[0027] Please refer to Figure 1 and Figure 2 A material pipe mechanism provided by the embodiment of the present application, comprising a material box 1, a driving member 2, a proximity switch 3 and a limiting block 4.

[0028] Specifically, the shape of the material box 1 is a square structure, and the bottom of the material box 1 is formed with a constant volume cavity structure, which can hold a constant volume of material, realize constant volume feeding, and the bottom of the constant volume cavity structure is provided with a discharge port 11, and the discharge port 11 is provided with a sealing element 12, the shape of the sealing element 12 is the same as that of the discharge port 11, and the sealing element 12 can move up and down or rotate relative to the discharge port 11, so that the sealing element 12 can open or close the discharge port 11.

[0029] The driving member 2 can be installed on the crown block, and the driving member 2 can also be drivingly connected with the material box 1, and the driving member 2 drives the material box 1 to ascend or descend in the vertical direction, more specifically, the driving member 2 is connected with the material box 1 by using appropriate connecting devices such as chains, steel cables or transmission belts, etc., to ensure that the driving member 2 is firmly and reliably connected with the material box 1, and can withstand the tension of the material box 1 during ascending and descending.

[0030] The proximity switch 3 can be arranged at the discharge port 11, preferably, the proximity switch 3 is arranged on the side wall forming the discharge port 11, and the proximity switch 3 is arranged along the axis of the discharge port 11, so that the trigger point of the proximity switch 3 is arranged in the direction of the axis of the discharge port 11, and the limit block 4 can be arranged on the sealing element 12, and the limit block 4 is arranged opposite to the proximity switch 3, so that the limit block 4 is arranged opposite to the trigger point of the proximity switch 3.

[0031] When the sealing element 12 opens the discharge port 11, the sealing element 12 drives the limit block 4 away from the proximity switch 3, so that the proximity switch 3 is in an open state, thereby the driving member 2 cannot be started, that is, when the discharge port 11 is opened, the driving member 2 cannot drive the material box 1 to ascend, when the sealing element 12 closes the discharge port 11, the sealing element 12 drives the limit block 4 close to the proximity switch 3, so that the proximity switch 3 is in a closed state, thereby the driving member 2 can be started, that is, when the discharge port 11 is closed, the driving member 2 can drive the material box 1 to ascend.

[0032] Therefore, the operator must ensure that the sealing element 12 closes the discharge port 11 before starting the driving member 2 to make the material box 1 ascend during operation, which enhances the safety of operation, avoids material leakage or equipment damage caused by misoperation, and effectively prevents the material box 1 from accidentally ascending when the discharge port 11 is opened, resulting in dust caused by sudden falling of the material.

[0033] Please refer to Figure 1 and Figure 2 In some embodiments, the proximity switch 3 can be an inductive proximity switch 3, and the limit block 4 is a metal block. The inductive proximity switch 3 is a non-contact sensor that uses electromagnetic induction principle to detect the approach of metal objects. When the limit block 4 enters the sensing range of the proximity switch 3, it will change the magnetic field inside the switch, thereby triggering the action of the switch.

[0034] Specifically, when the sealing piece 12 closes the discharge port 11, the metal limit block 4 will move into the sensing range of the inductive proximity switch 3, at this time, the inductive proximity switch 3 will detect the presence of the metal limit block 4 and output a signal to enable the driving element 2; when the sealing piece 12 opens the discharge port 11, the metal limit block 4 will move out of the sensing range of the inductive proximity switch 3, and the inductive proximity switch 3 will be disconnected, so that the driving element 2 cannot be started. In this way, the precise control of the start of the driving element 2 is realized, and the response speed is fast, the detection distance is adjustable, and the anti-interference ability is strong.

[0035] In some other embodiments, the proximity switch 3 can be a capacitive proximity switch 3, and the limit block 4 can be a non-metallic object. The capacitive proximity switch 3 detects the proximity of the object by measuring the change in capacitance caused by the object. Unlike the inductive proximity switch 3, the capacitive proximity switch 3 also has good detection effect on non-metallic objects, especially plastic, wood, ceramic, etc.

[0036] Specifically, when the non-metallic limit block 4 approaches the capacitive proximity switch 3, the capacitance inside the capacitive proximity switch 3 will change, thereby triggering the switch action; when the limit block 4 moves away from the switch, the capacitance returns to the original state, and the switch is disconnected. In this way, the precise control of the start and stop of the driving element 2 can also be realized. The use of the capacitive proximity switch 3 can adapt to more types of limit block 4 materials, and the non-metallic limit block 4 usually has a lower cost, which helps to reduce the overall system manufacturing cost.

[0037] Please refer to Figure 1 and Figure 2 In some embodiments, the tube mechanism can further include a relay, and the output end of the relay can be electrically connected with the power supply end of the driving element 2, and the proximity switch 3 can be connected in series with the coil of the relay. Such a connection mode can realize the automatic control of the driving element 2.

[0038] Specifically, when the proximity switch 3 detects the object and triggers, it will close the circuit, so that the coil of the relay obtains current and generates a magnetic field, thereby causing the contacts of the relay to close or open. The contacts of the relay are electrically connected with the power supply end of the driving element 2, so when the state of the contacts changes, the power supply on-off state of the driving element 2 will also change accordingly, thereby controlling the start or stop of the driving element 2.

[0039] Please refer to Figure 1 In some embodiments, the driving element 2 can include a base 21 and a first motor 22 arranged on the base 21.

[0040] Specifically, the base 21 is in a cylindrical structure, and a transmission space is formed in the base 21, the first motor 22 can be fixed on the base 21, and the output end of the first motor 22 can be located in the interior of the base 21, i.e., in the transmission space, and the base 21 is provided with a driving hole, the output end of the first motor 22 is connected with a transmission member and a steel cable, the steel cable passes through the driving hole and extends to be connected with the material box 1, so that the output end of the first motor 22 is drivingly connected with the material box 1 through the steel cable, and the material box 1 can be driven to ascend or descend by the first motor 22.

[0041] Meanwhile, the proximity switch 3 is connected with the first motor 22 in series through the wire 6, so that the first motor 22 can be controlled to start or stop by the proximity switch 3, specifically, when the limiting block 4 approaches the proximity switch 3, the proximity switch 3 senses the existence of the object and outputs a signal, the signal is transmitted to the first motor 22 through the wire 6, so as to control the starting of the motor, and when the object is away from the proximity switch 3, the switch also outputs a signal to make the motor stop. In this way, the proximity switch 3 can control the running state of the motor in real time according to the position of the limiting block 4.

[0042] Please refer to Figure 1 In some embodiments, the driving member 2 can further include a walking structure 23, which can be installed on the top of the base 21 and can be installed on the main beam of the crown block, so that the walking structure 23 can move along the main beam of the crown block, thereby the walking structure 23 can drive the first motor 22 to move along the main beam, and the main beam of the crown block is usually arranged in the horizontal direction, i.e., the walking structure 23 can drive the first motor 22 to move in the horizontal direction, so as to adjust the position of the material box 1 and facilitate the material box 1 to feed the aluminum electrolysis cell.

[0043] Please refer to Figure 1 In some embodiments, the walking structure 23 can include a walking support 231 and a second motor 232.

[0044] Specifically, the walking support 231 can be fixed on the top of the base 21, and a walking cavity can be formed on the top of the walking support 231, a plurality of rollers 2311 are arranged in the walking cavity, the plurality of rollers 2311 can cooperate with the track on the main beam of the crown block, so that the rollers 2311 can move along the track, and the second motor 232 can be arranged on the walking support 231 and drivingly connected with the rollers 2311, so that the second motor 232 can drive the rollers 2311 to move along one end of the track, thereby driving the base 21 to move along the track.

[0045] Please refer to Figure 1 and Figure 3In some embodiments, the tube mechanism can further include a wire reel 5, which can be arranged on the side wall of the material box 1, and a wire 6 can be arranged on the wire reel 5. The main function of the wire reel 5 is to wind and release the wire 6, and one end of the wire 6 can be electrically connected with the driving part 2, and the other end can be electrically connected with the proximity switch 3.

[0046] Specifically, when the material box 1 rises or falls, the wire reel 5 can automatically release or wind the wire 6, ensuring that the wire 6 always maintains an appropriate length, avoiding problems caused by being too long or too short, and preventing the wire 6 from being wound or damaged during the movement of the material box 1.

[0047] Please refer to Figure 1 and Figure 3 In some embodiments, the wire reel 5 can include a flange 51, a housing 52, and a winding part 53.

When the material box 1 moves, the winding part 53 can automatically wind or release according to the change of the tension of the wire 6, ensuring that the wire 6 always maintains an appropriate length and tension.

[0049] Please refer to Figure 3 In some embodiments, the wire reel 5 can further include a limiting part 54, which is a thin round rod structure, and the housing 52 can be provided with a limiting hole 521, and the limiting part 54 can be inserted into the limiting hole 521 and connected with the winding part 53, thereby achieving the limiting effect of the winding part 53.
