Description

Technical Field

[0001] This utility model relates to the technical field of hazardous waste treatment equipment, and in particular to a sealed pushing structure for a hazardous waste feeding device. Background Technology

[0002] With the acceleration of industrialization, the amount of hazardous waste generated is increasing daily. Due to its toxicity, corrosiveness, flammability, and reactivity, hazardous waste poses a serious threat to the environment and human health if not properly handled. Among various hazardous waste treatment methods, incineration is widely used because it effectively reduces waste volume and toxicity. In the incineration process, the hazardous waste feeding device, as a key front-end equipment, directly affects the stable operation and treatment efficiency of the entire incineration system.

[0003] Traditional hazardous waste feeding devices have revealed numerous problems related to the feeding method during operation. For example, some feeding devices use manual dumping or simple mechanical conveying, which makes it difficult to achieve continuous and stable feeding. Interruptions in feeding often lead to temperature fluctuations in the incinerator, affecting the hazardous waste treatment effect. At the same time, existing devices have poor adaptability to hazardous waste of different shapes and sizes. Some feeding devices lack targeted pretreatment structures. When processing large pieces or highly viscous hazardous waste, it is easy for them to accumulate in the feeding channel, requiring frequent shutdowns for cleaning, which seriously reduces the treatment efficiency. Therefore, we propose a sealed pushing structure for hazardous waste feeding devices. Utility Model Content

[0004] The purpose of this invention is to provide a sealed pushing structure for a hazardous waste feeding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sealed pushing structure for a hazardous waste feeding device includes a base. Fixed support feet are provided on both sides of the top of the base for stable support. An incinerator body for incinerating hazardous waste is located on the top of the fixed support feet on both sides. A feed pipe for hazardous waste entry is provided on one side of the incinerator body. The other end of the feed pipe is connected to a feed box for temporarily storing and pushing hazardous waste. A pushing feeding component is provided on one side inside the feed box to push the hazardous waste to the feed pipe. A feed bucket for holding the hazardous waste to be treated is provided on the top of the feed box. A crushing component is provided inside the feed bucket to crush large pieces of hazardous waste for subsequent pushing. A feed hopper for adding hazardous waste is provided on one side of the top of the feed bucket. A gate assembly for sealing the feed box to prevent hazardous waste leakage and air entry is provided on the top of the feed box and on the other side of the feed bucket.

[0007] As a preferred embodiment of this utility model, a plurality of support legs are fixedly connected between the bottom perimeter of the feed box and the base to support and fix the feed box.

[0008] As a preferred embodiment of this utility model, the feeding assembly includes a feeding chamber opened inside the feeding box, a sleeve installed inside the feeding chamber, a fixing plate provided on one side of the feeding box, and a first drive motor provided on one side of the fixing plate.

[0009] As a preferred embodiment of this utility model, the output end of the first drive motor is connected to a threaded rod, the threaded rod is threadedly connected to the sleeve, a limiting groove is provided at the bottom of the feeding chamber, a slider is provided at the bottom of the sleeve and is slidably connected to the limiting groove, and multiple connecting rods are provided between the fixing plate and the feeding box.

[0010] As a preferred embodiment of this utility model, the pulverizing component includes a rotating shaft, on which multiple sets of cutting blades are sleeved, and a second drive motor is provided at the top of the feed hopper, the output end of which is connected to one end of the rotating shaft.

[0011] As a preferred embodiment of this utility model, the bottom of the feeding barrel is provided with a guide pipe and is connected to the feeding chamber, and the guide pipe is provided with an electromagnetic switch valve.

[0012] As a preferred embodiment of the present invention, the gate assembly includes a support frame disposed on the other side of the top of the feed box, the feed box having a gate slot that closes the feed chamber, a gate being disposed in the gate slot, and a hydraulic cylinder being disposed on the top of the support frame.

[0013] As a preferred embodiment of this utility model, the bottom output end of the hydraulic cylinder is connected to the gate, and the gate is raised and lowered by the extension and retraction of the hydraulic cylinder. The inner side of the support frame is provided with auxiliary sliding grooves on both the front and back sides to assist in the raising and lowering of the gate, and the auxiliary sliding grooves extend into the gate groove. The two ends of the gate on the front and back sides are slidably connected to the auxiliary sliding grooves to ensure that the gate can be stably guided throughout the entire movement process from the inner side of the support frame to the gate groove, thereby achieving precise raising and lowering.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the design of the feeding bucket, feeding hopper, and crushing component allows operators to easily add hazardous waste into the feeding bucket, reducing the risk of spillage during the addition process. The second drive motor in the crushing component drives the rotating shaft to rotate at high speed, causing multiple sets of cutting blades on the rotating shaft to rotate synchronously. This enables efficient cutting and crushing of large pieces of hazardous waste in the feeding bucket, breaking them into smaller particles. This not only facilitates subsequent pushing in the feeding chamber and effectively reduces the possibility of clogging the feeding chamber and feeding pipe, but also allows the hazardous waste to fully contact with air in the incinerator body, achieving more complete combustion and improving the efficiency and volume reduction effect of hazardous waste treatment.

[0016] In the feeding assembly, the feeding chamber provides a dedicated fixed channel for hazardous waste feeding, ensuring that it moves along a predetermined path. The first drive motor is connected to the sleeve via a threaded rod, driving the sleeve to move linearly along the feeding chamber. This allows for precise control of the feeding distance and speed, pushing the waste material towards the feeding tube. The limiting groove and slider work together to precisely guide and limit the movement of the sleeve, preventing deviation or rotation and ensuring accurate feeding direction. The fixing plate provides a stable mounting base for the motor, and the connecting rod enhances the connection strength between the motor and the feeding box, preventing motor vibration from affecting stability and ensuring reliable and stable operation of the assembly.

[0017] The gate assembly's support frame provides stable support for the hydraulic cylinder, while the gate slot provides a precise path for gate movement. The hydraulic cylinder, connected to the gate, delivers strong driving force, ensuring a tight fit between the gate and the gate slot. This effectively prevents external air from entering the incinerator and prevents flue gas from flowing back into the feed box, improving the device's sealing and safety. Auxiliary slideways are slidably connected to both ends of the gate, assisting in guiding the gate's lifting and lowering, ensuring smooth and accurate insertion into the gate slot, further enhancing the sealing effect and guaranteeing the environmental friendliness and stability of the device's operation.

[0027] Example

[0028] like Figures 1-4As shown, this utility model provides a technical solution: a sealed pushing structure for a hazardous waste feeding device, including a base 1, with fixed support feet 101 on both sides of the top of the base 1 for stable support, and an incinerator body 102 for incinerating hazardous waste on the top of the fixed support feet 101 on both sides. A feeding pipe 2 for hazardous waste to enter is provided on one side of the incinerator body 102, and a feeding box 3 for temporarily storing and pushing hazardous waste is connected to the other end of the feeding pipe 2. A pushing feeding component 4 for pushing hazardous waste to the feeding pipe 2 is provided on one side inside the feeding box 3. A feeding bucket 5 for holding hazardous waste to be treated is provided on the top of the feeding box 3. A crushing component 6 for crushing large pieces of hazardous waste for subsequent pushing is provided inside the feeding bucket 5. A feeding hopper 501 for adding hazardous waste into the feeding bucket 5 is provided on one side of the top of the feeding bucket 5. A gate component 7 for sealing the feeding box 3 and preventing hazardous waste leakage and air entry is provided on the top of the feeding box 3 and on the other side of the feeding bucket 5.

[0029] Multiple support legs 301 are fixedly connected to the bottom of the feed box 3 and the base 1 to support and fix the feed box 3.

[0030] The feeding assembly 4 includes a feeding chamber 401 inside the feeding box 3, a sleeve 402 installed inside the feeding chamber 401, a fixing plate 403 on one side of the feeding box 3, and a first drive motor 404 on one side of the fixing plate 403. The feeding chamber 401 provides a dedicated channel for pushing hazardous waste, ensuring that the hazardous waste moves along a fixed path. The sleeve 402 can move along the feeding chamber 401 under the drive of the first drive motor 404, thereby pushing the hazardous waste toward the feeding pipe 2. The fixing plate 403 provides a stable mounting base for the first drive motor 404, ensuring the stability of the motor during operation.

[0031] The output end of the first drive motor 404 is connected to a threaded rod 4041, which is threadedly connected to the sleeve 402. A limiting groove 405 is provided at the bottom of the feeding chamber 401, and a slider 4021 is provided at the bottom of the sleeve 402 and is slidably connected to the limiting groove 405. Multiple connecting rods 406 are provided between the fixed plate 403 and the feeding box 3. The first drive motor 404 drives the threaded rod 4041 to rotate, and the sleeve 402 moves linearly through the threaded transmission, which can accurately control the pushing distance and speed of the sleeve 402. The cooperation between the limiting groove 405 and the slider 4021 guides and limits the movement of the sleeve 402, preventing the sleeve 402 from deviating or rotating during the movement and ensuring the accuracy of the pushing direction. The connecting rods 406 enhance the connection strength between the fixed plate 403 and the feeding box 3, and avoid the vibration generated by the motor operation from affecting the connection stability of the two.

[0032] The crushing assembly 6 includes a rotating shaft 601, on which multiple sets of cutting blades 602 are fitted. A second drive motor 603 is located at the top of the feed hopper 5, and its output end is connected to one end of the rotating shaft 601. The second drive motor 603 drives the rotating shaft 601 to rotate, causing the cutting blades 602 to rotate at high speed, thereby cutting and crushing large pieces of hazardous waste in the feed hopper 5 into smaller particles, which facilitates subsequent pushing in the feed chamber 401 and complete combustion in the incinerator. The multiple sets of cutting blades 602 can improve the crushing efficiency and effect, ensuring that large pieces of hazardous waste are fully crushed.

[0033] The bottom of the feeding hopper 5 is equipped with a guide pipe 502 and is connected to the feeding chamber 401. The guide pipe 502 is equipped with an electromagnetic switch valve 5021. The guide pipe 502 guides the crushed hazardous waste in the feeding hopper 5 into the feeding chamber 401, realizing the orderly transportation of hazardous waste from the feeding hopper 5 to the feeding box 3. The electromagnetic switch valve 5021 can control the opening and closing of the guide pipe 502 through an electrical signal, which makes it convenient for operators to control the timing and amount of hazardous waste falling according to the amount of hazardous waste in the feeding chamber 401, and avoid blockage caused by too much hazardous waste in the feeding chamber 401 or too little hazardous waste affecting the continuity of pushing.

[0034] The gate assembly 7 includes a support frame 701 located on the other side of the top of the feed box 3. The feed box 3 has a gate slot 702 that closes the feed chamber 401. A gate 703 is located in the gate slot 702. A hydraulic cylinder 704 is located on the top of the support frame 701. The support frame 701 provides a stable mounting support for the hydraulic cylinder 704. The gate slot 702 provides a path for the movement of the gate 703. The gate 703 can move along the gate slot 702 under the drive of the hydraulic cylinder 704 to close or open the feed chamber 401. The hydraulic cylinder 704 can provide a large driving force to ensure that the gate 703 fits tightly against the gate slot 702 and ensures a sealing effect.

[0035] The bottom output end of the hydraulic cylinder 704 is connected to the gate 703. The support frame 701 has auxiliary sliding grooves 705 on both the front and back sides. The two ends of the gate 703 on the front and back sides are slidably connected to the auxiliary sliding grooves 705. The hydraulic cylinder 704 directly drives the gate 703 to rise and fall, with fast response and precise control. The sliding connection between the auxiliary sliding grooves 705 and the two ends of the gate 703 plays an auxiliary guiding role in the rise and fall of the gate 703, ensuring that the gate 703 does not deviate during the rise and fall process, and ensuring that the gate 703 can be accurately embedded in the gate groove 702, thereby enhancing the sealing effect.

[0036] The working process of this utility model is as follows: When using the sealed pushing structure of the hazardous waste feeding device, the operator first puts the hazardous waste to be treated into the feeding barrel 5 through the feeding hopper 501. At this time, the gate assembly 7 is in the closed state, and the gate 703 is embedded in the gate groove 702 under the drive of the hydraulic cylinder 704, tightly sealing the feeding chamber 401 to prevent external air from entering the incinerator body 102, and at the same time to avoid hazardous waste leakage during subsequent processing.

[0037] Subsequently, the crushing assembly 6 is started, and the second drive motor 603 starts working. Its output end drives the rotating shaft 601 to rotate at high speed. Multiple sets of cutting blades 602 on the rotating shaft 601 rotate synchronously. The cutting blades 602 cut and crush the large pieces of hazardous waste in the feed hopper 5, breaking them into smaller particles for subsequent pushing and incineration. During the crushing process, the electromagnetic switch valve 5021 is in the closed state to ensure that the hazardous waste is fully crushed in the feed hopper 5 and will not enter the feed chamber 401 in advance.

[0038] Once the hazardous waste is crushed to a suitable particle size, the solenoid valve 5021 opens, and the crushed material in the feed hopper 5 enters the feed chamber 401 of the feed box 3 through the guide pipe 502. The operator can adjust the amount of hazardous waste falling by controlling the opening and closing state of the solenoid valve 5021 according to the amount of hazardous waste in the feed chamber 401, so as to avoid blockage caused by too much hazardous waste in the feed chamber 401 or disruption of the continuous feeding due to too little hazardous waste.

[0039] After a certain amount of broken material accumulates in the feeding chamber 401, the gate assembly 7 starts to work. The hydraulic cylinder 704 retracts, driving the gate 703 to rise along the auxiliary slide 705 and be pulled out from the gate slot 702, opening the channel between the feeding chamber 401 and the feeding pipe 2. The auxiliary slide 705 plays a precise guiding role in the raising and lowering of the gate 703, ensuring that the gate 703 moves smoothly and avoiding deviation that affects the opening and closing effect.

[0040] Next, the feeding assembly 4 is started, and the first drive motor 404 operates. Its output end drives the threaded rod 4041 to rotate. Since the threaded rod 4041 is threadedly connected to the sleeve 402, and the slider 4021 at the bottom of the sleeve 402 slides in the limiting groove 405 at the bottom of the feeding chamber 401, the rotation of the threaded rod 4041 is converted into the linear movement of the sleeve 402 along the feeding chamber 401. The sleeve 402 is pushed towards the feeding pipe 2, pushing the broken material in the feeding chamber 401 towards the feeding pipe 2. The cooperation between the limiting groove 405 and the slider 4021 ensures the accuracy of the pushing direction of the sleeve 402. The connecting rod 406 enhances the connection stability between the fixed plate 403 and the feeding box 3, and avoids motor vibration from affecting the pushing accuracy.

[0041] After the sleeve 402 pushes the crushed material completely into the incinerator body 102 for incineration, the first drive motor 404 reverses, driving the sleeve 402 to move in the opposite direction along the feeding chamber 401 and return to the initial position, in preparation for the next push.

[0042] Subsequently, the gate assembly 7 operates again, the hydraulic cylinder 704 extends, pushing the gate 703 down along the auxiliary slide 705 and re-embedding it into the gate slot 702, sealing the feed chamber 401, preventing high-temperature flue gas or harmful gases in the incinerator body 102 from entering the feed box 3 in reverse, and at the same time preventing external air from entering the incinerator and affecting the combustion state.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
