Description

[0001] This invention relates to the field of sludge backfill agent production technology, specifically to a sludge backfill agent production equipment. Background Technology

[0002] Papermaking backfill agent, also known as sludge backfill agent, is a new type of inorganic polymer water purification agent synthesized based on polyphosphate ferric sulfate and polyaluminum ferric sulfate.

However, the raw materials are easily not mixed sufficiently, which leads to backfilling agent powder settling at the bottom of the mixed raw material solution. Insufficient mixing also causes the backfilling agent to clump together, requiring a long time to mix the raw materials completely, which affects the production efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a sludge backfill agent production equipment to solve the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a sludge backfilling agent production equipment, including a fixed bottom, a lifting frame fixedly connected to the top of the fixed bottom, a lifting threaded rod movably connected inside the lifting frame, a movable cover provided at the bottom of the lifting threaded rod, a mixing container provided at the bottom of the movable cover, a stirring mechanism fixedly connected to the bottom of the movable cover, and a ventilation mechanism fixedly connected to the top of the movable cover. The stirring mechanism includes: A stirring motor, which is fixedly connected to the top of the movable cover; A stirring threaded rod is located at the bottom of the movable cover inside the mixing container, and the stirring threaded rod is fixedly connected to the output shaft of the stirring motor. A stirring rack is fixedly connected to the bottom of the stirring thread rod.

[0005] Preferably, a lifting motor is fixedly connected to the top of the lifting frame, a lifting rod is fixedly connected to the bottom output shaft of the lifting motor, the lifting rod is movably connected to a lifting threaded rod, and the bottom of the lifting threaded rod is fixedly connected to the top of the stirring motor.

[0006] Preferably, the mixing container is provided with a partition mesh inside, a guide plate is fixedly connected to the outside of the partition mesh, a guide protrusion is provided on the inner wall of the mixing container, the guide plate is movably connected to the inner wall of the mixing container through the guide protrusion, and the partition mesh is movably connected to the stirring threaded rod.

[0007] Preferably, an internal motor is fixedly connected to the bottom of the separator, and an agitator blade is fixedly connected to the top of the internal motor at the top of the separator.

[0008] Preferably, two connecting pipes are fixedly connected to the outer wall of the mixing container, and both ends of the connecting pipes are fixedly connected to the outer wall of the mixing container.

[0009] Preferably, the ventilation mechanism includes an air inlet pipe, which is fixedly connected to the top of the movable cover, and an exhaust pipe is fixedly connected to the top of the movable cover.

[0010] Preferably, the mixing container has a corresponding notch at the bottom of the intake pipe, the bottom of the movable cover is movably connected to an intake plug at the bottom of the intake pipe, the mixing container has a corresponding notch at the bottom of the exhaust pipe, and the top of the movable cover is movably connected to an exhaust plug at the bottom of the exhaust pipe.

[0011] Preferably, a movable plate is movably connected inside the mixing container, and a vent hole is provided on the movable plate. A push rod is fixedly connected to the top of the guide plate, and the push rod is movably connected to the movable plate. A lower protrusion is fixedly connected to the outer wall of the push rod at the bottom of the movable plate, and an upper protrusion is fixedly connected to the outer wall of the push rod at the top of the movable plate.

[0012] This invention provides a sludge backfill agent production equipment. It has the following beneficial effects: 1. This sludge backfill agent production equipment uses a stirring motor to drive a stirring frame for stirring, while simultaneously moving a separator screen up and down inside the mixing container. This increases the contact area between the raw material deposited on top of the separator screen and the liquid, thereby promoting the dissolution of the raw material and pushing the liquid through the connecting pipe to further dissolve the raw material into the solution, thus improving the production efficiency of the sludge backfill agent.

[0013] 2. This sludge backfill agent production equipment is driven by a movable plate, which causes the pressure in the space above the movable plate to change cyclically. This allows outside air to enter through the air inlet plug and be discharged to the outside through the air outlet plug, thus achieving air circulation inside the mixing container. This provides oxygen for the oxidation reaction during the mixing process and avoids the reaction rate from decreasing due to insufficient oxygen, which would affect the production efficiency of the sludge backfill agent.

[0014] 3. In this sludge backfill agent production equipment, the guide plate drives the movable plate to move down, which compresses the air at the top of the liquid surface before the vent moves to the connecting pipe. The compressed air can heat the air and heat the liquid surface. Heating can accelerate the reaction speed, improve the efficiency of raw material dissolution and mixing, and improve the production efficiency of sludge backfill agent.

[0015] 4. In this sludge backfill agent production equipment, the guide plate drives the movable plate to move upward. The air at the bottom of the movable plate 61 is pulled up, which reduces the pressure at the top of the liquid. This causes the dissolved air in the liquid to expand and precipitate out of the liquid. The upward-discharged air bubbles can stir the liquid, improve the mixing efficiency of the raw materials, and thus improve the production efficiency of the sludge backfill agent.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0020] Example 1: Please refer to Figure 1-6 The present invention provides a technical solution: a sludge backfill agent production equipment, including a fixed base 1, a lifting frame 2 fixedly connected to the top of the fixed base 1, a lifting threaded rod 22 movably connected inside the lifting frame 2, a movable cover 4 provided at the bottom of the lifting threaded rod 22, a mixing container 3 provided at the bottom of the movable cover 4, a stirring mechanism 5 fixedly connected to the bottom of the movable cover 4, a ventilation mechanism 6 fixedly connected to the top of the movable cover 4, and a locking structure provided at the top of the fixed base 1, which can fix the mixing container 3 on the top of the fixed base 1; The stirring mechanism 5 includes: The stirring motor 51 is fixedly connected to the top of the movable cover 4; The stirring threaded rod 52 is located at the bottom of the movable cover 4 inside the mixing container 3, and is fixedly connected to the output shaft of the stirring motor 51. The stirring rack 53 is fixedly connected to the bottom of the stirring threaded rod 52.

[0021] A lifting motor 21 is fixedly connected to the top of the lifting frame 2. A lifting rod 23 is fixedly connected to the bottom output shaft of the lifting motor 21. The lifting rod 23 is movably connected to the lifting threaded rod 22. The bottom of the lifting threaded rod 22 is fixedly connected to the top of the stirring motor 51.

[0022] First, water used for backfilling is injected into the mixing container 3, and some raw materials are added into the mixing container 3. Then, the lifting motor 21 drives the lifting rod 23 to rotate, causing the lifting threaded rod 22 to push the stirring motor 51 downward, so that the movable cover 4 covers the top of the mixing container 3. After the movable cover 4 covers the top of the mixing container 3, the stirring motor 51 drives the stirring threaded rod 52 to rotate, causing the stirring frame 53 to rotate, stirring the inside of the mixing container 3 and promoting the mixing of raw materials. At the same time, when new raw materials need to be added later, the stirring motor 51 stops driving the stirring threaded rod 52 to rotate, and the lifting motor 21 drives the lifting rod 23 to rotate in the opposite direction, so that the lifting threaded rod 22 drives the movable cover 4 upward through the stirring motor 51, thereby facilitating the addition of raw materials into the mixing container 3. After the addition is completed, the lifting motor 21 drives the lifting rod 23 to rotate again, so that the movable cover 4 covers the top of the mixing container 3.

[0023] The raw materials added to the mixing container 3 are moved within the mixing container 3 to improve dissolution efficiency and prevent the raw materials from clumping at the bottom. A partition mesh 54 is provided inside the mixing container 3, and a guide plate 55 is fixedly connected to the outside of the partition mesh 54. A guide protrusion 56 is provided on the inner wall of the mixing container 3. The guide plate 55 is movably connected to the inner wall of the mixing container 3 through the guide protrusion 56, and the partition mesh 54 is movably connected to the stirring threaded rod 52.

[0024] After the raw materials are added into the mixing container 3, the unmixed raw materials will move towards the bottom of the mixing container 3 until they fall onto the top of the separator 54. When the stirring motor 51 drives the stirring frame 53 to rotate through the stirring threaded rod 52 to stir the inside of the mixing container 3, it can also push the separator 54 to move up and down inside the mixing container 3 through the threads on the outer wall of the stirring threaded rod 52. This allows the stirring motor 51 to drive the stirring threaded rod 52 to rotate back and forth in two directions, which can make the separator 54 move up and down inside the mixing container 3, increase the contact area between the raw materials and the liquid at the top of the separator 54, and thus promote the dissolution of the raw materials.

[0025] Agitating the raw materials accumulated at the top of the separator 54 can promote the blending of the raw materials. An internal motor 57 is fixedly connected to the bottom of the separator 54, and an agitator blade 58 is fixedly connected to the top of the internal motor 57 at the top of the separator 54.

[0026] After the undissolved raw material falls to the top of the separator 54, the internal motor 57 drives the stirring blade 58 to rotate, causing the stirring blade 58 to rotate. At the same time, the stirring blade 58 is also inclined, which can push the liquid at the bottom of the separator 54 upward, so that the liquid carries the undissolved raw material upward and disperses it, making it easier for the raw material to mix with the liquid.

[0027] Excessive raw material accumulation on the separator 54 will reduce the liquid flowability of the separator 54, resulting in increased resistance when the separator 54 moves. Therefore, it is necessary to prevent the separator 54 from deforming or being damaged due to excessive resistance during movement. Two connecting pipes 59 are fixedly connected to the outer wall of the mixing container 3, and both ends of the connecting pipes 59 are fixedly connected to the outer wall of the mixing container 3.

[0028] When the separator 54 moves upward, it will pull up the liquid at the bottom of the separator 54, reducing the pressure of the liquid at the bottom of the separator 54. At the same time, the liquid at the top of the separator 54 will be pushed upward, causing some of the liquid at the top of the separator 54 to move to the bottom of the mixing container 3 through the connecting pipe 59, thereby balancing the force on part of the separator 54.

[0029] Meanwhile, the liquid mixed with the raw materials at the top of the separator 54 can flow more easily to the bottom of the separator 54, further promoting the mixing between the raw materials.

[0030] Example 2: Please refer to Figure 1-8 Based on Embodiment 1, the present invention provides a technical solution: The mixing of raw materials involves oxidation-reduction reactions. When the oxygen content in the air is low, it cannot effectively provide oxidants for the reaction, resulting in a slow reaction efficiency and reduced production efficiency of the backfill agent.

[0031] Increasing the gas flow efficiency in the mixing container 3 can replenish the oxygen consumed in the container in a timely manner, thereby avoiding a decrease in reaction efficiency due to insufficient oxygen. The ventilation mechanism 6 includes an air inlet pipe 62, which is fixedly connected to the top of the movable cover 4. An exhaust pipe 63 is fixedly connected to the top of the movable cover 4.

[0032] The mixing container 3 has a corresponding notch at the bottom of the intake pipe 62, and the bottom of the movable cover 4 is movably connected to the intake plug 64 at the bottom of the intake pipe 62. The mixing container 3 has a corresponding notch at the bottom of the exhaust pipe 63, and the top of the movable cover 4 is movably connected to the exhaust plug 65 at the bottom of the exhaust pipe 63.

[0033] The movable plate 61 is driven to move up and down inside the mixing container 3, causing the space between the top of the movable plate 61 and the movable cover 4 to continuously increase and decrease. This causes the pressure in the space at the top of the movable plate 61 to change cyclically. During this process, when the pressure decreases, the external air pressure pushes the air inlet plug 64 downward to enter the mixing container 3. When the pressure increases, the internal air pressure pushes open the exhaust plug 65 to discharge to the outside. The movable plate 61 moves up and down, thereby realizing the function of circulating air inside the mixing container 3 and providing oxygen for the oxidation reaction during the mixing process.

[0034] The mixing container 3 is movably connected to a movable plate 61, which has a vent hole 66. A push rod 67 is fixedly connected to the top of the guide plate 55. The push rod 67 is movably connected to the movable plate 61. A lower protrusion 69 is fixedly connected to the outer wall of the push rod 67 at the bottom of the movable plate 61, and an upper protrusion 68 is fixedly connected to the outer wall of the push rod 67 at the top of the movable plate 61. The vent hole 66 is a small vent hole that allows air to slowly pass through the movable plate 61.

[0035] The stirring motor 51 drives the separator 54 to move up and down via the stirring threaded rod 52, which in turn drives the guide plate 55 to move up and down, and further drives the push rod 67 to move up and down. As the push rod 67 moves upward, it pushes the vent 66 upward through the lower protrusion 69. During this process, the space at the top of the movable plate 61 gradually decreases, while the air pressure at the bottom of the movable plate 61 decreases, causing the dissolved air in the liquid to expand and precipitate out of the liquid. The upward-discharged air bubbles in the liquid can stir the liquid. When the movable plate 61 reaches its highest point, the pressure at the top and bottom of the movable plate 61 gradually balances through the small holes in the vent 66. Subsequently, the guide plate 55 is driven downward, causing the upper protrusion 68 to pull the movable plate 61 downward. At this point, the pressure at the bottom of the movable plate 61 increases, while the pressure at the top decreases. Before the vent 66 moves to the connecting pipe 59, the air at the top of the liquid surface is compressed. This compression heats the air, which in turn heats the liquid surface, accelerating the reaction. When the separator 54 moves to the bottom, the air pressure at the top and bottom of the movable plate 61 gradually balances through the vent 66. Simultaneously, as the air at the bottom of the movable plate 61 is compressed, the stirring blades 58 push the liquid upward, causing the liquid surface to churn and further promoting the mixing of air into the liquid. At the same time, the separator 54 pushes some liquid through the connecting pipe 59, further increasing the contact area between the liquid and air, allowing air to pass through the mixed liquid and improving the reaction efficiency.

[0036] 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.
