[0025] Optionally, the first crushing device includes: a first feeder, a first crusher connected to the first feeder, and a second crusher connected to the first crusher; the dry material enters the first crusher through the first feeder for crushing, and then enters the second crusher for further crushing to obtain the first crushed material;

[0045] The above-described solution of this utility model has at least the following beneficial effects:

[0046] The above-described solution of this utility model effectively solves the problem of poor crushing effect in the current pretreatment of industrial waste salt by combining the feeder and the crusher. The squeezing action of the feeder pusher head allows the material to be better gripped by the crusher's blades, preventing material slippage. The downward pressure of the feeder pusher head can break up the plate-like waste salt blocks, significantly improving crushing efficiency. The material mixing device can mix waste salt with different organic matter contents, making the material homogenized. This solves the problem of unstable calorific value caused by poor waste salt mixing, thus making the incineration treatment of industrial waste salt more stable.

[0047] The turntable can precisely separate materials based on their dryness and viscosity. Dry and viscous materials differ significantly in physical properties, making traditional uniform processing methods ineffective. For example, viscous materials tend to clump and clog equipment, while dry materials are relatively loose. After separation by the turntable, dry materials enter the first crushing unit, while viscous materials enter the second crushing unit. This targeted processing makes the crushing process more efficient. The first crushing unit is equipped with a two-stage crusher and a matching feeder for dry materials, better adapting to the characteristics of dry materials and improving crushing efficiency and quality. The second crushing unit is specifically designed for viscous materials, and through specially designed crushers and feeders, it effectively avoids clogging problems during the crushing process.

[0048] After being sorted and crushed, the materials enter the mixing unit. Due to their similar properties, the mixing is more uniform. This is crucial for subsequent incineration, as uniform material mixing ensures stable heat release during incineration, improves the removal efficiency of organic matter, and enhances the purification effect of waste salt, thereby improving the overall economic efficiency of the incineration process.

[0049] The three-way distributor can flexibly output the ton bag material from the mixed material through different outlets according to actual needs. When the ton bags need to be screened out for separate processing, the material is output from the first outlet to the screening equipment. The screening equipment can set an appropriate screen size according to the size of the crushed ton bags to accurately separate the ton bags and the material. The screened material enters the incineration device through the metering screw mechanism and the conveying mechanism, while the ton bags are output through the second belt conveyor. When the ton bags do not need to be screened out for incineration, the material is directly output from the second outlet to the conveying mechanism and enters the incineration device. This flexible conveying and sorting method meets the requirements of different production scenarios and processes, improving the flexibility and adaptability of production.

[0055] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0056] Example 1

[0057] like Figure 1 As shown, an embodiment of this utility model provides a pretreatment system for industrial waste salt incineration, comprising:

[0058] Elevate the material containing industrial waste salt to a preset height and feed it into the feeding device;

[0059] A crushing device connected to the feeding device crushes the material to obtain crushed material;

[0060] A material mixing device connected to the crushing device, wherein the material mixing device mixes the crushed material to obtain a mixed material;

[0061] A material conveying device connected to the material mixing device conveys the mixed material to the incineration treatment device.

[0062] Specifically, the feeding device may include an elevator 1, a tilting mechanism 2, and a stacker 11; the crushing device may include a feeder 4, a primary crusher 5, and a secondary crusher 6; the material conveying device may include a material mixer 7; and the material conveying device may include a metering screw conveyor 9 and a conveyor 10.

[0063] In this embodiment, the material is automatically fed by a feeding device, then crushed by a crushing device, mixed by a mixing device, and finally conveyed to the incineration treatment device by a material conveying device. During the material conveying process, the flow rate of the material conveying device can be determined based on the weight of the mixed material, and the conveying speed of the material conveying device and the feeding speed of the feeding device can be controlled according to the flow rate. This enables automatic feeding and automatic control of the material conveying and feeding speeds based on the material flow rate. As a result, waste salts with different organic contents can be mixed, homogenized, and the feeding, crushing, and conveying of the material can be automatically controlled, thus making the industrial waste salt incineration treatment effect more stable and significantly improving the crushing efficiency.

[0064] In an optional embodiment of this utility model, the feeding device may include:

[0065] Elevator 1, which lifts materials containing industrial waste salt to a preset height;

[0066] The tilting mechanism 2, which is connected to the elevator 1, tilts the tray containing the material so that the material enters the crushing device.

[0067] The pallet fed by the tilting mechanism 2 descends along the elevator 11 or is stacked at a high position to the stacker 11 after being fed by the elevator 1.

[0068] In this embodiment, the flipping mechanism 2 automatically flips the material and drops it into the crushing device, achieving automated material entry into the crushing device. After being fed by the flipping mechanism 2, the pallet descends along the elevator 1 and is conveyed to the stacker crane 11, thus achieving automatic pallet recycling for convenient automatic feeding next time. The elevator 1 can lift the material containing industrial waste salt to a preset height, preparing for subsequent feeding and material processing. The flipping mechanism 2, connected to the elevator 1, flips the pallet containing the material, allowing the material to pour out of the pallet by gravity, enabling the material to smoothly enter the crushing device, achieving effective transfer of material from the lifting stage to the crushing stage. After being fed by the flipping mechanism 2, the stacker crane 11 receives the pallet descending from the elevator 1 and conveys it to a designated location for stacking and storage. This process achieves automatic pallet recycling, facilitating subsequent material feeding cycles, reducing pallet disposal costs, and improving pallet utilization efficiency.

[0069] In an optional embodiment of this utility model, the crushing device includes:

[0070] The feeder 4, connected to the feeding device, is used to receive the material conveyed by the feeding device;

[0071] At least one stage crusher 5 connected to the feeder 4 is used to crush the material conveyed by the feeder 4 to obtain crushed material;

[0072] Specifically, at least the primary crusher 5 includes: a primary crusher 5 connected to the feeder 4 and a secondary crusher 6; wherein, the primary crusher 5 is used to perform primary crushing on the material, and then the material enters the secondary crusher 6 for secondary crushing to obtain the crushed material, reducing the size of the material to the size required by the subsequent process.

[0073] In this embodiment, a crusher with a feeder is used. The material falls into the crusher and the feeder pusher presses the material downward, providing external force to squeeze the whole piece of material towards the crusher blades. This prevents the whole piece of material from slipping on the crusher blades. The downward pressure of the feeder pusher can break up the plate-like waste salt blocks and improve crushing efficiency. To adapt to actual crushing needs, primary crushing, secondary crushing, or even tertiary or higher crushing can be used. The embodiments of this utility model are not limited to secondary crushing.

[0074] In an optional embodiment of this utility model, the crushed material enters a material mixing device to mix the crushed material, and then enters a metal sorting machine 8 connected to the material mixing device to screen the metal objects in the mixed material, thereby obtaining screened material.

[0075] Specifically, the material mixing device includes:

[0076] Mixer cavity;

[0077] A weighing mechanism for weighing the crushed material, placed inside the mixer cavity;

[0078] The material inlet and additive feeding port are provided on the mixer cavity;

[0079] The discharge gate outlet is located on the mixer cavity.

[0080] In this embodiment, the crushed material enters the mixing chamber of the material mixing device for mixing and stirring. After the material is completely homogenized, the discharge gate is opened, and the metal is screened out of the system by the metal separator 8 at the discharge end. Furthermore, the mixing chamber receives materials of different compositions and has an independent additive feeding port. The materials are proportioned by weight according to their oil and water content. The paddles are arranged in a forward and reverse mixing configuration to propel the material forward and stir it. The mixing state of the material is determined by the stirring pressure data. Once a uniform state is achieved, the material is discharged. The discharge gate is controlled by a hydraulic cylinder, allowing it to open from 0-100%. To adapt to the characteristics of waste salt, the lining of the material mixer 7 is made of stainless steel.

[0081] In an optional embodiment of this utility model, the material conveying device includes:

[0082] Measuring screw 9 is connected to the metal sorting machine 8;

[0083] The conveyor 10 is connected to the metering screw 9;

[0084] The metering screw 9 is used to quantitatively transport materials to the conveyor 10, and the conveyor 10 is used to transport the materials to the incineration treatment device.

[0085] In this embodiment, stainless steel is used for the lining and spiral blades of the metering screw 9 to adapt to the characteristics of waste salt.

[0086] The industrial waste salt incineration pretreatment system described in the above embodiments of this utility model uses a forklift to place whole bags of waste salt into the feeding section of the elevator 1, where they are queued for feeding. The feeding section can store multiple ton bags of material, and the material is automatically fed through program control, reducing labor costs. The feeding section is equipped with a weighing function, and an alarm is triggered if the material is overweight. After being lifted, the material reaches the feeding point, where the tilting mechanism 2 tilts the pallet containing the material, allowing the material to enter the crushing device. After feeding, the pallet returns to the ground and is transported to the stacker crane 11 for stacking and recycling. The elevator 1 has a pallet recycling function, allowing the pallets to be reused and reducing disposal costs.

[0087] While the primary crusher 5 and secondary crusher 6 of the crushing device crush the material, the feeder 4 compresses the material. Using a crusher equipped with a feeder 4, the material falls into the crusher, and the pusher head of the feeder 4 presses the material downwards, providing external force to compress the entire piece of material towards the crusher's blades. This prevents the material from slipping on the crusher blades due to the solidified material, thus improving crushing efficiency. By crushing industrial waste salt, crystalline salt and ton bags can be crushed to smaller sizes and then incinerated. This solves the problem of waste salt agglomeration encapsulating organic matter during pyrolysis, leading to incomplete removal of organic matter. It also eliminates the need for further processing of ton bags, increases the pyrolysis rate during incineration, and reduces pyrolysis energy consumption.

[0088] After crushing, materials meeting the required size enter the mixer chamber. The material mixing device mixes and stirs the crushed material. After complete homogenization, the discharge gate is opened, and the mixed material enters the metal separator 8. The metal separator 8 screens out metal objects, and the screened material enters the metering screw 9. The metering screw 9 is used to quantitatively convey the material to the conveyor 10, which is used to transport the material to the incineration treatment device. The material mixer 7 has a weighing function, mixing waste salts with different organic matter contents to homogenize the material. After mixing, it is conveyed to the incinerator to ensure stable furnace temperature during incineration, preventing deflagration and ensuring stable incinerator operation. The crushed and mixed waste salts are fully decomposed in the furnace, efficiently removing organic matter, reducing damage to the incinerator, and improving treatment economy. The metal separator 8 can remove metal objects from the waste salt, providing a stable operating condition for the conveying equipment. The metering screw conveyor 10 can ensure that the material is fed into the conveyor 10 continuously, uniformly and quantitatively; the conveyor 10 can flexibly transport the material to the incinerator without being limited by the space of the site.

[0089] Specifically, the elevator 1 can weigh the material and starts lifting when the weight reaches a set value. To adapt to the characteristics of waste salt, the outer part of the elevator 1's drum that contacts the material is fitted with a corrosion-resistant belt to prevent material spillage and corrosion during transportation. The feeder 4 forces the material to the crushing blades, allowing the material to be gripped and crushed. The crusher is equipped with fixed blades to prevent the ton bags from getting tangled. The material mixing device receives materials of different compositions, judges the mixing state of the materials by the mixing pressure data, and discharges the material after it reaches a uniform state. The discharge gate is controlled by a hydraulic cylinder and can be controlled to open 0-100%. To adapt to the characteristics of waste salt, the lining and spiral blades of the metering screw 9 are made of stainless steel.

[0090] Example 2

[0091] like Figure 2 As shown, an embodiment of this utility model provides a pretreatment system for industrial waste salt incineration, comprising:

[0092] Elevate the material containing industrial waste salt to a preset height and feed it into the feeding device;

[0093] A crushing device connected to the feeding device crushes the material to obtain crushed material;

[0094] A material mixing device connected to the crushing device, wherein the material mixing device mixes the crushed material to obtain a mixed material;

[0095] A material conveying device connected to the material mixing device conveys the mixed material to the incineration treatment device.

[0096] The feeding device may include: a hoist 1 for lifting materials containing industrial waste salt to a preset height; and a depacker 3 disposed between the feeding device and the feeder 4 for depackaging the materials conveyed by the feeding device and then conveying them to the feeder 4.

[0097] Here, the unpacking machine 3 includes: a clamping mechanism that clamps the material at the discharge point of the elevator 1 above the feeder 4; and a milling cutter for cutting the lower end of the material ton bag;

[0098] The clamping mechanism cuts the lower end of the ton bag with a milling cutter, and after the material inside the ton bag falls into the feeder 4, it clamps the ton bag back into the tray on the elevator 1.

[0099] In this embodiment, a depacking machine 3 is installed between the elevator 1 and the feeder 4, enabling direct depacking of materials and their delivery to the feeder 4. A clamping mechanism stably holds the material above the feeder 4, and a milling cutter cuts the lower end of the ton bag, ensuring the material falls precisely into the feeder 4. This prevents spillage and loss during transport, improving material utilization. After the material falls into the feeder 4, the depacking machine 3 clamps the ton bag back into the tray on the elevator 1. This design effectively prevents the ton bags from scattering randomly and impacting the working environment, while also facilitating centralized recycling of the ton bags, meeting environmental protection and production management requirements.

[0100] This embodiment is designed to reduce the risk of damage to equipment such as crushers caused by material spillage and tampering with ton bags. The precise unpacking and material conveying method of the unpacking machine 3 makes the material entering the crusher more regular, reducing the probability of damage to the crusher blades due to irregular material or tampering with ton bags, and extending the service life of the equipment.

[0101] It should be noted that the structure and implementation of the crushing device, material mixing device, material conveying device, material conveying device, metal sorting machine 8, and metering screw 9 in this embodiment are the same as those in Embodiment 1 above, and can achieve the same technical effect, so they will not be described again here.

[0102] Example 3

[0103] like Figure 3 As shown, an embodiment of this utility model provides a pretreatment system for industrial waste salt incineration, comprising:

[0104] The feeding device includes: an elevator 1 for lifting materials containing industrial waste salt to a preset height; and a tilting mechanism 2 connected to the elevator 1.

[0105] The turntable 12, which is connected to the feeding device, is used to separate the material turned down by the turning mechanism 2 to obtain dry material and sticky material.

[0106] A first crushing device and a second crushing device are connected to the turntable 12; wherein, the first crushing device is used to crush the dry material to obtain a first crushed material; the second crushing device is used to crush the sticky material to obtain a second crushed material;

[0107] A material mixing device connected to the first crushing device and the second crushing device is used to mix the crushed first crushed material and the crushed second crushed material to obtain a mixed material;

[0108] A material conveying device connected to the material mixing device, the material conveying device comprising:

[0109] A three-way distributor 19, the inlet of which is connected to the outlet of the material mixing device; a screening device 20 connected to the first outlet of the three-way distributor 19; a second belt conveyor 21 connected to the screening device 20; a metering screw mechanism 23 connected to the screening device 20; and a conveying mechanism 24 connected to the second outlet of the three-way distributor 19 and the metering screw mechanism 23. The three-way distributor 19 outputs the bagged material from the mixed material from the first outlet to the screening device 20. The mixed salt, after being screened by the screening device 20, enters the metering screw mechanism 23, and the material passing through the metering screw mechanism 23 is conveyed to the conveying mechanism 24. The bagged material after being screened by the screening device 20 is conveyed to the second belt conveyor 21. The three-way distributor 19 outputs the bagged material from the mixed material from the second outlet to the conveying mechanism 24. The conveying mechanism 24 conveys the material to the incineration treatment device.

[0110] Specifically, the first crushing device includes: a first feeder 13, a first crusher 14 connected to the first feeder 13, and a second crusher 15 connected to the first crusher 14; the dry material enters the first crusher 14 through the first feeder 13 for crushing, and then enters the second crusher 15 for crushing to obtain the first crushed material.

[0111] The second crushing device includes: a second feeder 17 and a third crusher 18 connected to the second feeder 17; the viscous material enters through the second feeder 17 and enters the third crusher 18 for crushing to obtain the second crushed material.

[0112] The screening device 20 can be a disc screen.

[0113] Furthermore, the preprocessing system also includes:

[0114] The pallet after feeding is transported to the stacker 11 connected to the elevator 1.

[0115] The first crushing device further includes:

[0116] The first belt conveyor 16 is connected to the second crusher 15;

[0117] Metal sorting mechanism 22 connected to the first belt conveyor 16;

[0118] The first belt conveyor 16 transports the screened first crushed material to the metal sorting mechanism 22, which screens the metal in the first crushed material to obtain the screened first crushed material.

[0119] The material mixing device includes:

[0120] Mixer cavity;

[0121] A weighing mechanism for weighing the crushed material, placed inside the mixer cavity;

[0122] The material inlet and additive feeding port are provided on the mixer cavity;

[0123] The discharge gate outlet is located on the mixer cavity.

[0124] Specifically, the screening equipment 20 sets the screen aperture size according to the size of the crushed packaging bag to separate the packaging bag and the material. The screening equipment 20 can beat the material, effectively separating the packaging bag and the material.

[0125] In practice, whole bags of waste salt are placed on the feeding section of elevator 1 by forklift, and the materials are queued for feeding. After being lifted, the material reaches the feeding point, and the tilting mechanism 2 tilts the pallet containing the material, causing the material to fall onto the turntable 12. The turntable 12 separates the material tilted down by the tilting mechanism 2, obtaining dry material and sticky material. The dry material enters the first crushing device, where the first crusher 14 and the second crusher 15 crush the dry material in sequence. The first feeder 13 compresses and feeds the dry material, and the first belt conveyor 16 transports the crushed dry material to the metal sorting mechanism 22, which screens out the metal objects in the crushed dry material. The sticky material enters the second crushing device, where the third crusher... 18. The sticky material is crushed; the screened dry material and the crushed sticky material enter the material mixing device, and the corresponding amount of additive is added from the additive feeding port; the mixed three-way distributor 19 controls the material to be discharged from the first or second discharge port. The material that needs to be screened out of the ton bag for incineration enters the first discharge port. The screening equipment 20 sets the screen hole size according to the size of the crushed ton bag to separate the ton bag and the material. The screened material enters the incineration treatment device after passing through the metering screw mechanism 23 and the conveying mechanism 24 in sequence. The screened ton bag is output through the second belt conveyor 21. The material that does not need to be screened out of the ton bag for incineration enters the second discharge port. The conveying mechanism 24 transports the material that does not need to be screened out of the ton bag for incineration to the incineration treatment device.

[0126] This embodiment introduces a turntable 12, enabling precise separation based on the difference in dryness and viscosity of materials. Dry and viscous materials differ significantly in physical properties, making traditional uniform processing methods ineffective. For example, viscous materials tend to clump and clog equipment, while dry materials are relatively loose. After separation by the turntable 12, dry materials enter the first crushing device, while viscous materials enter the second crushing device. This targeted processing makes the crushing process more efficient. The first crushing device is equipped with a two-stage crusher and a matching feeder for dry materials, better adapting to the characteristics of dry materials and improving crushing efficiency and quality. The second crushing device is specifically designed for viscous materials, and through specially designed crushers and feeders, it effectively avoids clogging problems during the crushing process.

[0127] After being sorted and crushed, the materials enter the mixing unit. Due to their similar properties, the mixing is more uniform. This is crucial for subsequent incineration, as uniform material mixing ensures stable heat release during incineration, improves the removal efficiency of organic matter, and enhances the purification effect of waste salt, thereby improving the overall economic efficiency of the incineration process.

[0128] A metal sorting mechanism 22 is installed in the first crushing unit to effectively remove metal objects from dry materials before they enter the mixing unit. Industrial waste salt often contains metal impurities. If these impurities enter subsequent conveying equipment and incineration units, they may cause equipment wear and malfunctions, affecting normal production. The metal sorting mechanism 22 ensures the stable operation of subsequent conveying equipment, extends equipment service life, and reduces equipment maintenance costs.

[0129] The material mixing device is connected to a unique material conveying device, in which the three-way distributor 19 has a powerful material diversion function. It can flexibly output the ton bag material from the mixed material through different outlets according to actual needs. When the ton bags need to be screened out for separate processing, the material is output from the first outlet to the screening equipment 20. The screening equipment 20 can set an appropriate screen aperture size according to the size of the crushed ton bags, accurately separating the ton bags and the material. The screened material enters the incineration device via the metering screw mechanism 23 and the conveying mechanism 24, while the ton bags are output via the second belt conveyor 21. When the ton bags do not need to be screened out for incineration, the material is directly output from the second outlet to the conveying mechanism 24 and enters the incineration device. This flexible conveying and sorting method meets the requirements of different production scenarios and processes, improving the flexibility and adaptability of production.

[0130] The solution described in this embodiment can adapt to various types of industrial waste salt, whether it is single salt or mixed salt, or waste salt with different packaging forms and material characteristics. It can effectively pre-treat waste salt through processes such as separation by the turntable 12, targeted crushing, and flexible conveying and sorting. This wide applicability allows the system to meet the needs of different enterprises and production scenarios, giving it strong market competitiveness.

[0131] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
