Description

Technical Field

[0001] This invention relates to the field of lightweight concrete processing, and more particularly to an automated production system for red mud foam lightweight concrete. Background Technology

[0002] Foamed concrete, also known as lightweight concrete, is a new type of lightweight thermal insulation material containing a large number of closed pores. It is produced by mechanically foaming a foaming agent using a foaming machine's foaming system, uniformly mixing the foam with cement slurry, and then pouring it in place or molding it using the foaming machine's pumping system. After natural curing, it becomes a new type of building material. Lightweight foamed concrete blocks are a new type of building material that is lightweight, porous, has good thermal insulation properties, good fire resistance, can be nailed, sawed, and planed, and has a certain degree of earthquake resistance.

[0003] Currently, during the processing of red mud lightweight foamed concrete, there are technical problems such as uneven and insufficient mixing of raw materials, concrete sticking and clumping on the inner wall of the mixing drum, making it impossible to scrape off, manual scraping being time-consuming and labor-intensive, and the corrosive nature of red mud causing corrosion to the equipment. To address these issues, an automated production system for red mud foamed lightweight concrete has been proposed. Summary of the Invention

[0004] To address the technical problems of uneven and insufficient mixing of raw materials, concrete sticking and clumping on the inner wall of the mixing drum making it impossible to scrape off, the time-consuming and labor-intensive nature of manual scraping, and the corrosive nature of red mud causing corrosion to the equipment.

[0005] This invention is achieved using the following technical solution: an automated production system for red mud foam lightweight concrete, characterized in that it includes a base, a top cover, a mixing drum, a mixing assembly, a feeding assembly, and a cleaning assembly;

[0006] The base is fixed to the outside, and a hydraulic lifting rod is also installed on the base. The output end of the hydraulic lifting rod is connected to the mounting base plate.

[0007] The mixing drum is mounted on the mounting base plate. The mixing drum includes an inner drum and an outer drum, with a sandwich layer between the inner drum and the outer drum. The bottom of the outer drum is provided with a discharge port, and a feeding auxiliary component is installed at the discharge port. A fixing component for installing the inner drum is also installed in the sandwich layer.

[0008] The top cover is fastened onto the outer cylinder, and a feed hopper and a feed pipe are also installed on the top cover. The feed hopper and feed pipe are used to input raw materials and foam, respectively.

[0009] The stirring assembly includes a first motor, a stirring shaft, stirring blades, a telescopic mounting tube, and a second motor. The first motor is mounted on the top cover, and its output end is connected to the stirring shaft. The stirring shaft is coaxially arranged in the inner cylinder, and two telescopic mounting tubes are symmetrically installed on both the upper and lower sides of the stirring shaft. The other end of the telescopic mounting tube is equipped with stirring blades, one side of which contacts the inner wall of the inner cylinder. The second motor is installed at the bottom of the interlayer, and its output end is used to drive the inner cylinder to rotate.

[0010] The feeding assembly includes a feeding hopper, a feeding gate, and a quick-connect pipe. The feeding hopper is installed at the bottom of the outer cylinder, the feeding gate is installed at the bottom of the feeding hopper, and the quick-connect pipe is installed at the bottom of the feeding gate. The quick-connect pipe is connected to the pump.

[0011] A cleaning assembly is also installed on the mounting base plate;

[0012] In the above scheme, the bottom of the feeding hopper and the feeding pipe both extend into the inner cylinder, and the diameter of the feeding pipe is larger than the diameter of the foaming machine's outlet. By extending the bottom of the feeding hopper and the feeding pipe into the inner cylinder, it can be ensured that no raw materials are wasted or missed during feeding. By setting the diameter of the feeding pipe to be larger than the diameter of the foaming machine's outlet, it is beneficial for the foaming machine to directly inject foam into the inner cylinder.

[0013] As a further improvement to the above solution, the bottom outlet of the inner cylinder is semi-open, and a baffle is installed at the outlet. The baffle is slidably connected to the bottom of the inner cylinder. A groove is also provided at the bottom of the inner cylinder, and a slider is provided in the groove. The slider is connected to the baffle. By installing a baffle at the bottom of the inner cylinder, it is possible to ensure that the inner cylinder is sealed during stirring and facilitate material discharge.

[0014] As a further improvement to the above solution, the fixing component includes two ring hoops, which are symmetrically installed in the interlayer along the vertical direction. Each ring hoop is also provided with a sliding groove, in which a number of sliders are installed. The sliders are circumferentially distributed in the sliding groove. The motor drives the sliders to slide. By setting the ring hoops, it can be ensured that the inner cylinder can be installed inside the outer cylinder. By setting the sliding grooves on the ring hoops and installing the sliders, it can be ensured that the inner cylinder can rotate independently of the outer cylinder during installation.

[0015] As a further improvement to the above solution, the stirring blades are installed at an angle at the other end of the telescopic mounting pipe, and the shape of the stirring blades is set to arc. By setting the stirring blades to an arc shape, it is advantageous for them to fit against the inner wall of the inner cylinder when scraping and cleaning the inner wall.

[0016] As a further improvement to the above solution, the working directions of motor one and motor two are opposite. The output end of motor two drives the inner cylinder to rotate through a belt. By setting the working directions of motor one and motor two in opposite directions, it can be ensured that motor two drives the inner cylinder to rotate independently of the outer cylinder, thereby fully mixing the raw materials.

[0017] As a further improvement to the above solution, the cleaning assembly includes a water tank, water pipes, an annular hollow tube, a telescopic tube, and a nozzle. The water tank is mounted on the mounting base plate, and the inlet end of the water tank is connected to the outside. The outlet end of the water tank is connected to a water pump. One end of the water pipe is connected to the water pump, and the other end is connected to the inside of the annular hollow tube. The annular hollow tube is mounted on the outer frame. The telescopic water pipes are circumferentially distributed on the ring, and the telescopic tubes are connected to the inside of the annular hollow tube. The nozzle is mounted on the top of the telescopic tube. By connecting the inner wall of the annular hollow tube and the telescopic tube, it can be ensured that during stirring, the water can pass through the annular hollow tube and the telescopic tube, spray out from the nozzle, and finally flow into the inner cylinder. During scraping and cleaning, the water pressure is increased by the water pump, thereby effectively cleaning and scraping the inner wall of the inner cylinder, thus ensuring that the red mud will not corrode the equipment.

[0018] As a further improvement to the above solution, sealing strips are provided at the connection points of the water pipe and the water tank, the water pipe and the annular hollow pipe, and the telescopic pipe and the annular hollow pipe. By using sealing strips at the connection points, it can be ensured that the equipment will not leak water during operation, thereby ensuring the personal safety of the staff.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] By designing the mixing drum as a two-layer structure, consisting of an outer drum and an inner drum, the inner drum can rotate independently of the outer drum. Simultaneously, a motor mounted on the top cover drives the mixing shaft and the mixing blades on the shaft, enabling uniform and effective mixing of raw materials. A telescopic mounting pipe is installed on the mixing shaft, with mixing blades at the other end. This allows the mixing blades to not only mix the raw materials but also, after pouring, extend the telescopic mounting pipe to bring the mixing blades into contact with the inner wall of the drum, effectively scraping away any concrete adhering to the inner wall. A water pump in the water tank provides water for mixing and, during scraping and cleaning, increases the water pressure while extending the telescopic mounting pipe to bring the mixing blades into contact with the inner wall of the drum. The combined action of the mixing blades and water flow effectively washes the inner wall of the drum. A baffle and a discharge auxiliary component at the bottom of the inner drum not only seal the drum during mixing to prevent material leakage but also, during discharge, accelerate the unloading process by coordinating the discharge auxiliary component with the motor-driven mixing blades.

By setting the diameter of the feeding pipe 22 to be larger than the diameter of the foaming machine's outlet, it is beneficial for the foaming machine to directly inject foam into the inner cylinder 31.

[0041] As an optional embodiment of the present invention, the bottom outlet of the inner cylinder 31 is semi-open, and a baffle 63 is also installed at the outlet.

[0045] In an optional embodiment of the present invention, the cleaning assembly includes a water tank 8, a water pipe 81, an annular hollow pipe 82, a telescopic pipe 83, and a nozzle 84. The water tank 8 is mounted on the mounting base plate 12, and the inlet end of the water tank 8 is connected to the outside. The outlet end of the water tank 8 is connected to a water pump.

[0047] Working principle:

[0048] Raw materials are poured into the inner cylinder 31 through the feed hopper 21 installed on the top cover 2; then, the motor 4 installed on the top cover 2 drives the stirring shaft 41 inside the inner cylinder 31 to rotate, thereby driving the stirring blades 42 at the other end of the telescopic mounting pipe 43 installed on the stirring shaft 41 to rotate, thus stirring the raw materials. When the motor 4 on the top cover 2 starts working, the water pump also starts working simultaneously, and water flows out from the water tank 8, then flows through the water pipe 81 and the annular hollow pipe 82 into the telescopic pipe 83, and finally flows out from the ring hoop 7 installed above it. The foam is sprayed from the nozzle 84 at the top of the telescopic tube 83; then, the second motor 44 installed at the bottom of the interlayer starts to work, and the second motor 44 rotates through the belt inner cylinder 31 and the raw material inside the inner cylinder 31 (and the working direction of the first motor 4 installed on the top cover 2 is opposite to that of the second motor 44 installed below the interlayer); after the two motors have worked for a period of time and the raw material has been fully stirred, it is inserted into the inner cylinder 31 through the discharge pipe of the foaming machine and the feed pipe 22, and the foaming machine is started to inject foam into the inner cylinder 31; then, the two motors... The machine continues to operate, mixing the newly added foam with the already mixed raw materials. Once mixing is complete, the concrete pump's inlet pipe is connected to the quick-connect pipe 52. Then, the electric telescopic rod 61 installed at the bottom of the inner cylinder 31 begins operation. By shortening the electric telescopic rod 61, the push plate 62 is activated, which in turn activates the baffle 63, thus discharging the material. Simultaneously, the motor 4 installed on the top cover 2 is turned on, driving the mixing blades 42 to push the mixed slurry from the inner cylinder 31 into the discharge hopper 5. The discharge gate 51 located below the discharge hopper 5 is opened, and concrete slurry flows from the discharge hopper 5 into the concrete pump through the pipeline, where it is then poured on-site. After pouring, the electric telescopic rod 61 is extended, driving the push plate 62 to work, which in turn drives the baffle 63 to work, sealing the inner cylinder 31. Then, the telescopic installation pipe 43 is extended, thus bringing the mixing blades 42 into contact with the inner wall of the inner cylinder 31. Subsequently, the two motors and the water pump are turned on, and the water in the water tank is pressurized by the water pump to clean and scrape the inner wall of the inner cylinder 31.

Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
