Description

A kind of follow-on Raymond machine

Technical field:

The utility model is specifically related to a kind of follow-on Raymond machine.

Background technology:

Raymond machine (Raymond Mill) is claimed Raymond mill again, belongs to Suspension roller disk fixed disc mill, is the fine grinding equipment of medium rotating speed.It is widely used in hardness such as grinding coal, nonmetallic ore, glass, pottery, cement, gypsum, agricultural chemicals and chemical fertilizer at Mohs below seven grades, and humidity is at the various non-inflammable and explosive mineral products material below 6%.Raymond machine finished product granularity can be regulated in 0.125～0.024 millimeter (being equivalent to 120 orders～325 orders) scope by demands of different.

As shown in Figure 1; Raymond machine of the prior art covers main frame 11, analytical engine, cyclone separator 12, air blast 14, sack cleaner 13 and lingering remnants of past customs machine 15 by thunder to be formed, and thunder covers main frame and links to each other with cyclone separator through blast pipe, and cyclone separator links to each other with air blast through the backflow airduct again; Air blast covers main frame through circulation airduct and thunder again and links to each other; On the circulation airduct, also be connected with lingering remnants of past customs pipe, the other end of lingering remnants of past customs pipe links to each other with sack cleaner, and sack cleaner links to each other with lingering remnants of past customs machine through discharge pipe again.Its main running is following: material is sent into thunder illiteracy main frame and is ground; Main frame drives central shaft through transmission device and rotates; The upper end of central shaft is connecting main parts size plum blossom frame one by one; Burnisher apparatus is housed on the plum blossom frame forms a moving fulcrum, not only round the central shaft revolution, grinding roller itself is because of the friction rotation simultaneously for it.Plum blossom frame lower end is equipped with its position of spade blade device and is just in time staggered with grinding roller; Perching knife is thrown to the material of sending into thunder illiteracy main frame between grinding roller and the bull ring in rotation process; Form a padding layer; Under centrifugal force that when grinding roller revolves round the sun, is produced and the time rotational pressure to the bull ring generation, material is promptly pulverized gradually.60 blades are housed on the blade rotating disk of analytical engine, rotate through electromagnetic adjustable speed motor and belt transmission.Because the electromagnetic adjustable speed motor rotating speed can be regulated by technological requirement, so the speed of blade rotating disk also can correspondingly be regulated.Obtain very thin finished product granularity if ask, must improve the blade speed of gyration so, blade and powder contact rate is increased, the underproof material of more fineness is thrown to the mill shell wall by blade, lose centrifugal force after, reface owing to the gravity effect drops to main frame.The material that fineness is qualified is taken out of by distinguished and admirable, imports cyclone separator through blast pipe, carries out separating of wind and material, and production capacity decreases.Otherwise, obtain thicker finished product granularity, will reduce the blade speed of gyration, blade and material contact rate are reduced, production capacity increases thereupon.Material gets into the cyclone separator that rewinding is used from tangential direction, because air-flow carries out the high speed rotation, in rotary course, produces very big centrifugal force; Most powder is got rid of to wall; Powder is run into the gas wall, loses speed and falls into along wall, separates with gas; Discharge through the flour extraction pipe of star-like discharger again, obtain finished product.The air-flow of rotation is drawn close to the center with the contraction of cone, and air-flow reaches the awl end, just begins rotation and rises; Form general spiral motion from bottom to top, discharge, suck air blast through the backflow airduct again by the cyclone separator top exit; By air blast gas being fed thunder then covers in the main frame; So just formed a circulatory system, material is constantly pulverized, and constantly by carried away by air movement.Because whole air path system moves under negative pressure state; And the grinding machine outside is in barotropic state; So star-like discharger is housed at the cyclone separator lower part outlet; Pin the air-flow of positive negative pressure and isolate, star-like discharger or star-like discharger are poorly sealed will to cause not powder delivery or powder delivery little as not adorning, thereby influences production capacity.But certain moisture is arranged in because of the grinding charge material in that Raymond mill mill is indoor, give birth to heat during grinding, the aqueous vapor evaporation; And each pipe joint imprecision of complete machine; Ambient atmos is inhaled into, and circulation air pressure is increased, and works under negative pressure state for guaranteeing grinding machine; The throughput that is increased enters sack cleaner through lingering remnants of past customs pipe, is cleaned after lingering remnants of past customs machine enters atmosphere.

There is following defective in above-mentioned Raymond machine:

(1) will guarantee the normal operation of cyclone separator, the wind speed control of the main air road circulatory system must meet the requirement of cyclone separator, can not be too high, otherwise cyclonic separation thoroughly will not cause whole air path system solid content first mate to increase, thus increase system loading.

(2) because the gas solid separation of the main air road circulatory system is not thorough, part has been ground qualified material and has been sent into Raymond machine once more through air blast, directly causes the heavy wear of blower wheel and the production capacity of Raymond machine to reduce, and pipeline is prone to stop up.

(3) lingering remnants of past customs pipe leading portion is in barotropic state often, can cause to dust, and influences the work on the spot environment.

Summary of the invention:

The purpose of the utility model provides a kind of system and operates steadily, and solid content is low in the circulatory system of main air road, is prone to block up thereby solved pipeline, and blower wheel dust easy to wear and on-the-spot is big, problems such as operating environment difference, follow-on Raymond machine of raising usefulness.

The utility model is achieved through following technical scheme:

Follow-on Raymond machine of the utility model; Comprise that thunder covers main frame, analytical engine, cyclone separator, sack cleaner and air blast, it is characterized in that described thunder covers main frame and links to each other with cyclone separator through blast pipe; Cyclone separator links to each other with sack cleaner through the first backflow airduct again; Sack cleaner links to each other with air blast through the second backflow airduct again, and air blast links to each other through covering main frame through circulation airduct and thunder again, on the circulation airduct, also is connected with and lingering remnants of past customs pipe.

The production capacity of Raymond machine is closely related with the gas solid separation ability in the circulatory system of main air road, and the utility model gets into thunder through the air blast circulation again through the gas after the dedusting and covers in the main frame through connecting sack cleaner at the back at cyclone separator; Like this, the main air road circulatory system leans on cyclone separator and sack cleaner to carry out gas solid separation, thereby makes gas solid separation more thorough; Can satisfy the gas solid separation amount fully, can not influence the wind speed of circulation wind path simultaneously again, through the gas after cyclone separator and the sack cleaner processing; Dustiness significantly reduces; Wearing and tearing to blower wheel obviously reduce, and are difficult for blocking pipeline, and the lingering remnants of past customs dustiness of lingering remnants of past customs pipe is low; Site environment does not have obvious dust, can also improve usefulness greatly.
