Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater treatment device for the production of packaging paper bags. Background Technology

[0002] In the production of packaging paper bags, some paper processing steps are required. The wastewater generated in these processes often contains a large amount of organic matter and suspended solids. For environmental protection reasons, this wastewater cannot be discharged directly and therefore needs to be treated. There are many wastewater treatment devices of various sizes in the existing technology.

[0003] For example, the national authorized patent number "CN 208916988 U" "A wastewater treatment device for a paper mill" states that "the interior of the sedimentation tank is provided with a first filter screen and a second filter screen from top to bottom, and the pore size of the first filter screen is larger than that of the second filter screen." The above patent is similar to a small wastewater treatment device commonly found in the prior art. As the sedimentation tank is used, a large amount of impurities will accumulate on the filter screen. However, the top of the sedimentation tank in the above device is closed, and the filter screen is installed inside the sedimentation tank, making it difficult to clean the impurities on the filter screen. Over time, this will affect the use of the device. In view of this, in-depth research was conducted to address the above problems, which led to this case. Utility Model Content

[0004] The purpose of this utility model is to provide a wastewater treatment device for the production of packaging paper bags, so as to solve the problem of inconvenience in cleaning the filter screen mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment device for packaging paper bag production, comprising a base, two sedimentation tanks installed on one side of the top of the base, and two bottom cylinders installed on the other side of the top of the base. An installation cylinder is provided above each of the two bottom cylinders, and a cover is provided above each of the two installation cylinders. Filter plates are fixed to the inner walls of each of the two installation cylinders. Inlet pipes are embedded in the tops of the two covers. Four support rods are provided on the outer sides of the two bottom cylinders. The bottom ends of the support rods are fixed to the top of the base, and an installation platform is fixed to the top of the support rods. Multiple electric telescopic rods are installed on the top of the installation platform, and the output ends of the electric telescopic rods are fixed to the top of the covers. A wastewater pipe is provided above the installation platform, and a three-way regulating valve is installed at the output end of the wastewater pipe. Two inlet pipes are respectively installed at the two output ends of the three-way regulating valve, and flexible hoses are installed at the output ends of the two inlet pipes. The bottom ends of the two flexible hoses are respectively connected to the top ends of the two inlet pipes.

[0006] Preferably, two buffer plates are installed alternately on the inner wall of the cover, and the buffer plates are both inclined at a 15° angle.

[0007] Preferably, the bottom end of the cover extends into the interior of the mounting cylinder, and the bottom end of the mounting cylinder extends into the interior of the bottom cylinder.

[0008] Preferably, a water pump is provided on one side of the bottom cylinder, and the bottom end of the water pump is connected to the top end of the base. A water pump is installed at the input end of the water pump, and one end of the water pump extends to the bottom of the bottom cylinder. A water delivery pipe is installed at the output end of the water pump, and one end of the water delivery pipe extends to the top of the sedimentation tank.

[0009] Preferably, two sludge pumps are installed on one side of the top of the base, and each sludge pump has a drain pipe installed at its output end and a suction pipe installed at its input end, with one end of each suction pipe extending into the interior of the sedimentation tank.

[0010] Preferably, a drive motor is installed at the top center of the sedimentation tank, and the output end of the drive motor extends into the interior of the sedimentation tank and is equipped with a stirring paddle.

[0011] Preferably, two feeding hoppers are installed on one side of the top of the sedimentation tank, and the bottom of each feeding hopper extends into the interior of the sedimentation tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The bottom cylinder, mounting cylinder, and cover are assembled to form a closed structure, which can be used for filtration with filter plates. During normal operation, since the liquid inside the sedimentation tank needs time to settle, the two filter plates can be used alternately. When there are more impurities on the top of a filter plate, the corresponding electric telescopic rod can be activated to lift the corresponding cover when it is not in use, so that the filter plate is exposed and it is convenient for the staff to clean the upper surface of the filter plate. Alternatively, the mounting cylinder can be removed from the bottom cylinder for careful cleaning. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Please refer to Figure 1-3 A wastewater treatment device for packaging paper bag production includes a base 12. Two sedimentation tanks 20 are installed on one side of the top of the base 12, and two bottom cylinders 11 are installed on the other side of the top of the base 12. An installation cylinder 10 is installed above each of the two bottom cylinders 11, and a cover 8 is installed above each of the two installation cylinders 10. Filter plates 9 are fixed to the inner walls of each of the two installation cylinders 10. An inlet pipe 6 is embedded in the top of each of the two covers 8. Four support rods 5 are installed on the outer sides of the two bottom cylinders 11, and the bottom ends of the support rods 5 are connected to the base 12. The top of the support rod 5 is fixed to the top of the cover 8, and the top of the support rod 5 is fixed to the top of the cover 8. Multiple electric telescopic rods 3 are installed on the top of the support rod 5, and the output end of the electric telescopic rod 3 is fixed to the top of the cover 8. A wastewater pipe 23 is installed above the support rod 4, and a three-way regulating valve pipe 24 is installed at the output end of the wastewater pipe 23. Two water inlet pipes 1 are installed at the two output ends of the three-way regulating valve pipe 24, and hoses 2 are installed at the output ends of the two water inlet pipes 1. The bottom ends of the two hoses 2 are connected to the top ends of the two liquid inlet pipes 6 respectively.

[0020] The bottom end of the cover 8 extends into the interior of the mounting cylinder 10, and the bottom end of the mounting cylinder 10 extends into the interior of the bottom cylinder 11;

[0021] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, when the device is in use, wastewater is guided to wastewater pipe 23. At this time, the three-way regulating valve pipe 24 can control the opening and closing of the valve, so that wastewater pipe 23 is connected to one of the inlet pipes 1. In this way, wastewater can be sent to the corresponding liquid inlet pipe 6 through the hose 2. The bottom cylinder 11, the mounting cylinder 10 and the cover 8 are assembled to form a closed space. Wastewater is discharged into the space, and the filter plate 9 performs preliminary filtration of the wastewater. This allows impurities to remain above the filter plate 9, and subsequent wastewater can be sent to the sedimentation tank 20 for chemical reaction and sedimentation. When there is enough wastewater in one of the sedimentation tanks 20, the wastewater can be guided to the inlet pipe 1 of another location by controlling the three-way regulating valve pipe 24 to avoid delaying the work. At the same time, if there are many impurities above the filter plate 9 and it is not currently involved in wastewater treatment, the electric telescopic rod 3 can be activated to lift the cover 8. In this way, the top of the mounting cylinder 10 is not obstructed or restricted, and the top of the filter plate 9 can be cleaned directly. Alternatively, the mounting cylinder 10 can be removed to clean the filter plate 9 carefully.

[0022] Two buffer plates 7 are installed alternately on the inner wall of the cover 8, and the buffer plates 7 are both inclined at a 15° angle.

[0023] Specifically, such as Figure 1 As shown, the buffer plate 7 can buffer the wastewater sent from the inlet pipe 6, so that the wastewater can reach the filter plate 9 at a lower speed, ensuring the filtration effect.

[0024] A water pump 14 is provided on one side of the bottom cylinder 11, and the bottom end of the water pump 14 is connected to the top end of the base 12. A water pump pipe 13 is installed at the input end of the water pump 14, and one end of the water pump pipe 13 extends to the bottom of the bottom cylinder 11. A water delivery pipe 15 is installed at the output end of the water pump 14, and one end of the water delivery pipe 15 extends to the top of the sedimentation tank 20.

[0025] Specifically, such as Figure 1 and Figure 3 As shown, after the wastewater completes the initial filtration, it will enter the bottom cylinder 11. At this time, the water pump 14 can be used to pump it out with the help of the water pumping pipe 13 and send it to the sedimentation tank 20 through the water delivery pipe 15.

[0026] Two sludge pumps 17 are installed on one side of the top of the base 12, and each of the sludge pumps 17 has a discharge pipe 18 installed at its output end and a suction pipe 16 installed at its input end, with one end of the suction pipe 16 extending into the interior of the sedimentation tank 20.

[0027] A drive motor 22 is installed at the top center of the sedimentation tank 20, and the output end of the drive motor 22 extends into the interior of the sedimentation tank 20 and is equipped with an agitator 19.

[0028] Two feeding hoppers 21 are installed on one side of the top of the sedimentation tank 20, and the bottom of the feeding hoppers 21 extends into the interior of the sedimentation tank 20.

[0029] Specifically, such as Figure 1 and Figure 3 As shown, when wastewater enters the sedimentation tank 20 and accumulates to a certain amount, chemicals can be added from the chemical feeding hopper 21, and the stirring paddle 19 is driven by the drive motor 22 to stir it, so that the chemicals and wastewater are fully mixed and reacted. After the reaction is completed, the wastewater and sediment are allowed to settle. Subsequently, the wastewater and sediment are extracted by the sludge pump 17 and subjected to ordinary filtration treatment.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
