Description

Technical Field

[0001] This utility model relates to the field of concrete technology, specifically to a premixed concrete impurity filtration device with aggregate. Background Technology

[0002] Concrete aggregates refer to the granular loose materials that serve as the skeleton or filler in concrete. They are divided into coarse aggregates and fine aggregates. Coarse aggregates refer to pebbles, crushed stone, etc., while fine aggregates refer to natural sand, artificial sand, etc. Fine aggregates often contain impurities such as branches or iron filings.

[0003] Existing patent document CN219745474U discloses a concrete aggregate impurity filtration device, comprising a housing, buffer springs, a vibrating motor, a first filter screen, a second filter screen, and a base. The lower end of the housing is equipped with buffer springs and a vibrating motor, and the number of buffer springs is set to four. This invention solves the problems of existing concrete aggregate impurity filtration devices, such as difficulty in smooth material feeding, cleaning of residual impurities on the inner wall, and poor filtration effect. The drive motor rotates the stirring rod, stirring and moving the falling fine concrete aggregate, preventing blockage of the feeding port. It also enables faster feeding and screening of the fine concrete aggregate, improving screening efficiency. Furthermore, the addition of a scraper cleans the inner wall of the housing, preventing impurities from adhering to the inner wall.

[0004] Although the device has many beneficial effects, the following problems still exist: When the device is in use, the impurities on the filter plate flow into the box by gravity. When there is too much concrete to be filtered, the filter plate will become clogged, affecting the filtration and feeding process.

[0005] Secondly, precast concrete contains cement paste, sand, aggregate fragments, and other substances, which easily form a sticky paste that adheres to the filter screen surface. The continuous sinusoidal vibration of traditional vibrating motors is not enough to quickly remove such deposits. Utility Model Content

[0006] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0007] 1. Technical problems to be solved:

[0008] To address the aforementioned issues, when using this device, impurities on the filter plate flow into the housing due to gravity, and when there is too much concrete to filter, the filter plate may become clogged, affecting the filtration and material feeding process.

[0009] Secondly, precast concrete contains cement paste, sand, aggregate fragments, and other substances, which easily form a sticky paste that adheres to the surface of the filter screen. The continuous sinusoidal vibration of traditional vibrating motors is difficult to quickly remove such deposits, which is why this utility model was proposed.

[0010] Therefore, the purpose of this utility model is to provide a premixed concrete impurity filtration device with aggregate, which can clean impurities on the filter plate and accelerate the flow of impurities into the box; the device can also peel off the adhering substances on the surface of the filter screen.

Combined with gravity, the vibrating rod 403 slides back and forth in the groove 404. The vibrating rod 403 periodically impacts the filter screen c103, causing the attached substances on the filter screen c103 to separate from the filter screen c103. Under the action of gravity, the impurities flow to the discharge hopper 203.
