Figure 1-Figure 3 In this embodiment, a filterable wastewater sampling device is provided, and its main body includes a sampling component 100, a filtering component 200 and a cleaning component 300.

[0029] The sampling assembly 100 includes a temporary storage barrel 110, a sampling tube 120 arranged in the middle of the lower end of the temporary storage barrel 110 and connected to the interior of the temporary storage barrel 110, and a piston rod 130 arranged inside the temporary storage barrel 110. Liquid outlets 111 are arranged on the upper and lower sides of the middle of one side wall of the temporary storage barrel 110, and a sealing cover 112 is threadedly arranged on the liquid outlet 111. A guide plate 121 is arranged inside the sampling tube 120, and a rubber plug 122 is arranged at the lower end of the sampling tube 120. A traction rope 123 is fixed to the side wall of the rubber plug 122, and the other end of the traction rope 123 is fixed to the outer wall of the temporary storage barrel 110. A handle 131 is vertically fixed to the upper end of the piston rod 130. Preferably, in the present embodiment, the outer wall of the sealing cover 112 is provided with an anti-slip portion 113, and the anti-slip portion 113 provided on the outer wall of the sealing cover 112 increases the friction between the operator's hand and the sealing cover 112, thereby preventing the operator from slipping when screwing the sealing cover 112. A scale line 114 is provided in the middle of the front end of the temporary storage barrel 110, and the scale line 114 provided on the temporary storage barrel 110 facilitates the operator to know the amount of wastewater extracted from the temporary storage barrel 110.

[0030] The filter assembly 200 includes a filter tube 210 obliquely disposed on the side wall of the sampling tube 120 and connected to the interior of the sampling tube 120 , and a filter cartridge 220 disposed inside the filter tube 210 . A threaded cap 211 is threadedly mounted on the end of the filter tube 210 .

[0032] Combination Figure 1-Figure 3 The filterable wastewater detection sampling device of the present embodiment is specifically used as follows: the operator opens the rubber stopper 122, extends the sampling tube 120 below the water level, and pulls the piston rod 130 upward through the handle 131, so that negative pressure is formed inside the temporary storage cylinder 110 to draw the wastewater into the temporary storage cylinder 110. When the wastewater enters the temporary storage cylinder 110, the guide plate 121 located in the sampling tube 120 guides the wastewater and guides the wastewater into the filter cartridge 220 of the filter tube 210. The filter cartridge 220 removes floating objects in the wastewater. The large particles of impurities are filtered and processed, and the filtered wastewater finally enters the temporary storage cylinder 110. When the filter cartridge 220 needs to be cleaned later, the operator manually controls the cleaning plate 320 to slide on the inner wall of the filter cartridge 220 in the filter tube 210 through the pull rod 310. When the cleaning plate 320 slides on the inner wall of the filter cartridge 220, the floating objects and large particles of impurities filtered on the filter cartridge 220 are scraped off, thereby cleaning the filter cartridge 220. Compared with the existing cleaning method, the utility model has the advantage of being easy to clean the filter cartridge 220.
