 102 enters between two adjacent slag-blocking plates 211, the cleaning plate 102 comes into contact with the garbage attached to the slag-blocking plates 211. At this time, the garbage will be pushed towards the slag hopper 1 and upward. The garbage is scraped up and pushed towards the slag hopper 1. As the slag hopper 1 rises, the garbage will fall into the slag hopper 1. In this way, the garbage attached to the slag-blocking plates 211 can be cleaned efficiently.

[0052] Since the slag hopper 1 and the slag cleaning plate 102 are in contact, the slag hopper 1 can assist the slag removal mechanism 100 in scraping the garbage on the slag baffle plate 211.

[0053] The gear 103 engages with the rack 23, causing the shaft 101 to rotate during its ascent. This allows multiple cleaning plates 102 on the circumferential side of the shaft 101 to continuously enter between two adjacent slag-blocking plates 211 as the shaft rotates, providing a pushing force to the waste and pushing it toward the slag hopper 1.

[0054] like Figure 4As shown, a connecting block 13 is provided on the outer side of the connecting plate 12.

[0055] like Figure 1 and Figure 2 As shown, the lifting mechanism includes a first bevel gear 6, a second bevel gear 7, a lead screw 8, and a forward and reverse motor 3. There are two of each of the first bevel gear 6, the second bevel gear 7, and the lead screw 8.

[0056] The lead screw 8 rotates between the lower support plate 25 and the upper support plate 26. The upper end of the lead screw 8 passes through the upper support plate 26, and the lead screw 8 is threadedly connected to the connecting block 13.

[0057] The second bevel gear 7 is fixed to the upper end of the lead screw 8, and the two first bevel gears 6 are connected by the transmission shaft 5. The transmission shaft 5 rotates on the upper surface of the mounting plate 24, and the first bevel gear 6 meshes with the second bevel gear 7.

[0058] The forward and reverse motor 3 is mounted on the upper surface of the mounting plate 24. The output end of the forward and reverse motor 3 is fixed with a drive gear 4, and the shaft of the transmission shaft 5 is fixed with a driven gear 9. The drive gear 4 and the driven gear 9 mesh.

[0059] Using this invention, when it is necessary to clean up the garbage accumulated at the bottom of the slag-blocking frame 2 and attached to the surface of the slag-blocking plate 211, the forward and reverse motor 3 is started first. The forward and reverse motor 3 drives the drive gear 4 to rotate, the drive gear 4 drives the driven gear 9 to rotate, the driven gear 9 drives the transmission shaft 5 to rotate, and the bevel gears 6 at both ends of the transmission shaft 5 also rotate accordingly. The two bevel gears 6 drive the two bevel gears 7 to rotate respectively, and the bevel gears 7 drive the corresponding lead screws 8 to rotate. The connecting block 13 moves upward accordingly, and drives the slag hopper 1 to move upward through the connecting plate 12. The connecting plate 12 simultaneously drives the slag-removing mechanism 1. As the slag-removing mechanism 100 moves upward, it drives the gear 103 to rotate under the meshing action with the rack 23. The rotating shaft 101 also rotates accordingly, and the slag-removing plate 102 also rotates with the rotating shaft 101. Since the slag-removing plate 102 is an arc-shaped plate, after the slag-removing plate 102 comes into contact with the garbage attached to the slag-blocking plate 211, the garbage will be pushed towards the slag hopper 1 by a pushing force, which will scrape up the garbage and push it towards the slag hopper 1. After the garbage separates from the slag-blocking plate 211, it falls into the slag hopper 1. After the slag hopper 1 rises to the upper part of the slag-blocking frame 2, the staff cleans the garbage in the slag hopper 1 and finally lowers the slag hopper 1.

[0060] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
