Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to a concrete batching device for environmental protection concrete production. Background Technique

[0002] Concrete is one of the most important civil engineering materials in modern times. It is prepared by mixing cementitious materials, granular aggregates (also known as aggregates), water, and additives and admixtures added as necessary in a certain proportion, and is formed into an artificial stone through uniform mixing, dense molding, and curing. Concrete has the characteristics of rich raw materials, low price, and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades.

[0003] In the Chinese patent with the publication number CN219926496U, a concrete batching device for environmental protection concrete production is disclosed. It drives a rotating rod through a first motor to continuously strike the lower end of a mesh plate with a striking block. The mesh plate vibrates under the action of a chute, a slider, and a spring, so as to screen large powdery materials and crush blocky powdery materials, improving the mixing effect of concrete.

[0004] In the above solution, the method of striking the filter screen is adopted to improve the screening efficiency of powdery materials. However, some severely agglomerated powdery materials are difficult to be put into subsequent mixing after being filtered out on the filter screen, which requires taking out these blocky materials. In the above solution, the filter screen is fixed in the powdery material box, and it can only be taken out by hand or fishing with tools by workers, with low efficiency. And there are still problems of slow filtering efficiency and concentrated discharging position of the filtered powdery materials only by striking the filter screen. Therefore, we provide a concrete batching device for environmental protection concrete production to solve the above problems. Content of the Utility Model

[0015] (III) Beneficial effects:

[0016] Compared with the prior art, the concrete batching device for environmental protection concrete production has the following beneficial effects:

[0017] In the present utility model, by combining the self-rotation and circumferential rotation of the screening tank, the screening efficiency of raw materials passing through the filter holes is effectively improved. The self-rotation of the screening tank helps the raw material particles to better pass through the filter holes and reduces the blockage phenomenon. The circumferential rotation helps to adjust the position of the raw materials, making the screening more uniform, thus solving the problem of low filtering efficiency in the traditional method. The circumferential movement of the screening tank helps to adjust the position of the raw materials entering the batching tank, avoiding the problem of uneven stirring caused by the raw materials concentrating in one area. The dynamic movement of the screening tank also helps the raw materials to be more evenly distributed in the batching tank, further improving the stirring effect and the quality of the final concrete.

[0023] As Figures 1-3 shown, the present invention provides a technical solution: a concrete batching device for environmental protection concrete production, including a batching tank 1, a support frame 4 and a ring 12.

[0024] A frustum 2 is rotatably connected to the batching tank 1, and a circumferentially arrayed mounting sleeve 7 is rotatably connected to the frustum 2. Each mounting sleeve 7 is detachably installed with a screening tank 9. Filter holes 10 are opened at the bottom of the screening tank 9, which can pour raw materials into the interior of the screening tank 9 and filter the raw materials through the filter holes 10 on the screening tank 9. The aperture of the filter holes 10 can also be adjusted according to the particle size of the raw materials. A baffle 13 is installed at the top end of the screening tank 9, and the baffle 13 can seal the opening of the screening tank 9. A blanking pipe 3 is fixedly communicated with the bottom surface of the batching tank 1, and the mixed raw materials in the batching tank 1 can be discharged through the blanking pipe 3.

[0025] Through holes 15 are opened on the mounting sleeve 7, limit grooves 16 are opened on the inner walls of the through holes 15. The middle section of the screening tank 9 is located in the through holes 15. A limit block 17 is fixedly connected to the screening tank 9, and the limit block 17 is inserted into the limit groove 16. When installing the screening tank 9, first pass the bottom end of the screening tank 9 through the through hole 15 and install it in the mounting sleeve 7, and limit the screening tank 9 by inserting the limit block 17 into the limit groove 16.

[0026] The support frame 4 is fixedly connected to the batching tank 1. A motor 5 is installed on the support frame 4. The output rotating shaft of the motor 5 is fixedly connected with a rotating shaft 6, and the bottom end of the rotating shaft 6 penetrates through the frustum 2 and extends below the frustum 2.

A stirring paddle 8 is fixedly connected to the rotating shaft 6, and the stirring paddle 8 is located in the batching tank 1. When the rotating shaft 6 drives the frustum 2 to rotate, the stirring paddle 8 will also stir the raw materials in the batching tank 1.
