Description

Technical Field

[0001] The present invention relates to the field of concrete production equipment, in particular to a powder tank for a concrete mixing station. Background Art

[0002] Concrete is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. It is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementitious materials, granular aggregates (also called aggregates), water, and admixtures and additives added in a certain proportion, which are evenly mixed, densely formed, and cured and hardened.

[0003] Powder tanks are storage and loading and unloading products used to store raw materials for concrete production. The internal structures of powder tanks for different products are different, but a conveyor shaft is usually installed inside to facilitate the transfer of the internal products to the discharge port, and the powder falls out of the discharge port for use. However, there are still certain problems in actual use.

[0004] First of all, for powder materials with smaller product particles, since their own mass is very light, during the feeding process, static electricity will be generated due to the movement and friction between the powder and the inner wall of the tank, which will cause more powder to adhere to the inside of the tank, resulting in low powder utilization and material waste. In actual production, in order to solve the problem of low powder utilization, the staff will choose to climb the tripod outside the tank and knock on the outer wall of the tank intermittently and regularly, so as to knock the powder on the inner wall off through vibration. However, the height of the tripod is generally high, so the risk for the staff is also relatively high.

[0005] Secondly, regarding the inventory problem of powder inside the powder tank, since the powder tank itself is large and high, the remaining powder is difficult to detect. During production, sand and gravel bags are manually hung with ropes to detect the remaining powder inside the powder tank, but the accuracy is relatively low and the use is also relatively complicated. Summary of the Invention

[0006] The main purpose of the present invention is to provide a powder tank for a concrete mixing station, which can effectively solve the problems in the background technology.

[0015] A pressure sensor is installed on the surface of the steering shaft seat. There are multiple pressure sensors, and they are evenly arranged in an annular array on the rotating shaft surface of the steering shaft seat.

[0016] The steering shaft seat includes an articulated seat and a rotating tube, and the rotating tube is sleeved on the fixed axis of the articulated seat. The axial counting device includes an infrared transmitting probe and multiple infrared receiving probes. The infrared transmitting probe is installed on the fixed axis of the articulated seat, and the infrared receiving probe is arranged in a circular array on the inner wall of the rotating tube. The interior of the articulated seat is embedded with an MCU for controlling and calculating the number of rotations of the rotating tube.

[0017] The tank body includes a storage pipe, a conical pipe and a discharge pipe. A discharge shaft is installed inside the discharge pipe, a valve is installed at the discharge port of the discharge pipe, and activated carbon is inlaid at the outlet of the discharge pipe.

[0018] A baffle is installed inside the conical tube, a transmission motor is installed at the bottom of the baffle, the discharging shaft is installed on the output shaft of the transmission motor, a connecting oblique rod is installed on the surface of the baffle, and one end of the connecting oblique rod is fixed to the inner wall of the conical tube.

[0019] The baffle is configured to be in a conical shape, a conical groove is provided inside the baffle, and the transmission motor is installed inside the groove.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, a loosening motor, a main material shaft and an auxiliary material shaft are provided, and the tops of the main material shaft and the auxiliary material shaft are sharper, so that the loosening component can enter the interior of the powder material conveniently, and the pressing plate is gradually lowered, and the loosening motor is started, so that the entire loosening component can completely enter the interior of the powder material, and the pressing plate is stretched upward to loosen the powder material to prevent the accumulation of powder on the side wall.

[0023] 3. In the present invention, by setting up MCU, pressure sensor, infrared receiving probe and infrared transmitting probe, different infrared receiving probes correspond to different signal input ports, and different infrared receiving probes are marked and named 1, 2, 3...n. It is recorded that the first infrared receiving probe receives a signal starting from 0. Each time a signal is received, an electrical signal will be sent to the MCU for recording. The number of signals represents the number of rotations of the rotating tube, which can be multiplied by the circumference.

[0024] 4. In the present invention, activated carbon is provided. Since the discharge port is closest to the external air and is therefore easily affected by the external humid air, activated carbon is placed at the discharge port of the discharge pipe to absorb water vapor around the discharge port to ensure the dryness of the powder, thereby making it more convenient to discharge the powder.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0037] like Figure 1-10 As shown, a powder tank for a concrete mixing station includes a tank body 1 and a bracket 2. Figure 1 As shown, the bracket 2 is installed under the tank body 1, and is used to install the support bracket 2 so that the discharge port of the tank body 1 is at a certain height from the ground. A climbing frame 3 is installed on the surface of the tank body 1, and the staff can use the climbing frame 3 to climb to the top of the tank body 1 to inspect and maintain the tank body 1. A pressing plate 4 is installed inside the tank body 1. The pressing plate 4 is heavy to ensure that it will not shake easily. A hanging device is installed outside the tank body 1. The hanging device is used to hang the pressing plate 4 and suspend the pressing plate 4 inside the tank body 1.

[0038] The powder slowly falls from the middle part, which will cause the middle position of the powder inside the tank body 1 to be low and the positions on both sides to be high. A loosening component 5 is installed on the lower surface of the pressing plate 4, and a loosening motor 6 is installed on the top of the pressing plate 4. Figure 2 and Figure 3 As shown, the loosening motor 6 can drive the loosening assembly 5 to rotate, which can change the position of the powder in the middle and loosen it, so that the powder accumulated on both sides will fall down due to its own weight. The output shaft of the loosening motor 6 passes through the pressing plate 4 and is connected to the loosening assembly 5. The inner wall of the tank body 1 is provided with a guide groove 7. The top of the pressing plate 4 is installed with a guide block 8, which is stuck in the inside of the guide groove 7. The guide block 8 is stuck in the inside of the guide groove 7 to prevent the pressing plate 4 from rotating.

[0039] A vibration component 9 is installed on the side of the pressing plate 4, which is used to vibrate the inner wall of the tank body 1. The vibration component 9 is movably connected to the loosening component 5 through a connecting device, and the connecting device is installed inside the pressing plate 4. Since static electricity is generated due to the movement and friction between the powder and the inner wall of the tank body 1, more powder will adhere to the inside of the tank body 1. Therefore, the vibration component 9 is used to regularly hit the inner wall of the tank body 1, and the powder adsorbed on the surface of the tank body 1 is knocked down by vibration, thereby improving the utilization rate of the powder.

[0040] like Figure 2 As shown, the loading and lifting device includes a plate placing steel rope 10 and a rope winding frame 11. The number of plate placing steel ropes 10 is set to two, and the rope winding frame 11 is divided into two areas. The two plate placing steel ropes 10 are respectively fixedly installed at symmetrical positions of the pressing plate 4. A guide shaft seat 12 and a steering shaft seat 13 are installed on the surface of the tank body 1. The guide shaft seat 12 is installed at the top position of the tank body 1, and the axial shaft seat 13 is installed at the corner position of the top of the tank body 1. One end of the plate placing steel rope 10 is fixed and wound around the surface of the rope winding frame 11, and the other end of the plate placing steel rope 10 passes through the guide shaft seat 12 and the steering shaft seat 13 in sequence and passes through the tank body 1 and is fixedly connected to the surface of the pressing plate 4. A rope winding motor 14 is installed on one side of the rope winding frame 11, and the output shaft of the rope winding motor 14 is fixedly connected to the rotating shaft of the rope winding frame 11;

[0041] When in use, start the rope winding motor 14, and the output shaft of the rope winding motor 14 drives the rotating shaft of the rope winding frame 11 to rotate, and reel in and unreel the plate release steel rope 10, and indirectly adjust the height of the pressing plate 4 to adapt to different residual amounts of powder inside the tank body 1. During initial use, it is necessary to first use the plate release steel rope 10 to retract the pressing plate 4 to the top position inside the tank body 1. After the powder is transferred inside the tank body 1, the height of the pressing plate 4 can be adjusted to control the powder dust from floating in the air and accelerate the deposition of dust.

[0042] like Figure 4 As shown, the loosening component 5 includes a main material shaft 5a and an auxiliary material shaft 5b. The main material shaft 5a and the auxiliary material shaft 5b are both feed shafts. The main material shaft 5a is installed in the middle position of the pressing plate 4. There are multiple auxiliary material shafts 5b and they are arranged in a circular array around the main material shaft 5a to improve the loosening effect. It should be noted that the tops of the main material shaft 5a and the auxiliary material shaft 5b are relatively sharp, which makes it convenient for the loosening component 5 to enter the interior of the powder, gradually lower the pressing plate 4, and start the loosening motor 6 to facilitate the entire loosening component 5 to completely enter the interior of the powder, and stretch the pressing plate 4 upward to loosen the powder to prevent the accumulation of powder on the side wall. The coordinated use of the main material shaft 5a and the auxiliary material shaft 5b can increase the area of ​​the loosening material.

[0043] like Figure 5As shown, the connecting device includes a main gear 15 and a connecting gear 16. The diameter of the main gear 15 is much larger than the diameter of the connecting gear 16 to ensure that the main gear 15 can mesh with the connecting gear 16, but the connecting gears 16 will not mesh with each other. The number of connecting gears 16 is the same as the number of auxiliary material shafts 5b. The main gear 15 is sleeved on the surface of the main material shaft 5a, and the connecting gear 16 is sleeved on the surface of the auxiliary material shaft 5b. The main gear 15 meshes with the connecting gear 16.

[0044] like Figure 5 As shown, the vibration material assembly 9 includes a gear rod 9a and a vibration rod 9b, the gear rod 9a and the vibration rod 9b are fixedly connected, the gear rod 9a is engaged with the connecting gear 16, the number of gear rods 9a and the number of auxiliary material shafts 5b are set to the same. In this embodiment, the number of vibration rods 9b and the number of gear rods 9a are both five, one end of the vibration rod 9b is fixed through the pressing plate 4 and extends to the outer end of the pressing plate 4. Since the number of gear rods 9a is five, the number of connecting gears 16 is also five. Therefore, in order to ensure that the gear rods 9a do not hinder each other during movement, the angle formed by the two adjacent gear rods 9a is 108°, and the lengths of the gear rods 9a and the vibration rod 9b are exactly the same.

[0045] like Figure 7 As shown, a pressure sensor 17 is installed on the surface of the steering shaft seat 13, and there are multiple pressure sensors 17. The plate release steel rope 10 passes through the surface of the steering shaft seat 13. Since the pressing plate 4 pulls the plate release steel rope 10, the plate release steel rope 10 applies pressure to the surface of the pressure sensor 17, so that the pressure sensor 17 generates a pressure indication, and a uniform annular array is formed on the rotating shaft surface of the steering shaft seat 13 to ensure that pressure is applied to the surface of the pressure sensor 17 regardless of the rotation of the steering shaft seat 13. An axial counting device is installed on the surface of the steering shaft seat 13 to calculate the length of the release rope and convert it into the remaining amount of powder inside the tank body 1.

[0046] like Figure 8 As shown, the steering shaft seat 13 includes an articulated seat 13a and a rotating tube 13b. The rotating tube 13b is sleeved on the fixed axis of the articulated seat 13a. The axial counting device includes an infrared emitting probe 18 and multiple infrared receiving probes 19. The infrared emitting probe 18 is installed on the fixed axis of the articulated seat 13a. The infrared receiving probe 19 is arranged in a circular array on the inner wall of the rotating tube 13b. The rotation of the rotating tube 13b can drive the infrared receiving probe 19 to rotate. The infrared light emitted by the infrared emitting probe 18 corresponds to the length of the plate steel rope 10 when the rotating tube 13b rotates to different positions. The interior of the articulated seat 13a is embedded with an MCU 20 for controlling and calculating the number of rotations of the rotating tube 13b.

[0047] The specific calculation method inside MCU20 is: different infrared receiving probes 19 correspond to different signal input ports, different infrared receiving probes 19 are marked and named 1, 2, 3...n, and the first infrared receiving probe 19 receives a signal starting from 0. Each time a signal is received, an electrical signal will be sent to MCU20 for recording. The number of signals represents the number of rotations of the rotating tube 13b, which can be multiplied by the circumference. However, there is still a certain error in the calculation using this method. Therefore, MCU20 is instructed to record each infrared receiving probe 19, but given the first electrical signal, the previous data is discarded, and the signals of other infrared receiving probes 19 are re-recorded. The last recorded signal is the final signal, and the angle between it and the first signal is multiplied by the circumference, and the data of the first signal recorded previously is added for calculation.

[0048] like Figure 1 As shown, the tank body 1 includes a storage pipe 1a, a cone pipe 1b and a discharge pipe 1c. The cone pipe 1b is fixed below the storage pipe 1a, and the discharge pipe 1c is fixed below the cone pipe 1b. The installation method can be fixed by welding, as shown in FIG. Figure 9 As shown, a discharge shaft 21 is installed inside the discharge pipe 1c, and a valve 22 is installed at the discharge port of the discharge pipe 1c. Discharge can be carried out by opening the valve 22. Activated carbon 23 is embedded at the outlet of the discharge pipe 1c.

[0049] Since the discharge port is closest to the external air, it is easily affected by the external humid air. Activated carbon 23 is placed at the discharge port of the discharge pipe 1c to absorb water vapor around the discharge port to ensure the dryness of the powder, thereby making it more convenient to discharge the powder.

[0050] like Figure 6 As shown, a baffle 24 is installed inside the conical tube 1b, a transmission motor 25 is installed at the bottom of the baffle 24, the discharge shaft 21 is installed on the output shaft of the transmission motor 25, and a connecting oblique rod 26 is installed on the surface of the baffle 24. The baffle 24 is fixed to the middle position of the conical tube 1b by the connecting oblique rod 26, and one end of the connecting oblique rod 26 is fixed to the inner wall of the conical tube 1b. The baffle 24 not only provides the function of blocking the material, but also provides the function of installation and fixing.

[0051] like Figure 9 As shown, the baffle 24 is configured to be conical in shape, which can prevent powder from accumulating on the surface of the baffle 24 . A conical groove is provided inside the baffle 24 , and the transmission motor 25 is installed inside the groove.

[0052] It should be noted that the present invention is a powder tank for a concrete mixing station. When in use, first open the valve 22 and start the transmission motor 25. Its output shaft drives the discharge shaft 21 to make the powder inside the tank body 1 fall out. After the discharge is completed, start the rope motor 14. At this time, the rope frame 11 is unwound, and the plate steel rope 10 is used to make the pressure plate 4 fall to the position of the powder. At this time, the final location of the fall can be judged according to the data on the surface of the pressure sensor 17. At this time, start the loosening motor 6, and the output shaft of the loosening motor 6. The output shaft of the loosening motor 6 drives the main material shaft 5a to rotate, and at the same time drives the main gear 15 to rotate. Since the main gear 15 and the connecting gear 16 are engaged, it drives the connecting gear 16 to rotate, and the auxiliary material shaft 5 b will also rotate accordingly, gradually making the main material shaft 5a and the auxiliary material shaft 5b completely enter the powder. At this time, the connecting gear 16 rotates to drive the gear rod 9a to move, and the gear rod 9a will drive the vibration rod 9b to move, so that the vibration rod 9b hits the inner wall of the tank body 1, causing the accumulated adsorbed inside the tank body 1 to vibrate and fall. Then start the rope winding motor 14 to wind up the plate steel rope 10, lift the powder in the middle of the tank body 1, and facilitate the falling of the powder accumulated on both sides, thereby improving the overall use efficiency of the powder. Observe the data of the pressure sensor 17. When the data of the pressure sensor 17 begins to stabilize, pull the pressing plate 4 upward. At this time, the data calculated by the MCU20 is the height of the powder, which can only calculate the amount of residual material.
