Problems solved by technology

[0004] The above existing technical solutions have the following defects: a large amount of ash powder is stuck on the surface of the crushed and sieved material, if the material with ash powder is directly used to prepare recycled concrete, it will affect the coarse aggregate of recycled concrete The ratio between the fine aggregate and the gel material will affect the interface bonding strength between the gel material and the aggregate, and ultimately affect the quality of the finished concrete

Embodiment 1

[0040] refer to figure 1 , is a concrete waste recycling device disclosed by the present invention, comprising a first bracket 1 and a crusher 2 arranged on the top thereof, a screening machine 4 is provided on one side of the crusher 2, and a discharge port 21 at the bottom of the crusher 2 is below There is a material guide trough 22 inclined between the feed end of the screening machine 4, the end of the material guide chute 22 close to the crusher 2 is higher than the end close to the sieving machine 4, and the side of the material guide chute 22 is tilted with a feeding mechanism 3, The higher end of the feeding mechanism 3 is located above the material guide trough 22. The screening machine 4 includes a second bracket 41 and a U-shaped bracket 42 arranged on the top of the second bracket 41. 2. At one end, the side wall of the U-shaped fixed frame 42 is protruded with a fixed plate 421, and a spring 422 is provided between the top of the leg 411 of the second support 41 ...

Embodiment 2

[0046] A method for reusing concrete waste, comprising the steps of:

[0047] S1: Throw the tested concrete test block into the crusher 2 for crushing;

[0048] S2: The materials or concrete leftovers crushed by the crusher 2 are screened and cleaned at the screening machine 4;

[0049] S3: The screened and cleaned materials are transported to a fixed location for storage via the first conveyor belt 61, and are dried when passing through the drying mechanism 7.

[0050] The aggregates are cleaned while being screened, and the aggregates are dried while being transported. This ensures dry and clean aggregates while shortening the processing flow and is easy to operate.

Abstract

The invention relates to a concrete waste recycling device and method. The device comprises a first support, a crusher, a screening machine, a guide chute and a feeding mechanism, wherein the screening machine comprises a second support, a U-shaped fixing frame and a vibrating motor; a fixing plate protrudes out of the side wall of the U-shaped fixing frame; a spring is arranged between the top ofa supporting leg of the second support and the fixing plate; at least one filter screen is arranged on the U-shaped fixing frame and is parallel to the long edge of the U-shaped fixing frame; the filter screens are vertically arranged in parallel; the apertures of the filter screens from the upper layer to the lower layer are gradually reduced; a cleaning mechanism is arranged above the screeningmachine; a transmission mechanism is correspondingly arranged on one side, far away from the crusher, of the screening machine; and a drying mechanism is arranged above the transmission mechanism. According to the device, ash adhered to the surface of the materials is removed while the concrete materials are screened, so that the surface of the materials is kept clean, the proportion of each material is accurately controlled when a user subsequently prepares the concrete, the interfacial strength between the gel material and the aggregate can be enhanced, and the quality of the recycled concrete is ensured.

Description

technical field [0001] The invention relates to the technical field of recycling concrete waste, in particular to a device and method for recycling concrete waste. Background technique [0002] With the improvement of construction technology, the country accelerates the construction of infrastructure projects, and the application of concrete in the construction market is increasing. At the same time, the requirements for concrete quality and environmental protection are becoming more and more stringent. Concrete must meet certain standards before it can be used. , so it is necessary to prepare concrete test blocks for concrete performance testing. After the test is completed, the test blocks are generally discarded directly, resulting in a waste of resources; some concrete residues generated during the construction process are collected centrally and are often allowed to solidify naturally. If it is directly discarded in the natural environment, the recycling and reuse of co...
