Abstract
The utility model discloses a water desalting device for a granulator. The device comprises a water desalting header pipe and a water inlet pipe, wherein the water desalting header pipe is connected with two branches which are connected in parallel; filters are arranged on the two branches; the two branches are gathered and are connected with the water inlet pipe through a pressure transmitter; and the water inlet pipe is respectively connected with a spraying water pipe, an overflow water pipe and a conveying water pipe in the granulator. Two parallel branches with filters are used, one branch serves as later use, and when one filter is blocked, only the other branch is required to be started, the granulator is not required to be stopped, and melt waste emission is avoided.
Description
Technical field
The utility model relates to pellet device, and the desalted water device of Pet Production Line with the pelleter of online changeable desalted water filter particularly is provided.
Background technology
In polyester production process, the pelletizing process is an important step in producing, and the effect of pelleter is that the PET Cast Strip is cut into particle, and namely PET is transported to the end of extruded band of pelletizing operation by fondant filter through the melt Conveying pump.The PET melt is cast band through end of extruded band, and under the effect of overflow water and shower water, the band that end of extruded band is cast is sent into the feeding roller of pelleter, and feeding roller is sent into band the cutting chamber of pelleter, is cut into particle at the cutting chamber band by stationary knife and moving knife.Pelleter mainly comprises deflector, cutting head, body and support, water device etc.And the water device of pelleter is desalted water to be delivered to the pelleter place after Pressure gauge 2, filter 3 filters by a water pipe 1; as shown in Figure 1; three strands of moisture are overflow water, shower water, conveying water, and three strands of each own stop valves of water, flow indicator alarms are controlled separately.The overflow water of pelleter and the low newspaper of conveying discharge can cause the pelleter waste discharge, and the low newspaper of shower water can waste discharge.Whether pellet device whether produce stable by stable directly impact.Whether size, the shape of section size be regular, the even spinnability that directly affects long filament.The desalted water that uses at pellet device so is the vital ring of pellet device; because desalted water plays the effect of conveying and spraying cooling melt; if the desalted water instability of flow will cause the pelleter waste discharge, even put on a suit of armour; be that melt piles with cutting chamber and causes a large amount of melt waste discharges; this just may damage pelleter, also might because pelleter can't afford to drive, cause the load down processing; will have a strong impact on production run, cause large economic loss.Existing pelleter desalted water device only has a desalted water transfer pipeline, in case the plugged filter on pipeline, the pelleter cleaning of can only stopping causes the melt waste discharge.Therefore, need a kind of new pelleter desalted water device, reduce pelleter and shut down number of times.
The utility model content
Problem to be solved in the utility model is to provide a kind of desalted water device of pelleter, overcomes the above-mentioned problems in the prior art.
The desalted water device of a kind of pelleter of the utility model; comprise desalted water house steward and water inlet pipe; described desalted water house steward is connected with two branch roads of parallel connection; be equipped with filter on described two branch roads; described two branch roads converge by being connected with described water inlet pipe after a pressure transmitter, and described water inlet pipe is connected respectively with spray header, overflow pipe and conveying water pipe in pelleter.The utility model adopts two branch roads with filter in parallel, and wherein one after a filter is blocked, as long as start another branch road, and need not to cut off pelleter as standby, avoids causing the melt waste discharge.
The utility model also is provided with the first ball valve and the second ball valve in the both sides of described the above filter of parallel branch.
Filter described in the utility model is basket filter.
Desalted water house steward described in the utility model is provided with the 3rd ball valve and Pressure gauge.
By above technical scheme, the desalted water device of a kind of pelleter of the present utility model has following advantage:
1, it can react spray header, overflow pipe and the conveying water pipe pressure before that enters in pelleter in good time.The cleaning in case plugged filter in existing desalted water device, pelleter can only be stopped causes the melt waste discharge; in case and plugged filter in desalted water device of the present utility model; just can switch to another filter, pelleter need not stop, and avoids causing the melt waste discharge.
2, the utility model has increased the processing time, avoids because three bursts of discharge deficiencies cause waste discharge, so by after technological transformation, reduce the waste discharge number of times, and reduced the waste discharge amount, has reduced the waste material amount of melt per ton.
3, above-mentioned filter is basket filter, by having increased basket filter, and is two and forms the using and the reserved, has extended the cycle of operation of pelleter.
Description of drawings
Fig. 1 is the structure chart of pelleter desalted water device in prior art.
Fig. 2 is the structure chart of a kind of pelleter desalted water of the utility model device.
In figure, 1, the desalted water house steward; 2, Pressure gauge; 3, filter; 4, pressure transmitter; 5, spray header;
6, overflow pipe; 7, carry water pipe; 8, filter; 9, the first ball valves; 10, the second ball valves;
11, the three ball valves; 12, pelleter.
The specific embodiment
As shown in Figure 2, the desalted water device of a kind of pelleter of the present utility model comprises desalted water house steward 1, water inlet pipe, and desalted water house steward 1 is connected with two branch roads of parallel connection, article two, branch road converges by being connected with water inlet pipe after a pressure transmitter 4, is equipped with filter 3,8 on two branch roads; Water inlet pipe respectively with pelleter 12 in spray header 5, overflow pipe 6 and carry water pipe 7 to be connected.The utility model adopts two branch roads with filter in parallel, and wherein one after a filter is blocked, as long as start another branch road, and need not to cut off pelleter as standby, avoids causing the melt waste discharge.
On above-mentioned branch road, the both sides of filter 3 or filter 8 also are provided with the first ball valve 9 and the second ball valve 10.Above-mentioned filter 3,8 is basket filter.Desalted water house steward 1 is provided with the 3rd ball valve 11 and Pressure gauge 2, detects the pressure of desalted water.
for example: the route of walking when normal operation is that desalted water house steward 1 enters spray header 5 in pelleter by pressure transmitter 4 after Pressure gauge 2 enters filter 3, overflow pipe 6 and conveying water pipe 7, when at this moment, control finds that the pressure of pressure transmitter 4 is down to low newspaper value 5.7Bar by normal 5.99Bar, this just illustrates that filter 3 has stopped up, to quickly switch, middle control person can notify the Field Force to switch to the another one branch road immediately, and desalted water house steward 1 enters spray header 5 in pelleter by pressure transmitter 4 after Pressure gauge 2 enters filter 8, overflow pipe 6 and conveying water pipe 7, whether the pressure of noting pressure transmitter 4 during switching rises, the flow that so just can guarantee three strands of water normally moves.If there is no an other branch road, if the pressure of pressure transmitter 4 continue to reduce, when overflow water with when carrying the flow of water to reach low newspaper value, pelleter will chain automatic waste discharge, brings economic loss to company.Just because of pelleter desalted water device of the present utility model has been arranged, it has improved operating efficiency, has guaranteed the stable of product quality.
