Description

Technical Field

[0001] The utility model belongs to the technical field of malodorous gas monitor calibration, and in particular relates to an integrated malodorous gas monitor calibration system. Background Art

[0002] Odor refers to any odorous gas that stimulates the olfactory organ and causes people to feel unpleasant and damages the living environment. Commonly referred to odor pollutants are ammonia, trimethylamine, dimethyl sulfide, methyl mercaptan, dimethyl disulfide, styrene, hydrogen sulfide and carbon disulfide. Odor pollution comes from a wide range of sources, and its emission and diffusion are paroxysmal and instantaneous, which makes odor monitoring instruments used in large quantities. At present, odor monitoring instruments mainly use electronic noses, electrochemical principles and ultraviolet differential principles. If the instrument is not calibrated regularly after long-term use, it will affect the accuracy of the instrument's monitoring data.

[0003] At present, when calibrating an odor gas monitor, it is often necessary to dilute the odor standard gas concentration through a gas diluter. In this process, the staff usually manually replaces the gas cylinders storing the odor gas. The operation steps are cumbersome, which makes the instrument calibration time-consuming. Therefore, further optimization is made for the above problems. Utility Model Content

[0011] The utility model provides an integrated calibration system for odor gas monitors, which has the following beneficial effects:

[0012] 1. The integrated calibration system of the odor gas monitor can drive the odor gas cylinder to rotate intermittently through the coordinated use of the base, the drive component and the exhaust component, so as to replace it, and at the same time, the nitrogen in the nitrogen cylinder and the gas in the odor gas cylinder are discharged into the gas diluter.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. All other embodiments obtained by ordinary technicians in the field without creative work based on the embodiments of the utility model shall fall within the scope of protection of the utility model.

[0025] See also Figures 1 to 9 The utility model provides an integrated calibration system for malodorous gas monitors; it includes a fume hood 1, a gas diluter 2 and a malodorous gas monitor 3 arranged on the top of the fume hood 1, the fume hood 1 includes a base 4 rotatable in a groove on the upper surface of a partition, a driving component arranged near the base 4 for driving the base 4 to rotate, a malodorous gas cylinder 5 arranged on the upper surface of the base 4, a nitrogen cylinder 6 arranged on the upper surface of the partition, and an exhaust component arranged on the top of the nitrogen cylinder 6 for connecting to the malodorous gas cylinder 5, and cooperates with the driving component for use, the exhaust component is connected to the gas diluter 2, the malodorous gas monitor 3 and the fume hood 1.

[0026] like Figure 1 As shown, both sides of the fume hood 1 are made of transparent glass, and a cabinet door is provided at the bottom of the front side, and a storage space is provided inside the cabinet to facilitate the storage of the malodorous gas cylinder 5 for easy access and use. The functions of the gas diluter 2 include but are not limited to diluting high-concentration gas into low-concentration, accurately controlling the dilution ratio and the flow rate of the gas, etc.;

[0027] The calibration principle is: after the standard gas in the malodor gas cylinder 5 is diluted into gases of different concentrations, it is introduced into the malodor gas monitor 3. By comparing the concentration monitored by the malodor gas monitor 3 and the concentration of the standard gas, it is determined whether the malodor gas monitor 3 is within the error range. If it is within the range, no processing is required. If it is not within the error range, it is necessary to adjust the instrument correlation coefficient and other operations, and then introduce the standard gas again to see whether it is within the error range.

[0028] Note: The gas diluter 2 and the odorous gas monitor 3 are existing well-known technologies and are only cited here, and the specific structures are not described in detail.

[0029] Note: An exhaust fan (not shown) is provided in the exhaust duct of the fume hood 1 to quickly discharge the gas inside the cabinet. The upper surface of the nitrogen cylinder 6 is provided with an air inlet to facilitate the internal gas replenishment.

[0030] The driving assembly includes a driving motor 7 arranged on the side of the fume hood body 1 along the first direction, a screw 8 fixedly connected to the output end of the driving motor 7, a piston cylinder 9 arranged on the surface of the screw 8, an auxiliary push block 10 fixedly connected to the piston cylinder 9 away from the output end of the driving motor 7, and a first air inlet check valve 11 and a first air outlet check valve 12 arranged on the inner wall of the fume hood body 1.

[0031] like Figure 3 As shown, when the driving motor 7 is started to rotate forward, the screw 8 can be driven to rotate, and the piston cylinder 9 and the auxiliary push block 10 can be driven to move forward synchronously, so that the auxiliary push block 10 pushes the corner of the base 4, thereby driving the base 4 to rotate clockwise. When the auxiliary push block 10 is in a parallel state with the base 4, the driving motor 7 is started again to reverse, so that the auxiliary push block 10 is retracted, and the rotation adjustment of the base 4 is completed. The driving motor 7 is an existing well-known technology and is only referenced here. The specific structure will not be described in detail.

[0032] Note: When the piston cylinder 9 is compressed forward, the first air inlet check valve 11 in the compression space is in a non-conducting state, and the first air outlet check valve 12 is in a conducting state. The first air inlet check valve 11 behind the piston cylinder 9 is in a conducting state, and the first air outlet check valve 12 is in a non-conducting state. The external air flow enters its interior. When the piston cylinder 9 is compressed backward, the valve in the space where it is located is the same as when it is compressed forward.

[0033] Note: A roller is provided at one end of the auxiliary push block 10 close to the base. The purpose of this arrangement is that when the roller of the auxiliary push block 10 contacts the base 4, the resistance caused by pushing can be reduced, thereby improving the use effect.

[0034] The exhaust assembly includes a fixed cylinder 13 fixedly connected to the top of the nitrogen cylinder 6, an exhaust pipe 14 arranged inside the fixed cylinder 13, a connecting block 15 fixedly connected to the top of the exhaust pipe 14, a hose 16 arranged on the surface of the connecting block 15 for connecting to the air inlet end of the gas diluter 2, and an auxiliary pipe 17 fixedly connected to the surface of the connecting block 15 for connecting to the fixed cylinder 13. A buffer air bag 18 is provided at one end of the auxiliary pipe 17 close to the connecting block 15.

[0035] like Figure 1 like Figure 5As shown, an alarm and a control module are provided on one side of the fume hood 1, and a gas sensor (not numbered in the figure) is provided inside the exhaust pipe 14. When the sensor detects a lack of gas, a signal is sent to the alarm, and the alarm starts to sound, thereby alerting the staff.

[0036] like Figure 3 and Figure 4 As shown, when the piston cylinder 9 moves forward, the air inside it is compressed and enters the interior of the fixed cylinder 13 through the airflow chamber 20, so that the exhaust pipe 14 rises and separates from the malodorous gas cylinder 5. At this time, the base 4 rotates clockwise to replace the malodorous gas cylinder 5. When the piston cylinder 9 moves backward, the interior of the fixed cylinder 13 is continuously inflated, so that the exhaust pipe 14 rises higher. When the malodorous gas cylinder 5 is replaced, the gas inside the fixed cylinder 13 is released to the interior of the buffer airbag 18. At this time, the exhaust pipe 14 is connected to the malodorous gas cylinder 5 again. When nitrogen and malodorous gas enter the interior of the exhaust pipe 14 at the same time, the buffer airbag 18 releases gas to the interior of the connecting block 15, and the operation of the internal mechanism drives the stirring plate 33 to rotate, so as to facilitate the preliminary stirring and mixing of the gas entering therein.

[0037] A fixed layer 19 is provided on the surface of the nitrogen cylinder 6, and an air flow cavity 20 for connecting to the fixed cylinder 13 is provided inside the fume hood 1 and the fixed layer 19, and is connected to the piston cylinder 9. A second air intake check valve 21 and a first solenoid valve 22 are provided inside the fixed cylinder 13, and a second solenoid valve 23 is provided inside the exhaust pipe 14. The surfaces of the odorous gas cylinder 5 and the exhaust pipe 14 at one end away from the fixed cylinder 13 are provided with magnet blocks 24 that attract each other.

[0038] like Figure 1 As shown, magnet blocks 24 are provided on the surfaces of the exhaust pipe 14 and the malodorous gas cylinder 5. When the next malodorous gas cylinder 5 is replaced, the magnet block 24 can adsorb it on one end of the exhaust pipe 14 to avoid being unable to position the malodorous gas cylinder 5.

[0039] A third solenoid valve 25 is provided inside the top end of the malodorous gas cylinder 5, a compression spring 26 is provided inside the exhaust pipe 14 near one end of the malodorous gas cylinder 5, a closing block 27 is fixedly connected to the bottom of the compression spring 26, a return spring 28 is sleeved on the surface of one end of the exhaust pipe 14 extending deep into the fixed tube 13, and the exhaust pipe 14 is connected to the nitrogen cylinder 6 through a bellows.

[0040] Note: When the exhaust pipe 14 rises, the first solenoid valve 22 (point h is in a closed state, point g is in an open state), and the second air intake check valve 21 is in a non-conducting state. When the exhaust pipe 14 descends, the first solenoid valve 22 (point h is in an open state, point g is in a closed state), and the second air intake check valve 21 is in a conducting state. The external airflow enters the upper space. When the exhaust pipe 14 rises or falls, it can maintain connection with the nitrogen cylinder 6 through the bellows and will not be affected.

[0041] like Figure 6 As shown, through the compression spring 26 and the closing block 27 arranged in one end of the exhaust pipe 14 close to the malodorous gas cylinder 5, when the exhaust end of the malodorous gas cylinder 5 contacts the closing block 27, it is connected with the interior of the exhaust pipe 14. When the exhaust end of the malodorous gas cylinder 5 is separated from the closing block 27, the closing block 27 quickly closes the exhaust pipe 14 under the action of the compression spring 26. A sealing gasket is provided at the contact portion between the closing block 27 and the inner wall of the exhaust pipe 14 to reduce the leakage of internal gas.

[0042] The surface of the exhaust pipe 14 is fixedly connected with a bent pipe 29 and is connected to the interior thereof. The connecting block 15 includes an internal connecting cylinder 30, a driving rod 31 movably connected to the connecting cylinder 30 through a pin, a vertical rod 32 disposed at the end of the driving rod 31 away from the connecting cylinder 30 and connected by a bevel gear meshing, a stirring plate 33 disposed at the bottom of the vertical rod 32, and an auxiliary spring 34 sleeved on the surface of the driving rod 31. The inner wall of the connecting block 15 is provided with a fourth solenoid valve 35 and an air inlet hole. The bottom of the base 4 is octagonal, and the upper surface is provided with a plurality of grooves adapted to the malodorous gas cylinder 5. The upper surface of the base 4 is provided with a fixing hole, and is intermittently connected to the outer wall of the nitrogen cylinder 6.

[0043] Note: The drive motor 7, the first solenoid valve 22, the second solenoid valve 23, the third solenoid valve 25 and the fourth solenoid valve 35 are all controlled by the control module.

[0044] like Fig. 9 As shown, when the gas in the buffer airbag 18 enters the interior of the connecting block 15, the connecting tube 30 is squeezed and moved to the left. At this time, the driving rod 31 rotates under the cooperation of the pin and the internal thread of the connecting tube 30, and synchronously drives the vertical rod 32 and the stirring plate 33 to rotate. When the gas that squeezes the connecting tube 30 in the connecting block 15 is released, the connecting tube 30 is reset under the action of the auxiliary spring 34, and the stirring plate 33 is driven to rotate again.

[0045] Note: When the device is in the initial state, the first solenoid valve 22 (point h and point g are in a closed state), the second solenoid valve 23 (point a and point d are in a closed state, and points b and c are in an open state), the third solenoid valve 25 is in a closed state, the fourth solenoid valve 35 (point e and point f are in a closed state), the cushioning airbag 18 is in a semi-expanded state, and the driving assembly is pre-operated so that the exhaust pipe 14 is in a raised state.

[0046] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0047] In the utility model, the working steps of the device are as follows:

[0048] S1. When in use, the malodorous gas cylinder 5 is placed in the groove on the upper surface of the base 4, and an appropriate amount of nitrogen is stored in the nitrogen cylinder 6. The control module controls the first solenoid valve 22 (open at point h and closed at point g), and the reset spring 28 releases the compressed state, thereby squeezing the gas in the space below and allowing it to enter the interior of the buffer airbag 18. The exhaust pipe 14 is also connected to the malodorous gas cylinder 5. At this time, the third solenoid valve 25 and the fourth solenoid valve 35 (point f) are opened to allow the malodorous gas to enter the interior of the exhaust pipe 14, and the gas inside the buffer airbag 18 enters the interior of the connecting block 15, squeezing the connecting tube 30 inside it, and synchronously driving the vertical rod 32 and the stirring plate 33 to rotate through the driving rod 31, so as to facilitate the preliminary stirring of the gas entering the interior of the connecting block 15. When the gas inside the buffer airbag 18 is released, the fourth solenoid valve 35 (point e) is opened, and the auxiliary spring 34 drives the connecting tube 30 to reset, so that the stirring plate 33 stirs again, thereby increasing the stirring time of the malodorous gas and nitrogen.

[0049] S2. After the gas is mixed inside the connection block 15, it enters the interior of the gas diluter 2 from the hose 16. After being diluted and proportioned, the gas enters the interior of the odor gas monitor 3 through the pipe at the gas outlet end for calibration. The calibrated gas is discharged to the interior of the fume hood 1 through the gas outlet end of the odor gas monitor 3, and finally discharged through the exhaust fan inside the fume hood 1.

[0050] S3, when the next malodorous gas cylinder 5 needs to be replaced, the driving motor 7 is started to rotate forward and then reversed again, and the base 4 is pushed to rotate clockwise by the auxiliary push block 10, and the gas compressed by the piston cylinder 9 enters the interior of the fixed cylinder 13 again through the air flow chamber 20 (please refer to the above embodiment for the specific valve operation), so that the exhaust pipe 14 is in an elevated state, and when separated from the malodorous gas cylinder 5, the third solenoid valve 25 is in a closed state;

[0051] S4. At this time, it is necessary to flush the passage through which the malodorous gas passes to reduce the error in measuring the malodorous gas. Then, the control module controls the second solenoid valve 23 (points b and c are closed, and points a and d are opened), so that the nitrogen passes through the exhaust pipe 14, the elbow 29, the connecting block 15, the hose 16, the gas diluter 2 and the malodorous gas monitor 3, and finally is discharged to the inside of the fume hood 1;

[0052] S5. After completing step 4, repeat the above steps 1-4 again.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
