Description

Technical Field

[0001] The present application relates to the technical field of plate and frame filter presses, and in particular to a plate and frame discharge port for arsenic sulfide slag. Background Art

[0002] The plate and frame filter press is a form of plate and frame filter press specifically designed for solid-liquid separation of arsenic sulfide slag. During the arsenic sulfide slag treatment process, the plate and frame filter press uses a combination of filter cloth and filter plates to compress and filter the arsenic sulfide slag, separating the solid particles from the liquid.

[0003] The operating principle of the plate and frame filter press for arsenic sulfide slag is primarily based on the filtration of the filter cloth and the compression of the filter plates. When the liquid containing arsenic sulfide slag enters the plate and frame filter press, solid particles in the liquid are trapped by the filter cloth, forming a filter cake; the filtrate then flows out through the filter cloth, achieving solid-liquid separation. Simultaneously, the filter plates further squeeze out moisture from the filter cake through compression, increasing the solid content of the filter cake.

[0004] Operators at the Yimen Copper Industry Sulfuric Acid Plant discovered that when unloading arsenic sulfide slag from the plate frame for wastewater treatment, the discharge port was not sealed tightly, and the arsenic sulfide slag often fell outside the discharge port, posing a major safety hazard.

[0031] The above description is merely an optional embodiment of the present application and is not intended to limit the present application.

[0032] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings to facilitate understanding by technical personnel.

[0033] Example 1:

[0034] See also Figure 1 and Figure 2 , an arsenic sulfide slag plate-frame discharge port, comprising a conical hopper 1, the arsenic sulfide slag plate-frame discharge port further comprising:

[0035] A plate frame 2 fixed to the upper end of the conical hopper 1;

[0036] A first sealing plate 3 is sealingly connected to one side of the lower end of the plate frame 2 and is located in the conical hopper 1;

[0037] a second sealing plate 4 sealingly connected to the other side of the lower end of the plate frame 2 and located inside the conical hopper 1;

[0038] The angle a formed between the first sealing plate 3 and the second sealing plate 4 and the lower end surface of the plate frame 2 is greater than the angle b formed between the first side plate 5 and the second side plate 6 of the conical hopper 1 and the lower end surface of the plate frame 2.

[0039] Specifically, if Figure 3As shown, in conventional technology, the plate frame 2 and the conical hopper 1 are not tightly sealed, and arsenic sulfide slag can spill out from the gap between them and fall outside the discharge port. Since arsenic sulfide slag is a hazardous waste, this poses a significant safety hazard. In this embodiment, the plate frame 2 is fixedly connected to the upper end of the conical hopper 1, and a first sealing plate 3 and a second sealing plate 4 are sealed to both sides of the lower end of the plate frame 2. The plate frame 2, the first sealing plate 3, and the second sealing plate 4 form a new sealed discharge hopper that is connected from top to bottom, thereby avoiding the safety hazard caused by arsenic sulfide slag falling outside the discharge port.

[0040] At the same time, the present application increases the inclination angle of the cone surface by making the angle a formed by the first sealing plate 3 and the second sealing plate 4 with the lower end surface of the plate frame 2 greater than the angle b formed by the first side plate 5 and the second side plate 6 of the conical hopper 1 with the lower end surface of the plate frame 2, thereby improving the unloading speed and avoiding waste accumulation in the unloading hopper.

[0041] Example 2:

[0042] See also Figure 1 Based on embodiment 1, optionally, the angle a ranges from 60° to 80°.

[0043] Specifically, in conventional technology, the angle b formed between the first and second side plates 5, 6 of the conical hopper 1 and the lower end surface of the plate frame 2 is typically less than 50°, resulting in slow discharge and allowing waste to easily accumulate in the discharge hopper and spill out from gaps. In this embodiment, the angle a formed between the first and second sealing plates 3, 4 and the lower end surface of the plate frame 2 is set to between 60° and 80° to ensure faster discharge speed.

[0044] Optionally, a discharge port 7 is provided at the lower end of the conical hopper 1 .

[0045] Specifically, the upper end of the discharge port 7 is fixedly connected to the lower end of the conical hopper 1 , and the conical hopper 1 can provide support for the discharge port 7 , and the arsenic sulfide slag is discharged through the discharge port 7 to a designated area for processing.

[0046] Optionally, the lower ends of the first sealing plate 3 and the second sealing plate 4 are sealedly connected to both sides of the upper end of the discharge port 7 respectively.

[0047] Specifically, the sealed connection avoids the generation of gaps, thereby preventing slag from accumulating in the gaps.

[0048] Optionally, the first sealing plate 3 and the second sealing plate 4 are symmetrical about the vertical center line of the plate frame 2 .

[0049] Specifically, the symmetrical arrangement of the first sealing plate 3 and the second sealing plate 4 can form a more uniform stress-bearing structure, thereby enhancing the overall strength. The symmetrical structure can more effectively disperse stress and reduce the risk of structural failure.

[0050] Optionally, the first sealing plate 3 and the second sealing plate 4 are smooth panels.

[0051] Specifically, smooth panels significantly reduce friction between the material and the unloading plate, making the unloading process smoother. The smooth panel design reduces the contact area and friction between the material and the plate surface, thereby reducing the likelihood of material sticking. This not only helps keep the unloading plate clean but also reduces equipment failures and downtime caused by material sticking. With lower friction, smooth panels also experience less wear, which means a longer service life for the panel and reduces the frequency and cost of replacement. Smooth panels are also easier to clean and maintain, further extending the life of the equipment.

[0052] Optionally, the first sealing plate 3 and the second sealing plate 4 are made of smooth hard PVC plates.

[0053] Specifically, the surface of PVC boards is coated with a special polymer material approximately 0.1 to 0.5 mm thick, resulting in high wear resistance and a relatively long service life. The high surface hardness of PVC boards makes them resistant to scratches and abrasion, allowing them to remain flat and smooth for extended periods. Rigid PVC also offers excellent mechanical properties, including a high elastic modulus, and the ability to withstand certain external impacts. PVC is also chemically stable and exhibits excellent corrosion resistance, making it suitable for use in a variety of harsh chemical environments. PVC boards are also easy to replace and maintain.

[0054] It should be noted that the structures and / or installation methods not detailed in this application are known to those skilled in the art in combination with common knowledge and / or existing technologies, and are not the focus of disclosure in this application and will not be further elaborated here.

[0055] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
