Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a device for treating brewing wastewater based on a photocatalyst. Background Technology

[0002] Photocatalysts can adsorb organic matter in brewing wastewater and use electrons and holes generated by photoexcitation to carry out oxidation-reduction reactions on the organic matter. These reactions convert the organic matter into harmless or low-toxicity substances. At the same time, photocatalysts can also destroy harmful substances such as microorganisms and viruses in the wastewater.

[0003] In existing technologies, during wastewater treatment, photocatalysts are typically submerged in the wastewater and activated by light to promote the degradation of organic matter. However, when the photocatalyst is submerged, impurities, organic matter, or other deposits from the wastewater accumulate on its surface or in its pores, causing pore blockage and reducing its catalytic activity. Therefore, the photocatalyst needs to be manually removed from the wastewater periodically and rinsed with clean water or a cleaning agent before being returned to the wastewater. However, brewing wastewater contains substances harmful to human health (such as carbon monoxide, methane, and hydrogen sulfide), posing a risk of human harm during the removal and cleaning of the photocatalyst. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a device for treating brewing wastewater based on photocatalyst, so as to solve the problem that there are some harmful substances (such as carbon monoxide, methane, hydrogen sulfide, etc.) in the existing brewing wastewater, and there is a risk of harmful substances harming the human body during the process of removing and cleaning the photocatalyst.

[0005] This utility model is achieved through the following technical solution:

[0006] An apparatus for treating brewing wastewater based on photocatalyst includes a pipe for conveying brewing waste liquid and cleaning agent, the pipe having two input interfaces and one output interface;

[0007] The tube body is provided with a valve core for controlling the connection between the output interface and one of the input interfaces. The valve core has a hollow structure and contains a photocatalyst. A light-emitting part for providing light to the photocatalyst is provided between the tube body and the valve core.

[0008] The outer wall of the valve core has three through holes that connect the inner and outer sides of the valve core. The valve core is rotatably connected to the pipe body, and both the input and output interfaces are located on the rotation trajectory of the through holes. When one of the through holes is connected to the output interface, the other through hole is connected to one of the input interfaces.

[0009] Furthermore, the valve core is spherical, and its outer surface is in contact with the inner surface of the tube.

[0010] A rotating rod is provided outside the valve core. One end of the rotating rod is fixedly connected to the outer surface of the valve core, and the other end extends through the inner wall of the tube and rotates with the tube body.

[0011] Furthermore, a marking strip corresponding to one of the through holes is provided on the outer circular surface of one end of the rotating rod outside the tube. One end of the marking strip is fixedly connected to the outer circular surface of the rotating rod, and the other end extends toward the opening direction of the corresponding through hole.

[0012] Furthermore, a limiting ring is provided on the outer sleeve of the rotating rod, and one end of the limiting ring is fixedly connected to the outer surface of the tube.

[0013] The inner circular surface of the limiting ring is provided with a strip-shaped hole extending in the circumferential direction of the limiting ring, and the marking strip is connected in series in the strip-shaped hole;

[0014] When the marking strip abuts against one side wall of the strip hole in the circumferential direction of the limiting ring, the corresponding through hole is connected to the output interface; when the marking strip abuts against the other side wall of the strip hole in the circumferential direction of the limiting ring, the corresponding through hole is connected to one of the input interfaces.

[0015] Furthermore, the valve core is provided with a storage box for holding the photocatalyst, and the storage box covers the three through-hole openings respectively.

[0016] The storage box has permeation holes on its outer surface opposite to the three through holes, which connect the inside and outside of the storage box. The storage box is detachably connected to the valve core.

[0017] Furthermore, the storage box is inserted into one of the through holes, and the storage box and the corresponding through hole slide in the direction of the through hole opening.

[0018] Furthermore, the outer wall of the storage box is provided with a locking hole extending toward the opening of the corresponding through hole, and a bolt is rotatably fitted in the locking hole;

[0019] The threaded end of the bolt protrudes out of the opening of the locking hole facing the valve core and is inserted into the inner wall of the valve core, and is connected to the inner wall of the valve core through thread engagement.

[0020] Furthermore, the storage box includes a hollow housing with an opening facing the valve core and a cover plate for covering the opening of the housing;

[0021] The shell opening end has sliding grooves on both sides of the opposite side wall. The two edges of the cover plate are respectively embedded in the two sliding grooves and are slidably engaged. The sliding direction of the cover plate on the shell is parallel to the shell opening plane.

[0022] Furthermore, the valve core is made of a light-transmitting material, and a light-emitting chamber, which is isolated from the interior of the valve core, is provided at the connection between the valve core and the rotating rod.

[0023] The light-emitting part includes a light-emitting lamp embedded in the light-emitting chamber. The light-emitting lamp is connected to the rotating rod, and the light emitted by the light-emitting lamp can shine through the outer wall of the valve core onto the surface of the photocatalyst.

[0024] Furthermore, the rotating rod has a hollow structure with openings at both ends, and the opening at the end of the rotating rod facing the valve core is connected to the light-emitting chamber;

[0025] The light-emitting part also includes a connecting post embedded in the rotating rod and a battery electrically connected to the light-emitting lamp. The light-emitting lamp and the battery are both fixedly installed on the end of the connecting post facing the valve core, and the other end of the connecting post is detachably connected to the rotating rod.

[0026] The beneficial effects of this utility model are as follows:

[0027] This device for treating brewing wastewater based on photocatalysts has two input ports and one output port on its pipe body. The two input ports are connected to the brewing wastewater delivery pipeline and the cleaning agent delivery pipeline, respectively. The photocatalyst is placed inside a valve core. When one through-hole on the valve core is connected to the corresponding wastewater input port, the corresponding cleaning agent input port is blocked. The other through-hole is connected to the output port, forming a wastewater flow channel. The photocatalyst is located within this channel. Light emitted by the light-emitting part irradiates the photocatalyst, causing the catalyst to purify the wastewater. By placing the photocatalyst within the wastewater flow channel, the photocatalyst acts as a filter-like structure, increasing the probability of contact between organic matter in the wastewater and the photocatalyst, thus promoting the degradation of organic matter.

[0028] When the photocatalyst needs cleaning, the valve core is rotated to connect one of the through holes to the corresponding input port of the cleaning agent, while blocking the input port of the wastewater. The other through hole connects to the output port, forming a flow channel for the cleaning agent. The photocatalyst is located within this channel, and the flowing cleaning agent washes over the photocatalyst, cleaning it. Therefore, this device can clean the photocatalyst without removing it, reducing the probability of harmful substances being released from the wastewater and coming into contact with the human body, thus protecting the safety of relevant technical personnel.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0041] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0043] In the above description of this utility model, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0045] Please see Figure 1-9 This utility model provides a technical solution: a device for treating brewing wastewater based on photocatalyst, including a pipe body 1 for conveying brewing waste liquid and cleaning agent, wherein the pipe body 1 is provided with two input interfaces 11 and one output interface 12;

[0046] The tube body 1 is provided with a valve core 2 for controlling the connection between the output interface 12 and one of the input interfaces 11. The valve core 2 has a hollow structure and contains a photocatalyst. A light-emitting part for providing light to the photocatalyst is provided between the tube body 1 and the valve core 2.

[0047] The outer wall of the valve core 2 has three through holes 21 that connect the inner and outer sides of the valve core 2. The valve core 2 is rotatably connected to the pipe body 1, and the two input interfaces 11 and the output interface 12 are located on the rotation trajectory of the through holes 21. When one of the through holes 21 is connected to the output interface 12, the other through hole 21 is connected to one of the input interfaces 11.

[0048] In this scheme: two input interfaces 11 and one output interface 12 are set on the pipe body 1. The two input interfaces 11 are connected to the brewing wastewater conveying pipeline and the cleaning agent conveying pipeline, respectively. The photocatalyst is placed inside the valve core 2. When one through hole 21 on the valve core 2 is connected to the corresponding wastewater input interface 11, the corresponding cleaning agent input interface 11 is blocked. The other through hole 21 is connected to the output interface 12, forming a wastewater flow channel. The photocatalyst is located in this channel. Light is emitted by the light-emitting part to irradiate the photocatalyst, so that the catalyst purifies the wastewater. (See attached diagram) Figure 8 The method described above involves placing a photocatalyst within the wastewater flow channel, allowing the photocatalyst to function as a filter-like structure. This increases the probability of organic matter in the wastewater coming into contact with the photocatalyst, thereby promoting the degradation of organic matter.

[0049] When the photocatalyst needs cleaning, the valve core 2 is rotated, connecting one of the through holes 21 to the corresponding input port 11 for the cleaning agent, while blocking the input port 11 for the wastewater. The other through hole 21 connects to the output port 12, forming a cleaning agent flow channel. The photocatalyst is located within this channel, and the flowing cleaning agent washes over the photocatalyst, cleaning it. Therefore, this device can clean the photocatalyst without removing it, reducing the probability of harmful substances being released from the wastewater and coming into contact with the human body, thus protecting the safety of relevant technical personnel. (See attached diagram) Figure 9 As shown.

[0050] In this embodiment: the valve core 2 is spherical, and its outer surface is in contact with the inner surface of the tube body 1;

[0051] A rotating rod 3 is provided outside the valve core 2. One end of the rotating rod 3 is fixedly connected to the outer surface of the valve core 2, and the other end extends through the inner wall of the tube body 1 and rotates with the tube body 1.

[0052] In this design, the valve core 2, rotating rod 3, and pipe body 1 form a ball valve structure. The valve core 2 serves as the ball of this ball valve structure, the rotating rod 3 serves as the valve stem, and the pipe body 1 serves as the valve body. The ball has three interconnected through holes 21, and the valve body has two input ports 11 and one output port 12, making this ball valve a three-way valve. The connection between the output ports 12 and 12 can be adjusted by rotating the rotating rod 3, making operation simple and convenient.

[0053] In this embodiment: the rotating rod 3 is provided with a marking strip 31 on the outer circular surface of one end of the tube body 1, which corresponds to one of the through holes 21. One end of the marking strip 31 is fixedly connected to the outer circular surface of the rotating rod 3, and the other end extends toward the opening direction of the corresponding through hole 21.

[0054] In this scheme: the marker strip 31 is set outside the tube body 1 and is set corresponding to one of the through holes 21, so as to facilitate observation and understanding of the position of the through hole 21 inside the tube body 1, and to provide auxiliary support for adjusting the on / off state of the input interface 11.

[0055] In this embodiment: the rotating rod 3 is fitted with a limiting ring 32, and one end of the limiting ring 32 is fixedly connected to the outer surface of the tube body 1;

[0056] The inner circular surface of the limiting ring 32 is provided with a strip-shaped hole 321 extending in the circumferential direction of the limiting ring 32, and the marking strip 31 is connected in series in the strip-shaped hole 321;

[0057] When the marking strip 31 abuts against the side wall of the strip hole 321 in the circumferential direction of the limiting ring 32, the corresponding through hole 21 is connected to the output interface 12. When the marking strip 31 abuts against the other side wall of the strip hole 321 in the circumferential direction of the limiting ring 32, the corresponding through hole 21 is connected to one of the input interfaces 11.

[0058] In this design, the strip hole 321 serves as the maximum range of rotation for the marker strip 31. By rotating the marker strip 31 to abut against one side wall of the strip hole 321, it is possible to quickly connect the corresponding through hole 21 to the output interface 12 or one of the input interfaces 11, thereby reducing the difficulty of operation.

[0059] In this embodiment: the valve core 2 is provided with a storage box 4 for holding photocatalyst, and the storage box 4 covers the openings of the three through holes 21 respectively;

[0060] The outer surface of the storage box 4, which is opposite to the three through holes 21, is provided with permeation holes 41 that connect the inner and outer sides of the storage box 4. The storage box 4 is detachably connected to the valve core 2.

[0061] In this scheme: storage box 4 is used to store photocatalyst. By opening permeation holes 41 with a diameter smaller than the outer size of photocatalyst on the surface of storage box 4, the photocatalyst is restricted from moving out of storage box 4 through permeation holes 41, thereby reducing the loss of photocatalyst. At the same time, wastewater or cleaning agent can enter storage box 4 to contact photocatalyst for wastewater treatment or cleaning of photocatalyst.

[0062] Furthermore, the storage box 4 is detachably connected to the valve core 2, so that the storage box 4 can be removed from the valve core 2 and the tube body 1 for easy maintenance and cleaning.

[0063] In this embodiment: the storage box 4 is inserted into one of the through holes 21, and the storage box 4 and the corresponding through hole 21 slide in the direction of the opening of the through hole 21.

[0064] In this design: the storage box 4 is prism-shaped, and one of the through holes 21 is adapted to the shape of the storage box 4 to restrict the storage box 4 from swinging freely in the through hole 21. The storage box 4 is tightly connected to the through hole 21 to restrict the storage box 4 from sliding freely out of the through hole 21, so that the storage box 4 stably covers and blocks the three through holes 21.

[0065] In this embodiment: the outer wall of the storage box 4 is provided with a locking hole extending toward the opening direction of the corresponding through hole 21, and a bolt 42 is rotatably fitted in the locking hole;

[0066] The threaded end of the bolt 42 protrudes out of the opening of the locking hole facing the valve core 2 and is inserted into the inner wall of the valve core 2, and is connected to the inner wall of the valve core 2 by thread engagement.

[0067] In this design, the bolt 42 is stepped with an enlarged diameter at the end facing away from the valve core 2 to restrict the bolt 42 from passing through the locking hole. The threaded end of the bolt 42 is inserted into the inner wall of the valve core 2 and connected by thread engagement. The storage box 4 is clamped and fixed to the valve core 2 by the bolt 42, reducing the probability that the storage box 4 will move out of the valve core 2 under the impact of wastewater or cleaning agent.

[0068] In this embodiment: the storage box 4 includes a hollow shell 43 with an opening at one end facing the valve core 2 and a cover plate 44 for covering the opening of the shell 43;

[0069] The shell 43 has grooves 431 on both sides of the opening end. The two edges of the cover plate 44 are respectively embedded in the two grooves 431 and slide in fit. The sliding direction of the cover plate 44 on the shell 43 is parallel to the opening plane of the shell 43.

[0070] In this design: the cover plate 44 is slidably connected to the housing 43, allowing the cover plate 44 to slide on the housing 43 to open the opening of the housing 43, facilitating the addition of photocatalyst into the storage box 4. Simultaneously, the edges of the cover plate 44 are tightly fitted with the sliding groove 431, restricting the cover plate 44 from sliding freely within the sliding groove 431. This ensures that the cover plate 44 continuously and stably covers and seals the opening of the housing 43, limiting the loss of photocatalyst from the opening of the housing 43.

[0071] In this embodiment: the valve core 2 is made of a light-transmitting material, and a light-emitting chamber 22, which is separated from the interior of the valve core 2, is provided at the connection between the valve core 2 and the rotating rod 3;

[0072] The light-emitting part includes a light-emitting lamp 51 embedded in the light-emitting chamber 22. The light-emitting lamp 51 is connected to the rotating rod 3, and the light emitted by the light-emitting lamp 51 can pass through the outer wall of the valve core 2 and irradiate the surface of the photocatalyst.

[0073] In this design, both the valve core 2 and the storage box 4 are made of glass, which has good light transmittance. The light-emitting chamber 22 is spherical, with a concave inner surface. The light-emitting lamp 51 is placed at the center of the light-emitting chamber 22, allowing the light emitted by the lamp to diffuse around the chamber and then irradiate the photocatalyst surface through reflection and refraction.

[0074] The light source 51 is an ultraviolet lamp, and the photocatalyst is a composite nanomaterial (such as SnO2 / ZnO, Ag-TiO2 / SiO2, etc.). These photocatalysts have a significant degradation effect on COD in wastewater under ultraviolet light irradiation. Both the tube body 1 and the rotating rod 3 are made of opaque materials such as plastic or metal to prevent ultraviolet light from penetrating the tube body 1 and escaping outside, thereby reducing the probability of ultraviolet light irradiating the bodies of relevant technical personnel and protecting their health.

[0075] In this embodiment: the rotating rod 3 has a hollow structure with openings at both ends, and the end of the rotating rod 3 facing the valve core 2 is connected to the light-emitting chamber 22;

[0076] The light-emitting part also includes a connecting post 52 embedded in the rotating rod 3 and a battery 53 electrically connected to the light lamp 51. The light lamp 51 and the battery 53 are both fixedly installed on the end of the connecting post 52 facing the valve core 2, and the other end of the connecting post 52 is detachably connected to the rotating rod 3.

[0077] In this design: the storage battery 53 is used to provide power to the light lamp 51, so that the device does not need an external power source, increasing the flexibility of the device; and the light lamp 51 and the storage battery 53 are respectively set in the light-emitting chamber 22 and the rotating rod 3, and the interior of the light-emitting chamber 22 is separated from the interior of the valve core 2, reducing the probability of wastewater and cleaning agent entering the light-emitting chamber 22, and reducing the risk of damage to the light lamp 51 and the storage battery 53 from contact with water.

[0078] The inner surface of the rotating rod 3 facing away from the valve core 2 has an internal thread, and the outer surface of the connecting post 52 has an external thread. The connecting post 52 is inserted into the rotating rod 3 and connected to the rotating rod 3 through a threaded engagement, so as to install the battery 53 and the light lamp 51 on the rotating rod 3. The connecting post 52 can also drive the battery 53 and the light lamp 51 to be moved out of the rotating rod together, so as to facilitate the replacement of the battery 53 and the light lamp 51.

[0079] The cleaning agent is water, the light lamp 51 is an ultraviolet lamp, and the photocatalyst is a composite nanomaterial (such as SnO2 / ZnO, Ag-TiO2 / SiO2, etc.).

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
