Description

An arch-breaking structure for a sludge treatment device Technical Field

[0001] This utility model relates to the technical field of sludge treatment equipment, specifically to an arch-breaking structure for a sludge treatment device. Background Technology

[0002] The arch-breaking structure is mainly used at the bottom of the silo. Its reciprocating motion breaks up the arch structure formed by the material, allowing it to fall smoothly to the silo outlet. As shown in Figure 1, in some technologies, because the silo outlet is located on one side of the slide frame, sludge on the other side cannot enter the silo outlet from the other side of the slide frame due to the obstruction of the slide frame. This results in sludge accumulation in that area, affecting the efficiency of equipment operation and increasing the difficulty and cost of later maintenance. Summary of the Invention

[0003] To address the aforementioned issues, this application provides an arch-breaking structure for a sludge treatment device, which can prevent sludge from accumulating at the bottom of the silo, thereby achieving a better cleaning effect.

[0004] The purpose of this utility model is achieved through the following technical solution: a sludge treatment device with an arch-breaking structure, which is set in a silo, and includes an arch-breaking slide that can reciprocate back and forth in the silo and a rocker arm connected to the arch-breaking slide.

[0005] The arch-breaking slide includes a slide assembly and a slide keel connected to the slide assembly. The rocker arm is connected to the slide keel. When the arch-breaking slide reciprocates, it can drive the rocker arm to swing, so as to push the material on the side of the slide keel away from the discharge port of the hopper toward the discharge port.

[0006] This invention uses a swingable rocker arm to push the material on the side of the carriage keel away from the discharge port toward the discharge port, preventing the material from accumulating in that area, making the discharge more thorough, and reducing the difficulty and cost of equipment maintenance.

[0007] One end of the rocker arm is provided with a fixing hole, and a fixing post is provided on the carriage keel that is inserted into the fixing hole. The fixing post and the fixing hole are fitted with a clearance so that the rocker arm can swing with the fixing post as the fulcrum.

[0008] The lower surface of the rocker arm is provided with a sliding groove extending along its axial direction, and a limiting block that engages with the sliding groove is fixedly provided at the bottom of the hopper; when the rocker arm swings, the limiting block moves relative to the sliding groove.

[0009] The combination of the chute and the limit block allows the rocker arm to swing back and forth along the set path, better pushing the material towards the discharge port.

[0010] The slide has a side hole communicating with at least one end, and the side hole extends to the outside of the rocker arm.

[0011] The side hole allows the material entering the chute to be squeezed out through the side hole when the limit block moves relative to the chute, thus preventing too much material from entering the chute and affecting the normal swing of the rocker arm.

[0012] The rocker arm is provided with a blocking mechanism for blocking the side hole from the outside; the blocking mechanism includes two mounting blocks arranged opposite each other, a rotating shaft connecting the two mounting blocks, and a baffle connected to the rotating shaft for blocking the side hole from the outside; the size of the baffle is larger than the size of the side hole.

[0013] This invention uses a shielding mechanism to prevent material from entering the chute from the side hole when the rocker arm swings.

[0014] The carriage assembly includes a front push rod and a rear push rod spaced apart, and two reinforcing rods are connected to the two ends of the front push rod and the rear push rod respectively; the carriage keel connects the front push rod and the rear push rod.

[0015] The arch-breaking structure of the sludge treatment device also includes a central push rod, which is connected between the carriage keel and the reinforcing rod near the discharge port.

[0016] This invention improves the material pushing effect by setting multiple push rods.

[0017] The arch-breaking structure of the sludge treatment device also includes a carriage handle connected to the carriage assembly, which extends outside the hopper.

[0018] Compared with the prior art, this application has the following beneficial effects: the present invention uses a swingable rocker arm to push the material on the side of the carriage keel away from the discharge port toward the discharge port, preventing the material from accumulating in this area, making the discharge more thorough, and reducing the maintenance difficulty and cost of the equipment.

Detailed Implementation

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

[0035] Example 1

[0036] As shown in Figure 2, this embodiment discloses an arch-breaking structure for a sludge treatment device, which is installed at the bottom of the silo 100 of the sludge treatment device. The arch-breaking structure includes an arch-breaking slide 200 capable of reciprocating back and forth within the silo 100 along a predetermined path, and a rocker arm 300 connected to the arch-breaking slide 200. Specifically, the width of the arch-breaking structure matches the width of the bottom of the silo 100, so that the arch-breaking structure is limited in the width direction and can only reciprocate in the front-back direction.

[0037] Specifically, as shown in Figure 6, the arch-breaking slide 200 includes a slide assembly and a slide frame 210 connected to the slide assembly. The slide assembly includes a front push rod 240 and a rear push rod 250 spaced apart, and two reinforcing rods 260 connected to the two ends of the front push rod 240 and the rear push rod 250, respectively; the slide frame 210 connects the front push rod 240 and the rear push rod 250. Through the above structure, the front push rod 240, the rear push rod 250, and the two reinforcing rods 260 together form a rectangular frame. When the arch-breaking structure moves back and forth, the front push rod 240 and the rear push rod 250 repeatedly push the sludge, preventing the sludge from forming an arch bridge structure at the discharge port 110 of the silo 100 and affecting the sludge discharge from the silo 100; at the same time, the front push rod 240 and the rear push rod 250 can also repeatedly push the sludge towards the discharge port 110, improving the sludge discharge efficiency.

[0038] Of course, the two reinforcing rods 260 can also be connected to the front push rod 240 and the rear push rod 250 near the middle. The reinforcing rods 260 can be vertically or obliquely positioned relative to the front push rod 240 and the rear push rod 250. Alternatively, the number of reinforcing rods 260 can be one or more, as long as they can reinforce the front push rod 240 and the rear push rod 250.

[0039] As one implementation, the arch-breaking structure also includes a central push rod 230, which connects the carriage keel 210 and the reinforcing rod 260 near the discharge port 110, as shown in Figures 2 and 6. Using multiple push rods can improve the material pushing effect of the arch-breaking structure.

[0040] In addition, a slide handle 270 is connected to the slide assembly, which extends outside the hopper 100 to facilitate the reciprocating push of the arch-breaking structure from the outside of the hopper 100. In use, the arch-breaking structure can be manually pushed back and forth, or a pushing device, such as a cylinder or hydraulic rod, can be installed on the outside of the hopper 100 to reciprocate the arch-breaking structure.

[0041] Specifically, the rocker arm 300 is oscillatingly connected to the slide frame 210. When the arch-breaking slide frame 200 reciprocates, it drives the rocker arm 300 to oscillate. The oscillation of the rocker arm 300 pushes the sludge on the side of the slide frame 210 away from the discharge port 110 toward the discharge port 110, preventing sludge from accumulating in that area, making the discharge more thorough, and reducing the difficulty and cost of equipment maintenance.

[0042] As shown in Figures 5, 8, and 9, one end of the rocker arm 300 is provided with a fixing hole 320. A fixing post 220, which is inserted into the fixing hole 320, is provided on the carriage frame 210. The fixing post 220 and the fixing hole 320 are fitted with a clearance, allowing the rocker arm 300 to swing around the fixing post 220 as a fulcrum. In this configuration, an opening 211 can be provided on the lower surface of the carriage frame 210. The fixing post 220 is located at the top of the opening 211 and extends downwards, as shown in Figure 9. The end of the rocker arm 300 is the connecting end, and the fixing hole 320 is located on the connecting end. The height of the opening 211 matches the thickness of the connecting end of the rocker arm 300. Therefore, when the end of the rocker arm 300 is installed in the opening 211, i.e., when the fixing post 220 is inserted into the fixing hole 320, the lower surface of the rocker arm 300 is flush with the lower surface of the carriage frame 210. The thickness of the rocker arm 300, excluding the connecting end, is greater than the thickness of the carriage keel 210. This makes it easier to push the sludge up and allow it to roll over the carriage keel 210. Additionally, the width of the opening 211 needs to be much greater than the width of the rocker arm 300 so that the side walls of the opening do not affect the normal swinging of the rocker arm 300; alternatively, the sides of the opening 210 can be angled to resemble a trumpet shape, which also prevents the side walls of the opening from affecting the normal swinging of the rocker arm 300.

[0043] Additionally, as shown in Figures 5, 7, and 8, the lower surface of the rocker arm 300 is provided with a groove 310 extending along its axial direction, and a limiting block 120 is fixedly provided at the bottom of the hopper 100, which engages with the groove 310. When the rocker arm 300 swings, the limiting block 120 moves relative to the groove 310. The cooperation between the groove 310 and the limiting block 120 allows the rocker arm 300 to swing back and forth along a set path, better pushing the material towards the discharge port 110.

[0044] With the above structure, when the arch-breaking structure moves forward, the rocker arm 300 swings backward under the guidance of the limiting block 120 and the slide 310, as shown in Figure 3. When the arch-breaking structure moves backward, the rocker arm 300 swings forward, as shown in Figure 4. The forward swing of the rocker arm 300, combined with the backward movement of the front push rod 240, pushes up and gathers the sludge on the side of the slide frame 210 away from the discharge port 110, causing the sludge to roll over the slide frame 210 and enter the side of the slide frame 210 closer to the discharge port 110. In the subsequent reciprocating movement, the arch-breaking structure better pushes the sludge towards the discharge port 110.

[0045] In this embodiment, the sludge on the side of the slide frame 210 away from the discharge port 110 is pushed towards the discharge port by the swingable rocker arm 300, which prevents the sludge from accumulating in this area, making the discharge more thorough and reducing the maintenance difficulty and cost of the equipment.

[0046] Example 2

[0047] The arch-breaking structure in this embodiment is based on that in embodiment 1, with at least one end of the slide groove 310 having a side hole 330 communicating with it, the side hole 330 extending to the outside of the rocker arm 300. In this embodiment, both ends of the slide groove 310 are provided with side holes 330, as shown in Figure 10.

[0048] During the reciprocating movement of the arch-breaking structure, sludge inevitably enters the chute 310 from below. If too much sludge enters the chute 310, it may affect the normal swing of the rocker arm. In this embodiment, the side hole 330 allows the limiting block 120 to squeeze the sludge that has entered the chute 310 out of the side hole 330 when it moves relative to the chute 310, thus preventing excessive sludge from entering the chute 310 and affecting the normal swing of the rocker arm 300.

[0049] Example 3

[0050] As shown in Figures 11 and 12, the arch-breaking structure in this embodiment, based on Embodiment 2, includes a blocking mechanism 340 on the rocker arm 300 for blocking the side hole 330 from the outside. Specifically, the blocking mechanism 340 includes two mounting blocks 341 arranged opposite each other, a rotating shaft 342 connecting the two mounting blocks 341, and a baffle 343 connected to the rotating shaft 342 for blocking the side hole 330 from the outside. The rotating shaft 342 is rotatable, and when the rotating shaft 342 rotates, the baffle 343 can flip, thereby opening or closing the side hole 330.

[0051] In addition, the size of the baffle 343 is larger than the size of the side hole 330, so the baffle 343 can only be flipped to the side away from the side hole, and cannot be flipped into the side hole.

[0052] With the above structure, when the limiting block 120 moves relative to the chute 310 and squeezes the sludge inside the chute 310, the squeezing force exerted by the sludge inside the chute 310 on the baffle 343 is greater than the resistance of the external sludge on the baffle 343. The sludge inside the chute 310 is squeezed open by the baffle 343 and discharged from the chute 310. Since the baffle 343 cannot swing inward to the side hole, the sludge cannot enter the chute 310 in reverse from the side hole 330 during the swinging process of the rocker arm 300 due to the obstruction of the baffle 343.

[0053] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0054] Furthermore, the specific embodiments described above are exemplary.
