Description

Technical Field

[0001] The utility model relates to the technical field of wood processing, in particular to a rubber wood modification tank. Background Art

[0002] Rubber wood modification refers to treating rubber wood by various methods to improve its performance, increase its added value or expand its application range. During the rubber wood modification process, it is necessary to put it into a modification tank and impregnate it with a modification liquid, and at the same time apply vacuum pressure to the rubber to make the modification liquid more fully penetrate into the pores and tiny spaces inside the rubber wood, thereby improving the uniformity and depth of impregnation.

[0003] Since it is necessary to pump out the air inside the modification tank through a vacuum pump before impregnation to make the modification tank in a vacuum state, the connection between the opening of the modification tank body and the door must be kept sealed. The door and the tank body of the traditional modification tank are only sealed by a rubber ring. The rubber ring will age after long-term use, resulting in a decline in the sealing effect and the problem of air leakage in the modification tank. If the modification tank leaks air during the impregnation of rubber wood, the impregnation effect will decline and the processing quality of rubber wood will be reduced. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rubber wood modification tank to solve the problem that the rubber ring ages after long-term use, resulting in a decline in the sealing effect and air leakage in the modification tank.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solution: a rubber wood modification tank

[0006] It includes a tank body, a vacuum pump is installed at the top of the tank body, one end of the tank body is hinged with a tank door, a sealing ring is fixedly connected to the outer wall of the tank door, and further includes:

[0007] An airbag for further sealing, both the sealing ring and the airbag are located between the connection of the tank body and the tank door, and a first one-way valve and a pressure relief valve are installed outside the airbag.

[0008] As a further description of the above-mentioned rubber wood modification tank: the air outlet of the vacuum pump is inclined, an installation ring is rotatably connected to the outside of the tank body, and blades are fixedly connected to the outer surface of the installation ring.

[0009] As a further description of the above-mentioned rubber wood modification tank: a plurality of trapezoidal grooves are opened on one side of the installation ring close to the tank door, and the spacing between adjacent trapezoidal grooves is the same.

[0010] As a further description of the above-mentioned rubber wood modification tank: an outer shell covering the outside of the installation ring is fixedly connected to the outside of the tank body, and an air inlet is opened at the top of the outer shell.

[0011] As a further description of a rubber wood modification tank of the above technology: An air delivery box is fixedly connected to the outside of the tank body. A piston is slidably connected inside the air delivery box. A movable rod is fixedly connected to one side of the piston. A spring is fixedly connected between the movable rod and the air delivery box. The movable rod penetrates through the outer shell and abuts against the mounting ring.

[0012] As a further description of a rubber wood modification tank of the above technology: A hose for delivering air is fixedly connected between the air delivery box and the first one-way valve.

[0013] In summary, due to adopting a rubber wood modification tank of the above technology, the beneficial effects of the present utility model are as follows:

[0014] 1. The airbag can expand and deform by injecting air and squeeze at the connection between the tank body and the tank door, tightly shielding the connection between the tank body and the tank door, thereby effectively improving the sealing performance at the connection between the tank body and the tank door, avoiding the entry of external air into the tank body due to the aging of the sealing ring, enabling the rubber wood inside the tank body to be fully impregnated, and ensuring the modification effect of the rubber wood.

[0015] 2. The air blown out by the vacuum pump during operation drives the blades and the mounting ring to rotate, and continuously delivers external air to the airbag through the movable rod, piston, second one-way valve and first one-way valve.

[0022] The following will clearly and completely describe the technology of a rubber wood modification tank in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0023] The present invention adopts the following technology of a rubber wood modification tank:

[0024] It includes a tank body 1, a vacuum pump 2 is installed on the top of the tank body 1, one end of the tank body 1 is hinged with a tank door 3, a sealing ring 4 is fixedly connected to the outer wall of the tank door 3, and further includes:

[0025] An airbag 5 for further sealing. Both the sealing ring 4 and the airbag 5 are located between the connection of the tank body 1 and the tank door 3. A first one-way valve 6 and a pressure relief valve 17 are installed outside the airbag 5. The airbag 5 inflates and expands to make its connection with the tank body 1 and the tank door 3 firm, thereby effectively improving the sealing performance at the connection of the tank body 1 and the tank door 3. The pressure relief valve 17 is used to balance the air pressure in the airbag 5, so that the air pressure in the airbag 5 always remains within a safe value range, avoiding the bursting and damage of the airbag 5 caused by excessive air pressure. The air in the airbag 5 cannot flow back into the hose 16 through the first one-way valve 6.

[0026] As a further description of the above-mentioned technology of a rubber wood modification tank: The air outlet of the vacuum pump 2 is inclined. The outer part of the tank body 1 is rotatably connected with a mounting ring 7, and blades 8 are fixedly connected to the outer surface of the mounting ring 7. When the vacuum pump 2 is started to pump out the air inside the tank body 1, the pumped air is ejected from the inclined air outlet of the vacuum pump 2 and enters through the air inlet at the top of the outer shell 10, and pushes the blades 8 to drive the mounting ring 7 to rotate.

[0027] As a further description of the above-mentioned technology of a rubber wood modification tank: A number of trapezoidal grooves 9 are provided on one side of the mounting ring 7 close to the tank door 3, and the spacing between adjacent trapezoidal grooves 9 is the same. During the rotation of the mounting ring 7, the movable rod 13 is pushed into the trapezoidal groove 9 by the compression elastic force of the spring 15. When the mounting ring 7 continues to rotate, the movable rod 13 can be extruded from the trapezoidal groove 9 through the inclined inner wall of the trapezoidal groove 9, so that the spring 15 is compressed again. The reciprocating movement of the movable rod 13 is realized in this way.

[0028] As a further description of a rubber wood modification tank of the above technology: An outer shell 10 covering the outside of the mounting ring 7 is fixedly connected to the outside of the tank body 1. An air inlet is provided at the top of the outer shell 10. The outer shell 10 is used to guide the air blown out by the vacuum pump 2 to improve the utilization rate of the air kinetic energy, and covers the outside of the mounting ring 7 and the blades 8 to prevent the rotation of the mounting ring 7 and the blades 8 from being affected by external factors.

[0029] As a further description of a rubber wood modification tank of the above technology: An air delivery box 11 is fixedly connected to the outside of the tank body 1. A piston 14 is slidably connected inside the air delivery box 11. A movable rod 13 is fixedly connected to one side of the piston 14. A spring 15 is fixedly connected between the movable rod 13 and the air delivery box 11. The movable rod 13 passes through the outer shell 10 and abuts against the mounting ring 7. The air in the air delivery box 11 cannot enter the outside through the second one-way valve 12. Therefore, when the piston 14 moves in the direction of the spring 15, the first one-way valve 6 is in the closed state at this time, and the air pressure inside the air delivery box 11 decreases, causing the outside air to enter the air delivery box 11 through the second one-way valve 12. When the piston 14 moves in the direction away from the spring 15, the second one-way valve 12 is in the closed state at this time, and the air in the air delivery box 11 opens the first one-way valve 6 through the hose 16 and enters the airbag 5.

[0030] As a further description of a rubber wood modification tank of the above technology: A hose 16 for delivering air is fixedly connected between the air delivery box 11 and the first one-way valve 6. The hose 16 can be deformed to facilitate the opening and closing of the tank door 3.

[0031] Working principle: After the rubber wood is placed inside the tank body 1, the vacuum pump 2 is started to pump out the air inside the tank body 1. The pumped air is ejected from the inclined air outlet of the vacuum pump 2 and enters through the air inlet at the top of the outer shell 10, and pushes the blades 8 to drive the mounting ring 7 to rotate. Since the spring 15 is in a compressed state and the movable rod 13 abuts against the mounting ring 7, during the rotation of the mounting ring 7, the movable rod 13 continuously makes reciprocating motions under the action of the elastic force of the spring 15 and the pushing of the inclined inner wall of the trapezoidal groove 9, driving the piston 14 to make reciprocating motions inside the air delivery box 11, so that the air is inhaled into the air delivery box 11 through the second one-way valve 12, and then is squeezed into the airbag 5 through the hose 16 and the first one-way valve 6. The airbag 5 is inflated to make the connection between itself and the tank body 1 and the tank door 3 firm, thereby effectively improving the sealing performance at the connection between the tank body 1 and the tank door 3. After the air pressure in the airbag 5 reaches the set value, the pressure relief valve 17 can discharge the excess air to prevent the airbag 5 from being damaged due to excessive air pressure.

[0032] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
