Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically a purification device for concrete production. Background Technology

[0002] Concrete refers to artificial stone made by mixing cement as the main binder with water, sand, and gravel, and, when necessary, chemical admixtures and mineral admixtures, in appropriate proportions, and then uniformly mixing, compacting, molding, and curing.

[0003] During the concrete production process, the cement needs to be screened before being mixed in to remove impurities such as packaging bag fragments and lumps, in order to ensure the quality of the concrete.

[0004] Some cement screening equipment uses a rotating screen tube installed inside the shell to screen the cement. The cement screened through the screen tube falls into the shell and is discharged through the discharge pipe at the bottom of the shell. In order to facilitate the discharge of cement from the shell, the bottom of the shell is set in a funnel shape. However, since cement is a dry granular material with poor fluidity, material often accumulates at the bottom of the shell, which needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a purification device for concrete production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A concrete production impurity removal device includes an upper cover fixedly mounted on a frame. The bottom of the upper cover is open, and a hopper is located below the upper cover. Multiple vibrating motors are fixedly mounted at the bottom of the hopper. The hopper is elastically connected to the frame. A rubber sleeve is fitted over the top of the hopper and the bottom of the upper cover. Pressure plates are provided at corresponding locations on the outer sides of the rubber sleeve and the outer walls of the upper cover and the hopper. The pressure plates are fixedly connected to the corresponding upper cover and hopper by multiple screws. A screen tube is rotatably mounted inside the upper cover. Multiple screen holes are provided through the outer wall of the screen tube. A cover cylinder is fixedly installed through one side of the outer wall of the upper cover. The screen tube is inclined, and its lower end is located inside the cover cylinder. A discharge pipe is provided at the lower end of the outer wall of the cover cylinder. A geared motor for driving the screen tube is fixedly mounted on the outer wall of the upper cover. A feeding hopper is fixedly installed through the top of the upper cover, and the discharge end of the feeding hopper is located inside the top of the screen tube.

[0008] As a further embodiment of this utility model: multiple springs are provided below the hopper, and connecting sleeves are fixedly installed on the hopper and the frame at corresponding positions to each spring, with both ends of the spring located inside the corresponding connecting sleeves.
