Description

Technical Field

[0001] This application relates to the technical field of concrete, and particularly relates to a concrete sedimentation tank. Background Art

[0002] A sedimentation tank is a structure that uses sedimentation to remove suspended solids in water. Currently, after cleaning a concrete mixer truck, a large amount of concrete is mixed in its liquid. Usually, for recycling, after separating it through a sand and gravel separator, the liquid is usually passed into a sedimentation tank for sedimentation. The cement in the liquid will be deposited in the sedimentation tank, thereby achieving the recycling of water and concrete.

[0003] After retrieval, a Chinese utility model patent with the authorization announcement number CN209596625U discloses a concrete sedimentation tank, which includes a sedimentation tank body. The sedimentation tank body includes a bottom plate, a front side plate, a rear side plate, a left side plate, and a right side plate. A drainage hole is opened in the upper half of the rear side plate. A sludge pushing plate is slidably connected in the sedimentation tank body. The sludge pushing plate is parallel to the left side plate, and three side walls of the sludge pushing plate are respectively attached to the front side plate, the rear side plate, and the bottom plate. A driving assembly for driving the sludge pushing plate to move horizontally back and forth is arranged on the sedimentation tank body. A sludge discharge hole is opened on the right side plate. The lowest point of the sludge discharge hole is coplanar with the upper surface of the bottom plate. A sludge blocking block is clamped in the sludge discharge hole. This utility model has the advantage of facilitating the recycling of cement.

[0004] In the process of implementing this application, at least the following problems exist in this technology. During the use of this utility model, since the clear water in the sedimentation tank is separated from the concrete, the clear water cannot be pumped out, and thus it is not convenient to obtain the concrete in the sedimentation tank, which affects the working efficiency. Therefore, a concrete sedimentation tank is proposed to solve the problems raised above. Utility Model Content

[0005] Aiming at the deficiencies of the prior art, this application provides a concrete sedimentation tank, which has the advantage of facilitating the pumping out of clear water, and solves the problem that since the clear water in the sedimentation tank is separated from the concrete, the clear water cannot be pumped out, and thus it is not convenient to obtain the concrete in the sedimentation tank, which affects the working efficiency.

[0006] To sum up, this application provides the following technical solution: A concrete sedimentation tank includes a sedimentation tank body and two first mounting plates fixedly connected to the top of the sedimentation tank body. A water pumping mechanism is arranged on one side of the sedimentation tank body, and an opening and closing mechanism is arranged on one side of the sedimentation tank body;

[0007] The pumping mechanism includes a water pump fixedly connected to one side of the sedimentation tank body. One end of the water pump is fixedly connected with a hose, and the end of the hose far from the water pump is fixedly connected with a suction head. A filter screen is fixedly connected inside the suction head. The end of the water pump far from the hose is fixedly connected with a water tank;

[0008] The opening and closing mechanism includes a blanking door hinged to one side of the sedimentation tank body. A first hinge is fixedly connected to one side of the sedimentation tank body and at the top of the blanking door. A second hinge is fixedly connected to the side of the blanking door far from the sedimentation tank body. An electric push rod is hinged between the first hinge and the second hinge.

[0009] By adopting the above technical solution, through the setting of the water pump and the hose, it is convenient for the staff to hold the hose and extend it into the sedimentation tank body, and then pump out the clear water in the sedimentation tank body. By setting the filter screen, it can prevent the sand and gravel in the clear water from being absorbed, effectively preventing the water pump from being damaged, and at the same time preventing the concrete from being pumped out, which is convenient for the staff to extract the precipitated concrete later. By setting the electric push rod and the blanking door, and by setting the first hinge and the second hinge, the electric push rod can drive the blanking door to rotate, thus facilitating the discharge of the concrete outside the sedimentation tank body without the staff manually removing the mud guard, solving the problem that due to the separation of the clear water and the concrete in the sedimentation tank, the clear water cannot be pumped out, and thus it is not convenient to obtain the concrete in the sedimentation tank, affecting the work efficiency.

[0010] Further, a support sleeve is fixedly connected to one side of the sedimentation tank body close to the water pump. The hose passes through the support sleeve and is slidably connected thereto.

[0011] The beneficial effect of adopting the above further scheme is that by setting the support sleeve, the hose can be supported and stabilized on one side of the sedimentation tank body.

[0012] Further, the number of the electric push rods is two, and the two electric push rods are symmetrically distributed on one side of the sedimentation tank body.

[0013] The beneficial effect of adopting the above further scheme is that by setting two electric push rods, the stability of the opening and closing of the blanking door can be improved.

[0014] Further, a threaded rod is rotatably connected between the two first mounting plates. A threaded sleeve is threadedly connected to the outside of the threaded rod. The bottom of the threaded sleeve is fixedly connected with a connecting block, and a pushing plate is fixedly connected to the side of the connecting block far from the threaded sleeve.

[0015] The beneficial effect of adopting the above further scheme is that by setting the threaded rod and the threaded sleeve, when the threaded rod rotates, it can drive the threaded sleeve to displace, so that the threaded sleeve can drive the pushing plate to move, thus facilitating the pushing of the concrete.

[0016] Furthermore, the lower surface of the pushing plate is attached to the inner bottom wall of the sedimentation tank body, and a scraping plate is fixedly connected to one side of the pushing plate.

[0017] The beneficial effect of adopting the above further solution is that by arranging the scraping plate, the concrete can be scraped more cleanly.

[0018] Furthermore, a driving motor is fixedly connected to the side of the sedimentation tank body away from the water pump. A transmission gear is fixedly connected to the output shaft of the driving motor. One side of the first mounting plate is rotatably connected to a driven gear meshing with the transmission gear, and the driven gear is fixedly connected to one end of the threaded rod.

[0019] The beneficial effect of adopting the above further solution is that by arranging the driving motor to drive the transmission gear and the driven gear to rotate, the driven gear can drive the threaded rod to rotate.

[0020] Furthermore, two second mounting plates are fixedly connected to the back of the top of the sedimentation tank body. A limiting rod is fixedly connected between the two second mounting plates, and a limiting sleeve is slidably connected to the outside of the limiting rod.

[0021] The beneficial effect of adopting the above further solution is that by arranging the limiting rod and the limiting sleeve, the threaded sleeve and the pushing plate can be limited.

[0022] Furthermore, the number of the connecting blocks is two. The two connecting blocks are respectively fixedly connected to the bottoms of the threaded sleeve and the limiting sleeve. One side of the pushing plate away from the threaded sleeve is fixedly connected to the limiting sleeve through the connecting block.

[0023] The beneficial effect of adopting the above further solution is that by arranging two connecting blocks, it is convenient to support and fix the pushing plate, making its movement more stable.

[0024] Compared with the prior art, the present application provides a concrete sedimentation tank, which has the following beneficial effects:

[0025] 1. For this concrete sedimentation tank, by arranging the water pump and the hose, it is convenient for the staff to hold the hose and extend it into the sedimentation tank body, and then pump out the clear water in the sedimentation tank body. By arranging the filter screen, it can prevent the sand and gravel in the clear water from being absorbed, effectively preventing the water pump from being damaged, and at the same time preventing the concrete from being pumped out, which is convenient for the staff to extract the precipitated concrete later.

[0026] 2. The concrete sedimentation tank is provided with an electric push rod and a blanking door, and through the arrangement of a first hinge and a second hinge, the electric push rod can drive the blanking door to rotate, thus facilitating the discharge of concrete outside the sedimentation tank body. There is no need for workers to manually extract the mud guard, which solves the problem that since the clear water in the sedimentation tank is separated from the concrete, the clear water cannot be pumped out, and thus it is not convenient to obtain the concrete in the sedimentation tank, affecting the work efficiency.
