Description

Technical Field

[0001] This utility model belongs to the field of alloy cast iron technology and relates to wastewater recycling, specifically a device for recycling wastewater from alloy cast iron production. Background Technology

[0002] The production of alloy cast iron generates a large amount of wastewater containing harmful substances such as heavy metals, oil, and chemical additives. Without proper treatment and recycling, this wastewater will cause serious environmental pollution. Wastewater recycling systems for alloy cast iron production typically include the following key components: a pretreatment system to remove large suspended solids, oil, and other impurities, usually using equipment such as screens, sedimentation tanks, or oil-water separators; physicochemical treatment to further remove fine suspended solids and dissolved pollutants through flocculation, sedimentation, and filtration; commonly used equipment includes coagulant dosing devices, sedimentation tanks, and filters; and biological treatment, which utilizes biological technologies such as activated sludge processes and biofilm processes to remove organic pollutants through the metabolic activity of microorganisms if the wastewater has a high organic content. By combining these technologies and equipment, wastewater recycling systems for alloy cast iron production can effectively reduce wastewater discharge, lower production costs, protect the environment, and meet the requirements of sustainable development.

[0003] However, some existing wastewater recycling devices are not easy to remove impurities during pretreatment, which makes the devices prone to clogging during the treatment process. This leads to reduced equipment efficiency, the need for frequent cleaning and maintenance, and increased operating costs and manpower. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a device for recycling wastewater from alloy cast iron production. The technical problem this utility model aims to solve is that it is difficult to remove impurities, which leads to the device being easily clogged by impurities during the water treatment process, resulting in reduced equipment operating efficiency, the need for frequent cleaning and maintenance, and increased operating costs and manpower.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for recycling wastewater from alloy cast iron production includes a housing. A filter plate is fixedly connected inside the housing, and a filter disc is rotatably connected inside the filter plate. Two filter chambers are symmetrically arranged on one side of the filter disc. A filter port is provided on the surface of the filter plate near one of the filter chambers. A rotating mechanism for rotating the filter disc is provided at the top of the housing. Sliding grooves are provided on the surface of the filter disc near both filter chambers, and the grooves cooperate with the filter chambers. A sealing mechanism for sealing the filter chambers is provided inside each of the two sliding grooves. An inspection port is provided at the top of the housing near the filter plate, and a closing mechanism for closing the inspection port is provided at the top of the inspection port. The filter disc design ensures that impurities can be quickly removed.

[0007] As a further embodiment of this utility model, the rotating mechanism includes a first gear, which is rotatably connected to one side of the housing. A second gear is fitted on the surface of the first gear away from the filter disc. A motor is fixedly connected to one side of the second gear and is fixedly connected to the top of the housing. The surface of the filter disc near the first gear has multiple toothed grooves, which are evenly arranged in a ring. Each of the toothed grooves is fitted with the first gear. The arrangement of the toothed grooves allows the filter disc to rotate.

[0008] As a further embodiment of this utility model, the sealing mechanism includes multiple limiting rods, each of which is fixedly connected to one side of the inner side of the slide groove. A baffle is slidably fitted onto the surface of each of the multiple limiting rods, and the baffle is slidably connected to the inside of the slide groove. The baffle and the filter plate are mutually coordinated. A second spring is fitted onto the surface of each of the multiple limiting rods, with one end of each second spring fixedly connected to one side of the baffle and the other end fixedly connected to one side of the inner side of the slide groove. The baffle design prevents leakage.

[0009] As a further embodiment of this utility model, the closing mechanism includes a cover plate, which is slidably connected to the top of the inspection port. Two support columns are slidably connected to both sides of the cover plate. The same clamping plate is fixedly connected to the surface of the two support columns near the housing, and the two clamping plates are mutually cooperating with the housing. A first spring is sleeved on the surface of each of the two support columns. One end of each of the two first springs is fixedly connected to one side of the clamping plate, and the other end of each of the two first springs is fixedly connected to one side of the inside of the cover plate. An inlet pipe is provided on the surface of the housing near the inspection port, and an outlet pipe is provided on the surface of the housing away from the inlet pipe. The inspection port can be closed by the cover plate.

[0010] The beneficial effects of this utility model are as follows:

[0011] This invention employs a technology that uses a filter disc to rotate impurities, ensuring rapid removal of these impurities. This effectively solves the problem of impurity blockage during water treatment, which leads to reduced equipment efficiency, frequent cleaning and maintenance, and increased operating costs and manpower. A motor is installed at the top of the casing. When impurities need to be cleaned, the motor is started. A second gear is installed on the motor's output shaft, which is connected to the filter disc via the first gear. When the motor starts, the filter disc rotates, engaging another filter chamber with the filter outlet. Because the bottom of the filter plate is open, the opening of the filter chamber engages with the filter plate as the filter disc rotates, thus discharging impurities from the filter chamber.

A sliding groove 301 is opened on the surface of the filter disc 203 near the two filter chambers 204, and the sliding groove 301 is configured to cooperate with the filter chambers 204. A sealing mechanism for sealing the filter chambers 204 is provided inside the two sliding grooves 301. An inspection port 103 is opened on the top of the housing 1 near the filter plate 201. A closing mechanism for closing the inspection port 103 is provided on the top of the inspection port 103. The filter disc 203 ensures that impurities can be quickly removed.

[0020] Preferably, the rotating mechanism includes a first gear 206, which is rotatably connected to one side of the housing 1. A second gear 207 is fitted on the surface of the first gear 206 away from the filter disc 203. A motor 2 is fixedly connected to one side of the second gear 207 and is fixedly connected to the top of the housing 1. The surface of the filter disc 203 near the first gear 206 has multiple toothed grooves 205, which are evenly arranged in a ring. All the toothed grooves 205 are fitted with the first gear 206. The toothed grooves 205 allow the filter disc 203 to rotate.

[0021] Preferably, the sealing mechanism includes multiple limiting rods 302, each fixedly connected to one side of the inside of the slide groove 301. A baffle 3 is slidably fitted onto the surface of each limiting rod 302. The baffle 3 is slidably connected to the inside of the slide groove 301 and is configured to cooperate with the filter plate 201. A second spring 303 is fitted onto the surface of each limiting rod 302. One end of each second spring 303 is fixedly connected to one side of the baffle 3. The second spring 303 ensures that the baffle 3 can be in close contact with the filter plate 201. The other end of each second spring 303 is fixedly connected to one side of the inside of the slide groove 301. The baffle 3 prevents leakage.

[0022] Preferably, the closing mechanism includes a cover plate 104, which is slidably connected to the top of the inspection port 103. Two support columns 105 are slidably connected to both sides of the cover plate 104. The same clamping plate 106 is fixedly connected to the surface of the two support columns 105 near the housing 1, and the two clamping plates 106 are mutually cooperating with the housing 1. A first spring 107 is sleeved on the surface of the two support columns 105. One end of the two first springs 107 is fixedly connected to one side of the clamping plate 106, and the other end of the two first springs 107 is fixedly connected to one side of the inside of the cover plate 104.

A filter plate 201 is installed inside the housing 1, and a filter disc 203 is installed inside the filter plate 201. Two filter chambers 204 are opened on one side of the filter disc 203, so impurities in the wastewater can be filtered through the filter chambers 204. However, only one filter port 202 is opened on one side of the filter plate 201, so only one of the two filter chambers 204 can be used at a time. A motor 2 is installed on the top of the housing 1. When impurities need to be cleaned, motor 2 can be started. A second gear 207 is installed on the output shaft of motor 2. The second gear 207 is connected to filter disc 203 through first gear 206. When motor 2 is started, filter disc 203 can be rotated, thereby enabling another filter chamber 204 to engage with filter port 202. Because the bottom of filter plate 201 is open, as filter disc 203 continues to rotate, the opening of filter chamber 204 will engage with filter plate 201, thereby discharging impurities from filter chamber 204.
