Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building construction equipment, especially point to a kind of anti-adhesion mortar mixing device. BACKGROUND

[0002] In the field of construction engineering, mortar is the core material for wall building, wall plastering, ground leveling and structure reinforcing and other construction links, and its performance directly affects the quality and durability of construction engineering. The preparation of mortar usually needs to mix cement, sand, water and other components uniformly through a mixing device, and the efficiency and uniformity of the mixing process depend on the structural design and working performance of the mixing device. With the acceleration of building industrialization, higher requirements are put forward for the automation degree, mixing efficiency and reliability of mortar mixing device.

If these adherents are not removed in time, they will gradually harden and form clumps, not only reducing the effective volume of the tank and the uniformity of material mixing, but also increasing the rotating resistance of the stirring paddle, which increases the load of the driving motor, causing the mixing efficiency to decrease and the energy consumption to increase. For example, the traditional mixing device relies on a single stirring paddle blade to scrape the inner wall of the tank, but its adhesion and cleaning range are limited, and it is difficult to completely remove the adherents in the corners and edges. Although some devices are equipped with water spraying cleaning structure, the water flow is unevenly distributed, there are dead angles in the cleaning area, and there is no synergistic effect with the mechanical wall scraping structure, resulting in poor adhesion removal effect. The above defects not only increase the maintenance cost and downtime of the equipment, but also fail to meet the demand of green construction for energy saving and consumption reduction, so a new type of mortar mixing device that can effectively prevent the hardening of adherents and improve the mixing efficiency is needed.

DETAILED DESCRIPTION

[0026] The utility model will be further described in conjunction with the specific embodiments of the drawings, see Figures 1-4 :

[0027] Embodiment 1:

[0028] The embodiment provides a kind of anti-adhesion mortar stirring device, including tank body 1 and the feed hopper 2 of being arranged in the top of tank body 1, still include:

[0029] Stirring paddle 3, be arranged in tank body 1, the stirring paddle 3 includes wall scraping structure 30, for removing adhering object adhered to the inner wall of tank body 1, the bottom of the tank body 1 is equipped with the drive motor 4 for driving stirring paddle 3 rotation;

[0030] Water flow cleaning mechanism 5, including the water supply pipe 50 of being arranged in the top of tank body 1, the water supply pipe 50 has inflow part 51 connected with external water source, several water outlet holes 53 distributed along its length direction, and flow adjusting assembly 6 for controlling the opening and closing number of water outlet hole 53;

[0031] The water flow cleaning mechanism 5 sprays water through the water outlet hole 53 to remove the adhering materials in cooperation with the wall scraping structure 30.

[0032] The tank body 1 serves as a space for mixing mortar and provides a place for mixing materials and bears mechanical forces and material pressure during the mixing process. The tank body 1 is usually a cylindrical structure with an open top for feeding and installing other components. The bottom of the tank body 1 can be connected to the external support structure by welding or bolting to ensure stable placement of the device.

[0033] The feed hopper 2 guides the smooth entry of materials into the tank body 1, serving as a material guide and preliminary buffer. The feed hopper 2 is generally funnel-shaped, wide at the top and narrow at the bottom, with the bottom opening connected to the top opening of the tank body 1. The feed hopper 2 and the top of the tank body 1 can be connected by welding or bolting to ensure tight connection and prevent material leakage.

[0034] The stirring paddle 3 generates mechanical force by rotating to stir and mix the materials in the tank body 1 to achieve uniformity. The stirring paddle 3 includes a connecting shaft connected to the output shaft of the driving motor 4 through a shaft coupling. The driving motor 4 can be fixed on the bottom of the tank body 1 by bolting or welding.

[0035] The wall scraping structure 30 removes the adhering materials adhering to the inner wall of the tank body 1 during the rotation of the stirring paddle 3, preventing the accumulation of adhering materials and affecting the stirring effect and service life of the tank body 1.

[0036] The water flow cleaning mechanism 5 flushes the inner wall of the tank body 1, the stirring paddle 3, and the materials by spraying water, assisting the wall scraping structure 30 in removing adhering materials, and adjusting the moisture content of the materials to some extent, improving the stirring effect.

[0037] The water supply pipe 50 serves as a water flow delivery channel to introduce water from an external water source into the tank body 1 and uniformly spray water into the stirring area through the water outlet hole 53. The water supply pipe 50 is a tubular structure with an internal water flow channel and an external connecting part 52 for connecting to an external water source. The water supply pipe 50 can be fixed on the top of the tank body 1 by external support structure or welding.

[0038] The inflow part 51 serves as the connection interface between the water supply pipe 50 and the external water source, responsible for introducing water flow into the water supply pipe 50. The inflow part 51 is usually an interface with threads or quick plug structure for easy connection with the water pipe of the external water source. The inflow part 51 is connected to the water pipe of the external water source by screwing or quick plug connection to ensure good sealing.

[0039] The water outlet holes 53 spray the water in the water supply pipe 50 into the stirring area in the tank body 1 to clean the material, the stirring paddle 3 and the inner wall of the tank body 1. The water outlet holes 53 are hole structures formed on the wall of the water supply pipe 50 and are distributed along the length direction of the water supply pipe 50, so that the water flow can directly clean the parts of the stirring paddle 3 and the inner wall of the tank body 1 that need to be cleaned.

[0040] The flow regulating assembly 6 controls the opening and closing number of the water outlet holes 53, thereby regulating the water flow of the water supply pipe 50 to adapt to the demand for the amount of cleaning water under different stirring conditions.

[0041] When the driving motor 4 is started, the motor output shaft drives the connecting shaft of the stirring paddle 3 to rotate, so that the stirring paddle 3 rotates at high speed in the tank body 1. The blades on the stirring paddle 3 stir and mix the mortar material in the tank body 1, so that the mortar material gradually reaches a uniform state. During the stirring process, due to the friction between the material and the inner wall of the tank body 1 and the surface of the stirring paddle 3, part of the material will adhere to these parts. At this time, the wall scraping structure 30 rotates with the stirring paddle 3, and the deformable scraper 300 closely contacts the inner wall and the bottom of the tank body 1 to scrape off the material adhered thereto.

[0042] At the same time, the water flow cleaning mechanism 5 starts to work. The water from the external water source enters the water supply pipe 50 through the inflow part 51, and the water in the water supply pipe 50 is sprayed out from each water outlet hole 53 under the action of pressure to clean the stirring paddle 3 and the inner wall of the tank body 1. The water flow directly washes away part of the adhered material, and on the other hand, it assists the wall scraping structure 30 to make the scraped adhered material more easily washed away.

[0043] Embodiment 2:

[0044] The embodiment provides a mortar stirring device capable of preventing material adhesion, which has the following technical features in addition to the technical solutions of the above-mentioned embodiments.

[0045] The inner surface of the tank body 1 and the outer surface of the stirring paddle 3 are coated with a Teflon coating.

[0046] During the stirring of the mortar, the material is prone to adhere to the surfaces of the tank body 1 and the stirring paddle 3 due to factors such as surface tension and friction. The micro concave-convex structure on the surface of the traditional material can exacerbate the retention of the material, and after hardening, it not only increases the cleaning difficulty, but also reduces the stirring efficiency and shortens the service life of the equipment. Coating the inner surface of the tank body 1 and the outer surface of the stirring paddle 3 with a Teflon coating is just to solve this problem. The Teflon coating has extremely low surface energy and self-lubricating properties, which can significantly reduce the adhesion between the material and the surface of the equipment, so that the mortar is difficult to adhere; at the same time, the smooth surface can reduce the retention of the material, and even a small amount of adhesion can be easily separated under the action of the rotation of the stirring paddle 3, the water flow washing or the wall scraping structure 30, thereby reducing the cleaning and maintenance workload, reducing the stirring resistance caused by the accumulation and hardening of the adhered material, improving the stirring efficiency, prolonging the service life of the equipment and realizing the efficient and stable operation of the stirring device.

[0047] Embodiment 3:

[0048] The anti-adhesion mortar mixing device provided in the embodiment comprises the technical solutions of the above embodiments and has the following technical features.

[0049] The top edge of the tank body 1 is designed with a round corner transition to eliminate the risk of adhesion at the corner.

[0050] During the mortar mixing process, the corner structure at the top of the traditional tank body 1 is prone to form a material stagnation point. Under the action of gravity and stirring force, the mortar is easily accumulated at the corner, and after the water evaporates, it hardens to form stubborn adhesion. This not only increases the difficulty of cleaning, but also may mix with the material during subsequent stirring, affecting the quality of the mortar. By designing the top edge of the tank body 1 with a round corner transition, the sharp corners are eliminated, and the contact form of the material with the top edge of the tank body 1 is changed. Under the action of stirring vibration or water flow scouring, the material is difficult to adhere and stay at the top edge, and can more smoothly slide down to the inside of the tank body 1 to participate in stirring or be carried away by the cleaning water flow. This reduces the risk of adhesion from the root cause of the structure design, reduces the frequency of manual cleaning, ensures the efficient operation of the mixing device, and improves the quality of mortar preparation.

[0051] Embodiment 4:

[0052] The anti-adhesion mortar mixing device provided in the embodiment comprises the technical solutions of the above embodiments and has the following technical features.

[0053] The water outlet hole 53 is shaped like a fan and is inclined towards the stirring paddle 3 to form a water curtain covering the stirring area.

[0054] During the cleaning process of the mortar mixing device, if the water dispersed from the water outlet hole 53 is disordered, it is difficult to effectively flush the stirring paddle 3 and the inner wall of the tank body 1, which may result in incomplete cleaning and dead angles. By designing the water outlet hole 53 as a fan shape and inclined towards the stirring paddle 3, the purpose is to fully utilize the cleaning effect of the water flow. The fan-shaped water outlet hole 53 can concentrate the water flow and form a water curtain with a wide and uniform coverage. Compared with the ordinary circular water outlet hole 53, the water flow impact force is more concentrated and the coverage area is larger. The design of being inclined towards the stirring paddle 3 allows the water curtain to accurately cover the stirring area and directly flush each part of the stirring paddle 3 and the inner wall of the tank body 1, especially the areas prone to adhesion of mortar. The adhesion is removed in time, preventing it from adhering again, thereby efficiently removing the adhesion and improving the cleaning effect, ensuring the continuous and efficient operation of the mixing device.

[0055] Embodiment 5:

[0056] The anti-adhesion mortar mixing device provided in the embodiment comprises the technical solutions of the above embodiments and has the following technical features.

[0057] The water supply pipe 50 is a double-path design and is symmetrically arranged at the top of the tank body 1. A connecting part 52 for uniformly distributing water into each water supply pipe 50 is arranged between the inflow part 51 and each water supply pipe 50, so as to balance the water flow distribution and reduce the cleaning dead angle.

[0058] During the cleaning process of the mortar mixing device, if a single-path water supply pipe 50 is used, the water flow distribution is uneven, and the local cleaning of the tank body 1 is not in place, resulting in a cleaning dead angle in some areas, which affects the overall cleaning effect. The water supply pipe 50 is a double-path design and is symmetrically arranged at the top of the tank body 1. A connecting part 52 for uniformly distributing water into each water supply pipe 50 is arranged between the inflow part 51 and each water supply pipe 50, so as to balance the water flow distribution and reduce the cleaning dead angle. The connecting part 52 usually adopts a three-way or four-way pipe fitting or other distribution structure, which is connected to the inflow part 51 at one end and connected to two symmetrically arranged water supply pipes 50 at the other end by welding, threaded connection or flange connection. This connection relationship can uniformly distribute the water flowing from the external water source into the two water supply pipes 50, ensuring that both sides of the top of the tank body 1 can be supplied with sufficient and equal water flow. The symmetrically distributed water supply pipes 50 cooperate with the fan-shaped water outlet holes 53, so that the water curtain can fully cover the mixing area, avoiding the cleaning blind area caused by insufficient or uneven water flow, thereby effectively removing the adhering materials on the inner wall of the tank body 1 and the stirring paddle 3, and improving the cleaning efficiency and overall performance of the mixing device.

[0059] Embodiment 6:

[0060] The present embodiment provides an anti-adhesion mortar mixing device, which further has the following technical features in addition to the technical solutions of the above-mentioned embodiments.

[0061] The flow regulating assembly 6 includes a blocking plate 60 arranged in each water supply pipe 50, and an adjusting screw 61 connected to the blocking plate 60. The adjusting screw 61 drives the blocking plate 60 to move linearly by rotating, so as to control the number of open and closed water outlet holes 53.

[0062] The blocking plate 60 moves in the water supply pipe 50 to block or open the water outlet hole 53, thereby controlling the water flow, which is the core executive component for realizing flow regulation. The blocking plate 60 is usually a flat plate structure matched with the inner diameter of the water supply pipe 50, and the edge is finely processed to ensure the sealing performance and avoid water leakage from the gap between the blocking plate 60 and the pipe wall.

[0063] The adjusting screw 61 converts the rotary motion into the linear movement of the blocking plate 60, and realizes the accurate control of the position of the blocking plate 60 through manual or electric rotary operation. The adjusting screw 61 is a rod-shaped structure with external threads, one end of which is fixedly connected with the blocking plate 60, and the other end extends to the outside of the water supply pipe 50, facilitating the rotation of the operator. The adjusting screw 61 and the blocking plate 60 can be fixed by welding, threading or pin, etc.; and the pipe wall of the water supply pipe 50 is connected through threaded cooperation or sliding sealing.

[0064] Embodiment 7:

[0065] The embodiment provides a kind of anti-adhesion mortar mixing device, in addition to including the technical solutions of above-described embodiment, still have the following technical features.

[0066] The wall scraping structure 30 includes a deformable scraper 300 that conforms to the inner wall and bottom of the tank 1, for adaptive removal of adhering objects.

[0067] The deformable scraper 300, as the core executive component of the wall scraping structure 30, conforms to the complex curved surface of the tank 1 by deforming itself, efficiently removing adhering objects from different shaped inner walls and bottoms. The deformable scraper 300 is a plate-shaped structure that matches the inner wall of the tank 1, directly contacting the inner wall and bottom of the tank 1. When the stirring paddle 3 rotates, the scraper working surface slides along the wall surface of the tank 1. The deformable scraper 300 can be connected to the connecting shaft of the stirring paddle 3 through bolts, clamps or nesting.

[0068] Embodiment 8:

[0069] The embodiment provides a kind of anti-adhesion mortar mixing device, in addition to including the technical solutions of above-described embodiment, still have the following technical features.

[0070] The deformable scraper 300 is made of polyurethane, and has a flow guide groove 301 on the surface.

[0071] Polyurethane is chosen as the material of the deformable scraper 300 because of its good elasticity and wear resistance. When conforming to the complex inner wall curve of the tank 1, the deformable scraper 300 deforms to tightly contact the wall surface, effectively removing adhering objects, and is resistant to long-term scraping without being easily worn. The flow guide groove 301 is provided on the surface of the scraper to work with the water flow cleaning mechanism 5 to achieve better results. When the water flow cleaning mechanism 5 sprays water, the flow guide groove 301 guides the water flow to flow in an orderly manner, forming a directional flushing force to quickly and efficiently wash away the adhering objects scraped off, preventing the accumulation of the scraped objects on the surface of the scraper or their reattachment to the inner wall of the tank 1. In addition, the flow guide groove 301 can enhance the relative movement between the water flow and the surface of the scraper, further reducing the adhesion between the material and the scraper, improving the cleaning efficiency, ensuring the internal cleaning of the mixing device, and thus ensuring the quality of mortar mixing and stable operation of the equipment.

[0072] Embodiment 9:

[0073] The anti-adhesion mortar mixing device provided in the embodiment further has the following technical features in addition to the technical solutions in the above embodiments.

[0074] The stirring paddle 3 further comprises a plurality of stirring blades 31 distributed in a spiral shape, and the surfaces of the stirring blades 31 are provided with raised textures 32 to enhance material tumbling and reduce local adhesion.

[0075] The stirring paddle 3 is provided with a plurality of stirring blades 31 distributed in a spiral shape, which are fixed on the connecting shaft of the stirring paddle 3 by welding, bolt connection or key connection and the like, so as to ensure that the blades are stably connected with the connecting shaft and can reliably transmit torque. Such a design enables the stirring blades 31 to generate a composite stirring force in the axial and radial directions when rotating by utilizing the spiral structure, so as to drive the mortar material to move in a spiral path in a circulating manner, form a strong tumbling and convection effect, and avoid local accumulation of the material, thereby improving the stirring uniformity. The raised textures 32 on the surfaces of the stirring blades 31 can increase the friction between the blades and the material, further strengthen the movement state of the material during stirring, and at the same time, break the adhesion structure of the material on the blade surfaces, reduce the phenomenon of local adhesion of the material to the blade surfaces due to static friction, and enable the material to flow and mix more smoothly between the blades. This not only improves the stirring efficiency, but also reduces the stirring resistance caused by the adhesion of the material, thereby reducing the energy consumption, ensuring stable and efficient operation of the stirring device, and outputting mortar with uniform quality.

[0076] The above embodiments are only preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
