[0002] Concrete can be referred to as concrete for short. It refers to a kind of engineering composite material formed by cementitious materials. Usually concrete uses cement as a cementitious material, and sand and stone as aggregates, which are mixed with water in a certain proportion and then stirred into cement concrete. It is often used in construction and civil engineering, and is a widely used material.

[0003] After searching, the existing Chinese patent announcement number is: CN 216149339 U, which provides a dust removal device for producing ready-mixed concrete. This patent significantly improves the dust removal efficiency by providing a two-stage dust removal device.

[0004] Although the above patent can improve the dust removal efficiency, the above dust removal device for producing ready-mixed concrete still has the following problems: the deflector baffle extends the travel of the dust-laden airflow in the primary dust removal box, causing the dust-laden gas to continuously collide with the side walls of the box and the deflector baffle during the flow, causing the dust to fall on the inner wall of the box and the surface of the deflector baffle, and then due to the self-weight of the dust, gradually fall to the bottom of the primary dust removal box and settle. However, due to a certain friction between the dust and the deflector baffle, the dust will remain on the deflector baffle, which can easily cause some dust to accumulate on the deflector baffle.

[0005] In view of the above problems, a dust removal device for producing ready-mixed concrete is proposed. Utility Model Content

[0025] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0026] See also Figure 1-4 The utility model provides a technical solution: a dust removal device for producing ready-mixed concrete, comprising a support plate 1, a moving wheel 2 is arranged at the bottom of the support plate 1, a primary dust removal box 8 is fixedly installed on the top of the support plate 1, a secondary dust removal box 5 is fixedly installed on the top of the support plate 1, a second collecting box 7 and a first collecting box 6 are arranged on the top of the support plate 1, the second collecting box 7 is located at the bottom of the primary dust removal box 8, the first collecting box 6 is located at the bottom of the secondary dust removal box 5, a second connecting pipe 9 is connected between the secondary dust removal box 5 and the primary dust removal box 8, a negative pressure suction fan 3 is fixedly installed on the top of the support plate 1, a first connecting pipe 4 is connected to the negative pressure suction fan 3, and an end of the first connecting pipe 4 away from the negative pressure suction fan 3 is connected to the interior of the secondary dust removal box 5.

[0027] The dust hood on the support plate 1 is aligned with the feed port of the ready-mixed concrete mixing tank, and the negative pressure suction fan 3 is started to suck the dust-containing gas into the first-level dust removal box 8. After preliminary treatment of the dust-containing gas, the dust-containing gas enters the second-level dust removal box 5 through the second connecting pipe 9, and finally enters the negative pressure suction fan 3 through the first connecting pipe 4, and is then discharged into the atmosphere. When a lot of dust accumulates in the first-level dust removal box 8 and the second-level dust removal box 5, the discharge valve is opened to discharge the dust into the second collecting box 7 and the first collecting box 6, and then the dust collected in the second collecting box 7 and the first collecting box 6 is returned to the mixing tank for continued use, which is convenient for dust collection and reuse.

[0028] A filter screen 12 is fixedly installed inside the secondary dust removal box 5 .

[0029] The filter 12 is provided to facilitate filtering the gas entering the secondary dust removal box 5 and further filtering the dust.

[0030] A vibration box 10 is fixedly installed on the top of the primary dust removal box 8 and the secondary dust removal box 5, and a motor 11 is fixedly installed on the top of the vibration box 10. A rotating shaft 13 is rotatably connected inside the vibration box 10 and the secondary dust removal box 5. The upper end of the rotating shaft 13 is fixedly connected to the output end of the motor 11, and a cleaning brush 14 is fixedly installed on the lower end of the rotating shaft 13, and the cleaning brush 14 is in contact with the bottom of the filter 12.

[0031] Start the motor 11, so that the motor 11 drives the rotating shaft 13 to rotate, and then the cleaning brush 14 rotates, so as to clean the bottom of the filter 12, thereby preventing the filter 12 from being blocked, minimizing the risk of blockage of the filter 12, and facilitating the separation of the filtered dust from the filter 12.

[0032] A rotating shaft 13 is located at one end inside the vibration box 10 and is fixedly sleeved with a round-headed first pulley 15. A rotating shaft 17 is rotatably connected inside the vibration box 10. A second pulley 18 is fixedly sleeved on the rotating shaft 17. A belt 16 is transmission-connected between the second pulley 18 and the first pulley 15. An elastic rod 19 is fixedly installed on the rotating shaft 17. A knocking ball 20 is fixedly installed on the end of the elastic rod 19 away from the rotating shaft 17. A bump is fixedly installed inside the vibration box 10.

[0033] When the rotating shaft 13 rotates, the rotating shaft 17 is driven to rotate through the first pulley 15, the belt 16 and the second pulley 18, so that the knocking ball 20 knocks the protrusion inside the vibration box 10, which in turn causes the elastic rod 19 to deform, thereby causing the vibration box 10 to vibrate, and then the first-level dust removal box 8 and the second-level dust removal box 5 to shake, thereby facilitating the shaking off of the dust on the inner walls of the first-level dust removal box 8 and the second-level dust removal box 5, thereby realizing the cleaning of the first-level dust removal box 8 and the second-level dust removal box 5, minimizing the accumulation of dust inside the first-level dust removal box 8 and the second-level dust removal box 5, thereby facilitating the later dust treatment, and at the same time facilitating the cleaning of the dust on the deflection baffle inside the support plate 1 to prevent accumulation.

[0034] Working principle:

[0035] Start the negative pressure suction fan 3 to suck the dust-containing gas into the interior of the first-level dust removal box 8. After the dust-containing gas is preliminarily treated, the dust-containing gas enters the interior of the second-level dust removal box 5 through the second connecting pipe 9, and finally enters the negative pressure suction fan 3 through the first connecting pipe 4, and is then discharged into the atmosphere. When a lot of dust accumulates in the first-level dust removal box 8 and the second-level dust removal box 5, open the discharge valve to discharge the dust into the second collecting box 7 and the first collecting box 6, and then return the dust collected in the second collecting box 7 and the first collecting box 6 to the mixing tank for continued use, which is convenient for dust collection. Start the motor 11, so that the motor 11 drives the rotating shaft 13 to rotate, and then the cleaning brush 14 rotates, and then the bottom of the filter 12 is cleaned.

[0036] When the rotating shaft 13 rotates, the rotating shaft 17 is driven to rotate through the first pulley 15, the belt 16 and the second pulley 18, so that the knocking ball 20 knocks the protrusion inside the vibration box 10, which in turn causes the elastic rod 19 to deform, thereby causing the vibration box 10 to vibrate, and then the first-level dust removal box 8 and the second-level dust removal box 5 to shake, thereby facilitating the shaking off of the dust on the inner walls of the first-level dust removal box 8 and the second-level dust removal box 5, thereby realizing the cleaning of the first-level dust removal box 8 and the second-level dust removal box 5, and minimizing the accumulation of dust inside the first-level dust removal box 8 and the second-level dust removal box 5.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
