Description

Technical Field

[0001] The utility model relates to the technical field of wastewater detection, in particular to a filtering device for industrial wastewater detection. Background Art

[0002] The filtration step in industrial wastewater testing is an important part of ensuring the accuracy of wastewater sample processing.

[0003] When testing filtration, you first need to select a suitable filter membrane according to the test requirements, then install the filter membrane on the filter, and keep the filter membrane flat and wrinkle-free, and fit tightly with the filter. Then slowly pour the wastewater sample into the filter and filter it through the filter membrane. During the filtration process, you should pay attention to controlling the flow rate and pressure to avoid rupture or clogging of the filter membrane. After the filtration is completed, wash the filter membrane several times with distilled water or other suitable washing liquid to remove residues attached to the filter membrane. Finally, place the washed filter membrane in an oven and dry it to constant weight. Then remove the filter membrane, cool it to room temperature in a dryer, and weigh it. By comparing the weight difference of the filter membrane before and after filtration, parameters such as the suspended solids content in the wastewater can be calculated.

[0004] However, the existing filter device still has the following problems when used:

[0005] 1. The filter disassembly steps are complicated and the filter membrane installation is inconvenient;

[0006] 2. The wastewater sample cannot pass through the filter membrane evenly. When the wastewater sample enters the filter, it tends to flow to a point on the filter membrane installed on the filter, and then slowly disperses. In addition, the impact force of the water flow may cause wrinkles on the filter membrane, which affects the accuracy of the test to a certain extent.

[0007] Therefore, a filtering device for detecting industrial wastewater is proposed. Utility Model Content

[0008] In view of this, the embodiments of the present invention hope to provide a filtering device for industrial wastewater detection to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0009] The technical solution of the embodiment of the utility model is achieved as follows: a filtering device for detecting industrial wastewater, comprising a housing:

[0010] A through slot is provided on the outer side of the shell, and a filter mechanism is inserted into the through slot;

[0011] The filtering mechanism includes a plug-in plate, a filter and an annular pressing plate;

[0012] The outer side of the filter is fixed to the inner side of the plug-in board, and the upper surface of the filter is provided with an annular pressing plate;

[0013] The top of the shell is rotatably connected to a water inlet pipe via a bearing, and a driving mechanism for driving the water inlet pipe to rotate is provided on the top of the shell;

[0014] The bottom of the water inlet pipe is connected with a blind pipe, one side of the blind pipe is connected with a guide plate, and the bottom of the guide plate is evenly provided with through holes.

[0015] In some embodiments, a bracket is fixed to the outside of the shell.

[0016] In some embodiments: a through slot protrudes from one side of the plug board.

[0017] In some embodiments: the driving mechanism includes a motor, a reduction gear, a driving gear and a driven gear;

[0018] The passive gear is meshed with the driving gear, the output shaft of the reduction gear box is fixed on the inner side of the driving gear, and the output shaft of the motor is fixedly connected to the input shaft of the reduction gear box.

[0019] In some embodiments: the inner side of the passive gear is sleeved on the outer side of the water inlet pipe.

[0020] In some embodiments, the output shaft of the reduction gearbox is rotatably connected to the housing via a bearing.

[0021] In some embodiments, the bottom of the shell is connected to a drain pipe, and a valve is installed on the outside of the drain pipe.

[0022] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:

[0023] 1. The utility model removes the annular pressure plate placed on the filter, lays the filter membrane flat on the filter, then presses the annular pressure plate on the filter membrane, and then installs the filter inside the housing through the through groove. At this time, the outer side of the filter is against the inner wall of the housing, and the installation of the filter is completed with the plug-in plate. The operation is simple and the filter is easy to install.

[0024] 2. The utility model drives the water inlet pipe to rotate slowly through the driving mechanism. The wastewater sample passes through the water inlet pipe, blind pipe and drainage plate and falls evenly on the filter membrane installed on the filter through the through hole, so as to prevent the wastewater sample from flowing to a point on the filter membrane of the filter and avoid wrinkles on the filter membrane, thereby laying a good foundation for detection accuracy.

[0037] like Figure 1 As shown in FIG-5 , the embodiment of the present utility model provides a filtering device for detecting industrial wastewater, including a housing 2:

[0038] A through slot 21 is formed on the outer side of the housing 2, and a filter mechanism 5 is inserted into the through slot 21;

[0039] The filter mechanism 5 includes a plug-in plate 51, a filter 52 and an annular pressure plate 53;

[0040] The outer side of the filter 52 is fixed to the inner side of the plug board 51, and the upper surface of the filter 52 is provided with an annular pressing plate 53;

[0041] The top of the housing 2 is rotatably connected to a water inlet pipe 3 via a bearing, and a driving mechanism 4 is provided on the top of the housing 2 for driving the water inlet pipe 3 to rotate;

[0042] The bottom of the water inlet pipe 3 is connected to a blind pipe 31 , one side of the blind pipe 31 is connected to a guide plate 32 , and through holes 33 are evenly formed at the bottom of the guide plate 32 .

[0043] In this embodiment, specifically: a bracket 1 is fixed to the outer side of the shell 2 , and the bracket 1 is used to stabilize the shell 2 .

[0044] In this embodiment, specifically, a through slot 21 is protruded from one side of the plug-in board 51 to facilitate the inspection personnel to extract and install the filter 52 .

[0045] In this embodiment, specifically: the driving mechanism 4 includes a motor 41, a reduction gear 42, a driving gear 43 and a driven gear 44;

When the wastewater sample is injected into the housing 2, the motor 41 is started, and the output shaft of the motor 41 drives the active gear 43 to rotate slowly through the reduction gear 42, transmitting the passive gear 44, and the passive gear 44 drives the water inlet pipe 3 to rotate slowly. At the same time, the wastewater sample, under the drainage of the water inlet pipe 3, the blind pipe 31 and the guide plate 32, falls evenly on the filter membrane installed on the filter 52 through the through hole 33, avoiding the wastewater sample from flowing to a point on the filter membrane on the filter, and also avoiding wrinkles in the filter membrane, laying a good foundation for detection accuracy.

At this time, the outer side of the filter 52 abuts against the inner side wall of the housing 2, and the installation of the filter 52 is completed with the plug-in plate 51. The operation is simple and the filter 52 is easy to install.

[0049] Subsequently, when the wastewater sample is injected into the housing 2, the motor 41 is started, and the output shaft of the motor 41 drives the driving gear 43 to rotate slowly through the reduction gear 42, and transmits the driven gear 44, and the driven gear 44 drives the water inlet pipe 3 to rotate slowly. At the same time, the wastewater sample passes through the water inlet pipe 3, the blind pipe 31 and the guide plate 32, and falls evenly on the filter membrane installed on the filter 52 through the through hole 33, thereby preventing the wastewater sample from flowing to a point on the filter membrane on the filter, and also preventing the filter membrane from wrinkling, which lays a good foundation for detection accuracy.
