[0004] However, although this technical solution can convey the charge obliquely into the furnace by crushing the charge, during the conveying process, the charge is relatively loose, which easily causes the combustion smoke in the furnace to be discharged back toward the conveying channel and the feed inlet. Moreover, when the humidity of the incineration charge is high, it is not convenient to complete the drainage of the charge while conveying it. Summary of the invention

The sealing and blocking parts first move to a state flush with the variable-diameter cylinder, and the sealing and pressing parts scrape the residual charge at the end of the sealing and blocking parts to the variable-diameter screw section, so that the moisture discharged from the compressed charge is discharged through the water filter channel, and when the sealing and pressing parts continue to evacuate in the reverse direction, the reverse push part generates air force in the reverse direction to clean the hole in the water filter channel, and when the diameter is reduced to the sealing cylinder to enter the flux, it enters the sealing cylinder to block the smoke, and continues to be guided to the unloading assembly through the small-diameter screw part, scrapes the hardened charge to the loosening discharge assembly, and switches back and forth between the loosening assembly and the pushing assembly, while completing the loosening treatment of the hardened charge, it is pushed out of the furnace chamber, so as to solve the technical problems described in the background technology.

Thus, the features defined with "major diameter" and "diameter variation" may explicitly or implicitly include one or more of such features.

[0041] Embodiment 1

[0042] As Figure 1 and 2As shown in the figure, a leakage-proof air supply system for a waste incinerator feed includes a furnace body 1. A furnace chamber 11 is provided inside the furnace body 1. The system further includes: a material pressing and guiding assembly 2 for filtering water and compressing the furnace material and guiding it into the furnace body 1. The material pressing and guiding assembly 2 is installed on the furnace body 1; and a material loosening and discharging assembly 3 for loosening the compressed furnace material and pushing the loosened furnace material into the furnace chamber 11. The material loosening and discharging assembly 3 is installed on one side of the furnace chamber 11.

[0043] It is not difficult to find from the above content that during the process of transporting and incinerating waste materials into the furnace chamber 11, when the waste furnace material is guided through the material pressing and guiding assembly 2, while continuously outputting the transported furnace material, compression treatment is carried out to discharge the moisture in the compressed furnace material. At the same time, the relatively dense structure formed by the compressed waste can effectively block the backflow of flue gas in the furnace during the continuous transportation into the furnace body 1. When the material pressing and guiding assembly 2 continuously transports to the material loosening and discharging assembly 3, the material loosening and discharging assembly 3 will loosen the compressed furnace material and push it into the furnace chamber 11 for incineration after the treatment.

[0044] As Figure 3 As shown in the figure, the material pressing and guiding assembly 2 includes: a screw assembly 21 for variably-diameter conveying of the furnace material; a feed bin 22 for temporarily storing the loaded furnace material. The feed bin 22 is provided at the input end of the screw assembly 21; a material pressing assembly 23 for variably-diameter compressing and filtering water of the furnace material conveyed on the screw assembly 21 and then outputting it. The material pressing assembly 23 is provided on one side of the feed bin 22; and a material cleaning assembly 24 for hermetically outputting the filtered water furnace material and discharging the material at the conveying end of the screw assembly 21. The material cleaning assembly 24 is provided on one side of the end of the screw assembly 21. The screw assembly 21 conveys the furnace material in the feed bin 22 to the material pressing assembly 23. The material pressing assembly 23 compresses and drains the furnace material variably-diameter conveyed by the screw assembly 21 and then outputs it hermetically through the material cleaning assembly 24. The material cleaning assembly 24 discharges and cleans the material at the hermetically output end of the screw assembly 21.

[0045] In this embodiment, during the process of compressing and draining water from the furnace material by the material pressing and guiding assembly 2, the screw assembly 21 rotating in the feed bin 22 conveys the loaded furnace material into the material pressing assembly 23. The material pressing assembly 23 squeezes the furnace material along the circumferential direction of the screw assembly 21 to achieve the drainage treatment of the furnace material. And to solve the problem of backflow of flue gas during the transportation of the furnace material, the screw assembly 21 is subjected to a diameter reduction treatment to reduce the radial dimension during the material conveying of the screw assembly 21. Then, by outputting the compressed furnace material, the technical problem of backflow of flue gas in the furnace body 1 can be effectively solved. When the compressed furnace material is transported to the material cleaning assembly 24 after compression, the material cleaning assembly 24 cleans the compressed furnace material exported from the screw assembly 21 and drops it onto the material loosening and discharging assembly 3 for loosening and discharging treatment of the furnace material.

[0046] As shown Figure 9 in the figure, the screw component 21 includes: a large-diameter screw section 211 correspondingly inserted into the bin 22; a variable-diameter screw section 212, and the variable-diameter screw section 212 with a gradually decreasing radial dimension along the axial direction is correspondingly arranged with the pressure-feeding component 23; and a small-diameter screw section 213, and the small-diameter screw section 213 connected to the end of the variable-diameter screw section 212 is correspondingly arranged with the material-cleaning component 24.

[0047] In this embodiment, during the continuous feeding process, the large-diameter screw section 211 at the forefront is used to drive the furnace charge grabbed and released into the bin 22 by the hanging claws to be sent into the pressure-feeding component 23. The pressure-feeding component 23 reciprocally extrudes the furnace charge conveyed by the variable-diameter screw section 212, so as to realize extruding the furnace charge into a relatively dense structure, squeezing out the moisture in the furnace charge, and making the furnace charge conveying space continuously reduce in diameter and become more compact. Thus, when the furnace charge is output through the material-cleaning component 24, the dense furnace charge can be used to block the backflow of the exhaust gas generated when the furnace charge burns in the furnace body 1. Moreover, when the small-diameter screw section 213 outputs the furnace charge, by using the material-cleaning component 24, the furnace charge on the small-diameter screw section 213 can also be scraped off and discharged to the loosening area of the material-loosening and discharging component 3 for the loosening treatment of the furnace charge.

[0048] It should also be supplemented that, as shown Figure 1 in the figure, a feeding motor 214 with a power end connected to the large-diameter screw section 211 is installed on the bin 22, and the feeding motor 214 is preferably a servo motor.

[0049] As shown Figures 4 - 6 in the figure, the pressure-feeding component 23 includes: a variable-diameter cylinder body 231 arranged along the axial direction of the variable-diameter screw section 212; a pressure-filtering part 232 arranged along the circumferential direction of the variable-diameter screw section 212 and slidably arranged in the variable-diameter cylinder body 231 along the radial direction of the variable-diameter screw section 212; a pressure-feeding power part 233 for driving the pressure-filtering part 232 to move back and forth in the radial direction of the variable-diameter screw section 212; and a water-guiding component 234 installed on one side of the bottom of the variable-diameter cylinder body 231; a water-filtering channel 23211 corresponding to the water-guiding component 234 is provided in the bottom group of the pressure-filtering parts 232.

[0050] In this embodiment, during the process of the blanking component 23 compressing and draining the furnace charge on the variable-diameter screw section 212 and adjusting the flux when conveying the furnace charge into the furnace body 1, when the furnace charge continuously conveys to the cleaning component 24 on the variable-diameter screw section 212, the filter pressing member 232 between the variable-diameter cylinders 231 continuously extrudes the furnace charge along the variable-diameter oblique direction of the variable-diameter screw section 212 towards the variable-diameter screw section 212, so as to continuously compress the furnace charge into one end of the variable-diameter screw section 212 with the smallest radial dimension. And the flux corresponding to this end of the variable-diameter screw section 212 is the smallest when the filter pressing member 232 is compressed to the maximum. And during the process of the filter pressing member 232 compressing the furnace charge, the compressed water will be discharged into the water guiding component 234 through the water filtering channel 23211 opened on the lowermost filter pressing member 232 and then further discharged outside in the water guiding component 234.

[0051] As Figure 5 shown, the filter pressing member 232 includes: a sealing and pressing member 2321 arranged circumferentially; and a sealing and blocking member 2322 disposed between adjacent sealing and pressing members 2321 and slidably corresponding to the side wall of the variable-diameter cylinder 231; the blanking power member 233 drives the sealing and blocking member 2322 to move towards the variable-diameter screw section 212 until it is flush with the inner side wall of the variable-diameter cylinder 231, and then drives the sealing and pressing member 2321 to move along this flush surface towards the variable-diameter screw section 212 to extrude the furnace charge.

[0052] In this embodiment, during the process of the filter pressing member 232 compressing the furnace charge around the variable-diameter screw section 212, the blanking power member 233 will first drive the sealing and blocking member 2322 with a triangular end to reach the maximum compression position. And at this maximum compression position, the two sides of the triangular end of the sealing and blocking member 2322 are respectively flush with the side wall of the variable-diameter cylinder 231, thus jointly forming a guiding channel for the sealing and pressing member 2321 to move back and forth. Subsequently, the blanking power member 233 drives the sealing and pressing member 2321 with an arc-shaped end to fully extrude the furnace charge, so that the furnace charge is compressed and the water is squeezed out.

[0053] As Figure 6 and 8 shown, the water guiding component 234 includes: a water conveying channel 2341 arranged on the variable-diameter cylinder 231 corresponding to the bottom group of sealing and pressing members 2321; and anti-pushing members 2342 uniformly distributed on the inner wall of the water conveying channel 2341 and corresponding to the water filtering channels 23211; when the sealing and pressing member 2321 moves downward, the anti-pushing member 2342 is inserted into the water filtering channel 23211 and generates air pressure on the top of the water filtering channel 23211. When the sealing and pressing member 2321 moves upward, the anti-pushing member 2342 leaves the bottom of the water filtering channel 23211, and the squeezed water enters the water conveying channel 2341 through the water filtering channel 23211.

[0054] In this embodiment, during the discharge of the compressed water, by using the water delivery channel 2341, the water extruded from the water filtering channel 23211 can be centrally discharged. And to better ensure the water permeability of the water filtering channel 23211, when the sealing and pressing member 2321 moves towards the variable diameter screw section 212, the reverse pushing member 2342 will move along the water filtering channel 23211 and gradually leave the water filtering channel 23211. When the sealing and pressing member 2321 continues to greatly extrude the furnace charge, the water is extruded and discharged into the water delivery channel 2341 through the water filtering channel 23211. When the sealing and pressing member 2321 moves in the reverse direction, the reverse pushing member 2342 continues to insert into the water filtering channel 23211 and acts on the other end of the water filtering channel 23211 through reverse air pressure, so as to clean the blocking situation of the furnace charge at the other end of the water filtering channel 23211.

[0055] It should be added that, as Figure 4 shown, the material pressing power member 233 includes a driving disk assembly 2331 for respectively driving the sealing and pressing member 2321 and the blocking member 2322 to move back and forth along the guiding side wall of the variable diameter cylinder 231, guiding wheels 2332 opened on both sides of the driving disk assembly 2331, a guide wheel bracket 2333 connected to one end of the variable diameter cylinder 231 and arranged along the axial direction of the screw assembly 21, a driving shaft 2335 installed on the variable diameter cylinder 231, a driving gear 2334 installed on the driving shaft 2335 and in transmission engagement with the driving disk assembly 2331, and a power motor 2336 installed on the variable diameter cylinder 231 and with the power end connected to the driving shaft 2335. The power motor 2336 is preferably a servo motor.

[0056] It also needs to be added that the driving disk assembly 2331 includes a toothed disk body 23311, a first guiding channel 23312 opened on one side of the toothed disk body 23311, a first guiding block 23314 arranged in the first guiding channel 23312 and connected to the blocking member 2322, a second guiding channel 23315 opened on the other side of the driving disk assembly 2331, a second guiding block 23317 slidably arranged in the second guiding channel 23315 and connected to the sealing and pressing member 2321. The first guiding channel 23312 includes a first raised channel 23313 bulging towards the center of the toothed disk body 23311, the second guiding channel 23315 includes a second raised channel 23316 bulging towards the center of the toothed disk body 23311, and the guiding arc length of the first raised channel 23313 is greater than the guiding arc length of the second raised channel 23316.

[0057] In this embodiment, during blanking, the first guiding block 23314 will reach the first convex channel 23313 in advance, so that the blocking member 2322 reaches the state flush with the variable-diameter cylinder 231 in advance. Subsequently, the second guiding block 23317 reaches the second guiding channel 23315 and pushes the blanking and pressing member 2321 towards the side of the furnace charge, so that the blanking and pressing member 2321 forms extrusion on the furnace charge.

[0058] As Figure 10 shown, the blanking component 24 includes: a blanking cylinder 241 arranged through the small-diameter screw section 213; and a blanking component 242 installed on one side of the blanking cylinder 241 for cleaning the screw component 21.

[0059] In this embodiment, after the furnace charge is subjected to variable-diameter compression treatment by the variable-diameter screw section 212, it enters the blanking cylinder 241 through the small-diameter screw section 213 and continuously outputs to the blanking component 242. When outputting in the blanking cylinder 241, since the furnace charge is compressed, it can effectively block the furnace fire and flue gas. And when reaching one side of the small-diameter screw section 213 to the blanking component 242, the blanking component 242 will intermittently clean the furnace charge.

[0060] As Figure 11 shown, the blanking component 242 includes: a sleeve cover 2421 arranged along the axial direction of the screw component 21; a plug 2422 slidably arranged on one side of the sleeve cover 2421 and sequentially inserted into a spiral channel arranged along the axial direction of the screw component 21 and elastically connected to the sleeve cover 2421; and a guiding channel 2423 slidably connected to the plug 2422; the guiding channel 2423 is arranged in a triangular shape; the plug 2422 moves along the guiding channel 2423 towards one side as it rotates with the screw component 21, so that the plug 2422 gradually disengages from the screw component 21 and returns to its original position.

[0061] In this embodiment, when the blanking component 242 cleans the furnace charge on the screw component 21, the furnace charge will be sleeved by the sleeve cover 2421 and inserted into the spiral channel of the screw component 21. When the screw component 21 rotates to bring the material, the plug 2422 moves adaptively in the pushing direction of the spiral channel, and will gradually move away from the spiral channel along the guiding direction of the guiding channel 2423, and under the elastic connection between the plug 2422 and the sleeve cover 2421, it returns to the original position along the other side of the guiding channel 2423 and continues to enter the spiral channel again for scraping treatment.

[0062] It should also be added that, as Figure 11 and 12As shown, the plug-in 2422 includes a plug 24221, a moving block 24222 slidably mounted on the sleeve cover 2421 with the plug 24221 mounted on its side wall, and a guide rod 24223 inserted into the guide channel 2423 with one end mounted on the moving block 24222.

[0063] One side of the moving block 24222 is connected to the sleeve cover 2421 through a spring 242221.

[0064] Embodiment Two

[0065] As Figure 13 shown, the same or corresponding components as those in Embodiment One are denoted by the corresponding reference numerals in Embodiment One. For the sake of simplicity, only the differences from Embodiment One will be described below. The differences between this Embodiment Two and Embodiment One are as follows:

[0066] The loose material discharging assembly 3 includes: a lifting seat 31 disposed below the discharge of the material pressing and feeding assembly 2; a loose material assembly 32 mounted on the lifting seat 31 for loosening the falling furnace charge; and a pushing assembly 33 slidably passing through the furnace body 1 and arranged on one side of the loose material assembly 32; the pushing assembly 33 moves towards the loose material assembly 32, jacking up the lifting seat 31 so that the loose material assembly 32 is disposed above the pushing assembly 33.

[0067] In this embodiment, when the loose material discharging assembly 3 processes the compressed furnace charge cleaned by the blanking assembly 242, when the furnace charge falls onto the loose material assembly 32, the loose material assembly 32 will rotate to process the furnace charge. After the processing, the pushing assembly 33 moves towards the loose material assembly 32, jacks up the loose material assembly 32 along the lifting seat 31, and maintains this jacked-up state. The pushing assembly 33 pushes the furnace charge into the furnace chamber 11. Subsequently, the pushing assembly 33 returns, the loose material assembly 32 continues to move downwards, and the lifting seat 31 cleans the furnace charge that has fallen on the surface of the pushing assembly 33 when it is pushed out. Such reciprocating actions are performed.

[0068] As Figure 13 shown, the lifting seat 31 includes: a retaining seat 311 with one side of the top slidably connected to the furnace body 1; and a guiding seat 312 obliquely arranged on one side of the retaining seat 311 corresponding to the pushing assembly 33.

[0069] In this embodiment, when the pushing assembly 33 moves, it will first jack up the retaining seat 311 and the loose material assembly 32 through the guiding seat 312.

[0070] As Figure 14As shown in the figure, the material loosening assembly 32 includes: material loosening rollers 321 arranged symmetrically, material loosening members 322 evenly distributed on the material loosening rollers 321, a first gear 323 installed on the retaining seat 311 and connected to the material loosening rollers 321, a second gear 324 arranged between the first gears 323 for transmission and meshing, a third gear 325 meshing with one set of the second gears 324, a sealing plate 326 installed on the furnace body 1, and a material loosening motor 327 installed on the sealing plate 326 with its power end connected to the third gear 325. The material loosening motor 327 is preferably a servo motor. The third gears 325 are in even numbers. A sliding space for the up and down movement of the power end of the material loosening motor 327 is provided on the furnace body 1, and the sealing plate 326 always correspondingly seals the sliding space.

[0071] It should be added that the material pushing assembly 33 includes a material pushing seat 331 inserted into the furnace body 1 and a material pushing power member 332 installed outside the furnace body 1 with its power end connected to the material pushing seat 331. The material pushing power member 332 is preferably a cylinder.

[0072] Working steps

[0073] Step 1: Loading. The lifting claws grab the refuse furnace charge and send it into the bin 22, and the large-diameter screw section 211 carries the large-throughput furnace charge into the material pressing assembly 23.

[0074] Step 2: Reducing the diameter of the furnace charge. The furnace charge entering the material pressing assembly 23 is guided from the large-diameter end to the small-diameter end by the variable-diameter screw section 212. After the material pressing power member 233 first drives the blocking member 2322 to move to the maximum stroke position of material pressing, a guiding path for the sealing and pressing member 2321 to move up and down is formed between the triangular end wall of the blocking member 2322 and the variable-diameter cylinder 231. The material pressing power member 233 continues to drive the sealing and pressing member 2321 to extrude towards the furnace charge along the guiding direction of the guiding path. The moisture extruded during the compression of the furnace charge is discharged into the water guiding assembly 234 through the water filtering channel 23211 on the sealing and pressing member 2321 on one side of the bottom.

[0075] Step 3: Reverse dredging. When the reciprocating sealing and pressing member 2321 moves towards the water guiding assembly 234, the reverse pushing member 2342 inserts into the water filtering channel 23211 and generates a reverse air force acting on the other end of the water filtering channel 23211 to push out the blocked filter residue from the water filtering channel 23211.

[0076] Step 4: Blocking and inputting the flue gas. At the same time, under the state that the sealing cylinder 241 with small throughput and dense furnace charge continuously blocks the furnace charge flue gas, the furnace charge is conveyed to the discharging assembly 242.

[0077] Step Five: Scraping. The insert piece inserted into the spiral channel of the screw assembly 21 moves adaptively towards one side when the screw assembly 21 rotates, and gradually leaves the screw assembly 21 along the guiding channel 2423 and returns to the original position to continue entering the spiral channel for cleaning.

[0078] Step Six: Loosening and discharging. The compressed furnace charge falls onto the loosening assembly 32, and after being rotated, broken and loosened by the loosening assembly 32, the pushing assembly 33 moves towards the side of the loosening assembly 32. Under the guiding action of the guiding seat 312, the loosening assembly 32 is jacked up and maintained in this jacked-up state, and the furnace charge is pushed out into the furnace chamber 11. Subsequently, the pushing assembly 33 returns, and the lifting seat 31 scrapes the furnace charge falling on the pushing assembly 33 to the front side of the pushing assembly 33, and this reciprocating action is repeated.

[0079] Step Seven: Incineration. The furnace charge pushed into the furnace chamber 11 is continuously incinerated.

[0080] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
