In the splash condenser in the zinc smelting electric furnace mentioned in the paper, the graphite rotor used to lift the liquid zinc is rotatably installed on the inclined inner wall of the condensation chamber, and when the single-rotor condenser rotates in the condensation chamber, it contacts the liquid zinc by each blade when rotating, and the liquid zinc is lifted up one by one, and the lifting effect of the liquid zinc is poor.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0021] See also Figures 1 to 4 The present invention is a zinc rain condenser suitable for zinc vapor condensation process of zinc pyrometallurgy, comprising a condensing bin component 1 and a lifting component 2, wherein the condensing bin component 1 comprises a bottom bin chamber 101, a bin top cover 102 and a furnace gas inlet 103, and the lifting component 2 comprises a rotor 201, a group of sprinkling components 202 and a rotating shaft 203, by installing the bin top cover 102 above the bottom bin chamber 101 and installing the lifting component 2 at the lower end of the bin top cover 102, the sprinkling components 2 in the lifting component 2 02 is in horizontal contact with the liquid zinc level in the bottom chamber 101, so that the sprinkler assembly 202 will stir up the liquid zinc to form zinc rain when it rotates; by sleeved the rotor on the rotating shaft 203 in the lifting component 2, and the sprinkler assembly 202 is installed in a circumferential array on the outside of the rotor 201, when the liquid zinc level in the bottom chamber 101 rises, the rotor 201 rises together with the liquid zinc level, so that the depth of the sprinkler assembly 202 penetrating into the liquid zinc level remains unchanged, so that the effect of lifting the liquid zinc remains consistent.

[0022] Specifically, the silo top cover 102 covers the upper opening of the bottom silo chamber 101, the furnace gas inlet duct 103 is fixedly installed on the upper end of the silo top cover 102 and communicates with the bottom silo chamber 101, the upper end of the rotating shaft 203 passes through the plate surface of the silo top cover 102 and is fixedly connected to the output shaft of the motor, the rotor 201 is slidably sleeved on the outside of the rotating shaft 203, and a group of sprinkler components 202 are circumferentially arrayed on the side wall of the rotor 201.

[0023] Furthermore, the silo top cover 102 is a downwardly converged conical cover structure, and the rotating shaft 203 passes through the lower end conical table surface of the silo top cover 102. A motor seat 102a is fixedly installed on the upper end of the silo top cover 102. A motor is installed on the motor seat 102a and the motor is fixedly connected to the upper end of the rotating shaft 203. The motor rotates to drive the rotating shaft 203 to rotate, so that the zinc rain is lifted up by the sprinkling assembly 202 and contacts the lower cover surface of the silo top cover 102 that converges downward, so that the zinc rain falls back and contacts with the zinc-containing high-temperature furnace gas, thereby condensing the zinc vapor in the zinc-containing high-temperature furnace gas.

[0024] Furthermore, the furnace gas inlet duct 103 includes a group of vertical air inlet branches 103a and a branch pipe collecting plate 103b. A circumferential array of the group of air inlet branches 103a is fixedly installed on the lower end tube surface of the branch pipe collecting plate 103b and is connected to the branch pipe collecting plate 103b. The upper end of the branch pipe collecting plate 103b is connected to the main air inlet pipe 103b-1. The lower end of the air inlet branch pipe 103a passes through the silo top cover 102 and is connected to the bottom silo chamber 101. The high-temperature furnace gas containing zinc enters the branch pipe collecting plate 103b from the main air inlet pipe 103b-1, and enters the bottom silo chamber 101 from each air inlet branch pipe 103a.

[0025] Furthermore, the upper end of the side wall of the bottom chamber 101 is connected to a horizontal pressure relief pipe 101a, a pressure relief valve 101a-1 is installed in the pressure relief pipe 101a, an exhaust fan 101a-2 is installed in the tail end of the pressure relief pipe 101a, and a base frame support is fixedly installed at the lower end of the bottom chamber 101. When the pressure in the bottom chamber 101 is too high, the high-pressure gas will open the pressure relief valve 101a-1 and be discharged from the pressure relief pipe 101a.

[0026] Furthermore, a discharge window 101b is provided on the side wall of the bottom chamber 101, and a bin door slide rail seat 101b-1 is fixedly installed at the upper and lower ends of the discharge window 101b on the outer side wall of the bottom chamber 101, and two slide rails extending horizontally are fixed on the bin door slide rail seat 101b-1, and a bin door 101b-2 is slidably sleeved on the slide rails on the upper and lower bin door slide rail seats 101b-1. When the liquid zinc in the bottom chamber 101 needs to be released, the bin door 101b-2 is opened to release the liquid zinc from the discharge window 101b.

[0027] The operation process of this embodiment is as follows: The high-temperature furnace gas containing zinc enters the branch pipe collecting plate 103b from the main air intake pipe 103b-1, and is passed into the bottom chamber 101 from each air intake branch pipe 103a. The rotation of the motor on the motor seat 102a causes the rotating shaft 203 to rotate, thereby driving the rotor 201 and the spreading assembly 202 installed on the side wall of the rotor 201 to rotate, so that the spreading assembly 202 can lift the liquid zinc in the bottom chamber 101 to form zinc rain, and the zinc rain can contact with the high-temperature furnace gas containing zinc, so that the zinc vapor is cooled into liquid; when the liquid zinc level in the bottom chamber 101 rises, the rotor 201 gradually rises under the buoyancy of the liquid zinc, so that the penetration depth of the spreading assembly 202 and the liquid zinc remains unchanged, so that the lifting component 2 has the same lifting effect on the liquid zinc. Example 2

[0028] See also Figures 1 to 9 On the basis of Example 1, the spreading assembly 202 includes a paddle rod 202a and a group of lifting plates 202b. The paddle rod 202a is rotated by rotating the rotor 201, and then the lifting plates 202b lift the liquid zinc and sprinkle it vertically upward, thereby forming zinc rain in contact with the high-temperature furnace gas containing zinc.

[0029] Specifically, the lifting plate 202b is an L-shaped plate structure, one end of the horizontal paddle rod 202a is fixedly installed on the side wall of the rotor 201, and a side surface of the vertical plate of a group of lifting plates 202b away from the horizontal plate is fixedly sleeved on the horizontal paddle rod 202a.

[0030] Furthermore, partition plates 202b-1 are fixedly provided on both horizontal sides of the lifting plate 202b, and a channel is fixedly provided vertically on the plate surface of the vertical plate in the lifting plate 202b close to the horizontal plate, so that after the lifting plate 202b contacts the liquid zinc, it is separated by each partition plate 202b-1 and sprinkled upward, so that the lifted liquid zinc forms zinc raindrops, increasing the contact area with the zinc-containing high-temperature furnace gas, so that the zinc vapor is fully condensed.

[0031] Furthermore, the upper end of the lower horizontal plate of the lifting plate 202b, which is away from the vertical plate, is an outwardly flared arc surface, and a group of dividing bars 202b-2 are fixedly arranged in an array along the length direction at the upper end of the vertical plate of the lifting plate 202b. After the liquid zinc is lifted upward from the channel on one side of the lifting plate 202b, it is separated again by the dividing bars 202b-2, so that the lifted liquid zinc forms smaller zinc raindrops, allowing the zinc rain to contact the zinc-containing high-temperature furnace gas more fully.

[0032] Furthermore, an end cover is fixedly provided on the lower end face of the rotating shaft 203, and a group of rotating keys 203a are fixedly provided on the circumferential array of the outer side wall of the rotating shaft 203. The length direction of the rotating keys 203a on the side wall of the rotating shaft 203 is parallel to the axis of the rotating shaft 203. A group of rotating key slots 201a are vertically opened on the circumferential array of the side wall of the center hole of the rotor 201. The rotating keys 203a on the side wall of the rotating shaft 203 are respectively sleeved in the rotating key slots 201a on the rotor 201. When the liquid zinc level in the bottom chamber 101 continues to rise, the rotor 201 rises under the buoyancy of the liquid zinc, and the rotating shaft 203 continues to rotate under the action of the motor, and the rotor 201 continues to rotate through the contact between the rotating keys 203a and the rotating key slots 201a of the rotor 201.

[0033] Furthermore, the spreading assembly 202 also includes a buoy sleeve 202c, and a sleeve shaft 202a-1 is fixedly provided at one end of the transverse paddle rod 202a away from the rotor 201, and the buoy sleeve 202c is fixedly sleeved on the sleeve shaft 202a-1, and a shaft end cover 202a-2 is fixedly installed at one end of the sleeve shaft 202a-1 away from the transverse paddle rod 202a, so that the spreading assembly 202 and the rotor 201 remain floating on the surface of the liquid zinc, so that the depth of the spreading assembly 202 penetrating into the surface of the liquid zinc is the same.

[0034] The operation process of this embodiment is as follows: The motor drives the rotating shaft 203 to rotate, so that the rotor 201 drives the spreading assembly 202 to rotate. After the horizontal plate of the lifting plate 202b in the spreading assembly 202 contacts the zinc liquid surface, the liquid zinc is lifted upward along the vertical plate of the lifting plate 202b, and forms smaller zinc raindrops after being separated by the partition plate 202b-1 and the partition bar 202b-2, so that the zinc raindrops are fully in contact with the zinc-containing high-temperature furnace gas, and the zinc vapor is fully condensed; when the liquid zinc level in the bottom chamber 101 rises, the spreading assembly 202 and the rotor 201 are kept floating above the liquid zinc surface under the buoyancy of the float sleeve 202c, so that the depth of the spreading assembly 202 penetrating into the liquid zinc surface is the same, so that the effect of the spreading assembly 202 on lifting the zinc rain remains consistent.
