DETAILED DESCRIPTION

[0058] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0059] Reference Figure 1 , shows a schematic diagram of the structure of a hazardous waste dumping and filtering system provided in an embodiment of the present invention, which may specifically include the following steps:

[0060] The embodiment of the present invention discloses a hazardous waste dumping and filtering system, which includes: a hazardous waste barrel conveyor belt 1, a hazardous waste barrel treatment box 2 connected to the hazardous waste barrel conveyor belt 1, a hazardous waste filter screen arranged at the bottom of the hazardous waste barrel treatment box 2, a barbed steel plate 5 arranged at the top of the hazardous waste barrel treatment box 2, and a hazardous waste storage tank 9 arranged below the hazardous waste filter screen.

[0061] The hazardous waste barrel conveyor belt 1 is used to transport the hazardous waste barrels to the hazardous waste barrel treatment box 2;

[0062] The barbed steel plate 5 is used to lower the barbed steel plate 5 to pierce the hazardous waste barrel, so that the hazardous waste liquid in the hazardous waste barrel flows out; the hazardous waste liquid contains solid impurities of different particle sizes;

[0063] Reference Figure 2 , showing a schematic diagram of the structure of a hazardous waste filter provided in an embodiment of the present invention. The hazardous waste filter comprises a fixed filter 7 and a mobile filter 8 disposed on the upper side or the lower side of the fixed filter 7. The hazardous waste filter is used to adjust the position of the mobile filter 8 relative to the fixed filter 7 to adjust the impurity particle size allowed to pass through the hazardous waste filter, so that the hazardous waste liquid and the solid impurities in the hazardous waste liquid that meet the impurity particle size allowed to pass flow into the hazardous waste storage tank 9;

[0064] The hazardous waste storage tank 9 is used to add an emulsifier to form a stable mixture of the hazardous waste liquid.

[0065] Specifically, in the embodiment of the present invention, the hazardous waste barrel conveyor belt 1 can be intermittently operated to convey a preset number of hazardous waste barrels to the hazardous waste barrel treatment box 2. The hazardous waste barrel treatment box 2 can be a space for accommodating hazardous waste barrels, which can be provided with a first openable baffle 3. The first openable baffle 3 can be opened to allow the hazardous waste barrels conveyed by the hazardous waste barrel conveyor belt 1 to be input into the hazardous waste barrel treatment box 2.

[0066] The hazardous waste barrel can be a container containing hazardous waste liquid, which can usually be made of plastic. The capacity of the container can be determined according to actual needs, such as 100ml, 500ml, 1L, 5L, 10L, 50L, etc., and the present invention does not limit this.

[0067] The number of hazardous waste barrels conveyed by the hazardous waste barrel conveyor belt 1 can be determined based on the amount of hazardous waste liquid that can be contained in the hazardous waste storage tank 9 and the capacity of the hazardous waste barrel. Generally speaking, the number of hazardous waste barrels conveyed by the hazardous waste barrel conveyor belt 1 can be the amount of hazardous waste liquid that can be contained in the hazardous waste storage tank 9 / the capacity of the hazardous waste barrel.

[0068] The hazardous waste storage tank 9 may have a maximum amount of hazardous waste liquid that can be accommodated. Generally speaking, the amount of hazardous waste liquid that the hazardous waste storage tank 9 can hold can be set equal to the maximum amount of hazardous waste liquid that can be accommodated. If it is necessary to pre-treat the hazardous waste liquid to a certain extent in the hazardous waste storage tank 9, the amount of hazardous waste liquid that the hazardous waste storage tank 9 can hold is lower than the maximum amount of hazardous waste liquid that can be accommodated. The amount of hazardous waste liquid that the hazardous waste storage tank 9 can hold can be set to 2 / 3, 1 / 2, 1 / 3, etc. of the maximum amount of hazardous waste liquid that can be accommodated, and the present invention does not limit this.

[0069] A barbed steel plate 5 can be provided on the top of the hazardous waste barrel treatment box 2, and the barbed steel plate 5 can move up and down. Therefore, after the hazardous waste barrel conveyor belt 1 transports the hazardous waste barrel to the hazardous waste barrel treatment box 2, the barbed steel plate 5 can be lowered to pierce the hazardous waste barrel, so that the hazardous waste liquid in the hazardous waste barrel can flow out.

[0070] In an embodiment of the present invention, the hazardous waste liquid may be a liquid containing components such as organic acids and alkalis, inorganic acids and alkalis, heavy metals, etc. In addition to the liquid, the hazardous waste liquid may also contain solid impurities of different particle sizes. The solid impurities may have a certain adverse effect on the treatment of the hazardous waste liquid. Therefore, the larger solid impurities in the hazardous waste liquid can be separated during the dumping process of the hazardous waste barrel.

[0071] Thus, a hazardous waste filter can be set at the bottom of the hazardous waste barrel treatment box 2. The hazardous waste filter can include a fixed filter 7 and a movable filter 8. The fixed filter 7 and the movable filter 8 can be respectively composed of a plurality of steel bars, and there are gaps between the steel bars. Thus, by moving the movable filter 8 left and right, the relative position between the steel bars of the movable filter 8 and the steel bars of the fixed filter 7 can be changed, so that the gap between the steel bars of the fixed filter 7 and the steel bars of the fixed filter 7 can be adjusted, so that the particle size of solid impurities allowed to pass through the hazardous waste filter can be adjusted.

[0072] In the embodiment of the present invention, in order to improve the treatment efficiency of hazardous waste dumping and filtration, solid impurities of a certain particle size can be allowed to pass through the hazardous waste filter. The particle size of the impurities allowed to pass can be determined according to actual needs, such as 5mm, 3mm, 2mm, etc., and the present invention does not limit this.

[0073] After the barbed steel plate 5 pierces the hazardous waste barrel, allowing the hazardous waste liquid to flow into the hazardous waste storage tank 9 , the hazardous waste liquid can be further processed in the hazardous waste storage tank 9 .

[0074] Generally speaking, hazardous waste liquids may contain a variety of different chemical substances, and these chemical substances may have density differences or incompatibilities, which may make the hazardous waste liquids easily stratified, affecting the effect of subsequent treatment of the hazardous waste liquids. Therefore, an emulsifier may be added to the hazardous waste storage tank 9 to form a stable mixture of the hazardous waste liquids, so that in the subsequent treatment process, the hazardous waste contained therein will not be insufficiently treated due to the stratification of the hazardous waste liquids.

[0075] In an embodiment of the present invention, the hazardous waste dumping and filtering system provided by the present invention can realize the automated processing of hazardous waste barrels without the need for manual processing of hazardous waste barrels. Specifically, the hazardous waste barrel can be first placed on the hazardous waste barrel conveyor belt 1, and transported to the hazardous waste barrel treatment box 2 by the hazardous waste barrel conveyor belt 1. The barbed steel plate 5 on the top of the hazardous waste barrel treatment box 2 descends, pierces the hazardous waste barrel, and causes the hazardous waste liquid in the hazardous waste barrel to flow out. The left and right movement of the mobile filter 8 can be controlled to realize automatic control of the particle size of impurities allowed to pass through the hazardous waste filter at the bottom of the hazardous waste barrel treatment box 2. The hazardous waste liquid and some solid impurities contained in the hazardous waste liquid can flow into the hazardous waste storage tank 9 through the hazardous waste filter. The hazardous waste storage tank 9 can be provided with an inlet for additives and a stirring paddle, and an emulsifier can be added to the hazardous waste storage tank 9 through the inlet for additives, and the hazardous waste liquid can be stirred by the stirring paddle to form a stable mixture of the hazardous waste liquid, thereby realizing the collection and pretreatment of the hazardous waste liquid.

[0076] The hazardous waste dumping and filtering system provided by the embodiment of the present invention comprises: a hazardous waste barrel conveyor belt, a hazardous waste barrel treatment box connected to the hazardous waste barrel conveyor belt, a hazardous waste filter screen arranged at the bottom of the hazardous waste barrel treatment box, a barbed steel plate arranged at the top of the hazardous waste barrel treatment box, and a hazardous waste storage tank arranged below the hazardous waste filter screen; wherein the hazardous waste filter screen comprises a fixed filter screen and a movable filter screen arranged at the upper side or the lower side of the fixed filter screen; the hazardous waste barrel conveyor belt is used to transfer the hazardous waste barrel to the hazardous waste barrel treatment box; the belt The barbed steel plate is used to lower the barbed steel plate to pierce the hazardous waste barrel, so that the hazardous waste liquid in the hazardous waste barrel flows out; the hazardous waste liquid contains solid impurities of different particle sizes; the hazardous waste filter is used to adjust the position of the mobile filter relative to the fixed filter to adjust the impurity particle size allowed to pass through the hazardous waste filter, so that the hazardous waste liquid and the solid impurities in the hazardous waste liquid that meet the impurity particle size allowed to pass flow into the hazardous waste storage tank; the hazardous waste storage tank is used to add an emulsifier to form a stable mixture of the hazardous waste liquid. As a result, the hazardous waste dumping and filtering system can be used to process the hazardous waste liquid without the need for an operator, thereby improving the processing efficiency and realizing the automatic recovery of the hazardous waste liquid. In addition, the pretreatment of the hazardous waste liquid can be completed simultaneously, which is convenient for the subsequent further processing of the hazardous waste liquid.

[0077] In one embodiment of the present invention, Figure 3 Schematic diagram of the structure of a barbed steel plate and a perforated steel plate provided in an embodiment of the present invention. A perforated steel plate 6 matching the barbed steel plate 5 is also provided on the top of the hazardous waste barrel treatment box 2; the barbed steel plate 5 is provided with a plurality of steel barbs, and the perforated steel plate 6 is provided with a plurality of holes matching the steel barbs;

[0078] The barbed steel plate 5 is specifically used to lower the barbed steel plate 5 , and the steel spikes on the barbed steel plate 5 pierce the hazardous waste barrel through the holes on the perforated steel plate 6 , so that the hazardous waste liquid in the hazardous waste barrel flows out.

[0079] Specifically, a perforated steel plate 6 matching the barbed steel plate 5 is also provided on the top of the hazardous waste barrel treatment box 2, and a plurality of steel barbs are provided on the barbed steel plate 5, and a plurality of holes matching the steel barbs are provided on the perforated steel plate 6, so that the barbed steel plate 5 can pass through the perforated steel plate 6 and reduce the risk of piercing the hazardous waste barrel in the hazardous waste barrel treatment box 2.

[0080] After the hazardous waste barrel is pierced, the barbed steel plate 5 can be separated from the hazardous waste barrel, so that the hazardous waste liquid in the hazardous waste barrel can flow out smoothly. Therefore, by providing the perforated steel plate 6, during the process of the barbed steel plate 5 rising and retracting, the perforated steel plate 6 can resist the hazardous waste barrel, so that the hazardous waste barrel cannot continue to rise with the barbed steel plate 5, thereby separating the steel spikes on the barbed steel plate 5 from the hazardous waste barrel. At the same time, after the barbed steel plate 5 is retracted, the perforated steel plate 6 can protect the operator to a certain extent and avoid direct contact with the barbed steel plate 5.

[0081] Optionally, the perforated steel plate 6 can also move up and down. During the process of the barbed steel plate 5 descending to pierce the hazardous waste barrel, the perforated steel plate 6 can also descend synchronously, so that the hazardous waste barrel can be pressed and fixed by the perforated steel plate 6, thereby preventing the steel barbs from being unable to pierce the hazardous waste barrel normally due to the rolling of the hazardous waste barrel.

[0082] In one embodiment of the present invention, the system further comprises a delivery pump 10 connected to the hazardous waste storage tank 9;

[0083] The delivery pump 10 is used to deliver the hazardous waste liquid in the hazardous waste storage tank 9 to the outside of the hazardous waste dumping and filtering system, or to deliver the hazardous waste liquid in the hazardous waste storage tank 9 to the hazardous waste barrel treatment box 2 .

[0084] Specifically, the system may be provided with a delivery pump 10 connected to the hazardous waste storage tank 9. A first valve 12 may be provided between the delivery pump 10 and the hazardous waste storage tank 9. When the hazardous waste liquid is dumped, the first valve 12 may remain closed. After the hazardous waste liquid is dumped to a certain extent or the dumping and pretreatment are completed, the first valve 12 may be opened to allow the hazardous waste liquid to flow to the delivery pump 10.

[0085] The delivery pump 10 can be connected to two delivery channels, one delivery channel can be used to deliver the hazardous waste liquid in the hazardous waste storage tank 9 to the outside of the hazardous waste dumping and filtering system, and the other delivery channel can be used to re-deliver the hazardous waste liquid in the hazardous waste storage tank 9 to the hazardous waste barrel treatment box 2 for re-filtration treatment.

[0086] Among them, a second valve 13 can be set on the conveying channel for conveying the hazardous waste liquid in the hazardous waste storage tank 9 to the outside of the hazardous waste dumping and filtering system, and a third valve 14 can be set on the conveying channel for re-conveying the hazardous waste liquid in the hazardous waste storage tank 9 to the hazardous waste barrel treatment box 2. The second valve 13 or the third valve 14 can be opened to complete the conveyance of the hazardous waste liquid through the designated conveying channel by the conveying pump 10.

[0087] In one embodiment of the present invention, the system further comprises a filter 11 disposed between the hazardous waste storage tank 9 and the delivery pump 10;

[0088] The filter 11 is used to filter solid impurities in the hazardous waste liquid in the hazardous waste storage tank 9 .

[0089] Specifically, the filter 11 can generally be a stainless steel filter 11 , which can filter larger solid impurities in the hazardous waste liquid in the hazardous waste storage tank 9 to a certain extent, thereby preventing excessive solid impurities from affecting the normal operation of the delivery pump 10 .

[0090] In one embodiment of the present invention, the hazardous waste filter is specifically used to adjust the position of the mobile filter 8 relative to the fixed filter 7 when the hazardous waste liquid in the hazardous waste storage tank 9 is transported to the hazardous waste barrel treatment box 2, so as to reduce the particle size of impurities allowed to pass through the hazardous waste filter.

[0091] Specifically, in order to maintain a high hazardous waste liquid treatment efficiency and to fully clean the impurities that may exist in the hazardous waste liquid as much as possible, the hazardous waste liquid after the dumping and filtering treatment can be transported to the hazardous waste barrel treatment box 2 for filtering treatment again. When the hazardous waste liquid is transported to the hazardous waste barrel treatment box 2 for filtering treatment again, the hazardous waste filter screen can reduce the particle size of impurities allowed to pass through the hazardous waste filter screen by adjusting the position of the mobile filter screen 8 relative to the fixed filter screen 7, so that the particle size of solid impurities contained in the hazardous waste liquid can be further reduced.

[0092] In a specific implementation, if it is necessary to repeatedly dump the filtered hazardous waste liquid and then transport it to the hazardous waste barrel treatment box 2 for filtering, the particle size of impurities allowed to pass through the hazardous waste filter can be gradually reduced until the target impurity particle size is reached. Thus, the solid impurities in the hazardous waste liquid can be more fully removed by repeatedly dumping the filtered hazardous waste liquid.

[0093] Generally speaking, the particle size of impurities initially allowed to pass through the hazardous waste filter can be 5mm, and the particle size of impurities finally allowed to pass through can be 2mm. For example, in the case where it is necessary to repeat twice that the hazardous waste liquid after the dumping and filtering treatment can be transported to the hazardous waste barrel treatment box 2 for filtering treatment again. When the hazardous waste barrel is pierced for the first time to dump the hazardous waste liquid, the particle size of impurities allowed to pass through the hazardous waste filter can be 5mm. Thereafter, the hazardous waste liquid after the dumping and filtering treatment can be transported to the hazardous waste barrel treatment box 2 for filtering treatment again, and the particle size of impurities allowed to pass through the hazardous waste filter can be 3mm. Finally, when the hazardous waste liquid after the dumping and filtering treatment is repeated again, it can be transported to the hazardous waste barrel treatment box 2 for filtering treatment again, and the particle size of impurities allowed to pass through the hazardous waste filter can be 2mm.

[0094] In one embodiment of the present invention, the system further comprises a hazardous waste barrel collection box 15 , and the hazardous waste barrel collection box 15 is used to collect hazardous waste barrels and solid impurities discharged from the hazardous waste barrel treatment box 2 .

[0095] Specifically, the system may further include a hazardous waste barrel collection box 15. The hazardous waste barrel collection box 15 may be used to collect the hazardous waste barrel and solid impurities blocked by the hazardous waste filter, so that the solid impurities can be separated from the hazardous waste liquid as much as possible during the hazardous waste treatment process.

[0096] Optionally, the hazardous waste barrel treatment box 2 can be provided with a second openable baffle 4 on the side close to the hazardous waste barrel collection box 15. After the hazardous waste barrel in the hazardous waste barrel treatment box 2 is processed, the second openable baffle 4 can be opened, and the hazardous waste barrel and solid impurities blocked by the hazardous waste filter can be discharged from the outlet after the second openable baffle 4 is opened.

[0097] In one embodiment of the present invention, the system also includes a movable push plate 17 arranged on one side of the hazardous waste barrel treatment box 2; the movable push plate 17 is used to push the hazardous waste barrel in the hazardous waste barrel treatment box 2 into the hazardous waste barrel collection box by extending into the hazardous waste barrel treatment box 2 after the hazardous waste liquid in the hazardous waste barrel is dumped.

[0098] Specifically, in order to realize the automated processing of hazardous waste barrels by the hazardous waste dumping and filtering system of the present application, a movable push plate 17 can be further provided on one side of the hazardous waste barrel processing box 2. After the hazardous waste liquid in the hazardous waste barrel is dumped, the first openable baffle 3 and the second openable baffle 4 can be opened, so that the movable push plate 17 can extend from the opening on one side of the first openable baffle 3 into the hazardous waste barrel processing box 2, push the hazardous waste barrel in the hazardous waste barrel processing box 2, and push the hazardous waste barrel from the opening on one side of the second openable baffle 4 into the hazardous waste barrel collection box 15.

[0099] Optionally, in the process of pushing the hazardous waste barrel into the hazardous waste barrel treatment box 2, the hazardous waste barrel can roll to a certain extent under the thrust, and the position of the opening of the hazardous waste barrel can change, so that the hazardous waste liquid that may not be completely dumped out of the hazardous waste barrel can flow out due to the change in the opening position, so that the hazardous waste liquid in the hazardous waste barrel can flow out as much as possible. In this way, the moving speed of the movable push plate 17 in the process of pushing the hazardous waste barrel can be controlled, so that the opening of the hazardous waste barrel after being pierced can be maintained at different positions for a certain length of time during the pushing process, so that the hazardous waste liquid in the hazardous waste barrel can flow out as much as possible before being pushed into the hazardous waste barrel collection box 15.

[0100] In one embodiment of the present invention, the system further comprises a waste gas recovery device 16 disposed on the top of the hazardous waste barrel treatment box 2, and the waste gas recovery device 16 is used to recover the waste gas generated during the treatment of the hazardous waste barrel.

[0101] Specifically, during the hazardous waste treatment process, some chemical substances contained in the hazardous waste liquid may generate waste gas to a certain extent due to chemical reactions between each other, changes in the physical environment such as temperature and pressure, etc. Therefore, the system may also include a waste gas recovery device 16 disposed on the top of the hazardous waste barrel treatment box 2. The waste gas recovery device 16 can recover the waste gas generated during the hazardous waste barrel treatment process.

[0102] Optionally, in order to avoid pollution caused by exhaust gas, activated carbon can be set in the recovery process to absorb as much hazardous substances as possible in the exhaust gas.

[0103] In one embodiment of the present invention, the hazardous waste storage tank 9 is specifically used to reduce the viscosity of the hazardous waste liquid by adding a solvent.

[0104] Specifically, some hazardous waste liquids may have a higher viscosity, which may result in the inability to be normally transported by the delivery pump 10 due to excessive viscosity, and it may also be difficult to further process. Therefore, after the hazardous waste liquid enters the hazardous waste storage tank 9, the viscosity of the hazardous waste liquid can be reduced by adding solvents such as water, ethanol, etc.

[0105] As a specific example of the present invention, the treatment of hazardous waste barrels by the hazardous waste dumping and filtering system can be mainly achieved in the following ways:

[0106] The first openable baffle 3 is automatically opened, and the hazardous waste barrel is placed on the hazardous waste barrel conveyor belt 1, and is transported to the hazardous waste barrel treatment box 2 by the hazardous waste barrel conveyor belt 1. Thereafter, the first openable baffle 3 is automatically closed, and the barbed steel plate 5 on the top of the hazardous waste barrel treatment box 2 can automatically drop, pass through the perforated steel plate 6, pierce the hazardous waste barrel, and make the hazardous waste liquid in the hazardous waste barrel flow out.

[0107] The left and right movement of the mobile filter 8 can be controlled to realize automatic control of the impurity particle size allowed to pass through the hazardous waste filter at the bottom of the hazardous waste barrel treatment box 2. Initially, the impurity particle size allowed to pass through the hazardous waste filter can be set to 5mm to improve the dumping and filtering efficiency of hazardous waste liquid.

[0108] The hazardous waste liquid and some solid impurities contained in the hazardous waste liquid can flow into the hazardous waste storage tank 9 through the hazardous waste filter. The hazardous waste storage tank 9 can be provided with an additive inlet and a stirring paddle, and an emulsifier can be added to the hazardous waste storage tank 9 through the additive inlet, and the hazardous waste liquid can be stirred by the stirring paddle to form a stable mixture, thereby realizing the collection and pretreatment of the hazardous waste liquid. At the same time, if the hazardous waste liquid has a high viscosity, a solvent can be further added through the additive inlet to reduce the viscosity of the hazardous waste liquid.

[0109] After the hazardous waste liquid is dumped, the barbed steel plate 5 can automatically rise, so that the steel spikes are retracted to a position above the perforated steel plate 6. If the hazardous waste barrel is not separated from the steel spikes on the barbed steel plate 5 during the rising process of the barbed steel plate 5, the perforated steel plate 6 can be used to support the hazardous waste barrel, preventing the hazardous waste barrel from continuing to rise with the barbed steel plate 5, so that the hazardous waste barrel is not separated from the barbed steel plate 5.

[0110] Thereafter, the first openable baffle 3 and the second openable baffle 4 can be opened, and the movable push plate 17 can extend into the hazardous waste barrel treatment box 2 through the opening of the first openable baffle 3, and push the hazardous waste barrel into the hazardous waste barrel collection box 15 from the opening of the second openable baffle 4. In the process of pushing the hazardous waste barrel into the hazardous waste barrel treatment box 2, the hazardous waste barrel can roll to a certain extent under the thrust, and the position of the opening of the hazardous waste barrel pierced can change, so that the hazardous waste liquid that may not be completely dumped out of the hazardous waste barrel can flow out due to the change in the opening position, so that the hazardous waste liquid in the hazardous waste barrel can flow out as much as possible. In this way, the moving speed of the movable push plate 17 in the process of pushing the hazardous waste barrel can be controlled, so that the opening of the hazardous waste barrel after being pierced can be maintained at different positions for a certain length of time during the pushing process, so that the hazardous waste liquid in the hazardous waste barrel can flow out as much as possible before being pushed into the hazardous waste barrel collection box 15.

[0111] After the hazardous waste barrel is pushed into the hazardous waste barrel treatment box 2, the first openable baffle 3 and the second openable baffle 4 can be closed, and the first valve 12 and the third valve 14 can be opened. At this time, the delivery pump 10 can be started, and the hazardous waste liquid can pass through the filter 11 to filter out larger solid impurities in the hazardous waste liquid, so as to prevent excessive solid impurities from affecting the normal operation of the delivery pump 10. Thereafter, the delivery pump 10 can re-deliver the hazardous waste liquid to the hazardous waste liquid treatment box 2, and the hazardous waste filter can reduce the impurity particle size allowed to pass through the hazardous waste filter to 3mm by adjusting the position of the mobile filter 8 relative to the fixed filter 7, so as to further filter the solid impurities in the hazardous waste liquid.

[0112] Afterwards, after running for a period of time and the hazardous waste liquid has been circulated and filtered at least once, the hazardous waste filter can reduce the impurity particle size allowed to pass through the hazardous waste filter to 2 mm by adjusting the position of the mobile filter 8 relative to the fixed filter 7, so as to further filter the solid impurities in the hazardous waste liquid.

[0113] After a period of operation, when the hazardous waste liquid has been circulated and filtered at least once, it can be considered that the solid impurities in the hazardous waste liquid have been basically discharged. At this time, the third valve 14 can be closed and the second valve 13 can be opened to transport the hazardous waste liquid to the outside of the hazardous waste dumping and filtering system for further processing. In this way, the hazardous waste liquid can be processed through the hazardous waste dumping and filtering system, the processing efficiency can be improved, and the automatic recovery of the hazardous waste liquid can be realized.

[0114] Reference Figure 4 , showing a schematic diagram of the steps of a hazardous waste dumping and filtering treatment method provided in an embodiment of the present invention, which is applied to a hazardous waste dumping and filtering system, the system comprising: a hazardous waste barrel conveyor belt, a hazardous waste barrel treatment box connected to the hazardous waste barrel conveyor belt, a hazardous waste filter screen arranged at the bottom of the hazardous waste barrel treatment box, a barbed steel plate arranged at the top of the hazardous waste barrel treatment box, and a hazardous waste storage tank arranged below the hazardous waste filter screen; wherein the hazardous waste filter screen comprises a fixed filter screen and a movable filter screen arranged on the upper side or the lower side of the fixed filter screen;

[0115] The method comprises:

[0116] Step 401, transferring the hazardous waste barrel to a hazardous waste barrel treatment box via a hazardous waste barrel conveyor belt;

[0117] Step 402, lowering the barbed steel plate to pierce the hazardous waste barrel, so that the hazardous waste liquid in the hazardous waste barrel flows out; the hazardous waste liquid contains solid impurities of different particle sizes;

[0118] Step 403, adjusting the position of the mobile filter screen relative to the fixed filter screen through the hazardous waste filter screen to adjust the impurity particle size allowed to pass through the hazardous waste filter screen, so that the hazardous waste liquid and solid impurities in the hazardous waste liquid that meet the impurity particle size allowed to pass through flow into the hazardous waste storage tank;

[0119] Step 404, adding an emulsifier into the hazardous waste storage tank to form a stable mixture of the hazardous waste liquid.

[0120] Specifically, in an embodiment of the present invention, the hazardous waste barrel conveyor belt may be intermittently operated to convey a preset number of hazardous waste barrels to a hazardous waste barrel treatment box. The hazardous waste barrel treatment box may be a space for accommodating hazardous waste barrels, which may be provided with a first openable baffle. The first openable baffle may be opened to allow the hazardous waste barrels conveyed by the hazardous waste barrel conveyor belt to be input into the hazardous waste barrel treatment box.

[0121] The hazardous waste barrel can be a container containing hazardous waste liquid, which can usually be made of plastic. The capacity of the container can be determined according to actual needs, such as 100ml, 500ml, 1L, 5L, 10L, 50L, etc., and the present invention does not limit this.

[0122] The number of hazardous waste barrels conveyed by the hazardous waste barrel conveyor belt 1 can be determined based on the amount of hazardous waste liquid that the hazardous waste storage tank can contain and the capacity of the hazardous waste barrel. Generally speaking, the number of hazardous waste barrels conveyed by the hazardous waste barrel conveyor belt 1 can be the amount of hazardous waste liquid that the hazardous waste storage tank can contain / the capacity of the hazardous waste barrel.

[0123] The hazardous waste storage tank may have a maximum amount of hazardous waste liquid that can be accommodated. Generally speaking, the amount of hazardous waste liquid that the hazardous waste storage tank can accommodate can be set equal to the maximum amount of hazardous waste liquid that can be accommodated. If it is necessary to perform a certain degree of pretreatment on the hazardous waste liquid in the hazardous waste storage tank, the amount of hazardous waste liquid that the hazardous waste storage tank can accommodate is lower than the maximum amount of hazardous waste liquid that can be accommodated. The amount of hazardous waste liquid that the hazardous waste storage tank can accommodate can be set to 2 / 3, 1 / 2, 1 / 3, etc. of the maximum amount of hazardous waste liquid that can be accommodated, and the present invention does not impose any limitation on this.

[0124] A barbed steel plate can be provided on the top of the hazardous waste barrel treatment box, and the barbed steel plate can move up and down. Therefore, after the hazardous waste barrel conveyor belt 1 transports the hazardous waste barrel to the hazardous waste barrel treatment box, the barbed steel plate can be lowered to pierce the hazardous waste barrel, so that the hazardous waste liquid in the hazardous waste barrel can flow out.

[0125] In an embodiment of the present invention, the hazardous waste liquid may be a liquid containing components such as organic acids and alkalis, inorganic acids and alkalis, heavy metals, etc. In addition to the liquid, the hazardous waste liquid may also contain solid impurities of different particle sizes. The solid impurities may have a certain adverse effect on the treatment of the hazardous waste liquid. Therefore, the larger solid impurities in the hazardous waste liquid can be separated during the dumping process of the hazardous waste barrel.

[0126] Thus, a hazardous waste filter can be set at the bottom of the hazardous waste barrel treatment box. The hazardous waste filter can include a fixed filter and a movable filter. The fixed filter and the movable filter can be respectively composed of a plurality of steel bars, and there are gaps between the steel bars. Thus, by moving the movable filter left and right, the relative position between the steel bars of the movable filter and the steel bars of the fixed filter can be changed, so that the gap between the steel bars of the fixed filter can be adjusted, so that the particle size of solid impurities allowed to pass through by the hazardous waste filter can be adjusted.

[0127] In the embodiment of the present invention, in order to improve the treatment efficiency of hazardous waste dumping and filtration, solid impurities of a certain particle size can be allowed to pass through the hazardous waste filter. The particle size of the impurities allowed to pass can be determined according to actual needs, such as 5mm, 3mm, 2mm, etc., and the present invention does not limit this.

[0128] After the barbed steel plate pierces the hazardous waste barrel, allowing the hazardous waste liquid to flow into the hazardous waste storage tank, the hazardous waste liquid can be further processed in the hazardous waste storage tank.

[0129] Generally speaking, hazardous waste liquids can contain a variety of different chemical substances, which may have density differences or incompatibilities, making the hazardous waste liquids easy to stratify, affecting the subsequent treatment of the hazardous waste liquids. Therefore, emulsifiers can be added to the hazardous waste storage tanks to form a stable mixture of hazardous waste liquids, so that in the subsequent treatment process, the hazardous waste contained therein will not be fully treated due to the stratification of the hazardous waste liquids.

[0130] In one embodiment of the present invention, a perforated steel plate matching the barbed steel plate is further provided on the top of the hazardous waste barrel treatment box; a plurality of steel barbs are provided on the barbed steel plate, and a plurality of holes matching the steel barbs are provided on the perforated steel plate;

[0131] The step of lowering the barbed steel plate to pierce the hazardous waste barrel so that the hazardous waste liquid in the hazardous waste barrel flows out includes:

[0132] S11, the barbed steel plate is lowered through the barbed steel plate, and the steel spikes on the barbed steel plate pierce the hazardous waste barrel through the holes on the perforated steel plate, and the hazardous waste liquid in the hazardous waste barrel flows out.

[0133] In one embodiment of the present invention, the system further comprises a delivery pump connected to the hazardous waste storage tank;

[0134] The method further comprises:

[0140] S41, when the hazardous waste liquid in the hazardous waste storage tank is transported to the hazardous waste barrel treatment box, the hazardous waste filter is used to adjust the position of the mobile filter relative to the fixed filter to reduce the particle size of impurities allowed to pass through the hazardous waste filter, so that the hazardous waste liquid and solid impurities in the hazardous waste liquid that meet the impurity particle size allowed to pass flow into the hazardous waste storage tank.

[0141] In one embodiment of the present invention, the particle size of impurities initially allowed to pass through the hazardous waste filter is 5 mm, and the particle size of impurities finally allowed to pass through is 2 mm.
