Description

Technical Field

[0001] This invention belongs to the field of fluidized solidified soil production, specifically a powder storage device for fluidized solidified soil production. Background Technology

[0002] Premixed fluidized solidified soil is a mixture of various discarded engineering waste, soil solidifying agents, and water in a certain proportion to achieve certain performance indicators. It is a green and innovative material with significant social implications for energy conservation, emission reduction, and comprehensive utilization of industrial solid waste.

[0014] Preferably, a radar level gauge is also installed on the top surface of the tank.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This invention involves weighing powder from a storage tank assembly into a weighing hopper assembly. Once a preset value is reached, the discharge port of the storage tank assembly closes, and the weighing hopper assembly opens, allowing the powder to enter the feeding assembly. During the weighing and discharging process, a power assembly drives the feeding assembly to transport the powder. Simultaneously, the power assembly drives a stirring assembly in the inner cavity of the mounting frame to stir the powder, thereby preventing the powder from becoming damp and clumping due to prolonged stagnation, which could lead to conveying blockages. Furthermore, the weighing hopper assembly enables precise powder delivery, solving the problem of inaccurate manual feeding.

[0017] 2. This invention, while the stirring component is working, uses a screening component connected to the stirring component to vibrate and screen the powder during the powder's descent, filtering out clumps and hardened powder. That is, clumps of powder remain in the inner cavity of the storage tank component, preventing clumps of hardened powder from entering the weighing hopper component and affecting production. At the same time, the vibration of the screening component disperses the powder that is still loose even if it is clumped, thereby preventing large-scale powder clumping and affecting production.

[0018] 3. This invention drives the feeding component to work simultaneously with the stirring component in several storage tank components via a power component. Furthermore, the stirring component in each storage tank component drives the screening component within it, thereby achieving simultaneous stirring and filtering of powder in several storage tank components. Its compact structure not only saves manufacturing costs and reduces space occupancy but also reduces energy consumption in the production process. When production is stopped, the powder in the storage tank components can be stirred periodically by periodically starting the power component, avoiding the problem of localized dampness and clumping caused by long-term static storage of powder.

[0019] 4. In the feeding process, the powder can quickly enter the hopper through the vibrating screen plate. The weight of the powder in the hopper is monitored by the weighing sensor on the hopper. After the powder reaches the preset value, the electric hydraulic telescopic rod retracts to close the discharge hopper door, and then the hopper door at the bottom of the hopper opens. The powder enters the feed inlet through the rubber corrugated guide pipe, and then the rotating screw conveys the powder falling from the feed inlet to the discharge outlet. This solves the problem of powder accumulating in the traditional powder conveying tank and not entering the screw feeding mechanism. Attached Figure Description

[0035] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0036] Example 1:

[0037] Reference Appendix Figure 1 To be continued Figure 7As shown, a powder storage device for the production of fluidized solidified soil includes a mounting frame 1. Several sets of storage tank assemblies 2 are installed in the middle of the top surface of the mounting frame 1. Weighing hopper assemblies 3 are installed at the discharge ports of the several sets of storage tank assemblies 2. A feeding assembly 4 matching the weighing hopper assembly 3 is installed directly below the weighing hopper assembly 3 on the mounting frame 1. A stirring assembly 6 is installed in the middle of the inner cavity of the storage tank assembly 2. A screening assembly 7 is also installed in the inner cavity of the storage tank assembly 2. A power assembly 5 for driving the feeding assembly 4 and the stirring assembly 6 is installed on the mounting frame 1.

[0038] As can be seen from the above, the powder is stored in the storage tank assembly 2. During production, the powder in the storage tank assembly 2 enters the weighing hopper assembly 3 for weighing. After reaching the preset value, the discharge port of the storage tank assembly 2 is closed, and the weighing hopper assembly 3 is opened to allow the powder to enter the feeding assembly 4. During the weighing and feeding process, the feeding assembly 4 is driven by the power assembly 5 to transport the powder. At the same time, the stirring assembly 6 in the inner cavity of the mounting frame 1 is driven by the power assembly 5 to stir the powder, so as to avoid the powder from standing for a long time and clumping in some areas.

[0039] While the stirring component 6 is working, the screening component 7 connected to the stirring component 6 vibrates and screens the powder during the powder falling process, filtering out the agglomerated and hardened powder. That is, the agglomerated powder remains in the inner cavity of the storage tank component 2, preventing the agglomerated and hardened powder from entering the weighing hopper component 3 and affecting production. At the same time, the vibration of the screening component 7 disperses the powder that is still loose even though it is agglomerated, thereby preventing the powder from agglomerating in large quantities and affecting production.

[0040] The above is specifically described as follows: The remaining amount of powder in the tank 201 is monitored by the radar level sensor on the top surface of the tank 201, and the powder is added into the inner cavity of the tank 201 through the feeding port 202. During production, the motor 501 is started, and the rotation of the motor 501 drives the feeding screw 402 in the screw housing 401 to rotate. The drive gear 503 installed on the outer wall of the rotating end of the motor 501 rotates accordingly. The rotation of the drive gear 503 drives the driven gear 504 meshing with it to rotate, which in turn drives the first connecting rod 505 in the middle of the driven gear 504 to rotate. The first sprocket 506 at the end of the first connecting rod 505 cooperates with the chain 507 and the second sprocket 508 to drive the second connecting rod 509 to rotate. The second connecting rod 509 then drives several sets of agitator shafts 601 connected end to end to rotate. The agitator blades 602 on the agitator shafts 601 agitate the powder in the tank 201.

[0041] During the rotation of the stirring shaft 601, the U-shaped blocks 704 at both ends rotate, thereby driving the third connecting rod 703 to move. With the cooperation of the U-shaped blocks 704, the third connecting rod 703 and the concave seat 702, the sieve plate 701 on the bottom surface of the inner cavity of the tank 201 is driven to move up and down repeatedly.

[0042] The extension of the electric hydraulic telescopic rod 205 causes the L-shaped block 204 to slide horizontally, thereby opening the discharge hopper door 203 on the bottom surface of the feeding port 202. Powder falls from the bottom surface of the tank 201 into the hopper 301. During the feeding process, the powder can quickly pass through the sieve plate 701 into the hopper 301. As the powder passes through the sieve holes of the sieve plate 701, clumps of hardened powder are filtered out, preventing them from entering the hopper 301. In section 01, the weighing sensor 302 on the hopper 301 monitors the weight of the powder in the hopper 301. After the powder reaches the preset value, the electric hydraulic telescopic rod 205 retracts to drive the discharge hopper door 203 to close, and then the hopper door on the bottom of the hopper 301 opens. The powder enters the feed inlet 403 through the rubber corrugated guide pipe 303, and then the rotating feeding screw 402 transports the powder falling in the feed inlet 403 to the discharge outlet 404 for discharge.

[0043] Above, the power component 5 drives the feeding component 4 to work, while driving the stirring component 6 in several storage tank components 2 to work. Furthermore, the stirring component 6 in each storage tank component 2 drives the screening component 7 inside it to work, thereby realizing the simultaneous stirring and filtering of powder in several storage tank components 2, reducing energy consumption in the production process.

[0044] Furthermore, in the event of production stoppage, the power component 5 is periodically activated to achieve periodic stirring of the powder in the storage tank component 2, thereby preventing the powder from becoming damp and clumping in localized areas due to prolonged stagnation. This solves the problem of powder becoming damp, clumping, and hardening in localized areas when traditional storage tanks are not used for extended periods.

[0045] Example 2:

[0046] Reference Appendix Figure 1 To be continued Figure 7 As shown, the storage tank assembly 2 includes a tank body 201, a feeding port 202 is installed on the top surface of the tank body 201, a discharge hopper door 203 is slidably installed at the lower end of the front wall of the tank body 201, an L-shaped block 204 is installed on the front wall of the discharge hopper door 203, and an electric hydraulic telescopic rod 205 is installed on the front wall of the tank body 201. The telescopic end of the electric hydraulic telescopic rod 205 is fixedly installed with the front wall of the L-shaped block 204.

[0047] The powder is added into the inner cavity of the tank 201 through the feeding port 202. The extension of the electric hydraulic telescopic rod 205 causes the L-shaped block 204 to slide horizontally, thereby driving the discharge hopper door 203 at the bottom of the feeding port 202 to open, and the powder falls from the bottom of the tank 201 into the hopper 301.

[0048] The stirring assembly 6 includes a stirring shaft 601 rotatably installed in the middle of the inner cavity of the tank 201. A plurality of stirring blades 602 are installed on the outer wall of the stirring shaft 601, and the plurality of stirring blades 602 are staggered around the axis of the stirring shaft 601.

[0049] Above, several stirring blades 602 distributed alternately on the stirring shaft 601 fully stir the powder in the inner cavity of the tank 201, avoiding the powder from clumping due to long-term static standing;

[0050] The screening assembly 7 includes a screen plate 701 slidably installed at the lower end of the inner cavity of the tank 201 and U-shaped blocks 704 symmetrically fixed at both ends of the stirring shaft 601. Concave seats 702 are fixedly installed at both ends of the top surface of the screen plate 701. A third connecting rod 703 is rotatably installed on each of the two concave seats 702. The upper end of the third connecting rod 703 is rotatably installed in the middle of the U-shaped block 704 on the same side.

[0051] The two ends of adjacent stirring shafts 601 in a number of sets of stirring shafts 601 are fixedly connected;

[0052] Above, the second connecting rod 509 rotates, driving several sets of stirring shafts 601 connected end to end to rotate. The stirring blades 602 on the stirring shafts 601 stir the powder in the tank 201, preventing the powder from sitting for a long time and clumping in some areas. During the rotation of the stirring shafts 601, the U-shaped blocks 704 at both ends rotate with it, thereby driving the third connecting rod 703 to move. With the cooperation of the U-shaped blocks 704, the third connecting rod 703 and the concave seat 702, the sieve plate 701 on the bottom surface of the inner cavity of the tank 201 is driven to move up and down reciprocally. This can be understood as the sieve plate 701 being in a vibrating state.

[0053] The weighing hopper assembly 3 includes a hopper 301, four weighing sensors 302 are evenly distributed on the top surface of the hopper 301, the upper end of the weighing sensors 302 is fixedly installed to the bottom surface of the tank 201, and a rubber corrugated guide pipe 303 is fixedly installed on the bottom surface of the hopper 301.

[0054] When the discharge hopper door 203 on the bottom surface of the tank 201 is opened, the powder enters the inner cavity of the hopper 301 and the weighing sensor 302 on the hopper 301 monitors the weight of the powder in the hopper 301. After the powder reaches the preset value, the electric hydraulic telescopic rod 205 retracts to drive the discharge hopper door 203 to close, and then the hopper door on the bottom surface of the hopper 301 opens, and the powder enters the feed inlet 403 through the rubber corrugated guide pipe 303.

[0055] The feeding assembly 4 includes a screw housing 401, a feeding screw 402 is installed in the rotating middle of the inner cavity of the screw housing 401, a number of feed ports 403 are provided on the top surface of the screw housing 401, the upper end face of the feed port 403 is fixedly connected to the bottom surface of the rubber corrugated guide tube 303, and a discharge port 404 is provided on the bottom surface of one end of the screw housing 401.

[0056] Above, the feeding screw 402 is driven to rotate by the motor 501, thereby conveying the powder falling from the feed port 403 to the discharge port 404.

[0057] Example 3:

[0058] Reference Appendix Figure 1 To be continued Figure 7 As shown, the power assembly 5 includes a motor 501 and a gearbox 502 fixedly mounted on the mounting bracket 1. The rotating end of the motor 501 passes through the gearbox 502 and is fixedly mounted to one end of the feeding screw 402. A drive gear 503 is fixedly mounted on the outer wall of the rotating end of the motor 501. The drive gear 503 is located in the inner cavity of the gearbox 502. A first connecting rod 505 is rotatably mounted in the inner cavity of the gearbox 502. A driven gear 504 is fixedly mounted on the outer wall of the first connecting rod 505 in the inner cavity of the gearbox 502. The driven gear 504 meshes with the drive gear 503. A first sprocket 506 is mounted at one end of the first connecting rod 505, which extends to the outer wall of the gearbox 502.

[0059] The power assembly 5 also includes a second connecting rod 509. A second sprocket 508 is fixedly installed on one end of the second connecting rod 509 near the first sprocket 506. A chain 507 is installed between the first sprocket 506 and the second sprocket 508. The other end of the second connecting rod 509 is fixedly connected to the end of the stirring shaft 601 in the tank 201 on the same side.

[0060] When the motor 501 rotates and drives the feeding screw 402 in the screw housing 401 to rotate, the drive gear 503 rotates and drives the driven gear 504 meshing with it to rotate, thereby driving the first connecting rod 505 in the middle of the driven gear 504 to rotate. The first sprocket 506 at the end of the first connecting rod 505 cooperates with the chain 507 and the second sprocket 508 to drive the second connecting rod 509 to rotate. The second connecting rod 509 then drives several sets of agitator shafts 601 connected end to end to rotate. The agitator blades 602 on the agitator shafts 601 agitate the powder in the tank 201 to prevent the powder from standing for a long time and clumping in some areas.

[0061] During the rotation of the stirring shaft 601, the U-shaped blocks 704 at both ends rotate, thereby driving the third connecting rod 703 to move. With the cooperation of the U-shaped blocks 704, the third connecting rod 703 and the concave seat 702, the sieve plate 701 on the bottom surface of the inner cavity of the tank 201 is driven to move up and down reciprocally. Thus, during the feeding process, the powder can quickly pass through the sieve plate 701 into the hopper 301. During the process of the powder passing through the sieve holes of the sieve plate 701, the sieve plate 701 filters out the hardened powder that has clumped, preventing the hardened powder from entering the hopper 301 and affecting production. At the same time, the up and down reciprocating motion of the sieve plate 701 disperses the powder that is still loose even if it has clumped, thereby preventing the powder from clumping together in large quantities and affecting production.

[0062] A radar level sensor is also installed on the top surface of tank 201;

[0063] The remaining amount of powder in tank 201 is monitored by a radar level sensor on the top surface of tank 201, thereby preventing powder shortage and affecting production.
