Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of metrology, in particular to a glass metering assembly and an ozone generating device. BACKGROUND

[0002] Ozone is a common sterilization and disinfection method in the food industry or the pharmaceutical industry. In some food factories or pharmaceutical factories, ozone generating devices are usually configured. When compressed air and water are respectively introduced into the reaction tank of the ozone generating device, the high-voltage electrode in the reaction tank can generate a high-voltage electric field under the condition of power-on, so that the oxygen molecules (O2) in the introduced compressed air and water can be ionized into single oxygen atoms (O) and oxygen molecule ions (O2) under the action of the high-voltage electric field. The generated oxygen atoms and oxygen molecule ions will further react with oxygen molecules in the high-voltage electric field to generate ozone (O3) for sterilization and disinfection. + 、O2 -

[0003] In actual application, the ozone generation amount is often closely related to the flow of the introduced compressed air. Therefore, a glass flowmeter is usually arranged in the gas inlet pipeline of the ozone generating device, so that the glass flowmeter can accurately control the inflow amount of the compressed air to ensure that the ozone generating device can achieve the predetermined ozone production amount.

[0004] However, when the air flow of the compressed air in the gas inlet pipeline is large, the float in the glass flowmeter will quickly rise, causing the float to easily hit the glass tube and causing the ozone generating device to fail to operate normally. In order to solve the above technical problems, a glass rotor flowmeter with a buffer structure is disclosed in Chinese document No. CN 211954278 U, which sets an elastic baffle and a spring at the gas outlet of the fixed rod to effectively prevent the float from hitting the glass tube.

[0005] However, since the above-mentioned glass rotor flowmeter realizes the soft connection of the elastic baffle through the spring, under the condition of repeated impact of a large air flow for many times, the spring is prone to overload, which shortens the service life of the spring. CONTENT OF THE UTILITY MODEL

[0006] The purpose of the present disclosure is to overcome the deficiencies in the prior art, provide a glass metering assembly and an ozone generating device which can better weaken the impact force of the float on the elastic member, not only avoid the phenomenon that the float hits the glass tube, but also improve the service life of the elastic member and facilitate users to disassemble, replace or repair the damaged glass rotor flowmeter, and reduce maintenance costs.

As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0032] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in combination with specific embodiments:

[0033] Please refer to Figures 1 to 3The glass metering assembly 100 of one embodiment comprises a glass rotameter 110, which comprises a float 111, a fixed rod 112, a glass tube 113 and an elastic member 114. The fixed rod 112 is arranged in the glass tube 113, and the float 111 is movably arranged on the fixed rod 112. When compressed air enters the glass tube 113, the float 111 moves up and down along the fixed rod 112 under the push of external airflow to measure the flow rate of the compressed air. The elastic member 114 is arranged on the end of the fixed rod 112 away from the float 111, so that the added elastic member 114 can weaken the impact force of the float 111 on the glass tube 113, effectively preventing the float 111 from damaging the glass tube 113. The glass metering assembly 100 further comprises a buffer pipeline assembly 120. The buffer pipeline assembly comprises a bent air inlet pipe 121 and an air outlet pipe 122 connected in communication. The bent air inlet pipe 121 is formed with a buffer bending portion 1211, which is connected to the air outlet pipe 122 through the glass tube 113. The air inlet end of the glass tube 113 is detachably threadedly connected to the buffer bending portion 1211, and the air outlet end of the glass tube 113 is detachably threadedly connected to the air outlet pipe 122.

[0034] It can be understood that, since the bent air inlet pipe 121 is formed with the buffer bending portion 1211, which is connected to the air outlet pipe 122 through the glass tube 113, the buffer bending portion 1211, the glass tube 113 and the air outlet pipe 122 are connected in communication with each other. When the bent air inlet pipe 121 is connected to external compressed air, and the air outlet pipe 122 is connected to the ozone reaction tank 200, the compressed air enters the bent air inlet pipe 121, then flows through the glass tube 113 and the air outlet pipe 122 in sequence, and finally enters the ozone reaction tank 200 through the air outlet pipe 122. In this way, the added buffer bending portion 1211 can better buffer and decompress the compressed air with a larger airflow, so as to slow down the rising speed of the float 111, thereby weakening the impact force of the float 111 on the elastic member 114. Not only is the phenomenon of the float 111 damaging the glass tube 113 avoided, but also the probability of the elastic member 114 being overloaded is reduced, thereby prolonging the service life of the elastic member 114.

[0035] Please refer to Figure 2 and Figure 3 Further, since the air inlet end of the glass tube 113 is detachably threadedly connected to the buffer bending portion 1211, and the air outlet end of the glass tube 113 is detachably threadedly connected to the air outlet pipe 122, the user can conveniently disassemble or replace the damaged glass rotameter 110, thereby reducing the maintenance cost.

[0036] Please refer to Figure 1 and Figure 2In one of the embodiments, the buffer bending part 1211 comprises a first bending buffer sub-part 1211a and a second bending buffer sub-part 1211b connected with each other, the second bending buffer sub-part 1211b communicates with the air inlet end of the glass tube 113, and the first bending buffer sub-part 1211a is used to communicate with the external compressed air, so that the buffer bending part 1211 has two buffer parts, which can satisfy the better buffer and pressure reduction of the compressed air with large air flow, ensure the transmission efficiency of the compressed air, and effectively avoid the influence of the compressed air transmission efficiency caused by the large number of bending buffer sub-parts of the buffer bending part 1211.

[0037] Please refer to Figure 2 In a preferred embodiment, the first bending buffer sub-part 1211a is a right-angle air inlet buffer sub-part, which can preliminarily buffer and reduce the pressure of the compressed air with large air flow, and better weaken the air pressure entering the glass tube 113.

[0038] Further, please refer to Figure 2 In a preferred embodiment, the second bending part is a U-shaped air inlet buffer sub-part, which has a high air inlet end and a low air outlet end, and the air inlet end of the glass tube 113 communicates with the low air outlet end, so that the added U-shaped air inlet buffer sub-part can buffer and reduce the pressure of the compressed air with large air flow twice, further weaken the air pressure entering the glass tube 113, better weaken the impact force of the float 111 on the elastic member 114, and thus improve the service life of the elastic member 114.

[0039] Further, please refer to Figure 1 and Figure 2 In one of the embodiments, the glass metering assembly 100 further comprises a pressure reducing valve 130 arranged on the bending air inlet pipe 121, so that the added pressure reducing valve 130 can pre-buffer and reduce the pressure of the compressed air with large air flow, especially in cooperation with the use of the right-angle air inlet buffer sub-part and the U-shaped air inlet buffer sub-part, which can better weaken the air pressure entering the glass tube 113, better weaken the impact force of the float 111 on the elastic member 114, and thus better improve the service life of the elastic member 114.

[0040] In one of the embodiments, please refer to Figures 2 to 4The glass tube 113 comprises an upper base 115, a lower base 116 and a tube body, and the tube body is formed with a containing cavity 1131, and opposite ends of the containing cavity 1131 are formed with an air inlet end and an air outlet end respectively, the air inlet end is communicated with the bent air inlet tube 121, and the air outlet end is communicated with the air outlet tube 122, so that the glass tube 113, the bent air inlet tube 121 and the air outlet tube 122 are communicated, and the compressed air can enter the air inlet end of the glass tube 113 from the bent air inlet tube 121, and then enter the containing cavity 1131 from the air inlet end of the glass tube 113, and the fixed rod 112 is located in the containing cavity 1131, so that the float 111 can move up and down along the fixed rod 112 under the pushing of external airflow, thereby measuring the flow of the compressed air.

[0041] It can also be understood that, since the upper base 115 is arranged on the air outlet end, the upper base 115 is screwed with the air outlet tube 122 through a first flange, so as to realize detachable screw connection between the air outlet end of the glass tube 113 and the air outlet tube 122; the lower base 116 is arranged on the air inlet end, and the lower base 116 is screwed with the bent air inlet tube 121 through a second flange, so as to realize detachable screw connection between the air inlet end of the glass tube 113 and the buffer bent part 1211, which facilitates users to disassemble or replace the damaged glass rotor flowmeter 110, and reduces the maintenance cost.

[0042] In one embodiment, the elastic member 114 is a spring, and the spring is fixedly sleeved on one end of the fixed rod 112 close to the air outlet tube 122, so that the spring can wrap the fixed rod 112, so as to ensure that the spring can provide more uniform and reliable buffer force for the float 111, and better prevent the float 111 from hitting the glass tube 113.

[0043] In one embodiment, the thickness of the spring gradually decreases from one end close to the air outlet tube 122 to one end away from the air outlet tube 122, so that the connection strength of the spring close to the air outlet tube 122 is higher, and the one end of the spring away from the air outlet tube 122 can be deformed faster, so as to provide better buffer effect for the float 111, so that the spring has better connection strength under the action of larger airflow, and also ensures that the spring can provide faster buffer effect for the float 111, and better prevents the float 111 from hitting the glass tube 113.

[0044] It can be understood that the general spring on the market is a metal spring, mainly because the metal spring has good structural strength to ensure that the spring is not prone to breakage under repeated use conditions, that is, the service life of the spring is better ensured. However, since the float 111 is also made of metal, when the float 111 collides with the spring, the float 111 is prone to wear, which causes the glass rotor flowmeter 110 to be prone to inaccurate measurement over a long period of time. Therefore, in one embodiment, the outer peripheral wall of the spring is covered with an elastic rubber sleeve, so that the added elastic rubber sleeve can effectively reduce the wear between the float 111 and the metal spring. In this way, while ensuring the accuracy of the glass rotor flowmeter 110 in long-term measurement, the service life of the spring is also ensured.

[0045] Please refer to Figure 1 and Figure 2 The present disclosure also provides an ozone generating device 10 comprising the glass metering assembly 100 of any of the above embodiments. It can be understood that the ozone generating device 10 comprises a control box 300, an ozone reaction tank 200 and the glass metering assembly 100 of the present disclosure. The control module of the control box 300 is electrically connected to the electrode of the ozone reaction tank 200, and the gas inlet of the ozone reaction tank 200 is in communication with the gas outlet pipe 122 of the glass metering assembly 100, so that the glass metering assembly 100 can communicate with the ozone reaction tank 200 through the gas outlet pipe 122, and the compressed air of the gas outlet pipe 122 of the glass metering assembly 100 can enter the ozone reaction tank 200. Then, under the condition of power on, the ozone reaction tank 200 can ionize the incoming compressed air to obtain ozone gas, and finally the ozone gas is sent to the required work station through the outlet of the ozone reaction tank 200 to complete the sterilization and disinfection operation. In addition, since the glass metering assembly 100 is additionally provided with a buffer bending portion 1211, it can better buffer and decompress the compressed air of a larger air flow, not only avoiding the phenomenon of the float 111 breaking the glass tube 113, but also reducing the probability of the elastic member 114 being overloaded, thereby improving the service life of the elastic member 114.

[0046] In one embodiment, the ozone generating device 10 further comprises a cooling pipeline 400, which is in communication with the ozone reaction tank 200, so that liquid water can enter the ozone reaction tank 200 through the cooling pipeline 400 to achieve better cooling of the electrode of the ozone reaction tank 200, thereby ensuring the normal operation of the ozone reaction tank 200.

[0047] It should be noted that the ionization of compressed air or water by the ozone reaction tank 200 is a prior art, and therefore is not described in detail in the present disclosure.

[0048] Compared with the prior art, the present disclosure has at least the following advantages:

[0049] 1) Since the bending air inlet pipe 121 is formed with a buffer bending part 1211, which is communicated with the glass pipe 113 and the air outlet pipe 122, when the bending air inlet pipe 121 is communicated with the external compressed air and the air outlet pipe 122 is communicated with the ozone reaction tank 200, the compressed air will enter the bending air inlet pipe 121, then flow through the glass pipe 113 and the air outlet pipe 122 in turn, and finally enter the ozone reaction tank 200 through the air outlet pipe 122, so that the added buffer bending part 1211 can better buffer and decompress the compressed air of larger airflow, so as to slow down the rising speed of the float 111, thereby weakening the impact force of the float 111 on the elastic member 114, avoiding the phenomenon that the float 111 hits the glass pipe 113, and reducing the probability of overload of the elastic member 114, thereby prolonging the service life of the elastic member 114.

[0050] 2) Since the air inlet end of the glass pipe 113 is detachably screwed with the buffer bending part 1211, and the air outlet end of the glass pipe 113 is detachably screwed with the air outlet pipe 122, it is convenient for the user to disassemble or replace the damaged glass rotameter 110, thereby reducing the maintenance cost.

[0051] The above-mentioned embodiments only express several embodiments of the present disclosure, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the disclosed patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present disclosure, a number of modifications and improvements can be made, which are all within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the appended claims.
