Description

Technical Field

[0002] During normal production of the plate and frame filter press, sulfur mud falls directly from the filter press to the ground, and is then loaded and transported by a forklift. During the temporary storage and transportation of the material, a small amount of desulfurization liquid carried by the sulfur mud will pollute the ground at the storage point and even cause infiltration pollution to the groundwater system. During the loading process, sulfur mud spilled by the forklift and attached to the wheels will also cause secondary pollution to the nearby road surface and ground. During the entire production, loading and transportation process of sulfur mud, the irritating odor emitted on site continues to cause harm to human health, and is accompanied by the risk of mechanical injury, which brings great disadvantages to safe and environmentally friendly production and huge environmental pressure;

[0003] Faced with the increasingly stringent safety and environmental protection situation, the company has made improvements, self-made sulfur mud funnel, and transformed the lower part into plastic coated ton bags for storage, and placed the plastic coated ton bags in the support frame to support the plastic coated ton bags (such as Figure 6 As shown), after the filter press is unloaded, the plastic-coated ton bags are placed in the inventory area with a forklift, packed and sealed to prevent the escape of irritating gases, and then replaced with new plastic-coated ton bags to continue unloading. The whole process achieves the goal of not directly falling to the ground and eliminates pollution to the environment. In the above process, when replacing new plastic-coated ton bags, a small amount of sulfur sludge will still fall to the ground, causing slight pollution, making it difficult to continuously recycle the sulfur sludge and avoid a small amount of sulfur sludge falling to the ground. At the same time, since the plastic-coated ton bags filled with sulfur sludge are heavy, it is difficult to transfer them conveniently.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content
