Description

Technical Field

[0001] The utility model belongs to the technical field of screening equipment, and in particular relates to waste concrete separation equipment for concrete processing. Background Art

[0002] Concrete refers to an artificial stone made by mixing cement as the main cementing material with water, sand, gravel, and if necessary, chemical admixtures and mineral admixtures in appropriate proportions, and then evenly mixing, compacting, forming, and curing and hardening. It is widely used in modern construction and engineering. During the processing of concrete, some waste concrete will be generated. In order to facilitate the recycling of the waste concrete, it is often necessary to crush the waste concrete and then reuse it.

[0003] In the existing waste concrete separation equipment, only the large particles are initially crushed, screened and filtered, and the fine particles of waste concrete are collected and reused, which greatly reduces the utilization rate of waste concrete. In addition, the uniformity of the waste concrete after screening is low, and it needs to be processed again after separation and recovery, which affects the recycling efficiency of the waste concrete. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing waste concrete separation is mostly carried out by filtering the larger particles of waste concrete after preliminary crushing. The waste concrete particles obtained in this way have poor uniformity and need to be processed again, which makes the recycling efficiency of the waste concrete low.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is as follows: a waste concrete separation device for concrete processing, comprising an equipment shell, the interior of the equipment shell is respectively a separation chamber and a collection chamber from top to bottom, a feed hopper is arranged on the top side of the separation chamber, and a crushing roller group is arranged inside the feed hopper; a crushing roller is rotatably connected to the interior of the separation chamber, a spiral feeding plate is arranged on the surface of the crushing roller, a crushing seat is arranged below the crushing roller, and a groove matching the shape of the spiral feeding plate is arranged on the crushing seat, and a plurality of screening holes are arranged at the bottom of the crushing seat; the four corners of the bottom of the crushing seat are slidably connected to the bottom of the separation chamber through guide rods, and a compression spring is arranged on the outside of the guide rod between the crushing seat and the separation chamber; a collecting trough is arranged inside the collection chamber, a discharge port is arranged on one side of the bottom of the collecting trough through the equipment shell, and a spiral feeding rod is arranged inside the collecting trough.

[0006] As an improvement, the crushing roller group consists of two symmetrically arranged crushing rollers, and the crushing rollers are composed of multiple staggered crushing discs and rotating shafts, wherein the multiple crushing discs are fixed on the rotating shaft, the rotating shafts on both sides are meshed and connected by the same gears, and the rotating shaft on one side is connected to the first drive motor through a first synchronous belt.

[0007] As an improvement, the crushing roller is tangent to both sides of the separation chamber, and the crushing roller matches the shape of the top of the crushing seat, and one end of the crushing roller is connected to the second drive motor through a second synchronous belt.

[0008] As an improvement, the outer side of the pulverizing seat matches the shape of the interior of the separation chamber, the overall height of the top of the pulverizing seat is 1 / 2 of the height of the pulverizing roller, and a semicircular groove body matching the shape of the pulverizing roller is provided in the middle.

[0009] As an improvement, a material guide plate is provided at the bottom of the crushing seat outside the plurality of screening holes, the material guide plate is slidably connected to the bottom of the separation chamber, and the material guide plate is located inside the collecting tank.

[0010] As an improvement, the top of the collecting trough matches the shape of the collecting chamber, the width of both sides of the collecting trough gradually decreases from top to bottom toward the middle, and the discharge port and the spiral feeding rod are both located at the bottom of the collecting trough, and the end of the spiral feeding rod away from the discharge port is connected to a third drive motor.

[0011] The advantages of the utility model compared with the prior art are:

[0012] The waste concrete separation equipment can crush larger concrete fragments into smaller particles through the crushing roller group arranged in the feed hopper, and then enter the separation chamber. Through the grinding between the crushing roller and the crushing seat, the concrete blocks are ground more finely, and the proportion of recycled and separated waste concrete is increased. In addition, the uniformity of the concrete after grinding is higher, which avoids the time required for subsequent processing and improves the recycling efficiency.
