Description

TECHNICAL FIELD

[0001] The utility model relates to sewage sampling technical field, concretely is a sewage automatic sampler. BACKGROUND

[0002] When sewage treatment research, need to sample sewage, through to sample detection, analysis to determine the degree of water pollution, pollution types and related water quality parameters.

[0003] In prior art, the sampler used for sewage collection includes a suction head, a water pipe connected to the end of the suction head, and a collection barrel and a water pump connected to the other end of the water pipe. When in use, the suction head is inserted into the sewage, and the sewage is sucked into the collection barrel through the water pipe to complete the collection of the sewage.

[0004] However, the use of the suction head directly to collect the sewage cannot prevent weeds from entering the barrel, resulting in the sewage sample containing weeds. Some suction heads are provided with a filter screen to prevent weeds from entering, but larger impurities can block the filter screen. When the filter screen is blocked by larger impurities, the speed of the sewage passing through the filter screen will decrease significantly. For example, in some sewage sampling containing a large amount of silt and fiber impurities, these impurities can easily accumulate on the filter screen in a short time, so that the suction force of the suction head cannot effectively suck the sewage into the water pipe. Originally, the collection of a certain amount of sewage can be completed in a few minutes. After the filter screen is blocked, the water pump will be idle, the possibility of damage to the water pump will be increased, and it is not easy to clean. To solve the above problems, we propose a sewage automatic sampler. UTILITY MODEL CONTENTS

Detailed Implementation

[0023] 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.

[0024] Example: Figures 1-5 As shown, this utility model provides an automatic wastewater sampler, including an assembly pipe 1. One end of the assembly pipe 1 is fixedly connected to an inlet pipe 101. A filter assembly 2 is installed inside the assembly pipe 1. A control assembly 3 is installed on the side of the filter assembly 2 near the inlet pipe 101. The filter assembly 2 includes a mounting frame 201. A guide window 202 is opened at the top of the assembly pipe 1. The mounting frame 201 is slidably connected to the inner wall of the guide window 202. Rotating rollers 204 are rotatably connected to both sides of the inner wall of the mounting frame 201. The rotating rollers 204 are symmetrically distributed along the axis of the mounting frame 201. A filter plate 203 is fixedly connected to one side near the center of the mounting frame 201. The two filter plates 203 completely enclose the mounting frame 201. The surface of the filter plate 203 has multiple evenly distributed filter holes 205. A handle is fixedly connected to the top of the mounting frame 201. The two filter plates 203 can be closed or separated to cooperate with the control component 3 for filtration. The mounting frame 201 is slidably connected to the guide window 202, and the filter plates 203 can be separated. The mounting frame 201 can be easily removed for cleaning through the handle, which is convenient for maintenance and upkeep of the equipment and ensures the long-term stable operation of the equipment.

[0025] Furthermore, the control component 3 includes multiple mounting seats 301, which are placed inside the assembly tube 1. The mounting seats 301 are positioned on the side of the filter plate 203 near the inlet pipe 101. The multiple mounting seats 301 are fixedly connected to both sides of the inner wall of the assembly tube 1. The mounting seats 301 on both sides are symmetrically distributed along the axis of the assembly tube 1. A fixing window 302 is provided on the side of the mounting seat 301 near the center of the assembly tube 1. Mounting grooves 303 are provided on both sides of the inner wall of the fixing window 302. The mounting grooves 303 on both sides are symmetrically distributed along the axis of the mounting seat 301. A moving roller 304 is housed within the mounting groove 303. Both ends of the moving roller 304 are rotatably connected to the bottom of the inner cavity of the mounting groove 303. Torsion springs 305 are sleeved on both ends of the moving roller 304. The torsion springs 305 are placed inside the mounting groove 303. One end of the torsion spring 305 is fixedly connected to the inner wall of the mounting groove 303, and the other end is fixedly connected to the inner wall of the mounting groove 303. The surface of the motion roller 304 is fixedly connected, and a connecting seat 306 is sleeved in the middle of the motion roller 304. One end of the connecting seat 306 is fixedly connected to the motion roller 304, and the other end of the connecting seat 306 extends to the filter plate 203. A positioning window 307 is opened at the end of the connecting seat 306 near the filter plate 203. A guide wheel 308 is installed in the positioning window 307. The side of the guide wheel 308 near the mounting frame 201 contacts the filter plate 203. During normal use, the guide wheel 308 contacts the filter plate 203 under the action of the torsion spring 305, so that the two filter plates 203 completely close the mounting frame 201 for filtration. When larger impurities and weeds enter, they form a blockage, and the filter plate 203 is subjected to greater force. The two filter plates 203 unfold to overcome the elastic force, preventing the water pump from running dry and being damaged. After the sewage enters the assembly pipe 1 from the inlet pipe 101, it first contacts the control component 3. Under normal circumstances, the guide wheel 308 in control component 3 is pressed tightly against the filter plate 203 by the torsion spring 305, causing the two filter plates 203 to close tightly and completely seal the mounting frame 201. At this time, sewage flows through the filter plate 203. Since the filter holes 205 on the surface of the filter plate 203 can block weeds and large particles, only the sewage that has undergone preliminary filtration can continue to flow in the assembly pipe 1. When larger weeds or large particles enter, they will exert greater pressure on the filter plate 203. If the pressure exceeds the elastic force of the torsion spring 305, the two filter plates 203 will unfold, and some sewage will still enter, thus preventing the assembly pipe 1 from being completely blocked and damaging the subsequent equipment.

[0026] Working principle: when using the device, sewage from the inlet pipe 101 into the assembly pipe 1, first contact to control assembly 3. Under normal circumstances, the guide wheel 308 in the control assembly 3 under the action of torsional spring 305 tightly against the filter plate 203, so that two filter plate 203 tightly closed, the installation frame 201 is completely closed. At this time, the sewage flow through the filter plate 203, because the filter plate 203 surface filter hole 205 can block the weeds and large particles of impurities, only after the preliminary filtration of sewage can continue to flow in the assembly pipe 1, when there are larger weeds or large particles of impurities into, will produce a greater pressure on the filter plate 203. If the pressure exceeds the torsional spring 305 elastic force, two filter plate 203 will be opened, let these larger impurities through smoothly, thereby avoiding the assembly pipe 1 and damage to subsequent purification equipment, special for weeds and large particles of impurities are filtered, can effectively prevent these impurities into the subsequent purification treatment link, improve the efficiency and quality of sewage purification, when the larger impurities block, filter plate 203 can be automatically opened, adapt to different sewage situation, reduce the need for manual intervention, installation frame 201 and guide window 202 sliding connection, and filter plate 203 can be separated, by handle can easily remove the installation frame 201 cleaning, convenient maintenance and maintenance equipment, ensure the long-term stable operation of the equipment.
