Description

Technical Field

[0001] This utility model relates to the field of mixer technology, specifically a mixer with an exhaust and purification device. Background Technology

[0002] A mixer is a mechanical device that uses mechanical force and gravity to uniformly mix two or more materials. During the mixing process, it can also increase the contact surface area of ​​the materials to promote chemical reactions and accelerate physical changes.

[0003] The horizontal mixer consists of a U-shaped container, ribbon agitator blades, and transmission components. The long, U-shaped cylindrical structure ensures minimal resistance in the movement of the mixed materials (powders, semi-fluids) within the cylinder. The forward and reverse rotating ribbons are mounted on the same horizontal axis, creating a low-power, high-efficiency mixing environment. The ribbon blades are typically double or triple-layered; the outer spiral gathers the material from both sides to the center, while the inner spiral transports the material from the center to both sides, creating more vortices in the flow, accelerating the mixing speed and improving mixing uniformity. A belt pulley drives a cycloidal reducer; compared to the high torque of gear reducers, the elastic connection of the belt drive offers the advantage of protecting the transmission components under overload conditions.

[0004] However, during the powder mixing process, powder and dust will be raised inside the horizontal mixer while the materials are being mixed. During the discharge process after mixing, the dust will be raised along with the discharged material, causing pollution to the working environment. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0022] Please see Figures 1-4 In this utility model, a mixer with an exhaust and purification device includes a base 1, a mixer body 2 fixedly installed on the top of the base 1, two feed valves 3 opened on the top of the mixer body 2, an air guide groove 4 and a discharge groove 5 opened inside the base 1, the air guide groove 4 and the discharge groove 5 are connected to each other on opposite sides, an air guide filter 6 is installed inside the air guide groove 4, an exhaust fan 7 is fixedly connected to the left end of the air guide groove 4 by bolts, a discharge valve 8 is fixedly installed at the bottom of the mixer body 2, the bottom of the discharge valve 8 is connected and cooperates with the discharge groove 5, a sealing plate 9 is hinged to the right side of the discharge groove 5, and a positioning component 10 is installed on the right side of the mixer body 2.

[0023] In this invention, the base 1 serves as the device support. During use, different powders are simultaneously fed in through two feed valves 3, then the feed valves 3 are closed. The mixer body 2 is then started to mix the materials. After mixing, the feed valves 3 and 8 are opened, allowing the discharged material to enter the discharge trough 5. Simultaneously, the exhaust fan 7 is activated to extract air, using the air guide filter 6 to extract and filter dust raised inside the mixer body 2. This ensures that the powder contained within is filtered into the discharge trough 5 and discharged synchronously. After the material is completely discharged, the discharge chute 5 opens, and the material flows outward. At this time, the feed valve 3 is closed, and the inside of the discharge chute 5 is drawn into a negative pressure state, so dust will not overflow until the material is completely discharged from the discharge chute 5. This achieves the advantages of the device in purifying the exhaust air, adsorbing and filtering the dust, and purifying the air inside the tank. It solves the problem in the existing horizontal mixer that powder and dust are raised during the mixing of materials, and the dust is raised with the discharge after mixing, causing pollution to the working environment.

[0024] Please see Figure 1 , Figure 2 and Figure 4The air guide filter 6 includes a circular tube 61, an inclined filter screen 62, an inner connecting ring 63, and an air induced mechanism 64. The outer side of the circular tube 61 slides into the interior of the air guide groove 4. The left side of the inclined filter screen 62 is fixedly connected to the inner connecting ring 63. The left side of the inner connecting ring 63 is inserted into the interior of the circular tube 61. The inner connecting ring 63 is locked and fixed to the circular tube 61 by bolts. The air induced mechanism 64 is installed on the mixer body 2 and communicates with its interior. The air induced mechanism 64 is connected and cooperates with the right side of the inclined filter screen 62.

[0025] In this invention, the circular tube 61 serves as the mounting and positioning structure between the inclined filter screen 62 and the air guide trough 4, while also ensuring a tighter connection between it and the exhaust fan 7, resulting in better exhaust performance. The inner connecting ring 63 facilitates the installation, removal, and maintenance of the inclined filter screen 62. When the equipment discharges material, the dust is mainly inside the mixer body 2. At this time, the exhaust fan 7 draws the inside of the circular tube 61 into negative pressure, and the air intake mechanism 64 draws air from the top inside the mixer body 2 to extract the floating dust, which is then filtered by the inclined filter screen 62. After the material is completely discharged into the discharge trough 5, the feed valve 3 is closed, and the sealing plate 9 is opened to remove the mixture from the discharge trough 5. At this time, the inside is under negative pressure, and the dust is always drawn in and not discharged, thus ensuring the advantage of the device's exhaust and air purification effect.

[0026] Please see Figure 1 and Figure 3 The air intake mechanism 64 includes an L-shaped pipe 641 and a horizontal pipe 642. The horizontal section of the L-shaped pipe 641 is inserted into the right side of the inclined filter screen 62. The top of the L-shaped pipe 641 passes through and is fixedly connected to the interior of the mixer body 2 and is fixedly connected to the horizontal pipe 642.

[0027] In this invention, the L-shaped pipe 641 and the horizontal pipe 642 work together to discharge dust from the inside of the mixer body 2 during the discharge stage. The dust is then drawn out through the L-shaped pipe 641 and then leaks out through the inclined filter screen 62 after the material has completely entered the discharge trough 5. The extraction continues, so that no dust overflows in the initial and later stages of discharge.

[0028] Please see Figure 1 The positioning component 10 includes a fixed sleeve 101 and an L-shaped locking rod 102. The left side of the fixed sleeve 101 is fixedly connected to the right side of the mixer body 2. The vertical end of the L-shaped locking rod 102 passes through and slides to the bottom of the fixed sleeve 101. The outer side of the L-shaped locking rod 102 contacts and engages with the outer side of the closing plate 9.

[0029] In this utility model, the fixed sleeve 101 and the L-shaped lever 102 cooperate, and the L-shaped lever 102 slides vertically along the inside of the fixed sleeve 101 to block and open the closed plate 9.

[0030] Please see Figure 1 Among them, a sealing strip 91 is fixedly connected to the left side of the sealing plate 9, and the outer side of the sealing strip 91 is in contact with the outer side of the mixer body 2.

[0031] In this invention, the sealing strip 91 improves the sealing effect between the sealing plate 9 and the discharge trough 5.

[0032] Please see Figure 1 The discharge trough 5 has an inclined surface 51 inside, which is aligned with and connected to the inclined filter screen 62 at the same angle.

[0033] In this invention, by aligning the inclined surface 51 with the inclined filter screen 62 at the same angle and connecting them, the discharged material is smoothly discharged into the interior of the discharge trough 5 along the inclined surface 51, allowing the inclined filter screen 62 to quickly leak out after discharge, thus maintaining the ventilation effect.

[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
