Description

Technical Field

[0001] This utility model relates to the field of sulfur slurry mixing technology, specifically to a sulfur slurry mixing device for acid production sulfur slurry storage tank that reduces stirring time. Background Technology

[0002] The sulfur foam generated during coking desulfurization regeneration is separated into sulfur slurry by centrifugation in the acid production process and stored in a sulfur slurry storage tank. The sulfur slurry in the storage tank is then pumped to the sulfur melting tower for sulfur melting. The high-temperature clear liquid flows under pressure into the concentration tower to concentrate the ammonium thiocyanate, ammonium sulfate, and ammonium thiosulfate salts in the sulfur slurry. The concentration is reduced to a density of about 1.25-1.27 g / L and then pumped to the concentrated salt tank (jacket). The concentrated salt is then pumped to the incinerator for combustion to produce process gas containing sulfur dioxide, thus realizing the utilization of the sulfur foam generated during coking desulfurization regeneration. However, after a period of storage, the sulfur slurry in the storage tank is prone to sedimentation and stratification, resulting in uneven composition of the sulfur slurry. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a sulfur slurry mixing device for acid slurry storage tanks is provided to reduce stirring time, thereby solving the problem that sulfur slurry in the storage tank is prone to sedimentation and stratification after being stored for a period of time, resulting in uneven composition of the sulfur slurry.

[0004] To achieve the above objectives, a sulfur slurry mixing device for acid production slurry storage tanks is provided, comprising: a trough-shaped mixing body, wherein a sealing top plate is fixedly connected to the upper end of the trough-shaped mixing body by fastening bolts.

[0005] The trough-shaped mixer body is provided with a conical slurry storage chamber on its inner side. A slurry guide pipe is connected to the lower right side of the trough-shaped mixer body. The slurry guide pipe is connected to a slurry return pipe through a sulfur slurry conveying pump. The side end of the slurry return pipe is connected to the conical slurry storage chamber through a slurry return port. A stirring rod is provided in the middle of the conical slurry storage chamber. Agitators are installed at equal intervals on the surface of the stirring rod. A stirring motor is connected to the upper end of the stirring rod through a coupling.

[0006] Furthermore, a feed inlet is provided on the left end face of the trough-shaped mixer body, and a discharge outlet is provided on the lower end face of the trough-shaped mixer body.

[0007] Furthermore, a manual valve is installed on the surface of the discharge pipe; and the slurry guide pipe is connected at the upper right end of the manual valve, and an electric valve is installed on the surface of the slurry guide pipe.

[0008] Furthermore, a support frame is welded to the outer end of the trough-shaped mixer body, and a controller is fixed to the front end face of the support frame.

[0009] Furthermore, a sulfur slurry delivery pump is fixedly installed on the right side of the support frame, and the controller is electrically connected to the sulfur slurry delivery pump.

[0010] Furthermore, a fixing plate is welded to the upper surface of the sealing top plate, and a stirring motor is installed at the upper end of the sealing top plate.

[0011] Furthermore, a return slurry port is provided at the conical wall of the conical slurry storage chamber; and the return slurry pipe is tangentially distributed to the conical wall of the conical slurry storage chamber.

[0012] The beneficial effects of this utility model are as follows: The sulfur slurry mixing device for reducing stirring time utilizes the guide pipe and return pipe connected at the bottom end and the tangent of the cone surface of the conical cavity of the tank-type mixer. The sulfur slurry at the bottom of the conical storage cavity is transported upward to the tangent of the cone surface of the conical storage cavity by the sulfur slurry delivery pump. This causes the agitator to rotate and drive the returned sulfur slurry to form a strong vortex motion along the conical wall, which facilitates rapid mixing and thorough mixing of the precipitated and stratified sulfur slurry in the sulfur slurry mixing device. This enhances the mixing and stirring force of the sulfur slurry mixing device, improves the mixing efficiency of the sulfur slurry mixing device, and effectively shortens the stirring time of the sulfur slurry mixing device.

[0017] Reference Figures 1 to 3 As shown, this utility model provides a sulfur slurry mixing device for reducing stirring time in an acid-making sulfur slurry storage tank, comprising: a trough-shaped mixer body 1, with a sealing top plate 2 fixedly connected to the upper end of the trough-shaped mixer body 1 by fastening bolts 21.

[0018] A conical slurry storage chamber 14 is provided inside the trough-type mixer body 1. A slurry guide pipe 4 is connected to the lower right side of the trough-type mixer body 1. The slurry guide pipe 4 is connected to a return slurry pipe 41 through a sulfur slurry conveying pump 42. The side end of the return slurry pipe 41 is connected to the conical slurry storage chamber 14 through a return slurry port 15. A stirring rod 51 is provided in the middle of the conical slurry storage chamber 14. Agitators 5 are installed at equal intervals on the surface of the stirring rod 51. A stirring motor 52 is connected to the upper end of the stirring rod 51 through a coupling 53.

[0019] Before the sulfur slurry in the trough mixer 1 is output for use, the stirring motor 52 and the sulfur slurry delivery pump 42 are turned on. The stirring motor 52 drives the agitator 5 to rotate and stir the sulfur slurry in the conical storage chamber 14. At the same time, the sulfur slurry delivery pump 42 pressurizes and delivers the precipitated and stratified sulfur slurry at the bottom of the conical storage chamber 14 to the return slurry pipe 41 through the slurry guide pipe 4. The return slurry pipe 41 discharges the sulfur slurry at a certain pressure from the cut surface of the conical storage chamber 14. The sulfur slurry discharged from the conical cut surface forms a strong vortex motion under the rotation of the agitator 5. The vortex motion efficiently promotes the rapid and uniform mixing of the stratified components of the sulfur slurry, which facilitates the mixing and stirring of the sulfur slurry mixing device, improves the mixing efficiency of the sulfur slurry mixing device, and effectively shortens the mixing time of the sulfur slurry mixing device.

[0020] In this embodiment, a feed inlet 11 is provided on the left end face of the trough mixer body 1, and a discharge outlet 12 is provided on the lower end face of the trough mixer body 1.

[0021] In a preferred embodiment, the feed port 11 facilitates the delivery of sulfur slurry generated by sulfur foam centrifugation to the trough mixer body 1 for temporary storage, which is then discharged when needed. The manual valve 13 facilitates the control of sulfur slurry discharge from the trough mixer body 1. The electric valve 43 facilitates the control of the flow of sulfur slurry inside the trough mixer body 1 into the slurry guide pipe 4.

[0022] In this embodiment, a support frame 3 is welded to the outer end of the trough-shaped mixer body 1, and a controller 31 is fixed to the front end of the support frame 3. A sulfur slurry delivery pump 42 is fixedly installed on the right side of the support frame 3, and the controller 31 is electrically connected to the sulfur slurry delivery pump 42. A fixing plate 22 is welded to the upper surface of the sealing top plate 2, and a stirring motor 52 is installed at the upper end of the sealing top plate 2.

[0023] As a preferred embodiment, the support frame 3 facilitates stable support of the trough-type mixer body 1. The controller 31 is used to control the start of the sulfur slurry delivery pump 42 and the stirring motor 52, so that while the stirrer 5 is stirring, the sulfur slurry delivery pump 42 delivers the sulfur slurry at the bottom of the conical storage chamber 14 to the tangential part of the conical wall, thereby increasing the speed of full mixing of the sulfur slurry in the trough-type mixer body 1.

[0024] In this embodiment, a return slurry port 15 is provided at the conical wall of the conical slurry storage chamber 14; and the return slurry pipe 41 is tangentially distributed to the conical wall of the conical slurry storage chamber 14.

[0025] As a preferred embodiment, the return port 15 is located on the conical wall of the conical storage cavity 14, so that the sulfur slurry output by the return pipe 41 enters the conical storage cavity 14 in a tangential state through the return port 15, thereby forming a strong vortex motion, which promotes the rapid and uniform mixing of the layered components of the sulfur slurry, which facilitates the strengthening of the mixing and stirring force of the sulfur slurry mixing device, improves the mixing efficiency of the sulfur slurry mixing device, and effectively shortens the stirring time of the sulfur slurry mixing device.

[0026] This utility model of a sulfur slurry mixing device for reducing stirring time in acid production sulfur slurry storage tanks can effectively solve the problem that sulfur slurry in sulfur slurry storage tanks is prone to sedimentation and stratification after being stored for a period of time, resulting in uneven composition of sulfur slurry. It facilitates rapid mixing and stirring of the sedimented and stratified sulfur slurry in the sulfur slurry mixing device, fully and evenly mixes the sulfur slurry, enhances the mixing force of the sulfur slurry mixing device, improves the mixing efficiency of the sulfur slurry mixing device, and effectively shortens the stirring time of the sulfur slurry mixing device. It is suitable for sulfur slurry mixing devices for acid production sulfur slurry storage tanks that reduce stirring time.
