Technical Field

[0001] The invention relates to the technical field of sewage flow measurement, and in particular to a weighing type sewage flow measurement device. Background Art

[0002] The emission of flue gas, waste liquid, sewage, etc. has caused serious pollution to the atmosphere and water resources, and seriously threatened the living environment of human beings. In order to achieve sustainable development, it is necessary to manage air and water resources, and sewage flow measurement is the foundation of water pollution control. Flowmeter is defined as an instrument that indicates the measured flow rate and (or) the total amount of fluid in a selected time interval. There are many types of flowmeters, which are divided into differential pressure flowmeters, rotor flowmeters, throttling flowmeters, slit flowmeters, ultrasonic flowmeters, etc., but some flowmeters can only be used for open channel fluids, full pipe flows or pure liquid fluids. There is no feasible method for measuring fluids containing solid impurities and non-full pipe flows.

[0003] The current sewage flow measurement device is affected by various external factors and has the disadvantages of instability, large errors, and short service life. It is also inconvenient to adjust the sewage flow during use. How to study a sewage flow measurement device is an urgent problem that needs to be solved. Summary of the invention

Implementation

[0012] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiment is one of the embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of the present invention.

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0014] Example: Figure 1 to Figure 2As shown, the present invention is a weighing type sewage flow measurement device, which includes a crushing mechanism 3, the left side of the crushing mechanism 3 is connected to the water inlet pipe 1, the right side is connected to the drain pipe 12, a motor 2 is installed on the top, and a rotating shaft 11 and a crushing blade 10 are installed inside the crushing mechanism 3. The crushing mechanism 3 is connected to the flip container 7 through the drain pipe 12, a timer 6 is installed on the flip container 7, the flip container 7 is installed on the eccentric bracket 4 through the bearing 5, an iron block 13 is placed at the bottom of the flip container 7, a drain pipe 12 is provided on the right side, and the flip container 7 is connected to the weighing container 8 through the drain pipe 12. A weighing device 14 is provided on the weighing container 8, and the weighed sewage is discharged through the outlet pipe 9.

[0015] A motor 2 is installed on the top of the crushing mechanism 3, and the motor 2 is connected to the rotating shaft 11 to drive the rotating shaft 11 to rotate. A sharp crushing blade 10 is arranged on the rotating shaft 11, which can be convenient for crushing large impurities in the sewage.

[0016] A timer 6 is installed on the flip container 7. The sewage after the impurities are crushed by the crushing mechanism 3 enters the flip container 7, and the timing starts. When the flip container 7 flips the sewage into the weighing container 8 through the drain pipe 12, the timing stops.

[0017] The bearing 5 of the eccentric bracket 4 is arranged on the upper side of the center of gravity of the inverting container 7 containing the iron block 13, and is located on the side where the iron block 13 is installed. When there is no water in the inverting container 7, since the iron block 13 is located on the left side, the mass of the left side of the eccentric bracket 4 is greater than that of the right side, causing the inverting container 7 to deviate to the left side. After a certain amount of water is added, the weight of the left and right sides of the eccentric bracket 4 is equal, so that the overall center of gravity of the inverting container 7 and the eccentric bracket 4 are both on the same vertical plane. Water should be continuously added to a certain extent, and the center of gravity of the inverting container 7 containing the iron block will continuously shift to the right, until the inverting container 7 is inverted when the center of gravity position is exactly at the same height as the eccentric bracket 4.

[0018] The weighing container 8 is provided with a weighing device 14, which measures the weight of the sewage entering the weighing container 8 within the timing time, thereby converting the sewage flow rate according to the weight during the timing time.

[0019] The drainage pipe 12 is made of 304 stainless steel vacuum bellows.

[0020] When the present invention is used, after the sewage enters the crushing mechanism 3 through the water inlet pipe 1, the motor 2 drives the rotating shaft 11 to rotate. The rotating shaft 11 is provided with a sharp crushing blade 10, which can crush larger impurities in the sewage. When there is no water in the flip container 7, since the iron block 13 is located on the left, the mass of the left side of the eccentric bracket 4 is greater than the right side, causing the flip container 7 to deviate to the left. The sewage after the impurities are crushed by the crushing mechanism 3 enters the flip container 7 through the drain pipe 12, and the timer 6 starts timing. After a certain amount of sewage enters, the weight of the left and right sides of the eccentric bracket 4 is equal, so that the overall center of gravity of the flip container 7 and the eccentric bracket 4 are both on the same vertical plane. As the sewage continues to enter to a certain extent, the center of gravity of the flip container 7 containing the iron block 13 continues to shift to the right until the flip container 7 is flipped when the center of gravity position is exactly at the same height as the eccentric bracket 4. When the flip container 7 flips the sewage through the drain pipe 12 into the weighing container 8, the timing stops. Then the weighing device 14 measures the weight of the sewage entering the weighing container 8 within the timing time, thereby converting the sewage water flow rate according to the weight of the timing time.

[0021] The specific calculation steps are as follows: the timing time is t seconds. Within the timing time of t seconds, the mass of the sewage is n tons. According to the conversion relationship between sewage mass and volume, the sewage volume is n cubic meters. Therefore, the sewage flow rate measured by the device is n / t cubic meters per second.

[0022] Finally, it should be noted that the above-described embodiments are only specific implementations of the present invention, which are used to illustrate the technical solution of the present invention rather than to limit it. The protection scope of the present invention is not limited thereto, although the present invention has been described in detail with reference to the above-mentioned embodiments.

[0023] Those skilled in the art should understand that any person skilled in the art can modify, change or replace the technical solutions described in the above embodiments within the technical scope disclosed by the present invention, without making the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and all of them should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
