Description

Technical Field

[0001] This invention relates to the field of mixing equipment technology, specifically to a pressure slurry tank with anti-sealing failure and its usage method. Background Technology

[0002] A mixing device is a piece of equipment used to uniformly mix two or more materials. It is widely used in industries such as chemical, food, pharmaceutical, and agriculture. Its core function is to uniformly combine materials of different components and forms through physical means to form a mixture with uniform composition and stable performance. There are many types of mixing devices. Among them, the slurry tank is a type of equipment commonly used in wet mixing. It is mainly used to fully mix liquid slurry with solid materials to ensure uniform distribution of the slurry, improve the stability of subsequent processes and product quality, and is widely used in ceramics, coatings, metallurgy and other fields.

[0003] The pressure inside the slurry tank is usually precisely regulated by a pressure regulating valve. Then, the pre-mixed slurry is drawn into the tank through the feed pipe and brought into full contact with the solid materials inside. At the same time, the stirring paddle inside the tank will rotate continuously at high speed to shear and stir the material, further enhancing the fusion effect of the solid and liquid phases and avoiding problems such as clumping and stratification. Finally, a slurry product with uniform texture is prepared.

[0004] In the actual operation of the slurry tank, precise control of the internal pressure is a key prerequisite for achieving uniform slurry intake. Especially when intake of multiple slurries, it is necessary to control the intake rate of different slurries by adjusting the internal pressure. The ideal operating procedure is to first balance the air pressure inside and outside the tank, and then make precise pressure adjustment. However, when the device directly fills the tank with air through the pressure regulating valve to balance the air pressure inside and outside the tank, a large pressure difference will be formed instantly inside and outside the tank. It is impossible to achieve air pressure balance in a short time, which can easily cause the tank to collapse and deform due to negative pressure. This seriously affects the operational stability of the slurry tank, and leads to uneven slurry intake, reducing the quality of the final mixture. Therefore, in order to solve the above problems, a pressure slurry tank with anti-sealing failure and its usage method are proposed. Summary of the Invention

The adjusting frame assembly includes two baffles, a screw is inserted into the inner side of the baffles, a piston disc is fixedly connected to one end of the screw, and a magnetic ring is adhered to one side of the piston disc.

[0008] As a further optimization of the present invention, the limiting ring is projected as an annular shape in the vertical direction, the valve stem is composed of a cylindrical body and a spherical head, and a sliding pair is formed between the inner side of the limiting ring and the valve stem body.

[0009] As a further optimization of the present invention, the fixing plate is welded to the outside of the valve stem, a sliding pair is formed between the magnetic block and the short rod, and the magnetic block is slidably disposed in the valve stem, and the valve stem and the magnetic ring are magnetically attracted to each other.

[0010] As a further optimization of the present invention, the baffle is provided with two parallel guide limiting rods, a rubber gasket is glued to one side of the baffle, an adjusting component is spirally connected to the outside of the screw, one side of the adjusting component is in contact with the side of the rubber gasket, a tension spring is sleeved on the outside of the screw, one end of the tension spring is fixedly connected to the adjusting component, and a rotating rod is installed through one end of the screw.

[0011] As a further optimization of the present invention, the horizontal pipe, the gas tank and the vertical pipe are interconnected, the outer side of the piston disc is in close contact with the inner side of the horizontal pipe, and the piston disc and the horizontal pipe are coaxially arranged.

[0012] As a further optimization of the present invention, the suction pipe assembly includes a reducing pipe, one end of the reducing pipe is connected to a fixed ball valve via a flange, one end of the fixed ball valve is connected to a feed pipe via a flange, a hollow elastic ball is installed inside the reducing pipe, an elastic plastic sheet is bonded and fixed inside the reducing pipe, and a fixing block is welded inside the reducing pipe.

[0013] As a further optimization of the present invention, the inner wall vertical cross section of the variable diameter pipe is arc-shaped, the elastic plastic sheet is arc-shaped and distributed in a ring array inside the variable diameter pipe, the side of the fixing block near the elastic plastic sheet is arc-shaped, and the projection of the fixing block along the axial direction of the variable diameter pipe is triangular.

[0014] As a further optimization of the present invention, the connecting pipe assembly includes two rigid pipes, and an elastic rubber tube is bonded and fixed between the two rigid pipes. A support ring is fixedly connected through the elastic rubber tube, and a metal elastic spring strip is fixedly connected through the inner side of the support ring. A magnetic sliding ring is sleeved on the outer side of the rigid pipe, and an elastic telescopic tube is slidably connected to the inner side of the rigid pipe. A rubber ring is bonded to one end of the elastic telescopic tube, and a magnetic plate is fixedly connected to the inner side of the elastic telescopic tube.

[0015] As a further optimization of the present invention, the following features are provided: the vertical cross-section of the elastic telescopic tube is "L"-shaped; the magnetic plate and the magnetic sliding ring are magnetically attracted to each other; the side of the metal elastic spring strip facing away from the elastic tube is attached to the outside of the elastic telescopic tube; and the side of the magnetic sliding ring near the rigid tube is arc-shaped.

[0016] A method for using a pressure slurry filling tank to prevent seal failure:

[0017] Step 1: Installation preparation work for grouting the tank: First, install and fix the gas tank and the horizontal pipe with bolts. Then, connect the flange at the upper end of the vertical pipe to the flange at the bottom end of the rotary valve. Next, connect the feed pipe to the fixed ball valve with a flange. Then, connect the fixed ball valve to the reducer with a flange. Insert the hollow elastic ball into the reducer. Finally, connect the reducer to the rigid pipe with a flange.

[0018] Step 2: Internal pressure adjustment of the tank: Rotate the rotary rod to make the screw rotate in the adjusting part and move relative to the adjusting part. While the screw moves, it pushes the piston disc to slide in the horizontal tube. The piston disc drives the magnetic ring to move closer to the magnetic block, magnetically pulling the magnetic block out of the valve stem and locking it below the limit ring. The gas valve on the gas tank controls the gas filling of the vertical and horizontal tubes. The pressure generated by the gas fills the piston disc. After overcoming the tension required for the deformation of the tension spring, the piston disc slides in the horizontal tube and drives the magnetic ring to move. After the magnetic ring moves a certain distance, the magnetic attraction on the magnetic block weakens. Under the force generated by the return spring to restore the deformation, the magnetic block slides along the short rod and returns to the valve stem. Then, rotate the rotary valve to move the valve stem upward. The gas inside the horizontal and vertical tubes fills the tank, so that the internal gas pressure of the tank quickly reaches equilibrium with the external gas pressure.

[0019] Step 3: The pressure-relief component controls the connection pipe assembly and the slurry suction pipe assembly to suction the slurry: Connect the connection pipe assembly to the pipe connecting the slurry, then control the air tank to evacuate the inside of the tank. The extracted gas passes through the riser and horizontal pipes and enters the air tank, then flows out from the exhaust port on the air tank. Simultaneously with the gas being discharged from the tank, open the fixed ball valve to connect the reducer pipe, the feed pipe, and the inside of the tank. The tank will then extract the slurry through the slurry suction pipe assembly and the connection pipe assembly. Compared with the prior art, the beneficial effects of this invention are:

[0020] 1. In this invention, a gas buffer space is constructed between the tank and the outside by setting a pressure-reducing component. By controlling the gas tank to fill the gas buffer space with a certain amount of gas, the pressure release rhythm in the gas buffer space is changed to achieve rapid balance of gas pressure inside and outside the tank. Then, the pressure inside the tank is finely adjusted to avoid tank deformation and provide a stable starting point for subsequent slurry suction.

[0021] 2. In this invention, a multi-layered protection system combining active and passive elements is formed by setting up pressure-reducing components and slurry suction pipe components. This avoids sudden changes in slurry flow rate caused by air pressure fluctuations, reduces the probability of water hammer effect from the source, and effectively buffers the initial pressure impact and smooths continuous fluctuations through the dual effects of energy absorption and flow pattern sorting of slurry fluid. It also breaks up particle agglomeration, ensuring the smoothness and uniformity of slurry flow.

[0022] 3. In this invention, the connection pipe assembly enables dynamic adjustment of the pipe cross-section. When the elastic expansion tube senses an increase in the density and flow rate of the slurry, the elastic tube will change its diameter to reduce the pipe resistance and prevent excessive impact on the connection points of various components or unstable slurry flow due to differences in slurry properties.

[0041] Please see Figures 1-14 The present invention provides a technical solution:

[0042] A pressure grouting tank with anti-sealing failure and its usage method include a support frame 1 and a tank body 2. The tank body 2 is mounted on the support frame 1, and a mixer 3 is inserted into the tank body 2. A pressure-reducing component 4 is mounted on the upper end of the tank body 2, and a grout suction pipe assembly 5 is welded to the upper end of the tank body 2. A connecting pipe assembly 6 is installed at one end of the grout suction pipe assembly 5. The pressure-reducing component 4 includes a riser 41, a limit ring 42 is fixedly connected to the inner side of the riser 41, a rotary valve 43 is mounted on the upper end of the riser 41, a valve stem 44 is inserted into the inner side of the riser 41, and a telescopic component 45 is installed inside the valve stem 44. The riser 41 passes through... A horizontal tube 46 is connected, with a gas tank 47 installed at one end of the horizontal tube 46 and an adjusting frame assembly 48 welded to the other end of the horizontal tube 46. The telescopic component 45 includes a fixing plate 451, with a short rod 452 fixedly connected to one side of the fixing plate 451. A return spring 453 is sleeved on the outside of the short rod 452, and a magnetic block 454 is fixedly connected to one end of the return spring 453. The adjusting frame assembly 48 includes two baffles 481, with a screw 484 inserted into the inside of the baffles 481. A piston disc 488 is fixedly connected to one end of the screw 484, and a magnetic ring 489 is glued to one side of the piston disc 488.

[0043] As a further implementation of this solution, the projection of the limiting ring 42 in the vertical direction is annular. The valve stem 44 consists of a cylindrical body and a spherical head. A sliding pair is formed between the inner side of the limiting ring 42 and the body of the valve stem 44. The fixing plate 451 is welded to the outer side of the valve stem 44. A sliding pair is formed between the magnetic block 454 and the short rod 452, and the magnetic block 454 is slidably disposed in the valve stem 44. The valve stem 44 and the magnetic ring 489 are magnetically attracted to each other. The shape of the limiting ring 42 allows the body of the valve stem 44 to slide up and down on its inner side without colliding with it. When the magnetic block 454... When the valve stem 44 slides along the short rod 452 due to the magnetic attraction generated by the magnetic ring 489, a part of the magnetic block 454 will protrude and be exposed on the outside of the valve stem 44. At this time, when the valve stem 44 attempts to move up and down, the protruding magnetic block 454 will make mechanical contact and interference with the inner wall of the limiting ring 42, thereby rigidly preventing the valve stem 44 from moving further. Only when the magnetic block 454 leaves the strong action area of ​​the magnetic ring 489 will it retract the protruding part into the valve stem 44, so that the gap between the valve stem 44 and the limiting ring 42 is restored, allowing the valve stem 44 to slide freely between the limiting rings 42.

[0044] As a further implementation of this scheme, two parallel guide limit rods 482 are inserted into the baffle 481. A rubber gasket ring 483 is adhered to one side of the baffle 481. An adjusting component 486 is spirally connected to the outside of the screw 484. One side of the adjusting component 486 is in contact with one side of the rubber gasket ring 483. A tension spring 485 is sleeved on the outside of the screw 484. One end of the tension spring 485 is fixedly connected to the adjusting component 486. A rotating rod 487 is installed through one end of the screw 484. The horizontal pipe 46, the gas tank 47, and the vertical pipe 41 are interconnected. The outside of the piston disc 488 is connected to... The inner side of the horizontal tube 46 is tightly fitted, and the piston disc 488 is coaxially arranged with the horizontal tube 46. Two parallel guide limit rods 482 ensure that when the two baffles 481 move relative to each other, whether they are moving closer or further apart, they remain parallel to each other. The rubber gasket ring 483 limits the adjusting member 486. When the screw 484 rotates, the adjusting member 486 remains in a fixed position due to the obstruction of the rubber gasket ring 483, while the screw 484 gradually penetrates into the horizontal tube 46 and pushes the piston disc 488 to slide within the horizontal tube 46, thereby reducing the size of the horizontal tube 46 and its connected components. The size of the sealed space in the riser 41, and the tension spring 485 fitted on the part of the screw 484 outside the horizontal pipe 46, as the relative position of the adjusting member 486 and the screw 484 changes, will gradually move the screw 484 from a stretched state to a state of near-reset as it gradually penetrates the horizontal pipe 46. The setting of the rotating rod 487 makes it easier for the operator to turn the screw 484. If it is necessary to reset the piston disc 488, air needs to be injected into the horizontal pipe 46 and the riser 41 connected to it through the air tank 47 to change the air pressure in the horizontal pipe 46. After the piston disc 488 overcomes the tension of the tension spring 485, the frictional force with the inner wall of the horizontal tube 46, and the resistance generated by other components, it resets. By adjusting the relative position of the screw 484 and the adjusting component 486, the amount of air injected by the air tank 47 into the horizontal tube 46 and the vertical tube 41 connected to it to reset the piston disc 488 can be changed. This allows for precise control of the amount of air injected by the air tank 47 when the piston disc 488 resets, thereby achieving flexible adjustment of the stability of the device when the pressure changes, and enabling the entire device to adapt to different working conditions.

[0045] As a further implementation of this solution, the suction pipe assembly 5 includes a reducing pipe 51. One end of the reducing pipe 51 is connected to a fixed ball valve 52 via a flange, and the other end of the fixed ball valve 52 is connected to a feed pipe 53 via a flange. A hollow elastic ball 54 is installed inside the reducing pipe 51, and an elastic plastic sheet 55 is bonded and fixed to the inside of the reducing pipe 51. A fixing block 56 is welded to the inside of the reducing pipe 51. The vertical cross-section of the inner wall of the reducing pipe 51 is arc-shaped, and the elastic plastic sheet 55 is also arc-shaped. The fixing blocks 56 are arranged in a ring array inside the reducer 51. The side of the fixing block 56 closest to the elastic plastic sheet 55 is arc-shaped. The projection of the fixing block 56 along the axial direction of the reducer 51 is triangular. Through the arrangement of the reducer 51, when the slurry enters the reducer 51, the arc-shaped inner wall can guide the slurry, forming a progressive constriction channel, so that the slurry flows smoothly along the pipe wall and reduces the flow dead zone. The hollow elastic ball 54 is installed inside the reducer 51. When it enters the reducer 51, it will... When the slurry is impacted, its elasticity causes it to deform. This process absorbs some of the energy from the impact and converts it into the elastic potential energy and internal energy of the hollow elastic ball 54. At the same time, after the water hammer wave of the slurry passes, the compressed hollow elastic ball 54 will rebound to its original shape. This rebound process will slowly release the previously stored energy, thereby reducing the intensity of the secondary water hammer. Throughout the process, the hollow elastic ball 54 will produce adaptive shaking and squeeze and push the elastic plastic sheet 55, causing it to deform and produce slight vibration. The slight vibration of the elastic plastic sheet 55 not only disperses the agglomerated particles in the slurry, but also increases the spacing between adjacent elastic plastic sheets 55, ensuring smooth slurry flow. The special shape of the fixing block 56 allows it to divert and comb the slurry, dividing large streams of slurry into multiple small-flow slurry bundles, which have good impact resistance and prevent damage from the impact generated by the slurry flow.

[0046] As a further implementation of this solution, the connecting pipe assembly 6 includes two rigid pipes 61, with an elastic rubber tube 62 bonded and fixed between them. A support ring 63 is fixedly connected through the elastic rubber tube 62, and a metal elastic spring strip 64 is fixedly connected through the inner side of the support ring 63. A magnetic sliding ring 65 is sleeved on the outer side of the rigid pipe 61, and an elastic telescopic tube 66 is slidably connected to the inner side of the rigid pipe 61. One end of the elastic telescopic tube 66 is bonded with a rubber ring 67, and a magnetic plate 68 is fixedly connected to the inner side of the elastic telescopic tube 66. The vertical cross-section of the elastic telescopic tube 66 is "L"-shaped. The magnetic plate 68 and the magnetic sliding ring 65 are magnetically attracted to each other, and the metal elastic spring strip 64 faces away from the elastic... One side of the rubber tube 62 is attached to the outside of the elastic telescopic tube 66. The magnetic sliding ring 65 is arc-shaped on the side near the rigid tube 61. When the slurry flows through the rigid tube 61 and the elastic rubber tube 62, firstly, due to the special design of the vertical section of the elastic telescopic tube 66, one end of the elastic telescopic tube 66 will be impacted by the slurry and slide within the rigid tube 61 and the elastic rubber tube 62. When the end of the elastic telescopic tube 66 with the rubber ring 67 is attached comes into contact with the other components and is obstructed, the elastic telescopic tube 66 will contract to a certain extent, so that the outside of the elastic telescopic tube 66 no longer obstructs part of the inside of the elastic rubber tube 62, and the contraction of the elastic telescopic tube 66 is affected by the density of the slurry. The size of the unobstructed portion inside the elastic hose 62 varies depending on the degree and flow rate. Simultaneously, the magnetic plate 68 fixed inside the elastic telescopic tube 66 generates a magnetic attraction force on the magnetic sliding ring 65, causing the magnetic sliding ring 65 to slide outside the rigid tube 61 and the elastic hose 62. The elastic hose 62, bonded and fixed between the two rigid tubes 61, effectively absorbs axial and radial displacement. When the slurry passes through rapidly, it better withstands the pipeline pressure during slurry transportation. Furthermore, when its diameter changes, multiple support rings 63 approach each other, and the metal elastic spring strip 64 deforms, providing radial support, thereby... The rapid expansion of the pipe path cross-section not only meets the strength requirements of high-pressure transmission conditions but also buffers pressure impacts. The deformation of the metal elastic spring 64 supports the radial expansion of the elastic hose 62 and restricts the return movement of the magnetic sliding ring 65. Therefore, the magnetic sliding ring 65 uses the magnetic attraction of the magnetic plate 68 to keep the elastic telescopic tube 66 stably positioned between the rigid tube 61 and the elastic hose 62. After the slurry absorption operation is completed, the magnetic sliding ring 65 is pulled to squeeze the elastic hose 62 and the metal elastic spring 64, allowing them to recover their deformation. Through its own reset, it drives the magnetic plate 68 and the elastic telescopic tube 66 fixed to the magnetic plate 68 to reset.

[0047] A method for using a pressure slurry filling tank to prevent seal failure: First, install and fix the gas tank 47 to the horizontal pipe 46 with bolts. Next, connect the flange at the upper end of the riser 41 to the flange at the bottom end of the rotary valve 43. Then, connect the feed pipe 53 to the fixed ball valve 52 with a flange. Next, connect the fixed ball valve 52 to the reducer 51 with a flange. Insert the hollow elastic ball 54 into the reducer 51. Finally, connect the reducer 51 to the rigid pipe 61 with a flange and rotate the rotary rod 48. 7. The rotating rod 487 drives the screw 484 to rotate in the adjusting member 486 and cause relative displacement between them. As the screw 484 moves, it pushes the piston disc 488 to slide in the horizontal tube 46. The piston disc 488 drives the magnetic ring 489 to move closer to the magnetic block 454, magnetically pulling the magnetic block 454 out of the valve stem 44 and locking it below the limit ring 42. The air valve on the air tank 47 controls the air tank 47 to fill the riser tube 41 and the horizontal tube 46 with air. The pressure generated by the filled gas acts on the piston disc 488. After overcoming the tension required for the deformation of the tension spring 485, the piston disc 488 slides in the horizontal tube 46, causing the magnetic ring 489 to move. After the magnetic ring 489 moves a certain distance, the magnetic attraction on the magnetic block 454 weakens. Under the force generated by the return spring 453 restoring its deformation, the magnetic block 454 slides along the short rod 452 back into the valve stem 44. Then, the rotary valve 43 is rotated, causing the valve stem 44 to move upward. The gas inside the horizontal tube 46 and the vertical tube 41 is filled into the tank 2, making the gas inside the tank 2... The internal air pressure quickly reaches equilibrium with the external air pressure; the connecting pipe assembly 6 is connected to the pipe that connects to the slurry, and then the air tank 47 is controlled to evacuate the inside of the tank 2. The extracted gas enters the air tank 47 after passing through the riser pipe 41 and the horizontal pipe 46, and then flows out from the exhaust port on the air tank 47. At the same time as the gas inside the tank 2 is discharged, the fixed ball valve 52 is opened to connect the reducer pipe 51, the feed pipe 53 and the inside of the tank 2. The tank 2 will extract the slurry through the slurry suction pipe assembly 5 and the connecting pipe assembly 6.

6. A pressure slurry filling tank for preventing seal failure according to claim 5, characterized in that: The connecting tube assembly (6) includes two rigid tubes (61), and an elastic tube (62) is bonded and fixed between the two rigid tubes (61). A support ring (63) is fixedly connected through the elastic tube (62). A metal elastic spring strip (64) is fixedly connected through the inner side of the support ring (63). A magnetic sliding ring (65) is sleeved on the outer side of the rigid tube (61). An elastic telescopic tube (66) is slidably connected to the inner side of the rigid tube (61). A rubber ring (67) is bonded to one end of the elastic telescopic tube (66). A magnetic plate (68) is fixedly connected to the inner side of the elastic telescopic tube (66).

7. A pressure slurry filling tank for preventing seal failure according to claim 6, characterized in that: The vertical cross section of the elastic telescopic tube (66) is "L" shaped. The magnetic plate (68) and the magnetic sliding ring (65) are magnetically attracted to each other. The side of the metal elastic spring strip (64) facing away from the elastic rubber tube (62) is attached to the outside of the elastic telescopic tube (66). The side of the magnetic sliding ring (65) near the rigid tube (61) is arc-shaped.

8. The method of using a pressure slurry filling tank for preventing seal failure as described in claim 7, characterized in that: S1: First, install and fix the gas tank (47) and the horizontal pipe (46) with bolts. Then, connect the flange at the upper end of the vertical pipe (41) to the flange at the bottom end of the rotary valve (43). Next, connect the feed pipe (53) to the fixed ball valve (52) with a flange. Then, connect the fixed ball valve (52) to the reducer (51) with a flange. Insert the hollow elastic ball (54) into the reducer (51). Finally, connect the reducer (51) to the rigid pipe (61) with a flange. S2: Rotate the rotary rod (487) to drive the screw (484) to rotate in the adjusting member (486) and make relative displacement with the adjusting member (486). While the screw (484) moves, it pushes the piston disc (488) to slide in the horizontal tube (46). The piston disc (488) drives the magnetic ring (489) to move closer to the magnetic block (454), and magnetically pulls the magnetic block (454) out of the valve stem (44) and locks it below the limiting ring (42). The air valve on the air tank (47) controls the air tank (47) to fill the riser (41) and the horizontal tube (46) with air. The pressure generated by the filled gas acts on the piston disc (489). 8) After overcoming the tension required for the deformation of the tension spring (485), the piston disc (488) slides in the horizontal tube (46) and drives the magnetic ring (489) to move. After the magnetic ring (489) moves a certain distance, the magnetic attraction force on the magnetic block (454) weakens. Under the force generated by the return spring (453) to restore the deformation, the magnetic block (454) slides along the short rod (452) and returns to the valve stem (44). Then, the rotary valve (43) is rotated to drive the valve stem (44) to move upward. The gas inside the horizontal tube (46) and the vertical tube (41) is filled into the tank (2), so that the gas pressure inside the tank (2) quickly reaches equilibrium with the external gas pressure. S3: Connect the connecting pipe assembly (6) to the pipe that connects the slurry, and then control the air tank (47) to evacuate the inside of the tank (2). The extracted gas enters the air tank (47) after passing through the riser (41) and the horizontal pipe (46), and then flows out from the exhaust port on the air tank (47). At the same time as the gas inside the tank (2) is discharged, open the fixed ball valve (52) to connect the reducer (51) and the feed pipe (53) with the inside of the tank (2). The tank (2) will extract the slurry through the slurry suction pipe assembly (5) and the connecting pipe assembly (6).
