Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary equipment for paint mixing kettles, and more specifically, to a safety protection device for paint mixing kettles. Background Technology
[0002] Currently, the paint mixing tanks used in paint manufacturing plants typically have a semi-covered structure on top, meaning one half is covered by a lid and the other half has an observation port. While this structure facilitates observation of the internal working conditions, it also poses serious safety hazards, with frequent accidents involving operators falling into the tank while working on top. Furthermore, dust and debris can easily fall into the tank through the open observation port, affecting product quality.
[0003] In existing technologies, several guardrails are typically installed above the observation port to prevent falls. However, gaps exist between the guardrails, posing a risk of people stepping into gaps or getting their legs stuck, and the dust prevention issue remains unresolved. Therefore, there is an urgent need in the field for an integrated safety protection device that can effectively solve both fall prevention and dust prevention problems. Utility Model Content
[0004] 1. Technical problem to be solved: In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a safety protection device for paint mixing kettle, which effectively solves the dual problems of operators easily falling from the observation port and dust and debris easily falling into the paint mixing kettle.
[0005] 2. Technical Solution: To solve the above problems, the present invention adopts the following technical solution.
[0006] A safety protection device for a paint mixing kettle includes a paint mixing kettle body. A lid is provided on one half of the top half of the paint mixing kettle body, and an observation port is provided on the other half. A plurality of uprights are fixedly connected to the top of the paint mixing kettle body and are evenly distributed around the lid. The upper ends of the plurality of uprights are jointly supported by a ring-shaped protective railing. A ring-shaped dust cover is fixedly provided on the inner side of the ring-shaped protective railing. A plurality of equally spaced protective crossbars are fixedly connected between the inner walls of the observation port.
[0007] Preferably, the annular guardrail consists of an arc-shaped fixing sleeve and an arc-shaped sliding rod; the arc-shaped fixing sleeve is fixedly connected to the upper end of the post; the arc-shaped sliding rod is slidably fitted into the internal cavity of the arc-shaped fixing sleeve; the overall arc length of the arc-shaped sliding rod is greater than the arc length of the arc-shaped fixing sleeve, and a limiting block is fixedly provided at one end of the arc-shaped sliding rod to prevent it from coming out of the arc-shaped fixing sleeve; a locking threaded groove is provided on the outer side wall of the other end of the arc-shaped sliding rod; a first locking hole is provided on the side wall of the arc-shaped fixing sleeve corresponding to the position of the locking threaded groove; a first locking bolt passes through the first locking hole and can be screwed into the locking threaded groove to lock the relative position of the arc-shaped sliding rod and the arc-shaped fixing sleeve.
[0008] Preferably, the arc-shaped fixing sleeve and the arc-shaped sliding rod have the same radius of curvature. When the arc-shaped sliding rod extends to its maximum position, one end with the locking thread groove extends into the cavity of the arc-shaped fixing sleeve and aligns with the first locking hole, so that the annular guardrail forms a complete ring.
[0009] Preferably, the annular dust cover includes a horizontally arranged mounting ring, which is fixedly connected to the inner side of the annular guardrail; a T-shaped annular groove is formed on the bottom surface of the mounting ring along its circumference; a T-shaped slider is slidably embedded in the T-shaped annular groove; a transparent cover plate that can cover the observation port is fixedly connected to the bottom of the T-shaped slider; a flexible sealing curtain is fixedly connected to the bottom edge of the transparent cover plate.
[0010] Preferably, the top surface of the mounting ring is provided with a second locking hole, which is connected to the T-shaped annular groove below; the two sides of the T-shaped slider are provided with fixed threaded holes symmetrically; a second locking bolt passes through the second locking hole and can be screwed into either of the fixed threaded holes to lock the T-shaped slider and the transparent cover plate in the circumferential position on the mounting ring.
[0011] Preferably, the overall length of the T-shaped slider and the transparent cover plate is greater than the inner circumference of the mounting ring, so that the T-shaped slider can slide cyclically within the T-shaped annular groove.
[0012] Preferably, the flexible sealing curtain is an annular curtain made of flexible material, the width of which is greater than the depth of the observation port, and is configured such that when the transparent cover plate covers the observation port, it hangs down to block the gap between the entire circumferential sidewall of the observation port and the transparent cover plate. Preferably, the transparent cover is an acrylic sheet.
[0013] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this utility model has the following advantages: (1) High safety: The ring-shaped guardrail, consisting of an arc-shaped fixing sleeve and an arc-shaped sliding rod, forms a complete closed protective ring around the observation port and the pot lid, fundamentally preventing the possibility of personnel falling. The protective crossbar installed inside the observation port provides double protection.
[0014] (2) Good sealing and dustproof performance: The observation port can be completely sealed during non-operation periods through a sliding transparent cover and a flexible sealing curtain connected to the bottom. The flexible sealing curtain hangs down by its own weight and fits tightly against the side wall of the observation port, effectively preventing dust and debris from falling into the vessel from any gaps.
[0015] (3) Reasonable structure and no interference between components: The guardrail and the dust cover are two independent functional modules installed in different positions. Their movement paths do not intersect, thus completely avoiding movement interference between components.
[0016] (4) Easy to operate: Both the arc-shaped sliding rod and the transparent cover are equipped with a simple bolt locking mechanism, which can quickly fix them in the working position or open position, making it convenient for personnel to operate and observe.
[0017] It should be noted that the structures not described in this utility model are the same as or can be implemented using existing technology, and will not be elaborated here, as they do not involve the design points and improvement directions of this utility model. Attached Figure Description

Detailed Implementation
[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] See Figure 1-4 As shown, this utility model discloses a safety protection device for a paint mixing kettle, comprising a paint mixing kettle body 1. A lid 2 is provided on one half of the top of the paint mixing kettle body 1, and an observation port 21 is provided on the other half. Multiple uprights 3, evenly distributed around the lid 2, are fixed to the top of the paint mixing kettle body 1 by bolts or welding. The upper ends of the multiple uprights 3 collectively support and are fixedly connected to a ring-shaped protective railing 4. A ring-shaped dust cover 5 is fixed to the inner side of the ring-shaped protective railing 4 by welding or fasteners. Multiple equally spaced protective crossbars 22 are welded between the inner walls of the observation port 21, serving as the most basic fall protection barrier.
[0025] The circular guardrail 4 consists of an arc-shaped fixing sleeve 41 and an arc-shaped sliding rod 42. The arc-shaped fixing sleeve 41 is preferably a semi-circular steel tube, fixedly connected to the upper end of the post 3. The arc-shaped sliding rod 42 is also a semi-circular arc-shaped steel tube, but its overall arc length is slightly greater than that of the arc-shaped fixing sleeve 41, allowing it to slide smoothly within the internal cavity of the arc-shaped fixing sleeve 41. A limit block 421 is welded to one end of the arc-shaped sliding rod 42, its size being larger than the port of the arc-shaped fixing sleeve 41, to prevent the sliding rod from completely detaching. A locking threaded groove 422 is machined on the outer wall of the other end of the arc-shaped sliding rod 42. The position of this locking threaded groove 422 is designed so that when the arc-shaped sliding rod 42 is pulled out to its maximum stroke, it can just completely enter the cavity of the arc-shaped fixing sleeve 41 and align with the first locking hole 411 thereon.
[0026] On the side wall of the arc-shaped fixing sleeve 41, at the end position of the sliding trajectory of the locking threaded groove 422, a first locking hole 411 is provided. When the arc-shaped sliding rod 42 is pulled out and forms a complete ring with the arc-shaped fixing sleeve 41, the locking threaded groove 422 moves exactly to the first locking hole 411. At this time, by passing the first locking bolt 412 through the first locking hole 411 and screwing it into the locking threaded groove 422, the entire annular guardrail 4 can be locked in a closed state, thus providing a safety enclosure.
[0027] The annular dust cover 5 includes a horizontally positioned mounting ring 51, which is fixed to the inner side of the annular guardrail 4 by support legs. A T-shaped annular groove 511 is machined along the entire circumference of the bottom surface of the mounting ring 51. A T-shaped slider 52 is slidably fitted into this groove. A transparent acrylic cover plate 53 is fixedly connected to the bottom of the T-shaped slider 52 by bolts or welding. As a preferred embodiment of this invention, the overall length of the T-shaped slider 52 and the transparent cover plate 53 is designed to be greater than the inner circumference of the mounting ring 51. This dimensional relationship ensures that the T-shaped slider 52 can slide cyclically within the T-shaped annular groove 511 without detaching from either end of the groove, greatly improving the reliability and service life of the equipment.
[0028] A second locking hole 512 is provided on the top surface of the mounting ring 51, which communicates with the T-shaped annular groove 511 below. Fixed threaded holes 521 are symmetrically machined on both sides of the T-shaped slider 52. When the transparent cover 53 is pushed to the position completely covering the observation port 21, one of the fixed threaded holes 521 will align perfectly with the second locking hole 512. At this time, the second locking bolt 55 is passed through the second locking hole 512 and screwed into the fixed threaded hole 521, thus securely locking the transparent cover 53 in the closed position. Similarly, when the transparent cover 53 is pushed above the pot lid 2, it can be locked in the open position by the second locking bolt 55 engaging with the fixed threaded hole 521 on the other side.
[0029] A flexible sealing curtain 54 is fixedly connected to the bottom edge of the transparent cover 53 by adhesive or pressure strip. This sealing curtain can be made of materials such as rubber, silicone, or flexible plastic cloth. As a key sealing structure of this utility model, the width of the flexible sealing curtain 54 is designed to be greater than the depth of the observation port 21. Therefore, when the transparent cover 53 covers the observation port 21, the flexible sealing curtain 54 hangs down naturally due to its own weight and completely covers the gap between the entire circumferential sidewall of the observation port 21 and the transparent cover 53, forming a highly effective three-dimensional seal to prevent dust from entering.
[0030] The working principle of this utility model is as follows: When the paint mixing tank is operating normally, the arc-shaped sliding rod 42 is pulled out and locked with the first locking bolt 412 to form a ring-shaped guardrail. At the same time, the transparent cover plate 53 is slid above the observation port 21 and locked with the second locking bolt 55, and the flexible sealing curtain 54 hangs down to achieve a seal. When it is necessary to feed materials or observe at close range, the second locking bolt 55 can be opened, the transparent cover plate 53 can be pushed above the pot lid 2 and locked. At this time, personnel are still protected by the ring-shaped guardrail 4 and can safely carry out operations.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
