Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production, in particular to a quantitative feeder and a soil repair functional fertilizer production device. Background Art

[0002] Functional fertilizers are fertilizers with special uses, such as soil remediation functional fertilizers for soil heavy metal pollution remediation. When producing functional fertilizers for soil heavy metal pollution remediation, conventional compound fertilizers need to be mixed with heavy metal remediation materials. Heavy metal remediation materials are generally small particles or powders. When mixing, it is necessary to add an appropriate amount of heavy metal remediation materials according to the soil test report. At present, when producing soil remediation functional fertilizers, the heavy metal remediation materials are weighed and then manually put into the mixer. The degree of automation is low, so it is planned to carry out technical reforms on the feeding problem of heavy metal remediation materials.

[0003] At present, weighing sensors are mostly used to measure and feed materials. For example, Chinese patent document CN210729379U, published (announcement) date: 2020.06.12, discloses a mixer for fertilizer production, which discloses weighing the incoming materials through a weighing device. The weighing device includes a weighing hopper and weighing sensors arranged at the bottom of both sides of the weighing hopper. When in use, the controller needs to control the first solenoid valve to open to feed the weighing hopper. At the same time, the weighing sensor needs to transmit the weighing signal to the controller. When the weighing weight is consistent with the preset value, the first solenoid valve of the controller is closed and the second solenoid valve is opened. Although the weighing device can be used for feeding heavy metal repair materials, it is necessary to control each valve through the controller during the weighing and feeding process. It is relatively complicated in structure and control, and it is not convenient for enterprises to modify and use the equipment internally. Utility Model Content

[0029] Embodiment 1:

[0030] See also Figure 1-7A quantitative feeder comprises an outer shell 10, a quantitative device 20 and a push rod device 30. The upper end surface of the outer shell 10 is provided with a feed port 11, and the lower end surface is provided with a discharge port 12. The feed port 11 is staggered from the discharge port 12. The quantitative device 20 comprises a guide plate 21 and a quantitative cylinder 22. The upper end or both ends of the quantitative cylinder 22 are respectively provided with guide plates 21. The guide plate 21 and the quantitative cylinder 22 are connected to form a collection cavity 23. The quantitative device 20 is guided and slidably installed in the outer shell 10, and the push rod device 30 is connected to the outer wall of the quantitative cylinder 22. When the push rod device 30 is in a retracted or extended state, the collection cavity 23 is aligned with the feed port 11 or the discharge port 12, and when the collection cavity 23 is aligned with the discharge port 12, the upper guide plate 21 blocks the feed port 11.

[0031] In this embodiment, see Figure 6 When the push rod device 30 is in the retracted state, the collecting cavity 23 is aligned with the feed port 11, and the heavy metal repair material can enter the metering cylinder 22 through the feed port 11. Figure 7 When the push rod device 30 gradually extends, the push rod device 30 pushes the quantitative device 20 to move toward the discharge port 12. When the collecting cavity 23 begins to intersect with the discharge port 12, the material in the collecting cavity 23 begins to fall from the discharge port 12. When the collecting cavity 23 and the discharge port 12 are aligned, all the material in the collecting cavity 23 falls. In this process, the upper guide plate 21 blocks the feed port 11, and then the push rod device 30 begins to retract, and the quantitative device 20 returns to Figure 6 The heavy metal repair material enters the metering cylinder 22 through the feed port 11 and circulates in this way.

[0032] Preferably, the push rod device 30 is a cylinder. When in use, two air pipe interfaces on the cylinder are connected to air pipes, which are connected to a solenoid valve of a single electric control, which is connected to an air source through a pipeline, and the solenoid coil on the solenoid valve is electrically connected to a 12V power supply through a button. When the button is pressed, the solenoid valve is energized, and the piston rod of the cylinder is extended. When the button is released, the solenoid valve loses power, and the piston rod of the cylinder retracts.

[0033] The volume of the collecting chamber 23 is fixed, so the amount of feeding can be controlled by controlling the number of times the push rod device 30 is extended and retracted.

[0034] The metering device 20 is pushed and pulled to move in the outer shell 10 by the push rod device 30. When the push rod device 30 is in a retracted or extended state, the collecting cavity 23 is aligned with the feed port 11 or the discharge port 12, and when the collecting cavity 23 is aligned with the discharge port 12, the upper guide plate 21 blocks the feed port 11, so that the heavy metal repair material is quantitatively added through the metering cylinder 22 of the metering device 20. The structure and control are relatively simple, which is convenient for modification and implementation.

[0035] For further information, see Figure 3 , 4 Guide plates 21 are respectively installed at both ends of the metering cylinder 22, and a support plate 25 is installed between the two guide plates 21 at one end away from the metering cylinder 22 to improve the stability of the movement of the metering device 20. When the metering device 20 moves, the two guide plates 21 cooperate with the inner wall of the outer shell 10 from the upper and lower sides to guide.

[0036] In this embodiment, see Figure 4-7 One end of the outer shell 10 is bolted with an end plate 13, the fixed end of the push rod device 30 is connected and fixed to the end plate 13, and the telescopic end of the push rod device 30 is connected to the connecting seat 24 on the outer wall of the quantitative cylinder 22. In this way, the push rod device 30 is installed inside the outer shell 10, and the structure is compact.

[0037] Specifically, when the wall thickness of the outer shell 10 is relatively thick, the end plate 13 can be directly connected to the outer shell 10 by bolts. Figure 2 , a lug plate 15 is welded to the end of the outer shell 10, and the end plate 13 is connected to the lug plate 15 by bolts.

[0038] See also Figure 2 The outer shell 10 is provided with a connecting flange 14 at the feed inlet 11, so as to facilitate the connection between the quantitative device and the hopper 42. Specifically, a discharge round pipe is provided at the lower end of the hopper 42, and a square flange is welded at the end of the discharge round pipe, which is bolted to the connecting flange 14, and the discharge round pipe at the lower end of the hopper 42 is aligned with the feed inlet 11.

[0039] In application, the stroke of the cylinder is not necessarily equal to the center distance between the feed port 11 and the discharge port 12. That is to say, when the cylinder is in the retracted and extended positions, it may not be possible to align the metering cylinder 22 with the feed port 11 or the discharge port 12. Figure 1 , 7 , a limit baffle 16 is installed at one end of the outer shell 10 away from the push rod device 30. During installation, the stroke of the cylinder is selected to be greater than the center distance between the feed port 11 and the discharge port 12. During adjustment, it is only necessary to ensure that the metering cylinder 22 is aligned with the feed port 11 when the cylinder is retracted, and when extending, the limit baffle 16 is used to limit the extended position of the push rod device 30, so that the requirements for the push rod device 30 are reduced. During installation, the air pipe of the cylinder passes through the hole on the end plate 13.

[0040] Embodiment 2:

[0041] A soil remediation functional fertilizer production device adopts the quantitative feeder for quantitative feeding. The quantitative feeder can be applied to the process requiring quantitative feeding.

[0042] In one embodiment, see Figure 8 The soil remediation functional fertilizer production device includes a mixer 40, which has two feeding ports 41, one of which is equipped with a quantitative feeder, the feeding port 41 is connected to the discharge port 12, and a hopper 42 is installed on the feed port 11.

[0043] Specifically, the mixer 40 is an existing vertical mixer, one of the feeding ports 41 of the vertical mixer is equipped with the quantitative feeder, and the other feeding port is used to feed compound fertilizer. The compound fertilizer and the heavy metal repair material are mixed in the mixer 40 .

[0044] The working process or principle of the utility model is as follows:

[0045] See also Figure 8 During production, the push rod device 30 is first in a shortened state, see Figure 6 , the collecting cavity 23 is aligned with the feed port 11, and the heavy metal repair material is put into the hopper 42, and the heavy metal repair material enters the metering cylinder 22 through the feed port 11. When the heavy metal repair material needs to be added, the push rod device 30 is started by the button, and when the push rod device 30 gradually extends, the push rod device 30 pushes the metering device 20 to move to the side of the discharge port 12, see Figure 7 When the material collecting cavity 23 begins to intersect with the material outlet 12, the material in the material collecting cavity 23 begins to fall from the material outlet 12. When the material collecting cavity 23 is aligned with the material outlet 12, all the material in the material collecting cavity 23 falls. Figure 7 The upper guide plate 21 blocks the feed port 11, and then the push rod device 30 quickly retracts, and the quantitative device 20 returns to Figure 6 The heavy metal repair material enters the metering cylinder 22 through the feed port 11 and circulates in this way.

[0046] In addition, since the feed port 11, the material collecting cavity 23 and the discharge port 12 are connected for a moment during the process of the push rod device 30 driving the metering device 20 to retract rapidly, this moment will cause a small amount of heavy metal repair material to fall. If the heavy metal repair material falls during this process, the distance between the feed port 11 and the discharge port 12 can be increased, that is, there is a width space of the material collecting cavity 23 between the feed port 11 and the discharge port 12, so that when the push rod device 30 retracts, the material collecting cavity 23 will first enter the space between the feed port 11 and the discharge port 12, and then align with the feed port 11, thus avoiding the problem of a small amount of heavy metal repair material falling during the moment of rapid retraction of the push rod device 30.

[0047] The operation button is pressed once to put in one part by weight of heavy metal repair material, which is easy to operate. One part by weight can be 0.5 kg, 1 kg, or 2 kg, and the amount of one part by weight is determined by the volume of the collection chamber 23.
