Description

Technical Field

[0001] This invention relates to the field of sludge reduction technology, specifically to a sludge reduction packing box device for co-processing solid waste sludge in cement kilns. Background Technology

[0002] Sludge generated during wastewater treatment plant operation has a high water content and complex composition, containing large amounts of organic matter, pathogens, and heavy metals. It possesses the dual attributes of "resource" and "pollution," making sludge reduction a crucial aspect of environmental governance. Cement kiln co-processing of sludge takes place in a high-temperature, strongly alkaline environment, thoroughly decomposing the organic matter in the sludge, killing all pathogens, and effectively solidifying heavy metals within the mineral lattice of cement clinker to form a stable solid solution, significantly reducing their leaching toxicity and migration. The SiO2, Al2O3, and Fe2O3 in the sludge ash are precisely the silica, alumina, and ferrous corrective materials required for cement clinker production, and can partially replace natural clay and sandstone. The organic matter in the sludge has a certain calorific value and can be used as an alternative fuel, reducing fossil fuel consumption and lowering carbon emissions and costs in cement production. The packing box device, as the core processing equipment, constructs a sludge flow and reaction space through its internal packing structure, achieving the decomposition or particle separation of organic components in the sludge, thus reducing its volume. This device needs to be adapted to the special working conditions of cement kilns, such as high temperature, high corrosion, and high particle concentration, to ensure structural stability and smooth flow. It is the core carrier for ensuring the efficiency of sludge reduction.

[0003] Existing technologies, such as the Chinese patent announcement number CN105776789A, disclose a micro-animal sludge reduction packing box device designed specifically for sludge from conventional sewage treatment plants. However, when applied to the treatment of cement kiln solid waste sludge, it suffers from key defects that do not meet the core requirements. Specifically: First, it lacks a targeted anti-clogging design for the sludge inlet channel. Coarse particles in cement kiln sludge can easily block the pores of the packing, and the sludge inlet path is not directionally guided, causing particles to accumulate randomly at the packing joints, preventing the sludge from entering the packing to participate in the reduction reaction. Second, the packing connection structure is unstable. Using adhesive or snap-fit ​​connections, it is easily displaced by water flow impact, causing deformation and misalignment of the flow pores between the packing, further exacerbating the blockage of the sludge inlet channel. Moreover, after displacement, it is impossible to form a regular sludge inlet hole positioning, making subsequent cleaning difficult to implement accurately. Summary of the Invention

[0004] The purpose of this invention is to provide a reduced-volume packing box device for co-processing solid waste sludge in cement kilns, so as to solve the problems mentioned in the background art.

The inlet is connected to the internal pores of the flat plate support packing and is used to guide the cement kiln solid waste sludge into the pores of the flat plate support packing. The cleaning unit is installed on the vertical support packing.

[0007] Preferably, a transmission gear is provided on one side of the cleaning unit, and the transmission gear is fixedly connected to the female locking pin. After the vertical support packing and the flat plate support packing are installed together, the female locking pin is connected to the female locking pin. The transmission gear meshes with the drive gear. A rack is provided at the bottom of the cleaning unit, and the drive gear meshes with the rack. A cleaning plate is also provided on the cleaning unit, and the cleaning units are connected to each other through connecting plates.

[0008] Preferably, one end of the male locking pin has a hollow cavity, in which a first spring is provided and a connecting cap is fixedly connected. The female locking pin and the male locking pin also have hollow cavities at their mating ends. When mating, the connecting cap enters the hollow cavity. A locking block is provided on the outer side of the connecting cap, and a locking groove adapted to the locking block is provided on the inner wall of the female locking pin.

[0009] Preferably, the male locking pin and the female locking pin are connected to form a drive shaft. One end of the drive shaft is connected to a drive gear, and the other end passes through the back of the main frame and is connected to a pulley. The pulley is driven to rotate by a servo motor, and multiple pulleys are driven by belt strips.

[0010] Preferably, the sewage discharge unit includes a turntable, a spiral blade, a bevel gear set, a connecting shaft, and a spur gear set. The servo motor drives the connecting shaft to rotate through the spur gear set, and the connecting shaft drives the spiral blade to rotate through the bevel gear set.

[0011] Preferably, a valve is provided at one end of the inner cavity of the bottom fixing groove, the inner cavity of the bottom fixing groove is inclined downward toward the valve, and an installation hole is provided on the bottom wall of the bottom fixing groove directly below the valve. A control unit is provided in the inner cavity of the installation hole. The valve is opened by moving the control unit upward to allow the mud and water in the inner cavity of the bottom fixing groove to pass through.

[0012] Preferably, the control unit includes a sleeve, a support column, and a second spring. The inner cavity of the sleeve is provided with the second spring, and the top end of the second spring is connected to the support column. The side wall of the sleeve is provided with a locking block, and the side wall of the support column is provided with a locking groove. The locking block and the locking groove are mutually compatible.

[0013] Preferably, a movable plate is fixedly connected to the bottom of the sleeve. The movable plate is located at the bottom of the bottom fixed groove. A turntable is provided at one end of the spiral blade. Multiple protrusions are provided on the outside of the turntable. When the turntable rotates, the protrusions strike the movable plate, causing the sleeve to move upward.

[0014] Preferably, the top of the support column abuts against the bottom of the valve, the second spring is in a compressed state in its natural state, the support column does not press against the valve, the valve remains closed, and when the turntable rotates continuously, the protrusions repeatedly hit the movable plate, driving the sleeve to reciprocate up and down, thereby realizing the intermittent opening and closing of the valve.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the cleaning unit performs targeted cleaning of the sludge inlet hole, promptly removing coarse particles accumulated inside the hole, ensuring that the sludge smoothly enters the packing pores through the sludge inlet hole to participate in the reduction reaction. This achieves the technical effects of preventing blockage of the dedicated sludge inlet channel and regularizing the sludge flow path, ensuring efficient contact between cement kiln solid waste sludge and packing, and providing a stable flow foundation for the continuous development of the sludge reduction reaction. 2. In this invention, through the cooperation of guide rail, sliding locking block and locking pin, the locking pin automatically pops out and locks after the flat plate support packing is inserted along the guide rail, so as to realize the stable connection of the packing and the precise positioning of the sludge inlet hole. This allows the cleaning unit to target and clean each sludge inlet hole, achieving the technical effect of long-term stable packing structure and precise positioning of sludge inlet hole, ensuring that the anti-clogging function of the cleaning unit is covered without dead corners, and further improving the continuity and stability of sludge flow. 3. In this invention, the sewage discharge unit and valve are linked by a gear set. The drive motor of the cleaning unit synchronously drives the sewage discharge unit to operate and open the valve. The directional water flow gathers and scrapes off the particles before being discharged through the channel. When not cleaning, the valve remains closed, achieving the technical effect of timely discharge of particles and no continuous loss of mud and water, and avoiding secondary accumulation of particles after cleaning.

[0018] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1-2 As shown in the figure, this embodiment discloses a reduction packing box device for co-processing solid waste sludge in cement kilns, including a main frame 100, vertical support packing 200, and flat support packing 300. The main frame 100 is a square structure formed by multiple support frames, and multiple aerators 110 are provided at the bottom of its inner cavity. The vertical support packing 200 is stacked in sequence in the inner cavity of the main frame 100, and the flat support packing 300 is stacked in sequence on one side of the vertical support packing 200.

[0021] Furthermore, in existing reduction packing box devices, such as the one described in Chinese Patent Publication No. CN105776789A, when applied to the treatment of cement kiln solid waste sludge, coarse particles in the sludge easily block the pores of the packing, and the sludge inlet path is not directionally guided, causing particles to accumulate randomly at the packing joints, resulting in the sludge being unable to enter the packing to participate in the reduction reaction.

[0022] To solve this problem, such as Figure 2As shown, a baffle plate 310 is provided on one side of the flat plate support packing 300 to block sludge. The baffle plate 310 has a sludge inlet hole 311 on its surface, which is connected to the internal pores of the flat plate support packing 300. This guides the cement kiln solid waste sludge into the pores of the flat plate support packing 300, allowing the sludge to participate in the reduction reaction. More specifically, by setting the baffle plate 310 with the directional sludge inlet hole 311, the traditional surface-flowing sludge feeding method of the packing is changed to directional flow. This forces large particles in the cement kiln sludge to be pre-distributed on the surface of the baffle plate, allowing only particles smaller than the sludge inlet hole 311 to enter the internal reaction zone of the packing. This achieves primary anti-clogging from a physical structure perspective.

[0023] To prevent the inlet hole 311 from becoming clogged, such as Figure 3 As shown, a cleaning unit 230 is installed on one side of the vertical support packing 200. The cleaning unit 230 corresponds to the baffle plate 310. After the vertical support packing 200 and the flat support packing 300 are connected and installed, the cleaning unit 230 is moved laterally to wash the surface of the flat support packing 300, remove particles attached to the inlet hole 311, and prevent the inlet hole 311 from becoming blocked. This allows sludge to enter the pores of the flat support packing 300 through the inlet hole 311 and participate in the subsequent reduction reaction. The cleaning units 230 in a vertical row are connected to each other through the connecting plate 240, so that the cleaning units 230 can move simultaneously to clean the inlet hole 311.

[0024] like Figure 4 As shown, a transmission gear 231 is provided on one side of the cleaning unit 230, and a drive gear 232 meshes with the bottom of the transmission gear 231. A rack 233 is provided at the bottom of the cleaning unit 230. The transmission gear 231 and the drive gear 232 mesh with each other, and the drive gear 232 meshes with the rack 233. By controlling the rotation of the transmission gear 231, the drive gear 232 rotates. Through the meshing of the drive gear 232 and the rack 233, the cleaning unit 230 moves laterally when the drive gear 232 rotates. The lateral movement of the cleaning unit 230 drives the cleaning plate 234 to move, and the reciprocating movement of the cleaning plate 234 cleans the dirt inlet holes 311 along its path, removing particulate matter. Figure 4 and Figure 7As shown, when the vertical support packing 200 and the flat support packing 300 are locked together by the female locking pin 220 and the male locking pin 330, the male locking pin 330 and the female locking pin 220 together form a continuous drive shaft. One end of this drive shaft is connected to the drive gear 231 of the cleaning unit 230, and the other end extends to the outside of the main frame 100 and is connected to the pulley 130. This allows the servo motor 120 to drive the drive shaft to rotate via the belt, which in turn drives the drive gear 231 to rotate. Finally, through the meshing of the drive gear 232 and the rack 233, this is converted into the lateral reciprocating motion of the cleaning unit 230.

[0025] Continue as Figure 3 As shown, to ensure successful installation and one-to-one correspondence between all vertical support packings 200 and flat support packings 300, guide rails 210 are provided on both sides of the vertical support packings 200. Female locking pins 220 are respectively provided on both sides of the inner wall of the guide rails 210. Sliding locking blocks 320 are respectively provided on both sides of the flat support packings 300. The female locking pins 220 and the sliding locking blocks 320 are mutually compatible. During installation, the guide rails 210 and sliding locking blocks 320 can be slidably connected. Sub-locking pins 330 protruding from both sides are fixedly installed on the sliding locking blocks 320. After the guide rails 210 and sliding locking blocks 320 are connected, the two ends of the sliding locking blocks 320 are embedded in the inner cavity of the female locking pins 220, thus locking the positions of the vertical support packings 200 and flat support packings 300, completing the installation.

[0026] like Figure 5 As shown, the end of the sub-locking pin 330 has a hollow cavity, inside which a first spring 331 is provided, and a connecting cap 332 is connected through the first spring 331. When the sliding locking block 320 slides along the guide rail 210, the connecting cap 332 is squeezed and moved backward, causing the first spring 331 to deform. When the sub-locking pin 330 moves to the female locking pin 220, the first spring 331 rebounds, causing the connecting cap 332 to be embedded in the inner cavity of the female locking pin 220. A locking block 333 is provided on the outer side of the connecting cap 332, and a locking groove adapted to the locking block 333 is provided on the inner wall of the female locking pin 220, so that the connecting cap 332 is fixed, that is, the vertical support packing 200 and the flat support packing 300 are connected, and the sub-locking pin 330 and the sliding locking block 320 form a drive shaft.

[0027] like Figure 4 , Figure 6As shown, one end of the transmission shaft, which is composed of the sliding locking block 320 and the sub-locking pin 330, is fixedly connected to the transmission gear 231. The other end of the transmission shaft is connected to the pulley 130. The pulleys 130 are driven to rotate by the belt strip and the servo motor 120 provides power to drive the pulleys 130 to rotate. After the vertical support packing 200 and the flat support packing 300 are installed together, the cleaning unit 230 is driven by the pulley 130 to clean the dirt inlet hole 311 provided on each flat support packing 300.

[0028] like Figure 8 As shown, a bottom fixing groove 400 is provided below the main frame 100. A sewage ditch 410 is provided at the top of the bottom fixing groove 400. A filter screen 420 is provided at one end of the bottom wall of the sewage ditch 410, and the bottom wall of the sewage ditch 410 is inclined downward toward the filter screen 420. This allows the mud and water to slide onto the sewage ditch 410 and onto the filter screen 420, and then enter the inner cavity of the bottom fixing groove 400 through the filter screen 420. The filter screen 420 intercepts coarse particles such as kiln slag and large solid waste in the cement kiln sludge, preventing large particles from entering subsequent pipes, pumps or treatment units, causing pipe blockage and equipment wear.

[0029] like Figure 9 As shown, a valve 430 is provided at one end of the inner cavity of the bottom fixing groove 400. The inner cavity of the bottom fixing groove 400 is inclined downward toward the valve 430, so that the mud and water entering the bottom fixing groove 400 can be discharged through the valve 430. The bottom wall of the main frame 100 is provided with a mounting hole 450 directly below the valve 430. A control unit 440 is installed in the inner cavity of the mounting hole 450. By moving the control unit 440 upward to lift the valve 430, the mud and water can be discharged through the valve 430.

[0030] like Figure 7 As shown, the drive end of the servo motor 120 drives the connecting shaft 540 through a spur gear set 550. One end of the connecting shaft 540 drives the spiral blade 520 through a bevel gear set 530. The servo motor 120 drives the spiral blade 520 to rotate. When the spiral blade 520 rotates, the spiral surface of the blade will squeeze and cut the mud and water in the box. The rotation of the spiral blade generates axial thrust, forming a downward directional water flow, which allows the mud and water to enter the bottom fixed groove 400 (where the spiral blade 520 is located in the vertical cylinder at the center of the bottom of the main frame 100 (in conjunction with...) Figure 6 and Figure 7As shown), the upper end of the vertical cylinder is connected to the packing area, and the lower end is connected to the sludge flow channel 410 of the bottom fixed groove 400, so that the rotation speed of the spiral blade 520 can be adjusted according to the servo motor 120 to adapt to different sludge viscosities. The surface of the spiral blade 520 can be coated with a wear-resistant and anti-corrosion coating. The spiral blade 520 and the cleaning unit 230 are driven by the servo motor 120 at the same time. Specifically, when the cleaning unit 230 cleans the sludge inlet hole 311 on the flat plate support packing 300, the spiral blade 520 rotates synchronously, so that the cleaned residue enters the inner cavity of the bottom fixed groove 400 through the directional water flow. Specifically, the vertical support packing 200 has a through shaft hole inside. The male locking pin 330 and the female locking pin 220 are connected to form a continuous transmission shaft. The transmission shaft is supported in the shaft hole by bearings and prevents sludge from entering through the sealing ring. One end of the transmission shaft is keyed to the transmission gear 231, and the other end extends to the outside of the main frame 100 and is connected to the pulley 130.

[0031] like Figure 10 As shown, the control unit 440 includes a sleeve 441, a support column 442, and a second spring 443. The second spring 443 is installed inside the sleeve 441 and is fixedly connected to the support column 442. A locking block 444 is installed on the outer side of the sleeve 441. A slot 445 that matches the locking block 444 is opened on the outer side of the movable plate 446. A turntable 510 is installed at the other end of the spiral blade 520. Multiple protrusions are provided on the outer side of the turntable 510. A movable plate 446 is installed at the bottom of the sleeve 441 and is located at the bottom of the bottom fixing groove 400. When the turntable 510 rotates with the spiral blade 520, the protrusions hit the movable plate 446, causing the movable plate 446 to move upward, which in turn moves the sleeve 441 upward. When the locking block 444 leaves the inner cavity of the mounting hole 450, the locking block 444... 4. Unobstructed, the bottom of the locking block 444 is set as an inclined surface. Under the action of the second spring 443, the support column 442 disengages from the limit of the locking groove 445 and pushes the valve 430 upward. Under the elastic force of the second spring 443, the support column 442 moves upward and pushes the valve 430 to open the mud and water outflow channel. When the spiral blade 520 stops rotating, the movable plate 446 returns to its original position, and the locking block 444 returns to the inner cavity of the mounting hole 450. The support column 442 slowly falls back under the gravity of the valve 430, closing the mud and water outflow channel. More specifically, the valve 430 adopts a sinking sealing structure. Its own weight may be increased by adding a lightweight counterweight to ensure that when the support column 442 moves downward, it can rely on its own weight to overcome the remaining elastic force of the second spring 443 and the static pressure of the mud and water to close the flow channel. In this process, the continuous rotational power generated by the spiral blades 520 enables automatic and intermittent sewage discharge, eliminating the need for additional electrical control components such as solenoid valves that are easily corroded by sludge, thus improving the overall reliability of the device under harsh working conditions.

[0032] The entire system integrates the packing locking mechanism (composed of the male locking pin 330 and the female locking pin 220) with the cleaning mechanism (composed of the cleaning unit 230, drive gear 232, rack 233, and cleaning plate 234). This design automatically assembles and positions the drive chain of the cleaning unit 230 during each packing installation and locking. This not only ensures precise alignment of the pores between multiple packing groups, forming a stable sludge inlet channel, but also utilizes the same power source (servo motor 120) to synchronously drive cleaning and sludge discharge, achieving highly efficient coordination of installation-in-positioning and operation-in-cleaning. This fundamentally solves the structural failure problem caused by packing displacement or blockage. Simultaneously, the spiral blades 520 generate directional water flow, enabling the rotational power to be transmitted to the turntable 510 and the protrusion, converting it into the mechanical force controlling the intermittent opening of the valve 430. Thus, it achieves highly efficient operation with a single power input and coordinated cleaning and sludge discharge, solving the problems caused by blockage, displacement, and control failures in cement kiln sludge reduction devices.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. The present invention is not limited to the above embodiments; the embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
