Description

Technical Field

[0001] The invention relates to the technical field of centrifuges, in particular to a horizontal spiral screen centrifuge. Background Art

[0002] The horizontal spiral screen centrifuge is a highly efficient solid-liquid separation equipment. It is placed horizontally and uses a motor to drive the drum to rotate at high speed to generate a strong centrifugal force, so that the liquid in the mixed material passes through the cone filter and is quickly separated, while the solid particles are trapped on the screen. The spiral pusher in the drum continuously pushes the trapped solid particles to the discharge port for discharge, thereby achieving a continuous and efficient solid-liquid separation process. It is widely used in chemical, environmental protection, food, pharmaceutical and other industries.

[0003] When existing horizontal spiral screen centrifuges are used to centrifuge solids and liquids, the solids gradually agglomerate as the centrifugal force increases over time, making it impossible to completely separate the solids and liquids. This is because under the action of long-term centrifugal force, the centrifugal force on the solid particles continues to increase, and the relative movement between the particles intensifies. On the one hand, the particles frequently collide during high-speed motion, and these collisions give the intermolecular forces on the particle surface (such as van der Waals forces) more opportunities to take effect, causing the particles to adsorb and approach each other. On the other hand, as the centrifugal force increases, the flow rate of the liquid accelerates, the ability to carry and disperse solid particles decreases, the dispersion stability of the solid particles in the liquid deteriorates, and they are more likely to aggregate together, resulting in increasingly obvious agglomeration. This agglomeration not only causes part of the liquid to be wrapped inside the solid agglomerates, making it difficult to separate them through the screen, but also clogs the screen, further hindering solid-liquid separation, and ultimately making it impossible to completely separate the solid and liquid, affecting the separation effect and the operating efficiency of the equipment. Summary of the Invention

[0004] In response to the above-mentioned shortcomings of the prior art, the present invention provides a horizontal spiral screen centrifuge, which can effectively solve the problem in the prior art that particles frequently collide during high-speed movement, resulting in part of the liquid being wrapped inside the solid agglomerates, making it difficult to separate through the screen and also clogging the screen.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] The present invention provides a horizontal spiral screen centrifuge, comprising:

[0007] A base, the outer surface of which is fixedly connected to a support seat;

[0008] The screening mechanism includes a protective barrel fixedly connected to the support base, the protective barrel having a feed port and a discharge port, a hatch sealed and hinged on the side of the feed port, a rotating assembly disposed inside the protective barrel, and a filtering assembly disposed inside the rotating assembly;

[0009] The spiral pushing mechanism includes a discharge barrel fixedly connected to the discharge port, a turntable airtightly connected to the other side of the discharge barrel, and the turntable is used to drive the filter assembly to rotate, and a double gear ring is fixedly connected to the other side of the turntable, and a hollow rod is provided at the center position of the turntable facing the discharge barrel. A plurality of inertial telescopic components are provided inside the hollow rod, and two sets of elastic crushing components and a stirring component are provided inside the inertial telescopic component;

[0010] The motor is fixedly connected to the base and is used to drive the turntable to rotate.

[0011] Preferably, the upper end surface of the base located between the two support seats is fixedly connected to a miscellaneous box, the front of the miscellaneous box is fixedly connected to a square pipe for discharging miscellaneous items, a controller is installed on the side of the base, and the controller is electrically connected to the motor;

[0012] The inner circumference of the protective barrel is linearly arrayed with a plurality of annular slide rails fixedly connected thereto, and the bottom linear array of the inner circumference of the protective barrel is provided with a plurality of groups of debris removal holes, and each group of debris removal holes is positioned alternately with the annular slide rails;

[0013] The rotating assembly includes a plurality of first positioning rings and second positioning rings which are sleeved in the inner length direction of the protective barrel. The number of the first positioning rings is one more than the number of the second positioning rings, and the positions of the first positioning rings and the second positioning rings are alternated. The outer peripheral surfaces of the first positioning rings and the second positioning rings are fixedly connected to a plurality of interconnected plates in a common annular array. A plurality of pulleys are fixedly connected to the other side of the interconnected plates in a linear array, and the number and position of the pulleys correspond to the annular slide rails one by one. The pulleys are in rolling engagement with the inner part of the annular slide rails.

[0014] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0015] 1. The solid-liquid separation of the material entering the protective barrel can be achieved through the rotating component, the filtering component and the rebound cleaning component in the screening mechanism. Among them, the rotating component is used to maintain the stability of the filtering component in the protective barrel when it rotates and to provide rotating support for the filtering component. The filtering component realizes the solid-liquid separation of the material through high-speed rotation, so that the solid is retained in the filtering component and the liquid is discharged from the filtering component. When the filtering component separates the solid and liquid of the material, the rebound cleaning component realizes the continuous rebound and crushing of the material. On the one hand, it realizes the position movement of the material in the filtering component, and on the other hand, it realizes the rebound and crushing of the agglomerated material due to centrifugal separation. By continuously moving the material in the filtering component, local accumulation affecting the separation efficiency is avoided, and the agglomeration of the material caused by centrifugal force can be broken, so that the solid particles are dispersed more evenly, and agglomeration is prevented from hindering the liquid from passing through the conical filter mesh, thereby improving the solid-liquid separation effect.

[0016] 2. Through the inertial telescopic component, elastic crushing component and stirring component in the spiral pushing mechanism, the position and shape of the material in the liquid-solid separation process in the filter component can be further changed, and the material that has completed liquid-solid separation in the filter component can be moved for discharge. Among them, when the filter component reaches the maximum speed, the inertial telescopic component extends out of the hollow rod, so that the elastic crushing component and stirring component located therein complete the crushing of the agglomerated material and the change of the direction when the filter component rotates, so as to avoid the material from being concentrated in a unified position in the filter component. The speed of the filter component is increased before liquid-solid separation and reduced after liquid-solid separation. The spiral sheet in the hollow rod is used to move the material, so that the material that has completed liquid-solid separation can enter and discharge smoothly, reduce material residue, and improve the processing capacity and separation quality of the equipment.

[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] The present invention will be further described below with reference to the embodiments.

[0036] Example: Refer to Figures 1 to 15 , a horizontal spiral screen centrifuge, comprising:

[0037] The base 1 has a support base 11 fixedly connected to its outer surface;

[0038] The screening mechanism 2 includes a protective barrel 21 fixedly connected to the support base 11, the protective barrel 21 having a feed port and a discharge port, a hatch 25 sealed and hinged on the side of the feed port, a rotating assembly 22 disposed inside the protective barrel 21, and a filtering assembly 23 disposed inside the rotating assembly 22;

[0039] The spiral pushing mechanism 3 includes a discharge barrel 39 fixedly connected to the discharge port. The other side of the discharge barrel 39 is airtightly connected to a turntable 31, and the turntable 31 is used to drive the filter assembly 23 to rotate. The other side of the turntable 31 is fixedly connected to a double gear ring 32. A hollow rod 33 is provided at the center of the turntable 31 facing the discharge barrel 39. A plurality of inertial telescopic assemblies 36 are provided inside the hollow rod 33. The inertial telescopic assemblies 36 are provided inside. Two sets of elastic crushing assemblies 37 and a stirring assembly 38 are provided inside the inertial telescopic assemblies 36.

[0040] The motor 4 is fixedly connected to the base 1 and is used to drive the turntable 31 to rotate.

[0041] The rotating component 22 in the screening mechanism 2 is used to provide support and rotation guidance for the rotation of the filter component 23 in the protective barrel 21, so that the rotating component 22 can rotate smoothly in the protective barrel 21, and the filter component 23 realizes liquid-solid separation of the material entering therein through the centrifugal force generated by high-speed rotation, and the spiral pushing mechanism 3 transmits the power of the motor 4 to the turntable 31 through the double gear ring 32, so that the turntable 31 further drives the filter component 23 to rotate. The double gear ring 32 transmits power to the turntable 31 and also drives the hollow rod 33 to rotate. After the speed of the filter component 23 reaches the maximum, the inertial telescopic component 36 located in the hollow rod 33 extends, and through the elastic crushing component 37 and the stirring component 38 in the inertial telescopic component 36, the crushing and position change of the material in the separation process are realized.

[0042] Reference Figures 4 to 7 The upper end surface of the base 1 located between the two support seats 11 is fixedly connected to a miscellaneous box 12, and the front of the miscellaneous box 12 is fixedly connected to a square pipe 13 for discharging miscellaneous materials. A controller is installed on the side of the base 1, and the controller is electrically connected to the motor 4;

[0043] The inner circumference of the protective barrel 21 is linearly connected to a plurality of annular slide rails 211. The bottom of the inner circumference of the protective barrel 21 is linearly arranged with a plurality of groups of debris removal holes 212, and each group of debris removal holes 212 is alternately positioned with the annular slide rails 211.

[0044] The rotating assembly 22 includes a plurality of first positioning rings 221 and second positioning rings 222 which are sleeved on the inner length direction of the protective barrel 21. The number of the first positioning ring 221 is one more than the number of the second positioning ring 222, and the positions of the first positioning ring 221 and the second positioning ring 222 are alternated. The outer peripheral surfaces of each first positioning ring 221 and the second positioning ring 222 are fixedly connected to a plurality of interconnecting plates 223 in a common annular array. The other side of the interconnecting plate 223 is fixedly connected to a plurality of pulleys 224 in a linear array, and the number and position of the pulleys 224 correspond one-to-one to the annular slide rail 211, and the pulleys 224 are in rolling engagement with the inner part of the annular slide rail 211.

[0045] By engaging the annular slide rail 211 with the pulley 224 , the first positioning ring 221 and the second positioning ring 222 can rotate along the protective barrel 21 , and the liquid separated by the filter assembly 23 will be discharged into the impurity collection box 12 through the impurity discharge hole 212 along the inner wall of the protective barrel 21 , and then the liquid in the impurity collection box 12 will be discharged through the impurity discharge square pipe 13 .

[0046] Reference Figure 4 、 Figure 8 The filter assembly 23 includes a plurality of connecting rods 232 in an annular array on the inner circumference of the first positioning ring 221, and a plurality of elastic rods 234 are fixedly connected to the inner circumference of the second positioning ring 222 in an annular array. The other side of each connecting rod 232 is commonly fixedly connected to the first spacer ring 231, and the other side of each elastic rod 234 is commonly fixedly connected to the second spacer ring 233. The first spacer ring 231 is larger than the second spacer ring 233. A conical filter screen 235 is fixedly connected between the adjacent first spacer rings 231 and the second positioning ring 222. A plurality of linkage rods 236 are fixedly connected to the side of the first spacer ring 231 near the discharge barrel 39 in an annular array, and the other side of the linkage rod 236 is fixedly connected to the side of the turntable 31 facing the first spacer ring 231.

[0047] A conical filter screen 235 is formed by utilizing the different sizes of the first spacer ring 231 and the second positioning ring 222 in the filter assembly 23, and a linkage rod 236 is used to transmit the power provided by the motor 4 to the turntable 31 to the first spacer ring 231, the second positioning ring 222 and the conical filter screen 235, thereby realizing liquid-solid separation of the material.

[0048] Reference Figures 6 to 9The inner circumference of each first positioning ring 221 and the second positioning ring 222 is provided with a plurality of rebound cleaning components 24 in a common annular array. The rebound cleaning component 24 includes a fixed plate 241 fixedly connected to the inner circumference of the first positioning ring 221 and the second positioning ring 222. The upper end surface of the fixed plate 241 is fixedly connected to a plurality of elastic airbags 242 in a linear array. The bottom of the fixed plate 241 is fixedly connected to a plurality of exhaust pipes 244 corresponding to the elastic airbags 242, and one end of the exhaust pipe 244 close to the elastic airbag 242 passes through the fixed plate 241 and is connected to the elastic airbag 242.

[0049] The upper end surface of the fixed plate 241 is provided with a plurality of counterweight assemblies 243, and the positions of the counterweight assemblies 243 and the elastic airbags 242 are alternating. The counterweight assemblies 243 include an elastic telescopic rod 2431 fixedly connected to the upper end surface of the fixed plate 241. The rod body of the elastic telescopic rod 2431 is slidably connected to a counterweight block 2432. Springs 2433 are symmetrically fixedly connected to the opposite sides of the counterweight block 2432 with the elastic telescopic rod 2431 as the center. The other end of the spring 2433 close to the fixed plate 241 contacts the upper end surface of the fixed plate 241.

[0050] The elastic airbag 242 and the elastic telescopic rod 2431 are fixedly connected to a pressure plate 245 on one side away from the fixed plate 241, and the other end of the spring 2433 close to the pressure plate 245 is in contact with the bottom of the pressure plate 245. The pressure plate 245 is fixedly connected to a plurality of pressure-collecting covers 246 in a linear array on one side away from the elastic airbag 242.

[0051] The pressure-collecting hood 246 in the rebound cleaning component 24 can withstand the inertia of the material in the filter component 23 during centrifugal separation, and guide the inertia into the elastic airbag 242, thereby compressing the elastic airbag 242, the spring 2433, and the counterweight block 2432, so that the gas in the elastic airbag 242 is released through the exhaust pipe 244 to the conical filter screen 235 at the corresponding position to clean the material adhering to the conical filter screen 235.

[0052] Reference Figures 10 to 12 The bottom of the discharge cylinder 39 is fixedly connected to a discharge square tube 391, and the other end of the discharge square tube 391 passes through the base 1 and extends to the bottom of the base 1. The double gear ring 32 has outer ring teeth and inner ring teeth, and the number of outer ring teeth is greater than the number of inner ring teeth;

[0053] The turntable 31 faces one side of the double gear ring 32 and is rotatably connected to the position corresponding to the hollow rod 33 with a rotating shaft 311. The end of the rotating shaft 311 facing the double gear ring 32 is fixedly connected to the power gear 312. The other end of the rotating shaft 311 passes through the turntable 31 and is fixedly connected to the hollow rod 33. The turntable 31 is located between the inner ring of the double gear ring 32 and the power gear 312 and is rotatably connected to the indirect gear 313. The indirect gear 313 meshes with the inner ring teeth of the double gear ring 32 and the power gear 312. The output end of the motor 4 is fixedly connected to a transmission gear, and the transmission gear meshes with the outer ring teeth of the double gear ring 32.

[0054] The rod body of the hollow rod 33 is fixedly connected to the spiral pieces 34 , each inertial telescopic assembly 36 is located between the spiral pieces 34 , and the inner middle portion of the hollow rod 33 is fixedly connected to the fixed rod 35 .

[0055] The motor 4 is engaged with the outer ring teeth of the double gear ring 32, thereby driving the turntable 31 to rotate through the double gear ring 32. Since the number of outer ring teeth of the double gear ring 32 is greater than the number of inner ring teeth, the rotation speed transmitted to the rotating shaft 311 by the indirect gear 313 through the inner ring teeth is lower than that of the turntable 31, so that the rotation speed of the screening mechanism 2 driven by the turntable 31 is higher than the rotation speed of the spiral pushing mechanism 3 driven by the rotating shaft 311.

[0056] Reference Figures 12 to 13 The inertial telescopic assembly 36 includes a yielding telescopic rod 361 fixedly connected to the rod body of the fixed rod 35, and the telescopic end of the yielding telescopic rod 361 is fixedly connected to a sliding frame 362. The sliding frame 362 is slidably connected to the rod wall of the hollow rod 33, and the upper end surface of the sliding frame 362 extends beyond the rod body of the hollow rod 33. The upper end surface of the sliding frame 362 is fixedly connected to at least one counterweight ball 363.

[0057] The yielding telescopic rod 361 in the inertial telescopic assembly 36 is used to achieve the force required for extension by utilizing the inertia of the counterweight ball 363 when the speed of the motor 4 reaches the maximum, so that the yielding telescopic rod 361 can extend from the inside to the outside along the hollow rod 33.

[0058] Reference Figure 13 、 Figure 14The two groups of elastic crushing components 37 are respectively arranged on the inner walls of both sides of the sliding frame 362 in the width direction. Each group of elastic crushing components 37 has multiple, and a rectangular array is arranged on the inner wall of the sliding frame 362. The elastic crushing component 37 includes a fixed seat 371 fixedly connected to the inner wall of the sliding frame 362. The fixed seat 371 is symmetrically fixedly connected to two groups of positioning plates 372 in the length direction away from one side of the sliding frame 362. Each group of positioning plates 372 has at least two. The fixed seat 371 is fixedly connected to a plurality of slideways 374 in the width direction of one side of the positioning plate 372. The upper end surface of each slideway 374 is slidably connected to a slider 375. The lower position on both sides of the slider 375 in the length direction is fixedly connected to a flexible spring 373 corresponding to the positioning plate 372, and the other side of the flexible spring 373 is fixedly connected to the positioning plate 372. The upper position on both sides of the slider 375 in the length direction is fixedly connected to a plurality of crushing knives 376.

[0059] When the elastic crushing assembly 37 is extended, the crushing knife 376 in the elastic crushing assembly 37 is used to break the agglomerates when the solid-liquid materials are separated by centrifugal force, and the flexible spring 373 is used to buffer the slider 375 when the crushing knife 376 breaks the materials.

[0060] Reference Figure 13 、 Figure 15 The stirring assembly 38 includes a rotating rod 381 rotatably connected to both sides of the inner length direction of the sliding frame 362. The rod body of the rotating rod 381 is fixedly connected to two hollow spiral covers 382 in a mirror-image manner. The rod body of the rotating rod 381 is located between the two hollow spiral covers 382 and is rotatably connected to two resistance fan blades 383. A stirring frame 384 is fixedly connected between the fan blades of the two resistance fan blades 383. The stirring frame 384 is composed of multiple inclined blades with different inclinations.

[0061] The collision between the stirring frame 384 and the material is used as the driving force for the rotation of the rotating rod 381, and the hollow spiral cover 382 and the resistance fan 383 are used to realize the change of the motion state of the material during separation.

[0062] The operating principle of this embodiment is as follows:

[0063] Step 1: First, the operator opens the hatch 25 and pours the solid-liquid mixture to be separated into the filter assembly 23 through the feed port of the protective barrel 21, and then closes the hatch 25 (Special note: the hatch 25 is not necessarily closed. The operator can selectively close it based on the liquid content of the solid-liquid mixture and actual conditions. For example, if the liquid content of the solid-liquid mixture is high, it can be closed to prevent splashing during subsequent separation).

[0064] Then, the operator starts the motor 4 through the controller, and the motor 4 starts to run, thereby driving the double gear ring 32 to rotate, so as to provide initial power for the operation of the entire equipment (the equipment in this scheme refers to the horizontal spiral screen centrifuge). Since the number of outer ring teeth of the double gear ring 32 is greater than the number of inner ring teeth, the double gear ring 32 will produce different transmission effects when transmitting power. The double gear ring 32 drives the turntable 31 to rotate, and the turntable 31 drives the filter assembly 23 to rotate at high speed through the linkage rod 236. Since the power of the motor 4 directly acts on the outer ring teeth of the double gear ring 32, the filter assembly 23 can obtain a higher rotation speed, thereby generating a strong centrifugal force to achieve efficient solid-liquid separation.

[0065] Among them, when the turntable 31 drives the filter assembly 23 to rotate at a high speed through the linkage rod 236, the first spacer ring 231, the second spacer ring 233 and the conical filter screen 235 of the filter assembly 23 rotate at a high speed, so that the material to be separated is separated into solid and liquid under the action of a strong centrifugal force. Since the first spacer ring 231 is larger than the second spacer ring 233 and the conical filter screen 235 is conical, the distribution of the material on the filter screen is more uniform, because: the high-speed rotation of the filter assembly 23 generates centrifugal force, so that the material is thrown toward the conical filter screen 235 by this force. Since the material passes through the conical filter screen 235 from the larger first spacer ring 231 to the smaller second spacer ring 233, the radius gradually decreases. According to the centrifugal force formula F=mω 2 r (F is centrifugal force, m is material mass, ω is rotational angular velocity, and r is the distance from the material to the rotation center). The centrifugal force of the material gradually decreases during the movement toward the second spacer ring 233, which prevents the material from being overly concentrated in one place. At the same time, the second spacer ring 233 is connected by an elastic rod 234. Under the inertia of the material, the second spacer ring 233 will swing, driving the conical filter screen 235 connected to it to swing together, thereby effectively shaking off the material adhering to the filter screen, preventing the filter screen from being blocked, and ensuring continuous and efficient filtration. In addition, the elasticity of the elastic rod 234 can also buffer the impact of the centrifugal force generated by the high-speed rotation of the material on the filter screen, protect the filter screen structure, and extend its service life. Moreover, this swing can also make the material more evenly distributed on the filter screen, optimize the filtration effect, allow the liquid to pass through the filter screen more smoothly, and the solid particles are more effectively intercepted, thereby improving the quality of solid-liquid separation.

[0066] Among them, when the filter component 23 rotates at high speed, the rotating component 22 ensures the stable operation of the filter component 23, provides support for the first spacer ring 231 and the second spacer ring 233 through the first positioning ring 221 and the second positioning ring 222, and rolls and engages with the annular slide rail 211 through the pulley 224 in the interconnecting plate 223, like a wheel on a track, to provide stable rotation support for the filter component 23, ensuring that the filter component 23 will not shake, deflect or other unstable phenomena when rotating at high speed, thereby maintaining the stable progress of the solid-liquid separation process.

[0067] Step 2: When the filter assembly 23 separates the solid and liquid materials, the filter assembly 23 and the rebound cleaning assembly 24 work together. As the filter assembly 23 rotates at high speed, the material contacts the pressure collecting cover 246 under the action of centrifugal force. The pressure collecting cover 246 bears the inertia force of the material and pushes the pressure plate 245. The pressure plate 245 squeezes the elastic airbag 242 and the spring 2433, and at the same time drives the counterweight block 2432 to slide on the elastic telescopic rod 2431. The elastic airbag 242 is squeezed, and the internal gas is quickly released to the cone through the exhaust pipe 244. The airflow formed by these gases can effectively blow off the solid particles adhering to the pores and surface of the filter, prevent the filter from being blocked, maintain the permeability of the filter, and ensure the smooth progress of the solid-liquid separation process. At the same time, these gases will also act on the solid particles close to the filter, disrupt the agglomeration structure between the particles, and redisperse the already agglomerated particles. For example, when processing materials containing fine particles, the particles that were originally gathered together due to centrifugal force will be broken up into single or smaller particle clusters after being impacted by the gas.

[0068] Among them, as the filter component 23 continues to rotate, the rebound cleaning component 24 also rotates accordingly. When the rebound cleaning component 24 rotates to the top position of the filter component 23, the inertial force of the material no longer acts on the pressure collecting cover 246. At this time, the counterweight block 2432 slides downward along the elastic telescopic rod 2431 under the combined action of its own gravity and the elastic restoring force of the spring 2433, driving the pressure plate 245 and the elastic airbag 242 to return to their original state. During the recovery process of the elastic airbag 242, air is drawn from the outside through the exhaust pipe 244 to reserve gas for the next cleaning work. The filter component 23 continues to rotate, and the rebound cleaning component 24 repeats this cycle to continuously clean the filter screen.

[0069] Additional explanations are needed:

[0070] During the operation of the horizontal spiral screen centrifuge, when the filter assembly 23 rotates at high speed, the elastic airbag 242 resumes the suction process. Because the strong centrifugal force generated by the filter assembly 23 is much greater than the suction force of the elastic airbag 242, and the material is tightly attached to the conical filter mesh 235, the material will neither be sucked into the elastic airbag 242 nor clog the exhaust pipe 244; before the filter assembly 23 rotates, the rebound cleaning assembly 24 is in a natural state, the elastic airbag 242 is not squeezed, and the counterweight block 2432 and the spring 2433 are both in an initial stable state.

[0071] Step 3: After the motor 4 is started, the transmission gear at its output end meshes with the outer teeth of the double gear ring 32, and when the double gear ring 32 is driven to rotate, since the number of outer teeth of the double gear ring 32 is greater than the number of inner teeth, different transmission effects will be produced when transmitting power. The outer teeth of the double gear ring 32 directly transmit power to the turntable 31 connected thereto, and the turntable 31 drives the filter assembly 23 to rotate through the linkage rod 236, so that the filter assembly 23 obtains a higher speed. As the motor 4 continues to run, the speed of the motor 4 continues to increase, thereby causing the filter assembly 23 to rotate faster. The speed eventually reaches the maximum speed of the motor 4. While the double gear ring 32 drives the turntable 31 to rotate, the inner ring teeth of the double gear ring 32 mesh with the power gear 312 through the indirect gear 313. The power gear 312 is fixed on the rotating shaft 311, thereby driving the rotating shaft 311 to rotate, and then rotating the hollow rod 33. However, since the number of teeth on the inner ring of the double gear ring 32 is less than the number of teeth on the outer ring, the speed transmitted to the rotating shaft 311 through the indirect gear 313 is lower than the speed of the turntable 31, that is, the speed transmitted to the hollow rod 33 is lower than the speed of the filter assembly 23.

[0072] Among them, when the motor 4 reaches the maximum speed, the inertial telescopic assembly 36 located in the hollow rod 33 is triggered and started. The counterweight ball 363 in the inertial telescopic assembly 36 accumulates a large inertia due to the high-speed rotation, and its inertial force overcomes the resistance of the yielding telescopic rod 361 (for example: assuming that the mass of the counterweight ball 363 is 0.5 kg and the rotation radius is 0.2 m, when the centrifuge reaches the maximum speed of 1250 rpm, the speed is converted into angular velocity, 1250 rpm = 1250 ÷ 60 × 2π ≈ 130.9 rad / s, according to the centripetal force formula F = mω 2 r, inertial force generated by the weight ball 363 F = 0.5 × 130.9 2 ×0.2≈1713.5N, at this time, the inertial force can be regarded as the yield force that overcomes the resistance of the yield telescopic rod 361 and causes it to extend), causing the yield telescopic rod 361 to gradually extend, driving the sliding frame 362 to slide from the inside to the outside along the hollow rod 33, and the sliding frame 362 extends to the maximum extension length of the yield telescopic rod 361.

[0073] When the slide frame 362 reaches the maximum extension length of the yield telescopic rod 361, as the filter assembly 23 continues to rotate at high speed and the hollow rod 33 rotates lower than the filter assembly 23, the material continues to move under the action of centrifugal force and collides with the crushing knife 376 of the elastic crushing assembly 37. When the material hits the crushing knife 376, due to the certain impact force of the material, it will push the slider 375 to slide on the slide 374, and the positioning plates 372 symmetrically arranged on both sides of the fixed seat 371 provide guidance and constraints for the sliding of the slider 375, so that during the sliding process of the slider 375, the flexible spring 373 will be compressed to play a buffering role. This buffering mechanism avoids the subsequent crushing knife 376 from being damaged due to excessive impact force, ensuring that the crushing knife 376 can work continuously and stably.

[0074] When the crushing knife 376 comes into contact with the material, it crushes the agglomerated material and breaks the larger material agglomerates into smaller particles, making the solid particles more evenly dispersed, which is conducive to the subsequent liquid passing through the filter more smoothly and improving the efficiency and quality of solid-liquid separation.

[0075] In which, while the material collides with the crushing knife 376 in the elastic crushing component 37, since the stirring frame 384 of the stirring component 38 is composed of multiple inclined plates with different inclinations, when the hollow rod 33 drives the sliding frame 362 to rotate, the stirring frame 384 moves in the material together with the sliding frame 362. Due to the special design of the inclined plates, the stirring frame 384 also collides with the material. During the frequent collisions with the material, the stirring frame 384 will be subjected to the reaction force of the material, thereby providing power for the rotation of the rotating rod 381. After the rotating rod 381 obtains the rotational power, it drives the hollow spiral cover 382 and the resistance fan plate 383 of the rod body to rotate together. During the rotation, the hollow spiral cover 382 can change the movement trajectory of the material to prevent the material from concentrating in a certain area. At the same time, the resistance fan plate 383 will increase the friction and collision between the materials when rotating, so that the solid particles and liquid in the material are more fully mixed and dispersed. In this way, the aggregation of the material is reduced, the effect of solid-liquid separation is improved, and it is ensured that the liquid can pass through the conical filter 235 more fully, reducing the obstruction of solid particles to liquid separation.

[0076] Special explanation is required: when the yield telescopic rod 361 is extended, it drives the slide frame 362 to slide from the inside to the outside along the hollow rod 33 to the maximum extension length. The slide frame 362 basically slides out of the hollow rod 33 completely, but in order to prevent the material from entering the hollow rod 33 and affecting the operation of the equipment, a small part of its bottom does not slide out. This part of the bottom that has not slid out serves as a blocking structure and fits with the inner wall of the hollow rod 33. During the operation of the equipment, even if the material continuously impacts the slide frame 362, it can still stably block the material from entering the internal space of the hollow rod 33, thereby ensuring the cleanliness of the interior of the hollow rod 33, ensuring the normal operation of components such as the inertial telescopic assembly 36, the elastic crushing assembly 37 and the stirring assembly 38, and maintaining the overall operation stability and solid-liquid separation efficiency of the equipment.

[0077] Step 4: When the spiral piece 34 located on the shaft of the hollow rod 33 rotates, the spiral piece 34 cooperates with the rebound cleaning component 24 to push the solid material to the discharge barrel 39, and finally discharges the equipment through the discharge square tube 391, completing the entire solid-liquid separation process.

[0078] When the spiral piece 34 rotates, it cooperates with the rebound cleaning component 24 to gradually move the material toward the discharge barrel 39. This is because: when the hollow rod 33 rotates, the spiral piece 34 rotates accordingly. Its spiral structure causes the material to be subjected to a component force along the spiral line during the rotation. This component force pushes the material to move toward the discharge barrel 39. When the spiral piece 34 moves the material, the material contacts the rebound cleaning component 24 under the action of centrifugal force, and the elastic component will undergo elastic deformation. According to Hooke's law F=-kx (where F is the elastic force, k is the stiffness coefficient, and x is the deformation variable), the elastic component will produce elastic deformation when it is impacted by the material. The elastic force is generated in the opposite direction of the impact force, which acts as a buffer, slowing down the movement speed of the material, preventing the material from being excessively dispersed or splashed due to high-speed impact, and allowing the material to be more concentrated within the range of action of the spiral piece 34, making it easier for the spiral piece 34 to capture the material. In addition, when the impact force of the material disappears, the elastic component returns to its original state, and slight vibration and displacement will be generated during the recovery process. This vibration and displacement helps to loosen the material that is tightly fitted due to centrifugal force, reduce the friction between the materials, make it easier for the spiral piece 34 to push the material, and further enhance the ability of the spiral piece 34 to push the material to move toward the discharge barrel 39.

[0079] It should be noted that when the material moves in the spiral blade 34, it will not be affected by the sliding inertial telescopic component 36 and the internal elastic crushing component 37 and stirring component 38, because: although the inertial telescopic component 36 slides out of the hollow rod 33, the bottom part is still inside the rod, which limits its range of movement, so that the elastic crushing component 37 and stirring component 38 will not directly interfere with the spiral blade 34 pushing the material. In terms of movement, the spiral blade 34 rotates stably to push the material axially, and the sliding inertial telescopic component 36 drives the internal components to mainly perform radial or local material processing actions, which is different from the axial movement direction of the spiral blade 34, and the spiral blade 34 continues to push the material. The inertial telescopic component 36 and its internal components are only started after the filter component 23 reaches the maximum speed, and its function is to improve the material separation effect, not to hinder the movement of the material on the spiral blade 34, so the material can stably move to the discharge barrel 39 under the push of the spiral blade 34.
