Description

Technical Field

[0001] This utility model relates to the field of oxygen-enriched combustion technology, specifically to an oxygen-enriched combustion air supply device for a cremator. Background Technology

[0002] Oxygen-enriched combustion uses air with a higher oxygen content than the air itself to assist combustion. The advantages of using oxygen-enriched air include: faster combustion rate, more complete fuel combustion, and reduced smoke emissions and heat loss.

[0003] In related technologies, fans and oxygen generators are often used to deliver oxygen-enriched air to the burner. However, this delivery method is not flexible enough. When the demand for oxygen increases, the supply of oxygen-enriched air may be insufficient. When the inlet valve of the burner is closed, the pressure in the pipeline delivering the oxygen-enriched air increases, and the oxygen produced by the oxygen generator cannot be used in time, resulting in a waste of some oxygen. Utility Model Content

[0004] The purpose of this invention is to provide an oxygen-enriched combustion air supply device for a cremator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oxygen-enriched combustion air supply device for a cremator, comprising a housing, wherein an oxygen-enriched membrane oxygen generator and a fan are installed inside the housing, and an exhaust pipe is installed on the right side of the housing, wherein the exhaust pipe is connected to the oxygen-enriched membrane oxygen generator and the fan, the fan accelerates airflow, and the oxygen-enriched membrane oxygen generator delivers oxygen to the exhaust pipe, thereby increasing the oxygen content in the air, improving the combustion rate of the cremator, and reducing resource consumption;

[0006] The circulation pipe is connected to the discharge pipe, and the other end of the circulation pipe is connected to the air inlet of the blower. A valve is installed on the circulation pipe. When the air inlet valve of the cremator is closed, the pressure in the discharge pipe increases. At this time, the valve is opened, and the oxygen-enriched air can flow back to the air inlet of the blower, reducing the waste of oxygen-enriched air.

[0007] The cylindrical shell is installed on the inner wall of the box. A corrugated airbag is connected inside the cylindrical shell. An electric cylinder is installed on the cylindrical shell and connected to the left end of the corrugated airbag. The corrugated airbag is connected to the oxygen-enriched membrane oxygen generator and the discharge pipe. When the demand for oxygen-enriched air decreases, oxygen can be temporarily stored in the corrugated airbag. When more oxygen is needed, the corrugated airbag discharges oxygen, realizing flexible oxygen supply and meeting different combustion needs.

[0008] Furthermore, a connecting sleeve is installed on the left side of the box, and three bend seats arranged in a ring are provided on the left side of the box. A support frame is installed in the bend seat, and a filter is connected to the support frame. The filter can filter some particles in the air, reduce impurities in the oxygen-enriched air, and also reduce dust adhering to the fan and oxygen-enriched membrane oxygen generator.

[0009] Furthermore, several support bars are fixedly connected inside the support frame. The support bars can support the filter element, prevent excessive deformation of the filter element, and extend the service life of the filter element. The support frame is made of plastic and can be bent, making it easy and quick to remove and replace the filter element.

[0010] Furthermore, the corrugated airbag is connected to a first delivery pipe and a second delivery pipe, and the first delivery pipe and the second delivery pipe are respectively connected to the oxygen-enriched membrane oxygen generator and the discharge pipe. The first delivery pipe and the second delivery pipe are connected to a first one-way valve and a second one-way valve to ensure that the corrugated airbag can only draw oxygen generated by the oxygen-enriched membrane oxygen generator and to ensure that oxygen is only delivered to the discharge pipe.

[0011] Furthermore, the left end of the corrugated airbag is provided with a push-pull plate, which is fixedly connected to the piston rod of the electric cylinder to improve the stability of the corrugated airbag compression, ensure that the corrugated airbag will not bend during the compression process, and also to stretch the corrugated airbag.

[0012] Furthermore, an anemometer is installed on the upper surface of the discharge pipe, which can be used to view the flow rate of the oxygen-enriched air. When adjusting the flow rate of the oxygen-enriched air, the flow rate can be seen more intuitively.

[0013] Furthermore, the discharge pipe is connected to a replenishment pipe, which is used to connect to an oxygen cylinder. If a high oxygen concentration is required, the valve of the oxygen cylinder can be opened to meet the demand for high-concentration oxygen supply.

[0014] Furthermore, a fixing frame is fitted onto the electric cylinder, and the fixing frame is connected to the housing to ensure that the electric cylinder stably compresses and stretches the corrugated airbag.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) Part of the oxygen produced by the oxygen-enriched membrane oxygen generator is stored in the corrugated air bag. When the demand for oxygen-enriched air decreases, the corrugated air bag can be stretched to collect oxygen and reduce oxygen waste. When the demand for oxygen-enriched air increases, the electric cylinder compresses the corrugated air bag to send oxygen into the air, increase the oxygen concentration, and realize flexible supply of oxygen-enriched air.

[0017] (2) When the air pressure inside the exhaust pipe increases, the valve can be opened to release the pressure. The oxygen-enriched air flows along the circulation pipe to the air inlet of the blower, where the oxygen-enriched air can be recycled, reducing the waste of oxygen-enriched air and avoiding unnecessary waste while ensuring combustion efficiency.

[0018] (3) The support frame and filter can rotate. When there are many impurities attached to the filter, rotating the filter can align the part with fewer impurities with the fan and oxygen-enriched membrane oxygen generator, ensuring low air flow resistance. The filter does not need to be disassembled when cleaning the filter, making it more convenient to use. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 1-5 This utility model provides a technical solution: an oxygen-enriched combustion air supply device for a cremator, including a box body 1, two boxes 5 are rotatably installed on the box body 1, and transparent plates 6 are installed on the boxes 5. The transparent plates 6 are made of glass or acrylic, and the fan 11 and the oxygen-enriched membrane oxygen generator 12 can be viewed through the glass or acrylic. A handle 7 is installed on the boxes 5.

[0028] The housing 1 is equipped with an oxygen-enriched membrane oxygen generator 12 and a fan 11. The oxygen-enriched membrane oxygen generator 12 achieves oxygen enrichment through the selective permeation characteristics of different gas components in the air by the polymer oxygen-enriched membrane. When air passes through the oxygen-enriched membrane, oxygen molecules will preferentially permeate through the membrane material because the permeation rate of oxygen molecules is higher than that of nitrogen molecules, while nitrogen and other gas components are blocked. By physically compressing the air and making it pass through multiple layers of oxygen-enriched membrane, the oxygen concentration in the finally collected gas can be increased to about 30%, which is higher than the normal oxygen content of 21% in the air.

[0029] When a higher oxygen concentration is required, the oxygen-enriched membrane oxygen generator 12 can also be replaced by a molecular sieve oxygen generator. The molecular sieve oxygen generator discharges high-purity oxygen (oxygen content of more than 90%) to meet the demand for high-purity oxygen.

[0030] The right side of the housing 1 is equipped with an exhaust pipe 3, which is connected to the oxygen-enriched membrane oxygen generator 12 and the fan 11. The exhaust pipe 3 delivers oxygen-enriched air out, which can be used by the cremator or to provide oxygen-enriched air to other burners.

[0031] A circulation pipe 13 is connected to an exhaust pipe 3. The other end of the circulation pipe 13 is connected to the air inlet of a fan 11. The motor of the fan 11 is on the right side, and the air inlet of the fan 11 is on the left side. A valve 14 is installed on the circulation pipe 13. When the valve 14 of the pipe connected to the exhaust pipe 3 is closed, the air pressure in the exhaust pipe 3 increases. At this time, the valve 14 can be opened to release the pressure in the exhaust pipe 3. The oxygen-enriched air flows from the circulation pipe 13 into the air inlet of the fan 11 and can be reused, reducing the waste of oxygen-enriched air.

[0032] Valves 14 can be installed between the blower 11 and the oxygen-enriched membrane oxygen generator 12 and the discharge pipe 3 respectively to achieve flow control of air and oxygen;

[0033] A cylindrical shell 16 is installed on the inner wall of the housing 1. A corrugated airbag 21 is connected inside the cylindrical shell 16. An electric cylinder 15 is installed on the cylindrical shell 16 and connected to the left end of the corrugated airbag 21. The corrugated airbag 21 is connected to the oxygen-enriched membrane oxygen generator 12 and the discharge pipe 3. The corrugated airbag 21 is made of wear-resistant materials such as rubber (composite) or polymer synthetic materials, and can be repeatedly compressed. The electric cylinder 15 can accelerate the discharge of oxygen by squeezing the corrugated airbag 21. The electric cylinder 15 can draw oxygen by pulling the corrugated airbag 21. When the oxygen demand is low, some oxygen can be sent into the corrugated airbag 21.

[0034] In this embodiment, as Figure 2As shown, a connecting sleeve 4 is installed on the left side of the box 1. Three bending seats 8 are arranged in a ring on the left side of the box 1. A support frame 9 is installed in the bending seat 8. A filter 10 is connected to the support frame 9. The filter 10 can be made of PET polyester fiber nonwoven fabric, PTFE coated polyester nonwoven fabric, wood pulp fiber filter paper, etc. The support frame 9 is made of plastic and can be bent. The bending support frame 9 is separated from the bending seat 8, and the support frame 9 and filter 10 can be quickly removed for easy replacement. When the air filtration requirements are high, a filter with better filtration effect can be used. The filter is connected to the connecting sleeve 4. The connecting sleeve 4 has holes to facilitate fixing to the filter with screws and nuts.

[0035] In this embodiment, as Figure 3 As shown, several support bars 23 are fixedly connected inside the support frame 9. The support bars 23 support the filter 10. When the fan 11 and the oxygen-enriched membrane oxygen generator 12 draw air, the support bars 23 prevent the filter 10 from being over-deformed and prevent the filter 10 from losing its filtering function.

[0036] In this embodiment, as Figure 4 As shown, the corrugated airbag 21 is connected to a first delivery pipe 17 and a second delivery pipe 20, and the first delivery pipe 17 and the second delivery pipe 20 are respectively connected to the oxygen-enriched membrane oxygen generator 12 and the discharge pipe 3. The first delivery pipe 17 and the second delivery pipe 20 are connected to a first one-way valve 18 and a second one-way valve 19. When the corrugated airbag 21 draws oxygen, the second one-way valve 19 can prevent the oxygen-enriched air in the discharge pipe 3 from being drawn out. When the oxygen in the corrugated airbag 21 is discharged, the first one-way valve 18 can prevent the oxygen from flowing into the oxygen-enriched membrane oxygen generator 12.

[0037] In this embodiment, as Figure 5 As shown, the left end of the corrugated airbag 21 is provided with a push-pull plate 22, which is fixedly connected to the piston rod of the electric cylinder 15. Both ends of the corrugated airbag 21 are fixedly connected to the push-pull plate 22 and the cylinder shell 16. The push-pull plate 22 has a large contact area with the corrugated airbag 21, making the compression and stretching of the corrugated airbag 21 by the electric cylinder 15 more stable.

[0038] In this embodiment, as Figure 1 As shown, an anemometer 2 is installed on the upper surface of the discharge pipe 3, and the discharge speed of the oxygen-enriched air is observed through the anemometer 2.

[0039] In this embodiment, as Figure 4 As shown, the discharge pipe 3 is connected to a replenishment pipe 24, which is used to connect to an oxygen cylinder. When the oxygen demand is high, opening the valve 14 of the oxygen cylinder can temporarily increase the oxygen concentration.

[0040] In this embodiment, as Figure 4As shown, a fixing frame 25 is sleeved on the electric cylinder 15. The fixing frame 25 is connected to the housing 1 to achieve stable installation of the electric cylinder 15, making the compression and stretching of the corrugated airbag 21 by the electric cylinder 15 more stable.

[0041] Specifically, during use, the oxygen-enriched membrane oxygen generator 12 draws in air and discharges oxygen. The oxygen is sent into the discharge pipe 3, and the fan 11 accelerates the airflow into the discharge pipe 3. The oxygen mixes with the air to form oxygen-enriched air and accelerates the discharge of the oxygen-enriched air. The filter 10 filters the air. When there are many impurities attached to the filter 10, the support frame 9 is rotated to drive the filter 10 to rotate. This allows the part of the filter 10 with fewer impurities to be aligned with the fan 11 and the oxygen-enriched membrane oxygen generator 12, which can reduce the airflow resistance. At this time, the filter 10 can be cleaned without removing the filter 10 for cleaning and without interrupting the delivery of oxygen-enriched air.

[0042] When the cremator's demand for oxygen-enriched air decreases, the electric cylinder 15 slowly stretches the corrugated airbag 21 through the push-pull plate 22. The corrugated airbag 21 draws oxygen from the oxygen-enriched membrane oxygen generator 12 through the first delivery pipe 17. When the cremator's demand for oxygen-enriched air increases, the electric cylinder 15 compresses the corrugated airbag 21 through the push-pull plate 22, which can send the oxygen-enriched air in the corrugated airbag 21 into the discharge pipe 3.

[0043] When the inlet valve 14 of the cremator is closed, the air pressure in the discharge pipe 3 increases. At this time, valve 14 can be opened, and part of the oxygen-enriched air in the discharge pipe 3 flows from the circulation pipe 13 into the air inlet of the blower 11, so that this part of the oxygen-enriched air can be reused and the waste of oxygen-enriched air can be reduced.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
