Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an intelligent screen residue treatment device. Background Art

[0002] With the acceleration of urbanization and the development of industrial production, the amount of sewage generated is increasing. Sewage is often mixed with various residues, such as leaves, paper scraps and plastic bags. The traditional screen residue treatment method may be inefficient, and there are problems such as incomplete residue cleaning, and some residues still remain on the treatment equipment, affecting subsequent use. In particular, flocculent residues usually have irregular shapes and soft textures, which are easily entangled on the grid plates of the grille, or accumulated in the gaps of the grid plates, affecting the effect of sewage treatment and accelerating the wear of equipment. Therefore, a more intelligent and efficient device is needed to cope with the growing workload of sewage treatment and screen residue treatment.

[0003] For example, China Patent Publication No.: CN222250069U, the utility model discloses a grille dirt remover that is easy to disassemble and assemble, and relates to the technical field of rotary grille dirt removers, including a dirt remover frame and a disassembly assembly component, the dirt remover frame is provided with a disassembly assembly component, the disassembly assembly component includes a connecting roller, a slot, a screw, a mounting plate, a threaded hole and a tooth rake, a slot is provided in the middle of the connecting roller, and screws are provided at both ends of the slot, a mounting plate is plugged into the slot, and threaded holes are provided at both ends of the mounting plate, and tooth rakes are arranged along the extension direction at the front end of the mounting plate. This application provides a grille dirt remover that is easy to disassemble and assemble. Through the setting of the disassembly assembly component, when disassembling and replacing the tooth rake of the wearing part, it is only necessary to unscrew the screws at both ends of the connecting roller and pull the mounting plate out of the slot, and then insert the replacement part into the slot again, and fix the rear end of the mounting plate to the screw through the threaded hole, so as to realize the quick disassembly and assembly of the tooth rake and shorten the downtime of the rotary grille dirt remover.

[0004] The prior art still has the following problems:

[0005] The existing technology cannot timely clean the irregularly shaped and soft flocculent residues entangled in the gaps between the grid plates, which affects the timeliness of the cleaning of the grid residue and the effect of sewage treatment. Utility Model Content

[0006] To this end, the utility model provides an intelligent screen residue processing device to overcome the problem that the prior art cannot timely clean the irregularly shaped and soft flocculent residues entangled in the gaps between the screen plates.

[0007] In order to achieve the above-mentioned purpose, the utility model provides an intelligent screen slag processing device, comprising:

[0008] The machine body comprises a support frame and traction mechanisms respectively arranged on both sides of the support frame, wherein the traction mechanisms comprise a sprocket and an annular chain meshed on the sprocket;

[0009] The annular grid plate comprises a plurality of rectangular mesh plates, and both ends of each rectangular mesh plate are connected to the annular chain so that the annular chain drives each rectangular mesh plate to rotate;

[0010] A residue cleaning mechanism, which includes a drying roller, an adsorption roller, and an oscillation roller, which are sequentially arranged on the support frame from top to bottom to dry the residue on each rectangular screen plate;

[0011] Wherein, the drying roller, the adsorption roller and the oscillation roller are respectively in contact with the rectangular screen plate rotating downward;

[0012] The residue recovery component comprises a recovery chamber arranged at one side of a downwardly rotating rectangular mesh plate for collecting residues carried by the downwardly rotating rectangular mesh plate, and a conveyor arranged at the bottom of the recovery chamber for conveying the residues.

[0013] Furthermore, the traction mechanism also includes a driving motor connected to the sprocket, and the driving motor drives the sprocket to rotate.

[0014] Furthermore, the plate surface of the rectangular mesh plate is provided with a plurality of convex hooks for hooking the residues in the sewage.

[0015] Furthermore, the drying roller, the adsorption roller and the oscillation roller are all arranged perpendicularly relative to the downward rotation direction of each rectangular mesh plate, and the arrangement heights of the drying roller, the adsorption roller and the oscillation roller are all higher than the recovery cabin.

[0016] Furthermore, the drying roller comprises an electric heating tube and a heat-conducting roller body sleeved on the electric heating tube, and the heat-conducting roller body is made of stainless steel.

[0017] Furthermore, the adsorption roller comprises a conductive roller core for adsorbing residues and an insulating layer sleeved on the conductive roller core, and the insulating layer is made of rubber.

[0018] Furthermore, the conductive roller core is connected to a power controller, and the power controller is used to supply power to the conductive roller core according to a preset time period.

[0019] Furthermore, the oscillation roller comprises an oscillation roller body and a roller shaft, and the axis of the roller shaft does not coincide with the axis of the oscillation roller body.

[0020] Furthermore, an inverted trapezoidal opening is provided on the top of the recovery chamber, so that the residues carried by the rectangular mesh plate can enter the interior of the recovery chamber through the inverted trapezoidal opening.

[0021] Furthermore, the conveyor includes a pushing motor and a screw conveying rod, and the output shaft of the pushing motor is coaxial with and fixedly connected to the screw conveying rod to drive the screw conveying rod to rotate.

[0022] Compared with the prior art, the utility model has the beneficial effect that, by providing a machine body, an annular grid, a residue cleaning mechanism and a residue recovery component, the machine body includes a support frame and a traction mechanism, the traction mechanism includes a sprocket and an annular chain meshed on the sprocket, the annular grid includes a plurality of rectangular mesh plates, the residue cleaning mechanism includes a drying roller, an adsorption roller and an oscillation roller arranged on the support frame from top to bottom, the residue recovery component includes a recovery chamber and a conveyor arranged at the bottom of the recovery chamber, and then, by drying the flocculent residue on the rectangular mesh plate and electrostatically adsorbing the dried flocculent residue, the flocculent residue entangled in the gap between the grid plates is cleaned, and by periodically energizing and deenergizing the adsorption roller, the heavy flocculent residue agglomerated on the adsorption roller falls into the recovery chamber, thereby improving the timeliness of the cleaning of the grid residue.

[0023] Furthermore, the utility model dries the residues on each rectangular mesh plate through a drying roller. It can be understood that the flocculent residues will be tightly wrapped in the gaps between the grid plates when wet. This is because the presence of water makes it have a certain viscosity. After being dried by the drying roller, the moisture in the flocculent residues is removed and its viscosity is greatly reduced, thereby making the flocculent residues dry and loose, making them easier to remove.

[0024] Furthermore, the utility model absorbs the residues through an adsorption roller that can generate static electricity, and the structure of the flocculent residues after drying becomes looser. When the adsorption roller generates an electrostatic field, the larger surface area of ​​the flocculent residues in a dry state can distribute more charges on the surface of the residues, making it easier to be adsorbed by the adsorption roller, thereby achieving timely cleaning of the flocculent residues entangled in the gaps between the grid plates.

[0025] Furthermore, the utility model supplies power to the conductive roller core according to a preset time period through a power controller. It can be understood that when static electricity exists on the surface of the adsorption roller, the flocculent residues accumulate on the adsorption roller and aggregate into flocculent aggregates with heavier weight. When the power controller cuts off the power supply to the adsorption roller, the flocculent aggregates with heavier weight will fall stably into the recovery cabin due to gravity, thereby preventing the flocculent residues with lighter weight from floating unstably in the air and causing pollution, thereby achieving the stability of the effect of cleaning the flocculent residues entangled in the gaps between the grid plates.

[0026] Furthermore, the utility model produces an oscillating effect on the grid plate through the off-axis rotation of the oscillation roller, thereby shaking off a small amount of residue that is difficult to clean directly through electrostatic adsorption into the recovery chamber, thereby achieving a stable effect of cleaning the flocculent residue entangled in the gaps between the grid plates.

Figure 2 This is a side view of an intelligent screen slag processing device according to an embodiment of the utility model. An intelligent screen slag processing device according to the utility model comprises:

[0037] The machine body comprises a support frame 1 and traction mechanisms respectively arranged on both sides of the support frame 1, wherein the traction mechanism comprises a sprocket 2 and an annular chain 3 meshed with the sprocket 2;

[0038] The annular grid plate comprises a plurality of rectangular mesh plates 4, and both ends of each rectangular mesh plate 4 are connected to the annular chain 3, so that the annular chain 3 drives each rectangular mesh plate 4 to rotate;

[0039] The residue cleaning mechanism includes a drying roller 5 for drying the residues on each rectangular mesh plate 4, an adsorption roller 6 for generating static electricity to adsorb the residues, and an oscillation roller 7 for oscillating the rectangular mesh plate 4, which are sequentially arranged on the support frame 1 from top to bottom;

[0040] The drying roller 5, the adsorption roller 6 and the oscillation roller 7 are respectively in contact with the rectangular screen plate 4 rotating downward;

[0041] The residue recovery component comprises a recovery chamber 8 arranged at one side of the downwardly rotating rectangular mesh plate 4 for collecting the residues carried by the downwardly rotating rectangular mesh plate 4 and a conveyor arranged at the bottom of the recovery chamber for conveying the residues.

[0042] Specifically, the structure of driving the rectangular mesh plate to rotate upward and downward by an annular chain is a common structure of a grille cleaning machine, which is a prior art and will not be described in detail here.

[0043] In practice, buffer strips 42 are further provided between the connected rectangular mesh plates. The buffer strips 42 may be made of rubber material to prevent wear between the rectangular mesh plates due to contact. This is a prior art and will not be described in detail here.

[0044] Specifically, in the actual sewage treatment process, the intelligent screen residue treatment device of the utility model, the sprocket 2 in the traction mechanism drives the ring chain 3 meshed on the sprocket 2 to rotate, and the two sections of the ring chain 3 on both sides of the support frame 1 run synchronously to drive the rectangular mesh plate 4 arranged between the two sections of the ring chain 3 to rotate upward and downward relative to the sewage liquid surface. During the upward rotation process, the convex hooks on the rectangular mesh plate 4 hook up the impurities in the sewage. During the downward rotation process, the impurities on the rectangular mesh plate 4 are dried by the drying roller 5, passed through the adsorption roller 6 with static electricity on the surface, and finally passed through the oscillation roller 7. During the downward rotation process, the heavier impurities on the rectangular mesh plate 4 fall into the recovery cabin 8 due to gravity factors. The adsorption roller 6 settles the agglomerates of flocculent residues into the recovery cabin 8 by periodically turning on and off the power, and the conveyor at the bottom of the recovery cabin transports the screen residue in the recovery cabin out for subsequent treatment.

[0045] Specifically, the traction mechanism further includes a driving motor 11 connected to the sprocket 2 , and the driving motor 11 drives the sprocket 2 to rotate.

[0046] Specifically, the driving motor 11 may be a DC motor, which is widely used in industrial equipment and will not be described in detail here.

[0047] Specifically, see Figure 3 As shown, it is a partial schematic diagram of a rectangular mesh plate of an embodiment of the utility model. The plate surface of the rectangular mesh plate 4 is provided with a plurality of convex hooks 41 for hooking the residue in the sewage.

[0049] Specifically, the drying roller 5 includes an electric heating tube and a heat-conducting roller body sleeved on the electric heating tube, and the heat-conducting roller body is made of stainless steel.

[0050] Specifically, the utility model dries the residues on each rectangular mesh plate 4 through the drying roller 5. It can be understood that the flocculent residues will be tightly wrapped in the gaps between the grid plates when wet. This is because the presence of water makes it have a certain viscosity. After being dried by the drying roller 5, the moisture in the flocculent residues is removed, and its viscosity is greatly reduced, thereby making the flocculent residues dry and loose, and easier to remove.

[0051] Specifically, the adsorption roller 6 includes a conductive roller core for adsorbing residues and an insulating layer sleeved on the conductive roller core, and the insulating layer is made of rubber.

[0052] Specifically, the utility model adsorbs residues through the adsorption roller 6 that can generate static electricity, and the structure of the flocculent residues after drying becomes looser. When the adsorption roller 6 generates an electrostatic field, the larger surface area of ​​the flocculent residues in a dry state can make more charges distributed on the surface of the residues, making it easier to be adsorbed by the adsorption roller 6, thereby achieving timely cleaning of the flocculent residues entangled in the gaps between the grid plates.

[0053] Specifically, the conductive roller core is connected to a power controller, and the power controller is used to supply power to the conductive roller core according to a preset time period.

[0054] In implementation, the duration of the preset time period may be 1-3 hours. Preferably, the duration of the preset time period is set to 1.5 hours, that is, the power controller controls the conductive roller core to be powered off once every 1.5 hours.

[0055] Specifically, the utility model supplies power to the conductive roller core according to a preset time period through a power controller. It can be understood that when static electricity exists on the surface of the adsorption roller 6, the flocculent residues accumulate and aggregate on the adsorption roller 6 to form flocculent aggregates with heavier weight. When the power controller cuts off the power supply to the adsorption roller 6, the flocculent aggregates with heavier weight will fall stably into the recovery cabin 8 due to gravity factors, thereby preventing the flocculent residues with lighter weight from floating unstably in the air and causing pollution, thereby achieving the stability of the effect of cleaning the flocculent residues entangled in the gaps between the grid plates.

[0056] Specifically, see Figure 4 As shown, it is a simplified structural diagram of an oscillating roller according to an embodiment of the utility model. The oscillating roller 7 includes an oscillating roller body 71 and a roller shaft 72 , and the axis of the roller shaft 72 does not coincide with the axis of the oscillating roller body 71 .

[0057] Specifically, the utility model produces an oscillating effect on the grid plate through the eccentric rotation of the oscillation roller 71, shaking off a small amount of residue that is difficult to clean directly by electrostatic adsorption into the recovery chamber 8, thereby achieving a stable effect of cleaning the flocculent residue entangled in the gaps between the grid plates.
