Description

Technical Field

[0001] This invention relates to the field of storage device technology, specifically to a mud circulation storage device and its usage method. Background Technology

[0002] In the processes of building construction, concrete production, and sand and gravel aggregate recycling, a large amount of mixtures containing mud and aggregates are often generated, such as concrete washing waste slurry, equipment flushing mud, and adhering mud generated during aggregate screening. In order to reduce resource waste and environmental pollution, it is usually necessary to recycle the above-mentioned mud and aggregates. By reusing the mud and separating and recycling the aggregates, the resource utilization rate can be improved.

[0003] In the prior art, common mud recycling devices typically collect mud centrally by setting up collection boxes or sedimentation tanks, and use simple screen structures to perform preliminary screening of aggregates, allowing some fine particles and mud to pass through the screen and enter the recycling area, while larger aggregate particles are separated. However, since the surface of the aggregates is often covered with relatively viscous mud, and the mud has a high viscosity, the mud is easy to coat the surface of the aggregates. Even after screening, it is difficult to completely remove the mud, resulting in some mud being discharged with the aggregates. This not only reduces the mud recycling efficiency but also causes a certain degree of material waste. Therefore, this application proposes a mud recycling storage device and its usage method. Summary of the Invention

[0004] The purpose of this invention is to provide a mud circulation storage device and its usage method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mud circulation storage device, comprising a storage box, a collection box detachably mounted on the outer surface of the storage box by bolts, a conveying pipe passing through and fixedly connected to the upper end of the collection box, a feeding box fixedly mounted on the upper end of the storage box by bolts, and the output end of the conveying pipe being fixedly connected to the feeding box, a transmission pipe vertically passing through the interior of the storage box, a stirring blade fixedly mounted at the bottom end of the transmission pipe, a partition plate fixedly mounted inside the collection box, the partition plate dividing the interior of the collection box into two independent chambers, a screen fixedly mounted at the end of the partition plate away from the storage box, the screen being positioned below a support rod and inclined relative to the horizontal plane, a mixing device for diluting the mud on the surface of the aggregate being provided between the support rod and the screen, and a rectangular through hole being formed on the surface of the partition plate.

[0006] As a further embodiment of the present invention, the mixing device includes multiple stabilizing cylinders, which are fixedly installed at the bottom end of the guide cylinder. An output cylinder is fixedly installed at the inner end of the stabilizing cylinder, and a spray sleeve is sleeved on the outer side of the output cylinder. The side wall surface of the spray sleeve is provided with multiple spray holes. By setting multiple stabilizing cylinders at the bottom end of the guide cylinder and integrating the output cylinder and spray sleeve structure inside the stabilizing cylinder, the dilution medium can be sprayed out at multiple points and uniformly within the guide area.

[0007] As a further embodiment of the present invention, a support tube is fixedly installed at the inner end of the spray sleeve, the support tube is axially inserted inside the output cylinder, multiple discharge holes are opened at the bottom end of the spray sleeve, an isolation cover is provided below the spray sleeve, a dispersing hopper is fixedly installed at the inner end of the stabilizing cylinder, a heating rod is fixedly connected to the bottom end of the dispersing hopper, and the heating rod is axially inserted inside the support tube. By setting a support tube inside the spray sleeve and making it axially penetrate the output cylinder, not only can it play a stable guiding role for the axial movement of the spray sleeve, but it can also provide reliable support for the arrangement of the heating rod.

[0008] As a further embodiment of the present invention, the radiating hopper and the support tube are connected by an auxiliary spring, and an extension rod is fixedly connected to the upper end of the isolation cover. The extension rod extends axially upward and passes through the inside of the support tube. The extension rod and the heating rod are connected by a buffer rope. By setting an auxiliary spring between the radiating hopper and the support tube, the radiating hopper has a certain buffering and restoring ability when subjected to force or displacement, which can reduce the rigid impact of the structure during operation and improve the overall stability and reliability of operation.

[0009] As a further embodiment of the present invention, an air compressor is fixedly installed at the inner end of the guide cylinder, a buffer cylinder is fixedly installed on the surface of the air compressor, an input pipe is fixedly installed at the inner end of the guide cylinder and the input pipe is connected to the guide cylinder, an output pipe is fixedly connected to the lower end of the buffer cylinder and the output pipe is fixedly connected to the dispersing hopper.

[0010] As a further embodiment of the present invention, an air nozzle is provided inside the output pipe, the input end of the air nozzle extends into the compressor cylinder, a passive piston is provided inside the compressor cylinder, an adjusting plug is provided inside the buffer cylinder, and the adjusting plug is fitted onto the surface of the air nozzle. The adjusting plug and the air nozzle are connected by a support spring, which is used to maintain the adjusting plug in a preset initial position. By setting an air nozzle in the output pipe and connecting the input end of the air nozzle to the compressor cylinder, and in conjunction with the passive piston structure inside the compressor cylinder, the gas can form a stable jet force under the action of force.

[0011] As a further embodiment of the present invention, a stabilizing plug is fixedly installed at the inner end of the input pipe, and a passive sleeve is sleeved on the surface of the stabilizing plug. Conducting holes are opened at corresponding positions of the stabilizing plug and the passive sleeve. By setting a stabilizing plug at the inner end of the input pipe, sleeved on the outside of the stabilizing plug, and setting conducting holes at corresponding positions of the two, the conducting holes can form a connected or misaligned state under different relative positions, thereby controlling the flow of the medium in the input pipe.

[0012] As a further embodiment of the present invention, a material distribution frame is fixedly installed at the inner end of the storage box, the transmission tube passes through the inside of the material distribution frame, and a material feeding plate is rotatably installed at the inner end of the material distribution frame, and the material feeding plate is fixedly connected to the transmission tube so that the material feeding plate can rotate synchronously with the transmission tube.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The present invention is equipped with a spray sleeve, a screen and a guiding structure in the collection box, so that the recovered mud and aggregate are successively sprayed, diluted and screened under the action of gravity and their own viscosity. The mud adhering to the surface of the aggregate is peeled off by the high temperature dilution liquid, so that the peeled mud and fine aggregate can pass through the screen smoothly for recovery, while the clean aggregate is discharged through the discharge hole, thereby effectively improving the mud recovery rate and reducing material waste.

[0015] 2. The present invention uses a linkage structure between the spray sleeve, extension rod, buffer rope and isolation cover to make the spray sleeve automatically move down under the actual action of mud and aggregate and trigger the closing of the discharge hole, thereby starting the spray dilution process. When the recycling operation stops, the spray sleeve automatically resets under the action of the elastic element, and the spraying process ends. This realizes the adaptive start and stop of diluent spraying, avoids dry spraying and accidental spraying, and reduces diluent consumption.

[0016] 3. The present invention sets a heating rod in the spray path so that the diluent is heated and atomized before spraying. The high temperature diluent can quickly release heat when it comes into contact with cold mud, which significantly reduces the viscosity of the mud and improves the dilution and stripping efficiency. Compared with the normal temperature liquid dilution method, it can reduce the amount of diluent used and shorten the processing time. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figures 1-3 A mud circulation storage device and its usage method include a storage box 1, a collection box 2 is detachably installed on the outer surface of the storage box 1 by bolts, a conveying pipe 4 is passed through and fixedly connected to the upper end of the collection box 2, a feeding box 6 is fixedly installed on the upper end of the storage box 1 by bolts, and the output end of the conveying pipe 4 is fixedly connected to the feeding box 6 to realize the directional conveying of mud between the collection box 2 and the storage box 1.

[0035] A transmission pipe 102 is vertically installed inside the storage tank 1. A stirring blade 103 is fixedly installed at the bottom end of the transmission pipe 102. The transmission pipe 102 rotates under the action of an external drive device and synchronously drives the stirring blade 103 to rotate, thereby continuously stirring the mud inside the storage tank 1, keeping the mud in a fluid state, avoiding sedimentation, stratification or solidification due to long-term standing, and improving the uniformity and reusability of the mud. A stirring motor 5 is fixedly installed at the top end of the feeding box 6, and the output end of the stirring motor 5 is fixedly connected to the transmission pipe 102.

[0036] A partition plate 109 is fixedly installed inside the collection box 2, which divides the inside of the collection box 2 into two independent chambers. In the chamber away from the storage box 1, multiple support rods 201 are fixedly installed. The multiple support rods 201 are arranged at intervals in the horizontal direction to form a barrier structure to restrict the passage of large aggregate particles, so that the slurry entering the chamber can flow through the gaps between adjacent support rods 201. A screen 3 is fixedly installed at the end of the partition plate 109 away from the storage box 1. The screen 3 is located below the support rods 201 and forms an upper and lower grading screening structure with the support rods 201, so that the slurry after the initial separation by the support rods 201 can be further finely filtered.

[0037] Specifically, the side wall surface of the collection box 2 is provided with a discharge window, which is located below the support rod 201 and is level with the lower end of the screen 3. The screen 3 is inclined relative to the horizontal plane. When the mud flows between the adjacent support rods 201, it falls onto the surface of the screen 3 and flows along the inclined direction of the screen 3. During this process, the mud is screened again to further remove the aggregate or impurities mixed in it.

[0038] Furthermore, in order to facilitate the processing of aggregates retained on the surface of screen 3 and to recover the slurry adhering to their surface, a mixing device for diluting the slurry on the surface of aggregates is provided between support rod 201 and screen 3. Rectangular through holes are provided on the surface of partition plate 109. After the slurry is screened through screen 3, it can flow into the chamber connected to conveying pipe 4 through the rectangular through holes, thereby realizing the screening, guiding and temporary storage of slurry.

[0039] like Figure 3As shown, the bottom end of the collection box 2 is fixedly installed with a feeding motor 108 by bolts, and the inner end of the conveying pipe 4 is coaxially provided with a feeding screw 107, and the feeding screw 107 is fixedly connected to the output end of the feeding motor 108. When the feeding motor 108 is working, it drives the feeding screw 107 to rotate, thereby conveying the mud inside the collection box 2 to the inside of the feeding box 6 along the conveying pipe 4, so as to realize the stable transfer of mud.

[0040] Example 2: Please refer to Figures 4-7 A mud circulation storage device and its usage method are based on Embodiment 1. The mixing device includes multiple stabilizing cylinders 203, which are fixedly installed at the bottom end of the guide cylinder 202. An output cylinder 301 is fixedly installed at the inner end of the stabilizing cylinder 203. A spray sleeve 204 is sleeved on the outer side of the output cylinder 301, and multiple spray holes (not shown in the figure) are opened on the side wall surface of the spray sleeve 204 for spraying the internal medium in an atomized form.

[0041] Among them, a limit ring is fixedly installed at the bottom end of the output cylinder 301. When the spray sleeve 204 moves axially relative to the output cylinder 301 during operation, the limit ring can limit the spray sleeve 204 to prevent it from falling off the output cylinder 301, thereby ensuring the stability and reliability of the spray structure.

[0042] A support tube 304 is fixedly installed at the inner end of the spray sleeve 204. The support tube 304 passes through the inside of the output cylinder 301 along the axial direction. Multiple discharge holes 305 are opened at the bottom end of the spray sleeve 204. The discharge holes 305 are arranged in a ring. An isolation cover 306 is provided below the spray sleeve 204. A dispersing hopper 208 is fixedly installed at the inner end of the stabilizing cylinder 203. A heating rod 303 is fixedly connected to the bottom end of the dispersing hopper 208. The heating rod 303 passes through the inside of the support tube 304 along the axial direction.

[0043] Specifically, the surface of the support tube 304 has multiple strip-shaped through holes. The support tube 304 is not made of metal. On the one hand, the good thermal conductivity of the metal material is used to quickly conduct the heat generated by the heating rod 303 to the environment inside the output cylinder 301. The dispersing hopper 208 is connected to the support tube 304 by an auxiliary spring 302. As the mud flows in from above the guide cylinder 202, due to the viscous physical properties of the mud itself, it will adhere to the surface of the spray sleeve 204 and move downward under the action of gravity. Furthermore, a protrusion is fixedly installed at the bottom end of the heating rod 303. The protrusion passes through the inside of the strip-shaped through holes. The strip-shaped through holes guide and limit the protrusion to prevent the support tube 304 from moving excessively in the axial direction and ensure the stability of the spray structure during operation.

[0044] An extension rod 308 is fixedly connected to the upper end of the isolation cover 306. The extension rod 308 extends upward along the axial direction and passes through the inside of the support tube 304. The extension rod 308 is connected to the heating rod 303 by a buffer rope 307. The bottom end of the heating rod 303 is not provided with a heating section to avoid thermal impact on the buffer rope 307.

[0045] In the initial state, the buffer rope 307 is in a relaxed state, and the isolation cover 306 and the discharge hole 305 are kept apart, so that the discharge hole 305 is in an open state. When the spray sleeve 204 moves downward under the action of external force, the extension rod 308 moves downward synchronously with the spray sleeve 204, and the buffer rope 307 gradually transitions from a relaxed state to a stretched state, and finally becomes taut.

[0046] As the buffer rope 307 is tightened, the isolation cover 306, driven by the extension rod 308, moves upward to adhere to the bottom end of the spray sleeve 204, thereby blocking the discharge hole 305 and switching the discharge hole 305 from the open state to the closed state, so as to realize automatic shut-off and leak prevention control during the spraying process.

[0047] like Figures 6-9 As shown, a compressor cylinder 207 is fixedly installed at the inner end of the guide cylinder 202, a buffer cylinder 206 is fixedly installed on the surface of the compressor cylinder 207, an input pipe 205 is fixedly installed at the inner end of the guide cylinder 202, and the input pipe 205 is connected to the guide cylinder 202. The input end of the guide cylinder 202 is connected to a water pump for conveying diluent into each guide cylinder 202.

[0048] The lower end of the buffer cylinder 206 is fixedly connected to the output pipe 209, which is fixedly connected to the dispersing hopper 208. The diameter of the dispersing hopper 208 matches the inner diameter of the stabilizing cylinder 203 to prevent liquid splashing or deviation.

[0049] An air nozzle 401 is inserted inside the output pipe 209. The air nozzle 401 is L-shaped (e.g., Figure 9 As shown), the input end of the nozzle 401 extends into the compressor cylinder 207. The compressor cylinder 207 is equipped with a passive piston 402. The passive piston 402 and the compressor cylinder 207 are elastically connected by a compression spring 403, so that the passive piston 402 can automatically reset after being subjected to force.

[0050] The buffer cylinder 206 is provided with an adjusting plug 407 inside, and the adjusting plug 407 is sleeved on the surface of the jet nozzle 401, forming a variable volume buffer space between the adjusting plug 407 and the inner wall of the buffer cylinder 206. As the adjusting plug 407 is displaced in the axial direction, the volume of the space inside the buffer cylinder 206 changes accordingly.

[0051] like Figure 9 , Figure 10As shown, the regulating plug 407 and the jet nozzle 401 are connected by a support spring 408. The support spring 408 is used to maintain the regulating plug 407 in a preset initial position. When the regulating plug 407 undergoes axial displacement under the action of external force, the support spring 408 can drive the regulating plug 407 to automatically return to the initial position when the external force is released, thereby ensuring the stability and repeatability of the device.

[0052] A stabilizing plug 404 is fixedly installed at the inner end of the input pipe 205. A passive sleeve 406 is sleeved on the surface of the stabilizing plug 404. Conducting holes 409 are opened at corresponding positions of the stabilizing plug 404 and the passive sleeve 406. The conducting holes 409 of the two are axially aligned and staggered. When the passive sleeve 406 is displaced relative to the stabilizing plug 404, causing the two conducting holes 409 to be in a misaligned state, the diluent in the input pipe 205 cannot flow into the buffer cylinder 206 through the conducting holes 409, thereby realizing the closure or flow restriction control of the diluent flow path.

[0053] A rectangular block is fixedly installed on the inner end of the passive sleeve 406. A groove matching the rectangular block is opened on the outer surface of the stabilizing plug 404. The rectangular block is slidably disposed in the groove to limit the rotation of the passive sleeve 406 during movement and ensure that the passive sleeve 406 slides linearly only in the axial direction. A guide rod 405 is fixedly installed on the end of the passive sleeve 406 away from the stabilizing plug 404. The end of the guide rod 405 is fixedly connected to the adjusting plug 407.

[0054] like Figure 2 , Figure 11 As shown, a material distribution frame 101 is fixedly installed at the inner end of the storage box 1, and a transmission pipe 102 passes through the inside of the material distribution frame 101. A material feeding plate 105 is rotatably installed at the inner end of the material distribution frame 101, and the material feeding plate 105 is fixedly connected to the transmission pipe 102 so that the material feeding plate 105 can rotate synchronously with the transmission pipe 102.

[0055] Two sets of through holes 104 are provided on the outer wall surface of the transmission pipe 102. The two sets of through holes 104 are located on the upper and lower sides of the material distribution frame 101, respectively. A lifting screw rod 106 is fixedly installed inside the transmission pipe 102. When the transmission pipe 102 rotates, it can drive the stirring blade 103 at its bottom end to continuously stir the mud inside the storage tank 1. On the other hand, it can also transport the mud upward along the axial direction to the top of the material distribution frame 101 through the lifting screw rod 106, and make the mud fall back from the height to the inside of the storage tank 1, thereby forming an up-and-down circulating flow path.

[0056] The side wall surface of the material distribution frame 101 is provided with multiple outflow holes. During the rotation of the transmission tube 102, the material feeding plate 105 rotates synchronously, causing the mud falling on the surface of the material feeding plate 105 to be thrown outward under the action of centrifugal force, and then evenly sprinkled from the circumference of the material distribution frame 101 into the storage box 1 through the outflow holes. This enhances the dispersion effect of the mud, avoids local accumulation, and ensures that the mud always maintains good fluidity and uniformity.

[0057] The working principle of this invention is:

[0058] When in use, the recycled mud is poured into the inside of the collection box 2. At this time, the mud and aggregate continuously flow over the surface of the spray sleeve 204. Due to the viscosity of the mud itself and the action of gravity, the spray sleeve 204 moves downward. When the spray sleeve 204 moves downward under the action of external force, the extension rod 308 moves downward synchronously with the spray sleeve 204. At this time, the auxiliary spring 302 is stretched, and the buffer rope 307 gradually transitions from a relaxed state to a stretched state, and finally becomes taut.

[0059] As the buffer rope 307 is tightened, the isolation cover 306, driven by the extension rod 308, moves upward to adhere to the bottom end of the spray sleeve 204, thereby blocking the discharge hole 305 and switching the discharge hole 305 from the open state to the closed state. At this time, the diluent flowing from the input pipe 205 passes through the stabilizing plug 404 and pushes the adjusting plug 407 to move. Then, during the movement of the adjusting plug 407, it compresses the support spring 408. Subsequently, the adjusting plug 407 is exposed inside the compressor cylinder 207. At this time, the diluent flows into the interior of the adjusting plug 407 and pushes the passive piston 402 to move under the action of pressure. As the internal pressure of the compressor cylinder 207 increases, the diluent flows into the interior of the nozzle 401 and is then sprayed out from the nozzle 401. The sprayed diluent is then heated by the heating rod 303.

[0060] At this time, the heated diluted liquid is sprayed out from the spray hole on the surface of the spray sleeve 204, which splashes the mud on the surface of the aggregate between the guide cylinder 202 and the screen 3. The mud on the surface of the aggregate falls off under the action of the high temperature diluted liquid. Then the mud that falls off carries the smaller aggregate through the screen 3, thereby realizing the recovery of the mud on the surface of the unqualified aggregate. Then the aggregate that has been stripped of mud by the diluted liquid flows out from the discharge hole 305 on the surface of the collection box 2.

[0061] The conveying pipe 4 transports the mud inside the collection box 2 to the inside of the feeding box 6, and then flows out from the distribution frame 101, and finally stores the mud inside the storage box 1;

[0062] When the diluent is no longer flowing in the input pipe 205, the recovery operation stops. The spray sleeve 204 returns to its initial state under the elastic force of the auxiliary spring 302. At this time, the compression spring 403 begins to release pressure after being squeezed by the passive piston 402, and pushes the passive piston 402 to gradually reset, and then squeezes out the diluent inside the compressor cylinder 207.

[0063] As the spray sleeve 204 resets, the extension rod 308 moves upward and contacts the bottom end of the heating rod 303 until the isolation cover 306 moves downward. At this time, the diluent inside the air compressor 207 flows into the interior of the spray sleeve 204, diluting the residual mud inside, and then flows out from the discharge hole 305.

[0064] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

The passive piston (402) and the compressor cylinder (207) are elastically connected by a compression spring (403). An adjusting plug (407) is provided inside the buffer cylinder (206). The adjusting plug (407) is sleeved on the surface of the air nozzle (401). The adjusting plug (407) and the air nozzle (401) are connected by a support spring (408). The support spring (408) is used to maintain the adjusting plug (407) in a preset initial position.

4. The mud circulation storage device according to claim 3, characterized in that: A stabilizing plug (404) is fixedly installed at the inner end of the input tube (205). A passive sleeve (406) is sleeved on the surface of the stabilizing plug (404). Conducting holes (409) are opened at corresponding positions of the stabilizing plug (404) and the passive sleeve (406).

5. A mud circulation storage device according to claim 1, characterized in that: The inner end of the storage box (1) is fixedly installed with a material distribution frame (101), and the transmission pipe (102) passes through the inside of the material distribution frame (101). The inner end of the material distribution frame (101) is rotatably installed with a material feeding plate (105), and the material feeding plate (105) is fixedly connected to the transmission pipe (102) so that the material feeding plate (105) can rotate synchronously with the transmission pipe (102).

6. A method for using a mud circulation storage device according to any one of claims 1-5, characterized in that, Includes the following steps: S1: The isolation cover (306) is driven by the extension rod (308) to adhere to the bottom end of the spray sleeve (204) upward, thereby blocking the discharge hole (305) and switching the discharge hole (305) from the open state to the closed state. At this time, the diluent flowing from the input pipe (205) passes through the stabilizer (404) and pushes the regulating plug (407) to move. Then, during the movement of the regulating plug (407), it compresses the support spring (408). Then, the regulating plug (407) is exposed inside the compressor cylinder (207). At this time, the diluent flows into the interior of the regulating plug (407) and pushes the passive piston (402) to move under the action of pressure. As the internal pressure of the compressor cylinder (207) increases, the diluent flows into the interior of the nozzle (401) and is then sprayed out from the nozzle (401). The sprayed diluent is then heated by the heating rod (303). S2: Slurry splashes on the surface of aggregate between the guide cylinder (202) and the screen (3). At this time, the slurry on the surface of the aggregate falls off under the action of the high temperature diluent. Then the fallen slurry carries the aggregate that can pass through the screen (3) through the screen, thereby realizing the recycling of the slurry on the surface of the unqualified aggregate. Then the aggregate that has been stripped of slurry by the diluent flows out from the discharge hole (305) on the surface of the collection box (2). S3: When the diluent stops flowing in the input pipe (205), the recovery operation stops. The spray sleeve (204) returns to its initial state under the elastic force of the auxiliary spring (302). At this time, the compression spring (403) begins to release pressure after being squeezed by the passive piston (402) and pushes the passive piston (402) to gradually reset, and then squeezes out the diluent inside the compressor cylinder (207).
