Quantitative direct bagging method for mud cake in filter press, mud cake bagging device and filter press

Abstract

The invention discloses a filter press mud cake quantitative direct-bagging method, a mud cake bagging device and a filter press. The filter press mud cake quantitative direct-bagging method is characterized by utilizing a space between the bottom surfaces of filter press filter plates to a floor to design so as to enable a mud cake to drop in a bag directly, i.e. a tray is arranged on a position located under the filter press filter plates, through holes are also formed in the tray, a loading bag is arranged on a position under the tray, a bag opening of the loading bag is arranged directly corresponding to the through holes, and after the mud cake is dropped in the tray from the filter press filter plates, the mud cake is dropped in the loading bag through the through holes in the tray, so that the mud cake is directly bagged. According to the filter press mud cake quantitative direct-bagging method, the mud cake bagging device and the filter press provided by the invention, the mud cake can be bagged directly so as to be prevented from dropping in the floor to pollute the floor and the working environment, so that the labor intensity of workers is reduced, the loading efficiency is improved, the construction cost is low, and the practicability is high.

Description

technical field [0001] The invention relates to a method for processing mud cake of a filter press, a working part of a filter press using the method to process mud cake of a filter press, and a filter press including the part, in particular to a quantitative method for mud cake of a filter press Direct bagging method, mud cake bagging device and filter press. Background technique [0002] Filter press is a commonly used solid-liquid separation equipment. It was used in chemical production in the early 18th century and is still widely used in environmental protection, chemical, pharmaceutical, metallurgy, dyestuff, food, brewing, ceramics and sewage treatment industries. [0003] A large amount of mud cakes will be formed after the filter press filters the muddy wastewater. Most of the mud cakes are foul-smelling and toxic, which will have another impact on the environment. Therefore, the mud cakes must be treated in a timely manner, that is, put the mud cakes Shipped in ba...

AI Technical Summary

Problems solved by technology

[0006] 1. The filter press has a large amount of mud cake processing, poor working environment, high labor intensity, and poisonous in many cases, so it is difficult to recruit personnel. Young people do not want to come even if they have a high salary, and it is difficult for the old to be qualified for such strenuous work;

[0007] 2. Since the filter press is one of the key links in water treatment, it must be treated in time to ensure the continuity and high quality of the upstream water treatment system. However, due to the frequent and heavy work of unloading mud and the poor working environment, the filtered mud cake contains odor and toxicity , No matter how diligent the workers are, they are passive and slow down, and intentionally reduce the frequency of mud unloading, which leads to problems in the upstream processing. Even if the managers vigorously urge the workers, it is difficult to see the effect, which increases the difficulty of user management of the filter press;

[0008] 3. Due to the difficulty of mud cake disposal, workers often discharge the toxic mud water in the mud pool directly and illegally without passing through the filter press to reduce the number of unloading and bagging of the filter press, thereby reducing the workload. Close one eye, causing serious pollution to the environment;

[0009] 4. Because many enterprises did not unload the sludge in time, the effect of the entire water treatment system was not good, and they suffered complaints from customers, which seriously caused serious environmental pollution and were severely punished by the Environmental Protection Bureau.

[0010] 5. Due to the long unloading time and heavy labor of the filter press, the enterprise needs to equip the filter press with high salaries for unloading mud and bagging personnel, as well as corresponding labor protection supplies. The long-term cost is far higher than the value of the filter press itself.

[0012] 1. Ordinary enterprises find ways to increase investment to improve the working environment, guarantee labor insurance supplies, improve workers' treatment, and strengthen internal management. However, due to the frequent unloading of filter presses, the workload of bagging is heavy, and the mud cake treatment is foul-smelling, toxic, and workers are motivated. Not high, the effect is not obvious;

[0013] 2. High-priced fully automatic filter presses are used in order to reduce labor intensity, but the reduction is limited. The labor intensity and harsh working environment are mainly due to the stench caused by mud cakes being turned over during mud removal and bagging. Currently, fully automatic filter presses The machine only plays an automatic role in turning over the board and unloading mud, and these tasks can only be done manually in a few minutes with low labor intensity. The physical work of shoveling and bagging still exists, so the enthusiasm of the workers is not high, and the effect is not obvious;

[0014] 3. Powerful companies invest hundreds of thousands or even millions of additional equipment, construction facilities and workplaces to process the mud cake after pressure filtration, but additional equipment and site maintenance are added, and follow-up costs are found to be ineffective. Ideally, even if many companies have the money to implement these plans, they find after inspection that the actual effect has not improved, and a series of problems have been brought about, so they reject the implementation and return to the old way

[0021] 3. The filter press is erected very high, and the operation risk is high;

[0022] 4. The mud loading device at the output end is reduced to a mud collection tank in practice, and in many cases, the old method of workers shoveling mud and bagging is still used in the end;

[0023] 5. The cost of the whole scheme is high, far exceeding the price of the filter press itself;

[0024] 6. It requires a large space and high management and maintenance costs

[0033] 1. High construction cost;

[0034] 2. The cost of additional equipment is high;

[0035] 3. The failure frequency of additional equipment is high, and frequent maintenance is required;

[0036] 4. The iron box for collecting mud requires a special hydraulic garbage dump truck, and the freight is high;

[0037] 5. A large space is required;

[0038] 6. It cannot be applied to commonly used tap filter presses;

[0039] 7. When the filter press fails to press tightly, water leakage will cause great pollution to the site;

[0043] 1. High construction cost;

[0044] 2. The site is large and difficult to manage and maintain;

[0045] 3. When the transport vehicle is loaded with mud, under normal circumstances, the mud cake is completely dried in the funnel. At this time, it often falls into the transport vehicle on the first floor from the funnel through the second floor. Odor permeates the entire building, causing great inconvenience to drivers and workers;

[0046] 4. For a long time, it will cause peculiar smell in the working environment and the accumulation of toxic substances, which cannot be removed, causing damage to the health of the operating workers;

[0047] 5. The mud cake often falls out of the car during the process of falling into the car, causing a lot of cleaning work for the workers;

[0048] 6. It cannot be applied to commonly used tap filter presses;

[0049] 7. When the filter press fails to press tightly, water leakage will cause great pollution to the site

[0052] 1. Only suitable for small filter presses;

[0053] 2. It is necessary to manually bag the mud cake, which does not reduce the workload of bagging;

[0054] 3. It only serves to guide the mud cake to one side, avoiding the obstruction of the filter plate to the bagging operation during bagging, and facilitates the bagging of the mud cake, but the cost is high and the cost performance is low;
