Description

Technical Field

[0001] This utility model relates to a pre-washing plate and frame receiving device for titanium dioxide production, belonging to the technical field of receiving equipment. Background Technology

[0002] The pre-washing plate and frame filter press receiving hopper in the membrane washing section is a special component connecting the plate and frame filter press to the feed inlet of the treatment tank. Currently, the receiving hopper has an open structure. Due to the drop difference between the discharge port of the plate and frame filter press and the receiving hopper, the impact and slapping of the filter cake on the receiving hopper during unloading can easily cause liquid splashing. Since the liquid is corrosive, it can easily cause corrosion of the external components of the receiving hopper, affecting its service life. Furthermore, the impact and slapping can easily cause breakage and leakage at the joints of the receiving hopper. A large amount of anti-corrosion and maintenance work is carried out every year, which has a huge impact on the continuity of production. The leaked material causes serious pollution to the site. Utility Model Content

[0003] This invention provides a pre-washing plate and frame receiving device for titanium dioxide production, which solves the problems mentioned in the background art.

[0004] This utility model relates to a pre-washing plate and frame filter press receiving device for titanium dioxide production, including a receiving hopper connecting the outlet of the plate and frame filter press and the inlet of the processing tank. The receiving hopper is surrounded by four fiberglass plates, and the cross-sectional area of ​​the receiving hopper gradually decreases from the upper opening to the lower opening. An upper connecting frame plate and a lower connecting frame plate are fixed to the outer sides of the top and bottom of the four fiberglass plates, respectively. Support components are provided in the middle and lower outer sides of the left fiberglass plate. The support components include multiple support columns arranged in the front-back direction. A support pipe is fixed to the top of each support column, and the top of the support pipe is installed on the left fiberglass plate.

[0005] As a preferred option, both the upper and lower connecting frame plates have connecting flanges on their top outer sides for easy connection and fixing.

[0006] As a preferred embodiment, multiple U-shaped reinforcing steel channels are provided on the outer sides of the four fiberglass panels. The top of the reinforcing steel channel is fixed to the upper connecting frame plate, and the bottom of the reinforcing steel channel is fixed to the lower connecting frame plate. The upper end of the support pipe is welded and fixed inside the U-shaped channel of the reinforcing steel channel. The U-shaped reinforcing steel channel forms a lateral wrapping reinforcement for the fiberglass panels, effectively dispersing the stress on the surface of the fiberglass panels and preventing local bending deformation caused by material impact or its own weight. The reinforcing steel channel is fixed to the upper and lower connecting frame plates to form an integral frame, which greatly improves the rigidity of the receiving hopper structure. The support pipe is welded to the U-shaped channel, which is more stable than directly connecting it to the fiberglass panels.

[0007] As a preferred embodiment, the four corners of the receiving hopper are covered with reinforcing corner plates. The top of the reinforcing corner plates is fixed to the upper connecting frame plate, and the bottom of the reinforcing corner plates is fixed to the lower connecting frame plate. Multiple reinforcing ribs arranged vertically are fixed between adjacent reinforcing channel steel plates and between the reinforcing channel steel plates and the reinforcing corner plates. The reinforcing corner plates specifically reinforce the stress concentration areas at the four corners of the receiving hopper, preventing cracking or deformation at the corners due to excessive stress, and extending the service life of the device. The reinforcing ribs connect the reinforcing channel steel plates and the reinforcing corner plates to form a mesh reinforcement system, allowing localized stress to be quickly transferred to the overall structure, improving the overall structural resistance to deformation. The coordinated reinforcement of multiple components enables the device to adapt to material impacts under different working conditions, improving operational stability and reducing maintenance frequency.

[0008] As a preferred embodiment, the reinforcing channel steel plate is provided with multiple fixing studs passing through it, the fixing studs are fixed to the fiberglass plate, and the fixing studs are provided with locking nuts.

[0009] As a preferred embodiment, each support column is fixed to the top with an L-shaped plate, and side plates are fixed to the front and rear sides of the L-shaped plate. The bottom of the support tube has vertical and horizontal welding mating surfaces that mate with the inner wall of the L-shaped plate. The L-shaped plate provides a bidirectional positioning reference for the support tube, and the combination of vertical and horizontal welding mating surfaces makes the welding connection more precise and the welding fixation more secure.

[0010] As a preferred embodiment, the top of the support pipe is provided with a welded bevel, and a limiting block is fixed inside the U-shaped groove of the reinforcing channel steel plate, extending into the upper inner hole of the support pipe. The limiting block plays a precise positioning role for the support pipe, ensuring that the installation position of the support pipe meets the design requirements. The limiting block extending into the inner hole of the support pipe forms a nested structure, further improving the connection stability between the support pipe and the reinforcing channel steel plate, and making the transmission of support force more direct and efficient.

[0011] As a preferred embodiment, the corners where the four fiberglass panels meet in pairs are equipped with sealing bevels, and the area formed by the two sealing bevels and the inner wall of the reinforcing corner plate is filled with a fiberglass resin layer. The fiberglass resin layer has good sealing and corrosion resistance properties, effectively filling the joint gaps and preventing titanium dioxide slurry from leaking from the joints, ensuring a clean production environment; the fiberglass resin layer is highly compatible with the fiberglass panels and the reinforcing corner plate, forming an integrated sealing structure.

[0012] This utility model has the following beneficial effects: The receiving hopper is enclosed by four fiberglass plates to prevent liquid splashing during unloading. Support components are installed in the middle and lower part of the left fiberglass plate, which bears the main impact force, to improve the overall strength of the hopper and prevent material leakage.

Detailed Implementation

[0014] The present invention will be further described below with reference to the embodiments.

[0015] Example 1, such as Figures 1 to 4 As shown, this utility model is a pre-washing plate and frame filter press receiving device for titanium dioxide production. It includes a receiving hopper connecting the outlet of the plate and frame filter press and the inlet of the processing tank. The receiving hopper is formed by four fiberglass plates 2, with the cross-sectional area gradually decreasing from the top opening to the bottom opening. The fiberglass plates 2 are made of corrosion-resistant glass fiber reinforced plastic, which has advantages such as light weight, high strength, and corrosion resistance. The gradual decrease in cross-sectional area from the top opening to the bottom opening of the receiving hopper forms a funnel shape, facilitating material flow. An upper connecting frame plate 1 and a lower connecting frame plate 4 are fixed to the outer sides of the top and bottom of the four fiberglass plates 2, respectively. Support components are provided on the middle and lower outer sides of the left fiberglass plate 2. The support components include multiple support columns 11 arranged along the front-back direction. A support pipe 9 is fixed to the top of each support column 11, and the top of the support pipe 9 is installed on the left fiberglass plate 2.

[0016] In operation, the upper opening of the receiving device is first connected and fixed to the outlet of the plate and frame filter press via the upper connecting frame plate 1 and the lower connecting frame plate 4, while the lower opening is connected and fixed to the feed inlet of the processing tank. After the titanium dioxide filter cake discharged from the plate and frame filter press enters the receiving hopper, it primarily impacts and beats against the fiberglass plate 2 on the left side. Because the bottom of the fiberglass plate 2 on the left side is equipped with a support component, it can stably support the left fiberglass plate 2, preventing the receiving hopper from opening and causing material leakage. Furthermore, guided by the funnel-shaped structure, the material flows quickly towards the feed inlet of the processing tank. During the material flow process, the fiberglass plate 2 effectively resists the corrosion of the slurry, preventing damage to the device.

[0017] Example 2, based on Example 1, both the upper connecting frame plate 1 and the lower connecting frame plate 4 are provided with connecting flanges 5 on their top outer sides.

[0018] The outer sides of each of the four fiberglass panels 2 are equipped with multiple U-shaped reinforcing channel steel plates 6. The top of the reinforcing channel steel plate 6 is fixed to the upper connecting frame plate 1, and the bottom of the reinforcing channel steel plate 6 is fixed to the lower connecting frame plate 4. The upper end of the support pipe 9 is welded and fixed in the U-shaped groove of the reinforcing channel steel plate 6. The reinforcing channel steel plate 6 is fixedly connected to the upper connecting frame plate 1 and the lower connecting frame plate 4 by welding.

[0019] The four corners of the receiving hopper are covered with reinforcing corner plates 3. The top of the reinforcing corner plates 3 is fixed to the upper connecting frame plate 1, and the bottom of the reinforcing corner plates 3 is fixed to the lower connecting frame plate 4. Multiple reinforcing ribs 7 arranged in the vertical direction are fixed between adjacent reinforcing channel steel plates 6 and between the reinforcing channel steel plates 6 and the reinforcing corner plates 3. The upper connecting frame plate 1, lower connecting frame plate 4, reinforcing channel steel plates 6, reinforcing corner plates 3 and reinforcing ribs 7 work together to ensure the structural stability of the receiving hopper and prevent the receiving hopper from deforming due to material impact.

[0020] The reinforcing channel steel plate 6 is provided with multiple fixing studs 8 passing through it. The fixing studs 8 are fixed to the fiberglass plate 2, and the fixing studs 8 are provided with locking nuts.

[0021] Each support column 11 is fixed to the top of an L-shaped plate 12, and side plates 10 are fixed to the front and rear sides of the L-shaped plate 12. The bottom of the support tube 9 is provided with vertical and horizontal welding mating surfaces 14 that cooperate with the inner wall of the L-shaped plate 12. The height of the top of each support tube 9 is not equal, which can better support the fiberglass plate 2 on the left side.

[0022] The top of the support pipe 9 is provided with a welding bevel. A limiting block 13 is fixed in the U-shaped groove of the reinforcing channel steel plate 6, and the limiting block 13 extends into the upper inner hole of the support pipe 9. When the support pipe 9 is fixed, the top is inserted into the limiting block 13 for quick positioning welding. During welding, the front and rear side walls of the support pipe 9 are also welded and fixed to the side walls of the reinforcing channel steel plate 6. Then, the bottom welding mating surface 14 fits onto the inner wall of the L-shaped plate 12, and then welding is performed. During welding, the front and rear side walls of the support pipe 9 are welded and fixed to the side plate 10.

[0023] Sealing bevels 15 are provided at the corners where the four fiberglass plates 2 meet in pairs. The area formed by the two sealing bevels 15 and the inner wall of the reinforcing corner plate 3 is filled with a fiberglass resin layer 16. The fiberglass resin layer 16 provides a good seal and prevents material from leaking from the joints of the fiberglass plates 2.
