Description

A silo pump for drying desulfurization wastewater concentrate Technical Field

[0001] This utility model relates to the field of desulfurization wastewater concentrate drying process technology, and in particular to a silo pump for desulfurization wastewater concentrate drying. Background Technology

[0002] In the flue gas desulfurization process of thermal power plants, limestone-gypsum wet desulfurization systems are usually used. To maintain the chloride ion balance in the desulfurization system, desulfurization wastewater needs to be discharged from the system periodically. Since this wastewater contains a large amount of dissolved salts and other harmful pollutants, it needs to be treated. Currently, triple-effect flash evaporation systems with heat source and vacuum systems are often used to treat the desulfurization wastewater. Low-temperature negative pressure mechanical drying equipment is used to dry and solidify the desulfurization wastewater concentrate. The dried and solidified solid particles are transported to the slag bin by the silo pump ash conveying system, where they are mixed with coal slag for comprehensive utilization. The silo pump consists of a silo tank, discharge valve, feed valve, gas-material conveying pipe, and high-pressure gas supply equipment. Solid particles enter the silo tank through the feed valve, and then the feed valve is closed while the discharge valve and high-pressure gas supply equipment are opened. The solid particles are then transported along the gas-material conveying pipe by a continuous high-pressure airflow.

[0003] In existing technologies, dried sludge particles may agglomerate into lumps due to incomplete drying or compression. These lumpy dried sludge particles will fall directly to the bottom discharge port of the pump after entering the silo pump, impacting the dried sludge particles at the discharge port and causing them to agglomerate and be squeezed together, making it impossible to transport the dried sludge particles normally. To address this, we propose a silo pump for drying desulfurization wastewater concentrate. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a silo pump for drying desulfurization wastewater concentrate.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a tank pump for drying desulfurization wastewater concentrate, comprising a tank, a support mechanism provided on the outer wall of the tank for supporting the tank; a feed pipe fixedly connected to the top of the tank, and an electromagnetic sealing valve connected to the top of the feed pipe via a flange; a conveying mechanism provided at the bottom of the support mechanism for conveying dried sludge particles; and a dispersing mechanism provided inside the tank, the dispersing mechanism including a diffusion hood for impacting the falling dried sludge particles.

[0006] Preferably, the dispersing mechanism further includes a support frame fixedly installed on the inner wall of the tank. One end of the support frame is fixedly connected to a mounting base. A telescopic motor is fixedly connected in the mounting groove of the mounting base. One end of the telescopic rod of the telescopic motor is fixedly connected to the connecting rod at the bottom of the diffuser. The diffuser is located directly below the feed pipe.

[0007] Preferably, the diffuser is in the shape of a trapezoid, an impact ball is fixedly installed on the top trapezoidal surface of the diffuser, a crushing protrusion is fixedly connected to the outer wall of the diffuser, and a pressure relief hole is provided on the outer wall of the diffuser.

[0008] Preferably, the crushing protrusions are arranged in a ring around the axis of the diffuser, the arrangement of the pressure relief holes is staggered with the arrangement of the crushing protrusions, and one end of the crushing protrusion is spherical.

[0009] Preferably, the support mechanism includes a support ring frame fixedly installed on the outer wall of the tank, and a positioning support rod is fixedly connected to the bottom end of the support ring frame.

[0010] Preferably, the conveying mechanism includes a guide seat that is connected to the bottom material port of the tank via a flange, one end of the guide seat is fixedly connected to a pneumatic material conveying pipe, and one end of the pneumatic material conveying pipe is fixedly connected to an electromagnetic airtight valve.

[0011] Preferably, a telescopic sleeve is movably connected between the telescopic motor and the bottom connecting rod of the diffuser cover, and the top of the telescopic sleeve is conical.

[0012] Preferably, a pressure sensor is fixedly connected to the top of the tank, and a pressure compensation pipe is fixedly connected to the top of the tank.

[0013] Beneficial effects:

[0014] 1. The present invention, through the diffusion cover, can guide and diffuse the falling dried sludge particles, effectively preventing the dried sludge particles from falling vertically and concentrating directly to the bottom discharge port, causing the dried sludge particles to be compressed and accumulate, and then clumping again, affecting the conveying of dried sludge particles.

[0015] 2. This utility model uses a telescopic motor fixedly connected inside the mounting base to drive the diffusion hood to move up and down. The high-speed up and down movement of the diffusion hood impacts the dried sludge particles entering the tank, increasing the impact intensity and frequency of the diffusion hood on the dried sludge particles, thereby improving the diffusion effect of the diffusion hood on the dried sludge particles.

[0016] 3. This utility model uses the impact ball head at the top of the diffuser to work with the crushing protrusion fixedly connected to the outer wall of the diffuser to crush the blocky dried sludge particles, making the dried sludge particles finer and facilitating subsequent transportation. At the same time, the pressure relief hole opened on the outer wall of the diffuser can reduce the wind resistance when the diffuser moves up and down. The opening of the pressure relief hole also helps to guide and discharge the small dried sludge particles located on the outer wall of the diffuser. Moreover, the airflow generated when the diffuser moves can be used to blow away the dried sludge particles attached to the outer wall of the diffuser.

[0017] 4. The present invention uses an alternating arrangement of pressure relief holes and crushing protrusions to facilitate the falling of some sludge particles through the pressure relief holes after the crushing protrusions strike and break the dried sludge particles. The crushing protrusions with one end spherical will cause the dried sludge particles to splash when they strike and break the dried sludge particles, thus preventing the dried sludge particles from adhering to the outer wall of the crushing protrusions.

[0024] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0026] Referring to Figures 1-4, a silo pump for drying desulfurization wastewater concentrate includes a silo tank 1. A support mechanism 2 is provided on the outer wall of the silo tank 1 to support the silo tank 1. A feed pipe 6 is fixedly connected to the top of the silo tank 1, and an electromagnetic sealing valve 7 is connected to the top of the feed pipe 6 through a flange. A conveying mechanism 3 is provided at the bottom of the support mechanism 2 to convey the dried sludge particles. A dispersing mechanism 4 is provided inside the silo tank 1. The dispersing mechanism 4 includes a diffusion hood 5 to impact the falling dried sludge particles.

[0027] The dried sludge particles can be introduced into the tank 1 through the feed pipe 6 fixedly connected to the top of the tank 1. The dispersing mechanism 4 set inside the tank 1 impacts the falling dried sludge particles. When the falling dried sludge particles come into contact with the diffusion hood 5, the inclined surface of the diffusion hood 5 will guide the dried sludge particles to diffuse. The force generated by the impact can break up the blocky dried sludge particles, which is convenient for subsequent conveying of the dried sludge particles through the conveying mechanism 3.

[0028] As shown in Figures 2-4, the dispersing mechanism 4 also includes a support frame 8 fixedly installed on the inner wall of the tank 1. One end of the support frame 8 is fixedly connected to a mounting base 9. A telescopic motor 10 is fixedly connected in the mounting groove of the mounting base 9. One end of the telescopic rod of the telescopic motor 10 is fixedly connected to the connecting rod at the bottom of the diffuser hood 5. The diffuser hood 5 is located directly below the feed pipe 6. Through the telescopic motor 10 fixedly connected inside the mounting base 9, the diffuser hood 5 can be driven to move up and down. Thus, the high-speed up and down movement of the diffuser hood 5 impacts the dried sludge particles entering the tank 1, increasing the impact intensity and frequency of the diffuser hood 5 on the dried sludge particles, and improving the diffusion effect of the diffuser hood 5 on the dried sludge particles.

[0029] As shown in Figures 2-4, the diffuser hood 5 is generally trapezoidal in shape. An impact ball head 12 is fixedly installed on the top trapezoidal surface of the diffuser hood 5. A crushing protrusion 13 is fixedly connected to the outer wall of the diffuser hood 5. A pressure relief hole 14 is opened on the outer wall of the diffuser hood 5. During the process of the diffuser hood 5 impacting the dried sludge particles, the impact ball head 12 at the top of the diffuser hood 5 can cooperate with the crushing protrusion 13 fixedly connected to the outer wall of the diffuser hood 5 to crush the blocky dried sludge particles, making the dried sludge particles finer and facilitating subsequent transportation. At the same time, the pressure relief hole 14 opened on the outer wall of the diffuser hood 5 can reduce the wind resistance when the diffuser hood 5 moves up and down. The opening of the pressure relief hole 14 also helps to guide and discharge the small dried sludge particles located on the outer wall of the diffuser hood 5. Moreover, the airflow generated when the diffuser hood 5 moves can be used to blow away the dried sludge particles attached to the outer wall of the diffuser hood 5.

[0030] As shown in Figures 2-4, the crushing protrusions 13 are arranged in a ring around the axis of the diffuser hood 5, which can make the damage points evenly distributed. The arrangement of the pressure relief holes 14 is staggered with that of the crushing protrusions 13. The staggered arrangement makes it convenient for some sludge particles to fall through the pressure relief holes 14 after the crushing protrusions 13 hit and break the dried sludge particles. One end of the crushing protrusions 13 is spherical. When the crushing protrusions 13 hit and break the dried sludge particles, the dried sludge particles will splash, preventing the dried sludge particles from adhering to the outer wall of the crushing protrusions 13.

[0031] As shown in Figures 1 and 2, the support mechanism 2 includes a support ring frame 15 fixedly installed on the outer wall of the tank 1. A positioning support rod 16 is fixedly connected to the bottom end of the support ring frame 15. At the same time, the support ring frame 15 and the positioning support rod 16 can support and position the tank 1 to prevent the tank 1 from tipping over under force.

[0032] As shown in Figures 1 and 2, the conveying mechanism 3 includes a guide seat 17 that is connected to the bottom material port of the silo 1 via a flange. A gas conveying pipe 18 is connected through the guide seat 17. An electromagnetic airtight valve 19 is fixedly connected to one end of the gas conveying pipe 18. The dried sludge particles inside the silo 1 can be discharged through the guide seat 17. The electromagnetic airtight valve 19 fixedly connected to one end of the gas conveying pipe 18 can be connected to a high-pressure gas supply pipe. The high-pressure gas drives the dried sludge particles inside the guide seat 17 to move along the material conveying pipe of the guide seat 17. The guide seat 17 is barrel-shaped with a built-in sealing valve at the top. This is an existing device and will not be described in detail here.

[0033] As shown in Figures 1-3, a telescopic sleeve 11 is movably connected between the telescopic motor 10 and the bottom connecting rod of the diffuser 5. The top of the telescopic sleeve 11 is conical, and the tapered telescopic sleeve 11 can cover the connection between the telescopic motor 10 and the bottom connecting rod of the diffuser 5 to prevent dust.

[0034] As shown in Figures 1 and 2, a pressure sensor 20 is fixedly connected to the top of the tank 1, and a pressure compensation pipe 21 is fixedly connected to the top of the tank 1. The pressure sensor 20 fixedly connected to the top of the tank 1 can measure the internal pressure of the tank 1, and the pressure compensation pipe 21 fixedly connected to the top of the tank 1 can be connected to an external air supply pipe to regulate the internal air pressure of the tank 1.

[0035] The working principle of this utility model is as follows: The electromagnetic sealing valve 7, fixedly connected to the top of the feed pipe 6, is connected to the dried sludge particle discharge pipe of the desulfurization wastewater concentrate dryer. Then, the high-pressure air pump is connected to the electromagnetic airtight valve 19 at one end of the gas-material conveying pipe 18, and the other end of the gas-material conveying pipe 18 is connected to the conveying pipeline. The electromagnetic sealing valve 7 is opened, allowing the dried sludge particles to be discharged into the silo 1 along the feed pipe 6. The telescopic motor 10 is then activated, using it to drive the diffuser hood 5 to move up and down, thus adjusting the position of the hood. The dried sludge particles are crushed by impact. After impact, the dried sludge particles will roll down the outer wall of the diffuser hood 5 to the bottom of the tank 1. Then, the electromagnetic sealing valve 7 is closed and the guide seat 17 is opened, so that the dried sludge particles inside the tank 1 fall into the guide seat 17. Then, the electromagnetic airtight valve 19 at one end of the gas-material conveying pipe 18 is opened, and high-pressure gas is supplied to the guide seat 17 by a high-pressure air pump. The gas pushes the dried sludge particles along the gas-material conveying pipe 18 into the material conveying pipe, thus completing the conveying of the dried sludge particles.
