Description

Technical Field

[0001] The invention relates to the technical field of sludge settling ratio detection, in particular to a sludge settling ratio detection device. Background Art

[0002] For sewage treatment plants, the sludge in the biochemical pool is as important as the engine of a car. Keeping the sludge in a good performance state is an important task in production management, and the sludge settling ratio (SV30) is an important indicator for monitoring the sludge performance state. The SV30 value can reflect the settling speed of sludge flocs and the quality of the settling effect.

[0003] The sludge settling ratio (SV) test method involves the inspector going to the water treatment tank in person to extract samples and bringing these samples back to the laboratory for testing. In addition, due to the time difference from sampling to testing and changes in the sample state, the test results may be inaccurate. In order to achieve direct SV value determination on site, the water treatment tank site is usually equipped with a sludge settling ratio detection device.

[0004] However, most of these existing detection devices use sampling mechanisms such as centrifugal pumps, rotor pumps or gear pumps when sampling. These mechanisms may have adverse effects on the state of the sample during the sampling process and cannot simulate the effect of manually using a measuring cylinder to accurately scoop the sample, so the test results often have large deviations.

[0005] In addition, after repeated use, the measuring cylinder inside the testing mechanism of these testing devices will have residual microorganisms. These microorganisms can easily breed and multiply in the measuring cylinder, thereby interfering with the normal measurement function of the measuring cylinder. This not only affects the accuracy of the test, but may also pose a threat to the long-term stable operation of the equipment. Summary of the invention

[0006] The object of the present invention is to provide a sludge settling ratio detection device. When measuring the SV value, the measuring cylinder can be placed into a water treatment tank under the action of a driving mechanism, and the measuring liquid can be placed into the measuring cylinder under the action of an opening and closing mechanism, a liquid control mechanism and a passive mechanism. Then, the measuring cylinder is closed and the measuring head body is within the working range during the continuous operation of the driving mechanism, thereby reducing the time difference from sampling to testing.

[0007] In addition, after the measurement is completed and the driving mechanism continues to work, the measuring liquid in the measuring cylinder can be discharged, and driven by the flipping mechanism, the spraying mechanism is within the working range of the measuring cylinder and the measuring head body. Under the action of the energy storage mechanism, the energy release mechanism and the water supply mechanism, the spraying mechanism cooperates with the lifting mechanism to rinse the measuring cylinder and the measuring head body, thereby facilitating the next SV value measurement.

In this embodiment, by the arrangement of the fourth connecting block 181, the slide rod 182, the third spring 183, the pressure supply head 184, the pushing head 185 and the pressing sheet 187, a pressure supply head 184 is provided on one side. When the movable tooth plate 94 moves, the fourth connecting block 181 fixed on the surface of the driving tooth plate 94 can drive the sliding rod 182, the third spring 183 and the pressure supply head 184 to move, so that the pressure supply head 184 squeezes the lower pressure rod 186, and under the action of the lower pressure rod 186, the pressure plate 187 works on the energy release mechanism 19. In addition, after the pressure supply head 184 reaches a certain position, the pressure supply head 184 can fit with the pushing head 185, and then under the action of the pushing head 185, the pressure supply head 184 moves, thereby releasing the positive squeezing of the pressure supply head 184 on the lower pressure rod 186, and under the action of the third spring 183, the pressure supply head 184 changes to lateral squeezing of the lower pressure rod 186. After the fourth connecting block 181 drives the pressure supply head 184 to reset, the pressure supply head 184 can be reset laterally under the action of the third spring 183.

[0059] The energy release mechanism 19 includes a limiting tube 191 sliding on the surface of the pressing plate 187. The inner cavity of the limiting tube 191 contains an energy storage airbag 192. The other end of the energy storage airbag 192 is connected to a second connecting air pipe 193. Both sides of the surface of the second connecting air pipe 193 are connected to a one-way valve 194. In this embodiment, through the setting of the limiting tube 191, the energy storage airbag 192, the second connecting air pipe 193 and the one-way valve 194, when the pressing plate 187 squeezes the energy storage airbag 192, the gas is discharged from the one-way valve 194 on one side. After the energy storage airbag 192 is not squeezed, it can be absorbed through the second connecting air pipe 193 and the one-way valve 194 on the other side, thereby enabling the water supply mechanism 20 to work.

[0060] The water supply mechanism 20 includes a windmill driving block 201 rotating in the inner cavity of the second connecting air pipe 193, a fifth rotating rod 202 is fixed to the surface of the windmill driving block 201, one end of the fifth rotating rod 202 is fixed to a peristaltic wheel 203, a peristaltic tube 204 is meshed on the surface of the peristaltic wheel 203, the other end of the peristaltic tube 204 is fixed to the surface of the housing 1, the peristaltic tube 204 and the connecting water pipe 161 are connected through a hose, and the other end of the peristaltic tube 204 is connected to the external water pipe. In this embodiment, the peristaltic tube 204 is connected to the external water pipe. Through the arrangement of the windmill driving block 201, the fifth rotating rod 202, the peristaltic wheel 203 and the peristaltic tube 204, when the second connecting air pipe 193 absorbs gas, the windmill driving block 201 can be rotated under the impact of the gas, so that under the action of the windmill driving block 201, the fifth rotating rod 202 drives the peristaltic wheel 203 to rotate, and the peristaltic tube 204 attached to the surface of the peristaltic wheel 203 can deliver water, so that water enters the connecting water pipe 161.

[0061] The auxiliary mechanism 21 includes a fixed block 211 fixed to the surface of the limiting block 157, a fourth spring 212 is fixed to the surface of the fixed block 211, and the other end of the fourth spring 212 is fixed to the surface of the engaging tube 154, which assists the rotation of the limiting block 157 and improves the stability of the limiting block 157 during rotation.

[0062] Working principle: When in use, the device can be installed in the working area of ​​the biochemical pool, and the measuring cylinder 4 is placed above the pool liquid. When the sludge settling ratio of the biochemical pool needs to be measured, the staff can use the driving mechanism 9. Under the action of the motor 91, the output shaft 92 rotates, and the driving gear 93 fixed to the surface of the output shaft 92 can drive the tooth plates 94 on both sides to move, and then under the action of the tooth plates 94 on both sides, the lower driving block 3 and the upper driving block 6 move upward and downward respectively.

[0063] When the toothed plate 94 on one side drives the lower driving block 3 to move downward, the measuring cylinder 4 can be immersed in water, and under the action of the moving distance, the 1000ml scale line in the measuring cylinder 4 can be flush with the water surface, which is recorded as VS. At this time, the lower pressure supply body 107 and the lower force-bearing head 101 come into contact, and then under the action of the force-bearing head 101, the first connecting rod 102 drives the first piston head 103 to move, and under the action of the first piston head 103, the first connecting air pipe 105 drives the second piston tube 121 to work, and under the action of the second piston tube 121 , so that the second connecting rod 123 moves in the inner cavity of the worm 124, and then under the action of the thread, the worm 124 and the worm wheel 125 are meshed, and under the action of the worm wheel 125, the second rotating rod 126 drives the first rotating rod 111 to rotate, and then under the action of the first rotating rod 111, the first connecting block 112 drives the sealing cover 113 to rotate, so that the bottom of the measuring cylinder 4 and the pool liquid are connected, so that the mixed liquid enters the measuring cylinder 4, and because the 1000ml scale line is flush with the water surface at this time, the measuring cylinder 4 has a suitable amount of water.

[0064] After the mixed liquid is in the measuring cylinder 4, the staff can reverse the motor 91, and then under the action of the motor 91, the lower driving block 3 and the measuring cylinder 4 move upward. It is worth noting that since the fit between the force head 101 and the first piston tube 104 is released, the sealing cover 113 re-seals the measuring cylinder 4, so that the mixed liquid is in the inner cavity of the measuring cylinder 4. In the process of the measuring cylinder 4 moving upward, the upper driving block 6 drives the electric push rod 7 and the measuring head body 8 to move downward at the same time, and the measuring head body 8 enters the inner cavity of the measuring cylinder 4. The measuring head body 8 uses light scattering method to measure suspended particles in water. When light passes through particles in the water, the light will be scattered. The intensity of the scattered light is proportional to the turbidity in the water within a certain concentration range. The turbidity value at the sensor can be measured. The electric push rod 7 drives the measuring head body 8 to move up and down. The sludge interface height in the measuring cylinder 4 can be measured through electrodes and lasers. The measurement time is calculated by the control mechanism body 5. After the test is completed, the electric push rod 7 drives the measuring head body 8 to rise, and the turbidity value of the supernatant can be measured.

[0065] The working principle of the measuring head body 8 is to measure the current intensity of the laser sensor and adopt a multi-point averaging algorithm, for example, to accurately measure the turbidity value and the sludge cross-sectional height value, recorded as V1, so as to calculate the volume value of the sludge sedimentation; then, the timer is used to accurately time 30 minutes, and under the action of the control mechanism body (5), SV30 (%) = V1 / Vs * 100% is used to calculate the SV30 value and the value of the supernatant. Under the action of the control mechanism body 5, the sludge sedimentation rate is displayed, and abnormal sedimentation states such as sludge floating and sludge swelling are intelligently identified.

[0066] After the measurement is completed, if the measured value exceeds the specified range, under the action of the control mechanism body 5, an alarm is given to the outside world, and the staff can use the driving mechanism 9 again. Under the action of the driving mechanism 9, the lower driving block 3 drives the measuring cylinder 4 to move upward, and the upper driving block 6 drives the measuring head body 8 to move downward, and during the movement, the second connecting block 151 drives the insertion tube 152 and the driving ball 153 to slide downward in the inner cavity of the meshing tube 154. Under the action of the driving ball 153 and the meshing tube 154, the meshing tube 154 drives the flipping block 155 and the third connecting block 156 to flip, and then the lower spray head 165 and the upper spray head 163 are rotated into the working area, so that the lower spray head 165 is aligned with the inner cavity of the measuring cylinder 4, and the upper spray head 163 is on the lower side of the measuring head body 8.

[0067] At this time, under the action of the designated force-bearing head 101 and the pressure-supplying body 107 , the sealing cover 113 is opened again, so that the measuring liquid in the inner cavity of the measuring cylinder 4 is discharged, thereby achieving the purpose of emptying the measuring cylinder 4 .

[0068] At this time, the pressure supply head 184 continuously presses the pressing rod 186, so that the inner cavity of the energy storage airbag 192 is compressed, and the gas of the energy storage airbag 192 is discharged from the side of the second connecting air pipe 193. When the fourth connecting block 181 descends to a certain position, the pressure supply head 184 and the push head 185 fit together, and then under the action of the push head 185, the pressure supply head 184 moves laterally, thereby releasing the release between the pressure supply head 184 and the pressing rod 186, and the energy storage airbag 192 is released. After 92 is free from the restriction of the pressing plate 187, the energy storage airbag 192 inhales air from the outside and gradually restores its shape under the action of its own elastic force. When the energy storage airbag 192 inhales air, the gas in the inner cavity of the second connecting air pipe 193 can blow the windmill driving block 201 to rotate, thereby making the peristaltic wheel 203 and the peristaltic tube 204 work. Under the action of the peristaltic tube 204, liquid is supplied to the spray mechanism 16, thereby assisting the spray mechanism 16 to flush the measuring head body 8 and the measuring cylinder 4.

[0069] When the spray mechanism 16 is working, the special-shaped windmill block 171 arranged in the inner cavity of the connecting water pipe 161 can rotate under the impulse of the water flow, and then under the action of the third rotating rod 172, the fourth rotating rod 173, the turntable 174, the first hinged rod 175 and the second hinged rod 176, the lower spray head 165 drives the lower connecting hose 164 to rise and fall, thereby increasing the flushing range of the spray mechanism 16 on the measuring cylinder 4 and improving the practicality of the device.

[0070] After the energy stored in the energy storage airbag 192 is released, the work of the spray mechanism 16 is completed, and then the staff uses the driving mechanism 9 again. Under the action of the driving mechanism 9, the measuring cylinder 4 and the measuring head body 8 are reset. During the resetting of the measuring head body 8, the pressure supply head 184 slides against the lower pressure rod 186. When the pressure supply head 184 is separated from the surface of the lower pressure rod 186, the pressure supply head 184 can be reset under the action of the third spring 183, making it convenient for the next work.
