Description

Technical Field

[0001] The present invention relates to the field of air purification equipment, and particularly relates to a special disassembly and assembly tool for a hood-type oil fume purifier. Background Art

[0002] The hood-type oil fume purifier is used for purifying oil fume in the catering industry. It is installed above the cooking range. During the rising process of the flue gas, under the action of the fan in the hood-type oil fume purifier, the flue gas enters the interior of the hood-type oil fume purifier for purification, so that the flue gas reaches the emission standard. Among them, the main component for realizing the purification function of the hood-type oil fume purifier is the purification unit installed inside the casing. It purifies the flue gas through filtration, adsorption and other methods. After being used for a period of time, the interior of the purification unit will be contaminated with oil stains and soot, affecting the purification efficiency. Therefore, it needs to be cleaned frequently.

[0003] The casing of the existing hood-type oil fume purifier is fixed on the wall, and the purification unit is fixed inside the casing. When replacing or cleaning the purification unit, it is necessary to disassemble the whole hood-type oil fume purifier for replacement, or draw out the purification unit from the front of the casing for replacement. Since the purification unit is relatively heavy and needs to be moved down a certain height, it is quite troublesome.

[0004] When the purification unit of the hood-type oil fume purifier is set to be disassembled and assembled from below the hood-type oil fume purifier, due to the large gravity of the purification unit and the obstruction of the hood, it is very difficult for workers to support the purification unit with great force. Therefore, the purification unit cannot be held by the strength of the workers, resulting in the inability to disassemble and assemble the purification unit from below the hood-type oil fume purifier.

[0005] It can be seen that the existing technology still needs to be improved. Summary of the Invention

Detailed implementation method

[0041] The present invention provides a special disassembly and assembly tool for a hood-type oil fume purifier. To make the objectives, technical solutions, and effects of the present invention clearer and more definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the protection scope of the present invention.

[0042] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a hood-type oil fume purifier that facilitates the disassembly and assembly of a purification unit, including a purification box 1.1 and a hood 1.2 fixed to the bottom surface of the purification box 1.1. A purification unit 1.5 is provided inside the purification box 1.1, and a through hole 1.7 communicating with the hood 1.2 is provided below the purification unit 1.5 in the purification box 1.1. The purification unit 1.5 passes through the through hole 1.7 from bottom to top and is placed inside the purification box 1.1. A connecting member 1.6 is connected to the bottom surface of the purification box 1.1 and at the edge of the through hole 1.7. The purification unit 1.5 is fixed to the connecting member 1.6, and this edge refers to the position on the bottom surface of the purification box 1.1 close to the through hole 1.7.

[0043] Among them, the area of the top view of the purification unit 1.5 is placed inside the through hole 1.7, and one end of the connecting member 1.6 can be rotated into the through hole 1.7 to realize the fixed connection between the connecting member 1.6 and the purification unit 1.5; the connecting member 1.6 can also be rotated to a non-through hole 1.7 position, that is, when disassembling and assembling the purification unit 1.5, the connecting member 1.6 is rotated to the non-through hole 1.7 position, so that the purification unit 1.5 can be drawn out downward through the through hole 1.7.

[0044] In the above structure, when disassembling the purification unit 1.5, place the special disassembly and assembly tool with a lifting structure on the stove top or hang it on the bottom surface of the purification box 1.1, and then drive the lifting structure to rise so that the lifting structure supports the bottom surface of the purification unit 1.5. Then rotate the connecting member 1.6 to move the connecting member 1.6 away from the through hole 1.7 position, and then drive the lifting structure to descend, and the purification unit 1.5 is drawn out from below the hood 1.2 machine to complete the disassembly of the purification unit 1.5. The steps for installing the purification unit 1.5 are opposite, that is, first place the special disassembly and assembly tool with a lifting structure on the stove top or hang it on the bottom surface of the purification box 1.1 and make the lifting structure in the lowest state, and then place the purification unit 1.5 on the lifting structure. Then drive the lifting structure to rise so that the purification unit 1.5 is inserted into the purification box 1.1 through the through hole 1.7, and then rotate the connecting member 1.6 to place the purification unit 1.5 on the connecting member 1.6 to complete the installation of the purification unit 1.5.

[0045] When disassembling and assembling the purification unit 1.5, since a special tool is used to disassemble it from below the hood 1.2 machine, it is not necessary to manually move the relatively heavy purification unit 1.5 at a high position. Only the lifting and rotation of the lifting structure of the special tool and the rotation of the connecting member 1.6 need to be manually controlled, which greatly reduces the labor intensity of workers and makes it more convenient and efficient when cleaning or replacing and maintaining the hood 1.2 machine.

[0046] In the above, when disassembling and assembling the purification unit 1.5, the special disassembly and assembly tool passes through the inside of the hood 1.2. Therefore, structures such as the water separation plate and the oil-water separator installed inside the hood 1.2 are all installed in a detachable manner, so that before disassembling and assembling the purification unit 1.5, the structures inside the hood 1.2 are removed so as not to affect the disassembly and assembly of the purification unit 1.5. Among them, a fan for driving air flow is also detachably connected inside the hood 1.2 or inside the purification box 1.1.

[0047] Among them, the purification unit 1.5 can be a filter net, such as an activated carbon filter net, etc., or an electrostatic field.

[0048] Refer to Figure 5 and Figure 6 , the connecting member 1.6 includes a connecting piece 1.61. One end of the connecting piece 1.61 is rotatably connected to the bottom surface of the purification box 1.1, and the other end abuts against the bottom surface of the purification unit 1.5. In practical applications, the purification unit 1.5 can be connected to the connecting piece 1.61 by screws to improve the firmness of its connection position.

[0049] In a preferred embodiment, the connecting member 1.6 further includes a ball screw placed on one side of the connecting piece 1.61. The ball screw includes a mounting sleeve 1.66 vertically fixed to the bottom surface of the purification box 1.1, a spring 1.64 placed inside the mounting sleeve 1.66, and a ball 1.62, and the ball 1.62 is placed below the spring 1.64. A notch 1.63 is provided on the connecting piece 1.61 corresponding to the position of the ball 1.62. When the connecting piece 1.61 is in the position abutting against the purification unit 1.5, the ball 1.62 is stuck in the notch 1.63. Among them, one end of the ball 1.62 passes through the mounting sleeve 1.66, and the notch 1.63 cooperating with the ball 1.62 is provided, so that after the ball 1.62 is placed in the notch 1.63, if there is no force in the rotation direction of the connecting piece 1.61, the position of the connecting piece 1.61 is stuck by the ball 1.62 and thus fixed. When the worker rotates the connecting piece 1.61 by an external force, the spring 1.64 contracts, so that the ball 1.62 can be removed from the notch 1.63. Therefore, in use, after installing the purification unit 1.5, it is only necessary to manually rotate the connecting piece 1.61 and make one end of the connecting piece 1.61 placed below the purification unit 1.5, without additional fixation. Among them, the notch 1.63 can be a concave pit, a through hole or a blind hole.

[0050] In a further preferred embodiment, an adjusting screw 1.65 is provided at one end of the mounting sleeve 1.66 away from the ball 1.62. By turning the adjusting screw 1.65, the tightness of the spring 1.64 is adjusted so that the ball 1.62 has sufficient force to prevent the connecting piece 1.61 from rotating.

[0051] In practical applications, in order to facilitate the turning of the connecting piece 1.61, a handle 1.67 can be fixed to the bottom surface of the connecting piece 1.61.

[0052] In a preferred embodiment, the purification unit 1.5 is an electrostatic field. A thimble 2 connected to the cathode frame 1.53 of the electrostatic field is provided at the upper end of the purification box 1.1 corresponding to the through hole 1.7. An electric control box 1.4 is fixed to the front of the purification box 1.1. The thimble 2 passes through the purification box 1.1 and is connected to the power supply in the electric control box 1.4. After the electrostatic field is installed, the thimble 2 abuts against the cathode frame 1.53, so that the cathode frame 1.53 is electrically connected to the power supply in the electric control box 1.4.

[0053] Refer to Figure 8 , in a preferred embodiment, the electrostatic field is horizontally arranged, and a baffle 1.10 is fixed below the electrostatic field. The baffle 1.10 is connected to the connecting piece 1.6 and abuts against the bottom surface of the purification box 1.1. That is, after the electrostatic field is installed, the baffle 1.10 seals the through hole 1.7 to prevent the flue gas from passing through there. In this embodiment, the electrostatic field can be a honeycomb electric field or a plate electric field. The electrostatic field is placed in the middle of the purification box 1.1, and an air inlet 1.11 communicating with the smoke hood 1.2 is provided at one end of the purification box 1.1, and an air outlet 1.3 is provided at the other end, so that the flue gas enters the inside of the purification box 1.1 from one end of the purification box 1.1 and is discharged from the other end through the purification electric field, realizing the purification of the flue gas.

[0054] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7, in a preferred embodiment, the electrostatic field is a honeycomb field, and the honeycomb field is vertically arranged. That is, the honeycomb field includes an anode cylinder 1.52, anode substrates 1.51 connected to both ends of the anode cylinder 1.52, a cathode frame 1.53 fixed to the anode substrates 1.51 through insulators, cathode needles (not shown in the figure) fixed to the cathode frame 1.53 and inserted into the center of the anode cylinder 1.52 at one end, and side plates 1.54 connected to both ends of the anode substrates 1.51. There is a sealing plate 1.12 inside the electric control box. The side of the honeycomb field abuts against the sealing plate 1.12. After the honeycomb field is installed, the side plate of the honeycomb field is attached to the sealing plate 1.12. That is, the anode substrate 1.51 at the lower end of the honeycomb field is connected to the connector 1.6, and the edge of the anode substrate 1.51 connected to the connector 1.6 abuts against the bottom surface of the electric control box 1.4. The top surface of the purification box 1.1 is provided with an air outlet 1.3, and the lower end of the honeycomb field is directly communicated with the smoke hood 1.2.

[0055] Preferably, the upper end of the sealing plate 1.12 is provided with a folded edge, and the top surface of the anode substrate 1.51 at the upper end of the honeycomb field abuts against the folded edge of the sealing plate 1.12 to achieve the sealing between the honeycomb field and the sealing plate, so that all the gases to be purified pass through the inside of the honeycomb field.

[0056] In a preferred embodiment, there are two electrostatic fields, and two through holes 1.7 are correspondingly arranged on the bottom surface of the purification box 1.1.

[0057] In a preferred embodiment, a sealing ring is provided on the folded edge at the upper end of the sealing plate 1.10. The sealing ring can be made of rubber or silica gel material to ensure the sealed connection between the sealing plate and the honeycomb field. Since the sealing ring has a certain shrinkage ability, when disassembling and assembling with special tools, the purification unit 1.5 can be lifted by a small height using the lifting structure to facilitate the rotation of the connecting piece 1.61.

[0058] The bottom surface of the purification box 1.1 is provided with a lifting ring 1.9 for hoisting special tools. The lifting ring 1.9 can also be fixed on one side of the through hole 1.7, and a long strip-shaped buckle groove 1.8 is provided on the side opposite to the lifting ring 1.9. When in use, the special tool is connected to the lifting ring 1.9 and the long strip-shaped buckle groove 1.8. Preferably, the bracket of the purification box 1.1 is made of square tubes, and the long strip-shaped buckle groove 1.8 is provided on the square tubes. Therefore, after the long strip-shaped buckle groove 1.8 is provided, the long strip-shaped buckle groove 1.8 will not communicate with the inside of the purification box 1.1 either.

[0059] Refer to Figure 12 and Figure 16, Among the above, the ejector pin 2 includes a base 2.1, an elastic element 2.2, and an ejector pin cap 2.3. The base 2.1, the elastic element 2.2, and the ejector pin cap 2.3 are all made of conductive materials. One end of the elastic element 2.2 is fixedly connected to an end face of the base 2.1, and the other end of the elastic element 2.2 is fixedly connected to the ejector pin cap 2.3. And the elastic element 2.2 can be bent when stressed, and the elastic element 2.2 can reset after the external force disappears, that is, return to the straight state. Specifically, the base 2.1 is used to connect to the power supply of the air purification and is fixed to the insulator. The insulator is used to fix the power supply to prevent the power supply from contacting the outer shell of the air purifier. The ejector pin cap 2.3 is used to abut against the cathode frame, and the elastic element 2.2 is used to connect the base 2.1 and the ejector pin cap 2.3. Therefore, the electrical connection between the power supply and the cathode frame is realized.

[0060] In practical applications, the elastic element 2.2 can also be rotatably connected to the base 2.1 and the elastic element 2.2 can also be rotatably connected to the ejector pin cap 2.3.

[0061] When the above-mentioned ejector pin 2 used horizontally is in use, the cathode frame abuts against the side of the ejector pin cap 2.3, and the bendability of the elastic element 2.2 can eliminate the distance error between the positions of the cathode frame and the power supply. And under the action of the restoring force of the elastic element 2.2, the ejector pin cap 2.3 and the cathode frame are in better contact.

[0062] In a preferred embodiment, the elastic element 2.2 is a spring.

[0063] In a preferred embodiment, the base 2.1 is in a sleeve shape, and the base 2.1 and the spring, and the ejector pin cap 2.3 and the spring are both fixedly connected by screws 2.4. Among them, setting the base 2.1 in a sleeve shape facilitates the installation of the screw 2.4 for connecting the base 2.1 and the spring, that is, the nut end of the screw 2.4 can be placed inside the base 2.1, and the screw end of the screw 2.4 extends outside the base 2.1 and is threadedly connected to the spring, realizing the connection of the screw 2.4 between the base 2.1 and the spring. A central through hole is provided in the center of the ejector pin cap 2.3, and the screw 2.4 passes through the central through hole and is connected to the spring.

[0064] Refer to Figure 13 , In a preferred embodiment, the outer diameter of the screw 2.4 is matched with the inner diameter of the spring, that is, the thread of the screw 2.4 is matched with the inner wall of the spring. Since the inner wall of the spring is also threaded, the screw 2.4 and the spring are fixedly connected through the threaded connection between the inner wall of the spring and the thread of the screw 2.4, without the need for additional connecting parts, and the connection is convenient.

[0065] Refer to Figure 14, in a preferred embodiment, internal thread sleeves 2.5 are fixed to both ends of the spring, and screws 2.4 are fixed to the internal thread sleeves 2.5. In this embodiment, the internal thread sleeves 2.5 are welded inside the spring, and the screws 2.4 are threadedly connected to the internal thread sleeves 2.5 to achieve the fixed connection between the spring and the screws 2.4.

[0066] In a preferred embodiment, the pitch in the middle of the spring is greater than the diameter of the spring wire, so that the spring has a certain compression capacity, and the thimble can also be installed like the existing thimble. That is, after installation, the spring shrinks under the axial pressure to eliminate the distance error between the cathode holder and the power supply position.

[0067] In the above structure, the elastic element 2.2 can also be an elastic steel sheet. The elastic steel sheet means that the steel sheet has a certain bending ability. When subjected to pressure, the steel sheet bends to eliminate the distance error between the cathode holder and the power supply position, and the steel sheet can return to the straight state after the pressure is eliminated.

[0068] Refer to Figure 15 , in an embodiment, the thimble cap 2.3 is circular, and a number of small teeth are evenly distributed on its edge.

[0069] Refer to Figure 16 , in an embodiment, in order for the thimble cap 2.3 to better contact the cathode holder, the thimble cap 2.3 can be set to a conical shape, and a number of small teeth are evenly distributed on its edge.

[0070] Refer to Figure 9 and Figure 10 , a special disassembly and assembly tool for a hood-type oil fume purifier, including a bracket 3.1 and a lifting structure 3.5 fixed in the middle of the bracket 3.1. The bracket 3.1 is provided with frames 3.2 on both sides of the lifting structure 3.5. One side of the upper end of the frame 3.2 is provided with a first connecting member, and the other side of the upper end of the frame 3.2, away from the bolt 3.4, is provided with a second connecting member. The first connecting member and the second connecting member can be fixed to the bottom surface of the purification box 1.1 by snap connection or screw connection.

[0071] Specifically, the first connecting member is preferably a horizontally arranged bolt 3.4, and the second connecting member is preferably a vertically arranged quick lock 3.3. Among them, the lifting structure 3.5 is used to support the purification unit 1.5 of the hood-type oil fume purifier, and the bolt 3.4 and the quick lock 3.3 are used to install the special disassembly and assembly tool on the hood-type oil fume purifier. When in use, the bolt 3.4 is buckled on the lifting ring 1.9 on the bottom surface of the purification box 1.1, and the quick lock 3.3 is buckled with the long strip-shaped buckle groove 1.8 on the bottom surface of the purification box 1.1 to realize the quick installation of the special disassembly and assembly tool on the bottom surface of the hood-type oil fume purifier and achieve positioning.

[0072] In practical applications, for the convenience of inserting the bolt 3.4 onto the lifting ring 1.9, the end of the bolt 3.4 away from the frame 3.2 is provided with a conical surface.

[0073] Refer to Figure 11 , wherein, the quick locking member 3.3 includes a connecting rod 3.34, a first connecting seat 3.37 and a second connecting seat 3.32. The first connecting seat 3.37 and the second connecting seat 3.32 are fixed on the side surface of the frame 3.2. The second connecting seat 3.32 is placed above the first connecting seat 3.37. The connecting rod 3.34 is vertically arranged and slidably connected to the first connecting seat 3.37 and the second connecting seat 3.32. The connecting rod 3.34 is provided with a first limiting member 3.38 below the first connecting seat 3.37, and the connecting rod 3.34 is provided with a second limiting member 3.31 above the second connecting seat 3.32; the distance between the first limiting member 3.38 and the second limiting member 3.31 is greater than the distance between the first connecting seat 3.37 and the second connecting seat 3.32.

[0074] In the above structure, during use, first buckle the bolt 3.4 onto the lifting ring 1.9 on the bottom surface of the purification box 1.1, and then push the connecting rod 3.34 upward, and make the second limiting member 3.31 pass through the long strip-shaped buckle groove 1.8, and then rotate the connecting rod 3.34 so that the second limiting member 3.31 is stuck on the long strip-shaped buckle groove 1.8, and the first limiting member 3.38 abuts against the lower part of the first connecting seat 3.37, thus realizing the fixation of the special disassembly and assembly tool. Then, drive the lifting structure 3.5 to support the purification unit 1.5 and realize the disassembly and assembly work of the purification unit 1.5.

[0075] In the above, the positions of the second limiting member 3.31 and the long strip-shaped buckle groove 1.8 are cooperatively arranged. Therefore, when the bolt 3.4 is buckled onto the lifting ring 1.9 on the bottom surface of the purification box 1.1 and the second limiting member 3.31 is stuck on the long strip-shaped buckle groove 1.8, the fixation of the special disassembly and assembly tool is realized, and at the same time, the positioning of the special disassembly and assembly tool relative to the hood type oil fume purifier is realized.
