Description

Technical Field

[0001] This utility model relates to the field of concrete mixer truck cleaning, and in particular to a concrete mixer truck cleaning device for concrete mixing plants. Background Technology

[0002] Concrete mixer truck cleaning equipment for concrete batching plants refers to equipment specifically designed for cleaning concrete mixer trucks. Its main function is to remove residual concrete, slurry, and other impurities from the mixer truck after mixing concrete, preventing the accumulation and solidification of residues that could clog the inside of the truck, ensuring the normal operation of the mixer truck, improving work efficiency, and extending the service life of the equipment. This equipment is typically installed inside the concrete batching plant.

[0003] Traditional concrete mixing plants typically discharge wastewater directly after using concrete mixer truck cleaning equipment, without recycling the stones and cement dust in the wastewater, which easily leads to resource waste. Secondly, the fixed location of traditional concrete mixer truck cleaning equipment requires the mixer truck's feed hopper to be aligned with the outlet, which requires a certain level of skill from the driver and is prone to accidents, wasting the time and energy of the staff.

[0004] Therefore, those skilled in the art have provided a cleaning device for concrete mixer trucks used in concrete mixing plants to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a concrete mixer truck cleaning device for concrete mixing plants. The device works by pouring the wastewater from cleaning the mixer truck into a filter frame, where a first filter screen removes the stones. The filtered wastewater then enters an inner tank to settle cement ash. After settling, the first chute is lifted to release the settled water into the outer tank. The filter frame is then lifted out, the stones are poured out for reuse, and the settling frame is removed. The settled cement ash is used for road paving, and the settled water can be used for the next truck wash, thus saving water resources.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A cleaning device for a concrete mixer truck used in a concrete mixing plant includes a base frame. A recycling mechanism is provided at the rear end of the base frame. The recycling mechanism includes an outer box located at the rear end of the base frame. An inner box is fixedly connected to the inner bottom surface of the outer box. A sedimentation frame is provided on the inner bottom surface of the inner box. A filter frame is slidably connected to the upper end of the inner wall of the inner box. Two locking blocks are fixedly connected to both sides of the front and rear outer walls of the filter frame. A first filter screen is fixedly connected to the inner wall of the filter frame. Water outlet grooves are provided at the lower ends of both sides of the outer walls of the inner box. A first sliding groove is provided on both sides of the inner box. A baffle is slidably connected inside the first sliding groove. A second sliding groove is provided at the lower ends of both sides of the inner box. A second filter screen is slidably connected to the inner wall of the second sliding groove. Two locking slots are provided at the front and rear ends of the upper surface of the inner box. The base frame is equipped with a moving mechanism, which includes a hydraulic column that is slidably connected inside the base frame. A bracket is fixedly connected to the upper surface of the hydraulic column. A motor is fixedly connected to the outer wall of one side of the bracket. A threaded rod is fixedly connected to the output end of the motor. A moving block is sleeved on the outer wall of the threaded rod. Limit rods are provided at the rear ends of the outer walls on both sides of the moving block. A connecting block is fixedly connected to the lower surface of the moving block. A water outlet tank is fixedly connected to the lower surface of the connecting block. The above technical solution involves pouring the wastewater from cleaning the mixer truck into a filter frame. The first filter screen removes the stones from the wastewater. The filtered wastewater then enters the inner tank to settle cement ash. After settling, the first chute is lifted to put the settled water into the outer tank. The filter frame is then lifted out, the stones are poured out for reuse, and the settling frame is lifted out. The settled cement ash is used for road paving, and the settled water can be used for the next truck wash, thus saving water resources.

[0007] Furthermore, the limiting rod passes through the moving block, the moving block slides on the outer wall of the limiting rod, and the connecting block slides on the lower surface of the inner wall of the bracket; The above technical solution uses a hydraulic device to lift the hydraulic column, making the height of the mechanism adjustable. Turning on the motor drives the threaded rod to rotate, causing the moving block to slide the water tank in the bracket. This allows the water in the water tank to be accurately poured into the mixing drum of the mixer truck for cleaning, without requiring the vehicle to be perfectly aligned with the equipment, saving time and effort.

[0008] Furthermore, a support base is fixedly connected to the lower surface of the base frame, and a pump is provided on one outer wall of the base frame; Through the above technical solution, the support base can stabilize the base frame, and the pump can draw water for cleaning.

[0009] Furthermore, an inlet valve is fixedly connected to the outer wall of the rear end of the pump, and an outlet pipe is fixedly connected to the upper surface of the pump; The above technical solution enables the pumping process.

[0010] Furthermore, a water outlet valve is fixedly connected to the upper surface of the water outlet pipe, and a corrugated pipe is provided on the upper surface of the water outlet valve. The end of the corrugated pipe away from the water outlet valve is fixedly connected to the water outlet tank. The above technical solution delivers water into the outlet tank via a corrugated pipe.

[0011] Furthermore, a fixing block is fixedly connected to the side of the rear outer wall of the bracket away from the motor, a slide rail is slidably connected to the front and rear ends of the lower surface of the outer box, and a drain pipe is provided on one side of the outer wall of the outer box; The above technical solution uses a fixing block to fix the corrugated pipe to the bracket.

[0012] Furthermore, a second handle is fixedly connected to both sides of the upper surface of the sedimentation frame, and a first handle is fixedly connected to the middle of the front end and rear end of the upper surface of the filter frame; Using the above technical solution, the sedimentation box is lifted out using the second handle, and the filter box is lifted out using the first handle.

[0013] Furthermore, the snap-fit ​​block engages with the snap-fit ​​slot; The above technical solution achieves the fixation of the filter frame.

[0014] This utility model has the following beneficial effects: 1. The present invention proposes a concrete mixer truck cleaning device for a concrete mixing plant. The wastewater after cleaning the mixer truck is poured into a filter frame. The first filter screen filters out the stones in the wastewater. The filtered wastewater enters the inner tank to settle out cement ash. After the sedimentation is completed, the first chute is lifted to put the settled water into the outer tank. Then the filter frame is lifted out, the stones are poured out and reused. The sedimentation frame is lifted out, the settled cement ash is used for road paving, and the settled water can be used for the next truck washing, thus saving water resources.

[0015] 2. The present invention proposes a cleaning device for a concrete mixing plant, which uses a hydraulic device to lift the hydraulic column, making the height of the mechanism adjustable.
