DETAILED DESCRIPTION

[0017] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are involved in the protection scope of the utility model.

[0018] Metal aluminum is to obtain pure aluminum by electrolysis of aluminum-containing compounds, and high-temperature aluminum exists in liquid state, which is called aluminum liquid. The aluminum liquid is obtained by precipitation and cooling to obtain aluminum ingot. The temperature of the aluminum liquid changes rapidly, and the temperature of the aluminum liquid will decrease during the flow process. After the temperature decreases, the surface of the aluminum liquid is easy to oxidize and block, which affects the purity of the aluminum ingot. The outlet for the outflow of the aluminum liquid is provided in the mixing furnace or the electrolytic cell. Generally, the control valve is arranged at the outlet to automatically control the outflow of the aluminum liquid. However, the control valve is blocked by impurities in the aluminum liquid during use, which not only affects the adjustment of the flow of the aluminum liquid, but also may cause the aluminum liquid to be unable to flow out. Therefore, a practical and convenient controller for adjusting the flow of the aluminum liquid and controlling the closing of the outlet of the aluminum liquid is needed. Therefore, the utility model provides a kind of semi-automatic aluminum liquid flow controller, which will be described in detail below with reference to the accompanying drawings.

[0019] The utility model provides a kind of semi-automatic aluminum liquid flow controller, as shown in Figure 1 It includes: round table structure's plug 1, adjusting rod 2 and controller body 3;One end of the adjusting rod 2 is connected with the plug 1, and the other end of the adjusting rod 2 is connected with the controller body 3;The controller body 3 includes: box, first control valve 31, second control valve 32, connecting block 33, the connecting block 33 includes: left connecting seat 331, right bearing seat 332, outer gear shaft 333 connected with the left connecting seat 331 and the right bearing seat 332 respectively, positioning block 34 parallel with the outer gear shaft 333, the left connecting seat 331 is used to be connected with the adjusting rod 2, and the outer gear shaft 333 is used to be engaged with the valve stem of the first control valve 31;Positioning block 34 is provided on the outer gear shaft 333, and both ends of the positioning block 34 are connected with the left connecting seat 331 and the right bearing seat 332 respectively;Second control valve 32 is screwed with the positioning block 34.

[0020] As described above, the semi-automatic aluminum liquid flow controller provided by the utility model utilizes the plug 1 with round table structure to butt joint with the aluminum liquid outlet of the mixing furnace or the electrolytic furnace, realizes the control of the flow of the aluminum liquid out of the mixing furnace or the electrolytic furnace and the on-off of the aluminum liquid flow by the difference between the depth of the plug 1 into the outlet and the butt joint area of the plug 1 and the outlet, that is, the utility model realizes the semi-automatic control of the aluminum liquid, solves the problem of easy blockage of the existing control valve automatic control, and improves the practicability of the aluminum liquid flow control in the aluminum processing process.

[0021] Specifically, as shown in Figure 2 The first control valve 31 is engaged with Figure 2The second control valve 32 is used to control the vertical position of the adjusting rod 2, which is screwed with the positioning block 34. When the second control valve 32 is rotated, the greater the thrust of the valve rod to the left and right bearing seats 332, the greater the upward tilt of the end of the plug 1 of the adjusting rod 2, and the control of the aluminum liquid mainly flows out from the lower part of the plug 1. The first control valve 31 is used to control the left and right positions of the adjusting rod 2, that is, to control the depth of the plug 1 into the aluminum liquid outlet. When the first control valve 31 is rotated, the valve rod is engaged with the outer gear shaft 333, which moves left and right, because the left end of the outer gear shaft 333 is connected with the adjusting rod 2, which in turn drives the adjusting rod 2 to move left and right, that is, the depth of the plug 1 into the flow outlet controls the flow rate of the aluminum liquid in the mixing furnace or electrolytic furnace and the on-off of the aluminum liquid flow.

[0022] In actual use, the size of the aluminum liquid outlet of the mixing furnace or electrolytic furnace, and the angle or number of rotations of the first control valve 31 and the second control valve 32, can be adjusted to correspond to the actual aluminum liquid flow rate, thereby achieving precise control of the aluminum liquid flow rate.

[0023] It should be noted that the plug 1 contains a heating unit, which uses electric heating. The surface temperature of the plug 1 is close to the temperature of the aluminum liquid after power heating, which can avoid the temperature loss from the plug 1 affecting the temperature of the aluminum liquid. The heating unit can be a high-temperature-resistant PCT thermistor, which can be kept at a preset temperature and has slow heat dissipation, so as to maintain the same or similar temperature as the aluminum liquid and reduce the heat loss of the aluminum liquid.

[0024] In some embodiments, as shown in Figure 3 The semi-automatic aluminum liquid flow controller further includes a support seat 4, which includes a load-bearing plate 41 and a gas cylinder 42. The piston rod of the gas cylinder 42 is connected with the box body of the controller body 3, and the gas cylinder 42 is fixed on the load-bearing plate 41. The load-bearing plate 41 is used for detachable connection with the ground or installation plane. The gas cylinder 42 is used to adjust the installation height of the controller body 3 and fix the position of the controller body 3, so as to be compatible with the use of the device in different installation environments. The support seat 4 is mainly used to fix the stability of the device to avoid unstable plugging of the plug 1 causing aluminum liquid leakage.

[0025] In some other embodiments, a level and a scale are further included, the level is installed on the upper surface of the adjusting rod 2, and the scale corresponds to the horizontal displacement of the outer gear shaft 333. The level is used to display the levelness of the adjusting rod 2, and the contact area difference between the plug 1 and the outlet of the molten aluminum is possibly not large in the unlevel state, so that the state of the plug 1 is judged in use.

[0026] Finally, the utility model provides a kind of semi-automatic molten aluminum flow controller, comprising: plug 1 of circular table structure, adjusting rod 2 and controller body 3;One end of adjusting rod 2 is connected with plug 1, and the other end of adjusting rod 2 is connected with controller body 3;Controller body 3 includes: box, first control valve 31, second control valve 32, connecting block 33, connecting block 33 includes: left connecting seat 331, right bearing seat 332, outer gear shaft 333 connected with left connecting seat 331 and right bearing seat 332 respectively, positioning block 34 parallel with outer gear shaft 333, left connecting seat 331 is used to be connected with adjusting rod 2, and outer gear shaft 333 is used to be engaged with the valve stem of first control valve 31;Positioning block 34 is equipped on outer gear shaft 333, and both ends of positioning block 34 are connected with left connecting seat 331 and right bearing seat 332 respectively;Second control valve 32 is screwed with positioning block 34. The utility model realizes semi-automatic control molten aluminum, solves the problem that existing control valve automatic control is easy to jam, and improves the practicability of molten aluminum flow control in aluminum processing technology.
