Description

Technical Field

[0001] The utility model relates to the field of cement processing equipment, in particular to a cement clinker crushing device with a filtering mechanism. Background Art

[0002] Cement clinker crushing is an important part of cement production. After being crushed, mixed and ground, the clinker is sent to the grinding mill for grinding. In this process, the cement clinker is ground into fine powder for better dispersion and reaction in concrete. The purpose of grinding is to make the material obtain the necessary dispersion and become a product of a certain composition to meet the requirements of various process steps.

[0003] In actual operation, the crushing effect of cement clinker will be affected by many factors, such as feed amount and mill power, powder selection efficiency and circulation load, etc. At the same time, the composition of clinker minerals will also affect its grindability, and then affect the grinding effect. Cement clinker with different diameters requires different crushing equipment. For example, cement clinker below 5 cm can be crushed by a double-roll crusher, which has a better crushing effect.

[0004] Before the cement clinker is crushed, it needs to be screened by size, and the cement clinker that fits the size of the equipment is put into the equipment for crushing. However, the existing filtering mechanism is often set to a relatively single filter plate. The filter plate does not have the function of continuous filtration, and the filtered cement clinker cannot be discharged and keeps accumulating on the filter plate, which is easy to affect the subsequent filtration of cement clinker.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Reference Figure 1-Figure 4 A cement clinker crushing device with a filtering mechanism comprises: a crushing part 1, used for crushing cement clinker; a feeding box 2, installed on the crushing part 1, used for feeding cement clinker; a feeding pipe 3, installed on one side of the feeding box 2, used for conveying cement clinker; a filtering part 201, installed in the feeding box 2, configured to rotate in the feeding box 2, used for filtering cement clinker; a conveying member 202, installed in the filtering part 201, configured to drive the cement clinker that has not been filtered out to discharge from the filtering part 201 when the filtering part 201 rotates.

[0040] The crushing part 1 adopts a double-roll crusher and can also adopt a jaw crusher. The filtering part 201 adopts a stainless steel filter mesh cylinder and can also adopt an aluminum alloy filter cylinder. The filtering part 201 continuously rotates in the feeding box 2 to avoid the accumulation of cement clinker in the filtering part 201. The cement clinker can be continuously filtered. The feeding pipe can also continuously feed the cement clinker and send it into the filtering part 201 for filtration. The filtered cement clinker can also be discharged from the filtering part 201 through the conveying member 202.

[0041] The conveying member 202 adopts stainless steel spiral blades, and may also adopt aluminum alloy spiral blades. When the filter section 201 is rotating, it will drive the spiral blades to rotate together. The design feature of the spiral blades is that they can produce a pushing effect, that is, when they rotate, they will push the material to move along their rotation direction. When the spiral blades rotate in the filter section 201, they will effectively drive the cement clinker in the filter section 201 to move in one direction, which not only helps to continuously convey the cement clinker, but also helps to prevent the clinker from accumulating or clogging in the filter section 201, thereby improving the efficiency and stability of the entire crushing device.

[0042] Reference Figure 1 and Figure 2 The discharge pipe 4 is installed on one side of the loading box 2, and one end of the filter part 201 is arranged in the discharge pipe 4. The discharge pipe 4 is used to transport the cement clinker that has not been filtered out. The discharge pipe 4 can transport the cement clinker discharged from the filter part 201 to a designated area.

[0043] Reference Figure 2 and Figure 3 The loading box 2 includes: a first gear 203, installed on the outer ring of the filter part 201; a second gear 205, installed in the loading box 2 and connected to the first gear 203; a first power source 204, installed on one side of the loading box 2, and a power shaft of the first power source 204 is connected to the second gear 205 for driving the second gear 205 to rotate.

[0044] The first power source 204 adopts a servo motor and can also adopt a stepping motor. The first power source 204 can drive the second gear 205 to rotate, the second gear 205 drives the first gear 203 to rotate, and the first gear 203 can drive the filter part 201 to rotate, thereby realizing continuous driving of the filter part 201, ensuring that the cement clinker can pass through the filter part 201 evenly and continuously, improving the filtering effect, and reducing production interruptions caused by poor filtering.

[0045] Reference Figure 2 and Figure 3A through hole is opened on one side of the feeding box 2, and the filter part 201 is arranged in the through hole. A fixing hole is opened on the other side of the feeding box 2, and the feed pipe 3 is installed in the fixing hole. A connecting hole is opened at one end of the filter part 201, and one end of the feed pipe 3 is arranged in the connecting hole.

[0046] The filter part 201 rotates in the through hole, and the feed pipe 3 is fixedly installed in the fixing hole, so that when the filter part 201 rotates, the feed pipe 3 will not rotate together with the filter part 201 .

[0047] Reference Figure 3 and Figure 4 The feed pipe 3 includes: a feed hopper 301 installed on the feed pipe 3; a conveying rod 303 installed in the feed pipe 3; a second power source 302 installed at one end of the feed pipe 3, and a power shaft of the second power source 302 is connected to one end of the conveying rod 303.

[0048] The second power source 302 uses a stepper motor or a servo motor. The second power source 302 drives the conveying rod 303 to rotate, and also puts the cement clinker into the feed hopper 301. The conveying rod 303 continuously conveys the cement clinker. The continuous movement of the conveying rod 303 also helps to prevent the cement clinker from being blocked or agglomerated during the conveying process.

[0049] Reference Figure 3 The projection of the filter part 201 is circular and has a hollow structure; the projection of the first gear 203 is a ring shape, and the filter part 201 is arranged on the inner ring of the first gear 203. The filter part 201 adopts a circular and hollow structure design, so that the cement clinker can be evenly distributed during the filtering process, thereby improving the filtering effect.

[0050] During use, the first power source 204 can drive the second gear 205 to rotate, the second gear 205 drives the first gear 203 to rotate, and the first gear 203 can drive the filter unit 201 to rotate, thereby realizing continuous driving of the filter unit 201. The filter unit 201 continuously rotates in the feeding box 2, which can avoid the cement clinker from accumulating in the filter unit 201, and can continuously filter the cement clinker. The feeding pipe can also continuously feed the cement clinker and send it into the filter unit 201 for filtration, and the cement clinker that meets the size is sent to the crushing unit 1 for filtration. The cement clinker after crushing and filtering can also be discharged from the filter part 201 through the conveying of the conveying member 202. When the filter part 201 is rotating, it will drive the spiral blades to rotate together. The design feature of the spiral blades is that they can produce a pushing effect, that is, when they rotate, they will push the material to move along the direction of their rotation. When the spiral blades rotate in the filter part 201, they will effectively drive the cement clinker in the filter part 201 to move toward the discharge pipe 4. The discharge pipe 4 can transport the cement clinker discharged from the filter part 201 to a designated area.

[0051] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0052] By adopting the combined design of the filter unit 201 and the conveying member 202, efficient filtration and continuous conveying of cement clinker are achieved. The continuous rotation of the filter unit 201 avoids the accumulation of cement clinker during the filtration process, ensuring the continuity and stability of the filtration.

[0053] The cement clinker is effectively pushed to move in a designated direction by the conveying member 202, which prevents the cement clinker from accumulating and clogging in the filter part 201 and improves the operation efficiency of the entire device.
