[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please see Figure 1-4 The present invention provides the following technical solution: a precision feeding device for producing iron phosphate, comprising a weighing component 1, a feed inlet 3 fixedly installed above the weighing component 1, an agitator 5 installed at the lower position of the weighing component 1, a discharge port 6 provided below the weighing component 1, a control panel 7 fixedly installed on one side of the weighing component 1, a filter air supply device 2 provided outside the feed inlet 3, and the weighing component 1 and the discharge port 6 connected by a position adjustment device 4; The air supply device 2 includes a first electric telescopic rod 21. The first electric telescopic rod 21 is fixedly installed on the side of the weighing component 1 away from the control panel 7. A movable plate 22 is fixedly installed on the side of the first electric telescopic rod 21 away from the weighing component 1. A connecting frame 24 is fixedly installed on one side of the movable plate 22 and above the feed inlet 3. A filter screen 25 is fixedly installed on the inner side of the connecting frame 24. An air supply component 23 is provided above the connecting frame 24.

[0018] Specifically, the height of the top surface of the feed inlet 3 is equal to the height of the bottom surface of the connecting frame 24.

[0019] By adopting the above technical solution, the device can ensure that the outer top surface of the feed inlet 3 and the outer bottom surface of the connecting frame 24 fit together without gaps, thereby ensuring sealing and preventing raw material leakage.

[0020] Specifically, the air supply assembly 23 includes a movable cover 234. The movable cover 234 is provided above the connecting frame 24. The movable cover 234 is connected to the movable plate 22 through a second electric telescopic rod 231. A fan 233 is fixedly installed above the movable cover 234. A partition net 232 is fixedly installed above the air inlet end of the fan 233.

[0021] By adopting the above technical solution, workers can use the combination of structures such as the fan 233 and the movable cover 234 to help discharge the residual raw materials inside when needed, thereby reducing the waste of raw materials.

[0022] Specifically, the height of the top surface of the connecting frame 24 is equal to the height of the bottom surface of the movable cover 234.

[0023] By adopting the above technical solution, the device can ensure that the outer top surface of the connecting frame 24 and the outer bottom surface of the movable cover 234 fit together without gaps, thereby ensuring airtightness and preventing leakage of the transported air.

[0024] In this embodiment, when precise feeding is required during ferric phosphate production, the operator fixes the device to the ferric phosphate production equipment. If filtration of the raw material is needed, the operator can activate the first electric telescopic rod 21 in the filtration air supply device 2, thereby moving the moving plate 22 and its connecting frame 24 and other structures until the filter screen 25 moves above the feed inlet 3. Then, the raw material is poured into the connecting frame 24, the filter screen 25 filters the raw material, and the filtered raw material falls into the weighing assembly 1. The operator controls the weighing assembly through the control panel 7. 1. Then, a suitable amount of raw material continues to descend and is agitated by the stirring component 5. The raw material is then discharged through the discharge port 6 to the iron phosphate production equipment for use. When some raw material remains inside the device, the operator starts the second electric telescopic rod 231 in the air conveying component 23, thereby moving the moving cover 234 above the filter screen 25. Then, the blower 233 is started, and the blower 233 sends the air filtered by the partition screen 232 into the connecting frame 24. Then, the airflow passes through the feed port 3 and the weighing component 1, and finally carries the remaining raw material out of the discharge port 6.

[0025] Example 2: The difference between this embodiment and embodiment 1 is that the position adjustment device 4 includes a lead screw 41. The lead screw 41 is mounted on one side of the weighing component 1 and below the control panel 7 via a bearing. A movable frame 43 is mounted on the outside of the lead screw 41 and outside the weighing component 1 via a thread. The movable frame 43 is connected to the discharge port 6 via a conveying pipe 44.

[0026] By adopting the above technical solution, the staff can adjust the position of the discharge port 6 by means of the cooperation of the lead screw 41 and the moving frame 43 when needed, so as to better meet the production needs under different circumstances.

[0027] Specifically, the height of the outer bottom surface of the weighing component 1 is equal to the height of the inner bottom surface of the moving frame 43.

[0028] By adopting the above technical solution, it is ensured that the outer bottom surface of the weighing component 1 and the inner bottom surface of the moving frame 43 are tightly fitted, thereby ensuring the sealing performance and preventing the leakage of raw materials.

[0029] Specifically, a friction rubber ring 42 is fixedly installed on the outer side of the end of the lead screw 41 near the weighing assembly 1.

[0030] By adopting the above technical solution, the friction rubber ring 42 can increase the frictional resistance when the lead screw 41 rotates, effectively preventing the lead screw 41 from rotating unexpectedly, thereby ensuring the stability of the device operation.

[0031] In this embodiment, when the position of the discharge port 6 needs to be adjusted, the operator rotates the lead screw 41 in the position adjustment device 4. The lead screw 41 is threadedly connected to the moving frame 43, and the inner side of the moving frame 43 is in contact with the outer side of the weighing component 1. Therefore, the lead screw 41 drives the moving frame 43 and the conveying pipe 44 below it to move until the discharge port 6 moves to the required position, thereby better meeting the production needs under different conditions. The friction rubber ring 42 plays a role in enhancing frictional resistance and preventing accidental rotation.

[0032] The structure and principle of the weighing assembly 1 (comprising a mixing tank, chute, induction transmission block, slide plate, buffer rubber block, baffle strip, pull rod, sprocket, warning light, distance sensor, bearing plate, permanent magnet, electromagnet, support plate, guide plate, and baffle plate), the feed inlet 3, the agitation assembly 5 (comprising a bearing, agitating rod, agitating blade, and transmission box), the discharge port 6, and the control panel 7 in this utility model have been disclosed in the fine chemical raw material self-precision feeding device disclosed in announcement number CN207342654U. Its working principle is that when the material falls onto the bearing plate... When the mass on the plate exceeds the attraction force between the two magnets, the bearing plate tilts to the right via the hinge to discharge the material, while the left end rises, reducing the sensing distance of the distance sensor. This causes the induction transmission blocks to move in opposite directions, driving the telescopic plate to close the feed inlet, thus preventing the material from falling further and completing the self-precise feeding process. When the material falls, the bearing plate returns to a horizontal state under the attraction force, increasing the sensing distance of the distance sensor. This controls the induction transmission blocks to move in the opposite direction, causing the telescopic plate to retract into the movable cavity, opening the feed inlet and allowing the material to continue falling. This process is repeated.

[0033] The working principle and usage process of this utility model are as follows: When precise feeding is required in the production of ferric phosphate, the operator fixes the device to the ferric phosphate production equipment. If filtration of the raw material is required, the operator can activate the first electric telescopic rod 21 in the filtration air supply device 2, thereby moving the moving plate 22 and its connecting frame 24 and other structures until the filter screen 25 moves above the feed inlet 3. Then, the raw material is poured into the connecting frame 24, and the filter screen 25 filters the raw material. The filtered raw material then falls into the weighing component 1. The operator controls the weighing component 1 through the control panel 7, and then the appropriate amount of raw material continues to fall. It is stirred by the stirring component 5, and then the raw material is discharged through the discharge port 6 into the ferric phosphate production equipment for use. When some raw material remains inside the device, the operator activates the... The second electric telescopic rod 231 in the air conveying assembly 23 drives the movable cover 234 to move above the filter screen 25, and then the fan 233 is started. The fan 233 sends the air filtered by the screen 232 into the connecting frame 24. Then the airflow passes through the feed port 3 and the weighing assembly 1, and finally discharges from the discharge port 6 with the residual raw materials. When it is necessary to adjust the position of the discharge port 6, the operator rotates the screw 41 in the position adjustment device 4. The screw 41 is threadedly connected to the movable frame 43, and the inner side of the movable frame 43 is in contact with the outer side of the weighing assembly 1. Therefore, the screw 41 drives the movable frame 43 and the conveying pipe 44 below it to move until the discharge port 6 moves to the required position, so as to better meet the production needs under different conditions. The friction rubber ring 42 plays a role in increasing friction resistance and preventing accidental rotation.
