Description

Technical Field

[0001] This utility model relates to the field of filter press material pretreatment equipment, and in particular to a slurry storage mechanism with a filtration system. Background Technology

[0002] Filter presses, as efficient and practical solid-liquid separation equipment, are widely used in solid-liquid separation processes in fields such as coal mines, coal slime, and municipal wastewater. Taking the coal mining industry as an example, coal slime slurry is a byproduct of coal washing and contains a large number of large particulate impurities. When this coal slime slurry containing a high concentration of particulate impurities enters the filter press, a large number of particulate impurities easily deposit in the bends, valves, and narrow parts of the pipes, causing blockages. Once the pipes are blocked, not only will the feed to the filter press be unable to proceed normally, affecting the continuity of the entire production process, but it will also bring great difficulties to subsequent cleaning work, increasing labor costs and equipment maintenance costs.

[0003] In particular, the presence of particulate impurities can lead to uneven feeding. Due to the influence of impurities, the flow rate and volume of the slurry will be inconsistent in different parts during the process of entering the filter chamber. Some areas may be over-fed and clogged, while other areas may be under-fed. This will significantly reduce the filtration efficiency of the filter press, prolong the dewatering time of the coal slime, and thus affect the overall production efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a slurry storage mechanism with a filtration system that is simple in structure, can screen materials before they enter the filter press, and thereby filter out large particulate impurities, ensuring production safety and filtration effect.

[0005] The equipment includes a storage tank, which is the basis for the assembly of this equipment and also the basis for logistics storage;

[0006] The storage tank is equipped with a feed pipe, and a filter unit is installed between the feed pipe and the storage tank.

[0007] The filtration unit includes a support frame mounted on top of the storage tank; a filter is mounted on the support frame.

[0008] Below the filter, inside the storage tank, there is a material diversion pipe.

[0009] The effect achieved is that the material falls onto the filter unit through the feed pipe, is filtered by the filter unit, and large solid particles are separated. The filtered slurry flows into the storage tank through the material diversion pipe, which is how large particles of material are screened.

[0010] The beneficial effects of this utility model are as follows: This utility model solves the problem of large particulate impurities in the feed of filter presses in the prior art, realizing pre-filtration of materials before they enter the filter press; through the setting of this equipment, materials can be filtered before entering the storage tank, thereby ensuring the uniformity of materials, reducing maintenance costs, and improving production efficiency. In particular, this equipment has a simple structure, low cost and maintenance cost, and is easy to maintain. Attached Figure Description

[0015] Reference Figure 1 The present invention provides a slurry storage mechanism with a filtration system, which includes a storage tank 2. The storage tank 2 is the assembly basis of this equipment and also the basis for logistics storage.

[0016] The storage tank 2 is equipped with a feed pipe 1, and a filter unit is installed between the feed pipe 1 and the storage tank 2.

[0017] The filtration unit includes a support 8, which is mounted on top of the storage tank 2; a filter is mounted on the support 8.

[0018] Below the filter, a material diversion pipe 9 is provided inside the storage tank 2.

[0019] Preferably, the storage tank 2 is further provided with a discharge pipe 3 below it.

[0020] The effect achieved is that the material falls onto the filter unit through the feed pipe 1, is filtered by the filter unit, and large solid particles are separated. The filtered slurry flows into the storage tank 2 through the material diversion pipe 9, which is to achieve the screening of large particles.

[0021] In Example 1, the filter unit is movably mounted on top of the storage tank 2, that is, the support 8 is movably mounted on top of the storage tank 2.

[0022] Preferably, the bottom surface of the bracket 8 is integrally connected with an annular assembly that connects to the inlet of the storage tank 2, and is assembled on the top of the storage tank 2 through the nesting of the above-mentioned components with the inlet of the storage tank 2.

[0023] This allows the equipment to be flexibly disassembled to handle different materials, and also facilitates the cleaning and maintenance of the filter unit itself.

[0024] Example 2, the filter is configured as follows:

[0025] Multiple roller frames are provided on the bracket 8, and each roller frame is rotatably equipped with a transmission roller.

[0026] The two ends of the transmission roller are respectively provided with transmission sprockets. At both ends of the multiple transmission rollers, two sets of transmission chains 7 are sleeved on the transmission sprockets. A metal mesh belt 6 is provided on the inner side of the transmission chain 7, and a filter screen 5 is provided between the two metal mesh belts 6.

[0027] Any one of the transmission rollers is connected to the motor 4.

[0028] The effect achieved is that the motor 4 starts the transmission sprocket to rotate, which drives the chain and filter screen 5 to circulate and filter the slurry; large solid particles fall from the end of the machine tail, thus achieving the filtration of large particles.

[0029] Furthermore, the transmission rollers are provided in three ways: two transmission rollers arranged horizontally corresponding to the material diversion pipe 9, and one transmission roller arranged at the tail end of the filter and inclined upward.

[0030] The effect achieved is to increase its drainage or slurry filtration effect, so that the slurry is concentrated and filtered out to the material diversion pipe 9.

[0031] Furthermore, corresponding to the tail end of the filter, a recycling bin is also provided on one side of the storage tank 2.

[0032] This achieves the effect of recycling large particulate materials.

[0033] Furthermore, the filter screen 5 is made of plastic.

[0034] This achieves the effect of facilitating the cleaning and maintenance of filter 5 and enabling low-cost replacement.

[0035] In Example 3, a plurality of support arms 10 are fixedly provided on the outer wall of the material diversion pipe 9, and the support arms 10 are fitted into the inner cavity of the storage tank 2.

[0036] The material diversion pipe is movably installed inside the storage tank 2 and is supported by the support arm 10 to achieve stable assembly.

[0037] The effect achieved is that the equipment can be flexibly removed or assembled, thereby adapting to different materials and its own cleaning and maintenance.

[0038] In Example 4, a collection cover is provided on the material inlet pipe corresponding to the filter, and the collection cover is attached to the bottom of the filter screen 5.

[0039] The "below" mentioned here refers to the lower surface of the belt of a conveyor belt, which is used to achieve the effect of fully collecting the filtered slurry.

[0040] Furthermore, the material diversion pipe 9 is provided with multiple auxiliary pressure relief holes arranged in an array from top to bottom.

[0041] The effect achieved is that when the slurry flows in too fast or the flow rate is too large, the material in the material diversion pipe is guided by the auxiliary pressure relief hole to avoid the material overflowing.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
