A dyeing and printing sludge solidification equipment

Abstract

This invention belongs to the field of environmental engineering technology, specifically a dyeing and printing sludge solidification device. It includes a working component, with a pressure probe at the bottom of the inner wall of the working component and a control rod at the axis of the inner cavity. The working component includes a main cylinder shell, with symmetrically rotating docking shells on both sides of the axis of the outer surface of the main cylinder shell. During operation, the device disperses the sludge using convex stirring plates on both sides, and then sprays a solidifying agent through a connecting nozzle inside the sludge. After operation, sludge adheres to the outer surface of the connecting nozzle, and this sludge mixes with the solidifying agent remaining on the inner wall of the nozzle, forming clumps that can clog the nozzle. Therefore, after operation, an external flushing tank cleans the connecting nozzle from the inside out to remove the residual solidifying agent inside and the sludge adhering to the outer surface, preventing the clumps of sludge from clogging the nozzle opening and causing a decrease in the spraying effect.

Description

Technical Field

[0001] This invention belongs to the field of environmental engineering technology, specifically a solidification device for dyeing and printing sludge. Background Technology

[0002] The main purpose of sludge treatment is to reduce the amount of sludge and stabilize it, facilitating its transportation and final disposal. Sludge treatment can reduce its moisture content, changing it from a fluid to a solid state, thus reducing its volume; it can also stabilize organic matter, making it less prone to decay and preventing secondary pollution to the environment.

[0003] In-situ silt solidification technology involves solidifying existing silt on-site without excavating or transporting it. A solidifying agent is evenly sprayed into the silt using a rotating mixing head. However, because the mixing head needs to penetrate deep into the ground to complete the spraying and mixing work, a large amount of sludge easily adheres to its outer surface. When the mixing head stops working, the adhered sludge may solidify at the nozzle, causing the nozzle to become clogged and making spraying difficult. Therefore, improvements are needed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention to solve its technical problems is: a dyeing and printing sludge solidification device, comprising a working component, wherein a pressure probe is provided at the bottom of the inner wall of the working component, and a control rod is provided at the axial center of the inner cavity of the working component;

[0005] The working component includes a main cylinder shell. Symmetrical docking shells are located on the left and right sides of the axial center of the outer surface of the main cylinder shell. Control push plates are evenly arranged on the left and right sides of the inner cavity of the main cylinder shell. An arc-shaped insert plate is slidably connected to the inner cavity of the control push plate via a connecting rod. Flow-transferring components are symmetrically arranged on the left and right sides of the axial center of the inner wall of the main cylinder shell. The control push plates can push the arc-shaped insert plate out of the diameter of the main cylinder shell, thereby achieving a docking effect to restrict the flow-transferring components. Spraying components are symmetrically arranged on the left and right sides of the outer surface of the main cylinder shell.

[0006] The transfer component includes an inner insert cylinder with a mating groove in the middle of its outer surface. A flow-guiding inner groove is formed on the inner cavity of the inner insert cylinder near the main cylinder shell. A guide inner tube is uniformly fixed on the inner cavity of the inner insert cylinder away from the main cylinder shell. An internal push motor is uniformly fixed on the inner wall of the flow-guiding inner groove away from the guide inner tube. A built-in pressure plate is fixedly connected to the top of the output shaft of the internal push motor. As the built-in pressure plate slides along the flow-guiding inner groove, it can further squeeze and discharge the curing agent liquid inside the flow-guiding inner groove from the guide inner tube.

[0007] Furthermore, the spraying component includes an outer rotating shell, with a sleeve nozzle uniformly fixed inside the inner cavity of the outer rotating shell, a convex stirring plate uniformly fixed on the outer surface of the outer rotating shell, a flushing outer box inserted into the axial position of the outer surface of the outer rotating shell, and an insertable inner rod fixedly connected to the axial position of the inner wall of the outer rotating shell. Adaptive insert plates are symmetrically fixed on the outer surface of the insertable inner rod away from the inner insert cylinder. When both the insertable inner rod and the adaptive insert plates are inserted into the axial position of the inner insert cylinder, the end of the guide inner tube can precisely align with the sleeve nozzle.

[0008] Furthermore, the outer surface of the inner insert tube is rotatably connected to the outer surface of the arc-shaped insert plate via a mating groove; the outer surface of the built-in pressure plate is slidably connected to the inner wall of the inner drainage groove; the end of the guide inner tube away from the inner insert tube is pressed against the inner wall of the outer rotating sleeve, and the end of the guide inner tube away from the inner insert tube is mated with the bottom end of the sleeve nozzle. The inner cavity of the outer rotating sleeve is inserted into the inner cavity of the mating outer shell via a plug-in rod; the end of the plug-in inner rod away from the outer rotating sleeve is inserted into the axis of the inner wall of the inner insert tube; and the side of the adapter plate away from the sleeve nozzle is inserted into the axis of the inner wall of the inner insert tube.

[0009] Furthermore, the control rod includes a main motor, with adapter rotating rods fixedly connected to both ends of the main motor's output shaft. A control wire is fixedly connected to the shaft center of the main motor's inner cavity, and a protective shell is fixedly connected to the outer surface of the control wire. Infusion passages are symmetrically fixed on both sides of the outer surface of the protective shell, and a bent tube is fixedly connected to the lower part of the inner cavity of the infusion passage. The strong torque of the main motor drives the inner insert cylinders on both sides to rotate at high speed, and also drives the outer rotating shell to rotate. The shaft center at the top of the main cylinder shell's inner cavity is fixedly connected to the outer surface of the protective shell. The outer surface of the adapter rotating rod is inserted into the inner wall of the inner insert cylinder on the side away from the spraying component. There are two inner insert cylinders, and the output shaft of the main motor is rotatably connected to the inner wall of the inner insert cylinder through the adapter rotating rod. The inner cavity of the inner insert tube is rotatably connected to an independent side shell via a ring groove on the side closest to the main motor. When the inner insert tube rotates, the independent side shell remains stationary due to the restriction of the bent tube, thus becoming a relatively independent shell on the inner insert tube. The bottom of the outer surface of the bent tube is fixedly connected to the inner cavity of the independent side shell through a through-hole, and the end of the bent tube away from the infusion passage extends into the interior of the inner insert tube.

[0010] Furthermore, the pressure sensing component includes an arc-shaped buffer plate. Large grooves are evenly distributed at the bottom of the main cylinder shell's inner cavity, and an inflatable inner belt is evenly fixed to the bottom of the main cylinder shell's inner cavity through these large grooves. The inner wall of the inflatable inner belt is fixedly connected to the outer surface of the arc-shaped buffer plate. When the outer surface of the inflatable inner belt is compressed, the air pressure on its inner wall acts on the pressure-sensing element on the outer surface of the arc-shaped buffer plate. Limiting baffles are symmetrically fixed to the top of the outer surface of the arc-shaped buffer plate, and the outer surface of the limiting baffles is fixedly connected to the outer surface of the main motor. The outer surface of the arc-shaped buffer plate is fixedly connected to the lower part of the inner wall of the main cylinder shell, and the side of the inflatable inner belt away from the arc-shaped buffer plate extends to the outside of the main cylinder shell.

[0011] The beneficial effects of this invention are as follows:

[0012] 1. When the device is in operation, the convex stirring plates on both sides can break up the sludge. Then, a curing agent is sprayed into the sludge through the sleeve nozzle to solidify the sludge. After the device finishes working, sludge will adhere to the outer surface of the sleeve nozzle, and the sludge will mix with the curing agent remaining on the inner wall of the sleeve nozzle and clump together, clogging the sleeve nozzle. Therefore, after the device finishes working, the external flushing tank will clean the residual curing agent inside the sleeve nozzle and the sludge attached to the outer surface from the inside out to prevent the clump of sludge from clogging the opening of the sleeve nozzle and causing the device to deteriorate the spraying effect.

[0013] 2. The working parts, flow conversion parts, and spraying parts of this device are assembled together. Therefore, during maintenance, the outer rotating shell can be removed for individual cleaning and replacement, thus achieving the cleaning of the device. The inner insert cylinder is reinforced by an arc-shaped insert plate, and the outer rotating shell is also reinforced by the insert rod in the inner cavity and the docking shell. The whole is confined to the main cylinder shell, so the stability is higher, avoiding the problem of the assembled device falling apart due to loose connections when rotating.

[0014] 3. When the spraying operation ends, a significant amount of curing agent remains inside the inner channel. At this point, the internal push motor will push the built-in pressure plate to slide along the inner channel, and then the pressurized agent will be further discharged through the inner guide tube, significantly reducing the amount of residual agent inside the working parts. This ensures that the device will not experience severe corrosion due to a large amount of residual curing agent when it is not in operation, thereby extending the service life of the device.

[0015] 4. The bottom of the device is equipped with a pressure-sensing component to help operators perceive the depth of the silt. The greater the reaction force on the arc-shaped buffer plate, the deeper the main cylinder shell is submerged in the silt. Therefore, in order to ensure that the main cylinder shell can rotate normally, the main cylinder shell should not be submerged in the silt at a depth that is too deep or too shallow. This allows the operator to control the device at a suitable position so that the device can carry out normal curing work. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0026] Example 1, please refer to Figures 1-6 The present invention provides a technical solution: a printing and dyeing sludge solidification device, including a working part 1, a pressure probe 2 is provided at the bottom of the inner wall of the working part 1, and a control rod 3 is provided at the axis of the inner cavity of the working part 1;

[0027] The working component 1 includes a main cylinder shell 11. The outer surfaces of the main cylinder shell 11 are symmetrically rotated with docking shells 12 on the left and right sides at the axis. The inner cavity of the main cylinder shell 11 is evenly provided with control push plates 13 on the left and right sides. The inner cavity of the control push plates 13 is slidably connected with arc-shaped insert plates 14 through connecting rods. The inner walls of the main cylinder shell 11 are symmetrically provided with flow transfer components 4 on the left and right sides at the axis. The control push plates 13 can push the arc-shaped insert plates 14 out of the diameter of the main cylinder shell 11, thereby achieving the insertion effect to restrict the flow transfer components 4. The outer surfaces of the main cylinder shell 11 are symmetrically provided with spraying components 5 on the left and right sides.

[0028] The transfer component 4 includes an inner insert cylinder 41. A docking groove 42 is provided in the middle of the outer surface of the inner insert cylinder 41. A flow guide groove 43 is provided on the side of the inner cavity of the inner insert cylinder 41 near the main cylinder shell 11. A guide inner tube 47 is uniformly fixed on the side of the inner cavity of the inner insert cylinder 41 away from the main cylinder shell 11. An inner push motor 45 is uniformly fixed on the inner wall of the flow guide groove 43 away from the guide inner tube 47. The top of the output shaft of the inner push motor 45 is fixedly connected to a built-in pressure plate 46. During the process of the built-in pressure plate 46 sliding along the flow guide groove 43, the curing agent liquid inside the flow guide groove 43 can be further squeezed out from the guide inner tube 47.

[0029] The spraying component 5 includes an outer rotating shell 51, with a sleeve nozzle 56 uniformly fixed inside the outer rotating shell 51. A convex stirring plate 52 is uniformly fixed on the outer surface of the outer rotating shell 51. A flushing outer box 57 is inserted into the center of the outer surface of the outer rotating shell 51. An insert rod 54 is fixedly connected to the center of the inner wall of the outer rotating shell 51. Adaptive insert plates 55 are symmetrically fixed on the outer surface of the insert rod 54 away from the inner insert cylinder 41. When both the insert rod 54 and the adaptive insert plate 55 are inserted into the center of the inner insert cylinder 41, the end of the guide tube 47 can be precisely aligned with the sleeve nozzle 56.

[0030] The outer surface of the inner insert tube 41 is rotatably connected to the outer surface of the arc-shaped insert plate 14 via the mating groove 42. The outer surface of the built-in pressure plate 46 is slidably connected to the inner wall of the inner drainage groove 43. The end of the guide inner tube 47 away from the inner insert tube 41 is pressed against the inner wall of the outer rotating sleeve 51, and the end of the guide inner tube 47 away from the inner insert tube 41 is connected to the bottom end of the sleeve nozzle 56. The inner cavity of the outer rotating sleeve 51 is inserted into the inner cavity of the docking outer shell 12 via the insertion rod 53. The end of the insertion inner rod 54 away from the outer rotating sleeve 51 is inserted into the axis of the inner wall of the inner insert tube 41. The side of the adapter plate 55 away from the sleeve nozzle 56 is inserted into the axis of the inner wall of the inner insert tube 41.

[0031] The control main rod 3 includes a main motor 31. Both ends of the output shaft of the main motor 31 are fixedly connected to adapter rods 32. A control wire 34 is fixedly connected to the shaft center inside the main motor 31. A protective shell 33 is fixedly connected to the outer surface of the control wire 34. Infusion passages 35 are symmetrically fixed on both sides of the outer surface of the protective shell 33. A bent tube 36 is fixedly connected to the lower part of the inner cavity of the infusion passage 35. The strong torque of the main motor 31 drives the inner insert cylinders 41 on both sides to rotate at high speed, and also drives the outer rotating sleeve 51 to rotate. The shaft center at the top of the inner cavity of the main cylinder shell 11 is fixedly connected to the outer surface of the protective shell 33. The outer surface of the adapter rod 32 is inserted into the inner wall of the inner insert cylinder 41 on the side away from the spraying component 5. There are two inner insert cylinders 41. The output shaft of the main motor 31 is rotatably connected to the inner wall of the inner insert cylinder 41 through the adapter rod 32. An independent side shell 44 is rotatably connected to the inner cavity of the inner insert tube 41 near the main motor 31 through an annular groove. When the inner insert tube 41 rotates, the independent side shell 44 remains stationary due to the restriction of the bent tube 36, thus becoming a relatively independent shell on the inner insert tube 41. The bottom of the outer surface of the bent tube 36 is fixedly connected to the inner cavity of the independent side shell 44 through a through-hole, and the end of the bent tube 36 away from the infusion passage 35 extends into the interior of the inner insert tube 41.

[0032] Before using this device to solidify silt, assemble the device first, then connect the control rod 3 to the large equipment. The large equipment will then control the device to operate. The specific operation is as follows:

[0033] The main motor 31 at the bottom is powered by the main control rod 3. The main motor 31 then drives the inner insert cylinder 41 to rotate axially via the adapter rotating rods 32 on both sides. Although the arc-shaped insert plate 14 is inserted into the outer surface of the inner insert cylinder 41 through the docking groove 42, since both the docking groove 42 and the arc-shaped insert plate 14 are arc-shaped, they will not affect the normal rotation of the inner insert cylinder 41. When the inner insert cylinder 41 rotates, it will drive the outer rotating shell 51 to rotate through the inserted adapter plate 55. At this time, the convex stirring plate 52 on the outer surface of the outer rotating shell 51 rotates at high speed, thereby breaking up the external sludge.

[0034] The equipment adds curing agent through the infusion passages 35 on both sides. The flow path of the curing agent is as follows: the curing liquid enters the inner channel 43 of the inner insert tube 41 through the bent pipe 36, and is sprayed out through the guide inner tube 47 under the action of hydraulic pressure. At this time, the insertion action of the adapter plate 55 ensures that the nozzle of the guide inner tube 47 is connected with the socket nozzle 56. Therefore, the socket nozzle 56 will spray the curing agent onto the externally dispersed sludge and inside the sludge.

[0035] After the curing process is completed, the plug rod 53 inserted into the docking housing 12 is pulled outwards, but the plug rod 53 is not separated from the docking housing 12. At this time, the adapter plate 55 will slide out from the axis of the inner plug tube 41, but the plug rod 54 will remain inside the inner plug tube 41. At this time, the outer rotating housing 51 will rotate relative to the inner plug tube 41, and then the guide inner tube 47 will be completely misaligned with the socket nozzle 56. At this time, the outer flushing box 57 will flush the inside of the outer rotating housing 51 with clean water. Since the end of the guide inner tube 47 is blocked by the inner wall of the outer rotating housing 51, the clean water inside the outer rotating housing 51 will be sprayed out through the socket nozzle 56, thereby rinsing the sludge on the outer surface of the socket nozzle 56. Before the sludge has solidified, the sludge residue and the hardener residue on the inner wall are cleaned away, thereby avoiding the problem of sludge clumping at the socket nozzle 56.

[0036] When the spraying operation ends, there is still a lot of curing agent remaining inside the inner channel 43. At this time, the inner push motor 45 will push the built-in pressure plate 46 to slide along the inner channel 43, and then the pressurized agent will be further discharged through the inner guide tube 47, so that the agent content remaining inside the working part 1 is greatly reduced.

[0037] Example 2, please refer to Figures 1-8This invention provides a technical solution: Based on embodiment 1, the pressure sensing component 2 includes an arc-shaped buffer plate 21. Large grooves are uniformly cut at the bottom of the inner cavity of the main cylinder shell 11, and an inflatable inner belt 23 is uniformly fixed to the bottom of the inner cavity of the main cylinder shell 11 through the large grooves. The inner wall of the inflatable inner belt 23 is fixedly connected to the outer surface of the arc-shaped buffer plate 21. When the outer surface of the inflatable inner belt 23 is compressed, the air pressure on its inner wall acts on the pressure-sensing element on the outer surface of the arc-shaped buffer plate 21. Limiting baffles 22 are symmetrically fixed to the top of the outer surface of the arc-shaped buffer plate 21, and the outer surface of the limiting baffles 22 is fixedly connected to the outer surface of the main motor 31. The outer surface of the arc-shaped buffer plate 21 is fixedly connected to the lower part of the inner wall of the main cylinder shell 11, and the side of the inflatable inner belt 23 away from the arc-shaped buffer plate 21 extends to the outside of the main cylinder shell 11.

[0038] When the device is in operation, the bottom of the main cylinder shell 11 needs to be submerged in the silt. At this time, the silt will exert a reaction force on the inflatable inner belt 23 at the bottom. In turn, by pressing the inflatable inner belt 23, the internal arc-shaped buffer plate 21 is triggered. The greater the pressing force, the deeper the main cylinder shell 11 is submerged in the silt. Therefore, in order to ensure that the main cylinder shell 11 can rotate normally, the main cylinder shell 11 should not be submerged too deeply or too shallowly. At this time, the real-time position of the main cylinder shell 11 can be adjusted by the pressure feedback from the arc-shaped buffer plate 21, thereby ensuring that the personnel operating heavy equipment can control the normal movement of the main cylinder shell 11.

[0039] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
