Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sludge treatment, in particular to a quantitative dosing system for river sludge solidification. BACKGROUND

[0002] The existing river sludge solidification treatment device generally includes a conveying mechanism for pumping sludge out of the river and a stirring mechanism for stirring the sludge. After the sludge is pumped out of the river by the conveying mechanism, a solidifying agent is added to the inside of the sludge, and the solidifying agent and the sludge are stirred by the stirring mechanism. The solidifying agent and the sludge can be fully mixed, the sludge can be gradually dehydrated and solidified, and the sludge can be discharged to other places for recycling and treatment.

[0003] In the prior art, a utility model patent with publication (announcement) number CN210974384U and the name of a river sludge dewatering and solidification device is disclosed. It includes a mounting seat, a sludge treatment box arranged on the mounting seat, a water storage tank, and a feeding mechanism for feeding sludge into the sludge treatment box. A dosing tank for adding reagents is fixedly arranged above the sludge treatment box. A support frame is arranged on the mounting seat outside the sludge treatment box. The dosing tank is supported on the support frame, and one end of the dosing tank facing the sludge treatment box is provided with a reagent injection port. A stirring mechanism is arranged in the sludge treatment box. A discharge port is arranged on the side wall of the sludge treatment box and is closed by a closure. The sludge treatment box and the water storage tank are connected in communication through a drainage pipe connected with a water pump. In the utility model, the sludge is subjected to solid-liquid separation in the sludge treatment box, so that the solid substances in the separated and treated sludge can be landfilled, thereby reducing the possibility of reducing the productivity of fish ponds or farmlands caused by pouring sludge into the fish ponds or farmlands.

[0004] The device of the patent can separate the solid substances and water in the sludge, which facilitates the operator to separate and treat the solid substances and water in the sludge, and reduces the possibility of reducing the productivity of fish ponds or farmlands caused by pouring sludge into the fish ponds or farmlands. However, the device of the patent still has the following technical problems in use: (1) Since the device of the patent does not have a quantitative mechanism for the solidifying agent, the device of the patent cannot add the solidifying agent quantitatively according to the actual amount of river sludge to be treated, which affects the use effect of the device; (2) Since the device of the patent cannot screen different specifications of the solidifying agent and the agglomerated sludge according to the actual use requirements, different specifications of the agglomerated sludge are likely to agglomerate together to form larger agglomerates, which makes it difficult for the workers to treat them subsequently, thereby reducing the overall practicability of the device. SUMMARY

[0005] The present application relates to the technical field of sludge treatment, in particular to a quantitative dosing system for river sludge solidification.

[0006] The technical problem solved by the present application is:

[0007] (1) the existing equipment is inconvenient to add the solidifying agent according to the actual need of the amount of river silt;

[0008] (2) the existing equipment is inconvenient to screen different specifications of the agglomerates of the solidifying agent and the silt according to the actual use demand, and then the agglomerates of different specifications are prone to gather together to form larger agglomerates, and the subsequent processing of the agglomerates by the workers is difficult.

[0009] The present application can be realized by the following technical scheme: a quantitative dosing system for river silt solidification, comprising a silt treatment box, a dosing pipe being fixedly connected to the top end of the silt treatment box, an axial flow runner being rotatably connected to the inner cavity of the silt treatment box, the axial flow runner being rotated by continuously introducing silt into the inner cavity of the silt treatment box, a quantitative dosing mechanism being arranged in the inner cavity of the silt treatment box, the quantitative dosing mechanism comprising a trigger rod being synchronously rotated with the axial flow runner and being rotatably connected to the inner cavity of the silt treatment box, and a trigger switch being fixedly installed in the inner cavity of the silt treatment box and being electrically connected to the electric control valve on the dosing pipe.

[0010] Further technical improvements of the present application are that a first separation plate for distinguishing the specifications of the agglomerates of the solidifying agent and the silt is slidably connected to the inner cavity of the silt treatment box below the axial flow runner.

[0011] Further technical improvements of the present application are that a second separation plate for separating water, the solidifying agent and the agglomerates of the silt is fixedly installed in the inner cavity of the silt treatment box below the first separation plate.

[0012] Further technical improvements of the present application are that a driving mechanism for sliding the first separation plate up and down in the inner cavity of the silt treatment box is arranged in the inner cavity of the silt treatment box, the driving mechanism comprising a cylinder being fixedly connected to the silt treatment box and being slidably connected to the first separation plate, a cylindrical cam being rotatably connected to the inner cavity of the cylinder and being fixedly connected to the axial flow runner, a first sliding block being slidably connected to the inner wall of the cylinder and being fixedly connected to the first separation plate, and an arc-shaped plate being fixedly installed on the side of the first sliding block away from the inner wall of the cylinder and being matched with the cylindrical cam.

[0013] Further technical improvements of the present application are that a second sliding block being fixedly connected to the first separation plate is slidably connected to the inner wall of the cylinder on the side opposite to the first sliding block, and the second sliding block is fixedly connected to the first sliding block.

[0014] Further technical improvements of the present application are that a letting-in plate is fixedly connected between the second sliding block and the first sliding block.

[0015] Further technical improvements of the present application are that a plurality of pressing blocks being uniformly distributed are fixedly installed at the bottom end of the first separation plate, and the pressing blocks are arranged in a staggered manner with the separation holes in the first separation plate.

[0016] Further technical improvements of the present application are that the inner cavity of the sludge treatment box is rotationally connected with a shaft flow runner fixedly connected with a raking plate for raking the agglomerates formed by the solidifying agent and the sludge on the second separation plate.

[0017] Compared with the prior art, the present application has the following beneficial effects:

[0018] 1、The rotation of the shaft flow runner facilitates the synchronous rotation of the trigger rod fixedly connected with the rotating rod. When the trigger rod is about to rotate a circle in the inner cavity of the sludge treatment box, the trigger rod will abut against and press the hemisphere in the inner cavity of the sludge treatment box. When the hemisphere is compressed to the limit, the trigger rod completes a circle of rotation. At this time, the hemisphere will contact the trigger switch. Since the trigger switch is electrically connected with the electric control valve on the dosing pipe, the electric control valve will supply the solidifying agent in the inner cavity of the dosing box into the inner cavity of the sludge treatment box. When the trigger rod rotates again, it will contact the trigger switch again. At this time, the trigger switch will disconnect the power supply of the electric control valve. This reciprocating cycle facilitates the quantitative addition of the solidifying agent according to the actual need for treating the amount of river sludge. The use amount of the solidifying agent is controlled by the number of rotations of the shaft flow runner, which facilitates the accurate use of the solidifying agent and improves the overall practicality of the equipment.

[0019] 2、The rotating rod rotates at the same time, driving the cylindrical cam fixedly connected therewith to rotate. Through the cooperation of the cylindrical cam and the arc-shaped plate on the first sliding block, the up-down sliding of the first sliding block facilitates the synchronous up-down sliding of the second sliding block, and further facilitates the up-down reciprocating sliding of the first separation plate in the inner cavity of the sludge treatment box. Through the up-down movement of the first separation plate, the agglomerates of different specifications of solidifying agent and sludge are screened. After separation, the smaller agglomerates fall to the second separation plate. In the process of up-down movement of the first separation plate, the pressing block at the bottom end of the first separation plate will press the agglomerates on the second separation plate, thereby facilitating the acceleration of the separation of the agglomerates and water. In this process, the rotation of the raking plate facilitates the position exchange of the agglomerates on the second separation plate, thereby further accelerating the separation of the agglomerates and water, thereby facilitating the improvement of the overall working efficiency of the equipment and facilitating the satisfaction of different use requirements of the user.
