Description

Technical Field

[0001] The utility model relates to the technical field of sludge brick making, in particular to a curing agent adding and mixing device for sludge brick making. Background Art

[0002] Traditional sludge treatment technologies mainly include sludge incineration, composting, landfill, etc. However, these methods have certain defects. In recent years, a new treatment method has emerged, which is to process sludge into bricks. This method can make full use of the organic matter and minerals in sludge and convert them into building materials with certain strength and stability. This can not only solve the problem of sludge treatment, but also meet the requirements of environmental protection and sustainable development. However, in the process of sludge brick making, a curing agent needs to be added to the sludge. Generally, a large amount of curing agent is directly fed into the sludge, and the inside of the sludge cannot be stirred in time, which will affect the uniformity of sludge curing. Content of the Utility Model

[0003] The purpose of the utility model is to solve the defect that adding a large amount of curing agent at one time in the prior art affects the uniformity of sludge curing, and to propose a curing agent adding and mixing device for sludge brick making.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] Design a curing agent adding and mixing device for sludge brick making, including a mixing bin. An installation shell is fixedly installed at the upper end of the mixing bin. A transmission frame is connected to the inner top of the installation shell through a motor. An expansion rod is fixedly installed at the end of the transmission frame. The expansion rod is inclined. Its lower end is fixedly connected with a linkage mechanism. The end of the linkage mechanism far away from the expansion rod penetrates and extends into the mixing bin and is fixedly installed with a conveying pipe. The length direction of the conveying pipe is parallel to the length direction of the expansion rod.

[0006] Preferably, the linkage mechanism includes a linkage rod. The upper end of the linkage rod is fixedly connected with the expansion rod. An outer circular seat is fixedly installed at the top of the mixing bin. An inner circular sleeve is movably arranged inside the outer circular seat. The lower end of the linkage rod movably penetrates the inner circular sleeve and extends into the mixing bin. A connecting pipe is also inserted inside the inner circular sleeve. A slider is fixedly installed on one side of the connecting pipe. The slider is slidably arranged on one side of the linkage rod. A limiting block is fixedly installed on the side of the connecting pipe far away from the slider. The limiting block penetrates and extends into the inner side wall of the inner circular sleeve. The lower end of the connecting pipe is fixedly connected with the conveying pipe and the upper end is fixedly connected with a supply mechanism.

[0007] Preferably, a mixing shaft is fixedly installed at the lower end of the part of the linkage rod extending into the mixing bin.

[0008] Preferably, the mixing shaft, the linkage rod and the telescopic rod are coaxially arranged, and the length direction of the connecting pipe is parallel to the length direction of the linkage rod.

[0009] Preferably, the supply mechanism includes a receiving box fixedly installed at the bottom of the installation shell. An insertion pipe is inserted into the upper end of the receiving box, and the end of the insertion pipe away from the receiving box is fixedly connected to the upper end of the connecting pipe.

[0010] Preferably, the cross-section of the receiving box is annular, and the central axis of the receiving box passes through the center of the outer circular seat.

[0011] Preferably, a liquid level sensor is fixedly installed inside the receiving box.

[0012] For a curing agent adding and mixing device for sludge brick making proposed by the present utility model, the beneficial effects are as follows: During the working process of the curing agent adding and mixing device for sludge brick making, the transmission frame can drive the mixing shaft to rotate at a certain inclination angle through the telescopic rod.

During the rotation of the conveying pipe, the curing agent can be dispersed and fed into the sludge, and the curing agent is added in small amounts and multiple times, which can improve the uniformity of the mixing of the sludge and the curing agent and improve the efficiency of sludge curing. While the linkage rod rotates, it can drive the mixing shaft to rotate, and the rotation of the mixing shaft can timely stir the sludge mixed with the curing agent solution. The telescopic rod can also drive the mixing shaft to move up and down reciprocally, which can increase the stirring range of the mixing shaft and improve the efficiency of stirring inside the sludge.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Embodiment 1: Refer to Figures 1-4 , a curing agent adding and mixing device for making bricks from sludge, including a mixing bin 1 for storing sludge inside. At the upper end of the mixing bin 1, an installation shell 2 is fixedly installed. At the top inside the installation shell 2, a transmission frame 14 is connected by a motor. The motor can drive the transmission frame 14 to rotate. At the end of the transmission frame 14, a telescopic rod 13 is fixedly installed. The telescopic rod 13 is inclined. As shown in the attached Figure 1 figure, at its lower end, it is fixedly connected to a linkage mechanism. The end of the linkage mechanism away from the telescopic rod 13 penetrates and extends into the mixing bin 1 and is fixedly installed with a delivery pipe 9. The length direction of the delivery pipe 9 is parallel to the length direction of the telescopic rod 13. The delivery pipe 9 is used to send the curing agent solution into the sludge.

[0020] The linkage mechanism includes a linkage rod 5. The upper end of the linkage rod 5 is fixedly connected to the telescopic rod 13. An outer circular seat 3 is fixedly installed at the top of the mixing bin 1. An inner circular sleeve 4 is movably arranged inside the outer circular seat 3. The center of the outer circular seat 3 coincides with the center of the inner circular sleeve 4. The inner circular sleeve 4 can rotate arbitrarily inside the outer circular seat 3. The lower end of the linkage rod 5 movably penetrates the inner circular sleeve 4 and extends into the mixing bin 1. A connecting pipe 6 is also inserted inside the inner circular sleeve 4. On one side of the connecting pipe 6, a slider 7 is fixedly installed. The slider 7 is slidably arranged on one side of the linkage rod 5. The linkage rod 5 can slide along the length direction of the connecting pipe 6 through the slider 7. On the side of the connecting pipe 6 away from the slider 7, a limit block 8 is fixedly installed. The limit block 8 penetrates and extends into the inner side wall of the inner circular sleeve 4. Under the limiting and positioning of the limit block 8, the connecting pipe 6 cannot move inside the inner circular sleeve 4, and the connecting pipe 6 is fixedly connected to the inner circular sleeve 4 relatively.

[0021] By driving the transmission frame 14 to rotate through the motor, the rotation of the transmission frame 14 will drive the telescopic rod 13 to rotate at a certain inclination angle. The rotation of the telescopic rod 13 will drive the linkage rod 5 to rotate at the same inclination angle. The rotation of the linkage rod 5 will drive the inner circular sleeve 4 to rotate inside the outer circular seat 3. The rotation of the inner circular sleeve 4 will drive the connecting pipe 6 to rotate at the same inclination angle. The rotation of the connecting pipe 6 will drive the delivery pipe 9 to rotate at the same inclination angle. The delivery pipe 9 rotates in the mixing bin 1 in an inclined state, which can increase the movement range of the delivery pipe 9 inside the sludge, can send the curing agent into the sludge in a dispersed state, and can facilitate the uniformity of mixing between the curing agent and the sludge inside.

[0022] The lower end of the connecting pipe 6 is fixedly connected to the conveying pipe 9, and the upper end is fixedly connected to the supply mechanism. The supply mechanism is used to provide the curing agent solution. The supply mechanism feeds the curing agent solution into the connecting pipe 6, the connecting pipe 6 feeds the curing agent solution into the conveying pipe 9, and the conveying pipe 9 feeds the curing agent solution into the sludge. At the lower end of the linkage rod 5 extending into the interior of the mixing chamber 1, a mixing shaft 12 is fixedly installed. The mixing shaft 12, the linkage rod 5, and the telescopic rod 13 are coaxially arranged. The length direction of the connecting pipe 6 is parallel to the length direction of the linkage rod 5. When the linkage rod 5 rotates, it will drive the mixing shaft 12 to rotate in an inclined state, and the interior of the sludge can be stirred through the mixing shaft 12. Moreover, the mixing shaft 12 is located on one side of the conveying pipe 9, and the sludge into which the curing agent is fed can be stirred in time through the mixing shaft 12, which helps the curing agent to be quickly mixed in the sludge. During the rotation of the telescopic rod 13, by starting the telescopic rod 13, the lower end of the telescopic rod 13 can drive the linkage rod 5 to reciprocate in the inner circular sleeve 4. The connecting pipe 6 will not move with the linkage rod 5 under the restriction of the limit block 8. When the linkage rod 5 moves, it will drive the mixing shaft 12 to reciprocate. The mixing shaft 12 will rotate at a certain inclination while moving, which can increase the range of sludge stirring.

[0023] Working principle: During the working process of the curing agent adding and mixing device for sludge brick making, starting the motor drives the transmission frame 14 to rotate. When the transmission frame 14 rotates, it will drive the telescopic rod 13 to rotate at a certain inclination. When the telescopic rod 13 rotates, it will drive the mixing shaft 12 to rotate through the linkage rod 5. When the linkage rod 5 rotates, it will drive the inner circular sleeve 4 to rotate. When the inner circular sleeve 4 rotates, it will drive the connecting pipe 6 to rotate. When the connecting pipe 6 rotates, it will drive the conveying pipe 9 to rotate. During the rotation of the conveying pipe 9, the curing agent is dispersed and fed into the sludge. When the linkage rod 5 rotates, it will also drive the mixing shaft 12 to rotate. The rotation of the mixing shaft 12 can timely stir the sludge mixed with the curing agent solution. At the same time, starting the telescopic rod 13 drives the linkage rod 5 to move. The linkage rod 5 will move in the inner circular sleeve 4. When the inner circular sleeve 4 moves, it will drive the mixing shaft 12 to move. The mixing shaft 12 can move up and down reciprocally while rotating, which can increase the range of the mixing shaft 12 stirring and improve the efficiency of stirring the interior of the sludge.

[0024] Embodiment 2: In Embodiment 1, during the rotation of the connecting pipe 6 and the conveying pipe 9, the supply mechanism provides the curing agent for the interior of the connecting pipe 6. In the general existing technology, the pipe body is directly connected to the external container storing the curing agent and the connecting pipe 6. Then, when the connecting pipe 6 rotates, it will drive the pipe body to rotate, and the pipe body will wind around the outside of the connecting pipe 6, making the connecting pipe 6 unable to rotate normally. Therefore, this embodiment is proposed. Refer to Figures 1-2, as another preferred embodiment of the present utility model, on the basis of Embodiment 1, the supply mechanism includes a receiving box 11. The receiving box 11 is fixedly installed at the bottom of the installation shell 2. The receiving box 11 stores a curing agent solution inside. The receiving box 11 is connected to a container outside for storing the curing agent solution. A liquid level sensor is fixedly installed inside the receiving box 11. The liquid level sensor can measure and control the liquid level of the curing agent inside the receiving box 11. The liquid level sensor is set at a specified height. When the height of the curing agent is lower than the measurement and control range of the liquid level sensor, it is necessary to send the curing agent into the receiving box 11 to keep the liquid level of the curing agent solution inside the receiving box 11 always within the specified range. An insertion pipe 10 is inserted into the upper end of the receiving box 11. The bottom of the insertion pipe 10 extends deep into the curing agent, ensuring that the height of the bottom of the insertion pipe 10 is always lower than the liquid level height of the curing agent. The end of the insertion pipe 10 away from the receiving box 11 is fixedly connected to the upper end of the connecting pipe 6. The insertion pipe 10 can send the curing agent into the connecting pipe 6. The cross-section of the receiving box 11 is circular. The central axis of the receiving box 11 passes through the center of the outer circular seat 3. When the connecting pipe 6 rotates, the connecting pipe 6 will drive the insertion pipe 10 to rotate. The insertion pipe 10, the connecting pipe 6, and the delivery pipe 9 all have fixed shapes. When the insertion pipe 10 rotates, it will rotate inside the receiving box 11. The insertion pipe 10 is always in contact with the curing agent solution inside the receiving box 11, and can always provide the curing agent inside the connecting pipe 6, which can solve the problem that the traditional pipe body will entangle the outside of the connecting pipe 6 and affect the normal supply of the curing agent.

[0025] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
