If the granulator is continuously fed, the material will overflow. The existing feeding system stops feeding after conveying a certain amount of material, and then conveys the material again after a period of time. When the feeding system conveys the material again, the material needs to be crushed again, and the equipment needs to be idle for a period of time to wait for the recovery of the material supply, thereby reducing the production efficiency of the prepared product.

[0015] By adopting the above scheme: when the material is too dry, the dust concentration sensor can control the spraying device to increase the humidity of the material to avoid the material from raising dust.
[0016] In one embodiment, the aging warehouse is further provided with a one-way conveying belt connected with the stirring device.
[0017] By adopting the above scheme: when the material in the material box is used up or soaked by rainwater, the material stored in the aging warehouse can be conveyed to the stirring device, so that the granulator can work continuously, save power, and ensure the continuity of production.
[0018] In one embodiment, the air inlet faces the one-way conveying belt connected with the aging warehouse.

[0028] In summary, the present application has the following at least one beneficial technical effect:
[0029] 1. Since the pelletizer needs to frequently open or close the material box during work, it cannot realize continuous feeding. When the material box outputs material again, the material needs to be re-removed from the stone, the equipment needs to be idle for a period of time, and the pelletizer needs to wait for the recovery of the material supply, resulting in low production efficiency. The material level monitoring device can control the reversible conveyor belt to convey the material to the aging warehouse.

When the material is low, the material level monitoring device controls the reversible belt wheel to continuously convey the material to the stirring device.
[0030] 2. Due to the stimulating odor of the material, by setting the air inlet and air outlet in the aging warehouse, the fresh air from the outside is input into the aging warehouse through the air inlet fan, and the stimulating odor inside the aging warehouse is discharged through the air outlet by the air outlet fan. Since the moisture content in the material needs to be controlled during the granulation process, excessive moisture in the material will affect the granulation effect of the granulator. The air inlet fan can dry the material. The spraying device controlled by the dust concentration sensor can prevent dust from being raised by the material. The fan and the spraying device work together to maintain the humidity of the material within a suitable range.
[0031] 3. By setting an anti-overflow chamber with a pressure sensor at the bottom in the material collecting bin and an anti-overflow gap in communication with the anti-overflow chamber, when the material level monitoring device is damaged, when the material is accumulated too high, the excess material can overflow into the anti-overflow chamber from the anti-overflow gap. The weight of the material can start the pressure sensor, and the pressure sensor can control the bidirectional conveying belt to move in the direction of the aging warehouse, further preventing the material from overflowing.

DETAILED DESCRIPTION
[0036] Therefore, it is necessary to provide a stable feeding granulation and aging system with high efficiency.
[0037] Please refer to Figure 1 , Figure 1 is a structure schematic diagram of a stable feeding granulation and aging system provided by the first embodiment of the present application, which comprises a storage part 1, a processing part 2 and a discharge part 3.
[0038] The storage part 1 includes a material box 11 and an aging warehouse 12. The material box 11 is used to store the raw materials to be processed, which can be various forms of open containers. The aging warehouse 12 is used to temporarily store the processed materials for use when needed. The design of the aging warehouse 12 can be selected according to the actual situation, such as flat warehouse or vaulted warehouse, to adapt to different site conditions. The volume of the aging warehouse 12 is not less than that of the material box 11, ensuring that the aging warehouse 12 can accommodate the materials in the material box 11.
[0039] The processing part 2 includes a stone removal and crushing device 21 and a stirring device 22. The stone removal and crushing device 21 is mainly used to remove large particle impurities in the raw materials and crush them into small particles suitable for subsequent processing. This device can use various types of power sources, such as electric motors or hydraulic motors, to provide enough power for crushing operations. The stone removal and crushing device 21 can use a roller crusher or a flat plate crusher, the former is suitable for the initial crushing of larger block materials, and the latter is more suitable for the secondary crushing of small particles.
[0040] The stone removal and crushing device 21 is connected to the material box 11 through a one-way conveyor belt 4, ensuring that the materials are smoothly conveyed from the material box 11 to the crushing device. The materials processed by the stone removal and crushing device are transferred to the two-way conveyor belt 5 by the one-way conveyor belt 4. This conveyor belt can be selected as a belt or a chain, depending on the nature of the material and the conveying distance. Similarly, the stone removal and crushing device 21 is also connected to the two-way conveyor belt 5 through a one-way conveyor belt 4, ensuring that the materials can be smoothly transferred to the next processing link.
[0041] The two-way conveyor belt 5 is a key component that is responsible for conveying materials to the aging warehouse 12 or the stirring device 22. When the amount of material in the material bin 32 is insufficient, the two-way conveyor belt 5 will send the material to the stirring device 22; when the amount of material is excessive, the excess material will be sent to the aging warehouse 12 for temporary storage. This design effectively solves the problem of discontinuous feeding caused by frequent opening of the material box 11 in traditional systems.
[0042] The discharge part 3 includes a granulator 31 and a material bin 32. The granulator 31 is the core equipment of the entire system, which is used to make the mixed materials into the required particle form. The working principle of the granulator 31 is diverse, which can be rotary tabletting, extrusion molding or fluidized bed type, etc. The material bin 32 is an intermediate storage area for collecting materials from the stirring device 22, and controls the running direction of the two-way conveyor belt 5 through the internal material level detection device 321. The material level detection device 321 can be an infrared sensor or other types of photoelectric sensor, which is installed on the side wall of the material bin 32 to monitor the material level in real time.
[0043] The material level detection device 321 includes two, respectively located at the upper and lower ends of the material collecting bin 32. The upper material level monitoring device 321 is used to detect the high material level state, and the lower material level monitoring device 321 is used to detect the low material level state. The two monitoring devices control the running direction of the bidirectional conveying belt 5 through a signal feedback control system, so as to realize the automatic management of the material. If the upper material level monitoring device 321 detects that the material height exceeds the set value, a signal will be sent to the bidirectional conveying belt 5 to send the excess material into the aging warehouse 12; on the contrary, if the lower material level monitoring device 321 detects that the material height is lower than the set value, the bidirectional conveying belt 5 will be controlled to send the material into the stirring device 22.
[0044] The aging warehouse 12 is provided with a unidirectional conveying belt 4 connected with the stirring device 22. When the material in the material box 11 is used up or the material in the material storage part 1 is damp, the material in the aging warehouse 12 can be used to continue the work. Since the material in the aging warehouse 12 has been treated by the stone removing and crushing device 21, the efficiency of transporting the material in the aging warehouse 12 is higher, and the idle period of the equipment is short. While the aging warehouse 12 is working, the staff replenishes the material into the material box 11, which speeds up the production efficiency.
[0045] The working principle of the embodiment is as follows: Since the granulator 31 needs to frequently open or close the material box 11 during work, continuous feeding cannot be realized. When the material box 11 outputs the material again, the material needs to be removed again, the equipment needs to be idle for a period of time, and the granulator 31 needs to wait for the recovery of the material supply, which causes the low production efficiency. When the material feeding and granulating and aging system starts to work, the material box 11 transports the material to the stone removing and crushing device 21 for stone removing and crushing treatment. The stone removing and crushing device 21 transports the material to the bidirectional conveying belt 5, the bidirectional conveying belt 5 transports the material to the material collecting bin 32, and the material level monitoring device in the material collecting bin 32 can control the bidirectional conveying belt 5 to transport the material to the aging warehouse 12. When the material is too high, the bidirectional conveying belt 5 transports the crushed material to the aging warehouse 12 for storage, and when the material is low, the material level monitoring device controls the bidirectional belt wheel to continuously transport the material to the stirring device 22.
[0046] Embodiment 2
[0047] Please refer to Figure 2 , Figure 2For the second embodiment of the application, the internal structure of the aggregate bin is shown in the schematic diagram. This embodiment is basically the same as the above-mentioned embodiment, except that the side wall of the aggregate chute is provided with a sliding groove 3211, which allows the material level detection device 321 to slide up and down inside it. In this way, the staff can flexibly adjust the position of the material level monitoring device 321 according to actual needs, so as to better match the characteristics of different batches of materials. In addition, the aggregate chute is also provided with an anti-overflow chamber 322 and an anti-overflow gap 323 communicating therewith, to prevent the material from overflowing due to being too high. The anti-overflow gap 323 is located near the top of the anti-overflow chamber 322, and once the material reaches this height, it will be guided into the anti-overflow chamber 322, avoiding pollution to the surrounding environment. The bottom of the anti-overflow chamber 322 is provided with a pressure sensor 3221 as a second layer of protection. When the material level monitoring device 321 fails, the material transported by the storage part 1 may overflow and enter the anti-overflow chamber 322, at which time the pressure sensor 3221 will immediately trigger the alarm mechanism and control the bidirectional conveyor belt 5 to send the excess material into the aging warehouse 12, thereby avoiding greater losses.
[0048] Embodiment 3
[0049] Please refer to Figure 3 , Figure 3 For the third embodiment of the application, the internal structure of the aging warehouse is shown in the schematic diagram. This embodiment is basically the same as the above-mentioned embodiments, except that a ventilation system is added in the aging warehouse 12, i.e. an air inlet 121 and an air outlet 122 are provided in the aging warehouse 12, and the air inlet 121 is provided with an air inlet fan 1211, and the air outlet 122 is provided with an air outlet fan 1221. Such a design helps to maintain the air circulation in the aging warehouse 12, expel harmful gases and odors accumulated inside, thereby improving the quality of the stored material.
[0050] Specifically, the air inlet 121 and the air outlet 122 are located on different sides of the aging warehouse 12, forming a good air circulation path. The air inlet 121 is provided with an air inlet fan 1211, which can actively suck in fresh air from the outside when needed, supplement the oxygen content, reduce the temperature, and reduce the risk of microbial reproduction. The air outlet 122 is provided with an air outlet fan 1221 for discharging waste gas in the aging warehouse 12. A filter screen 123 is provided between the air inlet 121 and the air inlet fan 1211, and between the air outlet 122 and the air outlet fan 1221. The main function of the filter screen 123 is to filter out dust and other solid particles in the air, preventing these pollutants from flying out of the aging warehouse 12 and affecting the external production environment. The material of the filter screen 123 can be selected from metal wire mesh or fiber mesh.
[0051] The aging warehouse 12 is also provided with a spraying device 124 controlled by a dust concentration sensor. When the dust concentration in the aging warehouse 12 is too high, the dust concentration sensor sends a signal to activate the spraying device 124 to spray water mist into the air, increase the humidity of the material, and inhibit the flying dust. The spraying device 124 can use high-pressure nozzles or atomizing nozzles to ensure uniform spraying and wide coverage.
[0052] The one-way conveying belt 4 connected to the aging warehouse 12 is located on one side of the air inlet 121. Such a layout is beneficial to the natural air drying of the wet material on the conveying belt using the fresh air brought by the air inlet fan 1211, avoiding the influence of the subsequent processing quality due to the high water content of the material. In addition, the one-way conveying belt 4 can also quickly convey the standby material in the aging warehouse 12 to the stirring device 22 when necessary, ensuring the continuity of production. The fan and the spraying device 124 work together to maintain the humidity of the material within a suitable range, improving the production quality.
[0053] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
