Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing, and particularly relates to a concrete aggregate cleaning device. Background Art

[0002] As an important aggregate for producing concrete, crushed stones usually contain soil and other impurities. If these impurities directly participate in the production and mixing of concrete without treatment, it will surely have an adverse effect on the quality of concrete. Therefore, before the crushed stones are put into the production process, it is necessary to clean them to remove the attached soil and impurities.

[0003] Currently, the mainstream cleaning devices on the market mainly rely on filters or filter cartridges for cleaning. During use, after the crushed stones are put into the device, water flow is used to wash away the dirt on their surfaces. However, the designs of these devices are relatively simple, and the cleaning effect is not ideal. There are often residues of soil and impurities on the crushed stones. At the same time, the existing filtering components are easily blocked by the debris washed down, which not only affects the water filtering effect but also further weakens the cleaning effect.

[0004] To solve the above problems, we designed a new type of concrete aggregate cleaning device. This device should achieve a more efficient cleaning effect through uniquely designed cleaning components; at the same time, effective measures should be taken to prevent the filtering components from being blocked, so as to ensure the smooth progress of the cleaning process. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a concrete aggregate cleaning device to solve the problems described in the background art.

[0006] The technical solution of the utility model is realized as follows:

[0007] A concrete aggregate cleaning device includes a bottom plate. At the upper end of the bottom plate, a first support and a second support are fixedly installed. A horizontally placed soaking cylinder is rotatably installed on the first support, and a horizontally placed flushing cylinder is rotatably installed on the second support. A hollow front spiral blade is fixedly installed on the inner wall of the soaking cylinder. A plurality of material lifting plates are also arranged on the inner wall of the soaking cylinder. A retaining ring is provided at the front end opening of the soaking cylinder, and the inside of the retaining ring is the feed inlet. A feed pipe and a water inlet pipe extending into the feed inlet are also provided on the bottom plate. The flushing cylinder includes a plurality of frame rods fixedly connected to the rear end pipe orifice of the soaking cylinder. The plurality of frame rods are arranged at equal angular intervals centered on the central axis of the soaking cylinder. The flushing cylinder also includes an edge ring fixedly connected to the rear ends of the plurality of frame rods. The flushing cylinder also includes a middle ring fixedly sleeved outside the middle parts of the plurality of frame rods. The middle ring is rotatably installed on the second support. A sieve plate is also connected between adjacent frame rods. The plurality of sieve plates and the plurality of frame rods together form the side wall of the flushing cylinder. A hollow rear spiral blade is fixedly installed on the inner side wall of the flushing cylinder. An installation seat is also fixedly installed on the bottom plate. A support frame extending into the hollow part of the rear spiral blade from the edge ring is fixedly installed on the installation seat. A water supply pipe is provided on the support frame, and a plurality of spray heads are provided on the water supply pipe. A driving component for driving the soaking cylinder to rotate is also provided on the bottom plate. A cleaning component for cleaning the sieve plate is also provided on the bottom plate.

[0008] When using the above solution, water is continuously injected into the soaking cylinder through the water inlet pipe. Due to the blocking and conveying of the front spiral blade, the water in the soaking cylinder gradually accumulates and increases, and continuously moves towards the rear end of the soaking cylinder following the conveying of the front spiral blade. The aggregate is put in from the feed pipe, and the feed pipe guides the aggregate into the soaking cylinder. The aggregate is soaked in water. As the soaking cylinder rotates, with the lifting and falling of the material lifting plates and the continuous backward conveying of the front spiral blade, the aggregate continuously tumbles in the accumulated water and rubs against each other, thereby removing the impurities attached to the surface of the aggregate. When the aggregate enters the flushing cylinder, the sewage with impurities also enters the flushing cylinder, and the sewage and impurities are discharged through the sieve plate. The aggregate continuously tumbles following the rotation of the flushing cylinder, and at the same time follows the rearward conveying of the rear spiral blade, and is washed on the surface by the water sprayed out by the spray heads during this process. Since most of the impurities on the aggregate have been softened and fallen off after soaking, when the aggregate enters the flushing cylinder, only some impurities that can be quickly removed remain attached to the surface. At this time, after flushing again, the remaining attached impurities can be quickly washed off.

[0009] By setting two cleaning components, namely the soaking cylinder and the flushing cylinder, this device realizes the cleaning steps of first soaking and then flushing the aggregate, improving the cleaning effect.

[0010] At the same time, a cleaning component is arranged outside the flushing cylinder of the device to quickly clean the sieve plate of the flushing cylinder, prevent the sieve plate from being blocked, and thus ensure the smooth progress of the cleaning process.

[0011] A further technical solution is that the cleaning component includes a plurality of vertical rods fixedly arranged on the bottom plate. A cross rod is commonly provided on the plurality of vertical rods, and a brush component is detachably installed on the cross rod. The brush component is used for brushing the sieve plate.

[0012] When using the above solution, when the flushing cylinder rotates, the stationary brush component continuously brushes the sieve plate of the flushing cylinder, timely cleaning the sieve plate and preventing the sieve plate from being blocked.

[0013] A further technical solution is that the brush component includes a mounting plate, the mounting plate is detachably installed on the cross rod, and bristles are provided on the mounting plate. The bristles abut against the sieve plate for brushing the sieve plate.

[0014] A further technical solution is that a plurality of sewage pipes are also provided on the bottom plate. The sewage pipes are arranged below the flushing cylinder for receiving the sewage discharged from the flushing cylinder.

[0015] A further technical solution is that a conveyor belt is also provided on the bottom plate. The conveyor belt is arranged below the outlet of the flushing cylinder for receiving the aggregate discharged from the flushing cylinder.

[0016] A further technical solution is that a gear ring is fixedly sleeved outside the soaking cylinder, and the driving component is drivingly connected with the gear ring.

[0017] The beneficial effects of the present utility model are as follows:

[0018] 1. Efficient cleaning steps: This solution realizes the double cleaning treatment of the aggregate by setting two cleaning components, namely the soaking cylinder and the flushing cylinder - soaking first and then flushing. Such steps can clean the aggregate more thoroughly and improve the cleaning effect.

[0019] 2. Ingenious design: The solution utilizes the blocking and conveying functions of the front spiral blade to collect the water in the soaking cylinder and move it backward, while driving the aggregate to roll in the accumulated water and rub against each other, effectively removing the surface impurities.

[0020] 3. Sieve plate cleaning mechanism: The cleaning component arranged outside the flushing cylinder can quickly clean the sieve plate, effectively prevent the sieve plate from being blocked, and ensure the smoothness of the cleaning process.

[0021] 4. Continuous processing capacity: This solution can continuously process the aggregate, improve the processing efficiency, and meet the requirements of large-scale production. Description of the Drawings
