Abstract

This invention discloses a premixing device for concrete production and processing, relating to the field of concrete production and processing technology. The invention includes a fixed frame, a mixing hopper installed within the frame, a mixing device installed inside the mixing hopper, a control disc fixedly mounted on the surface of the mixing shaft, and an arc-shaped plate movably installed in the top of the mixing hopper. The control disc is rotatably installed inside the mixing hopper. The control disc drives the arc-shaped plate to rotate, causing a discharge hole in the arc-shaped plate to connect with a second inlet. Steel fibers conveyed in the second discharge channel are then added to the mixing hopper through a second funnel.

This cycle repeats, evenly adding the required steel fibers to the mixing hopper and mixing them with other materials.

Description

Technical Field

[0001] This invention relates to the field of concrete production and processing technology, specifically to a premixing equipment for concrete production and processing. Background Technology

[0002] Concrete is one of the most important civil engineering materials in modern times. It is an artificial stone material made by mixing cementitious materials, granular aggregates (also known as aggregates), water, and, when necessary, admixtures and additives in a certain proportion, uniformly mixing, compacting, and curing. Concrete has the advantages of abundant raw materials, low price, and simple production process, which makes its use increasingly larger. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. As the requirements for concrete become higher and higher, some concrete needs to be made by adding fine steel fibers during production and processing to create steel fiber reinforced concrete with higher hardness for use.

[0003] However, in existing steel fiber reinforced concrete processing, the steel fibers are directly added to the mixing tank all at once and mixed with other materials. This method of adding materials cannot ensure that the steel fibers are fully mixed with the other materials. Moreover, in order to ensure that the steel fibers are evenly distributed, a lot of time is required to stir the mixed materials, resulting in a long mixing time and low production efficiency of steel fiber reinforced concrete. Secondly, when conveying materials through pipelines, some materials tend to stick to the inner wall of the pipeline during the material handling process, causing blockages. If not cleaned in time, they can easily stick to the inner wall of the pipeline. In order to address the above problems, the inventor proposes a premixing equipment for concrete production and processing to solve the above problems. Summary of the Invention

[0004] To address the problems of existing steel fiber reinforced concrete processing methods, which involve directly adding the required steel fibers into the mixing tank all at once, failing to ensure thorough mixing of the steel fibers with other materials, and requiring significant time for stirring to achieve uniform fiber distribution, resulting in prolonged mixing time and low production efficiency, the present invention aims to provide a premixing device for concrete production and processing.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a premixing equipment for concrete production and processing, including a fixed frame, a mixing bucket installed in the fixed frame, a stirring device installed in the mixing bucket, the stirring device including a motor, a stirring shaft fixedly installed at the output end of the motor, a control disc fixedly sleeved on the surface of the stirring shaft, an arc plate movably installed in the top of the mixing bucket, the control disc rotatably installed in the mixing bucket, the control disc and the arc plate cooperating with each other, a movable groove is opened on one side of the control disc, first return springs are symmetrically installed in the movable groove, elastic buckles are fixedly connected to the ends of the two first return springs, a positioning groove is opened on one side of the arc plate, the elastic buckles are locked in the positioning groove by the first return springs, a discharge through hole is opened in the top surface of the arc plate, a first feed inlet and a second feed inlet are respectively opened in the top surface of the mixing bucket, the discharge through hole and the second feed inlet cooperating with each other;

[0006] The steel fiber reinforced concrete (excluding steel fibers) is fed into the mixing tank through the first inlet on the top surface of the mixing tank, and the steel fibers to be added are fed into the mixing tank through the second inlet. After the materials enter the mixing tank, the motor switch inside the mixing device is turned on, and the motor output drives the mixing shaft to rotate. The mixing device stirs the materials entering the mixing tank. At the same time, the rotating shaft drives the control panel to rotate. After the control panel rotates to a certain position, the elastic buckles installed in the movable slot by two first return springs are inserted into the positioning slot opened on one side of the arc plate. The control panel drives the arc plate to rotate in the rotating slot, so that the discharge through hole opened in the arc plate is connected to the second inlet. The steel fibers conveyed in the second discharge channel are added into the mixing tank through the second funnel. When the elastic buckles installed in the control panel disengage from the positioning slot opened in the arc plate due to rotation, the second return springs installed in the two mounting slots drive the arc plate to return to its original position, and the steel fibers stop being fed. This cycle is repeated until the materials to be mixed in the steel fiber reinforced concrete are completely mixed.

[0007] Preferably, a mounting frame is fixedly installed on the top surface of the fixed frame. A first fixing groove and a second fixing groove are respectively opened in the top surface of the mounting frame. A first spring is fixedly installed on both sides of the first fixing groove, and one end of the first spring is fixedly connected to a first discharge channel. A second spring is fixedly installed on both sides of the second fixing groove, and one end of the second spring is fixedly connected to a second discharge channel. A connecting plate is fixedly connected to the side adjacent to the first discharge channel and the second discharge channel. A vibrator is installed on the top surface of the connecting plate. The first discharge channel and the second discharge channel are installed and fixed through the first fixing groove and the second fixing groove. When the steel fiber concrete material is conveyed through the first discharge channel and the second discharge channel, the switch of the vibrator installed on the top surface of the connecting plate is turned on. With the cooperation of multiple first springs and multiple second springs, the vibrator drives the first discharge channel, the second discharge channel, the first funnel and the second funnel to vibrate, which solves the problem of pipe blockage during material discharge and the problem of conveyed material sticking to the inner wall of the pipe and being difficult to clean.

[0008] Preferably, the surface of the stirring shaft is symmetrically equipped with fixing members at the bottom of the control panel. Two fixing members have evenly distributed connecting rods fixedly installed on their surfaces. A fixing rod is fixedly connected inside each of the two connecting rods. Evenly distributed fixing rings are fixedly installed on the surface of each fixing rod, and evenly distributed stirring rods are fixedly installed on the surface of each fixing ring. There are two fixing members, and each fixing member has three connecting rods fixedly installed on its surface. The fixing rods are installed and fixed through the two corresponding connecting rods. Multiple fixing rings are fixedly installed on the surface of each fixing rod, and the three stirring rods are installed and fixed through these fixing rings. The multiple stirring rods... The materials in the mixing tank are mixed and stirred. A first funnel is fixedly connected to the bottom surface of the first discharge channel. The bottom end of the first funnel is located inside the first feed inlet. The first funnel and the first feed inlet cooperate with each other. The materials entering the first discharge channel enter the mixing tank through the first funnel and the first feed inlet to mix with the steel fibers. A second funnel is fixedly connected to the bottom surface of the second discharge channel. The bottom end of the second funnel is located inside the second feed inlet. The second funnel, the second feed inlet, and the discharge through-hole cooperate with each other. The steel fibers entering the second discharge channel enter the mixing tank through the second funnel and the second feed inlet to mix with other materials.

[0009] Preferably, a rotating groove is provided on one side of the control panel at the top of the mixing tank. An arc-shaped plate is rotatably installed in the rotating groove via the control panel. The rotating groove assists the arc-shaped plate in rotating, so that the discharge through hole in the arc-shaped plate is connected to the second feed port. A mounting groove is symmetrically provided on one side of the rotating groove at the top of the mixing tank. The mounting groove is connected to the rotating groove. A second return spring is fixedly installed in the two rotating grooves. One end of the second return spring is fixedly connected to the arc-shaped plate. The two mounting grooves assist the arc-shaped plate in rotating. When the elastic buckle installed in one side of the control panel disengages from the positioning groove, the second return spring installed in the two mounting grooves drives the arc-shaped plate to return to its original position.

[0010] Preferably, a discharge pipe is installed on the bottom surface of the mixing drum, and a discharge valve is installed on the surface of the discharge pipe. The discharge pipe and the discharge valve cooperate with each other. After the concrete in the mixing drum is mixed by the mixing device, the discharge valve is opened to discharge the mixed concrete through the discharge pipe. A rotating component is sleeved on the surface of the mixing shaft above the control panel. The rotating component is fixedly installed inside the mixing drum. The rotating component cooperates with the mixing shaft. The rotating component assists the mixing shaft to rotate, thereby driving the control panel to rotate. A fixing plate is fixedly installed in the middle of the fixing frame. The mixing drum is installed inside the fixing frame through the fixing plate. The fixing plate and the fixing frame are used to install and fix the mixing drum.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. In this invention, when the material entering the mixing tank is stirred by the stirring device, the stirring shaft drives the control disc to rotate. The elastic buckle installed on one side of the movable groove cooperates with the positioning groove opened on one side of the arc plate to drive the arc plate to rotate, so that the material discharge hole opened in the arc plate is connected with the second feed port, and the steel fiber conveyed in the second discharge channel is added into the mixing tank through the second funnel. When the elastic buckle installed on one side of the control disc disengages from the positioning groove opened on one side of the arc plate due to rotation in the rotating groove, the second reset spring installed in the two mounting grooves drives the arc plate to reset, and the steel fiber stops feeding. This cycle is repeated until the materials to be mixed in the steel fiber concrete are mixed. Through the above operation, the steel fiber to be added can be evenly added into the mixing tank and mixed with other materials. This not only solves the problem of uneven mixing caused by adding steel fiber at once, but also solves the problem of low mixing efficiency of steel fiber concrete materials.

[0013] 2. In this invention, when the steel fiber concrete material is conveyed through the first discharge channel and the second discharge channel, the switch of the vibrator installed on the top surface of the connecting plate is turned on. With the cooperation of multiple first springs and multiple second springs, the vibrator drives the first discharge channel, the second discharge channel, the first funnel and the second funnel to vibrate, which solves the problem of pipe blockage during material discharge and the problem of conveyed material sticking to the inner wall of the pipe and being difficult to clean.

This allows the steel fibers conveyed in the second discharge channel 5 to be added into the mixing tank 2 through the second funnel 51. When the elastic buckle 82 installed on one side of the control panel 8 disengages from the positioning groove 92 on one side of the arc plate 9 due to rotation, the arc plate 9 is reset by the second return spring 93 installed in the two mounting grooves 26, stopping the steel fiber discharge.

[0034] By adopting the above technical solution, the steel fibers entering the second discharge channel 5 enter the mixing tank 2 through the second funnel 51 and the second feed port 24 to be mixed with other materials.

[0035] A rotating groove 25 is provided on one side of the control panel 8 at the top of the mixing tank 2, and the arc plate 9 is rotatably installed in the rotating groove 25 via the control panel 8;

[0036] By adopting the above technical solution, the rotating groove 25 assists the arc plate 9 to rotate, so that the material discharge through hole 91 opened in the arc plate 9 is connected to the second feed port 24.

[0037] The top of the mixing tank 2 is symmetrically provided with mounting grooves 26 on one side of the rotating groove 25. The mounting grooves 26 and the rotating groove 25 are interconnected.

[0039] A discharge pipe 21 is installed on the bottom surface of the mixing tank 2, and a discharge valve 22 is installed on the surface of the discharge pipe 21. The discharge pipe 21 and the discharge valve 22 cooperate with each other.

[0040] By adopting the above technical solution, after the concrete in the mixing bucket 2 is mixed by the mixing device 7, the discharge valve 22 is opened and the mixed concrete is discharged through the discharge pipe 21.

[0042] By adopting the above technical solution, the rotating part 78 assists the stirring shaft 72 to rotate, thereby driving the control disk 8 to rotate.

[0043] A fixing plate 11 is fixedly installed in the middle of the fixing frame 1, and the mixing bucket 2 is installed inside the fixing frame 1 through the fixing plate 11;

[0044] By adopting the above technical solution, the mixing tank 2 is installed and fixed by the fixing plate 11 and the fixing frame 1.

[0045] Working principle: When steel fiber reinforced concrete needs to be mixed, the steel fiber reinforced concrete material (excluding steel fibers) is fed into the mixing tank 2 through the first feed port 23 on the top surface, and the steel fibers to be added are fed into the mixing tank 2 through the second feed port 24. After the material enters the mixing tank 2, the switch of the motor 71 in the mixing device 7 is turned on. The output end of the motor 71 drives the mixing shaft 72 to rotate, and the mixing device 7 mixes the material entering the mixing tank 2. At the same time, the rotation of the mixing shaft 72 drives the control panel 8 to rotate. After the control panel 8 rotates to a certain position, the elastic buckles 82 installed in the movable groove 81 by two first return springs 83 are inserted into the positioning groove 92 opened on one side of the arc plate 9. The control panel 8 drives the arc plate 9 to rotate in the groove 2. The plate 5 rotates so that the discharge through hole 91 in the arc plate 9 is connected to the second feed port 24, so that the steel fiber conveyed in the second discharge channel 5 is added into the mixing tank 2 through the second funnel 51. When the elastic buckle 82 installed in one side of the control panel 8 disengages from the positioning groove 92 on one side of the arc plate 9 due to rotation in the rotating groove 25, the arc plate 9 is reset by the second reset spring 93 installed in the two mounting grooves 26, and the steel fiber stops feeding. This cycle continues until the materials to be mixed in the steel fiber concrete are completely mixed. Through the above operation, the steel fiber to be added can be evenly added into the mixing tank 2 and mixed with other materials. This not only solves the problem of uneven mixing caused by adding steel fiber at once, but also solves the problem of low mixing efficiency of steel fiber concrete materials.

[0046] When the steel fiber concrete material is conveyed through the first discharge channel 4 and the second discharge channel 5, the switch of the vibrator 61 installed on the top surface of the connecting plate 6 is turned on.
