Description

Technical Field

[0001] This utility model relates to the field of biogas residue drying and pulverizing technology, and more specifically, to a biogas residue drying and pulverizing linkage unit. Background Technology

[0002] With the increasing awareness of environmental protection and the development of the clean energy industry, biogas projects are being used more and more widely, and the amount of biogas residue produced is also increasing. Biogas residue is rich in nutrients such as nitrogen, phosphorus, and potassium, as well as organic matter, and is a potential high-quality fertilizer and industrial raw material. However, untreated biogas residue has a high water content and large volume, which not only easily breeds bacteria and emits odors, causing environmental pollution, but also seriously limits its storage, transportation and subsequent resource utilization.

[0003] Currently, the treatment of biogas residue usually involves drying it first to reduce its moisture content, and then crushing it into a suitable particle size. However, most of the existing drying and crushing equipment operate independently. Manual material handling is not only labor-intensive and inefficient, but also prone to material spillage and pollution of the working environment. There is a lack of effective connection between the equipment, resulting in long processing cycles and high energy consumption. At the same time, a single crushing method is difficult to ensure uniform particle size of biogas residue, which affects the subsequent use effect.

[0004] This invention can effectively reduce labor costs and improve the drying and pulverizing efficiency of biogas residue. Utility Model Content

[0005] The present invention aims to solve the technical problems mentioned in the background art and provide a biogas residue drying and crushing linkage unit.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biogas residue drying and crushing linkage unit, including a drying box and a crushing box located next to the drying box. The bottom of both the drying box and the crushing box are fixedly installed with brackets. A conveyor is provided between the drying box and the crushing box. The beginning of the conveyor is installed on the side of the drying box, and the end of the conveyor is installed on the upper part of the crushing box.

[0007] The advantages of this utility model are:

[0008] 1. Equipped with a conveyor, one end fixed to the side of the drying chamber and the other end fixed to the top of the crushing chamber, the conveyor automatically transfers the biogas residue from the drying stage to the crushing stage through its own transmission mechanism. This automated transfer eliminates the need for manual intervention, significantly reducing the labor intensity of operators and avoiding material spillage and contamination problems that occur during manual transfer. Furthermore, the conveyor precisely coordinates with the guide plate at the discharge port of the drying chamber and the guide plate and limiting frame at the feeding port of the crushing chamber. The inclined design of the guide plate allows the dried biogas residue to slide smoothly onto the conveyor belt, while the guide plate and limiting frame guide and limit the biogas residue, ensuring its accurate entry into the crushing chamber. This ensures smooth and accurate material transfer, preventing material accumulation due to poor conveying and improving the overall operating efficiency of the unit. The conveyor tightly connects the drying and crushing stages, enabling combined operations, shortening the biogas residue processing cycle, and improving production efficiency.

[0009] 2. By incorporating a stirring group, consisting of a first motor, stirring rod, and stirring blades, installed inside the drying chamber, the first motor is activated when the biogas residue enters the drying chamber through the feed inlet. The stirring rod drives the stirring blades to rotate, continuously agitating the biogas residue. This ensures that the biogas residue comes into full contact with the heat generated by the heating pipes on the inner wall of the drying chamber, greatly improving the uniformity and efficiency of drying. This avoids localized insufficient or excessive drying of the biogas residue during the drying process, ensuring the drying quality. Simultaneously, the biogas residue is fully dispersed during the stirring process, which helps the filter holes on the partition plate to filter the moisture in the biogas residue, further improving the drying effect. The stirring group ensures that the biogas residue in the drying chamber is fully processed, providing higher quality material for the subsequent crushing stage, and ensuring the effectiveness and quality of the entire unit in processing biogas residue.

[0010] 3. By setting up a partition, which is fixedly installed inside the drying box and has several filter holes, the partition divides the inside of the drying box into upper and lower parts, making the biogas residue in the drying box more evenly distributed, increasing the contact area between the biogas residue and the heating pipe, which helps to improve the drying efficiency. The filter holes on the partition can filter the moisture in the biogas residue, accelerate the moisture discharge speed, further improve the drying effect, and improve the practicality and adaptability of the unit.

[0011] 4. In summary, this biogas residue drying and crushing unit, through the installation of conveyors and other structures, achieves automated operation. From biogas residue feeding to finished product collection, no manual handling is required, significantly reducing labor intensity, improving production efficiency, and shortening the processing cycle. The mixing group and baffles work together to make the biogas residue drying more uniform and efficient. The filter holes can also separate impurities and accelerate dehydration. The conveyor precisely connects the drying and crushing stages to avoid material spillage and accumulation. The crushing group has multiple crushing rollers working together to ensure thorough crushing and uniform particle size. The secondary crushing and screening design ensures stable finished product quality. Attached Figure Description

[0017] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0018] Please see Figure 1-4 In this embodiment of the utility model, a biogas residue drying and crushing linkage unit includes a drying box 1 and a crushing box 2 located next to the drying box 1. The bottom of both the drying box 1 and the crushing box 2 are fixedly installed with a bracket 3. A conveyor 4 is arranged between the drying box 1 and the crushing box 2. The beginning of the conveyor 4 is installed on the side of the drying box 1, and the end of the conveyor 4 is installed on the upper part of the crushing box 2.

[0019] The crushing box 2 is equipped with a sieve plate 202 inside, and a guide tube 203 is fixedly installed at the bottom of the sieve plate 202. The inside of the guide tube 203 is conical.

[0020] The drying chamber 1 has an inlet 101 and two outlets 102 on its top and side, respectively. A partition 103 is fixedly installed inside the drying chamber 1 and several heating tubes 104 are fixedly installed on the inner wall. Several filter holes are opened on the partition 103. Solenoid valves are installed at both outlets 102.

[0021] The bottom of the conduit 203 is fixedly embedded with a discharge pipe 204, the bottom of the discharge pipe 204 penetrates the bottom of the crushing box 2, and a collection box is provided at the bottom of the discharge pipe 204.

[0022] A branch pipe 205 is embedded in the side of the crushing box 2, and a secondary collection box 206 is provided at the other end of the branch pipe 205. An electromagnetic valve is embedded inside the branch pipe 205.

[0023] When using this device, the biogas residue enters the drying chamber 1 through the feed inlet 101 at the top. Several heating tubes 104 are fixedly installed on the inner wall of the drying chamber 1. When the heating tubes 104 are energized, they generate heat to dry the biogas residue inside the drying chamber 1. Simultaneously, the partition 103 inside the drying chamber 1 has several filter holes that filter out excess moisture from the biogas residue. Once the biogas residue has been dried to a certain extent, it is discharged from the discharge outlet 102. After being discharged from 102, the residue directly enters the conveyor 4, which is fixedly connected to the side of the drying chamber 1. The conveyor 4, relying on its own transmission mechanism, transports the biogas residue from one end of the drying chamber 1 to the upper end of the crushing chamber 2, achieving automatic transfer of the biogas residue from the drying stage to the crushing stage without manual intervention. After entering the crushing chamber 2 via the conveyor 4, the biogas residue is crushed by mechanical force within the crushing chamber 2. The crushed biogas residue falls onto the sieve plate 202, which screens the crushed biogas residue. Biogas residue with the required particle size passes through the sieve plate 202. The sludge falls into the guide tube 203 fixedly installed at the bottom of the sieve plate 202. Since the inside of the guide tube 203 is conical, it helps the sludge to slide down smoothly. It is discharged from the crushing box 2 through the discharge pipe 204 fixedly embedded at the bottom of the guide tube 203 and finally falls into the collection box set at the bottom of the discharge pipe 204 for collection. The sludge that does not meet the particle size requirements stays above the sieve plate 202 for further processing. For the sludge that does not meet the particle size requirements that stays above the sieve plate 202, the electromagnetic valve embedded in the side branch pipe 205 of the crushing box 2 can be opened to allow the sludge to enter the secondary collection box 206 for collection through the branch pipe 205. After the secondary collection box 206 is full, it is selected to return to the crushing box 2 for screening again to ensure that the particle size of the finally collected sludge meets the usage requirements. From the time the sludge enters the drying box 1 to the time the sludge that meets the particle size requirements is finally collected, the whole process does not require manual material transfer, which greatly reduces the labor intensity of the operators and improves the production efficiency. Compared with traditional independently operated drying and crushing equipment, it can significantly shorten the sludge processing cycle.

[0024] In this embodiment of the utility model, one of the discharge ports 102 is higher than the partition 103 and is equipped with a guide plate 105. The outer end of the guide plate 105 is located above the conveyor belt of the conveyor 4, and the outer side of the guide plate 105 is inclined. The inner end face of the guide plate 105 is flush with the surface of the partition 103. The other discharge port 102 is located below the partition 103.

[0025] The drying chamber 1 is equipped with a stirring group 5, which includes a first motor 501, a stirring rod 502 and a stirring plate 503. The first motor 501 is installed at the top of the drying chamber 1. One end of the stirring rod 502 passes through the top of the drying chamber 1 and is fixedly connected to the first motor 501, and the other end is located above the partition 103. The stirring plate 503 is connected to the outer periphery of the stirring rod 502.

[0026] The crushing box 2 has a feeding port 201 at the upper end, and the conveyor 4 has a guide plate 401 fixedly installed at the end. The guide plate 401 is located above the feeding port 201, and a limit frame 402 is nested on the outer surface of the guide plate 401. The limit frame 402 is fixed to the side of the conveyor 4, and the bottom of the limit frame 402 is hollow.

[0027] After the biogas residue enters the drying chamber 1 through the feed inlet 101 at the top, the first motor 501 is started. The first motor 501 drives the stirring rod 502 to rotate. The stirring blades 503, which are fixed to the outer surface of the stirring rod 502 by bolts, stir the biogas residue. During the stirring process, the biogas residue is constantly turned over, making full contact with the heat generated by the heating tubes 104 fixedly installed on the inner wall of the drying chamber 1, thus accelerating the drying speed. At the same time, the partition 103 set inside the drying chamber 1 has several filter holes that further filter the moisture in the biogas residue, thereby effectively improving the drying efficiency of the device. After drying to a certain extent, due to one of the... A guide plate 105 is fixedly installed at the bottom of the discharge port 102. The other end of the guide plate 105 is located above the conveyor belt of the conveyor 4, and the outer side of the guide plate 105 is inclined. The upper surface of the guide plate 105 is at the same level as the upper surface of the partition plate 103. The dried biogas residue located above the partition plate 103 can be pushed onto the guide plate 105 through the discharge port 102 by the pushing of the stirring plate 503, and then slide down onto the conveyor belt of the conveyor 4 through the guide plate 105. The filtered water located below the partition plate 103 is discharged through another discharge port 102. After the conveyor 4 is started, it relies on its own transmission mechanism to push the conveyor belt... The biogas residue is conveyed forward. A guide plate 401 is fixedly installed at the other end of the conveyor 4. The guide plate 401 is located above the feeding port 201 at the upper end of the crushing box 2. A limiting frame 402 is nested on the outer surface of the guide plate 401. The limiting frame 402 is fixed to the side of the conveyor 4 by bolts. The bottom of the limiting frame 402 is hollow. During transportation, the biogas residue is guided by the guide plate 401 and limited by the limiting frame 402, allowing it to accurately enter the crushing box 2 through the feeding port 201, preventing spillage during transportation. This allows the biogas residue to enter the crushing box 2 for crushing. The mixing group 5 ensures that the biogas residue is properly crushed in the drying box 1. The internal components are thoroughly stirred, ensuring uniform contact between the biogas residue and heat, avoiding insufficient or excessive drying in certain areas, thus significantly improving drying efficiency and quality. The inclined design of the guide plate 105 and its precise docking with the conveyor belt of the conveyor 4 ensure that the dried biogas residue can smoothly and accurately enter the conveyor 4, avoiding material accumulation or spillage due to poor conveying. The setting of the guide plate 401 and the limiting frame 402 allows the biogas residue to be guided and limited when entering the crushing box 2, effectively preventing the biogas residue from scattering during the conveying process, reducing material waste, and also reducing the difficulty and frequency of cleaning work.

[0028] In this embodiment of the present invention, a crushing assembly 6 is provided inside the crushing box 2. The crushing assembly 6 includes a second motor 601, multiple crushing rollers 602, transmission wheels 603, and transmission belts 604. A rotating rod 606 is fixedly installed at the output end of the second motor 601. Two transmission wheels 603 are coaxially connected to the end of the rotating rod 606. Two transmission belts 604 are respectively embedded inside the two transmission wheels 603, and each of the two transmission belts 604 is also embedded with a transmission wheel 603. A connecting rod 605 is coaxially installed on any transmission wheel 603. The connecting rod 605 is rotatably installed on the side wall of the crushing box 2, and the end of the connecting rod 605 is also connected to the crushing rollers 602.

[0029] After the biogas residue enters the crushing box 2, the second motor 601 is started. The rotating rod 606 at the output end of the second motor 601 drives the two transmission wheels 603 connected to it to rotate. Through the transmission belt 604, the other transmission wheels 603 rotate synchronously. The connecting rod 605 fixedly installed on the other side of each transmission wheel 603 drives the crushing roller 602 to rotate. Since the crushing rollers 602 are intermeshing with each other, when the biogas residue falls into the crushing box 2, it is crushed under the squeezing and shearing action of multiple sets of intermeshing crushing rollers 602. The crushed biogas residue falls to the screen plate 202. The screen plate 202 screens the crushed biogas residue. Biogas residue with the required particle size passes through the screen plate 202 and falls into the guide tube 203 fixedly installed at the bottom of the screen plate 202. Since the inside of the guide tube 203 is conical, it helps the biogas residue to slide down smoothly. It is discharged from the crushing box 2 through the discharge pipe 204 fixedly embedded at the bottom of the guide tube 203 and finally falls into the screen. The sludge is collected in the collection box at the bottom of the inlet / outlet pipe 204, while the sludge that does not meet the particle size requirements remains above the sieve plate 202 for further processing. For the sludge that does not meet the particle size requirements remaining above the sieve plate 202, the electromagnetic valve embedded in the side branch pipe 205 of the crushing box 2 can be opened to allow the sludge to enter the secondary collection box 206 through the branch pipe 205. The secondary collection box 206 returns to the crushing box 2 for screening again. Multiple intermeshing crushing rollers 602 in the crushing group 6 work together to crush the sludge through various methods such as extrusion and shearing. Compared with a single crushing method, it can crush the sludge to the required particle size more quickly and thoroughly, greatly improving the crushing efficiency. At the same time, the setting of multiple crushing rollers 602 makes the crushing process more uniform, effectively avoiding the situation of insufficient or excessive crushing of some sludge, ensuring that the particle size of the crushed sludge is uniform and improving the crushing quality.

[0030] Working principle: The biogas residue enters through the feed inlet 101 at the top of the drying chamber 1. The first motor 501 is started, and the stirring rod 502 of the stirring group 5 drives the stirring blades 503 to agitate the biogas residue, ensuring it makes full contact with the heating pipes 104 on the inner wall for drying. The filter holes on the partition 103 assist in filtering moisture from the biogas residue. When there is too much water at the bottom of the partition 103, it is discharged by controlling the solenoid valve of one of the discharge ports 102. After the drying degree is reached, the solenoid valve of the discharge port 102 is controlled, and the stirring group 5 is started simultaneously, transferring the biogas residue onto the guide plate 105. The biogas residue slides down the guide plate 105 to the conveyor 4. After the conveyor 4 is started, it relies on the transmission mechanism to transport the biogas residue. Guided by the guide plate 401 and limited by the limiting frame 402, the biogas residue accurately enters the feed inlet 201 at the top of the crushing chamber 2. The biogas residue entering the crushing box 2 is driven by the second motor 601. The rotating rod 606 drives the transmission wheel 603, which in turn drives multiple sets of crushing rollers 602 to mesh and rotate via the transmission belt 604. This crushes and shears the biogas residue, which then falls onto the sieve plate 202 for screening. Biogas residue that meets the particle size requirements passes through the sieve plate 202 and falls into the collection box along the conical guide pipe 203 and the discharge pipe 204. Biogas residue that does not meet the requirements remains above the sieve plate 202. After opening the solenoid valve of the branch pipe 205, it enters the secondary collection box 206. After secondary crushing, it can return to the crushing box 2 for screening again, ensuring that the particle size of the finally collected biogas residue meets the requirements. The entire process realizes the automated linkage of biogas residue drying, conveying, crushing, screening and secondary crushing, eliminating the need for manual material transfer and efficiently completing the biogas residue treatment.
