Description

Technical Field

[0001] This utility model relates to the field of titanium iron powder processing technology, and more specifically, to an integrated titanium iron powder screening device. Background Technology

[0002] In the ferrotitanium powder production and processing industry, efficient material screening is a crucial step in ensuring product quality. However, traditional screening equipment encounters numerous problems when dealing with ferrotitanium powder. Due to the uneven particle size distribution of ferrotitanium powder, fine particles easily become trapped between coarse particles, increasing the difficulty of screening; moreover, its strong adhesiveness makes it prone to adhering to the screen mesh, leading to screen blockage. This not only significantly reduces screening efficiency and affects production progress but also requires frequent shutdowns for screen cleaning, increasing maintenance costs. Therefore, we propose an integrated ferrotitanium powder screening device. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an integrated titanium-iron powder screening device to solve the current technical problem of low screening efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an integrated titanium-iron powder screening device, including a metal frame, a side cover plate fixed to the outside of the metal frame, a feed hopper provided on the top of the side cover plate, three fixed frames provided inside the side cover plate, a filter frame provided above the fixed frames, a filter screen plate provided inside the filter frame, a center plate connected to the center of one side of the filter screen plate, the center plate and the side cover plate being rotatably connected, a constraint structure provided on the outer periphery of the filter frame, and a swing structure provided at the bottom of the filter frame.

[0005] Preferably, one side of the filter frame is connected to a swivel cap that can be opened, and one side of the side cover plate is equipped with a detachable side door near the filter frame.

[0006] Preferably, the constraint structure includes an arc shell, which is fixed to the side of the filter frame. The arc shell is arc-shaped and hollow inside. A curved plate is slidably limited inside the arc shell. A connecting plate is fixed to the bottom end of the curved plate. The connecting plate is fixed to the side cover plate. The center point of the arc of the arc shell and the curved plate is the rotation connection point of the center plate.

[0007] Preferably, the oscillating structure includes an oscillating roller, which is located below the filter frame. The outer periphery of the oscillating roller contacts the bottom of the filter screen plate. A driving component is provided on one side of the oscillating roller, and a rotating component is provided on the other side of the oscillating roller.

[0008] Preferably, the driving component includes a track seat, on which a nut seat slides, and a lead screw is fitted at the center of the nut seat, with a drive motor mounted at one end of the lead screw.

[0009] Preferably, the drive component consists of a sawtooth and a rack, the sawtooth being formed at one end of the oscillating roller, the rack being engaged with one side of the sawtooth, and the rack being fixed to the fixed frame.

[0010] Preferably, the oscillating roller is equipped with multiple semi-circular airbags on its outer periphery. Each semi-circular airbag is filled with gas and has a sleeve installed in its center. The bottom end of the sleeve has an air inlet. The top end of the sleeve is slidably mounted with a push rod through a piston limit. The top end of the push rod has a pointed design, and the bottom of the push rod and the inside of the sleeve are provided with tension springs.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model features three fixed frames and a filter frame. The internal filter screen can effectively screen ferrotitanium powder. The combination of the screw cap and side door allows for easy discharge of unqualified products and impurities after filtration, ensuring the continuity and efficiency of the screening process. The combination of the arc shell and the curved plate constrains the swing range of the filter frame. With the rotation connection point of the central plate as the center, the filter frame can stably swing back and forth. The swing structure uses a screw to drive the swing roller to move back and forth at the bottom of the filter frame. By changing the support height on both sides of the bottom, the reciprocating swing sieving is achieved, enhancing the screening effect and solving the problem of low screening efficiency.

[0013] 2. This utility model also utilizes multiple semi-circular airbags installed around the outer periphery of the swing roller. During the reciprocating movement of the swing roller, when the top rod is positioned at the filter hole of the filter screen plate, the bottom periphery of the filter hole will squeeze the semi-circular airbags, causing the top rod to extend and push the filter material inside the filter hole. This effectively avoids the problem of screen clogging caused by the strong adhesiveness of titanium iron powder, reduces the number of times the machine needs to be stopped to clean the screen, lowers maintenance costs, and further solves the problem of low screening efficiency.

[0014] 3. This invention also ensures that the oscillating roller maintains rolling motion during movement through the cooperation of saw teeth and racks, allowing the multiple push rods on the outer periphery to make uniform contact with the filter holes. This not only extends the service life of the equipment but also achieves stable pushing motion, further improving the stability and reliability of screening. Attached Figure Description

Detailed Implementation

[0022] like Figures 1 to 6 As shown, this utility model relates to an integrated titanium-iron powder screening device. The overall structure of this integrated titanium-iron powder screening device mainly consists of a metal frame, side cover plates, a feed hopper, a fixed frame, a filter frame, and a filter screen plate. These components work together to form a complete and efficient screening system. The overall design of the device fully considers the physical properties and screening requirements of titanium-iron powder, aiming to achieve a stable, efficient, and clogging-free screening process.

[0023] Specific components and working principle

[0024] Basic structure of feeding and filtration

[0025] Metal frame and side cover plate: The metal frame 1 serves as the basic support structure of the entire device. It is made of high-strength alloy steel and manufactured through precision welding and processing. It has good rigidity and stability and can withstand various stresses and vibrations during the operation of the device. The side cover plate 2 is fixed to the outside of the metal frame 1 and plays a role in protecting the internal components and preventing dust from escaping. The side cover plate 2 is made of high-quality stainless steel and the surface is polished, which is not only beautiful but also corrosion resistant.

[0026] Feed hopper: The feed hopper 3 is located on the top of the side cover plate 2. Its shape is a funnel with a larger top and a smaller bottom. It is lined with wear-resistant rubber, which can effectively reduce the wear of ferrotitanium powder on the inner wall of the feed hopper 3. The design of the feed hopper 3 allows ferrotitanium powder to enter the device smoothly and evenly, providing good feeding conditions for subsequent screening operations.

[0027] Fixed Frame and Filter Frame: Three fixed frames 4 are set inside the side cover plate 2. The fixed frames 4 are made of aluminum alloy, which is lightweight and high-strength. The main function of the fixed frames 4 is to provide stable support and positioning for the filter frame 5. The filter frame 5 is set above the fixed frames 4, and a filter screen plate 6 is installed inside it. The filter screen plate 6 is made of high-quality stainless steel wire mesh with appropriate mesh size, which can accurately screen according to the particle size requirements of ferrotitanium powder. A center plate 7 is connected to the center of one side of the filter screen plate 6. The center plate 7 is rotatably connected to the side cover plate 2 through a high-precision bearing to ensure that the filter screen plate 6 can swing flexibly.

[0028] Screw cap and side door: A screw cap 10 that can be unscrewed is connected to one side of the filter frame 5. A detachable side door 11 is installed on one side of the side cover plate 2 near the filter frame 5. The design of the screw cap 10 and the side door 11 facilitates the discharge of unqualified products and impurities after filtration. When cleaning or maintenance is required, simply open the corresponding screw cap 10 and side door 11 to quickly remove the internal debris and ensure the normal operation of the device. The filter screen plate 6 can achieve limited sliding through the cooperation of the sliding groove and the slider. This design makes the filter screen plate 6 more stable during swinging and also facilitates its installation and disassembly. In addition, a vibrator or vibration motor can be installed on the side of the filter frame 5 to generate high-frequency vibration to help enhance the vibration effect of the filter screen plate 6 and further improve the screening efficiency.

[0029] Constraint Structure

[0030] Arc shell and curved plate: To achieve stable reciprocating oscillation of the filter frame 5, a constraint structure 8 is provided on the outer periphery of the filter frame 5. The constraint structure 8 includes an arc shell 801, which is fixedly connected to the side of the filter frame 5 by high-strength bolts. The arc shell 801 is arc-shaped and hollow inside, made of high-strength plastic material, with good toughness and wear resistance. A curved plate 802 is limited and slidably mounted inside the arc shell 801. A connecting plate 803 is fixed to the bottom end of the curved plate 802. The connecting plate 803 is fixed to the side cover plate 2 by welding. The arc center point of the arc shell 801 and the curved plate 802 is the rotation connection point of the center plate 7. This design allows the filter frame 5 to reciprocate left and right oscillate around this center point. The cooperation of the arc shell 801 and the curved plate 802 effectively constrains the oscillation range of the filter frame 5, improves the stability of the oscillation process, and avoids the filter frame 5 from shaking or shifting during the oscillation process.

[0031] Oscillating structure

[0032] Swinging roller and driving component: A swinging structure 9 is provided at the bottom of the filter frame 5. The swinging structure 9 includes a swinging roller 901, which is located below the filter frame 5. Its outer periphery is in close contact with the bottom of the filter screen plate 6. The swinging roller 901 is made of high-strength alloy steel and its surface is quenched, giving it good hardness and wear resistance. A driving component 92 is provided on one side of the swinging roller 901. The driving component 92 includes a track seat 921, which is made of high-quality steel and its surface is precision machined to ensure its flatness and straightness. A nut seat 922 slides on the track seat 921, and a screw thread is fitted at the center of the nut seat 922. The screw 923 has a drive motor 924 installed at one end. The drive motor 924 is a high-precision servo motor, which can accurately control the rotation speed and direction of the screw 923. When the drive motor 924 starts, it drives the screw 923 to rotate. The rotational motion of the screw 923 is converted into linear motion through the nut seat 922, thereby driving the swing roller 901 to move back and forth at the bottom of the filter frame 5. By changing the support height of the swing roller 901 on both sides of the bottom of the filter frame 5, the filter frame 5 can swing back and forth to vibrate. This swinging method can make the titanium iron powder roll and move fully on the filter screen plate 6, improving the screening effect.

[0033] Anti-clogging structure

[0034] Semicircular airbags and top rods: To prevent clogging of the filter screen plate 6, multiple semicircular airbags 902 are installed around the outer periphery of the swing roller 901. The semicircular airbags 902 are filled with inert gas, such as nitrogen, to ensure their stability and safety. A sleeve 903 is installed at the center of each semicircular airbag 902. An air inlet is located at the bottom of the sleeve 903, and a top rod 904 is slidably installed at its top via a piston limit. The top of the top rod 904 has a pointed tip, smaller than the aperture of the filter screen plate 6, allowing it to smoothly enter the filter holes. A tension spring 905 is installed at the bottom of the top rod 904 and inside the sleeve 903. The tension spring 905 is made of high-strength material. Made of high-strength spring steel, it has good elasticity and fatigue life. When the swing roller 901 moves back and forth at the bottom of the filter frame 5, and the push rod 904 is at the filter hole position of the filter screen plate 6, the bottom periphery of the filter hole will squeeze the semi-circular air bag 902. After the semi-circular air bag 902 is squeezed, the internal gas enters the inside of the sleeve 903 through the air inlet of the sleeve 903, pushing the push rod 904 to overcome the tension of the tension spring 905 and extend it, pushing the filter material in the filter hole, so that the titanium iron powder or impurities blocked in the filter hole are discharged, thereby avoiding the clogging of the filter screen plate 6 and ensuring the continuous operation of screening.

[0035] Stable rolling structure

[0036] Sawtooth and rack: A drive component 93 is provided on the other side of the oscillating roller 901. The drive component 93 consists of sawtooth 931 and rack 932. The sawtooth 931 is located at one end of the oscillating roller 901 and is machined using a precision milling process to ensure its tooth profile accuracy and surface quality. The rack 932 meshes with one side of the sawtooth 931. The rack 932 is fixedly connected to the fixed frame 4 by bolts. The cooperation between the rack 932 and the sawtooth 931 ensures that the oscillating roller 901 maintains rolling movement when it moves. 1. When the oscillating roller 901 moves back and forth under the action of the drive component 92, the meshing of the saw teeth 931 and the rack 932 causes the oscillating roller 901 to rotate simultaneously. This rolling movement allows the multiple push rods 904 on the outer periphery of the oscillating roller 901 to make uniform contact with the filter holes of the filter screen plate 6, avoiding excessive wear of local push rods or ineffective cleaning of some filter holes. By extending the service life of the equipment, stable pushing of the filter holes is achieved, further improving the anti-clogging effect and screening stability.
