[0034] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0035] The embodiments of this utility model relate to an environmentally friendly treatment chamber, such as... Figure 1-9 As shown, the device includes a stirring rod body 1 and a processing chamber 9. The processing chamber 9 has a discharge port 10 at its bottom, and a ball valve 8 is installed at the discharge port 10. The processing chamber 9 has a feeding port 11 at its top. A stirring rod body 1 is vertically installed inside the processing chamber 9. The outer wall of the stirring rod body 1 is surrounded by spirally upward upper stirring blades 2 and lower stirring blades 3 connected to the upper stirring blades 2. The lower stirring blades 3 extend downward and are not connected to the stirring rod body 1. The bottom surface of the lower stirring blades 3 is provided with a spherical surface 4 that matches the ball valve 8. A power device for driving the stirring rod body 1 to rotate is installed at the top of the processing chamber 9.

[0036] The outer diameter of the upper stirring blade 2 is larger than that of the lower stirring blade 3. The outer wall of the stirring rod body 1 is connected between the upper stirring blade 2 and the lower stirring blade 3 by a transition blade 7. The outer diameter of the transition blade 7 gradually increases from the lower stirring blade 3 to the upper stirring blade 2. The lower part of the processing chamber 9 is a conical structure. The lower stirring blade 3 and the transition blade 7 are both located inside the conical structure. The upper stirring blade 2 is at least partially located inside the conical structure. The transition blade 7 can optimize the material flow path and enhance the mixing uniformity.

[0037] like Figure 1 As shown, a stirring rod body 1 is vertically installed inside the processing chamber 9. A power device for controlling the rotation of the stirring rod body 1 is installed at the top of the processing chamber 9. The power device is generally a servo motor. The output shaft of the servo motor can be driven by gears, pulleys, or belts to the upper end of the stirring rod body 1. A discharge port 10 is opened at the bottom of the processing chamber 9, and a ball valve 8 is installed at the discharge port 10. The ball valve 8 is used to control the opening and closing of the discharge port 10 at the bottom of the processing chamber 9. The advantages of using the ball valve 8 are: it can be fully opened or fully closed by simply rotating the handle or actuator 90 degrees, the operation speed is much faster than that of gate valves or stop valves that require multiple rotations, the response speed is faster, and the fluid resistance and wear are minimal.

[0038] The vertical main channel hole 102 is arranged along the axial direction of the stirring rod body 1, and can be distributed as a single hole or multiple holes, for conveying high-temperature fluids.

[0039] As a single-hole design with a vertical main channel 102, a vertical main channel 102 is axially formed from top to bottom in the middle of the upper end of the stirring rod body 1. At least one transverse branch channel 103 is formed inside the blades of the upper stirring blade 2 and / or the lower stirring blade 3. One end of the transverse branch channel 103 penetrates the side wall of the upper stirring blade 2 or the lower stirring blade 3, and the other end of the transverse branch channel 103 is connected to the vertical main channel 102. The single-hole design has a lower cost and can achieve the effect of conveying high-temperature fluids. In the single-hole design, an upper interface 101 is formed at the upper end of the vertical main channel 102. The upper interface 101 is located at the upper end of the vertical main channel 102. The upper interface 101 is selected as a threaded interface or a flange interface to facilitate the connection of external fluid conveying pipes.

[0040] As a design with multiple vertical main passage holes 102, the upper end of the stirring rod body 1 has multiple vertical main passage holes 102 evenly arranged around its circumference. The upper end of each vertical main passage hole 102 is sealed. At least one transverse branch hole 103 is provided inside the upper stirring blade 2 or / and the lower stirring blade 3. One end of the transverse branch hole 103 penetrates the side wall of the upper stirring blade 2 or the lower stirring blade 3, and the other end of the transverse branch hole 103 communicates with the corresponding vertical main passage hole 102. The upper side of the body 1 is provided with lateral through holes 108 that correspond one-to-one with the vertical main channel holes 102. The upper end of the stirring rod body 1 is fitted with a rotating oil seal sleeve 104. The inner wall of the rotating oil seal sleeve 104 is provided with annular grooves 106 arranged from top to bottom in the same number as the lateral through holes 108. Each annular groove 106 is connected to its corresponding lateral through hole 108. The outer side of the rotating oil seal sleeve 104 is also provided with an external interface 109 that is connected to the annular grooves 106.

[0041] In the multi-hole design, the external interface 109 connects to the external fluid supply pipe. The high-temperature fluid enters the annular groove 106 through the external interface 109, then enters the vertical main channel 102 through the lateral through hole 108, and finally flows into the processing chamber 9 through multiple lateral branch holes 103. The rotating oil seal sleeve 104 remains stationary, while the stirring rod body 1 rotates relative to the rotating oil seal sleeve 104. The design of the annular groove 106 and the lateral through hole 108 ensures that the high-temperature fluid can smoothly enter the vertical main channel 102.

[0042] In the multi-hole scheme, the upper port of the vertical main channel 102 is sealed by a pipe plug 105, and the pipe plug 105 is threadedly connected to the inner wall of the upper port of the vertical main channel 102. The number of vertical main channels 102 is preferably two, three or four. The multi-hole scheme is relatively more expensive, but different vertical main channels 102 can transport different high-temperature fluids, and different temperatures can be set for different positions to achieve better heating effect.

[0043] In the porous design, a rotary seal 107 is installed on the inner wall of the rotary oil seal sleeve 104 on both the upper and lower sides of each annular groove 106; the rotary seal 107 avoids fluid interference between adjacent annular grooves 106 and prevents fluid from flowing out of the rotary oil seal sleeve 104.

[0044] In both the single-hole and multi-hole schemes, the vertical main road hole 102 can be a blind hole or a through hole, and the bottom of the through hole is sealed by a pipe plug 105.

[0045] The processing chamber 9 has an overall conical barrel structure. The stirring rod body 1 is the core supporting component and is a cylindrical long rod structure. The outer wall of the stirring rod body 1 is surrounded by spirally upward upper stirring blades 2 and lower stirring blades 3. The outer diameter of the upper stirring blades 2 is larger, and the outer diameter of the lower stirring blades 3 is smaller. This matches the shape of the processing chamber 9. When the stirring rod body 1 rotates clockwise, it continuously spirals up the material at the bottom of the processing chamber 9, continuously disperses and mixes it, and improves the stirring efficiency. The spherical surface 4 of the bottom of the lower stirring blades 3 matches the spherical valve core of the ball valve 8. The two can be brought close together with only a small gap, which can transport the material at the bottom of the processing chamber 9 upward as much as possible, reduce the stirring dead zone and ensure the uniformity of stirring. When high-temperature fluid is required, the high-temperature fluid enters the vertical main channel hole 102 through the upper interface 101, and then is evenly sprayed out from the side wall of the upper stirring blades 2 or the lower stirring blades 3 through the horizontal branch channel hole 103 to achieve high-temperature treatment of the material.

[0046] As an installation scheme for the main body 1 of the stirring rod, such as Figure 1 and Figure 9 As shown, a bearing seat 13 is installed on the top of the processing chamber 9. A bushing 22 is rotatably installed inside the bearing seat 13. A tapered roller bearing 14 and a one-way thrust bearing 20 are sequentially fitted between the inner wall of the bearing seat 13 and the bushing 22 from bottom to top. The combination of the tapered roller bearing 14 and the one-way thrust bearing 20 enables the bushing 22 to rotate freely and bear axial and radial loads. The upper end of the stirring rod body 1 passes through the bushing 22 from bottom to top. A step 5 is arranged on the upper part of the stirring rod body 1. Two split positioning rings 18 are symmetrically arranged between the step 5 and the upper end of the bushing 22. The split positioning rings 18 are C-shaped. The two split positioning rings 18 are spliced ​​to form a ring to limit the stirring rod body 1. The step 5 is fastened to the two split positioning rings 18, which is easy to install. The inner diameter of the ring is smaller than the outer diameter of the step 5, and the outer diameter of the ring is larger than the inner diameter of the bushing 22. The split positioning rings 18 and the bushing 22 are fixed with fasteners 23.

[0047] A locking nut 16 is screwed onto the outer side of the bushing 22. The locking nut 16 is located below the tapered roller bearing 14. A retaining washer 15 is installed between the locking nut 16 and the tapered roller bearing 14. The locking nut 16 is used to adjust the preload of the tapered roller bearing 14.

[0048] The lower port of the bearing housing 13 is sealed by the lower cover plate 17. The tapered roller bearing 14, the one-way thrust bearing 20, the locking washer 15, and the locking nut 16 are all installed through the lower port of the bearing housing 13, making installation convenient. The lower cover plate 17 and the bearing housing 13 are fixed together with fasteners. A lower skeleton oil seal 21 is provided between the lower cover plate 17 and the bushing 22, and an upper skeleton oil seal 19 is provided between the upper port of the bearing housing 13 and the bushing 22. The upper skeleton oil seal 19 and the lower skeleton oil seal 21 are provided to ensure the sealing performance during long-term operation and reduce the maintenance frequency.

[0049] A keyway groove 6 is provided on the side of the upper end of the stirring rod body 1. The keyway groove 6 is located above the step 5. The step 5 is provided to support and limit the stirring rod body 1. The keyway groove 6 is provided to facilitate the installation of transmission components, which can be gears or pulleys.

[0050] The ball valve 8 is an electric ball valve, which is easy to operate.

[0051] The feeding port 11 is inclined upward and located on the side of the upper part of the processing chamber 9. The upper opening of the feeding port 11 is provided with a cover 12 that can be opened and closed. The upward inclination of the feeding port 11 facilitates the addition of materials and reduces dust overflow.
