[0032] This embodiment provides a mortar dry mixing device, see Figure 1-Figure 5As shown, it includes a stirring chamber 1, a motor 2 is installed on the upper part of the stirring chamber 1, the motor 2 is connected to the stirring rod 21, the stirring rod 21 extends into the stirring chamber 1, and a plurality of blades are connected to the side of the stirring rod 21. The side wall of the stirring chamber 1 is connected to a feeding pipe 3, and the feeding pipe 3 is bent. An air suction hood 31 is provided on the outside of the opening of the feeding pipe 3, and the air suction hood 31 is connected to one end of the air pipe 4. The other end of the air pipe 4 is connected to the filter chamber 5. A fan 51 is installed at the end of the filter chamber 5 away from the air pipe 4, and a filter plate 52 is provided in the filter chamber 5.
[0033] In the above embodiment, the stirring chamber 1 is used to place the raw materials for the mixed mortar, and the motor 2 installed on the upper part of the stirring chamber 1 drives the stirring rod 21 to rotate in the stirring chamber 1, and a plurality of blades are connected to the side of the stirring rod 21, which can increase the contact area between the stirring rod 21 and the mixed raw materials so that the stirring rod 21 can mix the raw materials more evenly during the rotation process. The side wall of the stirring chamber 1 is connected to the feeding pipe 3, and the feeding pipe 3 is used to add the dry-mixed raw materials of the mortar into the stirring chamber 1. The feeding pipe 3 is bent, which can make the raw materials fall more slowly in the feeding pipe 3 to avoid stirring up more dust during the addition of raw materials. An air hood 31 is provided at the opening of the feeding pipe 3. The air hood 31 is connected to the filter chamber 5 via the air pipe 4. A fan 51 is installed at the end of the filter chamber 5 away from the air pipe 4, and a filter plate 52 is installed inside the filter chamber 5. When the dry-mixed mortar powder is poured into the feeding pipe 3, the powder will collide with the wall of the feeding pipe 3, generating dust. The fan 51 is turned on to suck the air out of the filter chamber 5, creating a negative pressure inside the filter chamber 5, causing the air in the air pipe 4 to flow into the filter chamber 5. The air pipe 4 draws in the air from the air hood 31. Because the air hood 31 is mounted outside the opening of the feeding pipe 3, it draws in the powder dust around the opening of the feeding pipe 3. The powder dust enters the filter chamber 5 through the air pipe 4. The filter plate 52 is installed inside the filter chamber 5, and the raw material particles in the dust are retained in the filter chamber 5 by the filter plate 52. Optionally, multiple filter plates 52 may be provided within the filter chamber 5 to enhance the filtering effect of the filter chamber 5. Air passing through the filter plates 52 is drawn out of the filter chamber 5 by the fan 51, thereby collecting and retaining dust generated during the filling process of the raw material powder. This prevents dust generated during the filling process from becoming airborne and polluting the air, thereby causing respiratory damage to workers. Furthermore, the collection of the raw material powder allows for secondary recycling and reuse of the raw material, thereby improving raw material utilization efficiency and reducing production costs.
[0034] In one embodiment of the present application, see Figure 1 As shown, a cutting blade 32 is provided on the inner side of the opening of the feeding tube 3 .
[0035] In the above embodiment, the raw materials for the dry mix of mortar are usually packaged and transported in packaging bags. When adding raw materials, the packaging bags need to be broken. Breaking the raw material packaging bags outside the feeding tube 3 will cause the raw materials to leak out and scatter outside, causing dust. A cutting blade 32 is provided on the inner side of the opening of the feeding tube 3, which can be used to extend the bottom end of the raw material packaging bag into the feeding tube 3. The packaging bag is cut by the cutting blade 32, and the raw materials enter the feeding tube 3 directly from the broken part of the packaging bag. After the raw materials have leaked out, the packaging bag can be pulled out from the pipe mouth of the feeding tube 3, which improves the convenience of breaking the raw material packaging bag. The cutting blade 32 is provided in the feeding tube 3 to prevent accidental touch, which is beneficial to improving safety.
[0036] In one embodiment of the present application, see Figure 4 As shown, a baffle 33 is provided in the feeding pipe 3 , and the upper end of the baffle 33 is rotatably connected to the upper wall of the feeding pipe 3 through a rotating shaft 331 .
[0037] In the above embodiment, the baffle 33 is in the feeding tube 3, and the bottom end of the baffle 33 contacts the lower wall of the feeding tube 3, so that the feeding tube 3 is initially in a closed state. The upper end of the baffle 33 is rotatably connected to the upper wall of the feeding tube 3 via the rotating shaft 331, so that the baffle 33 can deflect around the rotating shaft 331. When raw material powder is added to the feeding tube 3, as shown in FIG. Figure 4 For example, the raw material powder slides down along the inner wall of the feeding tube 3, and the falling raw material powder pushes the bottom end of the baffle 33 to deflect upward to realize the opening of the baffle 33 in the feeding tube 3. After the raw material powder flows through the feeding tube 3 and enters the stirring chamber, the lower end of the baffle 33 naturally falls and the feeding tube 3 is in a closed state. That is, the falling raw material powder can push the baffle 33 open and enter the stirring chamber 1 due to the falling kinetic energy of its own gravity. After the raw material powder flows in, the baffle 33 is in a closed state again. The closing of the baffle 33 can prevent the dust stirred up by the raw material powder in the stirring chamber 1 from overflowing from the pipe mouth of the feeding tube 3 during stirring.
[0038] In one embodiment of the present application, see Figure 1 As shown, a guardrail 311 is provided at the opening of the air hood 31 .
[0039] In the above embodiment, the guardrail 311 provided at the opening of the air hood 31 serves to block and protect the air hood 31, preventing debris such as raw material packaging bags from being sucked into the air hood 31 and causing blockage of the trachea 4, or preventing the staff's clothes from being sucked into the air hood 31, which is beneficial to improving the stability and safety of the operation of the device.
[0040] In one embodiment of the present application, see Figure 2 As shown, the upper end of the stirring chamber 1 is connected to a vent pipe 6 , and a filter bag 61 is provided at the pipe opening of the vent pipe 6 .
[0041] In the above embodiment, the stirring chamber 1 is in a closed state. When a large amount of raw materials enter the stirring chamber 1, the air in the stirring chamber 1 will be compressed and ejected outward from the feeding pipe 3. The outflow of gas will cause a large amount of dust to overflow, which will affect the smoothness of the raw materials entering. The upper end of the stirring chamber 1 is connected to a vent pipe 6, which allows gas to flow out of the vent pipe 6 to balance the air pressure in the stirring chamber 1. The mouth of the vent pipe 6 is covered with a filter bag 61 to prevent the raw material powder from overflowing through the vent pipe 6. Furthermore, a cap is provided at the mouth of the vent pipe 6 to seal the vent pipe 6 when the stirring chamber 1 is stirring.
[0042] In one embodiment of the present application, see Figure 5 As shown, a discharge valve 7 is installed at the bottom of the stirring chamber 1, and the discharge valve 7 is connected to the material guide pipe 71.
[0043] In the above embodiment, after the mortar raw materials in the stirring chamber 1 are mixed, the mortar material can be discharged by opening the discharge valve 7, and the material guide pipe 71 connected to the discharge valve 7 can be used to connect the packaging bag for packaging the mortar material.
[0044] In one embodiment of the present application, see Figure 1 As shown, a bracket 8 is installed at the bottom of the stirring chamber 1.
[0045] In the above embodiment, the bracket 8 installed at the bottom of the stirring chamber 1 is used to support the stirring chamber 1 to prevent the stirring chamber 1 from being displaced or tipped over when the motor 2 drives the stirring rod 21 to rotate in the stirring chamber 1. In addition, the bracket 8 supports the stirring chamber 1 and maintains a certain height from the ground, so that the material guide tube 71 at the bottom of the stirring chamber 1 can be connected to the packaging bag to take out the material.
[0046] During the actual use of this application: when pouring the dry-mixed powder of mortar into the feeding tube 3, the powder will contact and collide with the wall of the feeding tube 3 to generate dust. Turn on the fan 51 to suck out the air in the filter chamber 5, so that negative pressure is generated in the filter chamber 5, and the air in the trachea 4 flows into the filter chamber 5. The trachea 4 sucks in the air in the suction hood 31. Because the suction hood 31 is mounted on the outside of the opening of the feeding tube 3, the suction hood 31 will suck in the powder dust around the opening of the feeding tube 3. The powder dust enters the filter chamber 5 through the trachea 4. A filter plate 52 is provided in the filter chamber 5. The raw material particles in the dust are retained in the filter chamber 5 by the filter plate 52. Optionally, multiple filter plates 52 are provided in the filter chamber 5 to improve the filtering effect of the filter chamber 5. Figure 3 For example, multiple filter plates 52 can be arranged in the filter chamber 5, and the mesh size of the filter plates 52 arranged from right to left can be reduced in sequence to grade and screen different raw material powders, facilitating the subsequent recycling of the raw materials. The air passing through the filter plates 52 is drawn out of the filter chamber 5 by the fan 51, thereby collecting and retaining dust generated during the filling of the raw material powder.
[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
