Description

Technical Field

[0001] This invention relates to the field of waste gas purification technology, specifically to an adsorption-type waste gas purifier for pet food processing. Background Technology

[0002] During the processing of pet food, some foods undergo changes in material form to achieve a shaping effect. For example, powdered food ingredients or solid dried ingredients need to be crushed and ground. However, the processing of powdered food ingredients can cause the powdery substances to escape and special odors to diffuse from the food processing area due to the influence of external vibration and the continuous movement of molecules, thus affecting the environment of the food processing area.

[0003] Existing food processing areas are equipped with exhaust gas purifiers. These purifiers are specifically designed to separate dispersed particles from the air in the food processing area. Essentially, they are filters used for particle treatment. During use, they achieve exhaust gas purification through processes such as air filtration. However, in actual use, the following problems still exist: Filtration, which essentially removes impurities from exhaust gases through adsorption, requires continuous gas delivery to ensure stable machine operation and uninterrupted exhaust gas purification. However, due to the continuous gas delivery, some impurities to be removed may be missed during the adsorption process, resulting in low-efficiency purification. Consequently, some impurities may remain in the purified exhaust gas after a single pass, requiring multiple additional purification processes and affecting purification efficiency.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing pet food processing waste gas purification methods. Summary of the Invention

[0005] The purpose of this invention is to provide an adsorption-type exhaust gas purifier for pet food processing, in order to solve the problem that the current adsorption-type exhaust gas purifiers for pet food processing have low purification efficiency when continuously transporting and purifying gas, and are prone to residual exhaust gas particles due to the high flow rate and velocity of the discharged gas.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adsorption-type exhaust gas purifier for pet food processing, comprising:

[0007] The first purification tank has a liquid chamber base that is connected to its bottom. A vent pipe for exhaust is also installed on the side of the liquid chamber base. The top of the first purification tank is equipped with a pump body for air intake control.

[0008] It also includes: a sealing partition plate, which is set in the middle of the first purification tank to divide its inner cavity. The sealing partition plate is also provided with a pressure accumulating purification component, which uses gas pressure to realize the residence purification of waste gas delivered to the inside of the first purification tank. The pressure accumulating purification component uses air pressure to realize the spray purification of the purification liquid in the liquid chamber base to purify the waste gas.

[0009] Preferably, the sealing partition plate is arranged in a funnel shape, wherein the inner cavity of the first purification tank above the sealing partition plate is a pressure storage chamber, which is used for the retention and pressure storage of waste gas.

[0010] Preferably, the pressure accumulator purification assembly includes a vertical pipe fixed in the middle of the first purification tank, and a sealing element is movably installed on the outer wall of the middle section of the vertical pipe, with an elastic element fixed between the top of the sealing element and the outer wall of the vertical pipe.

[0011] The sealing element controls the opening and closing of the middle part of the sealing partition plate by changing the air pressure inside the accumulator chamber.

[0012] Preferably, the lower end of the vertical tube is fixed inside the liquid storage chamber, the liquid storage chamber is fixed inside the liquid chamber base, the lower outer wall of the vertical tube inside the liquid storage chamber is hollowed out, the internal hydraulic pressure of the liquid storage chamber is controlled by the lifting and lowering of the sealing element, and the upper end of the vertical tube located on the inner wall of the top of the first purification tank is connected to a spray assembly.

[0013] Preferably, the sealing element is arranged in an "I" shape, wherein the sealing element and the vertical pipe form a relative lifting structure, and the upper and lower outer walls of the sealing element are respectively fitted with the inner wall of the middle part of the sealing partition plate and the inner wall of the liquid storage cavity in a sliding sealing structure.

[0014] Preferably, a one-way adjustable valve body is provided at the junction of the middle part of the spray assembly and the upper end of the vertical pipe, which enables the one-way delivery of liquid from the vertical pipe to the spray assembly;

[0015] The valve body includes a liquid seal plate that is dynamically mounted in the middle of the spray assembly, and the liquid seal plate is limited by an elastic telescopic rod fixed in the middle of the spray assembly.

[0016] Preferably, the maximum liquid level inside the liquid chamber base is located between the upper end of the air guide tube and the upper end of the liquid storage chamber, the horizontal plane of the upper end of the air guide tube is above the horizontal plane of the upper end of the liquid storage chamber, and the air guide tube is set in an "L" shape.

[0017] Preferably, a pressure chamber is also installed through the outer wall of the pressure storage chamber on the upper layer of the first purification tank. A lifting and sealing air seal plate is installed in the pressure chamber. The air seal plate is controlled to descend by an electromagnetic drive component at the top of the inner wall of the pressure chamber. The electromagnetic drive component is used in conjunction with a pressure sensor in the first purification tank.

[0018] Preferably, the liquid chamber base is configured with a double inner cavity that is sealed and separated on the left and right sides. The right cavity is connected to the first purification tank, and the top of the left cavity is connected to the second purification tank. The top of the second purification tank is provided with a partition sheet for one-way exhaust control, so that the gas is discharged from the inside of the second purification tank. The second purification tank is provided with a purification component.

[0019] The lower end of the gas guide tube is located below the surface of the purification liquid in the left cavity of the liquid chamber base. At the same time, the gas guide tube is used for unidirectional gas transport from the first purification tank to the second purification tank.

[0020] Preferably, a water level control valve is provided between the left and right double inner cavities of the liquid cavity base to control the water level synchronization, and a drain valve is connected to the outer wall of the left and right inner cavities of the liquid cavity base.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: This adsorption-type exhaust gas purifier for pet food processing, during continuous gas delivery, utilizes the principle of pressure storage to intercept exhaust gas, thereby improving the adsorption-type purification efficiency of exhaust gas through exhaust gas interception and purification and increasing pressure. The specific details are as follows:

[0022] 1. The first purification tank is internally divided and sealed by a sealing partition plate and sealing components. The gas is temporarily stored in the pressure accumulator chamber in the upper part of the first purification tank. The sealing components are positioned by the installation of elastic components. When the waste gas is continuously introduced into the pressure accumulator chamber, the internal air pressure of the pressure accumulator chamber increases and the air pressure drives the sealing components to move. During this process, the pressure accumulator chamber intercepts the waste gas and increases the air pressure to achieve adsorption purification of the waste gas through spraying, thereby improving the purification efficiency of the waste gas.

[0023] Furthermore, when the pressure accumulator traps the waste gas, it does not affect the continuous introduction of the gas into the first purification tank. By increasing the gas pressure, the activity of impurity particles in the waste gas is increased, accelerating the reaction rate of subsequent waste gas treatment. At the same time, the increase in gas pressure is used to realize the bottom-up transportation and spraying operation of the purified liquid in the liquid chamber base.

[0024] Furthermore, the pressure chamber, which is equipped with a matching system, and the air seal plate inside which is driven to rise and fall by an electromagnetic drive, simultaneously accumulate pressure in the upper half of the pressure accumulator chamber inside the first purification tank, thereby increasing the amount of waste gas intercepted. At the same time, when the intercepted waste gas is discharged through the middle of the sealing partition plate, the pressure chamber acts synchronously, further accelerating the flow rate and efficiency of the gas being discharged from the gas guide pipe.

[0025] 2. A gas guide pipe and a liquid chamber base are installed simultaneously. When the gas is discharged through the gas guide pipe, the impurity particles in the waste gas are treated by the purification liquid. A second purification tank with one-way gas discharge is also installed. After the waste gas in the first purification tank undergoes the first interception purification treatment, this part of the waste gas is introduced into the second purification tank for a second interception purification treatment.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figures 1-7The present invention provides a technical solution: an adsorption-type exhaust gas purifier for pet food processing, comprising: a first purification tank 1, the bottom of which is connected to a liquid chamber base 2, wherein a gas guide pipe 5 for exhaust is also installed through the side of the liquid chamber base 2, and a pump body 3 for air intake control is provided at the top of the first purification tank 1; in the above solution, the pump body 3 is used to pressurize the gas and continuously deliver it to the first purification tank 1, and the gas that has completed the first purification treatment inside the first purification tank 1 is discharged through the gas guide pipe 5.

[0038] This technical solution also includes: a sealing partition plate 4, which is set in the middle of the first purification tank 1 to divide its internal cavity. The sealing partition plate 4 is also equipped with a pressure accumulating purification component, which uses gas pressure accumulation to achieve the residence-type purification of waste gas delivered to the inside of the first purification tank 1. The pressure accumulating purification component uses air pressure to spray the purification liquid in the liquid chamber base 2 to purify the waste gas. The sealing partition plate 4 is set in a funnel shape, and the inner cavity of the first purification tank 1 above the sealing partition plate 4 is a pressure accumulating chamber, which is used for the residence and pressure accumulation of waste gas. In this solution, when the gas is pressurized and introduced, the gas is first introduced into the pressure accumulating chamber of the first purification tank 1. Due to the separation treatment by the sealing partition plate 4, the pressurized gas introduced into the first purification tank 1 is continuously accumulated and compressed, which increases the air pressure inside the first purification tank 1. The increase in air pressure drives the pressure accumulating purification component to operate.

[0039] In the above technical solution, the pressure accumulator purification component includes a vertical pipe 6 fixed in the middle of the first purification tank 1, and a sealing element 8 is movably installed on the outer wall of the middle section of the vertical pipe 6. An elastic element 9 is fixed between the top of the sealing element 8 and the outer wall of the vertical pipe 6. The sealing element 8 controls the opening and closing of the middle part of the sealing partition plate 4 by changing the air pressure inside the pressure accumulator chamber. The lower end of the vertical pipe 6 is fixed inside the liquid storage chamber 7, and the liquid storage chamber 7 is fixed inside the liquid chamber base 2. The lower outer wall of the vertical pipe 6 inside the liquid storage chamber 7 is hollowed out. The internal hydraulic pressure of the liquid storage chamber 7 is controlled by the lifting and lowering of the sealing element 8. The upper end of the vertical pipe 6 located on the top inner wall of the first purification tank 1 is connected to the spray component 10. The sealing element 8 is set in an "I" shape. The sealing element 8 and the vertical pipe 6 form a relative lifting structure. The upper and lower outer walls of the sealing element 8 are respectively fitted and slidingly sealed with the inner wall of the middle part of the sealing partition plate 4 and the inner wall of the liquid storage chamber 7.

[0040] In this technical solution, the air pressure in the accumulator chamber of the first purification tank 1 continuously increases. The air pressure causes the sealing element 8 to move downward, and the elastic element 9 installed on the top of the sealing element 8 expands. During this process, the high elasticity of the elastic element 9 causes the air pressure inside the first purification tank 1 to continuously increase. When the air pressure reaches the threshold, the sealing element 8 will move downward. As the sealing element 8 moves, the lower end of the "I" shape of the sealing element 8 first moves to the liquid storage chamber 7, pressurizing the purification liquid inside the liquid storage chamber 7. Under the action of external pressure, the purification liquid is introduced into the vertical pipe 6 and the spray assembly 10, and discharged from the location of the spray assembly 10. The atomized water body is used to adsorb and purify the pressurized gas inside the first purification tank 1. During this process, the first purification tank 1 continuously introduces waste gas and intercepts and pressurizes the waste gas to promote purification. As the air pressure inside the first purification tank 1 increases and the sealing element 8 continues to descend, the middle of the sealed partition plate 4 is opened. Under the action of air pressure, the gas is introduced into the gas guide pipe 5, and the purified gas is discharged from the gas guide pipe 5.

[0041] The aforementioned spray assembly 10 includes pipes and nozzles, and can be used for spraying water.

[0042] At the same time, it adopts such as Figure 5 As shown, in this technical solution, a one-way adjustable valve body is provided at the junction of the middle of the spray assembly 10 and the upper end of the vertical pipe 6. The valve body realizes the one-way delivery of liquid from the vertical pipe 6 to the spray assembly 10. The valve body includes a liquid seal plate 1002 that is movably installed in the middle of the spray assembly 10. The liquid seal plate 1002 is limited by an elastic telescopic rod 1001 fixed in the middle of the spray assembly 10. The function of the elastic telescopic rod 1001 and the liquid seal plate 1002 is to realize the one-way delivery of the purification liquid from the vertical pipe 6 and the spray assembly 10, and to prevent the backflow of the purification liquid and the filling of gas inside the vertical pipe 6 caused by gas pressure.

[0043] Further, such as Figure 6 and Figure 7As shown: The maximum liquid level inside the liquid chamber base 2 is located between the upper end of the air guide pipe 5 and the upper end of the liquid storage chamber 7. The horizontal plane of the upper end of the air guide pipe 5 is above the horizontal plane of the upper end of the liquid storage chamber 7. The air guide pipe 5 is set in an "L" shape. The left and right sides of the liquid chamber base 2 are set as sealed double inner cavities. The right cavity is connected to the first purification tank 1, and the top of the left cavity is connected to the second purification tank 11. The top of the second purification tank 11 is provided with a one-way exhaust control partition plate 12, which allows gas to be discharged from the inside of the second purification tank 11. The second purification tank 11 is equipped with a purification component. The lower end of the air guide pipe 5 is located below the liquid level of the purification liquid in the left cavity of the liquid chamber base 2. The gas guide pipe 5 is used for unidirectional gas transport from the first purification tank 1 to the second purification tank 11. The gas guide pipe 5 and the second purification tank 11 are installed in conjunction. When the gas is discharged through the gas guide pipe 5, the gas purified at the first stage is introduced into the second purification tank 11 for secondary interception and storage. The gas is then purified at the second stage by the purification components inside the second purification tank 11. The purification components include, but are not limited to, photocatalytic and ultraviolet lamp sterilization components. The gas capacity inside the second purification tank 11 is greater than the capacity of the upper half of the pressure storage chamber of the first purification tank 1, so that the gas can be discharged after secondary purification in the second purification tank 11 through subsequent gas introduction.

[0044] In the above technical solution, a water level control valve 13 is provided between the left and right double inner cavities of the liquid cavity base 2 to control the water level synchronously, and a drain valve 14 is connected to the outer wall of the left and right inner cavities of the liquid cavity base 2 to facilitate draining.

[0045] The purification liquid is formulated according to the waste gas generated in different food processing processes to achieve physical adsorption of powder impurities and chemical reaction treatment of molecular substances in the waste gas.

[0046] Meanwhile, the pressure accumulator purification component can also be equipped with a gas accumulator inside the first purification tank 1, which is sealed by a solenoid valve, and a supporting structure for the purification treatment of waste gas by a liquid pump structure to transport the purification liquid, thereby achieving waste gas interception purification and improving purification efficiency.

[0047] Example 2: This example is based on Example 1, and adopts the following... Figure 8 and Figure 9As shown, a pressure chamber 15 is further installed through the outer wall of the accumulator chamber on the upper part of the first purification tank 1. A lifting and sealing air seal plate 16 is installed in the pressure chamber 15. The air seal plate 16 is controlled to descend by an electromagnetic drive 17 at the top of the inner wall of the pressure chamber 15. The electromagnetic drive 17 is used in conjunction with the air pressure sensor in the first purification tank 1. The installation of the pressure chamber 15 is such that when the gas is pressurized and trapped in the accumulator chamber in the upper half of the first purification tank 1, the pressure chamber 15 is pressurized synchronously, increasing the maximum gas pressure and gas trapping capacity inside the first purification tank 1. When the gas pressure reaches the threshold and the purified gas is discharged through the sealing partition plate 4, the electromagnetic drive 17 inside the pressure chamber 15, under the action of the sensor and the matching integrated circuit, drives the air seal plate 16 to move faster, introducing the pressurized gas inside the pressure chamber 15 into the first purification tank 1, so that the pressurized gas is discharged more quickly from the sealing partition plate 4 under the action of external pressure.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
