The injection bottle crusher is used for directly crushing injection glass bottles. The ampoule type glass bottle is a glass bottle (such as a bottle containing penicillin powder) filled with powdered medicines or liquid medicines, is difficult to open manually, and can be directly crushed by an ampoule type bottle crusher. The sorting table is used for manually sorting non-injection glass bottles, and workers stand on a manual sorting position. A worker unscrews the bottle cap of the glass bottle and puts the bottle cap into a packaging collecting basket, and also unloads the package of the glass bottle and puts the glass bottle into the packaging collecting basket; workers need to put non-injection glass bottles into a bottle washing pool for cleaning, break the non-injection glass bottles and put the broken non-injection glass bottles into a glass collecting basket.

Further, the crushing equipment group sequentially comprises a turnover machine, a vibrating feeder, a primary crusher, a secondary crusher, a draining spiral conveyor and a vibrating screening machine according to the direction of material movement; the draining screw conveyor is used for separating the liquid hazardous waste from the solid material; the vibrating screen machine is used for separating bottle caps and cullet.

By adopting the technical scheme, the separation of feeding, crushing, solid-liquid separation and bottle cap and cullet can be realized.

Further, the draining spiral conveyor comprises a conveying cylinder, an included angle is formed between the conveying cylinder and the horizontal plane, a vertically arranged waste liquid pipe is communicated with the bottom end of the conveying cylinder, and a second waste liquid barrel is arranged below the waste liquid pipe; the screen mesh aperture of the vibration screening machine is 8 mm.

The particle size of the cullet formed by two-stage crushing is smaller than 8mm, the diameter of the bottle cap is usually more than 10mm, and the separation of the bottle cap and the cullet can be realized by setting the aperture of the screen to be 8 mm.

Further, the primary crusher and the secondary crusher are hammer crushers, and the secondary crusher is used for obtaining glass particles with the particle size smaller than 8 mm.

By adopting the technical scheme, the hammer type crushing only breaks the glass bottle, the bottle cap cannot be broken, and the bottle cap and the broken glass are separated by the method.

Further, useless processing subsystem of liquid danger is including the head tank, reation kettle and the finished product jar that communicate in proper order, the finished product jar is used for storing the useless finished product of liquid danger that the granularity is less than 2mm, pH value is between 6-9 and the flash point is greater than 60 ℃.

Adopt above-mentioned technical scheme, by the head tank material of keeping in (liquid danger is useless), carry the material in the head tank to reation kettle, can realize the innocent treatment useless to liquid danger, after the processing finishes, place the finished product in the finished product jar, treat next step and handle.

The solid organic matter hazardous waste after impurity removal is subjected to crushing treatment in the crushing unit, and due to the fact that part of inflammable and explosive impurities are possibly not fully removed and the dust in the crushing chamber is large, combustion or explosion easily occurs in the crushing chamber. When burning or explosion takes place, the atmospheric pressure in the crushing chamber expands fast, sets up safe rupture membrane on the crushing chamber and can reach quick pressure release function, avoids the damage of the breaker that internal pressure too big caused. The side wall of the crushing chamber is communicated with a dredging pipe, so that the gas can be guided, and excessive gas is guided to the outside of the crushing chamber. The safety rupture disk is not directly arranged on the side wall of the crushing chamber, but is arranged at one end of the dredging conduit far away from the crushing chamber, so that the safety rupture disk is prevented from being extruded and scratched by materials in the crushing chamber when moving, and the abrasion to the safety rupture disk is reduced.

The product with the particle size smaller than 150mm obtained after the crushing treatment can be fully combusted at the kiln head of the cement kiln, so that the condition that toxic and harmful gases such as dioxin and the like are generated due to insufficient combustion of organic matters is avoided. The product is put into the kiln head of a cement kiln, the particle size of the product is less than 150mm, so that the solid organic hazardous waste finished product can be fully combusted in a certain time (the retention time of the finished product in a high-temperature section of the kiln head is about 15 minutes), and gas meeting the emission standard is formed. The treated solid organic hazardous waste can also be used as fuel to provide heat for the cement kiln.

The solid organic matter danger is useless to use first screening unit, crushing unit and secondary screening unit to handle in proper order in this scheme, and useless the processing becomes the finished product that the particle diameter is homogeneous with danger, and only contains the organic matter in handling this finished product through screening many times, can guarantee the stability and the homogeneity of the physical and chemical properties of solid organic matter finished product, can regard as a standardized product (fire value batch stability), burns at the kiln head of cement kiln. The treatment of dangerous waste in the prior art is usually carried out by simple classification and then combustion treatment. However, after simple classification, the solid organic matter hazardous waste is directly combusted, so that the hazardous waste is insufficiently combusted, and a large amount of harmful gas is generated. In addition, the part with recycling value in the hazardous waste is not comprehensively utilized (can be used as fuel), and the hazardous substances are not completely removed by simple classification and unified combustion treatment, so that the combustion of the hazardous substances can bring about more serious environmental pollution. This scheme has taken the useless processing theory of more advanced danger, will endanger useless and will be handled into standardized product with the useless harmless treatment when useless, and this standardized product has properties such as stable burning value, when carrying out combustion treatment to standardized product, can accurately learn the relation of the quantity of standardized product and the energy that its burning produced.

Each of the processing units is described in detail below:

first, useless processing subsystem of solid inorganic matter danger

The solid inorganic matter dangerous waste treatment subsystem comprises a pre-sorting equipment group and a crushing equipment group. The glass bottles and other solid inorganic hazardous wastes are firstly screened in a pre-sorting equipment set and then crushed in a crushing equipment set. The operation of pre-sorting equipment group and crushing equipment group can generate liquid hazardous wastes, and the liquid hazardous wastes are conveyed to a liquid hazardous waste treatment subsystem to be subjected to harmless treatment. In this example, the solid inorganic hazardous waste is the hazardous waste contained in HW02, HW03 and HW49 from the national hazardous waste catalogue. More specifically, the solid inorganic hazardous wastes are mainly: glass bottles and glass containers (raw material components mainly comprise glass bottle solid inorganic substances and are generally noncombustible) contaminated by HW02 medical wastes, HW03 waste medicines, waste medicines and the like. The solid inorganic hazardous wastes comprise small-size (less than or equal to 50ml) glass bottles and medicines, reagents and the like which cannot be separated from the bottles. The medicine and reagent separated by the method comprise powder (penicillin, streptomycin, phenobarbital sodium, trypsin, alpha-chymotrypsin, poruoproteinase, coenzyme A, etc.), granules (tablets, capsules and the like, and common cold drugs, antiallergic drugs, phlegm-reducing and cough-relieving drugs, analgesics, digestive drugs, vitamins, antibiotics and the like) and liquid agents (glucose sodium chloride injection, concentrated sodium chloride injection, arginine injection, terbutaline sulfate for injection, levofloxacin lactate injection, ambroxol hydrochloride injection, potassium chloride injection, heparin sodium injection, glucose injection, dexamethasone sodium phosphate injection, adenosine triphosphate injection, cimetidine injection, fluconazole injection, tylan for injection, deazamycin for injection, vitamin c injection, vitamin B6 injection, furosemide injection and the like).

The injection bottle crusher 4 is used for directly crushing injection glass bottles. The injection type glass bottle is a small glass bottle (small-sized glass bottle) filled with powdered medicine or liquid medicine, is difficult to open manually, and can be directly crushed by an injection type bottle crusher 4. The glass bottle of injection class after smashing adopts the mode of artifical washing, washes away interior powder dress thing of bottle and liquid, collects the waste liquid that washs the acquisition, holds in third waste liquid bucket (not shown in the figure), and the waste liquid in the third waste liquid bucket is liquid danger useless promptly. And the third waste liquid barrel is conveyed to the liquid hazardous waste treatment subsystem through a forklift for harmless treatment. The cleaned and crushed glass bottles for injections are filled in a small glass bottle box (not shown), and then conveyed to a vertical warehouse for temporary storage through a forklift. The sorting platform 1 is used for manually sorting non-injection glass bottles (large-size glass bottles and extra-large-size glass bottles). The sorting deck 1 comprises a bottle washing basin 3 and work tables 2 located on both sides of the bottle washing basin 3. The two ends of the sorting table 1 are provided with a first glass collecting basket 5 and a second glass collecting basket 6 (generally called glass collecting baskets) and a first packing collecting basket 7 and a second packing collecting basket 8 (generally called packing collecting baskets), which are generally called collecting frames. As shown in fig. 1, two sides of each workbench 2 are respectively provided with a manual sorting position 9, and a worker stands on the manual sorting position 9 to manually screen the non-injection glass bottles, and the specific operations are as follows: the worker unscrews the caps of the glass bottles into the first packing collection basket 7 or the second packing collection basket 8, and also unlocks the packages of the glass bottles into the first packing collection basket 7 or the second packing collection basket 8; workers need to put the non-injection glass bottles into the bottle washing tank 3 for cleaning (a water tap which is commonly used in the prior art is arranged above the bottle washing tank 3), break the non-injection glass bottles, and put the broken non-injection glass bottles into the first glass collecting basket 5 or the second glass collecting basket 6. All be used for holding in little glass bottle case, first glass collect basket 5 or the second glass collect basket 6 and wait broken glass, all transport to the vertical warehouse through fork truck and keep in. The bottom intercommunication in wash-bottle pond 3 has the outlet pipe, and first waste liquid bucket (not shown in the figure) has been placed to the outlet pipe below, and first waste liquid bucket is used for connecing greatly from the wash-bottle pond 3 outflow water (be liquid danger useless). First waste liquid bucket transports to liquid danger waste disposal subsystem through fork truck and carries out innocent treatment.

The crushing equipment group is located in a factory building (crushing plant) with a height of three floors, as shown in fig. 2, a bin 11 is fixed on the ceiling of the third floor of the crushing plant through screws, and the bin 11 is arranged in the ceiling in a penetrating manner. An overturning machine 10 for feeding the storage bin 11 is arranged above the storage bin 11, and the overturning machine 10 is fixed on the roof through screws. The water is added into the bin 11 by the tipper 10 at the same time, so as to prevent some medicines from crystallizing (the bottles often contain chemical substances such as medicines, and the crystallization can block pipelines) in the crushing process. During the crushing operation, the material (from the vertical warehouse, the crushed injection glass bottles from the small glass bottle box, or the artificially crushed non-injection glass bottles from the first glass collecting basket 5 and/or the second glass collecting basket 6) is sent to the bin 11 by the turnover machine 10. The lower part of the storage bin 11 is communicated with a feed inlet of a vibrating feeder 13 (fixed on the ground of the third floor by screws) through a soft connection 12 (a soft pipeline), a discharge outlet of the vibrating feeder 13(XFZ) is communicated with a feed inlet of a first-stage crusher 14 (fixed on the ground of the third floor by screws), a discharge outlet of the first-stage crusher 14(PC, hammer crusher) is communicated with a feed inlet of a second-stage crusher 15 (fixed on the ground of the second floor by screws) through a pipeline (the pipeline penetrates through the ground of the third floor), a discharge outlet of the second-stage crusher 15(PFL, hammer crusher) is communicated with a feed inlet of a draining screw conveyor 16 (the draining screw conveyor 16 is fixed on a rack, and the rack is not shown in figure 2). The draining screw conveyor 16(WLS) comprises a conveying drum at an angle of 10 ° to the horizontal. The screw blade is arranged in the conveying cylinder of the draining screw conveyor 16, the screw blade drives the solid matter to be conveyed to the higher end of the conveying cylinder, and meanwhile, the liquid matter flows to the lower end of the conveying cylinder. The left end intercommunication of carrying the section of thick bamboo has the waste liquid pipe of vertical setting, and second waste liquid bucket 17 has been placed to the lower extreme of waste liquid pipe. The liquid that second waste liquid bucket 17 was collected is also that liquid danger is useless, will be carried to liquid danger by fork truck and useless the processing subsystem and carry out innocent treatment. The right end of the conveying cylinder is communicated with a vertically arranged discharge pipe, the discharge pipe is communicated with a vibrating screen classifier 18(XFZ), and the vibrating screen classifier 18 is also fixed on the frame. The vibrating screen machine 18 is provided with an oversize material outlet and an undersize material outlet, a first containing basket 19 (which can be placed on the frame) is placed under the undersize material outlet, a second containing basket 20 is placed under the oversize material outlet, the second containing basket 20 is placed on a platform scale 21(PFA220-ES3000), and the platform scale 21 is fixed on the ground of a floor. The first basket 19 is used for containing oversize materials such as bottle caps and the like, and the second basket 20 is used for containing undersize materials such as cullet and the like. Since the primary crusher 14 and the secondary crusher 15 are hammer crushers, glass can be effectively crushed, the bottle caps are usually made of rubber, plastic or metal, the hammer crushers are difficult to break the bottle caps, the particle size difference between the crushed glass and the bottle caps can be generated, and the crushed glass and the bottle caps can be separated by the vibrating screen 18 (the screen mesh of the vibrating screen is 8 mm). The particle size of cullet is below 8mm, and the diameter of the bottle cap is generally above 10mm, so that materials such as the bottle cap are oversize materials, and cullet is undersize materials. The cullet in the second containing basket 20 is transported to a vertical warehouse for temporary storage through a forklift, and the cullet is weighed and packaged to obtain a solid inorganic hazardous waste finished product (the particle size is less than or equal to 8mm, the water content is less than or equal to 5%, the impurity rate is less than or equal to 5%, and impurities refer to plastics, metal objects and the like) which can be used as a raw material for manufacturing cement in a cement plant. The materials in the first containing basket 19 are also conveyed to the vertical warehouse by the forklift for temporary storage, because the first containing basket 19 is used for containing oversize materials such as bottle caps, the oversize materials are mainly bottle caps, and the crushed glass (the crushed glass cannot be undersize materials) with larger particle sizes can be wrapped or attached, the materials in the first containing basket 19 need to be crushed again, so that the particle sizes of the dangerous waste glass meet the requirements, and then the materials are sieved to be undersize materials and are completely recycled and utilized. In the process of treating solid inorganic matter dangerous waste, a large amount of waste packages can be generated, and the solid organic matter dangerous waste can be conveyed to a solid organic matter dangerous waste treatment subsystem for treatment as the solid organic matter dangerous waste.

Second, liquid danger is useless to handle subsystem

The first screening unit A, the crushing unit B and the second screening unit D are sequentially arranged along the direction of material movement. And the nitrogen production unit C is used for conveying nitrogen to the crushing unit B. After the solid organic matter dangerous waste is recycled (from upstream enterprises and generated in the production process of the upstream enterprises), the solid organic matter dangerous waste is divided into crushing dangerous waste R1 to be screened and qualified dangerous waste R2 through physicochemical property detection. The hazardous waste of the solid organic matters is mainly light materials such as clothes, woven fabrics, cotton gloves, rubber gloves, PP/PE/HEPE/LDPE/PVC barrels, fiber filter cloth, packing materials and the like with various textures contaminated by a small amount of hazardous articles. The solid dangerous waste collected from waste production enterprises is often entrained with metal substances, and the mixed loading phenomenon is common. Common hazardous substances infected by solid organic hazardous wastes mainly comprise mineral oil, a solvent, a dye, a coating, paint, inorganic acid and the like. The hazardous waste of the solid organic matters is mainly HW06, HW12, HW49 and the like in the national records of hazardous waste, and has flammability (the possibility of spontaneous combustion exists a little) and certain volatility. In addition, the judgment standard of qualified dangerous waste R2 is two: (1) all are solid organic matters; (2) the grain diameter is less than 150 mm. The solid organic matter dangerous wastes which do not meet the standard of the qualified dangerous wastes R2 are classified into crushing dangerous wastes R1 to be screened. The qualified hazardous waste R2 can be directly compressed and boxed to obtain a solid organic matter hazardous waste finished product F; and the dangerous waste R1 to be screened and crushed needs to be screened and crushed to obtain the solid organic matter dangerous waste finished product F. The equipment setting conditions of the harmless treatment of the hazardous waste R1 to be screened and crushed are as follows:

the first sieving unit a includes a manual sorting station (not shown), a first belt conveyor a1, a second belt conveyor a2, a first magnetic separator A3(RCYD), and a metal detector a4 (IMD-I). The second belt conveyor a2 is located at the end of the first belt conveyor a1, and the second belt conveyor a2 is at a lower elevation than the first belt conveyor a 1. The first magnetic separator A3 and the metal detector a4 are both fixed above the first belt conveyor a1 (the first magnetic separator A3 and the metal detector a4 are both fixed through a rack), and the manual sorting positions are arranged on both sides of the first belt conveyor a 1. The manual separation position, the first magnetic separator A3 and the metal detector a4 are arranged in sequence along the direction in which the material is conveyed on the first belt conveyor a1 (the direction of movement of the material). After the materials (to-be-screened and crushed hazardous waste R1) are sorted on the first belt conveyor A1, the materials become screened solid organic matter hazardous waste, and then the screened solid organic matter hazardous waste is conveyed to the second belt conveyor A2 to be conveyed continuously.

The crushing unit B comprises a material pit B1 and a crusher B3 which are arranged in sequence along the direction of movement of the material. The second belt conveyor A2 conveys materials (namely the screened solid organic matter danger) to a material pit B1 for temporary storage, a grab bucket crane B2 grabs the materials in the material pit B1 and puts the materials into a crusher B3(Q100HD, SSI, shear type crusher), and a crusher B3 completes crushing treatment on the screened solid organic matter danger waste to obtain crushed materials. In order to increase the safety of the crusher unit B and prevent the combustion and explosion of the material in the crusher B3, the present embodiment modifies the crusher B3. The structure of the crusher B3 of the prior art is as follows: the crusher B3 comprises a crushing chamber 45, an upper gate is arranged at the upper opening of the crushing chamber 45, a lower gate is arranged at the lower opening of the crushing chamber 45, and a double-shaft tearing type cutter set is arranged in the crushing chamber 45. In this embodiment, a through hole is formed in the side wall of the crushing chamber 45, the through hole is communicated with a dredging pipe 47, the dredging pipe 47 is welded to the side wall of the crushing chamber 45, and the dredging pipe 47 is located above the biaxial tearing type cutter set (compared with the situation that the dredging pipe 47 is located below the biaxial tearing type cutter set, the material is prevented from entering the dredging pipe 47). As shown in fig. 10 and 11, a fixed flange 48 is integrally formed at an end of the conducting pipe 47 remote from the crushing chamber 45, a detachable flange 49 is fixed to the fixed flange 48 by a bolt and nut structure, and the fixed flange 48 and the detachable flange 49 press the safety rupture disk 50 against the conducting pipe 47. The detachable flange 49 is formed by integrally forming a short pipe and a disk surface in the middle, the short pipe is coaxial with the disk surface, and the inner diameter and the outer diameter of the short pipe are consistent with those of the dredging pipe 47. In this embodiment, the safety rupture disk 50 is a rubber disk, and the surface of the safety rupture disk 50 is provided with non-penetrating scratches. One end of the intrinsically safe rupture membrane 50 of the evacuation conduit 47 needs to be directed to an open place, and cannot be set up against a person or an object such as equipment, so as to prevent the eruption during the rupture from injuring the person or damaging the equipment.

As shown in fig. 10, the lower portion of the crushing chamber 45 communicates with a nitrogen generation system (not shown in fig. 2) of the nitrogen generation unit C through a nitrogen gas delivery pipe 46. When the material is crushed, the oxygen content in the crushing chamber 45 needs to be kept less than 8%, and the oxygen content in the crushing chamber 45 is adjusted in a mode of flushing nitrogen. When the crusher B3 is used for crushing the screened waste solid organic matter, the upper gate is opened, the waste solid organic matter danger is added into the crushing chamber 45, then the upper gate is closed, nitrogen is flushed into the crushing chamber 45, and the oxygen content in the crushing chamber 45 is adjusted to be less than 8% (in the process, the upper gate and the lower gate seal the crushing chamber 45, the pressure in the crushing chamber 45 is continuously increased by the filled nitrogen, and the oxygen content is compressed to be less than 8%). After the crushing operation is finished, the lower gate is opened to discharge. Each crushing operation requires readjustment of the pressure in the crushing chamber 45 to below 8%. Preferably, a nitrogen tank is further provided between the nitrogen producing unit C and the crushing chamber 45 for temporarily storing nitrogen gas, because the crusher B3 cannot be operated continuously and the next crushing operation can be performed only after one crushing operation is completed. In addition, the crushing unit B is provided with an alarm device (TW07-P series main unit, temperature sensor equipped with PT100 model), the temperature sensor of which is installed in the crushing chamber 45 for detecting the temperature in the crushing chamber 45. When the temperature in the crushing chamber 45 is higher than 80 ℃, the alarm device gives an alarm to prompt an operator (first high-temperature alarm), the material in the crusher B3 is in danger of explosion or combustion, and the operator determines whether to stop feeding or stop crushing operation when the crusher is shut down according to the field condition; when the temperature in the crushing chamber 45 is higher than 100 ℃, the alarm device gives an alarm to prompt the operator again (second high temperature alarm), and at the moment, the machine must be shut down to stop feeding and crushing operation.

The second screening unit D includes a third belt conveyor D1 and a second magnetic separator D2(RCYD), the second magnetic separator D2 being fixed above the third belt conveyor D1 (the second magnetic separator D2 being fixed by a frame). The crushed material output from the crusher B3 was subjected to screening by the second magnetic separator D2 while being conveyed by the third belt conveyor D1 to remove metal particles, and the screened crushed material was obtained. And compressing the screened crushed material by a compressor P to obtain a solid organic hazardous waste finished product F. The compression treatment is to make the product regular in shape and easy to pack.

The processing route of the solid organic waste danger is as follows:

(1) step of preliminary classification

After the solid organic matter dangerous waste is recovered, physical and chemical property detection is carried out, the solid organic matter dangerous waste which meets the process requirements (such as particle size, type and the like) is divided into qualified dangerous waste R2, the qualified dangerous waste R2 is transmitted to a compressor P through a transmission unit E (comprising a fourth belt conveyor E1), and a solid organic matter dangerous waste finished product F is formed after compression treatment. And the solid organic matter dangerous waste with the physicochemical property detection result not meeting the process requirement is divided into crushing dangerous waste R1 to be screened. The range of the solid organic matter hazardous waste is shown in table 1, wherein the category refers to the category specified in the national hazardous waste record.

TABLE 1 solid organics hazardous waste Range

(2) First sieving step

This step is carried out in the first screening unit a. The hazardous waste R1 to be screened and crushed is conveyed into a first belt conveyor A1, and after being manually sorted (inorganic substances or flammable and explosive substances such as metal substances, glass, batteries and lighters are removed, and large objects which cannot enter a crusher B3 are removed) and metal substances (mainly iron) are removed by a first magnetic separator A3, a metal detector A4 detects whether metal substances exist in the materials. If the metal detector A4 shows that no metal substance exists in the material, qualified solid organic waste danger after screening is obtained. If there is metal material in the metal detector A4 material, it is necessary to stop the machine (stop the first belt conveyor A1) and retrieve the material on the first belt conveyor A1 and re-screen it (re-manual screening and first magnetic separator A3 screening). The screened waste solid organic matter danger is conveyed to a second belt conveyor A2 from a first belt conveyor A1, and then conveyed to a material pit B1 in a crushing unit B by a second belt conveyor A2 for temporary storage.

(3) A crushing step

This step is carried out in the crushing unit B. Since the crusher B3 cannot work continuously, a pit B1 is required to temporarily store the material. The belt speed (1.5m/s-2m/s) of the second belt conveyor A2 is higher than that (2-10m/min) of the first belt conveyor A1, so that the materials can be quickly thrown into a pit (a material pit B1), the situation that the materials are attached to the wall of the material pit B1 due to slow falling to affect the operation of stacking and a grab bucket B2 is avoided, and the loss of equipment is reduced. While the first belt conveyor a1 is slower in speed, enough time may be reserved for various screening operations. And the screened solid organic matter dangerous waste in the material pit B1 is grabbed into a crusher B3 by a grab bucket B2, and crushed materials are obtained after crushing treatment.

(4) Second sieving step

This step is carried out in the second screening unit D. The crushed materials are conveyed by a third belt conveyor D1, and simultaneously the metal particle removing operation is carried out on the crushed materials by a second magnetic separator D2, so that the sieved crushed materials are obtained.

(5) Step of obtaining finished product

And (3) compressing the screened crushed material by a compressor P to obtain a solid organic hazardous waste finished product F (the physical and chemical indexes are shown in Table 2). The particle size of the solid organic matter dangerous waste finished product F is smaller than or equal to 150mm, the solid organic matter dangerous waste finished product F with the particle size is a more economical and efficient choice, can be used as a fuel, and the production cost is controlled in a reasonable range.

Example 3

This embodiment is basically the same as embodiment 1, except that, as shown in fig. 12, a cleaning structure is further provided in the leading pipe 47 of this embodiment, and the fixing manner of the safety rupture disk 50 is different. Because when the material explodes in the crushing chamber 45, part of crushed aggregates can be rushed into the dredging pipe 47, and as long as time passes, the dredging pipe 47 can be blocked, so that the explosion-proof effect is influenced (gas can not be removed in time), the structure is optimized by the embodiment, and the situation is avoided. In this embodiment, the safety rupture disk 50 is no longer fixed to the guide pipe 47 by means of a flange, but is crimped to the end of the guide pipe 47 remote from the crushing chamber 45 by means of a pipe cover 51. The outer side of the cylindrical side wall of the pipe cover 51 is provided with an internal thread, and the outer side of the pipe wall of the dredging pipe 47 is provided with an external thread matched with the internal thread.

In use, the safety rupture disk 50 is now fixed to the tube cap 51 by the connecting rod 52, the cleaning ring 53 is then placed into the guide tube 47, and finally the tube cap 51 is screwed. If a burst occurs, the safety rupture disk 50 is ruptured, requiring replacement of the safety rupture disk 50. In the process of taking out the pipe cover 51, the pipe cover 51 moves towards the direction far away from the crushing chamber 45, meanwhile, the cleaning ring 53 is driven to move, the cleaning ring 53 and the spiral metal wire 54 have a cleaning effect on the inner wall of the dredging pipe 47, and the accumulation of particle substances is avoided. In addition, when the pipe cover 51 is taken out, the pipe cover 51 needs to be rotated first, and the connecting rod 52 drives the cleaning ring 53 to rotate in the dredging pipe 47, so that the inner wall of the dredging pipe 47 can be rubbed and cleaned more thoroughly.

The present embodiment is different from embodiment 1 in that: in this embodiment, as shown in fig. 16, since the liquid waste in the liquid waste treatment subsystem in the present technical solution is transported by using the pipeline 73 (liquid transportation among the raw material tank 22, the reaction kettle 23, and the finished product tank 24), in order to avoid the problem of blockage of the pipeline 73, the connection mode of the pipeline 73 and the structure of the connection member are improved.

In this embodiment, as shown in fig. 17 and 18, the pipes 73 are divided into two parts and connected to each other by a regulating valve, the regulating valve includes a fixing part and a regulating part, the fixing part in this embodiment is a fixing ring 74 which can be connected to the pipes 73, and an opening and closing valve for opening and closing an inner hole of the fixing ring 74 is disposed on an inner diameter of the fixing ring 74. An adjusting ring 75 (adjusting part) is rotatably connected to the fixing ring 74, the inner diameter of the adjusting ring 75 is smaller than that of the fixing ring 74, flushing holes 76 are axially and uniformly distributed in the adjusting ring 75, the flushing holes 76 are attached to the inner wall of the pipeline 73 to be connected, and in order to ensure the flushing effect, the flushing holes 76 can be set to be inclined towards the inner wall of the pipeline 73 so as to regulate the flushing direction. The circumference equipartition rigid coupling has a plurality of supporting seats 77 on the adjustable ring 75, and the equal rigid coupling has the telescopic link 78 of L shape on the supporting seat 77, and telescopic link 78 is electric telescopic handle 78, can realize its is flexible through the electric control. As shown in fig. 19, a cleaning block 79 attached to the inner wall of the pipe 73 to be connected is fixed to one end of the telescopic rod 78 away from the support base 77, and one end of the cleaning block 79 attached to the inner wall of the pipe 73 is formed in an arc shape.

When liquid danger is useless and flows in pipeline 73, the ooff valve is in the state of opening, and liquid danger is useless can follow a pipeline 73, in fixed ring 74, adjustable ring 75 and finally flow to next section pipeline 73 in proper order, realizes the useless transport of liquid danger, and most liquid danger is useless can be from the hole circulation of fixed ring 74 and adjustable ring 75's internal diameter this moment, and the flow is great. When the pipe 73 is used for a period of time and a blockage problem occurs, an operator can judge which pipe 73 has the blockage problem according to experience or knocking the pipe 73, and then close the on-off valve at the input end of the pipe 73. After that, the dissolving agent or the cleaning water is poured into the pipe 73, the cleaning water rapidly flows into the fixing ring 74 at a certain flow rate, and the cleaning water flows out only from the flushing hole 76 due to the closing of the on-off valve, and the water pressure increases and the cleaning water is ejected from the flushing hole 76 due to the large water flow of the inflow water and the small diameter of the flushing hole 76 at a certain flow rate. Since the washing holes 76 are inclined toward the inner wall of the duct 73, the washing water collides against the inner wall of the duct 73 to dilute and wash away the dirt on the inside of the duct 73. And at the same time, the telescopic rod 78 is controlled to extend, so that the cleaning block 79 moves close to the inner wall of the pipeline 73 to scrape off the dirt on the inner wall of the pipeline 73. Because the adjustable ring 75 is connected on fixed ring 74 for rotating, when wasing water impact adjustable ring 75, adjustable ring 75 can produce the rotation of certain degree, can realize that the multi-angle of pipeline 73 inner wall, diversified wash with the dirt strikes off, avoid producing the dead angle.

This embodiment can realize the fixed point clearance to specific pipeline 73 through the synergism that washes, dilutes and strike off, and need not dismantle whole pipeline 73 get off, and the construction degree of difficulty is little, convenient operation, and the precision is high.

The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail.
