AI Technical Summary
The existing sand filters lack high-temperature disinfection structure when treating tin-removing wastewater, resulting in poor sterilization effect. After long-term use, the filtration speed of the sand layer is reduced due to the compaction of the water body pressure.
The tank body of the sand filter is installed with heating coils and thermal conductor plates for wastewater heating. The drive motor drives the rotating rod and the connecting rod to achieve loosening of the sand layer, ensuring filtration speed and cleanliness.
It improves the sterilization and disinfection effect of wastewater, prevents bacteria and viruses from being taken away, enhances purification and cleanliness, and prevents the filtration speed from being reduced by loosening the sand layer.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of sand filters, in particular to a sand filter for treating tin stripping wastewater. Background Art
[0002] Tin stripping wastewater refers to wastewater containing toxic and harmful substances such as lead, cyanide, acid, and alkali generated by industries such as electroplating and printed circuit boards. It is characterized by high concentration, high toxicity, and high volatility. If discharged at will, it will seriously pollute the environment and threaten ecological security and human health. When conducting harmless treatment of tin stripping wastewater, a sand filter is required to filter out the impurity particles in the tin stripping wastewater.
[0003] At present, a Chinese utility model with the announcement number CN212187938U discloses a sand filter with an efficient backwash structure, including a sand filter body, a sealing plate, a connecting block, a sleeve block and a handle, a buffer mechanism is arranged between the connecting block and the sleeve block, the buffer mechanism includes a slide bar, a slider, a first spring, a first limit block, a rotating block, a slide groove and a second limit block, the slide bar is fixed on the connecting block inside the sleeve block, the slide bar is sleeved with a slider, the slide bar is sleeved with a first spring, and the two ends of the first spring are respectively fixed on the slider and the slide bar. The utility model prevents the staff from retreating due to excessive force, so that after the sealing plate is opened, the opening force can be buffered, which solves the problem that the existing sealing cover is inconvenient to open, improves the safety and convenience of the staff during operation, thereby protecting the hands of the staff, and solves the problem that the handle of the existing sand filter is relatively uncomfortable when held.
[0004] To sum up, although the sand filter has the function of backwashing, there are still certain problems when using it. For example, the sand filter lacks a structure for high-temperature disinfection of wastewater. Although carbon sand is generally installed inside the sand filter, it has a certain effect of absorbing odors, harmful gases and chemicals. However, carbon sand cannot directly remove bacteria and viruses in the water. As the wastewater flows, some bacteria and viruses adsorbed on the carbon sand can easily move away from the carbon sand along the water body, resulting in poor sterilization and disinfection effects. At the same time, the sand filter lacks a flipping structure. After the sand filter has been working for a long time, the internal sand and gravel layers will be compacted against each other due to the pressure of the water body, resulting in a smaller water flow rate when the wastewater is discharged, resulting in a lower filtration speed. Utility Model Content
[0005] The utility model aims to provide a sand filter for treating tin stripping wastewater, which has the advantages of good sterilization effect and anti-compaction.
[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a sand filter for treating tin stripping wastewater, comprising a tank body, a controller is installed on the surface of the tank body through a fixing piece, a tank cover is bolted on the top of the tank body, a sealing ring is clamped between the tank cover and the tank body, a groove is opened inside the tank body, a heating coil is arranged inside the groove, a heat conducting plate is installed inside the groove, a support plate is slidably connected to the inside of the tank body, a connecting rod is rotatably connected to the bottom of the tank body through a bearing, a first rotating disk is symmetrically bolted to the bottom of the support plate, one end of the connecting rod penetrates into the interior of the tank body and is fixedly sleeved with a second rotating disk, a support seat is symmetrically bolted to the surface of the tank body, a rotating rod is symmetrically rotatably connected between the two support seats through a bearing, a driving motor is fixedly installed on the support seat through a fixing piece on the surface of the tank body, a bevel gear is fixedly sleeved on the surface of the rotating rod and one end of the connecting rod, and the two bevel gears are meshed.
[0007] By adopting the above technical scheme, the utility model has a groove opened inside the tank body, and a heating coil is installed inside the groove. In combination with the use of a heat conduction plate, when the sand filter filters and purifies wastewater, the wastewater can be heated to improve the effect of sterilization and disinfection, and the bacteria and viruses adsorbed by the carbon sand layer can be prevented from being carried away by the water flow, resulting in a deterioration in the effect of sterilization and disinfection, thereby improving the cleanliness of wastewater purification. Bevel gears are installed on the rotating rod and the connecting rod. When the driving motor is started, the rotating rod can be driven to rotate, thereby driving the connecting rod to rotate, and the connecting rod drives the second rotating disk to rotate.

[0012] The utility model is further configured as follows: the first rotating disk and the second rotating disk have the same size, and the first rotating disk and the second rotating disk fit together.
[0013] The above technical solution is adopted to facilitate lifting the first rotating disk when the second rotating disk rotates.
[0014] The utility model is further configured as follows: one end of the two rotating rods penetrates through the other side of the supporting seat and is fixedly sleeved with transmission gears that cooperate with each other.

[0017] The above technical solution is adopted to facilitate the wastewater to enter the sand filter and to facilitate the discharge of backwash water.
[0018] The utility model is further configured as follows: the bottom of the tank cover is connected with a drain pipe, the surface of the drain pipe is connected with a backwash water inlet pipe, and valves are installed on the surfaces of the drain pipe and the backwash water inlet pipe.
[0019] The above technical solution is adopted to facilitate the discharge of wastewater and the entry of backwash water.
[0020] The utility model is further configured as follows: a sliding rod which is slidably connected to the tank body and is bolted to the bottom of the support plate, and the number of the sliding rods is two.
[0021] The above technical solution is adopted to slide and limit the support plate.
