Description

Technical Field

[0001] The present invention relates to the field of sewage treatment, and particularly to a self-driven grille device. Background Art

[0002] In recent years, with the continuous expansion of the scale of the livestock and poultry breeding industry, the problem of manure and sewage treatment has increasingly become one of the main bottlenecks restricting the sustainable development of the industry. According to the statistical data of the Ministry of Agriculture and Rural Affairs, the annual output of manure and sewage from large-scale farms across the country exceeded 1.8 billion tons in 2024, and about 30% of the manure and sewage contains various coarse impurities. These impurities mainly include three categories: one is the biological waste generated during the breeding process, such as vas deferens, fetal membranes, dead fetuses, etc.; the second is the sundries mixed in during the daily management of the farm, such as plastic packaging bags, rubber gloves, feed woven bags, etc.; the third is the bedding residues, such as wood chips, straw segments, etc. If these substances directly enter the subsequent treatment system without effective front-end treatment, they will not only clog key equipment such as solid-liquid separators and biogas reactors, but also accelerate the wear of pump impellers and pipeline valves, resulting in an increase in equipment maintenance frequency by more than 30%, seriously affecting the stable operation of the manure and sewage resource utilization system. More seriously, some non-degradable plastic impurities also enter the farmland with the biogas residue, causing secondary environmental problems such as soil microplastic pollution.

[0003] Currently, the methods for front-end treatment of coarse substances in large-scale livestock and poultry farms are mainly divided into the following two types:

[0004] One is the fixed grille device: As a key facility for the pretreatment of manure and sewage in livestock and poultry farms, the structural design and working principle of the fixed grille device have obvious limitations. This type of device usually adopts a structural form in which columns are rigidly connected to grille plates and is permanently installed through bolts or welding. During specific use, operators need to manually adjust the height of the anti-skid plate according to the actual working conditions, and this adjustment can only be achieved by a simple chute and support bar mechanism for position adjustment within a limited range, making it difficult to adapt to the changes in the characteristics of manure and sewage generated in different seasons or breeding varieties. More prominently, such devices completely rely on manual labor for grille cleaning operations. In the case of large-scale farms with dozens of tons of manure and sewage generated daily, it is often necessary to allocate 2-3 full-time personnel for shift work, which not only increases the labor cost by about 25%, but also brings occupational health risks due to frequent contact with manure and sewage containing high concentrations of pathogens. Actual operation data shows that when the cleaning interval exceeds 4 hours, the average rising speed of the sewage level in front of the grille can reach 15 cm / h, which is extremely likely to cause sewage overflow accidents, especially serious during the rainy season or the concentrated manure cleaning period. In addition, the fixed structure also causes the device to be unable to flexibly adjust the installation position according to the change in the treatment volume, and often faces the dilemma of overall demolition and reconstruction during the expansion or process transformation of the farm.

[0005] Second, it is a mechanical drive device: Most of the existing drive mechanisms adopt independent motors to control the lead screw drive. Although it can achieve the horizontal movement function of the grille, there are many technical defects in actual operation. From the perspective of energy consumption, such drive systems are generally equipped with high-power motors of 2.2 - 3 kW. However, in actual operation, since the grille movement belongs to an intermittent working mode (the single operation time usually does not exceed 5 minutes), the motor is in an inefficient operation range for a long time, and the energy utilization rate is less than 40%, resulting in significant power waste. In terms of maintenance, the lead screw drive mechanism needs to be regularly filled with grease, and it is prone to problems such as thread wear and jamming when exposed to a humid and corrosive environment. Key components need to be replaced on average every quarter. More critically, the existing design completely separates the drive mechanism from the cleaning function, and the grille bars cannot be cleaned synchronously during the movement process, resulting in the need to additionally configure a high-pressure flushing system, which not only increases the equipment investment but also increases the water consumption. Test data shows that the comprehensive operation cost of such traditional drive systems is more than 35% higher than that of the new integrated equipment, which has become the main technical bottleneck restricting the improvement of fecal sewage pretreatment efficiency. Therefore, the present invention provides a self-driving grille device to solve the deficiencies existing in the prior art. Summary of the Invention

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0029] Please refer to Figures 1-7 , an embodiment of the present invention provides a self-driving grille device, including a water inlet mechanism 1, a self-driving mechanism 2 is arranged inside the water inlet mechanism 1, a water outlet mechanism 4 is arranged outside the water inlet mechanism 1, and a grille mechanism 3 is arranged inside the water outlet mechanism 4.

[0030] The water inlet mechanism 1 includes a water inlet channel 101. The water inlet channel 101 has an elevation angle of thirty degrees with the ground. This design is based on the principle of fluid mechanics and can effectively utilize the gravity and the kinetic energy of the water flow. One end of the water inlet pipe 102 is fixedly connected to the water inlet channel 101. The two ends of the water inlet channel 101 are provided with openings, and outer water channels 103 are fixedly connected at both openings. A bend 104 is provided at one end of the outer water channel 103 away from the water inlet channel 101. The bend 104 communicates with the inner water channel 107. A buffer weir 105 is fixedly connected to the inner side of the bend 104. An overflow port 106 is provided on one side of the inner water channel 107. After the waste water is introduced into the water inlet channel 101 by the water inlet pipe 102, the waste water can be quickly and efficiently diverted into the two outer water channels 103. When the waste water flows through the bend 104, the buffer weir 105 fixedly connected to the inner side of the bend 104 will play an important role. By changing the water flow direction and blocking part of the water flow, it effectively slows down the water flow velocity, not only reducing the impact of the water flow on the subsequent structure and protecting the equipment, but also enabling the waste water to pass through the overflow port 106 more smoothly and evenly flow onto the grid plate 302.

[0031] The water outlet mechanism 4 includes a grid tank 401. The outer side of the grid tank 401 is fixedly connected to the outer sides of the two inner water channels 107 for collecting the waste water treated by the grid plate 302. An outlet 402 is provided at one end of the grid tank 401 away from the water inlet channel 101. A filter screen is arranged inside the outlet 402, and the filter screen further filters the fine impurities remaining in the waste water to ensure that the discharged water meets a certain water quality standard.

[0032] The self-driving mechanism 2 includes two rotating rods 201 and a power rod 202. The two ends of the rotating rod 201 are respectively rotatably connected to the inner sides of the outer water channels 103. Blade wheels 203 are arranged on the outer sides of the rotating rod 201 and at both ends of the power rod 202. The two blade wheels 203 are respectively located inside the outer water channels 103 and the inner water channels 107. Cylindrical gears 204 are fixedly connected to one end of the rotating rod 201 and both ends of the power rod 202. The two cylindrical gears 204 mesh with each other. This meshing transmission method can accurately and stably convert the rotation of the rotating rod 201 into the rotation of the power rod 202. When the water flow impacts the blade wheels 203 in the outer water channels 103, the blade wheels 203 rotate rapidly due to the acting force of the water flow. The rotating rod 201, as the support and transmission component of the blade wheels 203, transmits the rotation of the blade wheels 203 to the cylindrical gears 204 connected thereto. After the water passes through the outer water channels 103 and then through the action of the buffer weir 105 at the bend 104, the water flow changes direction and flows into the inner water channels 107, causing the blade wheels 203 on the power rod 202 in the inner water channels 107 to also rotate, and further driving the power rod 202 to rotate.

[0033] The grille mechanism 3 includes two grille chain fixing plates 301 which are arranged inside the grille tank 401. The outer sides of the two grille chain fixing plates 301 are respectively fixedly connected to the inner side of the grille tank 401. On the adjacent sides of the two grille chain fixing plates 301, there is a grille plate 302 which is the main component for intercepting impurities in the wastewater. The two inner sprockets one 303, two inner sprockets two 304 and two inner sprockets three 305 arranged inside it, together with the outer sprocket 309 and the I-shaped wheels on both outer sides of the grille plate 302, constitute a complex and precise transmission system, ensuring the smoothness and accuracy of the grille plate 302 during movement, enabling it to efficiently intercept solid impurities in the wastewater. On the adjacent sides of the two grille chain fixing plates 301, there is a cleaning rod 306 rotatably connected. At both ends of the power rod 202 and both ends of the cleaning rod 306, there are cooperative sprockets 307. A chain is sleeved on the outer circumference of the two cooperative sprockets 307 on the same side. When the power rod 202 rotates, the cooperative sprockets 307 at both ends also rotate accordingly. Through chain drive, the power is transmitted to the cleaning rod 306. A plurality of cleaning brushes 308 are fixedly connected to the outer side of the cleaning rod 306. The rotation of the cleaning rod 306 drives the cleaning brushes 308 to rotate, cleaning the impurities blocked by the grille plate 302. Two outer sprockets 309 are fixedly connected to the outer side of the power rod 202. The outer sprockets 309 are located outside the grille plate 302. A plurality of I-shaped wheels are arranged on both outer sides of the grille plate 302. The inner sprocket one 303, inner sprocket two 304, inner sprocket three 305 and the outer sprocket 309 are all meshed with the I-shaped wheels. The rotation of the power rod 202 drives the outer sprocket 309 to rotate, thereby driving the entire grille plate 302 to move.

[0034] Specifically, taking a livestock farm as an example, the wastewater in the farm is first transported to the inside of the water inlet channel 101 through the water inlet pipe 102. The diameter and material of the water inlet pipe 102 are carefully designed to withstand a certain pressure to ensure the smooth inflow of the wastewater. The water inlet channel 101 has an elevation angle of thirty degrees with the ground. When the wastewater enters the water inlet channel 101, due to the elevation angle, under the combined action of gravity and its own kinetic energy, the wastewater will flow rapidly along the water inlet channel 101, thus quickly diverging into two outer water channels 103. This rapid divergence not only improves the wastewater treatment efficiency but also avoids the accumulation of wastewater in the water inlet channel 101, reducing the risk of blockage.

[0035] After the wastewater enters the external waterway 103, it will flow to the bend 104. When passing through the bend 104, the buffer weir 105 on the inner side of the bend 104 will play an important role. The shape and height of the buffer weir 105 have been precisely calculated. When the wastewater hits the buffer weir 105, the direction of the water flow will change, and part of the water flow will be blocked. This series of actions slows down the flow rate of the wastewater, avoiding excessive impact of high-speed water flow on subsequent equipment. The wastewater with a slowed flow rate can pass through the overflow port 106 more smoothly and flow evenly to the grid plate 302, creating good conditions for subsequent impurity interception.

[0036] At the same time, during the flow of wastewater, under the impact of the water flow, the paddles 203 in the outer waterway 103 will rotate rapidly. The shape and size of the paddles 203 are optimized to maximize the use of the energy of the water flow. The rapid rotation of the paddles 203 drives the rotating rod 201 connected thereto to rotate, and the rotating rod 201 is driven by the cylindrical gear 204 to rotate the power rod 202. The meshing transmission mode of the two cylindrical gears 204 ensures the stability and accuracy of power transmission, ensuring that the power rod 202 can rotate at a predetermined speed and direction. The water passes through the outer waterway 103, and then through the buffer weir 105 at the bend 104, the water flow changes direction and flows into the inner waterway 107, causing the paddles 203 on the power rod 202 in the inner waterway 107 to rotate, and further drives the power rod 202 to rotate.

[0037] The rotation of the power rod 202 brings about two important effects. On the one hand, the outer sprocket 309 on the outside of the power rod 202 rotates, and the outer sprocket 309 engages with the I-shaped wheels on both sides of the outside of the grid plate 302, thereby driving the entire grid plate 302 to move. The movement speed and direction of the grid plate 302 are precisely adjusted to effectively intercept solid impurities in the wastewater. On the other hand, the cooperative sprockets 307 at both ends of the power rod 202 also rotate, and the cooperative sprockets 307 cooperate with the chain to transmit power to the cleaning rod 306, driving the cleaning rod 306 to rotate. The multiple cleaning brushes 308 on the outside of the cleaning rod 306 rotate accordingly to clean the impurities blocked by the grid plate 302. The material and hardness of the cleaning brush 308 are selected to effectively remove impurities without damaging the grid plate 302, ensuring that the grid plate 302 always maintains good filtering performance.

[0038] After the impurities in the wastewater are blocked by the grid plate 302, they are transported to the waste discharge place with the movement of the grid plate 302, and are cleaned by the cleaning brush 308 at the waste discharge place. The cleaned impurities can be collected and processed centrally, avoiding the accumulation of impurities in the equipment and affecting the normal operation of the equipment.

[0039] Finally, the wastewater filtered by the grid plate 302 will flow into the grid tank 401. The volume of the grid tank 401 is designed to accommodate a certain amount of wastewater, providing a buffer for subsequent treatment. After staying in the grid tank 401 for a period of time, the wastewater will be discharged through the water outlet 402 at one end of the grid tank 401. The filter screen installed inside the water outlet 402 will further filter the fine impurities remaining in the wastewater, ensuring that the discharged water meets certain water quality standards and reducing environmental pollution.

[0040] Working principle: Taking a livestock farm as an example, first, the wastewater in the farm will be transported through the water inlet pipe 102 to the inside of the water inlet channel 101. The water inlet channel 101 has an elevation angle of thirty degrees with the ground, which can cause the wastewater to quickly flow into the two outer water channels 103. Then, when passing through the bend 104, it will be buffered by the buffer weir 105 to slow down the water flow rate. Finally, the wastewater will flow onto the grid plate 302 through the overflow port 106. At the same time, under the impact of the water flow, the paddle blades 203 in the outer water channels 103 will rotate rapidly, and through the transmission of the two cylindrical gears 204, the power rod 202 will rotate. Moreover, the paddle blades 203 in the inner water channel 107 will also rotate with the water flow, further driving the power rod 202 to rotate. The rotation of the power rod 202 can cause the outer sprocket 309 to drive the entire grid plate 302 to move. Also, driven by the power rod 202, the two cooperative sprockets 307 cooperate with the chain to transmit the power to the cleaning rod 306, thereby driving multiple cleaning brushes 308 to rotate. In this way, after the impurities in the wastewater are blocked by the grid plate 302, they will be cleaned by the cleaning brushes 308 at the waste discharge location, and finally, the wastewater from which the solid impurities have been removed will be discharged at the water outlet 402 at one end of the grid tank 401.
