Description

Technical Field

[0001] This utility model belongs to the field of environmental monitoring technology and relates to a sludge sampler. Background Technology

[0002] Anaerobic reactors such as UASB and IC remove organic matter from wastewater through the growth and reproduction of anaerobic granular sludge within the reactor. During the operation of UASB and IC anaerobic reactors, the growth of the granular sludge within the reactor, such as the characteristics of the sludge at different depths and the thickness of the sludge bed, directly affects the process's performance.

[0003] The sampling ports of existing anaerobic reactors are all set to fixed-depth sampling. This sampling method can only meet the operational monitoring needs when the reactor is running stably. In actual operation, there are situations where changes in the influent pollutant load or fluctuations in other factors cause abnormal operation of the reactor (such as sludge reduction or sludge disintegration), making it impossible to dynamically monitor the sludge bed in the reactor using fixed-depth sampling.

[0004] Therefore, it is necessary to provide a sampler that can obtain sludge samples at different depths. Utility Model Content

[0005] To at least address the problem in the prior art that fixed-depth sampling in anaerobic reactors cannot achieve sludge sampling at different depths, this utility model provides the following technical solution: a sludge sampler, suitable for anaerobic reactors, the sludge sampler comprising:

[0006] A sampling tube, the inlet end of which extends into the sludge bed inside the anaerobic reactor, and the outlet end of which is located outside the anaerobic reactor and is equipped with a sampling valve for sludge sampling.

[0011] The rigid tube is located outside the anaerobic reactor. The inlet end of the rigid tube passes through the side wall of the anaerobic reactor and is connected to the outlet end of the flexible tube. The outlet end of the rigid tube is equipped with the sampling valve.

[0012] Optionally, in the above-mentioned sludge sampler, the height adjustment device includes: an electric motor and a driving wheel and a driven wheel installed on the inner wall of the anaerobic reactor;

[0013] The electric motor is located outside the anaerobic reactor, and is connected to the anaerobic reactor via a flange. The control terminal of the electric motor is connected to the control panel.

[0014] In the vertical direction, the driving wheel and the driven wheel are spaced apart. The driving wheel is connected to the output end of the motor, and the driving wheel and the driven wheel are connected by a transmission.

[0015] Optionally, in the above-mentioned sludge sampler, a connecting rod and a fixing anchor are provided on the inner wall of the anaerobic reactor;

[0027] The beneficial effects of the technical solution provided by this utility model embodiment are:

[0028] This application utilizes a sampling tube for sludge sampling. A height adjustment device regulates the height of the sampling tube's inlet (sampling port), and a display panel shows the height of the inlet. During use, the sampling tube moves up and down with the height adjustment device. The device's built-in algorithm calculates the movement height, determining the current height of the sampling port, which is then displayed on the control panel (or the depth of the sampling point).

They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected," "linked," and "set up" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a direct connection or an indirect connection through intermediate components; a wired connection, a radio connection, or a wireless communication signal connection. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0034] Please see Figure 1-2This utility model provides the following technical solution: a sludge sampler, suitable for anaerobic reactors (including anaerobic reaction tanks or anaerobic towers), comprising: a sampling tube, a height adjustment device, and a control panel 2. Specifically, the inlet end (also called the sampling port 11) of the sampling tube extends into the sludge bed (not shown in the figure) inside the anaerobic reactor 7, that is, the inlet end of the sampling tube is connected to the sludge bed, and the outlet end of the sampling tube is located outside the anaerobic reactor 7, and this end is equipped with a sampling valve 9 for sludge sampling. The height adjustment device is installed on the anaerobic reactor 7, and is connected to the wall of the inlet end of the sampling tube. The height adjustment device is used to adjust the height of the inlet end of the sampling tube (referring to the height of the inlet end relative to the bottom inner wall of the anaerobic reactor 7). The control panel 2 is located outside the anaerobic reactor 7, and is connected to the height adjustment device. The control panel 2 is used to set the adjustment height of the height adjustment device and display the height of the inlet end of the sampling tube. In use, the inlet end of the sampling tube is fixed to the height adjustment device using techniques commonly used in the field. The height adjustment device is set via control panel 2, and then activated. The sampling tube moves up and down with the height adjustment device, and the moving height is calculated using the built-in algorithm of the height adjustment device, thus determining the height of the sampling tube inlet 11. The height of the sampling tube inlet 11 (or the depth of the sampling point) is displayed on control panel 2 until the desired height is reached. The height adjustment device then stops operating, and the sampling valve 9 on the sampling tube is opened. The pressure difference between the sludge bed and the inside of the sampling tube causes the sludge to flow out along the sampling tube, thus achieving sludge sample collection. After sampling, the sampling valve 9 is closed. This application meets the sampling needs under different conditions, realizing adjustable depth sampling within the designed depth range, thereby enabling dynamic monitoring of the sludge bed condition within the anaerobic reactor. It should be noted that the sampling depth can be set at the factory via the control panel 2 according to the actual needs of the site (that is, the upper and lower limits of the sampling depth can be set to ensure that the sampling port 11 moves only up and down within the adjustable range). The specific setting parameters are not limited in this embodiment.

[0035] As an embodiment of the specific structure of the sampling tube described above, in this embodiment, the sampling tube is composed of a flexible tube 5 and a rigid tube 4 joined together. Specifically, refer to... Figure 1As shown, the flexible hose 5 is located inside the anaerobic reactor 7. The flexible hose 5 is elastic, and the wall of the inlet end of the flexible hose 5 is fixedly connected to the height adjustment device, so the flexible hose 5 can move up and down with the height adjustment device. In actual operation, the specific connection position between the flexible hose 5 and the height adjustment device can also be selected on the wall of the flexible hose 5 near the inlet end. The rigid tube 4 is located outside the anaerobic reactor 7. The inlet end of the rigid tube 4 passes through the side wall of the anaerobic reactor 7 and is connected to the outlet end of the flexible hose 5. The rigid tube 4 is rigid, which facilitates the insertion of the inlet end of the rigid tube 4 into the anaerobic reactor 7 and fixes it to the reactor. At the same time, the rigid tube 4 can ensure a stable seal between the rigid tube 4 and the anaerobic reactor 7. The outlet end of the rigid tube 4 is equipped with a sampling valve 9. When the required height is reached, the sampling valve 9 is opened to sample the sludge. After sampling, the sampling valve 9 is closed.

[0036] As an embodiment of the specific structure of the aforementioned height adjustment device, in this embodiment, the height adjustment device includes: a motor 1, a driving wheel, and a driven wheel. Specifically, the height adjustment device is installed on the inner wall of the anaerobic reactor 7 using techniques commonly used in the art. For example, a connecting rod 12 and a fixed anchor rod 6 are provided on the inner wall of the anaerobic reactor 7. One end of the fixed anchor rod 6 is fixedly connected to the inner wall of the anaerobic reactor 7, meaning the fixed anchor rod 6 is stationary relative to the side wall of the anaerobic reactor 7. The driven wheel is connected to the other end of the fixed anchor rod 6 via an underwater bearing. The motor 1 is located on the outside of the anaerobic reactor 7 and is fixedly connected to the anaerobic reactor 7 via a flange 3 (or flange 3 connector). Simultaneously, the control end of the motor 1 is connected to the control panel 2. In the vertical direction, the driving wheel and the driven wheel are spaced apart, such as the driving wheel being located below (or above) the driven wheel. The driving wheel is connected to the output end of the motor 1 via the connecting rod 12 located in the center hole of the flange 3. It can be understood that the connecting rod 12 rotates relative to the side wall of the anaerobic reactor 7. The driving wheel and driven wheel are connected by a transmission. Preferably, both the driving wheel and driven wheel are gears, and the two gears are connected by a chain 8, which is connected to the sampling tube; or both the driving wheel and driven wheel are pulleys, and the two pulleys are connected by a belt, which is connected to the sampling tube. Taking the sprocket as an example, in use, the driving gear 13 and driven gear 10 are connected by the chain 8. One end of the sampling tube (referring to the hose 5) is fixed to the chain 8. The motor 1 is turned on. The output end of the motor 1 drives the driving gear 13 to rotate through the connecting rod 12. The driving gear 13 drives the driven gear 10 to rotate through the chain 8. At the same time, the sampling tube moves up and down with the chain 8. By monitoring the number of rotations of the motor 1, the built-in algorithm calculates the corresponding movement height, thereby determining the height of the sampling tube opening 11. The height of the sampling tube opening 11 (which can also be understood as the depth of the sludge bed reached by the sampling tube opening 11) is displayed on the control panel 2 until the required height (referring to the depth of the sampling point) is reached, at which point the motor 1 stops running.

[0037] As a preferred embodiment of the above embodiment, in this embodiment, the connection between the output end of the motor 1 (also called the motor head) and the connecting rod 12 is sealed to the anaerobic reactor 7. If a side-entry stirrer installation method is adopted, simply put, the connecting rod 12 is integrally connected to the output end of the motor 1 and then extends into the anaerobic reactor 7 from the outside of the anaerobic reactor 7 at a certain installation angle. At the same time, the sealing form of the integral shaft is a mechanical seal, which can ensure the long-term stable sealing performance of the connection between the integral shaft and the anaerobic reactor 7.

[0038] Since the interior of anaerobic reactor 7 is an underwater environment, both the driving and driven wheels are made of plastic; the portion of the sampling tube located inside anaerobic reactor 7 (referring to hose 5) is made of steel wire hose 5. The connecting rod 12 and the fixed anchor rod 6 are both made of stainless steel coated with plastic. The driving and driven wheels are connected by transmission components made of plastic.

[0039] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
