Description

Technical Field

[0001] This utility model relates to the field of concrete mixer technology, specifically to a dust control device for mixing machinery. Background Technology

[0002] Dust control devices for mixing machinery are environmentally friendly devices used to reduce dust pollution generated during the operation of mixing equipment. They reduce dust emissions and improve the working environment while meeting environmental protection requirements through technologies such as source suppression, process control, or end-of-pipe treatment. Existing dust control devices combine dust collectors to absorb diffused dust.

[0003] However, the dust control method using vacuum cleaners involves diffusion followed by adsorption, which has a lag effect. Furthermore, the effectiveness of vacuum cleaners decreases under heavy workloads, and maintenance costs are high. Therefore, a dust control device using a stirring mechanism is needed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a dust control device for stirring machinery to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a dust control device for stirring machinery, comprising:

[0006] A forced mixer includes a support base, a mixing chamber, and a feed inlet. The mixing chamber is fixed inside the support base, and the feed inlet is located at the upper end of the mixing chamber.

[0007] An anti-diffusion assembly includes a protective cover, a top cover, a rotating shaft, and a first baffle. The protective cover is fixed to the upper three sides of the support base, the top cover is fixed to the upper end of the protective cover, the rotating shaft is rotatably connected to the inside of the protective cover, and the first baffle is welded to the rotating shaft.

[0008] Furthermore, the anti-proliferation component also includes reinforcing plates, which are fixed to the outside of the protective cover and are evenly distributed.

[0009] Furthermore, the anti-diffusion component also includes a first adhesive strip, one end of which is fixed to both ends of the first baffle, and the other end of which is attached to the inner wall of the protective cover.

[0010] Furthermore, there are four first baffles arranged in a symmetrical ring.

[0011] Furthermore, a dual-shaft stirring rod is rotatably connected inside the mixing chamber, and a discharge port is provided on the side of the mixing chamber.

[0012] Furthermore, it also includes a bonding assembly, which includes a fixing block, a connecting shaft, a torsion spring, and a second baffle. The fixing block is fixed to both ends of the first baffle away from the rotating shaft. One end of the connecting shaft is rotatably connected to the side of the fixing block, and the other end is fixed to the side of the second baffle. The torsion spring is sleeved on the connecting shaft, with one end fixed to the side of the fixing block and the other end fixed to the side of the second baffle.

[0013] Furthermore, the bonding assembly also includes a second adhesive strip, one end of which is fixed to the first baffle and the other end of which is fixed to the second baffle.

[0014] This utility model has the following beneficial effects:

[0015] This invention, through its anti-diffusion component, ensures that when the feeding device pours material into the mixing chamber from above the inlet, it first falls onto the first baffle. Under gravity, the first baffle drives the rotating shaft to rotate, and then the subsequent first baffle continues to rotate to the point where the material falls. Simultaneously, the rotation of the first baffle causes the first adhesive strip to move and adhere to the inner wall of the mixing chamber. The rotating first baffle presses dust into the mixing chamber. This design, through active blocking and dynamic sealing via mechanical structure, achieves source dust control, avoiding the lag problem of "diffusion followed by adsorption" in vacuum cleaner dust control methods. Its low energy consumption, high reliability, and easy maintenance make it particularly suitable for high-dust, high-load scenarios such as construction sites and mixing plants, combining economic efficiency with environmental friendliness.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-2 As shown, this utility model is a dust control device for stirring machinery, comprising:

[0025] A forced mixer includes a support base 10, a mixing chamber 11, and a feed inlet 12. The mixing chamber 11 is fixed inside the support base 10, and the feed inlet 12 is located at the upper end of the mixing chamber 11.

[0026] A dual-shaft stirring rod is rotatably connected inside the mixing chamber 11, and a discharge port is opened on the side of the mixing chamber 11;

[0027] The support base 10 provides support. The mixing chamber 11 is used for mixing concrete. The feed inlet 12 is used to feed raw materials into the mixing chamber 11. A dual-shaft mixing rod is installed inside the mixing chamber 11. The mixing rod is driven to rotate by a motor. A chamber door is set at the discharge port on the other side. The chamber door is opened and closed by a hydraulic control system that controls the hydraulic rod.

[0028] The anti-proliferation assembly includes a protective cover 20, a top cover 22, a rotating shaft 23, and a first baffle 24. The protective cover 20 is fixed to the upper three sides of the support base 10, the top cover 22 is fixed to the upper end of the protective cover 20, the rotating shaft 23 is rotatably connected to the inner side of the protective cover 20, and the first baffle 24 is welded to the rotating shaft 23.

[0029] The anti-proliferation component also includes a reinforcing plate 21, which is fixed to the outside of the protective cover 20 and is evenly distributed.

[0030] The anti-diffusion component also includes a first adhesive strip 25, one end of which is fixed to both ends of the first baffle 24, and the other end of which is attached to the inner wall of the protective cover 20.

[0031] The first baffle 24 consists of four pieces, arranged symmetrically in a ring;

[0032] The protective cover 20 and the top cover 22 provide protection, the reinforcing plate 21 provides reinforcement, the rotating shaft 23 facilitates the rotation of the first baffle 24, the first baffle 24 provides blocking, and the first rubber strip 25 can seal the gap between the two ends of the first baffle 24 and the inner wall of the protective cover 20.

[0033] Working principle:

[0034] When the feeding device pours the material into the mixing chamber 11 from above the inlet 12, it first falls onto the first baffle 24. Under the action of gravity, the first baffle 24 drives the rotating shaft 23 to rotate. The first baffle 24 then continues to rotate to the place where the material falls. As the first baffle 24 rotates, it drives the first rubber strip 25 to move against the inner wall of the mixing chamber 11. The rotating first baffle 24 presses the dust into the mixing chamber 11.

[0035] This step achieves source dust control through active isolation and dynamic sealing of mechanical structures, avoiding the lag problem of "diffusion before adsorption" in the dust control method of vacuum cleaners. Its low energy consumption, high reliability and easy maintenance make it particularly suitable for high dust and high load scenarios such as construction sites and mixing plants, combining economy and environmental protection.

[0036] Please see Figure 3 As shown, this embodiment, based on the above embodiment, further includes:

[0037] The bonding assembly includes a fixing block 30, a connecting shaft 31, a torsion spring 32, and a second baffle 33. The fixing block 30 is fixed to both ends of the first baffle 24 away from the rotating shaft 23. One end of the connecting shaft 31 is rotatably connected to the side of the fixing block 30, and the other end is fixed to the side of the second baffle 33. The torsion spring 32 is sleeved on the connecting shaft 31, and one end is fixed to the side of the fixing block 30, and the other end is fixed to the side of the second baffle 33.

[0038] The bonding assembly also includes a second adhesive strip 34, one end of which is fixed to the first baffle 24 and the other end is fixed to the second baffle 33;

[0039] The fixing block 30 provides support, the connecting shaft 31 provides connection, facilitating the rotation of the second baffle 33, the torsion spring 32 has a reset function, the second baffle 33 allows the first baffle 24 to fit against the feeding device, and the second rubber strip 34 can seal the gap between the first baffle 24 and the second baffle 33.

[0040] Working principle:

[0041] The feeding device pours the raw material into the mixing chamber 11. The falling raw material causes the first baffle 24 below to rotate downwards, and the first baffle 24 behind rotates accordingly, causing the second baffle 33 to rotate to the feeding device. The second baffle 33 adheres to the feeding device, causing the connecting shaft 31 to rotate around the fixed block 30. The first rubber strip 25 bends in the opposite direction. When the feeding device is removed, the second baffle 33 returns to its original position under the action of the torsion spring 32.

[0042] This step can further reduce the channel space for dust to diffuse outward above the feed inlet 12, thereby reducing the amount of dust diffusion.
