Description

Technical Field

[0001] The invention relates to the technical field of sulfur refining, and in particular to a bag breaking and screening device for sulfur paste feeding. Background Art

[0002] Industrial sulfur is an important chemical product and basic industrial raw material, widely used in chemical, light industry, pesticide, rubber, dye, papermaking and other industrial sectors. Solid industrial sulfur is in the form of blocks, powder, granules and flakes, and is yellow or light yellow. The melting point of sulfur is 112.8-119.3℃, the boiling point is 444.6℃, it is insoluble in water, slightly soluble in alcohol and ether, and easily soluble in carbon dioxide, carbon tetrachloride and benzene. This product is a secondary flammable material with a natural temperature of 205℃. Its dust or vapor can form an explosive mixture with air, and it is a flammable solid dangerous good.

[0003] From a toxicological point of view, sulfur is a low-toxic hazardous chemical, but it is still highly toxic. Long-term use can cause severe toxicity. The chronic toxicity of dozens of grams of sulfur accumulation is enough to damage the liver and kidneys. Studies have confirmed that sulfur damages the renal tubules and glomeruli, causing interstitial nephropathy, renal necrosis, etc., which can lead to renal failure and even death. Sulfur contains a lot of heavy metals. Eating a small amount will cause certain damage to the human internal organs. Long-term use will cause interstitial nephropathy, mental decline, and stupidity. In particular, sulfur dioxide produced when sulfur is oxidized is highly toxic to the human body. It reacts violently when it comes into contact with halogens, metal powders, etc. Sulfur is a poor conductor and is prone to static charge during storage and transportation, which can cause sulfur dust to catch fire. Dust or steam will form an explosive mixture when mixed with air or oxidants.

[0004] Sulfur paste is sulfur containing water (30-40% wt.), which is a flammable solid with a density of 1300-2000 kg / m3. Sulfur powder can be made from sulfur paste, which is generally stored in ton bags. Therefore, when processing sulfur paste, the ton bags must be cut open first to allow the sulfur paste in the ton bags to flow out. At present, the ton bags are mostly cut open manually. After the ton bags are cut open, the sulfur paste flows out. The direct contact of the workers with the sulfur paste will seriously endanger their health. Summary of the invention

[0070] Embodiment 1:

[0071] The embodiment of the present invention provides a bag breaking and screening device for sulfur paste feeding, such as Figure 1-6 As shown, including:

[0072] A first box body 1, wherein a support plate 2 is arranged inside the first box body 1, and a cutting knife 3 is arranged on the upper surface of the support plate 2;

[0073] A second box body 4, wherein the second box body 4 is disposed at an upper end of the first box body 1, and the second box body 4 is communicated with the first box body 1;

[0074] A screening component is arranged in the second box 4.

[0075] The working principle and beneficial effects of the above technical solution are as follows: the device comprises a first box body 1, a sealing plate is arranged at the upper end of the first box body 1, a support plate 2 is arranged inside the first box body 1, a cutting knife 3 is arranged on the upper surface of the support plate 2, after the ton bag storing the sulfur paste is put into the first box body 1, the cutting knife 3 is located directly below the ton bag, and under the action of gravity, the ton bag moves downward, and when the lower part of the ton bag contacts the cutting knife 3, the cutting knife 3 can pierce the ton bag, and a beating system is also arranged inside the first box body 1, which can beat the ton bag so that all the sulfur paste can flow out, and is composed of two sets of air bags, which can cross-beat the bag body through control to achieve a flow-aiding effect, and when the sulfur paste is leaked out, it is prevented from remaining in the bag by residual sulfur paste, and the residual sulfur paste is beaten by air flow. The sulfur paste is left to fall out, and then flows into the second box body 4. After being screened by the screening component, it only needs to flow into the next sequence. By setting up a bag breaking and screening device, the ton bag can be brought into contact with the cutter 3 under the gravity of the ton bag, thereby realizing the bag breaking processing of the ton bag. The cutter 3 adopts a cross multi-row knife, and the material of the cutter 3 is 2Gr13. It can break the bag once and neatly to avoid the damaged ton bag after the bag breaking from mixing into the material. No human participation is required during bag breaking, which replaces the manual bag breaking operation of the ton bag, reduces the direct contact between workers and sulfur paste, and effectively protects the health of workers. At the same time, the bag breaking and screening device is a closed space, which avoids the leakage of sulfur dust when the sulfur paste flows out, and can also protect the workshop environment and reduce dust pollution.

[0076] Example 2

[0077] On the basis of the above-mentioned embodiment 1, the cutting knives 3 are provided in multiple rows, and the multiple rows of cutting knives 3 are arranged in a cross shape on the upper surface of the support plate 2 .

[0078] The working principle and beneficial effects of the above technical solution are as follows: the cutters 3 are arranged in multiple rows and in a cross shape, and can cut multiple openings at the bottom of the ton bag, thereby accelerating the outflow of the sulfur paste in the ton bag.

[0087] A breaking box 12 is arranged below the downwardly inclined side of the screening plate 5 , and a breaking assembly is arranged in the breaking box 12 .

[0088] The working principle and beneficial effects of the above technical solution are as follows: when the sulfur paste flows into the second box body 4, the sulfur paste falls on the screening plate 5. A number of screening holes are arranged inside the screening plate 5. The sulfur paste that meets the preset diameter will directly pass through the screening plate 5 and then flow under the screening plate 5. The sulfur paste that does not meet the preset diameter will be blocked by the screening plate 5. The length of the second spring 9 is greater than the length of the first spring 6. Therefore, the blocked sulfur paste slides downward along the upper surface of the screening plate 5, and then the sulfur paste slides into the breaking box 12. The breaking component breaks up the sulfur paste in the breaking box 12 until the sulfur paste meets the preset diameter and falls into the bottom of the second box body 4. By setting the screening component, the sulfur paste can be screened. By setting the first spring 6 and the second spring 9, the falling sulfur paste can be buffered to prevent the sulfur paste from damaging the screening plate 5.

[0145] On the basis of any one of Embodiments 1-8, further comprising:

[0146] A counter, which is arranged on the inner wall of the first box body 1 and is used to detect the number of cutting times of the cutting knife 3;

[0147] A concentration sensor, which is arranged on the inner wall of the first box 1 and is used to detect the average concentration of dust in the first box 1;

[0148] A particle collector, which is arranged on the inner wall of the first box 1 and is used to detect the average radius of dust in the first box 1;

[0149] An alarm, which is arranged on the outer wall of the first box body 1;

[0150] A second controller, which is arranged on the outer wall of the first box 1, and is electrically connected to the counter, the concentration sensor, the particle collector, and the alarm respectively;

[0151] The second controller controls the alarm to work based on the counter, the concentration sensor, and the particle collector, comprising the following steps:

[0152] Step 1: Based on the detection value of the counter, the total pressure on the cutting knife 3 is calculated by formula (1):

[0153]

[0154] Wherein, F1 is the total pressure on the cutting knife 3, N is the number of cutting times of the cutting knife 3 detected by the counter, m1 is the total weight of the ton bags put into the first box 1, and g is the acceleration of gravity, which is 9.8 m / s. 2 , h is the vertical distance from the cutting knife 3 to the upper end of the first box body 1, and t1 is the preset time length of the cutting knife 3 to cut each ton bag;

[0155] Step 2: Based on the calculation result of step 1 and the detection values ​​of the concentration sensor and the particle collector, the actual wear degree of the cutting knife 3 is calculated by formula (2):

[0156]

[0157] Wherein, δ is the actual wear degree value of the cutting knife 3, ε1 is the viscosity of the dust in the first box 1, ε2 is the air viscosity in the first box 1, r1 is the average radius of the dust in the first box 1 detected by the particle collector (several dusts are detected by the particle collector and the average value is calculated), θ1 is the preset surface tension of the dust in the first box 1, S1 is the surface area of ​​the cutting knife 3, ρ1 is the average concentration of the dust in the first box 1 detected by the concentration sensor, ρ2 is the air concentration in the first box 1, μ is the roughness coefficient of the surface of the cutting knife 3, l1 is the thickness of the cutting knife 3, and ln is the natural logarithm;

[0158] Step 3: The second controller compares the actual wear value of the cutting knife 3 with the preset wear value of the cutting knife 3. When the actual wear value of the cutting knife 3 is greater than the preset wear value of the cutting knife 3, the second controller controls the alarm to issue an alarm prompt.

[0159] The working principle and beneficial effects of the above technical solution are as follows: when the ton bag filled with sulfur paste is put into the first box body 1, the ton bag moves downward under the action of gravity and contacts the cutter 3, and the ton bag is broken by the cutter 3. The cutter 3 will be seriously worn after long-term operation. Therefore, a counter is set in the first box body 1 to detect the number of cutting times of the cutter 3, and then the total pressure on the cutter 3 is accurately calculated by formula (1). According to the calculation result of formula (1), the actual wear degree value of the cutter 3 can be calculated by improving formula (2). In the process of breaking the bag, the sulfur dust with viscosity will adhere to the surface of the cutter 3, affecting the cutting performance of the cutter 3. Therefore, in the calculation process, the viscosity of the dust in the first box body 1 is comprehensively considered, and the particle collector is used to detect the total pressure on the cutter 3. The average radius of the dust is used to calculate the friction between the dust particles and the surface of the cutting knife 3, wherein the roughness coefficient of the surface of the cutting knife 3 ranges from 0.6 to 0.75. Combined with the wear caused by the dust particles on the surface of the cutting knife 3, the actual wear degree of the cutting knife 3 can be accurately calculated. The second controller is provided with a preset wear degree value of the cutting knife 3. The second controller can compare the actual wear degree value with the preset wear degree value. When the actual wear degree value is greater than the preset wear degree value, it means that the cutting knife 3 is severely worn, which will reduce the bag breaking efficiency. At this time, the second controller controls the alarm to send an alarm prompt, thereby reminding the staff to replace the cutting knife 3 in the first box body 1, thereby ensuring the bag breaking performance of the cutting knife 3 on ton bags and improving the bag breaking efficiency.
