Description

Technical Field

[0001] This invention relates to the field of water pollution control, specifically to a wastewater treatment device for catalyst recovery. Background Technology

[0002] A catalyst is a substance that increases the reaction rate without altering the overall standard Gibbs free energy change. During catalyst recycling, various chemicals are used for cleaning and treatment to remove impurities from the catalyst surface and restore its activity. These chemicals need to be washed away after the reaction, resulting in wastewater containing catalyst residues, cleaning agent residues, and other impurities.

[0003] Traditional wastewater treatment devices employ a process of reaction and sedimentation followed by filtration of the upper liquid. Patent application CN202510677836.3 discloses an industrial wastewater treatment device that includes a treatment tower. The treatment tower has an openable and closable door that divides the space inside the treatment tower into an upper reaction chamber and a lower sedimentation chamber. This process requires a long sedimentation time and has low treatment efficiency.

[0004] Therefore, a new type of wastewater treatment device for catalyst recovery is needed. Summary of the Invention

[0013] As a further aspect of the present invention: a funnel-shaped collecting hopper is provided at the connection between the discharge port and the inner cylinder, and a vertical cylindrical tube is connected to the bottom of the collecting hopper.

[0015] As a further aspect of the present invention: the upper and lower surfaces of the cover plate and the upper surface of the top rod are both conical surfaces. Beneficial effects

[0016] 1. The present invention has a guide tube rotatably connected to the inner cylinder. The guide tube is driven to rotate by a drive motor, which causes the liquid inside the inner cylinder to rotate, forming a vortex. This causes impurities to accumulate at the bottom center, while the water is thrown out to the outside of the inner cylinder through the top opening and discharged through the water outlet pipe. The drive motor is fixedly installed on the top cover of the outer cylinder. The bottom center of the outer cylinder is welded with a discharge port that communicates with the space inside the inner cylinder. The communication between the discharge port and the inner cylinder is closed by a discharge valve. By opening the discharge valve, the impurities accumulated in the center of the inner cylinder are discharged into the discharge port.

[0017] 2. The cross-section of the guide tube of the present invention is H-shaped, and the inner tube structure extends into the opening of the H-shaped structure. The bottom surface of the guide tube and the bottom surface of the outer tube are vertically spaced. The connection between the water inlet pipe and the inner tube is located within the interval. The water inlet pipe extends into the inner tube along the tangential direction of the inner tube, so that a larger diameter space is formed on the lower side of the guide tube that drives the water flow to rotate. This reduces the direct entry of water containing impurities into the upper layer and mixing with the clear water after the dirt is collected. Moreover, the water inlet in the tangential direction can also drive the rotation.

[0018] 3. The discharge valve of the present invention includes a telescopic cylinder, a connecting plate, a support rod, and a cover plate. The telescopic cylinder is fixed at the bottom of the discharge port, and the bottom end is connected to the connecting plate. The connecting plate is threadedly connected to the connecting rod by a fixing nut. The top end of the connecting rod is provided with a support rod and a cover plate, forming an hourglass-shaped structure to seal the connection between the discharge port and the inner cylinder. The reciprocating motion of the hourglass-shaped structure carries down the accumulated impurities in the middle and achieves the sealing of the connection between the discharge port and the inner cylinder.

[0030] This embodiment provides a wastewater treatment device for catalyst recovery, such as... Figure 1 , Figure 2 , Figure 4As shown, the device includes an outer barrel with a top opening. An inner cylinder with a top opening is concentrically welded to the bottom center of the inner side of the outer barrel. A water inlet pipe runs through the structure of the outer barrel and the inner cylinder and enters the inner cylinder. A water outlet pipe is connected to the bottom surface of the outer barrel between the inner cylinder and the outer barrel. A guide cylinder is rotatably connected to the inner cylinder. The guide cylinder is driven to rotate by a drive motor, which causes the liquid in the inner cylinder to rotate, forming a vortex. This causes impurities to accumulate at the bottom center, while the water is thrown out through the top opening to the outside of the inner cylinder and discharged through the water outlet pipe. The drive motor is fixedly installed on the top cover of the outer barrel. A discharge port that communicates with the space inside the inner cylinder is welded to the bottom center of the outer barrel. The communication between the discharge port and the inner cylinder is closed by a discharge valve. By opening the discharge valve, the impurities accumulated in the center of the inner cylinder are discharged into the discharge port.

[0031] like Figure 4 , Figure 5 As shown, the guide tube is nested inside the inner cylinder, and the inner wall is provided with threaded ribs to drive the water flow to rotate. The guide tube has an H-shaped cross-section, and the inner cylinder structure extends into the opening of the H-shaped structure. The bottom surface of the guide tube and the bottom surface of the outer cylinder are vertically spaced. The connection between the water inlet pipe and the inner cylinder is located within the interval. The water inlet pipe extends into the inner cylinder along the tangential direction, so that the lower side of the guide tube that drives the water flow to rotate forms a larger diameter space, reducing the direct entry of water containing impurities into the upper layer and mixing with the clear water after sludge collection. The tangential water inlet can also drive the rotation. The circumference of the guide tube and the corner of the H-shaped structure are provided with a drive ring, which is connected to the drive motor through a transmission belt. The top of the inner cylinder is inclined with a support roller to support the corner of the H-shaped structure and reduce the fluctuation during driving. The top of the inner cylinder has an inwardly protruding side edge structure that fits into the inner layer structure of the guide tube. A sealing ring is set at the fit of the structure, thereby restricting the water flow out of the opening of the H-shaped structure of the guide tube.

[0032] like Figure 6 As shown, the top of the guide tube has an inward-curving arc structure, which reduces the diameter of the water outlet of the guide tube, increases the amount of water curtain formed inside the guide tube, slows down the water discharge speed, and improves the filtration effect.

[0033] like Figure 8 , Figure 9 As shown, the discharge valve includes a telescopic cylinder, a connecting plate, a support rod, and a cover plate. The telescopic cylinder is fixed at the bottom of the discharge port, and the bottom end is connected to the connecting plate. The connecting plate is threadedly connected to the connecting rod by a fixing nut. The top end of the connecting rod is equipped with a support rod and a cover plate, forming an hourglass-shaped structure to seal the connection between the discharge port and the inner cylinder. The reciprocating motion of the hourglass-shaped structure carries down the accumulated impurities in the middle and achieves the sealing of the connection between the discharge port and the inner cylinder.

[0034] Furthermore, a funnel-shaped collecting hopper is installed at the connection between the discharge port and the inner cylinder to guide and collect accumulated impurities. The bottom of the collecting hopper is connected to a vertical cylindrical tube, through which the support rod and cover plate pass. The vertical distribution height of the hourglass-shaped structure is less than the height of the cylindrical tube, so that when the hourglass-shaped structure formed by the support rod and cover plate passes through the collecting hopper, the upper and lower ends always remain closed at one end, preventing the liquid in the upper inner cylinder from directly entering the discharge port.

[0035] The connecting rod has a cover plate fixedly connected to its top and a support rod slidably connected to its middle section. The bottom of the connecting rod has a hollow guide groove with a compression spring embedded inside. The other end of the compression spring is connected to the support rod via a stop plate, which elastically limits the position of the support rod on the connecting rod. At the same time, the circumference of the support rod has a stepped structure, which, in conjunction with the discharge port structure, limits the vertical movement of the support rod. When the connecting rod, cover plate, and support rod move downward under the action of the telescopic cylinder and the connecting rod, the stepped structure of the support rod moves to a point where it comes into contact with the discharge port structure, and then it will generate relative displacement with the cover plate, squeezing the impurities accumulated on the circumference and assisting in the discharge of the accumulated impurities. When resetting, the cover plate and support rod will reset their relative positions under the action of the compression spring.

[0036] Meanwhile, the upper and lower surfaces of the cover plate and the upper surface of the top rod are all conical surfaces, which squeeze the impurity blocks in the middle when the support rod and the cover plate compress the distance, making it easier for the impurity blocks to be crushed and decomposed and discharged. The conical surface at the top of the cover plate guides the impurities accumulated at the top to fall down when the discharge valve is reset, preventing them from accumulating at the top of the cover plate.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
