Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to a device for preparing epoxy mortar. Background Technology

[0002] Epoxy mortar is a high-strength, high-adhesion solidified body made primarily of epoxy resin, combined with accelerators and other additives, and cured. It possesses excellent impermeability, freeze-thaw resistance, salt resistance, alkali resistance, weak acid resistance, corrosion resistance, and repair and reinforcement properties. Therefore, it is widely used in the protection of hydraulic structures' flow surfaces against erosion, cavitation, and freeze-thaw cycles, as well as in the wear protection and repair of highways, bridges, airport runways, workshops, and other engineering projects. In preparing epoxy mortar, toughening agents and diluents are typically added to the flowing epoxy resin to liquefy it, followed by the addition of curing agents, fillers, and aggregates according to the specified proportions, and then rapid and thorough mixing is required.

[0003] A search revealed Chinese patent application number 202120164634.6, which discloses an epoxy mortar mixing device. The device includes a mixing tank with a sealing cover for sealing the tank. A support plate is fixed to the inner surface of the sealing cover. A mixing motor and several cylinders are mounted on the upper surface of the support plate. A mixing roller coaxially connected to the working end of the mixing motor is located below the support plate. Several support rods coaxially connected to the cylinders are also located below the support plate. Several interference flow rings are fixed to the support rods. An air extraction pipe is connected to the sealing cover, and a vacuum pump is connected to the air extraction pipe. The purpose of this invention is to solve the problem of air bubbles easily forming during the mixing of traditional epoxy mortar.

[0004] However, the above-mentioned epoxy mortar mixing device still has the following drawbacks:

[0005] During the mixing process of epoxy mortar, due to the viscosity and fluidity of the mortar, some mortar may adhere to the inner wall of the mixing drum, especially in the corners and edges. These areas are prone to forming mixing dead zones, causing mortar to accumulate in these places and gradually form a thick residual layer. Therefore, we need a building epoxy mortar preparation device to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a building epoxy mortar preparation device. It mainly uses a stirring motor to drive a stirring shaft, which in turn rotates multiple stirring rods to achieve comprehensive mixing of the epoxy mortar. Multiple fixed rods and brushes are installed on the bottom side wall of the stirring shaft. As the stirring shaft rotates, the brushes continuously scrape the inner wall of the mixing tank, especially the corners and edges, effectively removing mortar adhering to these difficult-to-mix areas. This prevents mortar from accumulating in these places and forming a thick residue layer, ensuring the cleanliness of the mixing tank and reducing potential contamination during subsequent use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a building epoxy mortar preparation device, comprising a box body, a discharge port on the surface of the box body, a mixing assembly installed inside the top of the box body, the mixing assembly comprising a mixing motor, a mixing shaft and multiple mixing rods, the base of the mixing motor being installed in the middle of the top of the box body, the output shaft of the mixing motor being connected to one end of the mixing shaft, the other end of the mixing shaft passing through the inner cavity of the box body and rotatably mounted on the inner bottom of the box body, multiple mixing rods being equidistantly installed around the surface of the mixing shaft, multiple fixing rods being installed on the bottom side wall of the mixing shaft, multiple brushes being equidistantly installed on the bottom of the fixing rods, one end of each brush abutting against the bottom of the cavity of the box body, and a discharge assembly being provided below the bottom of the box body.

[0008] Preferably, a plurality of support rods are installed on the top side wall of the stirring shaft. The support rods and the fixing rods are arranged parallel to each other vertically. A scraper is connected to one end of each support rod and one end of each fixing rod. The side wall of the scraper is in close contact with the inner wall of the box.

[0009] Preferably, the sidewall surface of the scraper is provided with a rubber layer, and the brush is a hard brush.

[0010] Preferably, the discharge assembly includes a discharge pipe and a valve, the bottom of the housing has a discharge port, one end of the discharge pipe is connected to the discharge port, and the valve is installed on the surface of the other end of the discharge pipe.

[0011] Preferably, a removable filter screen is installed at the outlet of the discharge pipe, and the filter screen is coated with an anti-oxidation coating.

[0012] Preferably, a cleaning assembly is installed on one side of the top of the housing. The cleaning assembly includes a clean water tank, a water pipe, a water storage tank, and spray nozzles. The clean water tank is installed on one side of the top of the housing. A water pump is installed on one side of the clean water tank. The outlet of the water pump is connected to one end of the water pipe. The other end of the water pipe passes through the top of the housing and is connected to the inside of the water storage tank. The water storage tank is installed in a ring shape at the top of the inner part of the housing. Multiple spray nozzles are installed at the bottom of the water storage tank.

[0013] Preferably, a display screen is installed on the surface of the enclosure, and multiple support columns are installed at the bottom of the enclosure, with a fixing pad fixedly installed at the bottom of each support column.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention mainly uses a stirring motor to drive a stirring shaft, which in turn drives multiple stirring rods to rotate, achieving comprehensive mixing of epoxy mortar. The multiple fixed rods and brushes installed on the bottom side wall of the stirring shaft allow the brushes to continuously scrape the inner wall of the mixing tank as the stirring shaft rotates, especially in corners and edges. This effectively removes mortar adhering to these difficult-to-mix areas, preventing mortar from accumulating in these places and forming a thick residue layer. It also ensures the cleanliness of the mixing tank and reduces potential contamination during the next use. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a building epoxy mortar preparation device, including a box body 1, a discharge port 4 on the surface of the box body 1, a mixing assembly installed inside the top of the box body 1, the mixing assembly including a mixing motor 5, a mixing shaft 51 and multiple mixing rods 52, the base of the mixing motor 5 is installed in the middle of the top of the box body 1, the output shaft of the mixing motor 5 is connected to one end of the mixing shaft 51, the other end of the mixing shaft 51 passes through the inner cavity of the box body 1 and is rotatably installed at the inner bottom of the box body 1, multiple mixing rods 52 are equidistantly installed around the surface of the mixing shaft 51, multiple fixing rods 55 are installed on the bottom side wall of the mixing shaft 51, multiple brushes 56 are equidistantly installed at the bottom of the fixing rods 55, one end of the brushes 56 abuts against the bottom of the cavity of the box body 1, and a discharge assembly is provided below the bottom of the box body 1;

[0023] During use, the stirring motor 5 drives the stirring shaft 51 to rotate multiple stirring rods 52, achieving comprehensive mixing of the epoxy mortar. The multiple fixed rods 55 and brushes 56 installed on the bottom side wall of the stirring shaft 51 are designed so that as the stirring shaft 51 rotates, the brushes 56 can continuously scrape the inner wall of the mixing tank, especially the corners and edges, effectively removing the mortar adhering to these difficult-to-mix areas, preventing the mortar from accumulating in these places and forming a thick residual layer, and also ensuring the cleanliness of the mixing tank and reducing possible contamination during the next use.

[0024] Multiple support rods 53 are installed on the top side wall of the mixing shaft 51. The support rods 53 and the fixed rods 55 are arranged parallel to each other vertically. One end of the support rod 53 and one end of the fixed rod 55 are connected to scrapers 54. The side wall of the scraper 54 is in close contact with the inner wall of the box 1. The design of the scraper 54 makes its side wall fit tightly against the inner wall of the box 1. As the mixing shaft 51 rotates, the scraper 54 can thoroughly scrape the inner wall of the mixing tank, ensuring that all parts of the inner wall of the mixing tank can be thoroughly cleaned, avoiding the residue and accumulation of mortar during the mixing process.

[0025] The scraper 54 has a rubber layer on its side wall surface and the brush 56 is a hard brush. The rubber layer, as a soft material, can play a buffering role during the scraping process, reducing the impact and wear on the inner wall of the box 1. The hard brush has strong hardness and wear resistance, and can more effectively remove mortar residue on the inner wall of the box 1.

[0026] The discharge assembly includes a discharge pipe 7 and a valve 71. A discharge port 73 is provided at the bottom of the inner end of the housing 1. One end of the discharge pipe 7 is connected to the discharge port 73, and the valve 71 is installed on the other end surface of the discharge pipe 7. The direct connection between the discharge pipe 7 and the discharge port 73 reduces the obstruction and resistance of the mortar during the discharge process, allowing the mortar to flow out more smoothly. By adjusting the opening degree of the valve 71, the construction personnel can precisely control the discharge speed of the epoxy mortar, ensuring that the mortar is discharged according to the predetermined flow rate and speed, avoiding waste and overflow.

[0027] A removable filter screen 72 is installed at the outlet of the discharge pipe 7. The filter screen 72 is coated with an anti-oxidation coating. The removable filter screen 72 can effectively intercept impurities in the epoxy mortar. The anti-oxidation coating on the filter screen 72 can effectively resist oxidation and reduce corrosion and aging of the filter screen 72 due to long-term contact with air or chemical components in the mortar.

[0028] A cleaning assembly is installed on one side of the top of the tank 1. The cleaning assembly includes a clean water tank 3, a water pipe 32, a water storage tank 33, and spray nozzles 34. The clean water tank 3 is installed on one side of the top of the tank 1. A water pump 31 is installed on one side of the clean water tank 3. The outlet of the water pump 31 is connected to one end of the water pipe 32. The other end of the water pipe 32 passes through the top of the tank 1 and connects to the inside of the water storage tank 33. The water storage tank 33 is installed in a ring shape at the top inner part of the tank 1. Multiple spray nozzles 34 are installed at the bottom of the water storage tank 33. The ring shape of the water storage tank 33 at the top inner part of the tank 1 ensures that the clean water can fully cover the inner wall of the mixing tank. The multiple spray nozzles 34 are evenly distributed at the bottom of the water storage tank 33, making the cleaning more uniform and thorough and avoiding cleaning dead corners.

[0029] A display screen 2 is installed on the surface of the box 1, and multiple support columns 6 are installed at the bottom of the box 1. A fixing pad 61 is fixedly installed at the bottom of the support column 6. Through the display screen 2, the operator can clearly see the working status of the mixing device, the mortar preparation progress, mixing parameters and other key information. The combined design of the support column 6 and the fixing pad 61 helps to reduce the vibration and noise generated during the mixing process.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
