Description

Technical Field

[0001] This utility model belongs to the technical field of oxygen generation equipment, and in particular relates to a VPSA oxygen generation device with a high-efficiency gas separation chamber design. Background Technology

[0002] VPSA (Vibration-Vacuum Absorption Spectroscopy) oxygen production is a highly efficient gas separation technology that utilizes the selective adsorption properties of adsorbents for oxygen and nitrogen in the air to extract oxygen at room temperature. This process uses a system composed of multiple adsorption towers that alternately cycle adsorption and vacuum desorption to continuously produce high-purity oxygen. Compared to traditional processes, VPSA oxygen production offers advantages such as low energy consumption, ease of operation, and rapid start-up, and is widely used in industrial production and medical oxygen supply.

[0003] VPSA adsorbs substances other than oxygen from the air through molecular sieves. However, the molecular sieves are easily affected by external factors such as gravity inside the equipment, which can lead to localized accumulation. This reduces the contact area between the molecular sieves and the gases in the air, and decreases the chance of contact with impurities such as nitrogen, thus affecting the oxygen production efficiency of the equipment. To address this, we propose a VPSA oxygen production equipment with a highly efficient gas separation chamber design. Utility Model Content

[0004] The purpose of this invention is to provide a VPSA oxygen generator with a highly efficient gas separation chamber design. By setting up a mixing structure, specifically by starting a motor to drive a gear ring to rotate, the rotating gear ring, through a connecting rod, drives a positioning plate and a transmission shaft to rotate. This causes several blades to move in a circular motion along the transmission shaft. This circular motion of the blades pushes the molecular sieve to flow within the conical outer casing, preventing localized accumulation of the molecular sieve and avoiding a reduction in the contact area between the molecular sieve and the air. This ensures the molecular sieve has sufficient contact with impurities such as nitrogen, thereby guaranteeing the oxygen generation efficiency of the equipment. This invention solves the problem in existing VPSA systems where the molecular sieve adsorbs substances other than oxygen from the air, and the molecular sieve is easily affected by external factors such as gravity inside the equipment, leading to localized accumulation, reduced contact area with the air, and decreased contact with impurities such as nitrogen, thus affecting the oxygen generation efficiency of the equipment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a VPSA oxygen generator with a high-efficiency gas separation chamber design, including a mixing structure. The mixing structure is used to keep the molecular sieve inside the device in a flowing state. The mixing structure includes a conical outer box, and a drive shaft is arranged at the center of the conical outer box. Positioning plates are installed at the top and bottom of the drive shaft, and three mixing shafts are arranged between the two positioning plates.

The coupling at the bottom output end of the motor is mounted on the outer wall of the top of the gear. Several arc-shaped grooves are formed at the bottom of the collection box. These arc-shaped grooves are arranged in a circular array around the bottom of the collection box. By setting the arc-shaped grooves at the bottom of the collection box, oxygen from the conical outer box can be poured into the collection box.

[0016] The outer radius of the topmost part of the drive shaft is larger than the inner radius of the part through which the disk is penetrated, and the disk is able to support the top of the drive shaft.

[0017] Furthermore, the mixing assembly includes a vacuum pump mounted on the right outer wall of the top of the conical outer box, and a collection box is provided at the center of one of the two conical conduits close to each other, with the interior of the conical conduits connected to the collection box via connecting pipes;

Several flow guide grooves are opened on the annular protrusions at the top of the inner wall of the conical outer box. The flow guide grooves are arranged in a circumferential array with the conical outer box as the center. By setting a vacuum pump, the pressure inside the conical outer box can be adjusted. After adsorption is completed, a vacuum state is formed by the vacuum pump to discharge the impurities adsorbed by the molecular sieve.

[0019] The collection box is equipped with a valve inside the connecting pipe, and a connector is installed at the center of the bottom of the collection box. The conical conduit is designed to be conical with a narrow top and a wide bottom.

Several pads are installed on the top of the support base frame, and the tops of the pads are all installed on the outer wall of the bottom of the conical outer box. By setting the support base frame in a trapezoidal shape, the contact surface between the bottom of the support base frame and the ground can be increased, thereby improving the stability of the support base frame.

[0024] The bottom center of the outer shell back plate and the bottom of the back of the outer shell back plate are penetrated by a pin, and the rectangular outer shell and the outer shell back plate are rotatably connected to each other by the pin.

[0025] This utility model has the following beneficial effects:

[0026] This invention employs a hybrid structure, specifically by starting a motor to drive a gear ring to rotate. The rotating gear ring, through a connecting rod, drives a positioning plate and a transmission shaft to rotate, causing several blades to move in a circular motion along the transmission shaft. This circular motion of the blades propels the molecular sieve to flow within the conical outer casing, preventing localized accumulation of the molecular sieve and avoiding a reduction in the contact area between the molecular sieve and gases in the air. This ensures that the molecular sieve has the opportunity to contact impurities such as nitrogen, thereby guaranteeing the oxygen production efficiency of the equipment.

[0027] This invention employs a positioning mechanism. Specifically, the gas cylinder is inserted into the clamp on the front of the outer shell back plate. Then, the outer shell back plate is rotated forward to move the gas cylinder into the interior of the rectangular shell. Next, a knob is rotated to move the two circular protrusions connected by the thread on the double-ended lead screw away from each other, and finally insert the circular protrusions into the circular holes on the side of the rectangular shell. This allows the gas cylinder to be quickly positioned at the center of the rectangular shell, facilitating cylinder replacement by the operator. Once the gas cylinder is full, rotating the knob unlocks the device and allows the gas cylinder to be removed, ensuring continuous production of the oxygen generator.

[0043] Support frame assembly 22 is disposed below the mixing component 11 and the positioning component 21. The support frame assembly 22 is used to support the top-mounted component. The support frame assembly 22 is trapezoidal in shape, and the outer walls of the left and right sides of the support frame assembly 22 are inclined surfaces.

[0044] The mixing assembly 11 includes two conical outer boxes 1111, both on the same horizontal line and arranged side by side. A conical guide tube 1112 is installed at the top center of each of the two outer boxes 1111. A disc 112 is installed at the top center of the inner wall of each outer box 1111. A drive shaft 113, a positioning plate 114, and a mixing shaft 115 are all located at the center inside the conical outer boxes 1111.

The coupling at the bottom output end of motor 1182 is mounted on the outer wall of the top of gear 1172.

The rotating shaft 113 causes several blades 116 to move in a circular motion along the drive shaft 113. Through the circular motion of the blades 116, the blades 116 push the molecular sieve to flow inside the conical outer box 1111, preventing local accumulation of the molecular sieve and avoiding a reduction in the contact area between the molecular sieve and the gas in the air due to accumulation. This ensures that the molecular sieve has the opportunity to contact impurities such as nitrogen, thereby ensuring the oxygen production efficiency of the equipment. The outer radius of the top of the drive shaft 113 is larger than the inner radius of the part through which the disk 112 is penetrated, and the disk 112 can support the top of the drive shaft 113.

[0045] The mixing assembly 11 includes a vacuum pump 1183, which is mounted on the right outer wall of the top of the conical outer box 1111. A collection box 119 is provided at the center of two conical tubes 1112 close to each other on one side.

[0047] The positioning assembly 21 includes a lead screw housing 216, which is mounted at the top center of the outer wall of the back of the housing back plate 212.

Slide plates 213 are threadedly connected to the left and right sides of the outer wall of the bidirectional lead screw 217. Square holes are opened on the left and right sides of the top of the housing back plate 212. The outer wall of the slide plate 213 is slidably connected to the inner wall of the square hole of the housing back plate 212. Circular protrusions 214 are installed at the center of the two slide plates 213 on opposite sides. Springs 215 are sleeved on the outer side of the outer wall of the circular protrusions 214. The inner wall of the square hole of the housing back plate 212 is flexibly connected to the slide plate 213 through the springs 215. Circular protrusions 214 are opened on the sides of the rectangular housing 211 and the housing back plate 212. The outer diameter of the circular protrusion 214 is adapted to the inner diameter of the circular hole and inserted. The gas cylinder is inserted into the clamp on the front of the back plate 212 of the outer shell, and then the back plate 212 of the outer shell is rotated forward to move the gas cylinder into the interior of the rectangular outer shell 211. Then, the knob 218 is rotated to make the two circular protrusions 214 connected to the thread on the double-acting screw 217 move away from each other, and finally insert the circular protrusions 214 into the circular holes on the side of the rectangular outer shell 211. This can quickly position the gas cylinder in the center of the rectangular outer shell 211, making it convenient for the staff to replace the gas cylinder. When the gas cylinder is full, the knob 218 can be rotated to unlock the equipment and remove the gas cylinder, ensuring that the oxygen generating equipment can carry out continuous production. The threads on the left side of the outer wall of the double-acting screw 217 are opened in opposite directions to the threads on the right side of the outer wall of the double-acting screw 217.

[0048] Several clamps are installed on the front of the back panel 212 of the outer shell, and the clamps are arranged in a vertical array with the front of the back panel 212 of the outer shell as the center.

[0049] The support frame assembly 22 includes a support base 221, which is located at the bottom of the conical outer box 1111.

[0050] A specific application of this embodiment is as follows: In use, the molecular sieve is first placed into the conical outer box 1111 through the feed port at the top of the conical outer box 1111. Then, the motor 1182 is started, and the output end of the motor 1182 drives the gear 1172 to rotate. Then, the gear 1172 is driven to rotate through the meshing connection with the gear ring 1171. In turn, the connecting rod 1173 drives the positioning plate 114 to rotate, and the positioning plate 114 drives the transmission shaft 113 installed at the center to rotate. The four mixing shafts 115 set on the outside of the transmission shaft 113 drive the several blades 116 installed on the outer surface to rotate, so that the blades 116 push the molecular sieve to flow, preventing the molecular sieve from accumulating locally and affecting the working performance of the equipment.

[0051] Next, air is injected into the interior of the conical outer box 1111 through the air inlet on the bottom side of the conical outer box 1111. The air floats upward from the bottom of the conical outer box 1111. As the air floats upward, it passes through one molecular sieve particle after another. These molecular sieves adsorb nitrogen and other impurities in the air. The molecular sieves have a weak adsorption force on oxygen, allowing oxygen to pass through many molecular sieve particles and move to the top of the conical outer box 1111. Then, it flows into the conical conduit 1112 through several slots at the top of the conical outer box 1111, and finally enters the collection box 119 from the connecting pipe of the conical conduit 1112.

[0052] Next, close the valve inside the connecting pipe connected to the collection box 119, and then start the vacuum pump 1183 to create a vacuum state inside the conical outer box 1111, allowing the molecular sieve to release nitrogen and other impurities. These impurities will flow down the slope of the conical outer box 1111 into the bent pipe installed on the front bottom of the conical outer box 1111 and finally be discharged outward.

[0053] Next, insert the gas cylinder between the clamps on the front of the outer shell back plate 212, then rotate the top of the outer shell back plate 212 to the front to move the gas cylinder inside the rectangular outer shell 211. Then rotate the knob 218 to make the double-acting screw 217 connect with the slide plate 213 through the thread, so that the two slide plates 213 move away from each other. While stretching the spring 215, insert the circular protrusion 214 into the circular hole on the side of the rectangular outer shell 211 and the outer shell back plate 212 to lock the rectangular outer shell 211 and the outer shell back plate 212.

[0054] Finally, connect the top of the gas cylinder to the connector at the bottom of the collection box 119, and then inject the oxygen collected in the collection box 119 into the gas cylinder. When the gas cylinder is full, remove the oxygen-filled gas cylinder and replace it with an air-filled gas cylinder.
