Description

Technical Field

[0001] This utility model relates to the field of sand and gravel separator technology, and more specifically, to a concrete sand and gravel separator. Background Technology

[0002] A concrete sand and gravel separator is a device used to separate and recycle sand, stone, aggregate and cement slurry from waste concrete. It is widely used in concrete mixing plants, construction sites and other scenarios to achieve resource reuse and environmental protection goals.

[0003] A concrete sand and gravel separator is disclosed in Chinese patent document CN218423978U, in which concrete is filtered, intercepted and transported by setting up a cylinder and a spiral conveying shaft that cooperate with each other.

[0004] However, concrete waste contains various waste materials such as sand, gravel, stones, and aggregates. When the above method is used to separate sand and gravel from concrete waste, large particles such as sand and gravel directly contact the spiral blades in the screw conveyor shaft, which can easily cause jamming and wear of the spiral conveyor blades.

[0005] Furthermore, the above-mentioned scheme has a single filtration method when recycling concrete waste, and cannot further separate large particles such as sand and gravel and small particles such as fine aggregates, resulting in poor separation effect. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the problems existing in the prior art, this utility model provides a concrete sand and gravel separator to solve the technical problem mentioned in the background art that the existing concrete sand and gravel separator has poor recycling and separation effect on concrete waste.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A concrete aggregate separator includes a separation chamber, a screening screen plate above the separation chamber, an elastic support structure between the screening screen plate and the separation chamber, a vibrating motor on the screening screen plate, a feed hopper above the screening screen plate, an arc-shaped filter screen plate inside the separation chamber, a rotating shaft coaxially mounted above the arc-shaped filter screen plate, the rotating shaft being rotatably mounted on the separation chamber via bearings and connected to a drive motor, spiral conveying blades on the rotating shaft in conjunction with the arc-shaped filter screen plate, a discharge pipe on the side wall of the separation chamber in conjunction with the arc-shaped filter screen plate, and a sewage discharge pipe at the bottom of the separation chamber.

[0011] The present invention is further configured such that a discharge pipe is provided at the bottom of the feeding hopper, and a diversion plate is provided inside the feeding hopper in conjunction with the discharge pipe. The discharge pipe can more accurately guide the concrete waste entering the feeding hopper to the top of the screening screen plate. The diversion plate can make the concrete waste entering the feeding hopper enter the discharge pipe evenly and fall downward, thereby improving the uniformity of the distribution of concrete waste on the screening screen plate.

[0012] The present invention is further configured such that a support seat is provided on the side of the separation box, a connecting seat is provided on the side of the feed hopper, and a support column is provided between the connecting seat and the support plate. The stable installation of the feed hopper above the screening screen plate can be achieved through the cooperation of the support seat, the connecting seat and the support column.

[0013] The present invention is further configured such that the elastic support structure includes a connecting plate, two sets of which are arranged above and below the connecting plate, and a support spring is arranged between the two sets of connecting plates. The two sets of connecting plates are respectively connected to the separation box and the screening screen plate. Through the cooperation of the connecting plate and the support spring, the screening screen plate can be elastically supported and installed on the separation box. Thus, when the vibrating motor is running, the screening screen plate can be effectively vibrated and screened to separate sand, gravel and stones in concrete waste.

[0014] The present invention is further configured such that the screening mesh includes a mesh body, and a protective side plate is provided on the side of the mesh body. The mesh body is used to screen large particles such as sand and stones in concrete waste, and the protective side plate can prevent concrete waste from splashing outward during the screening process.

[0015] The present invention is further configured such that a guide plate is provided at the bottom end of the protective side plate, and the guide plate is inclined inward to the top of the interior of the separation box. Under the action of the guide plate, the concrete waste after being screened by the screening screen can fall more stably and accurately onto the arc-shaped filter screen, thereby achieving further screening and filtration of the concrete waste.

[0016] The present invention is further configured such that the edge of the spiral conveying blade is provided with a cleaning scraper. When the rotating shaft drives the bolt conveying blade to rotate, it can simultaneously drive the cleaning scraper to rotate, thereby scraping and cleaning the inner wall of the arc-shaped filter screen, ensuring the filtration effect of the arc-shaped filter screen and avoiding clogging.

[0017] The present invention is further provided that the side wall of the separation box is provided with a support leg, and the bottom end of the support leg is provided with a fixed foot. The support leg and the fixed frame can achieve overall stable support. The fixed foot can be connected and locked to the ground by means of burying or using fixed ground nails.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a concrete sand and gravel separator, which has the following features:

[0020] Beneficial effects:

[0021] 1. This utility model sets up a screening screen plate and installs it above the separation box through an elastic support structure. At the same time, a vibration motor is set on the screening screen plate. When concrete waste falls onto the screening screen plate through the feed hopper and discharge pipe, the vibration motor is activated. Under the action of the vibration motor, the screening screen plate can be driven to vibrate, thereby vibrating and screening the concrete waste, intercepting large particles such as sand and gravel, and conveying them downward through the screening screen plate, thus achieving effective separation of large particles such as sand and gravel from the concrete waste.

[0022] 2. In this utility model, an arc-shaped filter screen is provided inside the separation box and below the screening screen. The filter diameter of the arc-shaped filter screen is smaller than that of the screening screen. As a result, small particles of aggregate that are not intercepted by the screening screen can be intercepted by the arc-shaped filter screen, which can further enhance the separation effect during concrete waste recycling.

[0023] 3. This utility model has a rotating shaft, a spiral conveying blade, and a drive motor that work together on the arc-shaped filter screen. When it is necessary to clean the concrete waste intercepted on the arc-shaped filter screen, the drive motor can be started. The drive motor controls the rotating shaft to drive the spiral conveying blade to rotate, so that the concrete waste intercepted on the arc-shaped filter screen can be discharged out through the discharge pipe, realizing the automatic cleaning of the concrete waste on the arc-shaped filter screen, thereby enhancing the recycling and separation effect and efficiency of concrete waste. This utility model adopts a dual separation method, which can enhance the sand and gravel separation effect of concrete waste in the recycling process. Attached Figure Description
