[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is made of cementitious materials, granular aggregates, water, and admixtures and admixtures added when necessary in a certain proportion. Concrete is an artificial stone made by uniform mixing, compacting, curing and hardening. Concrete has the characteristics of abundant 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 wide range of strength grades. These characteristics make its scope of use very wide. Among them, environmentally friendly concrete is concrete made by mixing waste steel slag discharged from steel mills and fly ash discharged from power plants with cement in a reasonable ratio. In the production of concrete, a large amount of fly ash is required, and fly ash needs to be stored in storage tanks.

[0003] However, during the fly ash feeding process, some fly ash will adhere to the side wall of the storage tank. When the fly ash attached to the inner wall of the storage tank has not been used for a long time, the fly ash will become damp and hardened, which will affect the quality of the fly ash in the storage tank after the next cycle of fly ash is injected into the storage tank.

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a concrete powder storage tank for environmentally friendly concrete production. Figure 1 and Figure 2 A concrete powder storage tank for environmentally friendly concrete production includes a storage tank 1, a circular ring 2 is slidably arranged in the storage tank 1, the circular ring 2 is located above the powder, the outer wall of the circular ring 2 abuts against the inner wall of the storage tank 1, the circular ring 2 slides along the depth direction of the storage tank 1, and a first driving member for driving the circular ring 2 to slide is arranged in the storage tank 1; a baffle plate 3 is arranged in the storage tank 1 and near the top, a gap is left between the baffle plate 3 and the inner wall of the storage tank 1, and the circular ring 2 is received in the gap between the baffle plate 3 and the storage tank 1.

[0023] While the storage tank 1 is unloading, the ring 2 is driven to slide by the first driving member, and the sliding of the ring 2 scrapes off the powder attached to the inner wall of the storage tank 1. The scraped powder falls on the powder to be processed and used. In the above process, the adhesion of the powder is reduced, the quality of the powder is improved, and the utilization rate of the powder is improved. At the same time, when the storage tank 1 is feeding, the possibility of the powder falling on the ring 2 is reduced under the blocking effect of the baffle plate 3.

[0024] Reference Figure 3 and Figure 4 In the embodiment of the present application, the first driving member includes a first motor 4 and a driving rope 5 arranged on the inner wall of the storage tank 1. The driving rope 5 is a steel wire rope. Two first motors 4 are provided. The two first motors 4 are respectively located at the top and bottom of the storage tank 1. The length direction of the output shaft of the first motor 4 is perpendicular to the axis direction of the storage tank 1. The two ends of the driving rope 5 are respectively wound on the output shaft of the first motor 4, and the ring 2 is fixedly arranged at the free end of the driving rope 5. When the powder on the inner wall of the storage tank 1 is scraped off, the first motor 4 below is started, and the first motor 4 winds up the driving rope 5. The winding of the driving rope 5 drives the ring 2 to move downward, and the ring 2 moves to scrape off the powder on the inner wall. The operation is simple and convenient.

[0025] Reference Figure 2In order to facilitate the driving rope 5 to drive the ring 2 to slide, a plurality of guide rods 6 are fixedly arranged in the storage tank 1. The guide rods 6 are parallel to the depth direction of the storage tank 1, and the ring 2 slides through the guide rods 6; the ring 2 is guided by the guide rods 6, which reduces the possibility of the ring 2 tilting, thereby facilitating the sliding of the ring 2.

[0026] Reference Figure 2 and Figure 3 Since the material stored in the storage tank 1 is powder, in order to reduce the adverse effect of the powder on the first motor 4, in the embodiment of the present application, a mounting box 7 is provided in the storage tank 1, and the mounting box 7 is fixedly arranged on the inner wall of the storage tank 1. The first motor 4 is located in the mounting box 7, and a through hole is opened on the mounting box 7 for the drive rope 5 to move out; under the action of the mounting box 7, the powder and the first motor 4 are relatively separated, thereby reducing the effect of the powder on the first motor 4, thereby facilitating the normal operation of the first motor 4.

[0027] Reference Figure 3 and Figure 4 In order to reduce the possibility of powder entering the installation box 7 through the through hole, a rubber ring 8 is embedded in the through hole, and the inner diameter of the rubber ring 8 is smaller than the outer diameter of the driving rope 5; under the action of the rubber ring 8, the powder is blocked, reducing the possibility of powder entering the installation box 7 through the through hole.

[0028] Reference Figure 3 and Figure 4 Furthermore, in the embodiment of the present application, a material cleaning piece is provided in the installation box 7, and the material cleaning piece is used for the powder material entering the installation box 7 through the driving rope 5. The material cleaning piece includes a mounting tube 9 arranged in the installation box 7, and the mounting tube 9 is connected to the through hole. A plurality of scrapers 10 are arranged in the mounting tube 9, and the driving rope 5 is clamped between adjacent and opposite scrapers 10. A removal tube 11 is connected to the mounting tube 9, and the removal tube 11 is inclined toward the bottom of the installation box 7, and the driving rope 5 is moved out vertically through the removal tube 11; when the driving rope 5 enters the installation box 7 through the through hole, the powder material is easily stuck in the winding seam of the driving rope 5. When the driving rope 5 enters the installation tube 9, the powder material stuck in the driving rope 5 is scraped off under the scraping action of the scraper 10, and the scraped powder material moves along the mounting tube 9 and is staggered with the first motor 4, further reducing the influence of the powder material on the first motor 4.

[0029] Reference Figure 3 and Figure 4 In order to facilitate the ventilation and cooling of the first motor 4, a ventilation pipe 12 is provided on the storage tank 1, one end of the ventilation pipe 12 is located outside the storage tank 1, and the other end is connected to the installation box 7; under the action of the ventilation pipe 12, it is convenient for the outside air to enter the installation box 7 through the ventilation pipe 12 to ventilate and cool the first motor 4.

[0030] Reference Figure 3 and Figure 4 In order to reduce the possibility of the powder in the storage tank 1 being wet and compacted due to the outside air, an opening and closing member for opening and closing the ventilation pipe 12 is provided on one side of the ventilation pipe 12 outside the storage tank 1. The starting member includes a rubber head inserted into the ventilation pipe 12, and the rubber head slides and blocks the ventilation pipe 12 to block the ventilation pipe 12.

[0031] Reference Figure 3 and Figure 4 In order to facilitate the removal of the powder in the installation tube 9, the end of the removal tube 11 away from the installation tube 9 is located in the ventilation tube 12. The powder removed from the removal tube 11 enters the ventilation tube 12, and then the powder is removed from the ventilation tube 12. The operation is simple and convenient.

[0032] The implementation principle of a concrete powder storage tank for environmentally friendly concrete production in the embodiment of the present application is as follows:

[0033] While the storage tank 1 is unloading, the first motor 4 is used to reel in the driving rope 5 to drive the ring 2 to slide. The sliding of the ring 2 scrapes off the powder attached to the inner wall of the storage tank 1. The scraped powder falls on the powder to be processed and used. In the above process, the adhesion of the powder is reduced, the quality of the powder is improved, and the utilization rate of the powder is improved. Under the action of the baffle plate 3, the possibility of the powder in the storage tank 1 falling on the top of the ring 2 is reduced, and the utilization rate of the powder is further improved.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
