DETAILED DESCRIPTION
[0026] The utility model provides an intermittent feeding device and a ferric nitrate production device. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0027] See also Figure 1-3 The utility model provides an intermittent feeding device, which includes a feeding mechanism, a vibrating feeding mechanism, an intermittent unloading mechanism and a control mechanism. Among them:
[0028] Feeding mechanism: It includes a conveyor belt 1 and a hopper 2. The conveyor belt 1 is used to continuously convey materials to the hopper 2. The hopper 2 is located below the output end of the conveyor belt 1 and is used to receive and temporarily store the materials output by the conveyor belt 1. In the specific implementation process, the materials output by the conveyor belt 1 just fall into the hopper 2. Through the temporary storage of the hopper 2, the materials can be prevented from spilling out, and intermittent feeding is convenient.
[0029] A vibrating feeding mechanism comprises a feeding trough 3 arranged below the hopper 2 and a vibrating motor 4 for driving the feeding trough 3 to vibrate; the feeding trough 3 is arranged at an angle, with its feeding end located below the hopper 2 and a notch provided at the other end, which is located above the lower barrel 5, and the position height of the feeding end is higher than the notch end, so when the feeding trough 3 vibrates, the material will move from the feeding end to the notch end; the vibrating motor 4 is arranged at the bottom of the feeding trough 3 near the feeding end, and through the action of the vibrating motor 4, the feeding trough 3 can vibrate intermittently, and through vibration, the material can be transported from the bottom of the hopper 2 to the notch of the feeding trough 3, and fall into the lower barrel 5 through the notch.
[0030] The intermittent unloading mechanism includes an unloading barrel 5 connected to the reactor 8, a swing plate 6 swingably arranged in the unloading barrel 5, and a counterweight block 7 connected to the top of the swing plate 6; the unloading barrel 5 is a barrel with a rectangular cross-section, and its upper barrel opening faces the notch of the feed trough 3, and its lower barrel opening is connected to the reactor 8; a support seat 9 is arranged on the side wall of the unloading barrel 5, and the swing plate 6 is hinged to the support seat 9, and under the action of the counterweight block 7, it is tilted and arranged in the unloading barrel 5 to form a baffle, which can block the unloading barrel 5 to prevent the material from falling directly into the reactor. When in use, Figure 1When no material falls, the swing plate 6 tilts under the action of the counterweight 7, and its bottom end abuts against the side wall of the discharge barrel 5, thereby blocking the discharge barrel 5; when material falls, the material falls on the swing plate 6. When the weight of the falling material is less than the weight of the counterweight 7, the swing plate 6 does not swing down. When the falling material is greater than the weight of the counterweight 7, the bottom end of the swing plate 6 swings down. Figure 2 , Figure 3 As shown, the lower barrel port is connected, and the material will fall into the reaction kettle 8.
[0031] The control mechanism includes a controller (not shown in the attached drawings), an infrared sensor 10 and a baffle 11. The controller is electrically connected to the infrared sensor 10 and the vibration motor 4, respectively, and can receive the signal transmitted by the infrared sensor 10, and perform timing according to the signal, and can control the on and off of the vibration motor 4 according to the received signal and the set interval time; the baffle 11 is set on the top of the swing plate 6 and faces the infrared sensor 10. When the swing plate 6 does not swing down, the infrared rays emitted by the infrared sensor 10 just hit the baffle 11 and return to the infrared sensor 10, as shown in FIG. Figure 1 As shown, when the swing plate 6 swings down, the baffle 11 will swing along with it. Figure 2 , Figure 3 As shown, the infrared sensor 10 is misaligned, so that the infrared sensor 10 cannot receive infrared rays, and it will feed back corresponding signals to the controller so that the controller can perform timing and control the vibration motor 4.
[0032] During operation, the conveyor belt 1 conveys the material to the hopper 2, and the material falls from the hopper 2 into the feeding trough 3. When the set interval time has passed, the controller starts the vibration motor 4 to vibrate the feeding trough 3, and vibrates the material falling from the hopper 2 into the lower barrel 5. When the weight of the material in the lower barrel 5 is greater than the weight of the counterweight 7, the swing plate 6 swings down under the action of gravity, so that the material enters the reactor 8 through the lower outlet of the lower barrel 5, completing one feeding; when the swing plate 6 swings, the baffle 11 swings accordingly and is misaligned with the infrared sensor 10, causing the infrared sensor 10 to be unable to receive infrared rays, which forms a corresponding The signal is sent to the controller, and the controller stops the vibration motor 4 and starts timing at the same time; when the timing time of the controller reaches the set interval time, the controller restarts the vibration motor 4 and continues to vibrate the feeding trough 3 to transport the material to the discharge barrel 5. When the amount of material is greater than the weight of the counterweight 7, the swing plate 6 swings down again, and the material falls into the reactor 8. When the swing plate 6 swings, the baffle 11 swings synchronously, and the baffle 11 is misaligned with the infrared sensor 10. The infrared sensor 10 forms a feedback signal to the controller, and the controller stops the vibration motor 4 again and starts timing at the same time. This cycle is repeated to achieve intermittent feeding.
[0033] In this embodiment, by setting up an intermittent feeding mechanism and a control mechanism, and utilizing the swing plate 6 and the counterweight block 7 provided in the intermittent feeding mechanism, intermittent quantitative feeding can be achieved, and the weight of the feed can be adjusted by the counterweight block 7; utilizing the provided infrared sensor 10 and the baffle 11, the controller can conveniently control the motor to achieve timed intermittent feeding. Therefore, the intermittent feeding device can achieve timed quantitative automatic intermittent feeding, which can reduce labor costs and improve production efficiency.
[0034] During the specific implementation process, the weight of the counterweight block 7 can be set according to the amount of single feed. The larger the single feed amount, the heavier the counterweight block 7. The time of intermittent feeding can be set by the controller, and the specific duration is set according to the volume and reaction speed of the reactor 8.
[0035] In a preferred embodiment, Figure 1 , Figure 2 As shown, the top of the swing plate 6 is provided with a connecting rod 12, which can be a rod with a circular or square cross section. The counterweight 7 is a cylindrical shape with a perforation in the center. The perforation is adapted to the shape and size of the connecting rod 12. The counterweight 7 can be inserted into the connecting rod 12 through the perforation. The counterweight 7 is provided with a threaded hole that penetrates along its radial direction. The threaded hole is connected with a bolt. The locking bolt can make the counterweight 7 firmly connected to the connecting rod 12. When it is necessary to adjust the feeding amount of a single material, the weight of the counterweight 7 can be adjusted, and the position of the counterweight 7 on the connecting rod 12 can also be adjusted. When the counterweight 7 is closer to the top of the swing plate 6, the single feeding amount will be less, and vice versa. In the specific implementation process, the position or weight of the counterweight 7 can be adjusted according to actual needs.
[0036] In another preferred embodiment, Figure 4 As shown, the configuration block is connected to the top of the swing plate 6 through a connecting line 13, and a fixed pulley 14 is provided on the outer wall of the discharge barrel 5, one end of the connecting line 13 is connected to the top of the swing plate 6, and the other end passes around the fixed pulley 14 and is connected to the counterweight 7. When the weight of the material carried by the swing plate 6 is greater than the weight of the counterweight 7, the bottom end of the swing plate 6 swings down and the top end of the swing plate 6 swings up, and the connecting line 13 pulls the counterweight 7 to move upward. Under the action of the fixed pulley 14, the counterweight 7 can move up and down very smoothly.
[0037] In a preferred embodiment, Figure 1 , Figure 2 , Figure 4 As shown, in order to prevent the vibration motor 4 from causing the feed trough 3 to vibrate too much, one or more shock-absorbing springs 15 are provided below the feed trough 3. Through the buffering effect of the shock-absorbing springs 15, the vibration amplitude of the feed trough 3 can be reduced and made smoother, but the vibration frequency remains unchanged, thereby better controlling the feeding amount.
[0038] The second aspect of the utility model also provides a ferric nitrate production device, which includes a reactor 8 and the intermittent feeding device as described above. The lower barrel 5 of the intermittent feeding device is connected to the reactor 8. Through the intermittent feeding device, iron blocks or iron powder can be added to the reactor 8 in a timely and quantitative manner, which can avoid excessively intense reactions and ensure safer production. At the same time, it can reduce labor costs and improve production efficiency.
