Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment and recycling device. Background Technology

[0002] Wastewater generated from medical device manufacturing typically has a complex composition and characteristics. This wastewater may contain various chemicals, such as cleaning agents, disinfectants, and surfactants, as well as residues of raw materials used in the production process, and metal ions. Some of these components are toxic, biodegradable, and pose potential environmental hazards. Furthermore, due to the diversity of medical device manufacturing processes, the volume and quality of the wastewater can fluctuate significantly. Some wastewater may exhibit high concentrations, high color, and strong acidity or alkalinity. Direct discharge without effective treatment can cause serious environmental pollution, disrupt the ecological balance, impair the self-purification capacity of water bodies, and even threaten human health and the stability of ecosystems.

[0003] Medical equipment wastewater treatment and recycling equipment requires the purification of wastewater through a reaction between drugs and wastewater. However, existing drug-wastewater contact reactions may be uneven, resulting in unsatisfactory wastewater treatment effects. Therefore, a wastewater treatment and recycling equipment is proposed.

The neutralization and stirring mechanism includes:

[0006] A partition is fixedly installed at the bottom of the sand and gravel layer, and a partition is fixedly installed on the inner wall of the main body;

[0007] A mesh cylinder is fixedly connected to the inner wall of the partition layer, and a mesh cylinder is attached to the inside of the sand and gravel layer. Through the adsorption of the sand and gravel layer, relatively clean treated water can flow through the mesh cylinder to the next layer.

[0008] A protrusion is fixedly connected to the bottom of the partition.

[0009] Preferably, a turntable is rotatably connected to the inner wall of the partition, a telescopic rod is fixedly connected to the outer wall of the turntable, and a spring is slidably connected to the outer wall of the telescopic rod.

[0010] Preferably, a stirring rod is fixedly connected to the bottom of the telescopic rod. By the contraction of the telescopic rod and the rebound force of the spring, the stirring rod can be brought closer to the partition. A sliding column is fixedly connected to the top of the stirring rod, and a protrusion is slidably connected to the top of the sliding column. By rotating the stirring rod, the sliding column can slide on the surface of the protrusion under force.

[0011] Preferably, the outer wall of the main shaft is provided with a sliding groove, and the inner wall of the stirring rod is slidably connected to the sliding groove. By means of the spring's rebound force, the inner wall of the stirring rod can slide up and down on the groove.

[0012] Preferably, the filtration mechanism includes a sweeping plate, which is fixedly connected to the outer wall of the main shaft. By rotating the main shaft, the sweeping plate can clean impurities. A sleeve is slidably connected to the bottom of the sweeping plate, and the sleeve is rotatably connected to the outer wall of the main shaft.

[0014] Compared with the prior art, the present invention provides a wastewater treatment and recycling device, which has the following beneficial effects:

[0015] 1. This wastewater treatment and recycling equipment is designed to treat acidic and alkaline substances in wastewater. The operator starts the motor, and the treated water permeates through the partition layer, flows through the mesh cylinder to the neutralization layer, and is then added with appropriate chemicals. The main shaft drives the stirring rod, causing the sliding column to rotate. The sliding column is lifted by the convex inclined surface, stretching the telescopic rod and spring. The sliding column slides along the low inclined surface, and the spring's rebound force pulls the stirring rod, causing it to rotate and move up and down simultaneously, thus ensuring a more complete neutralization reaction of the treated water.

[0016] 2. In order to minimize the risk of impurities in the wastewater, this wastewater treatment and recycling equipment allows operators to avoid the wastewater entering the main body. The wastewater flows to the lower layer through the mesh of the circular screen, while the impurities are blocked on the surface. The rotating surface of the sweeping plate rotates the impurities, causing them to fall off when passing through the slag discharge port. The impurities are accumulated by the clamping plate, and pulling up the clamping plate allows the impurities to flow into the garbage can, making cleaning very convenient.

A mesh cylinder 92 is fixedly connected to the inner wall of the partition 91. The mesh cylinder 92 is adhered to the inside of the sand and gravel layer 8. Through the adsorption of the sand and gravel layer 8, relatively clean treated water can flow to the next layer through the mesh cylinder 92. A protrusion 93 is fixedly connected to the bottom of the partition 91, and a turntable 94 is rotatably connected to the inner wall of the partition 91. A telescopic rod 95 is fixedly connected to the outer wall of the turntable 94. The telescopic rod 95 has a spring 96 slidably connected to its outer wall. The bottom of the telescopic rod 95 is fixedly connected to a stirring rod 97. By the contraction of the telescopic rod 95 and the rebound force of the spring 96, the stirring rod 97 can be brought closer to the partition 91. The top of the stirring rod 97 is fixedly connected to a sliding column 98. The top of the sliding column 98 is slidably connected to a protrusion 93. By rotating the stirring rod 97, the sliding column 98 can slide on the surface of the protrusion 93 under force. The outer wall of the main shaft 5 is provided with a sliding groove 99. The inner wall of the stirring rod 97 is slidably connected to the sliding groove 99. By the rebound force of the spring 96, the inner wall of the stirring rod 97 can slide up and down on the sliding groove 99.

[0025] Specifically, the filtration mechanism 7 includes a sweeping plate 71, a sleeve 72, a circular screen 73, a fixed plate 74, a slag discharge port 75, and a clamping plate 76. The sweeping plate 71 is fixedly connected to the outer wall of the main shaft 5. By rotating the main shaft 5, the sweeping plate 71 can clean impurities. The bottom of the sweeping plate 71 is slidably connected to the sleeve 72. The outer wall of the main shaft 5 is rotatably connected to the sleeve 72. The outer wall of the sleeve 72 is fixedly connected to the circular screen 73. The bottom of the circular screen 73 is fixedly connected to the fixed plate 74. The fixed plate 74 is fixedly installed on the inner wall of the main body 2. The sewage entering through the sewage inlet 6 can filter out larger impurities on the circular screen 73. The bottom of the fixed plate 74 is fixedly installed to the slag discharge port 75. The slag discharge port 75 is fixedly installed on the outer wall of the main body 2. The outer wall of the slag discharge port 75 is slidably connected to the clamping plate 76. By pulling up the clamping plate 76, the impurities accumulated in the slag discharge port 75 can be cleaned.

[0026] Working principle: When wastewater needs to be treated, the wastewater enters the main body 2 through the sewage inlet 6. The operator starts the motor 3, which drives the rotating shaft 4 to rotate. The treated water permeates through the sand and gravel layer 8 to the top of the partition layer 91, and slowly flows through the screen cylinder 92 to the neutralization layer. The operator adds the appropriate proportion of chemicals through the chemical inlet 10. The main shaft 5 drives the stirring rod 97 to rotate, and the sliding column 98 at the top of the stirring rod 97 is rotated. The telescopic rod 95 elastically pulls the stirring rod 97 to squeeze it towards the partition layer 91. At the same time, the telescopic rod... 95, spring 96, and turntable 94 are rotated. Sliding column 98 slides on the outer surface of partition 91 and approaches protrusion 93. Sliding column 98 is pushed up by the inclined surface of protrusion 93. Telescopic rod 95 and spring 96 are stretched. Stirring rod 97 slides on slide groove 99. Sliding column 98 slides to the low inclined surface of protrusion 93. Spring 96 rebounds and pulls stirring rod 97 closer to turntable 94, so that stirring rod 97 can move up and down while being rotated by main shaft 5, so that the neutralization reaction of treated water is more complete.

[0027] When wastewater needs to be treated, the wastewater enters the main body 2 through the sewage inlet 6. The wastewater comes into contact with the surface of the circular screen 73 and flows to the lower layer through the mesh of the circular screen 73. Impurities are blocked on the surface of the circular screen 73 on the sleeve 72. The operator starts the motor 3 to drive the rotating shaft 4. The main shaft 5 drives the sweeping plate 71 to rotate on the surface of the circular screen 73 and the fixed plate 74. The sweeping plate 71 drives the impurities to rotate. When the impurities pass through the slag discharge port 75, they fall into the slag discharge port. The impurities are blocked and accumulated by the clamping plate 76. After the wastewater is treated, the clamping plate 76 can be pulled up to let the impurities flow into the garbage can, making cleaning very convenient.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
