Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically a dry mortar mixing tank with a dust suppression device. Background Technology

[0002] Dry-mixed mortar refers to a granular or powdery material that is physically mixed in a certain proportion with aggregates (such as quartz sand), inorganic cementitious materials (such as cement), and additives (such as polymers) that have undergone 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.

[0003] Patent publication number "CN213137251U" discloses "A dry-mixed mortar mixing tank with a dust suppression device, which relates to the technical field of dry-mixed mortar production. It solves the problem that when a large amount of raw material falls into the mixing tank from the buffer hopper, due to pressure balance, a large amount of gas will escape upwards from the connection between the mixing tank and the buffer hopper." The tank includes a tank body, a hopper fixedly connected to the tank body, an exhaust box fixedly connected to the hopper, several exhaust holes on the inner circumference of the exhaust box, an exhaust pipe fixedly connected to the exhaust box, a connecting pipe fixedly connected to the top of the tank body, and the end of the connecting pipe away from the tank body connected to the end of the exhaust pipe away from the exhaust box. An exhaust fan is horizontally installed above the tank body, and an air intake assembly is provided between the exhaust fan's air inlet and the connecting pipe. The air intake assembly includes an exhaust pipe, and a filter screen is installed inside the exhaust pipe at the end away from the exhaust fan. It has the advantage of minimizing dust overflow from the hopper when material is discharged from the buffer hopper to the hopper on the mixing tank.

[0004] Although the aforementioned patent can adsorb the dust generated during the feeding process and prevent the dust from floating around, in the initial stage of solid mortar mixing, as water is gradually introduced into the mortar, a large amount of dust will be generated inside the solid mortar under the action of stirring. This dust will be quickly discharged from bottom to top after feeding. It is difficult to clean the dust generated in the initial stage of mixing by simply vacuuming, resulting in incomplete overall dust removal.

[0005] To address this issue, the present invention provides a dry mortar mixing tank with a dust suppression device. Utility Model Content

[0010] Preferably, the conveying pipe is fixedly installed at the top of the upper half of the rotary joint, and the rotating pipe is fixedly installed at the bottom of the lower half of the rotary joint.

[0011] Preferably, a motor is fixedly installed on the top of the mixing tank, a first gear is fixedly installed on the top of the motor, and a second gear is fixedly installed on the outer side of the lower half of the rotary joint, with the first gear and the second gear meshing with each other.

[0014] Beneficial effects

[0015] This invention provides a dry-mixed mortar mixing tank with a dust suppression device. Compared with the prior art, it has the following advantages:

[0016] 1. This dry mortar mixing tank with a dust suppression device organically combines mixing and dust suppression functions. Water enters the rotating pipe through the conveying pipe and rotary joint, and then sprays out from the drain outlet at the bottom of the rotating plate to form a water curtain. While mixing mortar and water, it effectively prevents the dust generated during mixing from floating upwards and avoids dust from being discharged from the feeding inlet. Compared with traditional mixing tanks, it improves the dust removal effect in the initial stage of mixing, ensures a clean working environment, and reduces dust pollution.

[0017] 2. The dry mortar mixing tank with dust suppression device is equipped with a dust removal structure consisting of a side cover, a collection cover, and an air suction pipe. When the material is put into the feeding hopper, the air suction pipe connected to the external industrial vacuum cleaner forms a strong suction in the collection cover, which can quickly gather and absorb the dust generated during the feeding process, reduce the dust dispersion in the feeding process, effectively improve the working environment of operators, and reduce the harm of dust to human health.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0026] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Reference Figures 1 to 5 This application provides a dry mortar mixing tank with a dust suppression device, including a mixing box 1. A feeding component 2 is provided on the top of the mixing box 1, a mixing component 3 is provided inside the mixing box 1, a discharge port 4 is fixedly installed at the bottom of the mixing box 1, and a support leg 5 is fixedly installed at the bottom of the mixing box 1. The mixing component 3 includes a mixing rod 31, a mixing blade 32 is fixedly installed on the outer side of the mixing rod 31, a rotating block 33 is fixedly installed on the top of the mixing rod 31, a rotating pipe 34 is fixedly installed on the top of the rotating block 33, the rotating pipe 34 is rotatably connected to the inner top of the mixing box 1, a rotating plate 35 is fixedly installed on the outer side of the rotating block 33, the rotating block 33 and the rotating plate 35 are hollow inside, the rotating pipe 34 communicates with the inside of the rotating block 33, the rotating block 33 communicates with the inside of the rotating plate 35, and a drain port 36 is opened at the bottom of the rotating plate 35, which connects the inside of the rotating plate 35 to the outside.

[0028] A discharge port 4 is fixedly installed at the bottom of the mixing tank 1, and a support leg 5 is fixedly installed on the outer side of the bottom of the mixing tank 1. A rotary joint 37 is fixedly installed at the top of the rotating pipe 34, and a conveying pipe 38 is fixedly installed at the top of the rotary joint 37. The rotary joint 37 is divided into upper and lower sections, which are rotatably connected to each other. The conveying pipe 38 communicates with the interior of the rotating pipe 34 through the rotary joint 37. A bracket 39 is fixedly installed between the outer side of the upper half of the rotary joint 37 and the mixing tank 1. The conveying pipe 38 is fixedly installed at the top of the upper half of the rotary joint 37, and the rotating pipe 34 is fixedly installed at the bottom of the lower half of the rotary joint 37. A motor 310 is fixedly installed at the top of the mixing tank 1, and a first gear 311 is fixedly installed at the top of the motor 310. A second gear 312 is fixedly installed on the outer side of the lower half of the rotary joint 37, and the first gear 311 and the second gear 312 mesh with each other.

[0029] In this embodiment, the conveying pipe 38 is connected to an external water supply pipe. Water used for mixing mortar enters the rotating pipe 34 through the conveying pipe 38 and the rotary joint 37, and then sprays out from the drain outlet 36 through the rotating block 33 and the rotating plate 35. Fine water jets are sprayed out through multiple drain outlets 36. During the mixing process of water and mortar, the starting motor 310 drives the first gear 311 to rotate, which in turn drives the second gear 312 to rotate. The rotation of the second gear 312 drives the lower half of the rotary joint 37 to rotate and drive the interior of the rotating pipe 34 below. This method ensures that the rotation of the rotating pipe 34 does not affect the conveying pipe 38. The water inside the rotating pipe 34 is transported, and the rotating pipe 34 drives the rotating block 33 to rotate. The rotating block 33 drives the rotating plate 35 and the stirring rod 31 below to rotate. The rotating rod 31 drives the stirring blade 32 to rotate, thereby mixing the mortar and water. The rotation of the rotating plate 35 can form a water curtain composed of rotating fine water columns above the mixed mortar, ensuring water supply while preventing dust generated by the mixing below from floating upwards. This ensures that the dust generated in the initial stage of mixing will not be discharged from the material inlet, thus ensuring a better and more comprehensive dust removal effect. After the mixing is completed, the mortar is discharged by opening the discharge port 4.

[0030] Reference Figures 1 to 5 In one aspect of this embodiment, the feeding assembly 2 includes a feeding hopper 21, which is fixedly installed on the top of the mixing tank 1 and communicates with the interior of the mixing tank 1. A side cover 22 is fixedly installed on the top of the feeding hopper 21, and a collection cover 23 is fixedly installed on the top of the side cover 22. A feeding port is provided on the side of the side cover 22. An air suction pipe 24 is fixedly installed on the top of the collection cover 23 and communicates with the interior of the collection cover 23. A horizontal plate 25 is fixedly installed on the outer side of the air suction pipe 24, and a vertical rod 26 is fixedly installed between the horizontal plate 25 and the top of the mixing tank 1.

[0031] In this embodiment, during feeding, the material is fed into the feeding hopper 21 through the feeding port on the side cover 22. During feeding, the suction pipe 24 is connected to an external high-power industrial vacuum cleaner. By starting the industrial vacuum cleaner, a large suction force is generated inside the collection cover 23 through the suction pipe 24. The suction force can gather the dust generated during the feeding process through the collection cover 23 and absorb it into the industrial vacuum cleaner through the suction pipe 24 for dust removal. In this way, the dust generated during the feeding process is greatly reduced.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] Working principle: The conveying pipe 38 is connected to an external water supply pipe. Water used for mixing mortar enters the rotating pipe 34 through the conveying pipe 38 and the rotary joint 37, and then sprays out from the drain outlet 36 through the rotating block 33 and the rotating plate 35. Fine water jets are sprayed out through multiple drain outlets 36. During the mixing process of water and mortar, the starting motor 310 drives the first gear 311 to rotate, which in turn drives the second gear 312 to rotate. The rotation of the second gear 312 drives the lower half of the rotary joint 37 to rotate and drive the interior of the rotating pipe 34 below. This method ensures that the rotation of the rotating pipe 34 does not affect the delivery of water in the conveying pipe 38 and the rotating pipe 34. The rotating pipe 34 drives the rotating block 33 to rotate, which in turn drives the rotating plate 35 and the stirring rod 31 below to rotate. The rotation of the stirring rod 31 drives the stirring blade 32 to rotate, thereby achieving the mixing of mortar and water. The mixing process, along with the rotation of the rotating plate 35, creates a water curtain composed of rotating fine water columns above the mixed mortar. This ensures water supply while preventing dust generated during mixing from rising upwards, thus preventing dust generated in the initial mixing stage from being discharged from the feeding inlet. This results in a better and more comprehensive dust removal effect. After mixing, the mortar is discharged through the opening of the discharge port 4. During feeding, the material is fed into the feeding hopper 21 through the feeding port on the side cover 22. During feeding, the suction pipe 24 is connected to an external high-power industrial vacuum cleaner. By starting the industrial vacuum cleaner, a large suction force is generated inside the collection cover 23 through the suction pipe 24. This suction force can gather the dust generated during the feeding process through the collection cover 23 and absorb it into the industrial vacuum cleaner through the suction pipe 24 for dust removal. This method greatly reduces the dust generated during the feeding process.
