Description

Multi-directional rotation rapping electric cleaner

Technical field

The utility model relates to and a kind ofly utilizes high voltage electric field to separate and capture the multi-directional rotation rapping electric cleaner that is suspended in dust in the gas.

Background technology

With dust in high-voltage dc separation and the captured gas, be in an airtight equipment, spaced negative electrode and anode to be installed, apply dc high-voltage to negative electrode, with the anode formation high-voltage dc of ground connection.When dusty gas flows through, the two poles of the earth produce corona discharge, make dust charged, charged dust is under the effect of electric field force, be attracted on negative electrode and the anode to two polar motions, go into the ash bucket discharge by the dust exfoliation that rapping will be adsorbed on the electrode, the gas that flows out electric cleaner is the clean gas after the dedusting.If negative electrode or anode are not provided with vibration body, dust stratification is more and more on the electrode, after being wrapped, negative electrode hinders corona discharge, on the anode behind a large amount of dust stratifications, the dust that motion arrives anode is difficult to electrically charged transfer on the electrode of institute and the formation electric charge gathers, repel and continue the charged dust that motion comes, the corona discharge between negative electrode and anode progressively disappears, and electric cleaner lost efficacy.

At present there are two kinds of top or sidepieces in cathode rapping mechanism, and the top is to utilize electromagnetic hammer or machine hammer, vertically beats the top at negative electrode, and rapping power decays to the process that transmit the bottom gradually from the top, and the rapping power of bottom is little, and the dust that is difficult to gather shakes; Sidepiece shift fork vibration body is got ready and is dropped on the intermediate point, and it is restricted that shift fork will be hammered the angle of having dialled into shape, and rapping power is not enough, and not enough from the rapping power of getting part acquisition far away ready, the dust that gathers is not peeled off.The anode vibration body also has two kinds of top and bottoms, the vertical rapping mode at top and negative electrode top rapping as a same reason, the anode bottom can not get enough rapping power; The bottom rapping then can not get enough rapping power in top.

Summary of the invention

In order to overcome the shortcoming that prior art exists, the purpose of this utility model provides a kind of rapping power abundance, rapping is even, keeps negative electrode and anode cleaning, the rotation vibration body of electric cleaner cathode rapping and the multi-faceted reasonable Arrangement of anode rapping.

The technical scheme that is adopted is: for adapting to multi-faceted layout, negative electrode is the layered framework formula, be that cathode frame is four layers of syllogic, four teeth thorn shape cathode line is installed on the framework, the cathode rapping arrangement of mechanism is at 1/3 place of cathode frame one side and 2/3 place of opposite side, and positive plate is multi-bended with windproof frid, and the upper and lower crossbeam that connects positive plate is again a member of accepting rapping power simultaneously, and the anode vibration body is arranged in the two ends of anode sill and the top of entablature.

Cathode rapping of the present utility model mechanism is that the crank on the rotating shaft connects beater by rotational pin, and when axle rotated to certain position, beater fell, and impacted the rapping anvil.Because cathode frame is a layer-stepping, the rapping anvil of installing on the different levels of the both sides of framework is got the left and right sides that not only is distributed in framework ready, and layering setting in height.The rapping power that each rapping anvil obtains when rapping is delivered in the scope of this layer, and the rapping power that whole cathode line is obtained is sufficient and evenly, the dust that accumulates on the negative electrode is peeled off, and has eliminated because of the decay of rapping power, the hypodynamic defective of certain a part of rapping on the negative electrode.

The anode vibration body is the rotary rapping of dropping hammer, layered arrangement.The two ends of anode sill are equipped with the rapping anvil, and the rapping anvil also is installed on the anode entablature, i.e. rapping divides the left and right sides and arranges up and down.Like this, after vibration body drove, anode obtained to impact rapping power on different aspects and differing heights, and rapping power is evenly distributed on the whole anode, and the dust that accumulates on the anode can all be hit down the cleaning of holding anode.

The rotation vibration body of above-mentioned negative electrode and anode, regulate the weight of tup and the length of hammerhead jib, can obtain different rapping power, adaptability is strong, particularly the dust of the electric cleaner of chemical industry, smelting industry capture is more sticking, and accumulating in needs bigger rapping power just can lay on cathode line and the anode line, and the height of drop of beater is the twice of brachium in the rotation vibration body, add easy to adjustly, can obtain enough rapping power on the electrode.

The specific embodiment

Among Fig. 1,5 is positive plate; 1 is the anode sill, and two ends connect the rapping anvil; 2 is anode lower end vibration body, and each electric field divides the left and right sides to arrange, the rapping power that the rapping anvil obtains during rapping upwards passes to positive plate; 6 is the anode entablature, anode vibration body 7 is installed above it, during this vibration body running, when the rapping anvil on entablature top is subjected to the rapping impact, rapping power is passed to positive plate downwards, anode is when layering rapping up and down, and the rapping that each point obtains on the pole plate decays little and is evenly distributed, and the dust that accumulates in positive plate can in time be stripped down by rapping; 3 is cathode frame, and seamless steel pipe is made, and laterally and vertically is divided into three sections four layers; 4 is the cathode rapping mechanism of lower end, cathode frame left side, the upper end, right side is provided with the cathode rapping mechanism 8 identical with 4, during the cathode rapping mechanical operation of layered arrangement, the rapping power that obtains on the cathode frame of rigidity passes to the cathode line that is connected on the framework, rapping power on the cathode line is even, and the laying dust of each point can all be shaken and take off on the cathode line.

Among Fig. 2, one end of crank 9 is fixed on the rotating shaft 10, and the crank other end is connected by rotational pin 12 with beater 11, position in forwarding figure to, after center of gravity is left the fulcrum of rotational pin 12, beater 11 is made an arc to the right and is fallen, and impacts rapping anvil 13, finishes a rapping, beater 11 is a freely falling body when falling, drop is the brachium of twice, and the size of tup and the length of hammerhead jib can be regulated, and makes the required rapping power of acquisition on negative electrode or the anode.
