Description

Technical Field

[0001] This utility model relates to the field of barite powder storage technology, and in particular to a discharge device for a barite powder storage tank. Background Technology

[0002] Barite powder is a powdery substance produced from barite ore through crushing, grinding, and other processes. Barite, with the chemical composition of barium sulfate, is a common non-metallic mineral. Due to its high density and chemical stability, it is widely used in industries such as oil drilling, chemicals, coatings, and plastics. While barite powder exhibits high flowability and bulk density, its fine particles and hygroscopic nature make it prone to clumping and clogging during storage and transportation, affecting output efficiency and equipment lifespan.4

[0003] In the prior art, patent CN215478526U discloses a discharge device for a barite powder storage tank. This device primarily uses spiral blades to transport the powder, with an inclined plate structure inside the tank assisting in discharge. The spiral blades rotate to transport the barite powder from the bottom of the tank to the discharge port, while the inclined plate guides the powder flow towards the spiral blades. This design improves the continuity and stability of discharge to some extent, but some problems still exist in practical use.

[0004] Although the discharge device in patent CN215478526U features structural optimizations, in practical applications, due to the characteristics of barite powder, the inclined plate structure easily leads to powder retention, especially at the junction of the inclined plate and the tank wall, where powder tends to accumulate and is difficult to discharge completely. Furthermore, the spiral blades may compress the powder during transport, causing it to clump and further affecting the smoothness of discharge. These problems not only reduce discharge efficiency but also increase equipment maintenance costs, impacting the overall performance of the barite powder storage tank. Utility Model Content

[0005] In order to overcome the shortcomings of powder retention and incomplete discharge, this utility model provides a discharge device for barite powder storage tank, which aims to solve the above problems.

[0006] A discharge device for a barite powder storage tank includes a storage tank, a flow guide, an electric slide rail, a flow divider, a motor, a scraper, a control switch, and a vibration assembly. The storage tank has a discharge port at its bottom, and the flow guide is connected to the bottom of the storage tank, located below the discharge port. Several electric slide rails are installed at the bottom of the storage tank, located on both sides of the discharge port. The flow divider is slidably connected to the electric slide rails, and the flow divider is connected to the moving parts of the electric slide rails. All electric slide rails jointly drive the flow divider. The flow divider is sealed to the storage tank. A motor is installed in the middle of the bottom of the storage tank, and the motor's output shaft passes through the bottom plate of the storage tank and is connected to a scraper. A control switch is installed on the storage tank, and the control switch is wired to the motor and the electric slide rails. A vibration assembly for striking the flow divider is installed on the scraper.

[0007] Furthermore, it is particularly preferred that the vibration assembly includes a mounting plate, a striking plate, guide rods, and a return spring. The mounting plate is connected to the scraper, and two guide rods are slidably connected to the mounting plate. The bottom of the two guide rods is connected to the striking plate, which contacts the diverter plate. A return spring is sleeved on the guide rod, with one end of the return spring connected to the mounting plate and the other end connected to the striking plate.

[0008] In addition, it is particularly preferred that the slide rail also includes a telescopic pad, which is provided on the side of the electric slide rail facing the diverter plate. The top of the telescopic pad is connected to the electric slide rail, and the bottom is connected to the diverter plate.

[0009] In addition, it is particularly preferred that a sealing gasket is also included, with the bottom of the storage tank connected to the sealing gasket and the sealing gasket surrounding the discharge port.

[0010] In addition, it is particularly preferred that the guide plate is also included, with the top surface of the diverter plate connected to the guide plate, and both ends of the guide plate being aligned with the electric slide rails.

[0011] In addition, it is particularly preferred that a dust curtain is also included, with the bottom of the deflector connected to the dust curtain.

[0012] 1. By combining the diverter plate and the electric slide rail, the diverter plate can move up and down and seal with the storage tank, effectively solving the problem of powder retention. This enables precise control of the discharge rate, achieving clean discharge and reduced residue.

[0013] 2. Through the cooperation of the scraper and the vibration component, the scraper drives the striking plate to continuously strike the diversion plate during rotation, which effectively solves the problem of powder residue on the diversion plate, thereby realizing the function of vibration cleaning and achieving the purpose of thorough material discharge.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0020] Example: A discharge device for a barite powder storage tank, such as... Figure 1-Figure 4 As shown, the system includes a storage tank 1, a flow guide 3, electric slide rails 4, a flow divider 5, a motor 6, a scraper 7, a control switch 71, and a vibration assembly 8. The storage tank 1 has a discharge port 2 at its bottom, and the flow guide 3 is connected to the bottom of the storage tank 1. The flow guide 3 is located below the discharge port 2 and is wider at the top and narrower at the bottom to limit the discharge area, facilitating container placement. Four electric slide rails 4 are installed at the bottom of the storage tank 1, located on both sides of the discharge port 2. The flow divider 5 is slidably connected to the electric slide rails 4, and the flow divider 5 is connected to the moving parts of the electric slide rails 4. All the electric slide rails 4 work together to drive the flow divider 5. The top of the diversion plate 5 has two inclined surfaces to divert the barite powder to both sides. The diversion plate 5 is sealed to the storage tank 1. A motor 6 is installed in the middle of the bottom of the storage tank 1. The output shaft of the motor 6 passes through the bottom plate of the storage tank 1 and is connected to a scraper 7. A control switch 71 is installed on the storage tank 1. The control switch 71 is wired to the motor 6 and the electric slide rail 4 to control the motor 6 and the electric slide rail 4. When there is enough residual material, the motor 6 is only started when the discharge is completed to smooth out the remaining barite powder in the storage tank 1 for easy material removal in the next cycle. The scraper 7 is equipped with a vibration component 8 for striking the diversion plate 5.

[0021] like Figure 2 and Figure 4As shown, the vibration assembly 8 includes a mounting plate 81, a striking plate 82, guide rods 83, and a return spring 84. The mounting plate 81 is connected to the scraper 7. Two guide rods 83 are slidably connected to the mounting plate 81. The bottom of the two guide rods 83 is connected to the striking plate 82, which contacts the diverter plate 5. The bottom of the striking plate 82 has an inclined surface, and the stroke of the striking plate 82 is less than the height of the inclined surface, meaning the top of the inclined surface always remains in contact with the storage tank 1. A return spring 84 is sleeved on the guide rods 83. One end of the return spring 84... The first end is connected to the mounting plate 81, and the other end is connected to the striking plate 82. When the striking plate 82 contacts the storage tank, the return spring 84 is in a compressed state. When the discharge is about to be completed, the diverting plate 5 approaches the discharge port 2 to reduce the discharge amount. At this time, the motor 6 is started. The motor 6 drives the scraper 7 to stir the barite powder. The striking plate 82 contacts the diverting plate 5. Especially when it is necessary to discharge all the barite powder, the striking plate 82 rotates with the scraper 7. The return spring 84 pushes the striking plate 82 to continuously strike the diverting plate 5, vibrating the powder remaining on the diverting plate 5.

[0022] like Figure 2 As shown, it also includes a telescopic pad 9. The electric slide rail 4 is provided with a telescopic pad 9 on the side facing the diversion plate 5. The top of the telescopic pad 9 is connected to the electric slide rail 4, and the bottom is connected to the diversion plate 5. The bottom of the telescopic pad 9 moves with the diversion plate 5 to prevent powder from entering the electric slide rail 4 and to ensure the cleanliness of the electric slide rail 4.

[0023] like Figure 2 As shown, it also includes a sealing gasket 10. The bottom of the storage tank 1 is connected to the sealing gasket 10, which surrounds the discharge port 2. When the diverter plate 5 contacts the storage tank 1, the sealing gasket 10 can both buffer and optimize the sealing effect.

[0024] like Figure 2 As shown, it also includes a guide plate 11. The top surface of the diverter plate 5 is connected to the guide plate 11. Both ends of the guide plate 11 are aligned with the electric slide rail 4. The connection between the electric slide rail 4 and the diverter plate 5 is designed as an inclined surface to avoid powder retention. When the barite powder falls, it is diverted by the guide plate 11 to further prevent the powder from getting stuck in the gap between the diverter plate 5 and the electric slide rail 4.

[0025] like Figure 2 As shown, it also includes a dust curtain 12. The bottom of the flow guide 3 is connected to the dust curtain 12, which is used to limit the barite powder from escaping to the surroundings and reduce dust.

[0026] Workers store barite powder in storage tank 1. When barite powder needs to be retrieved, the container is placed under the flow guide hood 3. The electric slide rail 4 and motor 6 are activated via control switch 71. Motor 6 drives scraper 7 to rotate slowly, agitating the barite powder in storage tank 1. Simultaneously, the electric slide rail 4 drives the diverter plate 5 to move slowly downwards. When the diverter plate 5 disengages from the outlet 2 of storage tank 1, the barite powder falls from the outlet 2 and enters the container through the flow guide hood 3. The discharge rate can be adjusted by controlling the position of the diverter plate 5 via the electric slide rail 4. During the falling of barite powder, the flow guide hood 3 restricts the discharge area, and the dust curtain 12 prevents powder from escaping and reduces dust. As scraper 7 rotates, it drives the striking plate 82 to rotate via mounting plate 81. When scraper 7 rotates to the outlet 2, the return spring 84 pushes the striking plate 82 downwards, causing it to collide with the diverter plate 5 and vibrate the residual powder on the diverter plate 5. The scraper 7 continues to move, and the inclined surface of the striking plate 82 presses against the storage tank 1. The striking plate 82 moves upward along the guide rod 83, compressing the reset spring 84 to complete the reset. When the barite powder falls onto the diverter plate 5, the guide plate 11 guides the powder flow, preventing the powder from getting stuck in the gap between the diverter plate 5 and the electric slide rail 4. After the discharge is completed, the electric slide rail 4 drives the diverter plate 5 to rise. The bottom outer ring of the diverter plate 5 contacts the sealing gasket 10 to ensure sealing. The telescopic pad 9 moves with the diverter plate 5 to prevent powder from entering the electric slide rail 4 and maintain the normal operation of the electric slide rail 4.

[0027] It should be understood that this embodiment is for illustrative purposes only and is 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 invention, and these equivalent forms also fall within the scope defined by the appended claims.
