Abstract
Description
Technical Field
[0001] This utility model relates to the field of warehouse safety technology, and more specifically to an emergency device for accidents in solid material collection warehouses. Background Technology
[0002] Solid material collection devices are available in steel cylindrical and square structures, among others. These devices generally pose safety risks due to their large collection capacity and the susceptibility of the steel structure to deformation. As the device ages, the internal structure often deforms, and solid materials, when exposed to moisture, tend to clump together, making timely discharge difficult and causing the equipment to idle and falsely discharge materials, increasing the risk of collapse. A collapse of a solid material collection device has extremely serious consequences, often resulting in mass casualties. Even in cases of material blockage, handling is very difficult. In recent years, there have been numerous cases of solid material collection device collapses, causing significant economic losses and social impact on the company's normal operations.
[0003] Through practical production processes, it has been found that the main safety risk of various solid material collection devices is the technical problem of inadequate emergency response devices in the aforementioned accidents. Utility Model Content
[0004] 1. Technical problem to be solved by the utility model
[0005] In view of the above-mentioned defects in existing solid material collection devices, this utility model provides an emergency device for solid material collection bins. By cooperating with a high-level alarm and an ash discharge valve, the alarm and ash discharge valve switch signals are connected to the DCS control room to prevent accidents and eliminate safety hazards.
[0006] 2. Technical Solution
[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0008] An emergency device for solid material collection hopper includes a high-level alarm and a low-level alarm fixedly connected to the upper and lower inner walls of the hopper, respectively, and a discharge pipe connected to the outer side of the inner wall near the bottom of the hopper. A discharge valve is connected to the wall of the discharge pipe. The high-level alarm, low-level alarm, and discharge valve are all connected to a DCS control room. The discharge valve can be designed as a pneumatically automatic interlock, with its switch signal connected to the DCS control room. Once a high-level alarm is detected or the unloading pump is found to be running dry and falsely discharging, the discharge valve is opened promptly to discharge the solid material from the hopper, reducing the overall weight of the hopper, preventing accidents, eliminating safety hazards, and providing important safety assurance for safe production.
[0009] Further technical solutions also include a discharge pump connected to the bottom of the collection hopper.
[0010] A further technical solution involves installing a discharge valve between the collection hopper and the discharge pump. The discharge valve is also connected to the DCS control room via a signal. The discharge valve is preferably pneumatically controlled, and the pneumatic starter has high sensitivity, which can effectively prevent valve jamming and protect personnel.
[0011] A further technical solution involves assembling multiple parallel hoppers to mitigate the risks associated with filler material and prevent blockages during accidental discharge.
[0012] 3. Beneficial effects
[0013] Compared with the prior art, the technical solution provided by this utility model has the following advantages:
[0014] This utility model relates to an emergency device for solid material collection bins. Each discharge valve is pneumatically activated, and the signal is connected to the DCS control room. Operators can immediately activate the discharge in an emergency, reducing the weight of the solid material collection bin. The pneumatic activation device is highly sensitive and can effectively prevent valve jamming, thus playing a role in personnel safety protection. Attached Figure Description

[0017] To further understand the contents of this utility model, a detailed description of the utility model is provided in conjunction with the accompanying drawings.
[0018] Example 1
[0019] The emergency device for solid material collection bin accidents in this embodiment is installed in the collection bin 2 below the dust collector 1, such as... Figure 1As shown, the system includes a high-level alarm 3 and a low-level alarm 4 fixedly connected to the upper and lower inner walls of the collection hopper 2, respectively; a discharge pipe 6 connected to the outer side of the bottom inner wall of the collection hopper 2; and a discharge pump 7 connected to the bottom of the collection hopper 2. The discharge pipe 6 is connected to an ash discharge valve 5, and can be made of ordinary carbon steel. The high-level alarm 3, low-level alarm 4, and ash discharge valve 5 are all connected to the DCS control room. DCS refers to a Distributed Control System. The ash discharge valve 5 can be designed as a pneumatic automatic interlock. The pneumatic starting device has high sensitivity and can effectively prevent valve jamming. The switch signal is connected to the DCS control room. The discharge pipe 7 should preferably be Φ100mm, and its height from the ground should preferably be slightly greater than 1m. Using carbon steel pipe as the discharge pipe 7 is low-cost, easy to install, and quick.
[0020] The emergency device for solid material collection bins in this embodiment can promptly open the ash discharge valve 5 when the high-level alarm 3 or the unloading pump 7 is found to be running dry and falsely discharging material in the collection bin 2. This will allow the solid material in the bin to be discharged from the collection bin 2 in a timely manner, reducing the weight of the entire bin, preventing accidents, eliminating safety hazards, and providing important safety guarantees for safe production.
[0021] Example 2
[0022] The emergency device for solid material collection silos in this embodiment has the same basic structure as in Embodiment 1, with the following differences or improvements: a discharge valve 8 is installed between the collection hopper 2 and the discharge pump 7. The discharge valve 8 is also connected to the DCS control room. The discharge valve 8 is preferably pneumatically controlled, and the pneumatic start device has high sensitivity, which can effectively prevent valve jamming and protect personnel. Multiple collection hoppers 2 are arranged in parallel to distribute the risk of packing and prevent material blockage during accidental discharge. One, two or more discharge pipes 6 can be installed on one hopper. The number of pipes can be arbitrarily installed according to the size of the collection hopper 2 and production needs. The number of pipes installed is not limited, and the number of pneumatic start signals is also not limited. They can be combined in one, two or more groups. The installation is convenient, simple and low-cost.

The actual structure and manufacturing steps are not limited to these. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
