Description

Technical Field

[0001] This utility model relates to the field of titanium dioxide production technology, and more specifically to a rinsing device. Background Technology

[0002] In the sulfuric acid process for producing titanium dioxide, the surface of the hydrolyzed hydrated titanium dioxide adsorbs a large amount of free acid. This adsorbed free acid contains significant amounts of ferrous sulfate and other metal sulfates. The presence of these impurities severely affects the optical properties and pigment performance of titanium dioxide. Water washing is a common method used in titanium dioxide production to remove these impurities. The purpose of water washing is to utilize the fact that hydrated titanium dioxide particles are insoluble in water, while the sulfates of some low-valence metal impurities are soluble. Water washing removes the free acid, unhydrolyzed titanium liquid, and soluble impurity ions, primarily iron, adsorbed on the surface of the hydrated titanium dioxide, thereby purifying the hydrated titanium dioxide.

[0003] When producing titanium dioxide using the sulfuric acid process, a Mohr washing leaf filter is typically used. The machine works as follows: impurities are filtered through a filter cloth, and then, under vacuum conditions, metatitanic acid solids are adsorbed into the interior. The filtrate then flows out through the pores of the filter cloth, while the cloth retains the metatitanic acid solids on its surface. All of this is then placed in a washing tank, where vacuum washing removes the impurities. These steps complete the solid-liquid separation and washing of the metatitanic acid. After the leaf filter has absorbed the particles, unloading is entirely manual, achieved by hand-held high-pressure water rinsing. Due to the large number of leaf filters and the lengthy rinsing process, unloading is extremely labor-intensive, and the amount of water used for manual rinsing cannot be effectively controlled, resulting in large fluctuations in product density.

[0004] In existing technologies, spray nozzle shaking rinsing is often used, resulting in high titanium dioxide residue rates and large fluctuations in water consumption during unloading, which affects the whiteness and particle uniformity of the product. Unloading time is also long, resulting in low unloading efficiency. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of long unloading time and low unloading efficiency in the existing technology, and to provide a rinsing device that shortens the unloading time and improves the unloading efficiency.

[0006] To achieve the above objectives, this utility model provides a rinsing device for rinsing a leaf filter, including an independently set power mechanism and a support mechanism. The power mechanism includes a truss and a base slidably connected to the truss. The rinsing component is slidably connected to the support mechanism and is also connected to the truss so that the rinsing component moves relative to the support mechanism under the drive of the truss.

[0007] Preferably, the base of the power mechanism includes columns and crossbeams connected to two sets of columns. The two sets of crossbeams are slidably connected to the truss. The crossbeams are provided with slide rails. The truss is fixedly connected to a fixed plate. The fixed plate is provided with a slider that is slidably connected to the slide rails.

[0008] Preferably, the crossbeam is also provided with a rack, the fixed plate is provided with a drive device, the gear is fixedly connected to the power output shaft of the drive device, and the gear meshes with the rack.

[0009] Preferably, the support mechanism includes a support column and a track connected to the support column, the track being slidably connected to the flushing assembly.

[0010] Preferably, the support mechanism further includes a support frame equipped with rollers.

[0011] Preferably, stiffening ribs are provided between the support column and the track.

[0012] Preferably, the flushing assembly includes a pipeline and a nozzle disposed on the pipeline. The pipeline is equipped with rollers that are connected to a track, and a pneumatic valve is connected to the pipeline.

[0013] Preferably, the flushing assembly further includes a connector, one end of which is connected to the flushing assembly and the other end of which is connected to the truss.

[0014] Preferably, the pipeline includes a first main pipe and a second branch pipe connected to the first main pipe. The pipeline also includes a third branch pipe connected to the second branch pipe. The third branch pipe is equipped with a nozzle. Rollers are provided at both ends of the first main pipe. The structure of the second branch pipe is matched with the rollers to realize the sliding connection between the rinsing assembly and the support mechanism.

[0015] Preferably, multiple sets of nozzles are provided, and these multiple sets of nozzles are staggered and distributed in the third branch pipe.

[0016] Through the above technical solution, the flushing device of this utility model slidably connects the truss and the base, connects the flushing component to the truss of the power mechanism, and slidably connects the flushing component to the support mechanism. This allows the flushing component to move relative to the support mechanism under the drive of the truss, enabling the flushing distance of the flushing component to the leaf filter to be adjusted. Mechanical operation replaces manual operation, reducing manpower usage, while also improving flushing efficiency and shortening flushing time. Attached Figure Description

[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, inside, outside, far, near, front" are generally used to refer to the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and therefore should not be construed as limiting this utility model.

[0021] like Figures 1-4 A flushing device is shown for flushing a leaf filter, including an independently set power mechanism 1 and a support mechanism 3. The power mechanism 1 includes a truss 11 and a base slidably connected to the truss 11. The flushing component 2 is slidably connected to the support mechanism 3 and is also connected to the truss 11 so that the flushing component 2 moves relative to the support mechanism 3 under the drive of the truss 1.

[0022] Specifically, the rinsing device is used to rinse the filter cloth of the leaf filter. Traditionally, this involves manual rinsing with a water hose, which is time-consuming, labor-intensive, and inefficient. For example... Figure 1As shown, the flushing device used in this utility model includes a power mechanism 1, a flushing component 2, and a support mechanism 3. The power mechanism 1 and the support mechanism 3 are structurally independent, and their bottoms are both connected to the ground. This connection is sufficient to achieve a stable connection between the power mechanism 1, the support mechanism 3, and the ground.

[0023] Specifically, the power mechanism 1 includes a truss 11 and a base. The truss 11 is located on the upper part of the base and is slidably connected to the base. The base is connected to the ground, meaning that the truss 11 and the base can move relative to each other. The support mechanism 3 provides support for the flushing assembly 2 and is slidably connected to the flushing assembly 2, meaning that the flushing assembly 2 and the support mechanism 3 can move relative to each other. The flushing assembly 2 is connected to the truss 11. When the truss 11 moves relative to the base, the truss 11 will drive the flushing assembly 2 to move, thereby allowing the flushing assembly 2 to move relative to the support mechanism 3.

[0024] The flushing device of this utility model allows the flushing component 2 to move under the drive of the truss 11, which is more conducive to flushing the filter cloth of the leaf filter. The relative movement between mechanical structures replaces the traditional manual operation, which is more time-saving and labor-saving. It also makes it easier for the flushing component 2 to flush the filter cloth of the leaf filter from all angles, thus improving the efficiency of leaf filter unloading.

[0025] Furthermore, the base of the power mechanism 1 includes columns 13 and crossbeams 12 connected to the two sets of columns 13. The two sets of crossbeams 12 are slidably connected to the truss 11. The crossbeams 12 are provided with slide rails 15. The truss 11 is fixedly connected to the fixed plate 18. The fixed plate 18 is provided with sliders that are slidably connected to the slide rails 15.

[0026] Specifically, such as Figure 3 and Figure 5 As shown, the base of the power mechanism 1 consists of columns 13 and crossbeams 12. A set of crossbeams 12 connects two sets of columns 13, and a set of trusses 11 connects two sets of crossbeams 12. A fixing plate 18 is fixedly connected to the truss 11; the fixing connection can be welded or bolted, as long as a strong connection is achieved. Each set of crossbeams 12 is equipped with a slide rail 15, specifically located at the top of the crossbeam 12. A slider that mates with the slide rail 15 is located at the bottom of the fixing plate 18. The slider slides on the slide rail 15, causing the fixing plate 18 to move, thereby moving the truss 11 on the crossbeams 12. This achieves relative movement between the truss 11 and the base.

[0027] Furthermore, the crossbeam 12 is also provided with a rack 16, the fixed plate 18 is provided with a drive device 14, the gear 17 is fixedly connected to the power output shaft of the drive device 14, and the gear 17 meshes with the rack 16.

[0028] To improve the automation of rinsing devices, such as Figure 3 and Figure 5As shown, a rack 16 is installed on the side of the crossbeam 12. A drive device 14 is mounted on the fixed plate 18. The drive device 14 can be a servo motor and its driver. The power output shaft of the drive device 14 passes through the fixed plate 18, and a gear 17 that meshes with the rack 16 is installed on the output shaft. When the drive device 14 is started, the power output shaft of the drive device 14 drives the gear 17 to rotate. The gear 17, through the meshing with the rack 16, drives the fixed plate 18 to move, thereby driving the slider to move on the slide rail 15, and also driving the truss 11 to move on the crossbeam 12, thus realizing the automated movement of the truss 11. At the same time, the slide rail 15 and the slider support the weight of the truss 11. The truss 11 is synchronously driven to move laterally by two sets of servo motors and their drivers. Through the transmission of the gear 17, rack 16, slide rail 15, and slider, the truss 11 runs stably and can be positioned accurately.

[0029] Furthermore, the support mechanism 3 includes a support column 31 and a track 32 connected to the support column 31, the track 32 being slidably connected to the flushing assembly 2.

[0030] like Figure 7 and Figure 9 As shown, the support mechanism 3 includes two sets of support columns 31 and one set of tracks 32. The tracks 32 are U-shaped groove tracks 32, and the rinsing assembly 2 is slidably connected to the U-shaped groove tracks 32 to achieve relative movement between the rinsing assembly 2 and the U-shaped groove tracks 32. The connection between the support columns 31 and the tracks 32 can be integrally formed or welded, as long as a stable connection is achieved.

[0031] Furthermore, the support mechanism 3 also includes a frame 34, which is equipped with rollers 35.

[0032] like Figure 7 and Figure 8 As shown, the support mechanism 3 also includes a stand 34, which is an independent structure. Rollers 35 are provided on the stand 34 so that the rinsing assembly 2 can move with the rolling of the rollers 35, thereby reducing the friction between the rinsing assembly 2 and the support mechanism 3 and protecting the rinsing assembly 2.

[0033] Furthermore, stiffening ribs 33 are provided between the support column 31 and the track 32.

[0034] To enhance the load-bearing capacity of support mechanism 3, such as Figure 7 In the embodiment shown, stiffening ribs 33 are provided between the support column 31 and the track 32 to form a triangular and solid support.

[0035] Furthermore, the flushing assembly 2 includes a pipeline and a nozzle 26 disposed on the pipeline. The pipeline is provided with a roller 23, which is connected to the track 32. A pneumatic valve 21 is connected to the pipeline.

[0036] like Figure 6 , Figure 9 As shown, the rinsing assembly 2 is equipped with a water-passing pipeline, and a nozzle 26 is installed on the pipeline body. Rollers 23 are installed on both sides of the pipeline, and the rollers 23 can roll within the U-shaped groove track 32. The rollers 23 can be composite rollers. The output end of the pneumatic valve 21 is connected to the pipeline, and the input end of the pneumatic valve 21 can be connected to a booster pump to pump the cleaning liquid for the leaf filter. The booster pump can be a variable frequency booster pump. The cleaning liquid for the leaf filter is delivered to the pneumatic valve 21 through the booster pump, and after precise flow control, it is delivered to the pipeline and sprayed out through the nozzle 26 to clean the filter cloth of the leaf filter.

[0037] Furthermore, the flushing assembly 2 also includes a connector 24, one end of which is connected to the flushing assembly 2 and the other end of which is connected to the truss 11.

[0038] like Figure 6 As shown, in order to facilitate the connection between the flushing assembly 2 and the truss 11, a connector is provided between the flushing assembly 2 and the truss 11. The flushing assembly 2 is detachably connected to the truss 11 through the connector 24 so that the flushing assembly 2 can be moved when the truss 11 moves.

[0039] Furthermore, the pipeline includes a first main pipe 22 and a second branch pipe 25 connected to the first main pipe 22. The pipeline also includes a third branch pipe 27 connected to the second branch pipe 25. The third branch pipe 27 is provided with a nozzle 26. Rollers 23 are provided at both ends of the first main pipe 22. The structure of the second branch pipe 25 cooperates with the roller 35 to realize the sliding connection between the rinsing assembly 2 and the support mechanism 3.

[0040] The rinsing assembly 2 consists of rinsing assembly units. Specifically, such as... Figures 6-8 In the illustrated embodiment, the pipeline is configured with three sections: a first main pipe 22, a second branch pipe 25, and a third branch pipe 27. Six sets of second branch pipes 25 are connected to one set of first main pipe 22, and one set of third branch pipes 27 are connected to one set of second branch pipes 25. Spray nozzles 26 are disposed on the body of the third branch pipe 27. In other words, a pneumatic valve 21, a first main pipe 22, six sets of second branch pipes 25, six sets of third branch pipes 27, and corresponding spray nozzles 26 constitute the flushing assembly unit.

[0041] It should be noted that, as Figure 7 and Figure 8 In the illustrated embodiment, two sets of support columns 31 and one set of rails 32 constitute a support component unit. The two sets of support component units are arranged facing each other, and six sets of rollers 35 are arranged on the top of the upright frame 34 to support one set of rinsing component units. The height of the rails 32 and rollers 35 must be matched with the height of the rollers 23 to keep the second branch pipe 25 and the first main pipe 22 at the same horizontal position, so as to reduce the inertial movement caused by the pipes themselves.

[0042] Furthermore, multiple sets of nozzles 26 are provided, and these multiple sets of nozzles 26 are staggered and distributed on the third branch pipe 27.

[0043] To improve the rinsing efficiency of the rinsing device, multiple sets of nozzles 26 installed on the third branch pipe 27 can be arranged and staggered, such as... Figure 6 As shown, this allows the rinsing device to spray the filter cloth from various angles when rinsing the filter cloth of the leaf filter. The nozzle 26 can be a fan-shaped stainless steel nozzle, connected to the third branch pipe 27 via a universal joint. The fan-shaped stainless steel nozzle has higher impact force and a larger cleaning range, making it more effective for rinsing the filter cloth.

[0044] The following is as follows Figure 1 The embodiments shown are used to specifically illustrate the technical solution of this utility model.

[0045] like Figure 5 As shown, four sets of columns 13 are connected to a set of crossbeams 12 in pairs. The upper parts of the two sets of crossbeams 12 are equipped with slide rails 15, and the outer sides of the two sets of crossbeams 12 are equipped with racks 16. The two sets of crossbeams 12 are movably connected to the truss 11 via fixed plates 18. Specifically, the fixed plate 18 is equipped with a slider (the slider structure cooperates with the slide rail 15) and a servo motor and its driver. A gear 17 that meshes with the rack 16 is provided at the end of the output shaft of the drive device 14. Fixed plates 18 are symmetrically arranged on both sides of the truss 11. Driven by the servo motor and its driver, the gear 17 rotates at the rack 16, causing the fixed plates 18 to slide on the slide rails 15 of the crossbeams 12, thereby moving the truss 11.

[0046] like Figure 6 and Figure 7 As shown, the rinsing assembly 2 consists of rinsing assembly units, each including a set of pneumatic valves 21, a set of first main pipes 22, six sets of second branch pipes 25, six sets of third branch pipes 27, and corresponding nozzles 26. Each set of pneumatic valves 21 connects to a set of first main pipes 22, each set of first main pipes 22 connects to six sets of second branch pipes 25, and each set of second branch pipes 25 connects to a set of third branch pipes 27. The third branch pipes 27 have staggered nozzles 26 mounted on their bodies. The rinsing assembly units are connected to a truss 11 via a set of connectors 24. A truss 11 can connect multiple rinsing assembly units. Each set of rinsing assembly units has rollers 23 on both sides of its first main pipe 22, which are mounted within a U-shaped track 32. The second branch pipes 25 are mounted on the rollers 35. A booster pump connected to the pneumatic valves 21 pumps cleaning fluid to the first main pipe 22, which is then sprayed out from the nozzles 26 via the second and third branch pipes 25 and 27.

[0047] Corresponding to the configuration of the rinsing component unit, a support mechanism 3 is configured to provide support. Specifically, as shown... Figure 7 , Figure 8 As shown, the support mechanism 3 includes a frame 34 and support component units. The top of the frame 34 is equipped with multiple sets of rollers 35, the number and structure of which correspond to the second branch pipes 25. The support component unit consists of two sets of support columns 31, one set of rails 32, and two sets of stiffening ribs 33, wherein the rails 32 are U-shaped groove rails 32. The two sets of support component units are arranged facing each other. The rollers 23 on both sides of the first main pipe 22 of one set of rinsing component units can roll within the U-shaped groove rails 32, and the six sets of second branch pipes 25 of one set of rinsing component units can move on the rollers 25. This enables the rinsing component 2 to move on the support mechanism 3.

[0048] The above technical solution enables the truss 11 to move under the drive of the servo motor and its driver. The truss 11 drives the flushing assembly 2 to move on the support mechanism 3 through the connector 24, thereby realizing the displacement change of the nozzle 26, which allows the spraying distance to be varied and improves the flushing efficiency of the flushing device.

[0049] It should be noted that the two sets of drive devices 14, the booster pump, and the pneumatic valve 21 are communicatively connected to the PLC (Programmable Logic Controller), and an HMI (Human-Machine Interface) is installed in the central control room, which is also communicatively connected to the PLC. The control system of this invention mainly uses the PLC as the core controller to coordinate the operation of the servo motor and its driver, the booster pump, the pneumatic valve 21, and the corresponding installed flow meters. The HMI is used for human-machine interaction, communicating with the PLC via a network to monitor and operate the control system.

[0050] It should be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0051] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
