Description

Technical Field

[0001] This utility model relates to the field of sewage pumping station technology, specifically to an anti-tangling and pulverizing type bar. Background Technology

[0002] A shredder bar is a sludge removal and shredding device used in pump station systems. It generally consists of a drive unit, a shredding unit, and a bar screen. The shredding unit is used to shred floating garbage in the sewage, while the bar screen is used to block large particles of garbage. The bar screen is also called a rotating drum, which contains a continuously rotating rake that pushes the garbage to the shredding unit. In other words, the rotating drum is constantly rotating to push the garbage to the shredding unit.

[0003] When the drum rotates without effective anti-entanglement cutting, it may affect the working efficiency of the shredder. This is because existing drums have gaps and lack anti-entanglement devices, so waste in the sewage can easily get entangled in the gaps of the drum during rotation. Over time, the waste will accumulate, leading to a decrease in the drum's oscillation effect and affecting the working efficiency of the shredder. Therefore, an anti-entanglement shredder is proposed to solve the above-mentioned technical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-winding shredder, which has advantages such as good anti-winding effect. It solves the problem that existing rotating drums have gaps and no anti-winding facilities, so during rotation, garbage in sewage easily gets tangled in the gaps of the rotating drum. After long-term use, the garbage will become more and more tangled, resulting in poor drum fluctuation effect and affecting the working efficiency of the shredder.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-tangling pulverizing grid, comprising a grid shell, two rotating drums, and an anti-tangling component;

[0006] Both of the aforementioned drums are rotatably disposed inside the grid housing to push the waste to the crushing section. The anti-tangling component is disposed inside the grid housing and located on the opposite side of the two drums to cut and clean the waste tangled on the outside of the drums.

[0007] The anti-tangling component includes two mounting plates, which are respectively disposed inside the grid housing and located on opposite sides of the two rotating drums. Each of the two mounting plates has several grooves on its opposite side. The inner walls of the grooves are horizontally provided with support springs, and a cutter is provided on the side of the support springs away from the inner walls of the grooves to cut the garbage tangled on the outside of the rotating drums.

[0008] Furthermore, a crushing shaft is vertically arranged inside the grid housing and between the two opposing sides of the rotating drum, so that the waste is crushed by the crushing shaft when the rotating drum moves the waste.

[0009] Furthermore, both mounting plates have arc-shaped cross-sections, and several grooves are arranged in a rectangular array on opposite sides of the two mounting plates.

[0010] Furthermore, the cutter has a triangular cross-sectional shape, and the width of the cutter is equal to the distance between the upper and lower inner walls of the groove, so as to expand the tearing range after cutting the tangled garbage.

[0011] Furthermore, a baffle is provided on the inner peripheral wall of the mounting plate and on the rear side of the groove to provide back support for the cutter and prevent the cutter head from tilting up.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This anti-tangling shredder features a drum design that not only agitates debris but also works in conjunction with a cutter to automate waste removal, reducing the risk of the drum becoming entangled. The cutter's triangular cross-section and width, matched to the distance from the inner wall of the groove, allow it to effectively cut tangled debris and retract into the groove when not in use, protecting both the drum and the cutter. The use of support springs provides the cutter with the necessary elasticity, enabling it to apply appropriate pressure when cutting tangled debris and provide restoring force when avoiding it. The arc-shaped cross-section of the mounting plate and the rectangular array distribution of the grooves increase the coverage of the anti-tangling components and improve cutting efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figures 1 to 5 The anti-tangling and pulverizing grid in this embodiment includes a grid shell 1, two rotating drums 2 and an anti-tangling component 3.

[0022] Both rotating drums 2 are rotatably disposed inside the grid housing 1 to push the waste to the crushing section. The anti-tangling component 3 is disposed inside the grid housing 1 and located on the opposite side of the two rotating drums 2 to cut and clean the waste tangled on the outside of the rotating drums 2.

[0023] Example 2: Please refer to Figures 2 to 5 Based on Embodiment 1, the anti-tangling component 3 in this embodiment includes two mounting plates 31. The two mounting plates 31 are respectively disposed inside the grid housing 1 and located on opposite sides of the two rotating drums 2. Each of the two mounting plates 31 has several grooves 32 on its opposite side. The inner walls of the grooves 32 are horizontally provided with support springs 33, and the side of the support springs 33 away from the inner walls of the grooves 32 is provided with a cutter 34 for cutting the garbage tangled on the outside of the rotating drums 2. When the cutter 34 contacts the connection of the rotating drums 2, it can compress the support springs 33 and retract into the grooves 32 to avoid them, ensuring that the rotating drums 2 can rotate normally without being stuck or damaged by the cutter 34. The support springs 33 not only push the cutter 34 to cut, but also provide a restoring force after the cutter 34 avoids them, so that the cutter 34 returns to its initial position and is ready for the next cut.

[0024] In this embodiment, a crushing shaft 4 is vertically arranged inside the grid housing 1 and between the two opposing sides of the rotating drums 2. The crushing shaft 4 crushes the garbage when the rotating drums 2 move the garbage. The other side of the rotating drums 2 contacts the cutter 34 on the inner side of the mounting plate 31. The cutter 34 is inserted into the gap on the rotating drums 2 under the push of the support spring 33. As the rotating drums 2 rotate, the cutter 34 cuts the garbage wrapped around the rotating drums 2, effectively removing the entangled material and keeping the rotating drums 2 clean and operating efficiently.

[0025] In this embodiment, the cross-sectional shape of both mounting plates 31 is arc-shaped, and a number of grooves 32 are arranged in a rectangular array on one side of the two mounting plates 31. The cross-sectional shape of the cutter 34 is triangular, and the width of the cutter 34 is equal to the distance between the upper and lower inner walls of the groove 32, so as to expand the tearing range after cutting the entangled garbage. A baffle 35 is provided on the inner peripheral wall of the mounting plate 31 and on the rear side of the groove 32 to provide back support for the cutter 34 and prevent the head of the cutter 34 from lifting up.

[0026] It should be noted that the rotating drum 2 performs two main functions when rotating: one side pushes the garbage towards the crushing shaft 4, and the other side contacts the cutter 34 inside the mounting plate 31. When the garbage is pushed towards the crushing shaft 4 by the rotating drum 2, the crushing shaft 4 crushes the garbage into small particles to prevent subsequent equipment from being blocked.

[0027] The working principle of the above embodiments is as follows:

[0028] The rotating drum 2 performs two main functions during rotation: one side pushes the waste towards the crushing shaft 4, and the other side contacts the cutter 34 inside the mounting plate 31. When the waste is pushed towards the crushing shaft 4 by the rotating drum 2, the crushing shaft 4 crushes the waste into small particles to prevent subsequent equipment from being blocked. The other side of the rotating drum 2 contacts the cutter 34 inside the mounting plate 31. The cutter 34 is inserted into the gap on the rotating drum 2 under the push of the support spring 33. As the rotating drum 2 rotates, the cutter 34 cuts the waste wrapped around the rotating drum 2, effectively removing the entanglement and keeping the rotating drum 2 clean and operating efficiently. When the cutter 34 contacts the connection of the rotating drum 2, it can compress the support spring 33 and retract into the groove 32 to avoid it, ensuring that the rotating drum 2 can rotate normally without being stuck or damaged by the cutter 34. The support spring 33 not only pushes the cutter 34 to cut, but also provides a restoring force after the cutter 34 avoids it, so that the cutter 34 returns to its initial position, ready for the next cut.
