Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology. More specifically, this utility model relates to an observation device for a chromium anhydride discharge silo. Background Technology

[0002] Chromium anhydride is a chemical widely used in chemical, electroplating, and other industries, characterized by its strong acidity, corrosiveness, and hygroscopicity. Therefore, during the production and use of chromium anhydride, the observation and monitoring of whether there is blockage inside the discharge silo is crucial; hence, an observation device is usually installed on the top of the silo. During operation, the chromium anhydride in the discharge silo is filled into open filling containers through the discharge port. The chromium anhydride reaches a temperature of 50°C and then passes through a conveyor belt to the next process, the drying process, to remove any moisture present. Therefore, during the process of filling the containers and sealing them, the chromium anhydride will inevitably volatilize, and may exist in gaseous form in the workshop air. When gaseous chromium anhydride encounters the cooler temperature of the workshop ceiling, it condenses into a solid or liquid. The random falling of the condensed solids may damage the discharge silo observation device, affecting the safety of chromium anhydride production and the use of the observation device.

[0003] Utility model patent CN209260277U discloses a multi-compartment observation window for cleaning materials, including a window frame installed on the compartment body. A transparent observation panel is movably installed on the window frame. Two fixing grooves are provided on both sides of the transparent observation panel, and fixing pins and columns are movably installed in the two fixing grooves respectively. This utility model allows the transparent observation panel to be replaced when damaged, overcoming the previous disadvantage of being difficult to replace. However, the transparent observation panel of this device lacks effective protection, and its damage may cause impurities to fall into the compartment body, affecting the quality of the materials. Moreover, the replaceable setting of its transparent observation panel also results in poor sealing performance, which is not conducive to sealing the materials in the compartment body. Utility Model Content

[0004] One object of this invention is to solve the above-mentioned problems and / or defects, and to provide the advantages that will be described later.

[0005] To achieve these objectives and other advantages of this utility model, a chromium anhydride discharge bin observation device is provided, comprising: an observation window fixed to a reserved observation port in the discharge bin, and further comprising: a pair of fixing members arranged along opposite sides of the observation window;

[0006] A protective cover that can be detachably connected to a fastener to cover the surface of the observation window.

[0007] Preferably, it also includes a lighting mechanism fixed to the observation window and disposed near its edge.

[0008] Preferably, the fastener has a slot along its extension direction;

[0009] The protective cover has a raised edge that matches the slot.

[0010] Preferably, the protective cover is configured as two segments, which are connected by inserting the fasteners into slots on both sides and then close together.

[0011] Preferably, it further includes: a locking assembly disposed on the fastener and located at the joint of the two protective covers;

[0012] Each of the protective covers is provided with a locking groove that is adapted to the locking assembly for fixing;

[0013] The locking assembly includes: a housing disposed on the fixing member;

[0014] A set of locking pins that pass through the outer shell and are adapted to the locking grooves of the two protective covers;

[0015] A set of elastic elements that are connected and locked to the inner wall of the housing.

[0016] Preferably, the locking pin has a figure-eight shaped inclined surface at the end near the protective cover and a limiting platform at the end away from the protective cover to prevent the locking pin from coming out of the outer shell;

[0017] The locking groove is wider than the locking pin so that the two protective covers can be pressed tightly against each other after installation by the locking pin.

[0018] This utility model has at least the following beneficial effects: by setting an observation window that is sealed with the discharge hopper, the deliquescence of chromium anhydride inside the hopper is avoided; by setting a fixing component and a protective cover that is detachably connected to it, the condensed chromium anhydride can be prevented from falling and directly damaging the observation window, thus protecting it; and if the protective cover is damaged, it can be quickly replaced without affecting the sealing of the observation window and the normal production of chromium anhydride.

[0019] Other advantages, objectives and features of this invention will be apparent in part from the following description, and in part from the understanding of those skilled in the art through study and practice of this invention. Attached Figure Description

[0031] Example 1

[0032] A chromium anhydride discharge hopper observation device, the structure of which is as follows: Figure 1-3 As shown, it includes: an observation window 1 fixed to the reserved observation port of the discharge hopper, and also includes: a pair of fixing members 2 set along the opposite sides of the observation window 1;

[0033] A protective cover 3 is detachably connected to the fastener 2 and placed over the surface of the observation window 1.

[0034] In practical applications, the observation window 1 is positioned at an appropriate location in the discharge hopper and is made of acid-resistant materials, such as polytetrafluoroethylene (PTFE) or special glass, allowing for clear observation of the interior of the discharge hopper. The size and position of the observation window 1 can be adjusted according to actual needs. The observation window 1 is fixed to the discharge hopper by welding or other methods, with no gaps between them. A protective cover 3 is installed outside the observation window 1 to protect it from external environmental influences such as dust and moisture. The protective cover 3 can be made of transparent or semi-transparent materials (such as PTFE or special glass) and has good sealing performance with the fixing component 2.

[0035] Working principle: By setting up an observation window 1 that is sealed to the discharge hopper, the deliquescence of chromic anhydride inside the hopper is prevented. By setting up a fixing part 2 and a protective cover 3 that is detachably connected to it, the condensed chromic anhydride can be prevented from falling and directly damaging the observation window 1, thus protecting it. If the protective cover 3 is damaged, it can be quickly replaced without affecting the sealing of the observation window 1 and the normal production of chromic anhydride.

[0036] Example 2

[0037] This second embodiment is a preferred embodiment of the present invention, and its specific structure is as follows: Figure 2-3 As shown, based on embodiment 1, it discloses the following improvement: it also includes a lighting mechanism 4 fixed to the observation window 1 and disposed near its edge.

[0038] In practical applications, the lighting mechanism 4 can be configured with energy-saving, long-life lamps such as LED lights. The lighting mechanism 4 is fixed inside the observation window 1 to provide sufficient light so that the interior of the discharge hopper can be clearly observed even in low-light conditions. Positioning it close to the edge further ensures effective lighting while facilitating observation and minimizing the impact on the viewing angle.

[0039] Example 3

[0040] This third embodiment is a preferred embodiment of the present invention, and its specific structure is as follows: Figure 1-2 As shown, based on embodiment 1, the following improvement is disclosed: the fastener 2 is provided with a slot along its extension direction;

[0041] The protective cover 3 has a raised edge that matches the slot.

[0042] In practical applications, the fastener 2 is made of stainless steel to fix the protective cover 3. Its slot and the convex edge of the protective cover 3 form a push-pull structure, which facilitates quick replacement of the protective cover 3.

[0043] Example 4

[0044] This embodiment 4 is a preferred embodiment of the present invention, and its specific structure is as follows: Figure 1-3 As shown, based on embodiment 3, the following improvement is disclosed: the protective cover 3 is configured as two segments, which are connected by inserting the fasteners 2 into the slots on both sides and close together.

[0045] In practical applications, the protective cover 3 is configured with a U-shaped cross section to cover the outside of the observation window 1 and protect the observation window 1 and lighting mechanism 4 inside. It is configured as two separate pieces, which are fixed by the fasteners 2 on both sides to avoid interference with the observation window 1 and lighting mechanism 4 during installation, thus ensuring smooth and convenient installation.

[0046] Example 5

[0047] This fifth embodiment is a preferred embodiment of the present invention, and its specific structure is as follows: Figure 4-5 As shown, based on embodiment 4, it discloses the following improvement: it also includes a locking assembly 5 disposed on the fixing member 2 and located at the joint of the two protective covers 3;

[0048] Each of the protective covers 3 is provided with a locking groove 31 that is adapted to the locking assembly 5 for fixing;

[0049] The locking assembly 5 includes: a housing 51 disposed on the fixing member 2;

[0050] A set of locking pins 52 that pass through the outer shell 51 and are adapted to the locking grooves 31 of the two protective covers 3;

[0051] A set of elastic elements 53 connecting locking pins 52 to the inner wall of the outer casing 51.

[0052] The locking pin 52 has a figure-eight shaped inclined surface at the end near the protective cover 3, and a limiting platform 521 at the end away from the protective cover 3 to prevent the locking pin 52 from coming out of the outer shell 51.

[0053] The width of the locking groove 31 is greater than that of the locking pin 52, so that the two protective covers 3 are tightly pressed against each other under the action of the locking pin 52 after installation.

[0054] In practical applications, the elastic element 53 is configured as a spring; the locking components 5 are arranged in pairs on both sides of the protective cover 3 to fix its two ends respectively, thereby enhancing its stability; the locking components 5 are provided with a pair of locking pins 52 that fix the two protective covers 3 respectively; the side of the V-shaped inclined surface of the locking pin 52 close to the center is in close contact with the wall of the locking groove 31 of the protective cover 3 when it is fixed, and under the elastic force of the elastic element 53, it gives the fixed protective cover 3 a force that pushes it toward the center; thus, when the locking pin 52 fixes the protective cover 3, the two protective covers 3 are in close contact at the joint, improving the sealing and reliability of the protective cover 3.

[0055] Working principle: During installation, the two protective covers 3 are connected by inserting them into the slots on both sides of the fixing member 2 and closing together. During the closing process, the inclined surface of the locking pin 52 first contacts the protective cover 3 and is retracted into the outer shell 51 as the protective cover 3 moves. When the protective cover 3 moves to the contact point between the locking groove 31 and the locking pin 52, the locking groove 31 extends into the locking groove 31 and is fixed to the protective cover 3. The width of the locking groove 31 is greater than that of the locking pin 52, so that after the two protective covers 3 are installed, the side of the V-shaped inclined surface of the locking pin 52 close to the center is in close contact with the wall of the locking groove 31 of the protective cover 3. Moreover, at least one locking pin 52 does not move to the bottom of the locking groove 31 after the two protective covers 3 are pressed together, so that the locking pin 52 exerts a force towards the center on the fixed protective cover 3 under the elastic force of the elastic member 53. This makes the two protective covers 3 fit tightly at the joint, improving the sealing and reliability of the protective cover 3 and preventing the protective cover 3 from loosening.

[0056] The above solutions are merely illustrative examples of preferred embodiments, but are not limited thereto. When implementing this invention, appropriate substitutions and / or modifications can be made according to the user's needs.
