Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment equipment, in particular to compact and efficient integrated sewage treatment equipment. Background Art

[0002] As a highly efficient solid-liquid separation method, flotation separation technology is widely used in wastewater treatment, particularly for treating oily wastewater, algae-laden water, and industrial wastewater containing light suspended solids. Its core principle is to introduce a large number of tiny bubbles into the water, causing them to adhere and bind to suspended particles (scum) in the wastewater, forming a "bubble-particle" complex with a density lower than that of water. Buoyancy then causes the bubbles to rise to the surface of the liquid, forming a scum layer. This scum is then removed by a scraping device, achieving water purification.

[0003] Flotation separation technology is a key means of efficiently removing scum in wastewater treatment. Its core principle is to utilize microbubbles to bind impurities and cause them to float to the surface, forming a scum layer that is then removed by a scraping device. Traditional scraping systems typically consist of a drive unit, a transmission chain, and an integral rigid scraper mounted on top. The scraper moves along a rectangular trajectory, pushing scum from the liquid surface in the flotation separation zone to the sloped diversion weir at the end, where it is ultimately directed into a scum trough for discharge.

[0004] However, this fixed integrated scraper has significant defects in practical applications:

[0005] First, when the scraper contacts the sloped weir, due to the limitations of its rigid structure and rectangular running track, it can usually only form a single-line contact or a very small range of contact. This makes it impossible for the scraper to effectively fit the inclined weir surface, and a gap is generated between the scraper and the weir. As a result, a large amount of scum cannot be effectively pushed to the scum collection area and remains or falls back, seriously affecting the scum removal effect and the water quality of the effluent.

[0006] Secondly, the scraper angle is fixed and cannot be adaptively adjusted according to the angle of the slope weir plate and the chain operation status (or scum) characteristics. The non-ideal contact state not only aggravates the contact stress at local points, but also causes rapid wear of the contact parts between the scraper and the weir plate, shortening the life of the equipment.

[0007] To this end, the present invention proposes a compact and efficient integrated sewage treatment equipment to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] Secondly, the term "one embodiment" or "embodiment" herein refers to specific features, components, or characteristics that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0042] Example 1:

[0043] Reference Figure 1-10 FIG. 1 is a first embodiment of the present invention, which provides a compact and efficient integrated sewage treatment device, comprising:

[0044] The processing tank body 100 is provided with a diversion and separation weir plate 101 along the width direction of the processing tank body 100, that is, at the tail end of the processing tank body 100. The diversion and separation weir plate 101 includes an integrated diversion trough plate 1011 and a slope plate 1012. The water flows through the slope plate 1012 and the diversion trough plate 1011 in sequence. The diversion trough plate 1011 and the inner wall of the processing tank body 100 constitute a scum collection area. The scum collection area passes through the processing tank body 100 to form a scum outlet 102.

[0045] In one embodiment, the slag outlet 102 is externally connected to a slag discharge pipe and a suction pump, so that the suction force generated by the suction pump sucks the slag through the slag discharge pipe.

[0046] like Figure 2 and Figure 3 As shown, the end of the treatment tank body 100 away from the diversion and separation weir plate 101, that is, the head of the treatment tank body 100, is provided with a water inlet mixing zone baffle 103 and a dissolved air separation zone baffle 104. The water inlet mixing zone baffle 103 and the dissolved air separation zone baffle 104 are laid along the water flow direction in the treatment tank body 100. The water inlet mixing zone baffle 103, the dissolved air separation zone baffle 104 and the diversion and separation weir plate 101 divide the chamber of the treatment tank body 100 into a water inlet mixing zone, a dissolved air release zone, a flotation separation zone and a water outlet zone in sequence along the water flow direction; wherein, the flotation separation zone and the water outlet zone are connected, and the slag collection zone is arranged above the water outlet zone.

[0047] In one embodiment, a dissolved air water distribution pipe 1041 for connecting the dissolved air release zone and the flotation separation zone is respectively installed on the water inlet mixing zone partition 103 and the dissolved air release zone, and on the dissolved air separation zone partition 104. A pressure dissolved air system is provided on the outer wall of the processing tank body 100. The pressure dissolved air system produces dissolved air water and releases the dissolved air water to the dissolved air release zone to form dense bubbles that combine with floating dust to form scum.

[0048] In one embodiment, if Figure 2 and Figure 7 As shown, the pressure dissolved air system includes a dissolved air pump 1081, an air compressor, a pressure regulating valve, an air dissolving tank 1082, a transverse water distribution pipe 1083, and an aeration head. The dissolved air pump 1081 draws water from the water outlet of the treatment tank 100 and delivers it to the dissolved air tank 1082 together with the compressed air injected by the air compressor. The pressure regulating valve is located at the outlet of the dissolved air tank 1082. The pressure regulating valve precisely controls the output pressure of the dissolved air water at the outlet of the dissolved air tank 1082, ensuring that the dissolved air water enters the dissolved air release zone through the transverse water distribution pipe 1083 at a stable pressure. At the same time, the aeration head installed at the output end of the transverse water distribution pipe 1083 forms dense bubbles for exposure. When the dissolved air water enters the dissolved air release zone, due to the sudden drop in ambient pressure, the supersaturated dissolved air water quickly precipitates from the aeration head in the form of tiny bubbles. The tiny bubbles efficiently combine with the scum particles in the water to form scum, which floats to the water surface in the flotation separation zone along with the water flow.

[0049] like Figure 2 and Figure 3 As shown, a cover plate 1091 is provided above the water inlet mixing zone, which is cooperatively supported by the treated tank body 100 and the water inlet mixing zone partition 103. The cover plate 1091 is assembled on the treatment tank body 100 and the water inlet mixing zone partition 103 by bolts. The cover plate 1091 is equipped with a stirring assembly and a feeding pipe 1095. The feeding pipe 1095 is used to feed chemical agents such as bactericides and coagulants into the sewage, and the stirring assembly is used to mix the sewage and the chemical agents.

[0050] In one embodiment, the stirring assembly includes a rotating motor 1092 mounted on a cover plate 1091, a rotating roller 1093 connected to the output end of the rotating motor 1092, and a plurality of stirring blades 1094 installed at equal intervals on the rotating roller 1093. The rotating motor 1092 drives the stirring blades 1094 to rotate through the rotating roller 1093 to evenly stir the sewage and chemical agents such as disinfectants and coagulants.

[0051] like Figure 2 and Figure 5As shown, the outer wall of the treatment tank body 100 is also equipped with a pretreatment sub-tank 105, and a water inlet pipe 106 is arranged on the outer wall of the pretreatment sub-tank 105. The water inlet pipe 106 is also equipped with a water inlet pump for controlling the water inlet speed, and a pretreatment module arranged in the inner cavity of the pretreatment sub-tank 105 for preliminary screening of sewage.

[0052] Exemplarily, a pretreatment module is integrated in the pretreatment sub-tank 105, and the pretreatment modules are stacked from top to bottom by grating plates 107 with gradually wider grating gaps. After the sewage is introduced into the pretreatment sub-tank 105 through the water inlet pipe 106 and the water inlet pump, large debris is first intercepted by the grating plates 107 with slightly wider grating gaps, and then fine suspended matter is intercepted and captured by the grating plates 107 with slightly finer grating gaps, so as to intercept and filter the sewage step by step to complete the preliminary screening of the sewage.

[0053] A chain drive system is arranged in the processing tank body 100, and the chain drive system includes a tensioning device, a power drive unit for driving the tensioning device to circulate, and a composite scraper assembly hinged on the tensioning device; wherein the composite scraper assembly includes a main scraper 231 rotatably connected to the tensioning device, an auxiliary scraper 232 hinged on the main scraper 231, and an adaptive adjustment assembly, the auxiliary scraper 232 contacts the ramp plate 1012 and is tilted to squeeze the adaptive adjustment assembly, the adaptive adjustment assembly is deformed under pressure, and then adaptively adjusts the angle between the main scraper 231 and the auxiliary scraper 232, the main scraper 231 that is continuously under pressure drives the auxiliary scraper 232 to move to squeeze the adaptive adjustment assembly and then adjust the angle between the auxiliary scraper 232 and the tensioning device.

[0054] In one embodiment, the auxiliary scraper 232 is hinged to an end of the main scraper 231 away from the tensioning device.

[0055] Reference Figure 1 、 Figure 2 as well as Figure 7 As shown, the tensioning device includes two sets of tensioning modules, a transmission chain 212 for linking the two sets of tensioning modules, and a bearing seat mounting base 211 that supports and limits the tensioning modules. The bearing seat mounting base 211 is assembled on the top surface of the processing tank body 100;

[0056] Each tensioning module includes a drive shaft 213 engaged in the bearing seat mounting base 211, two sprockets 214 assembled on the drive shaft 213 and symmetrically arranged along the length of the processing tank body 100, and transmission gears 215 assembled on both ends of the drive shaft 213.

[0057] Specifically, a slewing support bearing is installed in the bearing seat mounting base 211, and the bearing seat mounting base 211 is movably connected to the drive shaft 213 through the slewing support bearing. The transmission chain 212 is laid along the length direction of the processing tank body 100 and engages with the transmission sprocket 214. The power drive unit drives a group of tensioning modules to rotate, and the two groups of tensioning modules are rotated synchronously through the transmission chain 212, so that the two transmission chains 212 engaged on the two tensioning modules circulate, and then the composite scraping assembly assembled on the transmission chain 212 synchronizes the movement of the transmission chain 212 to scrape the residue.

[0058] Reference Figure 7 As shown, the power drive unit includes a motor base plate 221 assembled on the top surface of the processing tank body 100, a driving motor 222 installed on the motor base plate 221, an active transmission wheel 223 assembled on the output end of the driving motor 222, a driven transmission wheel 224 assembled on the driving shaft 213, and a main transmission chain 225 for linking the active transmission wheel 223 and the driven transmission wheel 224 to rotate synchronously.

[0059] like Figure 7 and Figure 8 As shown, the transmission chain 212 includes a plurality of mutually hinged chain plates 2121 and a pin pair 2122 for hingedly connecting adjacent chain plates 2121. Two adjacent groups of chain plates 2121 are rotatably connected by the pin pair 2122.

[0060] The two corners of the main scraper 231 near the chain plate 2121 are concave to form an avoidance groove, which passes through and engages the reference shaft 236 of the main scraper 231. The reference shaft 236 includes a pin shaft pair 2122 that is symmetrically arranged along the width of the processing tank body 100 and connected to the corresponding position. The purpose of the avoidance groove is to allow the main scraper 231 to have a larger rotation space during the rotation process.

[0061] Exemplarily, the pin pair 2122 includes a positioning pin that passes through the hinge of adjacent chain plates 2121 and wear-resistant bushings disposed at both ends of the positioning pin.

[0062] like Figure 7 and Figure 8 As shown, the adaptive adjustment component includes a connecting truss 233 assembled on the main scraper 231, a V-shaped plate 234 that is rotatably and limitably connected to both ends of the connecting truss 233, and two groups of telescopic springs 235 connected to the forked side of the V-shaped plate 234, one group of telescopic springs 235 is connected to the main scraper 231, and the other group of telescopic springs 235 is connected to the auxiliary scraper 232.

[0063] In one embodiment, the truss includes a main shaft, a plurality of connecting diagonal rods arranged between two V-shaped plates 234, and a plurality of limit plates assembled on the main shaft; wherein the connecting diagonal rods are laid on the main shaft at equal intervals and are fixed to the main shaft, and the end of the connecting diagonal rod facing away from the main shaft is connected to the main scraper 231, and a plurality of limit plates are arranged on both sides of the V-shaped plate 234 for limiting the position of the V-shaped plate 234 on the main shaft.

[0064] During operation, the sewage is pumped into the pretreatment sub-tank 105 by the water inlet pump through the water inlet pipe 106. The grid plates 107 with different grid gap widths in the inner cavity of the pretreatment sub-tank 105 realize step-by-step filtration to intercept impurities of different particle sizes such as plastic bottles, branches, fibers, and debris. The preliminarily filtered sewage enters the water inlet mixing area of ​​the treatment tank body 100.

[0065] The feeding pipe 1095 above the water inlet mixing zone simultaneously adds chemical agents such as fungicides, coagulants, and flocculants. The rotating motor 1092 drives the rotating roller 1093 to drive the fan blades to stir at high speed, so that the agents and sewage are fully mixed. The fungicide kills pathogenic microorganisms in the water. The coagulant and flocculant aid destroy the stability of the colloidal particles through neutralization, and then condense to form flocs with larger particle size, creating conditions for subsequent flotation separation.

[0066] The active drive wheel 223 in the power drive unit meshes with the driven drive wheel 224 on the drive shaft 213 via the main transmission chain 225, forming a primary transmission. When the drive motor 222 is running, torque is transmitted to the drive shaft 213 via the main transmission chain 225, driving the drive shafts 213 of the tensioning modules to rotate synchronously. Two sprockets 214 are symmetrically mounted on the drive shaft 213 of each tensioning module set, meshing with the transmission chain 212 laid along the length of the processing tank body 100, forming a secondary transmission. At the same time, the sprockets 214 at both ends of the drive shaft 213 are linked to the other tensioning module set via the transmission chain 212, ensuring that the two tensioning module sets rotate synchronously within the limit of the bearing seat mounting base 211, thereby achieving the circular motion of the tensioning device.

[0067] When the transmission chain 212 is running, the composite scraper assembly moves synchronously with the transmission chain 212. When the auxiliary scraper 232 contacts the ramp plate 1012 of the diversion and separation weir plate 101, the inclined surface of the ramp plate 1012 gives the scraper a lateral thrust toward the water inlet mixing zone partition 103, forcing the auxiliary scraper 232 to flip and rotate around the hinge point between the main scraper 231 and the auxiliary scraper 232, and the scraper tip of the auxiliary scraper 232 scrapes the inclined surface of the ramp plate 1012.

[0068] At this point, when the main scraper 231 and the auxiliary scraper 232 encounter resistance, the V-shaped plate 234, under the action of the thrust, flips around the main shaft. The tip of the V-shaped plate 234 contacts the tensioned transmission chain 212, which in turn provides support to the V-shaped plate 234. The spring connecting the main scraper 231 is compressed and contracts, slightly changing the angle between the main scraper 231 and the transmission chain 212. Secondly, the auxiliary scraper 232 directly contacts the inclined surface of the ramp plate 1012. The pressure from the ramp plate 1012 causes the auxiliary scraper 232 to rotate about the hinge point, which in turn compresses the telescopic spring 235 on the bifurcated side. As the telescopic spring 235 is compressed and contracts, the angular deflection between the auxiliary scraper 232 and the main scraper 231 decreases, forming a scraping curved surface that fits tightly against the ramp plate 1012. As the transmission chain 212 continues to move, the scraper continuously pushes the scum layer on the water surface of the flotation separation area along the ramp plate 1012 into the scum collection area, where it is sucked out from the scum outlet 102, completing the scum collection.

[0069] Compared with the fixed integrated scraper, the scraper runs along the rectangular track of the transmission chain 212 and only contacts the ramp plate 1012 with the tip of the single line. The composite scraper assembly can form a continuous contact surface when contacting the ramp plate 1012 through the hinge assembly of the main scraper 231 and the auxiliary scraper 232: when the transmission chain 212 drives the composite scraper assembly to move, the auxiliary scraper 232 rotates around the hinge point under the thrust of the ramp plate 1012, and cooperates with the adaptive adjustment group. The buffering linkage of the telescopic spring 235 and the V-shaped plate 234 in the component expands the contact surface between the auxiliary scraper 232 and the ramp plate 1012 from a single line to a continuous surface contact, which not only avoids the problem of scum missing caused by the single-line contact of the fixed scraper, but also completely pushes the scum on the liquid surface of the flotation separation area to the scum collection area through the continuous contact surface of the auxiliary scraper 232 and the ramp plate 1012. Compared with the single-point scraping mode of the fixed scraper, the scraping efficiency and the thoroughness of scum collection are significantly improved.

[0070] Compared with the fixed integral scraper, the composite scraper assembly can automatically adjust the scraping posture according to the inclination angle of the diversion separation weir plate 101 and the ramp plate 1012 through the hinged design of the main scraper 231 and the auxiliary scraper 232 and the adaptive adjustment component. The fixed integral scraper runs along the rectangular trajectory of the transmission chain 212. Due to the flexible avoidance of the transmission chain 212, it can only form a small section of continuous surface contact with the ramp plate 1012, making it difficult to ensure that there is no missed scraping during the scraping process. When the composite scraper assembly contacts the ramp plate 1012, the linkage mechanism of the telescopic spring 235 and the V-shaped plate 234 enables the scraper group to continuously fit the ramp plate 1012, forming a continuous linear surface contact, realizing the transition from single-line contact to continuous surface contact, which not only greatly improves the scum collection efficiency, but also reduces local wear by dispersing the force points, thereby extending the service life of the scraper. At the same time, the adaptive adjustment component can buffer the scraping resistance and reduce the load impact of the chain drive system. Especially when dealing with high-concentration scum, it can ensure continuous and efficient scraping by dynamically adjusting the contact angle, ensure the cleanliness of the liquid surface in the flotation separation area, and improve the operating stability and reliability of the overall sewage treatment equipment.

[0072] Reference Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 as well as Figure 9 FIG2 is a second embodiment of the present invention, which is based on the previous embodiment, except that a slag guide assembly 310 is provided in the slag collection area, and the slag guide assembly 310 includes an elastic slag pushing chamber and a chamber driving mechanism 320 provided in the elastic slag pushing chamber. A primary linkage assembly 331 is provided between the chamber driving mechanism 320 and the tensioning device. The power drive unit drives the tensioning device to move back and forth, thereby driving the primary linkage assembly 331 to move. The moving primary linkage assembly 331 drives the chamber driving mechanism 320 to move back and forth, so that the elastic slag pushing chamber is expanded and closed, and the slag is continuously pushed back and forth toward the slag outlet 102.

[0073] In one embodiment, the guide trough plate 1011 and the inner wall of the processing tank body 100 form a special-shaped chamber with at least two long and short sides, and its elastic slag pushing chamber is engaged in the slag collection area and only moves linearly along the width direction of the processing tank body 100.

[0074] In one embodiment, the elastic slag pushing chamber is disposed at one end of the processing tank body 100 away from the slag outlet 102 , and the processing tank body 100 has a square opening facing the slag outlet 102 , and the first-stage linkage component 331 engages with the chamber driving mechanism 320 through the square opening.

[0075] like Figure 9As shown, the elastic slag pushing chamber includes a first frame box 311 arranged in the slag collection area, a second frame plate 312 arranged on the side of the first frame box 311 away from the slag outlet 102 and parallel to the first frame box 311, and an elastic connecting membrane 313 for connecting the first frame box 311 and the second frame plate 312. The second frame plate 312 is connected to the inner wall of the processing tank body 100. The first frame box 311 moves along the axis direction of the slag collection area under the action of external force and the guidance of the anisotropic chamber.

[0076] like Figure 6 、 Figure 7 、 Figure 9 as well as Figure 10 As shown, the chamber driving mechanism 320 includes a telescopic component 321, a rebound component 322, and a passive driving component 323 connected to the telescopic component 321, which are arranged in the elastic slag pushing chamber. The first-level linkage component 331 is arranged between the driving component and the tensioning device. The power driving unit drives the tensioning device to cyclically move to drive the first-level linkage component 331 to move. The moving first-level linkage component 331 drives the passive driving component 323 to rotate to drive the telescopic component 321 to extend and retract, so as to cooperate with the rebound component 322 to drive the first frame box 311 to reciprocate relative to the second frame plate 312.

[0077] Among them, such as Figure 10 As shown, the telescopic assembly 321 includes a telescopic frame and a transmission bevel gear 3213 assembled on the telescopic frame. The transmission bevel gear 3213 is engaged with the helical gear 32343. The telescopic frame is driven by the transmission bevel gear 3213 to rotate to extend or retract itself.

[0078] Reference Figure 10 As shown, the telescopic skeleton includes a first link assembly 3211 and a second link assembly 3212. The number of the second link assemblies 3212 is multiple and arranged linearly. Adjacent second link assemblies 3212 are hinged to each other. The number of the first link assemblies 3211 is two. The two groups of first link assemblies 3211 are arranged at both ends of the multiple groups of linearly arranged second link assemblies 3212. A group of link assemblies facing away from the second frame plate 312 is connected to the first frame box 311. The first link assembly 3211 is assembled on the inner wall of the second frame plate 312. The second frame plate 312 is driven to move toward or away from the first frame box 311 through the telescopic skeleton's own telescopic movement.

[0079] Exemplarily, the transmission bevel gear 3213 is assembled on a set of first connecting rod assemblies 3211 facing away from the second frame plate 312, and the first connecting rod assembly 3211 includes two vertical round rods 32111 and two horizontal round rods 32112 forming a cross, and a central base plate 32113 is arranged at the connection between the vertical round rods 32111 and the horizontal round rods 32112. Both ends of the vertical round rods 32111 and the horizontal round rods 32112 are assembled on hinged short plates 32114.

[0080] In a set of first connecting rod assemblies 3211 facing away from the second frame plate 312, a center base plate 32113 is provided at the center of the cross formed by two vertical round rods 32111 and two horizontal round rods 32112. The vertical round rods 32111 extend from the upper and lower surfaces of the center base plate 32113 and are rotatably connected to the center base plate 32113. The vertical round rods 32111 are inserted into the first frame box 311 to fix the position of the first connecting rod assembly 32111. The horizontal round rods 32112 are connected from the center base plate 32113 to the center base plate 32113. 2113 extends to the left and right sides and forms a rotational connection with the central base plate 32113; the hinged short plates 32114 located at the ends of the horizontal round rod 32112 and the vertical round rod 32111 are both rotatably connected to the horizontal round rod 32112 and the vertical round rod 32111, and the hinge point of the horizontal round rod 32112 and the vertical round rod 32111 at the hinged short plate 32114 is located at one end of the hinged short plate 32114, and the other end of the hinged short plate 32114 is used to hinge the second connecting rod assembly 3212.

[0081] In a group of first connecting rod assemblies 3211 close to the second frame plate 312 , the central base plate 32113 is fixed to the surface wall of the second frame plate 312 .

[0082] The second connecting rod assembly 3212 is similar to the first connecting rod assembly 3211, except that the length of the hinged short plate 32114 in the second connecting rod assembly 3212 is greater than the length of the hinged short plate 32114 in the first connecting rod assembly 3211, and the hinge points of the hinged short plate 32114 in the second connecting rod assembly 3212 and the vertical round rod 32111 and the horizontal round rod 32112 are located at the center of the hinged short rod, and the two ends of the hinged short plate 32114 in the second connecting rod assembly 3212 are respectively hinged to the adjacent second connecting rod assembly 3212 or the first connecting rod assembly 32111.

[0083] Reference Figure 9 and Figure 10 As shown, the rebound assembly 322 includes a rebound spring 3221 and a base plate 3222 assembled on the rebound spring 3221 . The end of the rebound spring 3221 facing away from the base plate 3222 is assembled on the surface wall of the first frame box 311 , and the base plate 3222 is installed on the inner wall of the second frame plate 312 .

[0084] like Figure 6、 Figure 7 、 Figure 9 as well as Figure 10 As shown, the passive drive assembly 323 includes a rotating shaft 3231 inserted into the surface wall of the processing tank body 100, a flywheel 3232 and a bevel gear 3233 coaxially assembled on the rotating shaft 3231, and a spiral assembly assembled on the outer wall of the processing tank body 100, and the spiral assembly and the bevel gear 3233 are meshed and driven.

[0085] A plurality of spiral grooves are formed at equal intervals on the surface of the bevel gear 3233 , so that the spiral teeth on the surface of the bevel gear 3233 are distributed in sections, and the partial area where the spiral teeth are distributed forms a continuous spiral tooth row.

[0086] For example, Figure 6 As shown, the spiral assembly includes a base 32341 assembled on the surface wall of the processing tank body 100, a spiral shaft 32342 engaged and rotated inside the base 32341, and a spiral gear 32343 engaged with the bevel gear 3233.

[0087] like Figure 7 and Figure 9 As shown, the primary linkage assembly 331 includes a coaxial gear 3311 assembled on the end of the drive shaft 213 and a traction chain 3312 engaged with the coaxial gear 3311. The coaxial gear 3311 is linked to the flywheel 3232 for rotation through the traction chain 3312.

[0088] During operation, when the drive motor 222 in the power drive unit is running, torque is transmitted to the drive shaft 213 through the main transmission chain 225, driving the drive shaft 213 to rotate synchronously. At this time, the coaxial gear 3311 at the end of the drive shaft 213 rotates with the drive shaft 213, forming a transmission connection with the flywheel 3232 of the passive drive assembly 323 through the traction chain 3312, so that the flywheel 3232 drives the rotating shaft 3231 and the coaxial bevel gear 3233 to rotate synchronously. The bevel gear 3233 meshes with the helical gear 32343 in the helical assembly. Because the helical teeth on the surface of the helical gear 32343 are distributed in sections, when the bevel gear 3233 rotates, its spiral teeth row periodically drives the transmission bevel gear 3213 to rotate.

[0089] The transmission bevel gear 3213 is assembled on the horizontal round rod 32112 of the telescopic frame. As the transmission bevel gear 3213 rotates, the hinged short plate 32114 in the first connecting rod assembly 3211 away from the second frame plate 312 moves from the inclined angle to the axial direction along the telescopic frame. The hinged short plate 32114 of the first connecting rod assembly 3211 pushes the adjacent second connecting rod assembly 3212 to move backward, thereby driving the angles of other hinged short plates 32114 of the first connecting rod assembly 3211 to change synchronously.

[0090] Since the hinged short plates 32114 at both ends of the horizontal round rod 32112 in the first connecting rod assembly 3211 are hinged to the hinged short plates 32114 in the second connecting rod assembly 3212, the hinged short plates 32114 in the second connecting rod assembly 3212 are driven to be corrected to be along the axial direction of the telescopic frame, and the second connecting rod assembly 3212 itself expands. Similarly, the multiple groups of second connecting rod assemblies 3212 at the rear end and the first connecting rod assembly 3211 at the tail end produce corresponding linkage actions, so that the telescopic frame is expanded through the hinged linkage of the first connecting rod assembly 3211 and the second connecting rod assembly 3212, and the contraction action of the telescopic frame is opposite to the above process.

[0091] When the telescopic frame is extended, it pushes the first frame box 311 to move away from the second frame plate 312. At this time, the elastic connecting membrane 313 connecting the first frame box 311 and the second frame plate 312 is stretched, and the elastic slag pushing chamber is expanded. The rapidly moving first frame box 311 pushes the slag collected in the slag collection area to move quickly toward the slag outlet 102, and is sucked out by the suction of the slag outlet 102, thereby preventing the slag far away from the slag outlet 102 from accumulating due to insufficient suction.

[0092] When the transmission helical gear 3213 rotates to the non-helical tooth row area, the telescopic frame loses its driving force. At this time, the rebound spring 3221 in the rebound assembly 322, which is mounted on the surface of the first frame box 311, applies a reset tension to the first frame box 311 through the base plate 3222, driving the first frame box 311 toward the second frame plate 312, causing the telescopic frame to shorten and the elastic slag pushing chamber to close. The telescopic assembly 321 and the rebound assembly 322 work together periodically to drive the first frame box 311 to reciprocate along the width of the processing tank body 100 within the slag collection area, away from or toward the second frame plate 312, achieving the expansion and contraction of the elastic slag pushing chamber, thereby continuously pushing the slag toward the slag outlet 102 and preventing slag accumulation.

[0093] By adding an elastic slag pushing chamber and a chamber driving mechanism 320 in the slag collection area, using the reciprocating motion of the tensioning device as the power source, and driving the telescopic component 321 and the rebound component 322 to work together through the first-level linkage component 331, the elastic slag pushing chamber is periodically expanded and closed in the slag collection area, forming a continuous pushing force on the slag, effectively solving the problem of slag accumulation at the edge of the traditional static collection area due to insufficient suction, significantly improving the slag discharge efficiency, reducing energy consumption, and improving the overall reliability of the equipment, thereby extending the maintenance cycle.

[0094] Example 3:

[0095] Reference Figure 3 and Figure 5FIG. 3 is a third embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that it further includes a scraper self-cleaning system 410 mounted on the upper portion of the processing tank 100. The power drive unit drives the composite scraper assembly to rotate until it abuts against the scraper self-cleaning system 410, and the auxiliary scraper 232 contacts the scraper self-cleaning system 410 and is tilted by force.

[0096] A secondary linkage assembly 420 is arranged between the scraper self-cleaning system 410 and the tensioning device. The power drive unit drives the tensioning device to reciprocate to drive the secondary linkage assembly 420 to move. The moving secondary linkage assembly 420 drives the scraper self-cleaning system 410 to rotate to scrape the surface of the auxiliary scraper 232.

[0097] In one embodiment, the scraper self-cleaning system 410 includes two vertical columns 411 mounted on the surface wall of the processing tank body 100, a coaxially arranged cam shaft 412, a cleaning roller 413 and a cleaning sleeve roller 414; wherein, the cleaning sleeve roller 414 is horizontally supported and fixed by the two columns 411, the cam shaft 412 passes through the cleaning sleeve roller 414 and is supported by the column 411 and rotates on the surface of the column 411, and the cleaning roller 413 is mounted on the part of the rod body of the cam shaft 412 set inside the cleaning sleeve roller 414.

[0098] In one embodiment, the bottom end section of the cleaning sleeve roller 414 is bent and abuts against the surface of the cleaning roller 413. The cleaning roller 413 is driven to rotate by external force so as to be abutted and scraped by the cleaning sleeve roller 414 to achieve self-cleaning. The auxiliary scraper 232 moves to the cleaning roller 413, and the rotating cleaning roller 413 scrapes the auxiliary scraper 232 for cleaning.

[0099] Exemplarily, the cleaning roller 413 adopts a three-layer composite structure design. From the inside to the outside, the cleaning roller 413 consists of a core layer, an adsorption layer and a wear-resistant layer. The core layer adopts a high-elasticity polyurethane foam material to provide radial compression rebound performance to ensure a close fit with the cleaning sleeve roller 414. At the same time, a spiral spring steel skeleton is embedded inside to enhance the anti-twisting ability; the adsorption layer adopts modified polyester fiber felt, and its surface is treated with oleophilic and hydrophobic modification to increase the adsorption efficiency of oil and grease scum. At the same time, the surface has dense micropores to improve the stain retention ability; the wear-resistant layer adopts a silicone coating layer.

[0100] In one embodiment, the secondary linkage assembly 420 includes a conveying chain 421 sleeved on the transmission gear 215, and a transmission cam 422 sleeved on the cam shaft 412, and the conveying chain 421, the transmission cam 422 and the transmission gear 215 are all arranged in a meshing transmission.

[0101] During operation, when the drive motor 222 in the power drive unit is running, torque is transmitted to the drive shaft 213 through the main transmission chain 225, driving the drive shaft 213 of the tensioning device to rotate synchronously. The transmission gears 215 at both ends of the drive shaft 213 rotate accordingly, and the conveyor chain 421 connected to the transmission gear 215 begins to run. The conveyor chain 421 engages with the transmission cam 422 on the cam shaft 412, thereby driving the cam shaft 412 to rotate. The cleaning roller 413 mounted on the cam shaft 412 rotates along with the cam shaft 412. When the composite scraper assembly moves with the transmission chain 212 to the scraper self-cleaning system 410, the auxiliary scraper 232 contacts the cleaning roller 413 and is tilted. During the movement, the auxiliary scraper 232 is squeezed by the cleaning roller 413 and adaptively adjusts to different postures, so that the surface of the auxiliary scraper 232 is in continuous contact with the cleaning roller 413 to clean the entire surface of the auxiliary scraper 232. Its adsorption layer absorbs adhering stains on the auxiliary scraper 232. At the same time, the bottom end of the cleaning sleeve roller 414 is bent and abuts against the surface of the cleaning roller 413. When the cleaning roller 413 rotates, relative friction is generated between the cleaning sleeve roller 414 and the cleaning roller 413. The squeezing and friction of the cleaning sleeve roller 414 cause the adsorption layer of the cleaning roller 413 to be radially compressed, squeezing the adsorbed stains onto the surface of the cleaning sleeve roller 414. The stains slide along the surface of the cleaning sleeve roller 414 into the flotation separation area. Because the core layer of the cleaning roller 413 is made of highly elastic polyurethane foam material and embedded with a spiral spring steel skeleton, it can quickly rebound after being pressed against the cleaning sleeve roller 414, restoring its adsorption capacity, thereby achieving continuous cleaning of the scraper by the cleaning roller 413 and self-cleaning. During the entire process, the power drive unit drives the tensioning device to reciprocate, and the scraper self-cleaning system 410 operates synchronously through the secondary linkage assembly 420, ensuring that stains on the surface of the composite scraper assembly are removed in a timely manner.
