[0030] First Embodiment
[0031] Please refer to Figure 1 ,a packaging system for granular feed, which includes a packaging device 10, a hoist, and a granulator. Among them, the packaging device 10 includes a finished product bin 100, a grading screen 200, a buffer bin 300, and a packaging machine 400; among them, the grading screen 200 is arranged between the finished product bin 100 and the buffer bin 300.
[0032] The finished product bin 100 is provided with a finished product bin feed inlet 101 and a finished product bin discharge outlet 103. In this embodiment, the finished product bin feed inlet 101 is arranged above the finished product bin discharge outlet 103, and the caliber of the finished product bin feed inlet 101 is larger than that of the finished product bin discharge outlet 103, presenting an inverted horn shape.
[0033] It should be noted that the inverted horn-shaped setting of the finished product bin 100 in this embodiment can slow down the falling speed of the finished feed; in other embodiments of the present invention, the structure of the finished product bin 100 can be reasonably adjusted according to actual needs.
[0034] The finished product bin 100 is also provided with a gate and a gate controller. Specifically, the gate controller is connected to the gate and arranged at the finished product bin discharge outlet 103. The gate controller can control the opening and closing of the gate, and thus control whether the material is released. This setting is used on the one hand to control the feeding amount and feeding speed of the material to avoid the explosion or emptying of the buffer bin 300, and on the other hand to reduce the pressure between the finished feed in the grading screen 200 and the buffer bin 300, and reduce the powder content rate of the finished feed.
[0035] The finished product bin discharge outlet 103 is above the grading screen feed inlet 201 and is connected to the grading screen feed inlet 201 through a first conveying pipe 105; the first conveying pipe 105 is inclined, and the included angle between it and the feed inlet of the grading screen 200 is 45°. The setting of the included angle is used to slow down the falling speed of the material and reduce the powder content rate of the feed finished product.
[0036] It should be noted that the inclination angle of the first conveying pipe 105 can be reasonably selected according to the actual material to be conveyed; in other embodiments of the present invention, an inverted horn-shaped transmission part can be connected at the grading screen feed inlet 201. Among them, the discharge outlet of the finished product storage bin abuts against the inner wall of the large mouth of the horn, and the small mouth of the horn is connected to the grading screen feed inlet 201. The connection method is not particularly limited, and detachable methods such as snap connection and threaded connection can be selected, or fixed methods such as welding can also be used. The horn-shaped transmission part has the same function as the inclined conveying pipe, which is to slow down the falling speed of the material and reduce the powder content rate of the feed finished product.
[0037] The grading sieve 200 includes a detachable sieve mesh 202, sieve plates 204, and a vibrator (not shown in the figure); the sieve mesh 202 and the sieve plates 204 are respectively connected to a vibrator, and the vibrator is arranged at one end of the sieve mesh 202 or the sieve plates 204 away from the feed inlet 201 of the grading sieve.
[0038] It should be noted that the use of the vibrator can accelerate the transmission speed of materials on the sieve mesh 202 or the sieve plates 204, and can also reduce the powder content in the qualified materials output from the first discharge port 203. The present utility model does not make special limitations on the sieve mesh 202, and a sieve mesh 202 with a suitable specification can be selected for operation according to the particle size of the finished feed actually processed; the specifications of the vibrator can also be reasonably adjusted according to actual needs.
[0039] The sieve mesh 202 and the sieve plates 204 are respectively abutted against the inner side of the sieve wall of the grading sieve 200; it should be noted that the connection between the sieve mesh 202, the sieve plates 204 and the sieve wall of the grading sieve 200 is a detachable connection method, which is convenient for replacing the sieve mesh 202 with different pore diameters for different particle sizes of the finished feed and reasonably selecting according to actual needs; the sieve mesh 202 is arranged above the sieve plates 204; since the materials received by the sieve plates 204 are mostly sieved materials and are mostly powdery, the sieve plates 204 in this embodiment are provided without holes.
[0040] Specifically, the sieved materials in the grading sieve 200 are transported to the granulator through a hoist for re-granulation, recycling the powdered feed, reducing material waste and saving production costs at the same time.
[0041] In this embodiment, the finished feed has been screened before entering the packaging device 10 for processing, so the grading sieve 200 in this embodiment only needs to be screened once with the sieve mesh 202. In other embodiments of the present utility model, the number of the sieve mesh 202 and the sieve plates 204 in the grading sieve 200 can be reasonably set according to actual needs.
[0042] In this embodiment, the sieve mesh 202 and the sieve plates 204 are inclined in the same or opposite directions inside the grading sieve 200, and the inclination angle is 30°. One end of the sieve mesh 202 close to the feed inlet 201 of the grading sieve is higher than the end of the sieve mesh 202 close to the first discharge port 203, and the lower end of the sieve mesh 202 is connected to the first discharge port 203, which is convenient for the output of qualified materials; one end of the sieve plates 204 close to the second discharge port 205 is lower than the other end of the sieve plates 204, and the lower end of the sieve plates 204 is connected to the second discharge port 205, which is convenient for the sieved materials to be transported to the hoist through the third conveyor pipe.
[0043] If the screen 202 and the screen plate 204 are arranged in the same direction inside the grading screen 200, the first discharge port 203 and the second discharge port 205 will be arranged on the same side of the grading screen 200; if the screen 202 and the screen plate 204 are arranged in opposite directions inside the grading screen 200, the first discharge port 203 and the second discharge port 205 will be arranged on different sides of the grading screen 200; it should be noted that the setting directions of the two need to be reasonably adjusted according to the actual site size and the convenience of worker operation.
[0044] The grading screen 200 transports the qualified material from the first discharge port 203 to the buffer bin 300. Specifically, it enters the buffer bin 300 through the second feed pipe 207 from the buffer bin feed inlet 301; the second feed pipe 207 is inclined and the included angle with the buffer bin feed inlet 301 is 30°.
[0045] It should be noted that in other embodiments of the present invention, the buffer bin feed inlet 301 can be connected to an inverted horn-shaped transmission member. Among them, the first discharge port 203 abuts against the inner wall of the large mouth of the horn, and the small mouth of the horn is connected to the buffer bin feed inlet 301. The connection method is not particularly limited, and detachable methods such as snap connection and threaded connection can be selected, or fixed methods such as welding can also be used. The horn-shaped transmission member has the same function as the inclined feed pipe, which is used to slow down the falling speed of the material and reduce the powder content rate of the feed product.
[0046] In addition, in the embodiment of the present invention, the grading screen 200 is arranged between the finished product bin 100 and the buffer bin 300, which can effectively buffer the impact force of the feed during the falling process and reduce the powder content rate in the finished product packaging.
[0047] The buffer bin 300 is provided with a level controller, which is communicatively connected to the gate controller; further, the level controller includes an upper level controller 303 and a lower level controller 305 to realize automatic control of the output of the material.
[0048] Specifically, the upper level controller 303 is communicatively connected to the gate controller and is used to close the gate to stop discharging; the lower level controller 305 is communicatively connected to the gate controller and is used to open the gate to discharge. The coordinated use of the gate controller and the level controller facilitates real-time monitoring of the specific amount of material in the buffer bin 300, and then reasonably controls the discharging situation of the finished product bin 100, avoiding empty bin or explosion of the buffer bin 300 and maintaining a normal and orderly production rhythm; at the same time, it can also avoid particle breakage caused by stacking and extrusion in the feed room. While improving product quality and customer satisfaction, it reduces feed waste and saves resources.
[0049] Furthermore, the level controller is selected from any one of a capacitance level gauge, a rotary vane level gauge, a laser level gauge, and an ultrasonic level gauge. It should be noted that in the implementation mode of the present utility model, a capacitance level gauge is selected. In other modes of the present utility model, the specifications of the level gauge can be reasonably adjusted according to actual situations.
[0050] The capacitance level gauge is based on the principle of capacitance measurement. By inserting the probe into the storage tank, the capacitance formed between the metal probe in contact with the material and the outer metal storage tank wall is used to measure the actual height of the material. This type of level gauge is suitable for materials that are not prone to caking, volatilization, and easy adhesion, such as liquid, granular, and powdered materials.
[0051] The principle of the gate controller and the level controller working together is as follows:
[0052] When the material in the buffer bin 300 is lower than the lower level controller 305, the gate controller in the finished product bin 100 controls the gate to open for discharging. The finished feed is transported through the first feed pipe 105 to the classifier for screening; the vibrating device drives the screen 202 to vibrate together to separate the screened material and the qualified material; among them, the qualified material is connected to the buffer bin 300 through the second feed pipe 207, and then is transported to the packing scale of the packing machine 400 through the buffer bin 300. After weighing to the specified weight, it can be packed; the screened material is connected to the elevator through the third feed pipe and further transported to the granulator for re-granulation treatment.
[0053] When the material in the buffer bin 300 is higher than the upper level controller 303, the gate controller in the finished product bin 100 controls the gate to close, and the classifier 200 continues to work for 10 seconds; after 10 seconds, the gate in the finished product bin 100 opens, and discharging continues. The classifier 200 continues to work until the material in the buffer bin 300 is higher than the upper level controller 303, then the gate closes; this cycle repeats until all the material in the finished product bin 100 is discharged, the gate closes, and the classifier 200 continues to vibrate until all the material in the buffer bin 300 is packed, and the equipment shuts down and stops running.
[0054] It should be noted that the cooperation between the gate controller and the level controller is carried out through the way of communication transmission. In the embodiment of the present utility model, the control of the feed in the finished product bin 100 is realized through the mutual conversion of pressure signals and electrical signals. In other implementation modes of the present utility model, it can be reasonably adjusted according to actual needs.
[0055] In this embodiment, the feed inlet 401 of the packing machine is connected to the discharge outlet of the buffer bin 300 for packing the qualified material output from the buffer bin 300.
[0056] It should be noted that a weighing component is provided at the discharge port 403 of the packaging machine for quantitatively weighing the output pellet feed and then performing packaging treatment.
[0057] The working principle of the dispensing device 10 provided by the present utility model is as follows:
[0058] According to the level of the material in the buffer bin 300, the gate controller in the finished product bin 100 is controlled to control the opening and closing of the gate, thereby controlling the feeding amount and feeding speed of the feed. At the same time, the vibration of the grading screen 200 is coordinated to reduce the impact force of the pellet feed on the conveying pipe and the buffer bin 300, and reduce the breakage rate of the pellet feed; in addition, through the treatment of the grading screen 200, the powder feed in the feed product can be separated from the qualified feed, and the screened powder feed is conveyed to the elevator through the third conveying pipe, and the elevator lifts the powder feed to the granulator for re-granulation, reducing feed waste.
[0059] In summary, the pellet feed dispensing device 10 provided by the embodiment of the present utility model includes a finished product bin 100, a grading screen 200, a buffer bin 300, and a packaging machine 400; a grading screen 200 is provided between the finished product bin 100 and the buffer bin 300 to buffer the impact force during the descent of the feed and reduce the powder content rate in the finished product packaging; the level controller provided in the buffer bin 300 is communicatively connected to the gate controller of the finished product bin 100. On the one hand, it controls the discharging speed and discharging amount of the finished feed to avoid explosion or emptying of the buffer bin 300 and maintain a normal and orderly production rhythm; on the other hand, it reduces the pressure between the finished feed in the grading screen 200 and the buffer bin 300 and reduces the powder content rate of the finished feed. The pellet feed dispensing system provided by the present utility model conveys the powder feed obtained in the grading screen 200 to the granulator through the elevator for re-granulation; this dispensing system is conducive to the recycling of materials, reduces material waste and saves production costs while doing so.
[0060] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications.
