Automatic turning and throwing equipment for sludge composting

Abstract

This utility model provides an automatic turning and turning device for sludge composting, relating to the field of sludge composting technology. It includes a turning and turning device frame, with a turning and turning guide frame welded to the top of the frame. The turning and turning guide frame has a hollow structure, with both its top and bottom being arc-shaped. Sludge is cut and folded by a high-speed moving baffle and enters the turning and turning guide frame, impacting and crushing the clumps in the sludge, improving the breaking effect on the compacted layer of the compost pile. This device is suitable for treating hard sludge compost and solves the problems of traditional sludge composting methods, which typically involve manual turning or using a bucket truck to shovel and scatter the sludge before turning. These methods fail to effectively stir or break up the compost pile during turning, making it difficult to break up the compacted layer, resulting in poor aeration. Furthermore, the thorough mixing of sludge with straw, sawdust, and other auxiliary materials requires multiple turnings, leading to low turning efficiency in sludge composting.

Description

Technical Field

[0001] This utility model relates to the field of sludge composting technology, and in particular to an automatic turning and turning device for sludge composting. Background Technology

[0002] Sludge composting is a method of converting sludge into organic fertilizer. It has the advantages of being economical, simple, and environmentally friendly. It can reduce pollution and transform sludge, which is traditionally considered a pollutant, into a resource. When used in farmland, composting can increase organic matter, improve soil structure, and reduce potential soil erosion. The turning and tossing operation in the sludge composting process is the core link to ensure efficient and uniform decomposition. Turning and tossing breaks up the compacted layer of the pile and increases the porosity of the material, promotes oxygen penetration and uniform distribution, maintains the activity of aerobic microorganisms, and effectively solves the problem of oxygen deficiency caused by the blockage of aeration holes in traditional static composting.

[0003] Traditional sludge composting is typically done manually or by using a shovel to lift and spread the sludge. This process does not effectively mix or break up the compost, making it difficult to break up the compacted layer and resulting in poor aeration. Furthermore, thorough mixing of sludge with auxiliary materials such as straw and sawdust requires multiple turnings, leading to low efficiency in sludge composting. Utility Model Content

[0004] This utility model provides an automatic turning and turning device for sludge composting, which solves the problem that traditional sludge composting turning and turning work is generally carried out by manual turning or by using a bucket truck to shovel up the sludge compost and then scatter it for turning. During the turning and turning process, the compost cannot be effectively stirred or broken up, and it is difficult to break up the compacted layer of the pile, resulting in poor aeration effect of sludge compost. In addition, multiple turning and turning are required to fully mix sludge with auxiliary materials such as straw and sawdust, resulting in low turning and turning efficiency of sludge compost.

[0005] This utility model provides an automatic turning and composting device for sludge composting, specifically including: a turning and composting device frame, which is fixedly connected to a turning and composting guide frame; the turning and composting guide frame is an integrated hollow structure with an arc-shaped top and bottom, and a turning and composting drive mechanism is provided on its right side; an active rotating shaft and a driven rotating shaft are symmetrically distributed inside the turning and composting guide frame through bearings, wherein the active rotating shaft is connected to the turning and composting drive mechanism, and the driven rotating shaft is arranged parallel to the bottom of the active rotating shaft; a chain plate transmission assembly, including two chain plate active sprockets fixed to the active rotating shaft, two chain plate driven sprockets fixed to the driven rotating shaft, and a conveying chain plate meshing with the outer circumference of the sprockets; turning and composting plates are evenly distributed on the outer surface of the conveying chain plate; a sludge inlet and a discharge outlet are respectively opened at the bottom and top of the turning and composting guide frame.

[0006] Furthermore, the sludge inlet is located at the bottom front of the turning and throwing guide frame, and the throwing outlet is located at the top rear of the turning and throwing guide frame.

[0007] Furthermore, the turning plate located at the front of the turning guide frame is inclined upwards and forwards, with an angle of 70 degrees between the turning plate and the conveyor chain plate. The turning plate located behind the conveyor chain plate is inclined downwards and backwards.

[0008] Furthermore, the end of the conveyor chain plate is attached to the inner wall of the turning and throwing guide frame, and the outer edge of the turning and throwing plate is formed by bending.

[0009] Furthermore, the outer edge of the folded edge of the turning plate is in contact with the inner wall of the turning guide frame, and the end of the turning turning plate is in contact with the turning guide frame.

[0010] Furthermore, the active rotating shaft is coaxial with the top arc-shaped plate of the turning and throwing guide frame, and the driven rotating shaft is coaxial with the bottom arc-shaped plate of the turning and throwing guide frame.

[0011] This utility model provides an automatic turning and composting device for sludge composting, which has the following beneficial effects:

[0012] The turning and composting device of this utility model is specifically designed for turning and composting sludge. The device is moved by a cart frame over a stockpiled sludge compost. As the turning and composting guide frame moves forward, the sludge compost enters through the sludge inlet. Simultaneously, the conveyor chain rotates at high speed under the drive of the turning and composting drive unit, causing the turning and composting plate to flip upwards and forwards from the bottom of the sludge inlet. This scoops up the sludge compost entering the turning and composting guide frame and moves upwards with the continuous operation of the conveyor chain. When it reaches the discharge port, the turning and composting plate changes its trajectory under the drive of the conveyor chain and flips downwards. The sludge above the turning and composting plate is thrown backwards through the discharge port due to inertia, thus achieving the turning and composting of the sludge compost. The sludge is lifted and then thrown backwards, increasing the distance the sludge travels during its descent, increasing the contact time between the sludge and air, and improving the aeration effect.

[0013] Furthermore, as the height of the sludge turning increases, the mixing effect after turning is better, allowing the sludge to be more fully mixed with auxiliary materials such as straw and sawdust during the turning process. As the turning guide frame moves forward, the sludge is cut by the high-speed moving baffle and enters the interior of the turning guide frame, impacting and crushing the clump structure in the sludge, improving the breaking effect on the compacted layer of the pile, and can be applied to the treatment of hard sludge composting.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1: Please refer to Figures 1 to 7 :

[0028] This utility model proposes an automatic turning and composting device for sludge composting, comprising: a turning and composting device frame 1, which is fixedly connected to a turning and composting guide frame 2; the turning and composting guide frame 2 is an integrated hollow structure with an arc-shaped top and bottom, and a turning and composting drive mechanism 3 is provided on its right side; an active rotating shaft 4 and a driven rotating shaft 5, which are symmetrically distributed inside the turning and composting guide frame 2 through bearings, wherein the active rotating shaft 4 is drivenly connected to the turning and composting drive mechanism 3, and the driven rotating shaft 5 is arranged parallel to the bottom of the active rotating shaft 4; a chain plate transmission assembly, including two chain plate active sprockets 401 fixed to the active rotating shaft 4, two chain plate driven sprockets 501 fixed to the driven rotating shaft 5, and a conveying chain plate 6 meshing with the outer circumference of the sprockets; turning and composting baffles 601 are evenly distributed on the outer surface of the conveying chain plate 6; and a sludge inlet 2. 01 and 202 are respectively located at the bottom and top of the turning guide frame 2. The turning drive 3 drives the active rotating shaft 4 to rotate. The rotation of the active rotating shaft 4 drives the conveying chain plate 6 to rotate at high speed in the high-speed meshing of the chain plate active sprocket 401 and the chain plate driven sprocket 501. This drives the turning plate 601 to quickly pass through the sludge inlet 201. As the turning equipment frame 1 drags the turning guide frame 2 through the sludge compost, the sludge compost enters the interior of the turning guide frame 2 through the sludge inlet 201 and comes into contact with the plate folding edge 602. The turning plate 601 and the plate folding edge 602 rapidly impact and cut the sludge compost, causing it to be broken up and then moving upward with the turning plate 601 and thrown out through the 202, thus realizing the efficient turning process of the sludge compost.

[0029] In this embodiment, the sludge inlet 201 is located at the bottom front of the turning guide frame 2, and the discharge port 202 is located at the top rear of the turning guide frame 2. When the turning guide frame 2 moves forward under the load of the turning equipment frame 1, the sludge inlet 201 first contacts the sludge, and as the turning guide frame 2 moves forward, the sludge enters the interior of the turning guide frame 2 through the sludge inlet 201 and contacts the turning plate 601. The discharge port 202 is located at the upper rear end of the turning guide frame 2. The sludge generates inertia during the turning process by the turning plate 601. Under the action of inertia, the sludge is thrown backward and downward through the discharge port 202, realizing the mixing and turning of the sludge. As the turning guide frame 2 moves, the sludge compost is turned backward and piled up again.

[0030] In this embodiment, the sludge-shoveling plate 601 located at the front of the inside of the sludge-shoveling guide frame 2 is inclined upwards and forwards, and the angle between the sludge-shoveling plate 601 and the conveyor chain plate 6 is seventy degrees. The sludge-shoveling plate 601 located behind the conveyor chain plate 6 is inclined downwards and backwards. The sludge-shoveling plate 601 with this structure can more effectively shovel up the sludge and carry it away upwards.

[0031] In Example 2, based on Example 1, the end of the conveyor chain plate 6 is attached to the inner wall of the turning and throwing guide frame 2. The outer edge of the turning and throwing plate 601 is bent to form a plate flange 602, which is attached to the inner wall of the turning and throwing guide frame 2. The end of the turning and throwing plate 601 is attached to the turning and throwing guide frame 2. The active rotating shaft 4 is coaxial with the top arc plate of the turning and throwing guide frame 2, and the driven rotating shaft 5 is coaxial with the bottom arc plate of the turning and throwing guide frame 2. This arrangement ensures that the turning and throwing plate 601 and the plate flange 602 are attached to the inner surface of the turning and throwing guide frame 2, preventing sludge from falling through gaps during the turning and throwing process and causing equipment blockage, which would increase operating resistance. During the forward movement of the turning and throwing guide frame 2, the sludge is cut and impacted by the high-speed moving plate flange 602 and enters the interior of the turning and throwing guide frame 2, impacting and crushing the clump structure in the sludge, and improving the breaking of hard clumps.

[0032] The working principle of this embodiment is as follows: First, the power mechanism in the frame 1 of the turning and composting equipment drives the turning and composting guide frame 2 to move towards the sludge compost. The turning and composting drive component 3 is activated. Through the cooperation of the turning and composting drive component 3, the active rotating shaft 4 and the driven rotating shaft 5, the conveying chain plate 6 is driven to rotate at high speed inside the turning and composting guide frame 2. As the turning and composting guide frame 2 moves forward, the sludge compost enters the turning and composting guide frame 2 through the sludge inlet 201. After being cut and impacted by the high-speed moving baffle 602, it enters the turning baffle 601. With the movement of the turning baffle 601, it is driven upward. When the turning baffle 601 moves to the position of the discharge port 202, the turning baffle 601 changes its trajectory under the drive of the conveying chain plate 6 and flips downward. The sludge above the turning baffle 601 is quickly thrown backward through the discharge port 202 under the action of inertia and piles up again on the ground behind the turning and composting guide frame 2, realizing the automatic turning and composting of sludge compost.
