Slurry screening equipment for concrete manufacturing

Abstract

The utility model relates to the technical field of concrete manufacturing, and discloses slurry screening equipment for concrete manufacturing, which comprises a screening tank, a cylinder, a screening drum, a circular plate, a first discharge port, an optical shaft, an annular plate, a first driving part and a second driving part. The use process is longitudinal, under the driving of the first driving piece, the cylinder can rotate, and then the screen drum is driven to rotate. And under the action of centrifugal force, the concrete slurry can be screened. And the material particles meeting the requirements are collected in the screen tank, and the material particles not meeting the requirements stay on the screen. After pulp screening is completed, under driving of the second driving piece, the optical axis can do linear motion, and then the annular plate is driven to do reciprocating motion. Therefore, materials adhered to the inner wall of the screen tank and the outer wall of the screen drum are scraped, and screen pulp is thoroughly cleaned. In addition, due to the fact that the first driving piece and the second driving piece are both located outside the screening tank, the first driving piece and the second driving piece can be prevented from making contact with mortar. Therefore, faults such as shutdown are prevented, and smooth operation of pulp screening and cleaning work is guaranteed.

Description

Technical Field

[0001] The present application relates to the technical field of concrete manufacturing, for example, to a slurry screening device for concrete manufacturing. Background Art

[0002] A related art (publication number: CN218608376U) discloses a concrete slurry screening device, including a slurry screening tank. A cleaning assembly for cleaning mortar adhering to the inner wall of the slurry screening tank is provided inside the slurry screening tank, and the cleaning assembly includes a first motor, a screw rod, a scraper and a brush. The first motor is installed on the top of the slurry screening tank. The screw rod is connected to the rotating end of the first motor. The scraper is sleeved around the screw rod. The brush is installed on the bottom wall of the scraper.

[0003] In the process of implementing the above embodiments, it is found that there are at least the following problems in the related art:

[0004] Since the cleaning component is set inside the slurry screening tank, the screw rod will come into contact with the mortar raw materials, resulting in a large amount of mortar particles adhering to the surface of the screw rod. Although the brush can scrape off some mortar particles, it is still prone to jamming. This makes the screw rod unable to operate normally until the first motor stops. Therefore, there is a hidden danger of failure, which affects the smooth progress of the cleaning work.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.
