Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, and particularly relates to a weak acid wastewater treatment device. Background Technique

[0002] A large amount of residual oil, leftovers, and waste water collected from fuel oil spraying overflow during the processes of washing, cooking, roasting, and stir-frying contains a large amount of organic matter, waste residue, colloid, and macromolecular substances (synthetic detergents, soaps, oils, etc.), as well as various nutrients (ammonium salts, phosphates, nitrates, etc.), and is extremely prone to corruption and odor. If the catering wastewater is directly discharged without treatment or improper treatment, it is easy to cause oxygen deficiency or even odor in the environmental water area when discharged into the environmental water area;

[0003] According to a disclosed catering wastewater treatment device and wastewater treatment method (CN 106977031 A), it includes an air flotation tank, a filtering mechanism, and a disinfection tank. The air flotation tank includes a tank main body, and the tank main body includes a bubble generating device and a slag treatment mechanism connected in sequence. The filtering mechanism includes a filtering main body, and a filter membrane assembly is arranged inside the filtering main body;

[0004] However, in the above design, it is difficult to avoid the waste in the wastewater from blocking the filter disc during the filtering process through the cooperation of components such as the air flotation tank and the filtering mechanism, resulting in the abnormal operation of the filtering device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a weak acid wastewater treatment device. When the blocking block presses against the round bar, the filter disc slidingly connected to the inner wall of the closed barrel slides up and down, thereby avoiding the waste in the weak acid wastewater from blocking the filter disc and enabling the filtering device to operate normally, solving the existing problems.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a weak acid wastewater treatment device, including a fixing plate and a closed barrel. The closed barrel is fixedly connected to the top of the fixing plate. A funnel is arranged on the circumferential surface of the fixing plate. A filtering device is arranged inside the closed barrel; the filtering device includes a motor. The motor is arranged on the top of the closed barrel. The end of the output shaft of the motor is fixedly connected to a rotating rod. The inner wall of the closed barrel is slidingly connected to a filter disc.

[0008] Furthermore, a disc is fixedly connected to the circumferential surface of the rotating rod. A blocking block is fixedly connected to the top of the disc. A round bar is fixedly connected to the bottom of the filter disc. A water outlet is opened on the inner wall of the closed barrel. A water pump is arranged on the inner wall of the water outlet. Such a design is beneficial for the filter disc to filter the waste in the weak acid wastewater when the weak acid wastewater enters the closed barrel.

[0009] Furthermore, the bottom of the filter plate is located above the bottom of the disc. The side cross-section of the round bar is circular, and there is no connection relationship between the filter plate and the rotating rod. Such a design is beneficial for the round bar to rotate, causing the material blocking plate to rotate under the thrust and closing the discharge port.

[0010] Furthermore, a purification device is provided on the circumferential surface of the closed barrel. The purification device includes a discharge box. The bottom of the discharge box is fixedly penetrated through the inner wall of the closed barrel. An inlet is provided on the inner wall of the discharge box, and an outlet is provided on the inner wall of the discharge box. The bottom of the discharge box is fixedly connected with a support plate. Such a design is beneficial for the staff to place alum, and the alum can flow into the closed barrel through the outlet.

[0011] Furthermore, a rotating round shaft is hinged on the inner wall of the inlet. A partition plate is fixedly connected to the circumferential surface of the rotating round shaft. A handle is fixedly connected to the top of the partition plate. A rotating shaft is hinged on the inner wall of the outlet. A material blocking plate is fixedly connected to the circumferential surface of the rotating shaft. A push rod is fixedly connected to the circumferential surface of the rotating rod. A first torsion spring is fixedly connected to the circumferential surface of the rotating round shaft, and a second torsion spring is fixedly connected to the circumferential surface of the rotating shaft. Such a design is beneficial for the torsion of the second torsion spring to reset the material blocking plate when alum enters the closed barrel.

[0012] Furthermore, the outlet is located below the inlet, and the side cross-section of the support plate is trapezoidal. Such a design is beneficial for the staff to smoothly put alum into the discharge box.

[0013] Furthermore, the inlet is located above the outlet. There are several blocking blocks, which are arranged in a circumferential array on the top of the disc. Such a design is beneficial for the rotating rod to rotate clockwise, driving the disc to rotate clockwise. While the blocking blocks rotate, they squeeze the round bar, causing the filter plate to slide up and down, so that the waste in the weak acid wastewater cannot block the filter plate.

[0014] The utility model has the following beneficial effects:

[0015] Through the mutual cooperation of components such as the filter plate, disc, blocking block, and water pump, the utility model realizes that when the blocking block squeezes the round bar, the filter plate slidingly connected to the inner wall of the closed barrel slides up and down, thereby preventing the waste in the weak acid wastewater from blocking the filter plate, enabling the filter device to operate normally, giving full play to the role of the filter plate, improving work efficiency, and accelerating the work progress of the staff.

[0016] Through the mutual cooperation of components such as the discharge box, inlet, material blocking plate, and push rod, the utility model realizes that when the push rod passes by the material blocking plate, the material blocking plate loses the thrust, thereby facilitating the torsion of the second torsion spring to achieve the reset effect, and thus achieving the indirect flow of alum into the closed barrel, fully purifying the weak acid wastewater.

[0017] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0027] Please refer to Figures 1-5, the present utility model is a weak acid wastewater treatment device, including a fixing plate 1 and a closed barrel 2. The closed barrel 2 is fixedly connected to the top of the fixing plate 1. A funnel 3 is arranged on the circumferential surface of the fixing plate 1, and a filtering device 4 is arranged inside the closed barrel 2; the filtering device 4 includes a motor 41, the motor 41 is arranged on the top of the closed barrel 2, the end of the output shaft of the motor 41 is fixedly connected to a rotating rod 42, and the inner wall of the closed barrel 2 is slidably connected with a filtering disc 43.

[0028] A disc 44 is fixedly connected to the circumferential surface of the rotating rod 42, a blocking block 45 is fixedly connected to the top of the disc 44, a round bar 46 is fixedly connected to the bottom of the filtering disc 43, a water outlet 47 is opened on the inner wall of the closed barrel 2, and a water pump 48 is arranged on the inner wall of the water outlet 47. Such a design is beneficial for the filtering disc 43 to filter the waste in the weak acid wastewater when the weak acid wastewater enters the closed barrel 2.

[0029] The bottom of the filtering disc 43 is located above the bottom of the disc 44. The side cross-section of the round bar 46 is circular, and there is no connection relationship between the filtering disc 43 and the rotating rod 42. Such a design is beneficial for the round bar 46 to rotate, so that the blocking plate 59 is pushed to rotate and close the discharge port 53.

[0030] A purification device 5 is arranged on the circumferential surface of the closed barrel 2. The purification device 5 includes a discharge box 51. The bottom of the discharge box 51 is fixedly penetrated through the inner wall of the closed barrel 2. A feed inlet 52 is opened on the inner wall of the discharge box 51, a discharge port 53 is opened on the inner wall of the discharge box 51, and a support plate 54 is fixedly connected to the bottom of the discharge box 51. Such a design is beneficial for the staff to place alum, and the alum can flow into the closed barrel 2 through the discharge port 53.

[0031] A rotating round shaft 55 is hinged on the inner wall of the feed inlet 52. A partition plate 56 is fixedly connected to the circumferential surface of the rotating round shaft 55. A handle 57 is fixedly connected to the top of the partition plate 56. A rotating shaft 58 is hinged on the inner wall of the discharge port 53. A blocking plate 59 is fixedly connected to the circumferential surface of the rotating shaft 58. A push rod 510 is fixedly connected to the circumferential surface of the rotating rod 42. A first torsion spring 511 is fixedly connected to the circumferential surface of the rotating round shaft 55. A second torsion spring 512 is fixedly connected to the circumferential surface of the rotating shaft 58. Such a design is beneficial for the second torsion spring 512 to make the blocking plate 59 reset when the alum enters the closed barrel 2.

[0032] The discharge port 53 is located below the feed inlet 52. The side cross-section of the support plate 54 is trapezoidal. Such a design is beneficial for the staff to smoothly put the alum into the discharge box 51.

[0033] The feed inlet 52 is located above the discharge outlet 53. A number of blocking blocks 45 are provided and are arranged in a circumferential array on the top of the disc 44. Such a design is beneficial for driving the disc 44 to rotate clockwise when the rotating rod 42 rotates clockwise. While the blocking block 45 rotates accordingly, it squeezes the round bar 46, causing the filter disc 43 to slide up and down, so that the waste in the weak acid wastewater cannot block the filter disc 43.

[0034] A specific application of this embodiment is as follows: First, the staff introduces the weak acid wastewater into the closed barrel 2. When the power is started, the motor 41 starts, and the rotating rod 42 fixed at the end of the motor output shaft rotates clockwise. When the weak acid wastewater enters the closed barrel 2, the filter disc 43 filters the waste in the weak acid wastewater. To prevent the waste in the weak acid wastewater from blocking the filter disc 43, the disc 44 fixed on the circumferential surface of the rotating rod 42 rotates with the clockwise rotation of the rotating rod 42. When the disc 44 rotates clockwise, it drives the blocking block 45 fixed on the top of the disc 44 to rotate clockwise. While the blocking block 45 rotates clockwise, it squeezes the round bar 46 fixed at the bottom of the filter disc 43, causing the filter disc 43 slidably connected to the inner wall of the closed barrel 2 to slide up and down, thereby preventing the waste in the weak acid wastewater from blocking the filter disc 42 and enabling the filtering device 4 to operate normally.

[0035] In the filtering device 4, when the waste of the weak acid wastewater is filtered, it still needs to be continuously purified. The staff puts alum into the discharge box 51, and the alum will flow into the closed barrel 2 along the discharge outlet 53. When the rotating rod 42 rotates clockwise, the push rod 510 fixed on the circumferential surface of the rotating rod 42 also rotates accordingly. When the push rod 510 rotates clockwise, it contacts the material blocking plate 59. When the push rod 510 contacts the material blocking plate 59, the material blocking plate 59 is pushed to rotate clockwise. When the push rod 510 passes the material blocking plate 59, the material blocking plate 59 loses the thrust, so as to facilitate the torsion of the second torsion spring 512 to achieve the reset effect, thereby achieving the intermittent inflow of alum into the closed barrel and fully purifying the weak acid wastewater.
