Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mortar mixing equipment, and in particular to dust removal equipment for mortar production. Background Technology
[0002] Dry mortar refers to a granular or powdery material made by physically mixing aggregates, inorganic cementitious materials, and additives in a certain proportion after drying and screening. It is transported to the construction site in bagged or bulk form and can be used directly after being mixed with water. It is also known as dry mortar powder, dry-mixed mortar, or dry-mixed powder. Some building adhesives also belong to this category. Dry mortar plays a role in bonding, padding, protection, and decoration in the construction industry by applying thin layers. It is widely used in construction and decoration projects.
[0003] In related technologies, after the dry mortar is produced, it needs to be filled into bags. However, dust will be generated during the filling process. When the dry mortar falls into the bag, dust will be generated. If the dust is inhaled by the workers, it will cause serious damage to their health.
[0004] A utility model patent with publication number CN217263495U discloses a dry-mixed mortar filling device, relating to the field of dry-mixed mortar production technology. This dry-mixed mortar filling device includes a device body and a dust collection mechanism. A cover is installed on the top and side walls of the device body. An installation pipe, communicating with the interior of the cover, is installed on the side wall of the device body. A drive motor is installed inside the installation pipe to drive the fan blades to rotate. A filter bag is installed inside the cover, with its bottom fixed to the bottom of the cover and its top connected to a slider. The drive motor drives the fan blades to rotate, achieving airflow inside the device body. Outside air enters the device body through the feed pipe, drawing dust into the cover through the air inlet. The filter bag filters the dust in the air, preventing it from scattering to the outside. Simultaneously, the drive motor drives the slider to move left and right, causing the filter bag to shake and preventing excessive dust accumulation on the filter bag, which could lead to blockage.
[0005] However, in similar solutions, when dry powder bags are used to hold mortar, the dust inside the mortar will be stirred up by the impact of the mortar itself and overflow from the bag opening. This will pollute the atmosphere, affect the cleanliness of the working environment, and affect the health of the workers. Utility Model Content
[0006] The purpose of this invention is to solve the problem that dust is easily raised when receiving materials at the discharge port of existing mortar mixing equipment, and to propose a dust removal device for mortar production.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] The mortar production dust removal equipment includes a discharge pipe installed at the bottom of the mixing tank, a feed pipe at the bottom of the discharge pipe, a dust removal pipe connected to the side wall of the feed pipe, and a dust collection box at the outlet end of the dust removal pipe.
[0009] Furthermore, a hollow cavity is formed in the side wall of the feeding pipe, and a dust suction hole is formed on the outer side wall of the hollow cavity. The hollow cavity is connected to the dust removal pipe.
[0010] Furthermore, the middle part of the dust removal pipe is connected to the connecting pipe, the end of the connecting pipe away from the dust removal pipe is connected to the interior of the hollow cavity, and a fan is provided at the end of the dust removal pipe away from the dust collection box.
[0011] Furthermore, the discharge pipe is a screw conveyor.
[0012] Furthermore, the discharge pipe is arranged in a horizontal direction.
[0013] Furthermore, the discharge pipe is arranged in an upward oblique direction.
[0014] Furthermore, the top of the feeding pipe is connected to the bottom of the dust collection box, and the feeding pipe is arranged in a vertical direction.
[0015] Compared with the prior art, this utility model provides a dust removal device for mortar production, which has the following beneficial effects:
[0016] This utility model of dust removal equipment for mortar production involves placing a packaging bag for dry mortar onto the feeding pipe, opening the discharge pipe, and allowing the dry mortar to flow into the feeding pipe and finally into the packaging bag. The dust removal pipe draws away the dust raised near the feeding pipe from the end of the feeding pipe and discharges it into the dust collection box, thereby reducing the amount of dust overflowing from the packaging bag. Compared with existing technologies, this effectively reduces the amount of dust entering the atmosphere.
[0017] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0028] 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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Reference Figure 1-8 The present invention relates to a dust removal device for mortar production, comprising a discharge pipe 2 installed at the bottom of the side wall of a mixing tank 1. The discharge pipe 2 is a screw conveyor. The advantage of using a screw conveyor is that when discharge is required, the screw conveyor mechanism is activated, and the screw conveyor drives the dry powder mortar material in the mixing tank 1 into the discharge pipe 2. When discharge is not required, the screw conveyor mechanism can be stopped. This can effectively prevent the discharge pipe 2 from being blocked and can also adjust the discharge speed.
[0030] A discharge pipe 3 is installed in the middle of the bottom of the discharge pipe 2. When in use, the opening of the packaging bag for holding dry mortar is put over the discharge port at the bottom of the discharge pipe 3. A dust collection pipe 4 is connected to the side wall of the discharge pipe 3. When the discharge begins, the dust of the mortar floating out of the opening of the packaging bag is sucked away through the dust collection pipe 4. A dust collection box 5 is installed at the outlet end of the dust collection pipe 4. The dust sucked away through the dust collection pipe 4 is discharged into the dust collection box 5 for collection. The dust collection box 5 is located below the mixing tank 1, and the dust collection pipe 4 is set at an incline.
[0031] A hollow cavity 301 is machined in the side wall of the feeding pipe 3. The hollow cavity 301 is a hollow and closed structure. Dust suction holes 302 are opened on the outer side wall of the hollow cavity 301. The dust suction holes 302 are distributed on the lower part and bottom end of the outer side wall of the feeding pipe 3. The hollow cavity 301 is connected to the dust removal pipe 4. When the dry powder mortar flows from the inside of the feeding pipe 3 into the packaging bag, the dust that is raised overflows from the bag opening. The dust removal pipe 4 forms a suction effect on the hollow cavity 301. The dust at the bag opening is sucked into the hollow cavity 301 through the dust suction holes 302, and then discharged into the dust collection box 5 through the dust removal pipe 4.
[0032] The dust removal pipe 4 is also inclined. The higher end of the dust removal pipe 4 is close to the discharge pipe 2. The middle part of the dust removal pipe 4 is connected to the connecting pipe 402. The end of the connecting pipe 402 away from the dust removal pipe 4 is connected to the interior of the hollow cavity 301. A fan 401 is installed at the end of the dust removal pipe 4 away from the dust collection box 5. The fan 401 blows air into the dust removal pipe 4. The air pressure in the dust removal pipe 4 is lower than the air pressure in the connecting pipe 402 and the hollow cavity 301. Under the action of air pressure, a suction effect is formed in the hollow cavity 301.
[0033] The discharge pipe 2 is installed horizontally, which can reduce the automatic outflow of dry mortar when the screw conveyor stops.
[0034] The discharge pipe 2 is installed in an upward oblique direction, not shown in the figure. Specifically, the end of the discharge pipe 2 away from the mixing tank 1 is higher than the end of the discharge pipe 2 close to the mixing tank 1, so as to prevent the material in the discharge pipe 2 from automatically flowing out when the screw conveyor stops.
[0035] The top of the discharge pipe 3 is connected to the bottom of the dust collection box 5. The discharge pipe 3 is set vertically. The material flowing from the mixing tank 1 to the discharge pipe 2 finally flows into the packaging bag through the discharge pipe 3.
[0036] Working principle: When in use, the opening of the packaging bag for dry mortar is placed on the discharge pipe 3, and then the screw conveyor and fan 401 are started. The screw conveyor drives the mortar in the mixing tank 1 into the discharge pipe 2, and then continues to flow into the discharge pipe 3, and finally into the packaging bag. When the dust raised in the packaging bag overflows from the bag opening, the suction effect formed by the fan 401 in the hollow cavity 301 draws the dust away through the dust suction hole 302 and discharges it into the dust collection box 5 through the dust removal pipe 4.
