Description

Technical Field

[0001] This utility model relates to the field of sealed chamber technology for weighing industrial materials, specifically the structure of a sealed chamber for weighing chemical materials. Background Technology

[0002] In the chemical production process, accurate weighing of chemical materials is a key step in ensuring production quality and safety. Many chemical materials have properties such as volatility, corrosiveness, and toxicity. If they are exposed to air during the weighing process, it will not only cause changes in the composition of the materials and affect product quality, but may also harm the health of operators and even cause safety accidents.

[0003] Existing sealed chambers have limited functionality, only allowing for simple sealed feeding and discharging. Furthermore, some sealed chambers with weighing functions often use a single weighing device, which cannot evenly distribute the weight under gravity, leading to weighing deviations. Additionally, sealed chambers require periodic depressurization, which necessitates manual depressurization by personnel, is time-consuming and labor-intensive. During depressurization, material may escape, polluting the environment and endangering the health of workers, posing safety hazards. The feeding and discharging speeds are also uncontrollable. While existing technical solutions to these problems may already exist, this proposal aims to provide a replacement or alternative technical solution. Utility Model Content

[0020] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example: Refer to Figure 1-3 The sealed chamber structure for weighing chemical materials includes four connecting blocks 1. Limiting plates 2 are mounted on the side walls of each of the four connecting blocks 1. A slide rail 3 is embedded in the opposite wall of each limiting plate 2. A slider 4 is slidably mounted on each slide rail 3. A bearing plate 5 is mounted between the four sliders 4. A weighing sensor 6 is embedded in the upper wall of each connecting block 1 below the bearing plate 5. An opening is machined at the center of the upper wall of the bearing plate 5. A limiting frame 7 is mounted on the upper wall of the bearing plate 5. A chamber body 8 is mounted on the upper wall of the bearing plate 5 within the limiting frame 7. A feed pipe 9 is mounted on the side wall of the chamber body 8 near the upper wall. A discharge pipe 10 is mounted on the lower wall of the chamber body 8 within the opening. An opening is machined on the front wall of the chamber body 8, and a stop door 11 is movably mounted on the opening. Two limiting buckles 12 are movably mounted on the front wall of the chamber body 8 to one side of the stop door 11. The rear wall of the stop door 11... The upper part is equipped with a first rubber sealing layer 13; the upper wall of the chamber 8 is machined with an assembly port, and two air filter layers 14 are installed in the assembly port. The upper wall of the chamber 8 is equipped with an opening and closing structure; the opening and closing structure includes a mounting frame 15, an electric cylinder 16, a connecting seat 17, a pressure plate 18, and a second rubber sealing layer 19; the mounting frame 15 is placed on the upper wall of the chamber 8 and located behind the assembly port, the electric cylinder 16 is placed on the lower wall of the crossbeam of the mounting frame 15, the connecting seat 17 is placed on the telescopic end of the electric cylinder 16, the pressure plate 18 is placed on the lower wall of the connecting seat 17, and the second rubber sealing layer 19 is placed on the lower wall of the pressure plate 18; telescopic limit rods 20 are respectively installed between the lower wall of the crossbeam of the mounting frame 15 and the pressure plate 18 and on both sides of the electric cylinder 16; a connecting plate 21 is respectively installed on the lower wall of each connecting block 1, and an electric valve 22 is respectively installed on the feed pipe 9 and the discharge pipe 10.

[0022] The specific working principle is as follows:

[0023] This device is assembled onto the downstream equipment via connecting plate 21 and connected to the upstream equipment via feed pipe 9. An external power supply is connected to power the device, and material is fed into the chamber 8 via feed pipe 9. As the weight of the chamber 8 increases, the weighing sensor 6 installed in connecting block 1 measures the weight and transmits the real-time weight reading to the programmable controller (PCC) mounted on it. The data from the four weighing sensors 6 remain consistent, improving the accuracy of the weighing data. When the weight reaches the set value, the weighing sensor 6 sends a signal, which the PCC receives and issues a control command. The electric valve 22 on feed pipe 9 closes to stop feeding, and the electric valve 22 on discharge pipe 10 on chamber 8 opens to discharge. During the material conveying and weighing intervals, the electric cylinder 16 on the mounting bracket 15 on chamber 8 drives the connecting seat 17 on its telescopic end to rise, thus limiting the telescopic movement. The rod 20 retracts, causing the pressure plate 18 to rise and release pressure. During pressure release, the material inside the chamber 8 is filtered and blocked by the air filter layer 14 to prevent overflow and contamination of the working environment. After pressure release, the electric cylinder 16 pushes the pressure plate 18 to reset, and the second rubber sealing layer 19 installed on the pressure plate 18 provides a seal. When cleaning the chamber is required, the operator turns the limit buckle 12 to open the baffle door 11 for cleaning. After cleaning, the baffle door 11 is closed, and the limit buckle 12 is turned to make the baffle door 11 fit tightly against the chamber 8. The first rubber sealing layer 13 installed on the baffle door 11 is used to increase the sealing layer. The slider 4 and slide rail 3 installed in the limit plate 2 on the connecting block 1 facilitate longitudinal flexibility and prevent shaking during weighing. The limit frame 7 is used to assist in limiting the chamber 8 and prevent the chamber 8 from shaking on the bearing plate 5. The electric valve 22 can also control the feeding speed and the discharge speed.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
