Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to an antibiotic wastewater treatment device. Background Technology

[0002] Antibiotic wastewater treatment is a complex issue involving environmental protection and public health. Antibiotic residues enter water bodies through various pathways, including medical wastewater, agricultural discharges, and pharmaceutical industrial wastewater. These antibiotic residues can not only pollute water bodies but also pose threats to aquatic ecosystems and human health, as they may lead to the emergence of antibiotic-resistant bacteria, affecting ecological balance and treatment effectiveness.

[0003] Problems with existing technology: In the process of treating antibiotic wastewater, the discharged wastewater needs to be initially filtered to remove large solid particles for better subsequent treatment. Bar screens are a common filtration device that can filter large particles. However, because they filter through gaps between metal plates, the filtration effect is relatively poor, and sticky substances tend to adhere to the transmission teeth, further reducing the filtration efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an antibiotic wastewater treatment device that can clean the sticky substances adhering to the transmission teeth with high-pressure air and helical teeth, while also adsorbing and filtering smaller solid particles to increase the filtration effect.

[0005] The specific technical solution adopted by this utility model is as follows: An antibiotic wastewater treatment device includes: a wastewater well; a bar screen housing located above the wastewater well; a motor protective housing located above the bar screen housing; filter chains driven on both sides of the interior of the bar screen housing; multiple drive teeth located in the middle of the filter chains on both sides; teeth fixedly installed on both sides of the drive teeth; reverse teeth fixedly installed below the upper platform of the bar screen housing; filter screens located between two adjacent drive teeth; and an air outlet pipe installed inside the upper part of the bar screen housing, with an air outlet on one side facing the reverse teeth and the filter screen.

[0006] The two ends of the reverse teeth are detachably installed on the inner wall of the bar screen housing, and the top of the reverse teeth is fixedly installed with oblique teeth, which are interleaved with the teeth.

[0007] The reverse tooth has a groove near the two adjacent oblique teeth, and one side of the oblique tooth is inclined.

[0008] Flexible connecting strips are fixedly connected to both sides of the filter screen, and the two ends of the flexible connecting strips are respectively fixedly connected to two adjacent transmission teeth.

[0009] The flexible connector is fixedly connected to a diamond-shaped buckle near the pin of the filter chain.

[0010] The pins on the side of the filter chain closest to the flexible connector extend 1cm-3cm.

[0011] The pin extends outwards from one end and has a diamond-shaped groove inside, and the diamond-shaped buckle is inserted into the diamond-shaped groove for connection.

[0012] The top and bottom of the diamond-shaped slot extend to the outer edge of the pin, and the diamond-shaped slot forms two holes at the top and bottom of the pin end.

[0013] The width of the hole described above is smaller than the width of the hole described below.

[0014] A fan is installed on the side of the wastewater well near the outer casing of the bar screen, and the output end of the fan is connected to the air outlet pipe through a pipeline.

[0015] The technical effects achieved by this utility model are as follows: In this invention, when the transmission tooth reaches the position of the reverse tooth, the teeth of the transmission tooth will move relative to the helical tooth in a cross-shaped manner. The helical tooth can push the adhesive on the teeth away from the teeth. The inclined side of the helical tooth and the inclined groove are used to facilitate the sliding off of the adhesive.

[0016] This invention uses a fan to inject a large amount of air into the air outlet pipe, and then blows high-pressure gas out through the air outlet of the air outlet pipe to the filter screen and the transmission teeth at the reverse gear, blowing off the solid particles adhering to them.

Detailed Implementation

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1 As shown, an antibiotic wastewater treatment device includes: a wastewater well 1, a bar screen housing 2 located above the wastewater well 1, a motor protective housing 3 located above the bar screen housing 2, filter chains 201 being driven and installed on both sides inside the bar screen housing 2, a plurality of drive teeth 203 being located in the middle of the filter chains 201 on both sides, and teeth being fixedly installed on both sides of the drive teeth 203.

[0021] In a traditional bar screen, the bar screen housing 2 is fixed to one side of the drainage well opening. A collection bucket is placed under the platform at the end of the bar screen housing 2. The collection bucket extends into the well through the filter chain 201. Wastewater in the well flows from one side of the filter chain 201 through the filter chain 201 to the other side. During this process, solid particles are blocked by the transmission teeth 203. The blocked solid particles are lifted upward by the teeth on the transmission teeth 203. When they reach the position below the platform of the bar screen housing 2, the transmission teeth 203 are in a vertical state. The solid particles lose the support of the transmission teeth 203 and fall under the action of gravity, thus achieving the filtration and collection of solid particles. The motor protective housing 3 houses a motor, the output end of which is connected to the filter chain 201 via a gear drive to drive the filter chain 201.

[0022] See attached document Figures 2-3 A reverse tooth 205 is fixedly installed below the upper platform of the bar screen housing 2. The two ends of the reverse tooth 205 are detachably installed to the inner wall of the bar screen housing 2. A helical tooth 207 is fixedly installed on the top of the reverse tooth 205. The helical tooth 207 is interleaved with the tooth. A helical groove 206 is opened near the two adjacent helical teeth 207 of the reverse tooth 205. One side of the helical tooth 207 is inclined.

[0023] According to the above structure, the filter chain 201 is divided into upper and lower layers on the platform. The reverse tooth 205 is fixed below the lower filter screen 204 on the platform. When the transmission tooth 203 carries solid particles and other debris to the lower filter chain 201 on the platform, the transmission tooth 203 will be placed vertically under the traction of the filter chain 201. When the transmission tooth 203 reaches the position of the reverse tooth 205, the teeth of the transmission tooth 203 will move relative to the inclined tooth 207. The inclined tooth 207 can push the adhering material on the teeth away from the teeth. One side of the inclined tooth 207 is inclined and the inclined groove 206 is used to facilitate the sliding of the adhering material. Among them, the reverse tooth 205 is disassembled and installed from the bar screen housing 2 by means of bolts, etc., so as to facilitate its replacement and cleaning.

[0024] See attached document Figures 4-7 A filter screen 204 is provided between two adjacent transmission teeth 203; a flexible connecting strip 208 is fixedly connected to both sides of the filter screen 204, and the two ends of the flexible connecting strip 208 are fixedly connected to two adjacent transmission teeth 203 respectively; a diamond-shaped buckle 209 is fixedly connected to the flexible connecting strip 208 near the pin of the filter chain 201; the pin of the filter chain 201 near the flexible connecting strip 208 extends 1cm-3cm; a diamond-shaped groove 210 is opened inside the extended end of the pin, and the diamond-shaped buckle 209 is inserted into the diamond-shaped groove 210; the top and bottom of the diamond-shaped groove 210 extend to the outer edge of the pin, and the diamond-shaped groove 210 forms two holes at the top and bottom of the pin end; the width of the upper hole is smaller than the width of the lower hole.

[0025] According to the above structure, the filter screen 204 is connected to the filter chain 201 through the flexible connecting strip 208. The filter screen 204 is mesh-like and has dense through holes. When the wastewater passes through the filter screen 204, solid particles will be adsorbed by the through holes and carried out of the wastewater well 1, reaching the platform at the top of the bar screen housing 2. Under the traction of the filter chain 201, they will reach the lower layer. At this time, the side of the through hole that adsorbs solid particles faces the ground and falls into the inside of the collection bucket under the action of gravity. The filter screen 204, the transmission gear 203, and the flexible connecting strip 208 are integrated into one unit. Both the filter screen 204 and the flexible connecting strip 208 are made of soft materials and are connected by glue, welding, or other methods. During installation, both ends of the transmission gear 203 are fixedly connected with positioning pins. The positioning pins are inserted into the filter chain 201 to prevent the transmission gear 203 from rotating. The two are then connected and fixed by bolts passing through the pins of the filter chain 201. The filter screen has 204 through holes oriented in the direction of wastewater flow, which are cylindrical at one end and conical at the other, so that it can better adsorb solid particles. The diamond-shaped buckle 209 is inserted into the diamond-shaped slot 210. The diamond-shaped buckle 209 is made of elastic steel or stainless steel. During the insertion process into the diamond-shaped slot 210, it is found to be elastically deformed. After entering the diamond-shaped slot 210, it returns to its original shape, thereby limiting the flexible connecting strip 208. The orientation of the hole on the diamond-shaped slot 210 is the direction of wastewater flow, so that if an object enters from the upper hole, it can be discharged from the lower hole to prevent blockage. In general, the filter chain 201 is composed of inner and outer chain pieces connected by pins, which are existing structures.

[0026] See attached document Figures 1-2 An air outlet 202 is installed inside the upper part of the bar screen housing 2. An air outlet is opened on one side of the air outlet 202 and faces the reverse teeth 205 and the filter screen 204. A fan 4 is installed on the side of the wastewater well 1 near the bar screen housing 2. The output end of the fan 4 is connected to the air outlet 202 through a pipe.

[0027] According to the above structure, when the filter screen 204 or the transmission gear 203 reaches the platform of the bar screen housing 2, the side with solid particles will face the ground. Under the action of gravity, the solid particles will fall into the collection bucket. During this process, some solid particles are sticky and do not fall easily. At this time, a large amount of air needs to be injected into the air outlet pipe 202 by the fan 4, and then high-pressure gas is blown out through the air outlet of the air outlet pipe 202 to the filter screen 204 and the transmission gear 203 at the reverse gear 205 to blow off the solid particles attached to them.

[0028] The working principle of this utility model is as follows: The filter chain 201 is divided into upper and lower layers on the platform. When the transmission tooth 203 carries solid particles and other debris to the lower layer of the filter chain 201 on the platform, when the transmission tooth 203 reaches the position of the reverse tooth 205, the teeth of the transmission tooth 203 will move relative to the oblique tooth 207. The oblique tooth 207 can push the adhering material on the teeth away from the teeth. When the filter screen 204 or the transmission tooth 203 reaches the platform of the grid machine housing 2, the side with solid particles will face the ground. During this process, some solid particles are sticky and not easy to fall off. At this time, a large amount of air needs to be injected into the air outlet pipe 202 by the fan 4, and then high-pressure gas is blown out through the air outlet of the air outlet pipe 202 to the filter screen 204 and the transmission tooth 203 at the reverse tooth 205 to blow off the solid particles adhering to them.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
