Description

Technical Field

[0001] This utility model relates to the field of perfume processing technology, and in particular to a multi-stage filtration device for perfume production. Background Technology

[0002] As a high-value-added daily chemical product, perfume production requires extremely strict standards for purity. Filtration is a crucial step in the perfume production process to remove impurities and ensure the product's clarity. The sealing performance of the filtration device used in this step is paramount; it must prevent the loss of volatile components such as alcohol and also prevent external contaminants from entering the container.

[0003] To ensure a reliable seal, existing filtration devices typically use flanges and multiple bolts to fasten the tank and lid, or multiple independent clips around the tank opening for locking. While these traditional locking methods can provide sufficient sealing pressure, they have revealed significant shortcomings in actual production operations.

[0004] Specifically, with bolt fastening, operators must loosen all bolts one by one with a wrench or other tools each time the lid needs to be opened for inspection, cleaning, or filter replacement. The bolts must then be tightened again to close the lid, making the entire process tedious, time-consuming, and labor-intensive. While a multi-clip design eliminates the need for tools, operators still need to manually open and close each clip individually. This is equally inconvenient and inefficient when the tank is large.

[0005] This inefficient method of opening and closing the lid significantly prolongs equipment downtime and maintenance time in perfume production processes that require frequent equipment cleaning to prevent cross-contamination between batches, becoming a bottleneck affecting overall production efficiency.

[0006] Therefore, this utility model proposes a multi-stage filtration device for perfume production to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems in the existing technology of multi-stage filtration devices for perfume production, the lid locking structure usually adopts multiple bolts or multiple independent buckles, which makes the opening and closing process cumbersome, time-consuming and inefficient. The present invention aims to provide a multi-stage filtration device for perfume production with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a multi-stage filtration device for perfume production, including a tank, several legs fixedly connected to the bottom of the tank, a lid that can be opened and closed on the top of the tank, and a feed pipe fixedly connected to the lower part of the side wall of the tank via a connecting block; the device also includes a locking mechanism.

[0009] The locking mechanism includes an outer fixing block fixed to the outer wall of the tank; a slide rod slidably connected to the outer fixing block; a locking plate fixedly connected to the end of the slide rod away from the tank; a connecting plate fixedly connected to the slide rod at one end; a crossbar fixedly connected to the other end of the connecting plate and operably extending out of the outer fixing block; and a spring sleeved on the slide rod and with its two ends abutting against the outer fixing block and the locking plate respectively.

[0010] Preferably, a locking hook is fixedly connected to the bottom of the bucket lid, and the bottom of the locking hook has a downwardly inclined guide surface for pushing the locking plate to move when the bucket lid is closed, and engaging and fixing it after passing the locking plate.

[0011] Preferably, the interior of the tank may also be detachably provided with a filter assembly and a disassembly mechanism for fixing the filter assembly.

[0012] Preferably, the filter assembly includes a connecting column, on which a coarse filter, a medium filter, and a fine filter are fixedly connected in sequence along its axial direction.

[0013] Preferably, the inner wall of the tank is fixed with retaining ring 1, retaining ring 2 and retaining ring 3 at intervals along the vertical direction; the inner diameters of retaining ring 1, retaining ring 2 and retaining ring 3 decrease sequentially, and are used to support the coarse filter, the medium filter and the fine filter respectively.

[0014] Preferably, the disassembly mechanism includes a storage ring fixed to the inner wall of the tank, a connecting shaft rotatably connected to the storage ring, and an arc-shaped rod fixedly connected to one end of the connecting shaft; the arc-shaped rod selectively engages or disengages from the filter assembly by rotating the connecting shaft.

[0015] Preferably, a limiting bead for limiting the position is also slidably sleeved on the arc-shaped rod.

[0017] 1. This utility model solves the problems of existing filter devices that require layer-by-layer disassembly and assembly, cumbersome process, time-consuming and labor-intensive process, and inconvenient cleaning by setting up a filter component that can be picked up and put down as a whole, using multi-stage retaining rings on the inner wall of the tank for quick positioning, and then using a swingable arc rod for quick locking and releasing. It achieves the beneficial effects of simplifying operation, realizing quick installation and disassembly of filter components, thereby greatly shortening the cleaning and maintenance time of the equipment and improving production efficiency.

[0018] 2. This utility model solves the problem of complex and inefficient opening and closing operations caused by bolts or multiple buckles locking the tank top cover in the prior art, by setting a locking hook on the lid and a locking plate driven by a spring to reset on the tank body. It achieves the convenient operation of "one press to lock and one pull to open", which significantly improves the convenience of operation and work efficiency during equipment maintenance and internal cleaning.

[0019] 3. This utility model integrates the quick-release structure of the filter component with the quick-lock structure of the lid, solving the problems of disjointed operation process and long maintenance cycle caused by the complex structure of traditional filtration equipment.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 5 This utility model provides a multi-stage filtration device for perfume production, which aims to solve the problems of complex disassembly and assembly of filter components and cumbersome operation and low efficiency of existing perfume production filtration devices.

[0030] like Figure 1 As shown, the multi-stage filtration device for perfume production includes a tank 1. Several support legs 2 for stable support are fixedly connected to the bottom of the tank 1 by welding. A feed pipe 3 is fixedly connected to the lower side wall of the tank 1 by a connecting block 4. A lid 5 is provided on the top of the tank 1 for sealing the opening of the tank 1. The core structure of the device is a locking mechanism 8 for locking the lid 5 to the tank 1, and a filter assembly 78 set inside the tank 1 and a disassembly mechanism 7 for fixing or releasing it.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, the locking mechanism 8 includes an outer fixing block 81, which is fixed to the outer wall of the tank 1 by bolts or welding. A through groove is provided inside the outer fixing block 81, and a sliding rod 85 is slidably connected to the through groove. A locking plate 84 is fixedly connected to one end of the sliding rod 85 away from the tank 1, and a connecting plate 82 is fixedly connected to one end of the other end of the sliding rod 85. A crossbar 83 is fixedly connected to the other end of the connecting plate 82, and the crossbar 83 can be operably extended out of the outer fixing block 81 for easy manual pulling. A spring 86 is sleeved on... Around the outer periphery of the slide bar 85, the two ends of the spring 86 abut forward against the back side of the locking plate 84 and backward against the inner wall of the outer fixing block 81, respectively. In cooperation with the locking mechanism 8, a locking hook 6 is fixedly connected at the corresponding position at the bottom of the bucket lid 5. The bottom of the locking hook 6 has a downward inclined guide surface. When the bucket lid 5 is closed downward, the guide surface of the locking hook 6 contacts and pushes the locking plate 84 to move against the elastic force of the spring 86. When the locking hook 6 completely passes the locking plate 84, the locking plate 84 automatically resets under the elastic force of the spring 86, thereby locking and locking the locking hook 6.

[0032] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment is that the multi-stage filtration device for perfume production also includes a filter component 78 that is detachably disposed inside the canister 1. Furthermore, the filter component 78 can be quickly installed, positioned, and disassembled through the disassembly mechanism 7 and multiple retaining rings disposed on the inner wall of the canister 1.

[0033] Please refer to the following carefully. Figure 1 , Figure 3 , Figure 4 and Figure 5 The core structure will be described in detail below:

[0034] The filter assembly 78 includes a vertically arranged connecting column 784. A coarse filter 781, a medium filter 782, and a fine filter 783 are fixedly connected to the connecting column 784 from top to bottom along its axial direction by welding or threaded connection, forming an integral multi-stage filtration unit. To position and support the filter assembly 78, a first retaining ring 75, a second retaining ring 76, and a third retaining ring 77 are fixed at intervals along the vertical direction on the inner wall of the tank 1. The inner diameters of the first retaining ring 75, the second retaining ring 76, and the third retaining ring 77 decrease sequentially, and are used to support the outer peripheral edges of the coarse filter 781, the medium filter 782, and the fine filter 783, respectively. This stepped support structure ensures that the filter assembly 78 can be automatically aligned and stably placed when it is put into the tank 1.

[0035] To lock and unlock the positioned filter assembly 78, a disassembly mechanism 7 is fixed to the inner wall of the tank 1. The disassembly mechanism 7 includes a storage ring 71 fixed to the inner wall of the tank 1. A connecting shaft 72 is rotatably connected to the storage ring 71 via a pin. An arc-shaped rod 73 is fixedly connected to one end of the connecting shaft 72. A limiting bead 74 for auxiliary limiting is slidably sleeved on the body of the arc-shaped rod 73. During installation, after the filter assembly 78 is placed on the three retaining rings, the arc-shaped rod 73 is swung by rotating the connecting shaft 72, causing the end of the arc-shaped rod 73 to engage with the top structure of the filter assembly 78, thereby locking it securely. Conversely, rotating the arc-shaped rod 73 in the opposite direction disengages it from the engaging state, allowing the connecting column 784 to be lifted and the entire filter assembly 78 to be removed. This combination structure, which uses retaining rings for positioning and arc-shaped rod 73 for locking, ensures quick assembly and disassembly of the entire filter device, greatly facilitating cleaning and maintenance.

[0036] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0037] In a preferred embodiment, in order to achieve quick self-locking of the lid 5, a locking hook 6 is fixedly connected to the bottom of the lid 5. The bottom of the locking hook 6 is specifically a hook-shaped structure with a downwardly inclined guide surface. This guide surface is used to smoothly push the locking plate 84 when the lid 5 is pressed down to close, so that the locking hook 6 can automatically engage after passing the locking plate 84.

[0038] As another preferred embodiment, in order to achieve efficient filtration and convenient cleaning of the perfume, a complete filtration device is also provided inside the canister 1. The device includes a filter assembly 78 that can be picked up and put in as a whole, and a disassembly mechanism 7 for quickly fixing or releasing the filter assembly 78 inside the canister 1.

[0039] Furthermore, as a specific definition of the structure of the filtration device, the filter assembly 78 includes a connecting post 784 serving as a handle. Along its length, from top to bottom, the connecting post 784 is fixedly connected to a coarse filter 781, a medium filter 782, and a fine filter 783 with progressively smaller pore sizes. Correspondingly, the inner wall of the tank 1 is also fixedly connected from top to bottom with retaining rings 75, 76, and 77. The inner diameter of the three retaining rings is adapted to the outer diameter of the three filter layers, and the inner diameter decreases progressively. They are used to support the coarse filter 781, the medium filter 782, and the fine filter 783 one-to-one, thereby achieving rapid radial and axial positioning of the filter assembly 78.

[0040] Furthermore, as a specific definition of the disassembly mechanism 7, it includes a storage ring 71 fixed above the inner wall of the tank 1. A connecting shaft 72 is rotatably connected to the storage ring 71 via a pin. An arc-shaped rod 73 is fixedly connected to one end of the connecting shaft 72. A limiting bead 74 for auxiliary positioning is slidably sleeved on the body of the arc-shaped rod 73. By manually operating the arc-shaped rod 73 to rotate around the connecting shaft 72, it can be used to lock and fix or unlock and release the filter assembly 78.

[0041] The working principle is as follows:

[0042] When the filter device needs to be installed or disassembled for cleaning, the operator first places the filter assembly 78, which integrates the coarse filter 781, the medium filter 782, and the fine filter 783, inside the tank 1 by holding the connecting column 784. Because the inner diameters of the retaining rings 75, 76, and 77 gradually decrease, the filter assembly 78 will accurately fall onto the corresponding retaining rings under the action of gravity to achieve positioning. Then, the operator moves the arc-shaped rod 73 in the disassembly mechanism 7 to rotate it around the connecting shaft 72 and lock it onto the upper part of the filter assembly 78. The limiting bead 74 plays an auxiliary limiting role, thereby completing the installation and locking of the filter assembly 78. Disassembly is carried out in the reverse order. First, the arc-shaped rod 73 is rotated to unlock it, and then the connecting column 784 can be lifted to remove the filter assembly 78 as a whole. The whole process does not require complicated tools and achieves quick installation and disassembly.

[0043] When the lid 5 needs to be opened or closed for maintenance or material addition, to open it, the operator pulls the horizontal bar 83 of the locking mechanism 8 outward. The horizontal bar 83, through the connecting plate 82 and the sliding rod 85, drives the locking plate 84 to move outward against the elastic force of the spring 86. When the locking plate 84 disengages from the locking hook 6, the lid 5 can be lifted upward. To close it, the operator presses the lid 5 downward. When the locking hook 6 contacts the locking plate 84, its downward-sloping guide surface pushes the locking plate 84 forward. Continuing to press the lid 5 downward, when the hook part of the locking hook 6 passes the locking plate 84, the spring 86 pushes the locking plate 84 to instantly reset and lock behind the locking hook 6, thus achieving rapid pressing and self-locking of the lid 5.
