Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a wastewater treatment device for a leather workshop. Background Art

[0002] The leather processing process will produce a large amount of wastewater containing animal hair, fine suspended matter, fiber, pulp and impurities. This wastewater must be treated before it can be discharged or reused.

[0003] Publication No. CN 213610137 U discloses a leather wastewater treatment system, which starts a first motor, and the first motor drives the first synchronous wheel and the rotating drum to rotate through the second synchronous wheel and the synchronous belt. The rotating drum drives the filter drum to rotate and makes the filter residue inside the filter drum interact with the scraper, so that the filter residue falls into the material guide drum through the feed port on the material guide drum. Then, by starting the second motor, the second motor drives the propeller to rotate through the output shaft and guides the filter residue into the waste box. At the same time, by starting the water pump, the water pump draws the cleaning liquid inside the cleaning box into the spray pipe through the guide pipe to increase the pressure and flushes the filter drum through the high-pressure nozzle, thereby achieving a simple, convenient and efficient filtering and impurity removal effect.

[0004] The above-mentioned prior art filters wastewater through a filter cartridge, and then when the filter cartridge rotates, a scraper scrapes the impurities on the filter cartridge into a material guide barrel, and then a propeller is used to discharge the impurities. However, the scraper is arranged at an upper position inside the filter cartridge, and the scraper can only scrape the impurities attached to the filter cartridge into the material guide barrel. As for some impurities that are not attached to the filter cartridge, they are always located at the bottom of the filter cartridge. When the filter cartridge rotates, the impurities will not rotate into the material guide barrel, resulting in incomplete cleaning of the impurities. In addition, limited impurities are attached to the filter cartridge and are difficult to be scraped off by the scraper, such as animal hair, paper fibers, etc., resulting in unsatisfactory cleaning effects of these impurities. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] In view of this, the purpose of the utility model is to propose a leather workshop wastewater treatment device. The technical problem to be solved is that some impurities that are not attached to the filter cartridge are always located at the bottom of the filter cartridge. When the filter cartridge rotates, the impurities will not rotate into the material guide barrel, resulting in incomplete impurity cleaning. Moreover, limited impurities are attached to the filter cartridge and are difficult to be scraped off by a scraper, such as animal hair, paper fibers, etc., resulting in unsatisfactory cleaning effect of these impurities.

[0007] (II) Technical solution

[0008] In order to achieve the above technical purpose, the utility model provides a leather workshop wastewater treatment device:

[0009] It includes a processing tank, a conical tube is fixed at the bottom of the processing tank and is connected to it, a connecting tube is fixed at the bottom of the conical tube and is connected to it, a feed tube is fixed on the connecting tube and is connected to it, a discharge tube is fixed at the middle of the processing tank and is connected to it, an annular sleeve is fixed at the inner wall of the processing tank, a conical filter cartridge is slidably connected in the annular sleeve, and the conical filter cartridge and the conical tube are connected, a water collecting tray is fixed at the top of the processing tank, a control component for controlling the spraying of cleaning water in the water collecting tray is arranged at the top of the processing tank, and a cleaning component for cleaning impurities on the conical filter cartridge is arranged on the processing tank.

[0010] Preferably, a protrusion is fixed on the top of the conical filter cartridge, and two L-shaped rods are symmetrically fixed on the outer side of the protrusion. The L-shaped rods penetrate the processing tank and are slidably connected to the processing tank.

[0011] Preferably, the cleaning assembly includes a placement plate fixed to the top of the processing tank, a motor is fixedly installed on the top of the placement plate, a connecting shaft is fixed to the output end of the motor, an eccentric wheel is fixed to one end of the connecting shaft, and a connecting plate is commonly fixed to one end of the two L-shaped rods, and the eccentric wheel can drive the connecting plate to move when it rotates.

[0012] Preferably, a partition is fixed on the outside of the L-shaped rod, and a spring is sleeved on the outside of the L-shaped rod, with one end of the spring abutting against the partition, and the other end of the spring abutting against the inner wall of the processing tank.

[0013] Preferably, the control component comprises a baffle plate which rotates in the water collecting tray, a plurality of first slots are formed at equal intervals at the bottom of the water collecting tray, and a plurality of second slots corresponding to the first slots are formed in the baffle plate.

[0014] Preferably, a rotating rod is fixed to the top of the baffle, and the rotating rod passes through the processing tank and is rotatably connected to the processing tank, a driven gear is fixed to one end of the rotating rod extending outside the processing tank, a rotating shaft is rotatably connected to the top of the processing tank, and a driving gear meshing with the driven gear is fixed to the outside of the rotating shaft.

[0015] Preferably, a toggle rod is fixed to the top of the rotating shaft, a feeding trough connected to the water collecting tray is provided on the top of the processing tank, and a threaded cover is threadedly connected to the bottom of the connecting pipe.

[0016] It can be seen from the above technical solutions that the present application has the following beneficial effects:

[0017] 1: Turn the toggle lever to drive the rotating shaft and the driving gear to rotate. When the driving gear rotates, it drives the driven gear, the rotating rod and the baffle to rotate. When the second notch coincides with the first notch, the cleaning water in the water collecting tray is discharged from the second notch and the first notch and sprinkled onto the conical filter cartridge to flush the impurities on the conical filter cartridge. The flushed impurities are flushed into the conical pipe and the connecting pipe.

[0018] 2: Start the motor to drive the eccentric wheel to rotate. When the eccentric wheel rotates, it squeezes the connecting plate and drives the connecting plate, L-shaped rod and conical filter cartridge to move upward. When the eccentric wheel no longer squeezes the connecting plate, the L-shaped rod and conical filter cartridge are driven downward under the spring rebound force, causing the conical filter cartridge and the bottom of the treatment tank to collide and vibrate, so that the impurities on the conical filter cartridge are shaken off into the conical pipe and connecting pipe. Then open the threaded cover to discharge the impurities.

[0019] 3: Through the setting of the toggle rod, when the toggle rod and the connecting plate are perpendicular, the toggle rod exerts pressure on the connecting plate, thereby preventing the impact force on the conical filter cartridge when wastewater rushes into the conical filter cartridge and driving the conical filter cartridge to move upward. When cleaning impurities in the conical filter cartridge, the toggle rod is moved away from the connecting plate, and when the toggle rod rotates, the driving gear, the driven gear, the rotating rod, and the baffle are driven to rotate, so that the second notch and the first notch can be linked to overlap, so that the cleaning water in the water collection tray can wash away the impurities on the conical filter cartridge.

[0028] Reference Figure 1-5 :

[0029] The utility model provides a leather workshop wastewater treatment device, comprising a treatment tank 1, a conical pipe 2 is fixed and connected to the bottom of the treatment tank 1, a connecting pipe 3 is fixed and connected to the bottom of the conical pipe 2, a feed pipe 4 is fixed and connected to the connecting pipe 3, a discharge pipe 5 is fixed and connected to the middle of the treatment tank 1, an annular sleeve 6 is fixed to the inner wall of the treatment tank 1, a conical filter cartridge 7 is slidably connected in the annular sleeve 6, and the conical filter cartridge 7 is connected to the conical pipe 2, a water collecting tray 8 is fixed to the top of the treatment tank 1, a control component for controlling the spraying of cleaning water in the water collecting tray 8 is arranged on the top of the treatment tank 1, and a cleaning component for cleaning impurities on the conical filter cartridge 7 is arranged on the treatment tank 1.

[0030] It should be noted that when the wastewater from the leather production workshop is input from the feed pipe 4 into the connecting pipe 3, and then transported from the connecting pipe 3 to the conical pipe 2, and then transported to the conical filter cartridge 7, the conical filter cartridge 7 filters the wastewater, and the filtered wastewater is transported to the treatment tank 1 and then discharged from the discharge pipe 5.

[0031] In addition, the control component includes a baffle 15 rotating in the water collecting tray 8, a plurality of first slots 14 are opened at equal intervals at the bottom of the water collecting tray 8, a plurality of second slots 16 corresponding to the first slots 14 are opened in the baffle 15, a rotating rod 17 is fixed to the top of the baffle 15, and the rotating rod 17 passes through the treatment tank 1 and is rotatably connected to the treatment tank 1, a driven gear 18 is fixed to one end of the rotating rod 17 extending outside the treatment tank 1, a rotating shaft 19 is rotatably connected to the top of the treatment tank 1, and a driving gear 21 meshing with the driven gear 18 is fixed to the outside of the rotating shaft 19, a toggle rod 20 is fixed to the top of the rotating shaft 19, a feeding trough 22 connected to the water collecting tray 8 is opened at the top of the treatment tank 1, and a threaded cover 27 is threadedly connected to the bottom of the connecting pipe 3.

[0032] It should be noted that when there are many impurities on the conical filter cartridge 7 and the conical filter cartridge 7 needs to be cleaned, the toggle lever 20 is first rotated so that the toggle lever 20 no longer presses the connecting plate 11. When the toggle lever 20 rotates, the rotating shaft 19 and the driving gear 21 are driven to rotate. When the driving gear 21 rotates, the driven gear 18 is driven to rotate. When the driven gear 18 rotates, the rotating rod 17 and the baffle 15 are driven to rotate, so that the second notch 16 and the first notch 14 coincide with each other, that is, the cleaning water in the water collecting tray 8 is discharged from the second notch 16 and the first notch 14, and sprinkled onto the conical filter cartridge 7, so that the impurities on the conical filter cartridge 7 are washed, and the washed impurities are washed into the conical pipe 2 and the connecting pipe 3.

[0033] In addition, a protrusion 9 is fixed to the top of the conical filter cartridge 7, and two L-shaped rods 10 are symmetrically fixed on the outside of the protrusion 9. The L-shaped rod 10 penetrates the treatment tank 1 and is slidably connected to the treatment tank 1.

[0034] It should be noted that when cleaning the impurities on the conical filter cartridge 7, the motor 24 is started to drive the eccentric wheel 25 to rotate. When the eccentric wheel 25 rotates, it squeezes the connecting plate 11 and drives the connecting plate 11 to move upward, thereby driving the L-shaped rod 10 and the conical filter cartridge 7 to move upward, so that the spring 13 is compressed, and the conical filter cartridge 7 slides in the annular sleeve 6. When the eccentric wheel 25 no longer squeezes the connecting plate 11, the L-shaped rod 10 and the conical filter cartridge 7 are driven downward under the rebound force of the spring 13, so that the conical filter cartridge 7 collides with the bottom of the processing tank 1, thereby causing the conical filter cartridge 7 to vibrate, so that the impurities on the conical filter cartridge 7 are shaken off into the conical pipe 2 and the connecting pipe 3, and then the threaded cover 27 is opened to discharge the impurities.
