Description

Technical Field

[0001] This application relates to the field of mortar mixing equipment, and in particular to a dust-free premixed mortar mixing device. Background Technology

[0002] In construction, traditional on-site mortar mixing methods generate a large amount of dust due to rudimentary equipment and outdated processes. This dust not only seriously pollutes the air environment at the construction site, affecting the quality of life and health of surrounding residents, but also damages the respiratory system of construction workers. Long-term exposure to high dust environments may lead to occupational diseases such as pneumoconiosis. Therefore, it is necessary to treat the dust generated during the mixing process. With the continuous progress in environmental protection technology, automation technology, and materials science, strong technical support has been provided for the development of dust-free premixed mortar mixing devices.

[0003] Regarding the aforementioned technologies, the inventors believe that existing dust-free premixed mortar mixing devices, during use, suffer from variations in the state and mixing degree of materials at different heights, making it difficult to fully mix materials at different heights. This can easily lead to uneven mixing, with some areas being over-mixed while others are under-mixed, thus affecting the quality stability of the premixed mortar. Utility Model Content

[0009] Optionally, the inner wall cleaning assembly includes a scraper, the outer side of which slides against the inner side wall of the mixing tank, and a connecting rod is provided on the side of the scraper near the turntable. The connecting rod is slidably connected to the scraper and fixedly connected to the turntable.

[0010] Optionally, the scraper has a first groove vertically formed on the side near the connecting rod, and the end of the connecting rod is located in the first groove.

[0011] Optionally, a ring is coaxially arranged inside the mixing tank, and a second groove is coaxially formed on the ring. The end of the scraper extends into the second groove, and the scraper is slidably connected to the ring.

[0012] Optionally, the ring includes an upper ring portion and a lower ring portion disposed opposite to each other, and the second sliding groove includes an upper sliding groove located on the lower surface of the upper ring portion and a lower sliding groove located on the upper surface of the lower ring portion. The scraper is fixedly connected to an upper slider relative to the upper sliding groove, and the upper slider slides inside the upper sliding groove. The scraper is fixedly connected to a lower slider relative to the lower sliding groove, and the lower slider slides inside the lower sliding groove.

[0013] Optionally, a dust guide pipe is fixedly connected to the top wall of the mixing tank. The interior of the dust guide pipe is connected to the interior of the mixing tank.

[0014] Optionally, a feed pipe is fixedly connected to one side of the mixing tank, and a discharge pipe is fixedly connected to the bottom wall of the mixing tank, with a control valve fixedly connected to the discharge pipe.

[0015] Optionally, a feed funnel is fixedly connected to the feed end of the feed pipe.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. By setting a second drive component, when it is necessary to stir the materials, the raw materials to be stirred can be poured into the mixing box through the feed funnel, and then the motor is started. The motor drives the disc to rotate through the rotating shaft. When the disc rotates, the disc will drive the lifting block to rotate on the hollow reciprocating screw through the slide rod. Due to the setting of the hollow reciprocating screw, the lifting block will also rise and fall on the hollow reciprocating screw when rotating, thereby driving the stirring rod to stir while rotating. This enables the materials to achieve a more complex three-dimensional flow in the mixing box, thereby breaking the layering or local agglomeration phenomenon that may form in the stirring process. It allows the material particles of different positions and properties to fully contact, collide and mix, which greatly improves the uniformity of stirring and ensures the stable quality and consistent performance of the premixed mortar.

[0018] 2. By setting up an internal wall cleaning mechanism, when the lifting block rotates and rises, the lifting block will drive the scraper to rotate under the action of the first sliding groove and the connecting rod. When the scraper rotates, the ring and the first sliding groove will limit the scraper as necessary, and the scraper will contact the inner wall of the mixing tank. Therefore, when the scraper rotates, it will stably clean the inner wall of the mixing tank, removing the impurities attached to the inner wall of the mixing tank. The scraper cleans simultaneously during the mixing process, reducing the time and workload of manual cleaning, improving the overall operating efficiency of the equipment, and enabling the equipment to be put into the next mixing production more quickly. The timely removal of impurities by the scraper can effectively prevent scaling and corrosion on the inner wall, extend the service life of the mixing tank, reduce the maintenance cost of the equipment, and ensure the long-term stable operation of the equipment.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] This application discloses a dust-free pre-mixed mortar mixing device. (Refer to...) Figure 1 , Figure 2 A dust-free premixed mortar mixing device includes a mixing tank 1, which has a hollow structure, and a mixing paddle 11 is disposed inside the mixing tank 1. A first drive assembly 2 is disposed inside the mixing tank 1, driving the mixing paddle 11 to move circumferentially within the mixing tank 1 to mix the medium inside the mixing tank 1. A second drive assembly 3 is also disposed inside the mixing tank 1, driving the mixing paddle 11 to move vertically within the mixing tank 1 to mix the medium inside the mixing tank 1. Through the combined action of the first drive assembly 2 and the second drive assembly 3, the mixing paddle 11 achieves a spiral movement and mixing path within the mixing tank 1, improving the mixing effect of the medium inside the mixing tank 1.

[0029] The mixing tank 1 is equipped with an inner wall cleaning component 4. The inner wall cleaning component 4 slides against the inner side wall of the mixing tank 1 and is connected to the first drive component 2. The first drive component 2 drives the inner wall cleaning component 4 to move along the circumferential direction, thereby cleaning the medium on the inner side wall of the mixing tank 1 through the inner wall cleaning component 4.

[0030] Reference Figure 2 , Figure 3 The first drive assembly 2 includes a vertically arranged rotating shaft 21. A support plate 12 is horizontally arranged on the inner side wall of the mixing tank 1 at the top of the rotating shaft 21. The support plate 12 is fixedly connected to the side wall of the mixing tank 1, and the support plate 12 is rotatably connected to the rotating shaft 21. The bottom end of the rotating shaft 21 extends from the bottom wall of the mixing tank 1, and the rotating shaft 21 is rotatably connected to the mixing tank 1. A rotary motor 211 is fixedly connected to the bottom wall of the mixing tank 1 relative to the rotating shaft 21. The motor shaft of the rotary motor 211 is coaxial with and fixedly connected to the rotating shaft 21. The rotary motor 211 drives the rotating shaft 21 to rotate inside the mixing tank 1.

[0031] A turntable 22 is fixedly connected to the side wall of the rotating shaft 21. The turntable 22 is coaxial with the rotating shaft 21, so that the rotating shaft 21 drives the turntable 22 to rotate. Two parallel sliding rods 23 are vertically arranged on the upper surface of the turntable 22, and the sliding rods 23 are arranged symmetrically about the turntable 22.

[0032] Reference Figure 2 , Figure 4 A lifting block 24 is coaxially arranged above the turntable 22. The lifting block 24 has a circular structure, and a sliding rod 23 passes through the side wall of the lifting block 24. The sliding rod 23 is slidably connected to the lifting block 24, and when the turntable 22 drives the sliding rod 23 to rotate, the sliding rod 23 drives the lifting block 24 to rotate synchronously. The outer wall of the lifting block 24 is fixedly connected to the stirring paddle 11, thereby driving the stirring paddle 11 to rotate, and the stirring paddle 11 stirs the medium inside the mixing tank 1.

[0033] The second drive assembly 3 includes a reciprocating screw 31 sleeved on the outside of the rotating shaft 21. The reciprocating screw 31 is coaxially arranged with the rotating shaft 21 and is rotatably connected to the rotating shaft 21. One end of the reciprocating screw 31 abuts against the turntable 22, and the reciprocating screw 31 is rotatably connected to the turntable 22. The other end of the reciprocating screw 31 abuts against the support plate 12, and the reciprocating screw 31 is fixedly connected to the support plate 12.

[0034] The inner wall of the lifting block 24 is threadedly connected to the reciprocating screw 31. Thus, when the lifting block 24 moves up and down, it can drive the lifting block 24 to rotate, thereby driving the stirring paddles 11 located on both sides of the lifting block 24 to rotate and stir the medium located inside the mixing tank 1.

[0035] Reference Figure 2 , Figure 5The inner wall cleaning component 4 includes a ring 41, which is coaxially arranged with the mixing tank 1. The ring 41 includes an upper ring portion 411 and a lower ring portion 412 arranged opposite to each other along the height direction. The upper ring portion 411 is fixedly connected to the mixing tank 1, and the lower ring portion 412 is fixedly connected to the mixing tank 1.

[0036] An upper sliding groove 4111 is coaxially formed on the lower surface of the upper ring portion 411, and a lower sliding groove 4121 is coaxially formed on the upper surface of the lower ring portion 412. A scraper 42 is vertically arranged between the upper ring portion 411 and the lower ring portion 412, with its outer sidewall abutting against and slidingly connected to the inner sidewall of the mixing tank 1. An upper slider is fixedly connected to the top of the scraper 42, and the upper slider is located inside the upper sliding groove 4111 and slidingly connected to it. A lower slider is fixedly connected to the bottom of the scraper 42, and the lower slider is located inside the lower sliding groove 4121 and slidingly connected to it.

[0037] Reference Figure 4 , Figure 5 A connecting rod 43 is horizontally arranged between the opposing scrapers 42. The end of the connecting rod 43 away from the scraper 42 is fixedly connected to the lifting block 24, so that the lifting block 24 drives the scraper 42 to rotate. A first groove 421 is vertically formed on the side of the scraper 42 near the connecting rod 43, and the end of the connecting rod 43 is located inside the first groove 421. Thus, when the lifting block 24 moves along the height direction, it drives the connecting rod 43 to slide vertically inside the first groove 421.

[0038] Reference Figure 1 , Figure 2 A dust guide pipe 5 is fixedly connected to the top wall of the mixing tank 1. A fan is fixedly connected inside the dust guide pipe 5, and the fan blows air towards the side away from the inside of the mixing tank 1. The inside of the dust guide pipe 5 is in relative communication with the inside of the mixing tank 1, and multiple air outlets 51 are opened on the top wall of the dust guide pipe 5, so that the fan discharges the gas inside the mixing tank 1 from the air outlets 51 to the outside for centralized collection and treatment.

[0039] A feed pipe 6 is fixedly connected to the side wall of the mixing tank 1. The feed pipe 6 is in relative communication with the interior of the mixing tank 1, and a feed funnel 61 is coaxially fixedly connected to the top of the feed pipe 6. External materials are injected into the interior of the mixing tank 1 through the feed funnel 61 from the feed pipe 6.

[0040] Reference Figure 2 , Figure 3 A discharge pipe 7 is fixedly connected to the bottom wall of the mixing tank 1, and the interior of the discharge pipe 7 is in relative communication with the interior of the mixing tank 1. A control valve 71 is fixedly connected to the discharge pipe 7, and the control valve 71 is used to control the discharge of the medium inside the mixing tank 1 from the interior of the discharge pipe 7.

[0041] In use, first place the device in the appropriate position, pour the raw materials to be stirred into the mixing tank 1 through the feed funnel 61, and then start the rotating motor 211. The rotating motor 211 drives the turntable 22 to rotate through the rotating shaft 21. When the turntable 22 rotates, it drives the lifting block 24 to rotate on the hollow reciprocating screw 31 through the slide rod 23. Due to the setting of the reciprocating screw 31, the lifting block 24 will also rise and fall on the reciprocating screw 31 when it rotates, thereby driving the stirring paddle 11 to stir while rotating. When the lifting block 24 rotates and rises and falls, the lifting block 24 will be in the first slide groove 421 and the connecting rod 43. The scraper 42 is driven to rotate under the action. When the scraper 42 rotates, the ring 41 and the first sliding groove 421 will limit the scraper 42 as necessary, and the scraper 42 will contact the inner wall of the mixing box 1. Therefore, when the scraper 42 rotates, it will stably clean the inner wall of the mixing box 1 and remove the impurities attached to the inner wall of the mixing box 1. If dust removal is required when the material is being mixed, the fan can be started to suck the dust in the mixing box 1 to the outside of the device through the dust guide pipe 5 and collect it. After the mixing is completed, the control valve 71 can be opened to discharge the mixed material in the mixing box 1 through the discharge pipe 7.
