Abstract
The utility model provides a drainage device's vacuum system is not shut down in area, including vacuum pump, vacuum buffer tank and two vacuum clarifiers, its characterized in that: the bottom of vacuum buffer tank is through the end of intaking of pipe connection header tank, vacuum buffer tank and header tank are intake and are set up the water intaking valve between the end, set up the pipe connection balanced valve between vacuum buffer tank and vacuum clarifier, the upper portion of header tank is connected to the balanced valve, still be provided with the exhaust -valve between balanced valve and header tank, the play water end (W. E. ) of header tank is provided with the drain valve of comdenstion water in the header tank that is used for draining, the observation hole of being convenient for observe water level is provided with at the top of header tank, increase the vacuum system who does not shut down drainage device, need just not carry out vacuum buffer tank drainage when shutting down the maintenance, the comdenstion water is not assembled too much long -pendingly, avoid too much leading to the fact the compelled phenomenon of shutting down of equipment load increase and vacuum pump because of ponding in the buffer tank, the influence to production is shut down because of ponding to the reduction, increase production efficiency.
Description
Technical field
The utility model belongs to cigarette package field, is specifically related to the vacuum system that drainage means do not shut down by a kind of band.
Background technique
In cigarette package field, Nash hytor provides negative pressure for wraparound workshop wrapping machine, vacuum system is made up of vacuum pump, knock out drum, filter, relevant valve member, pipeline etc., has certain condensed water to belong to normal phenomenon, carry out emptying during each corrective maintenance in knock out drum.During normal work, be negative pressure in knock out drum, general control is at-0.07MPa, and the sewage draining exit arranged at the bottom of tank cannot get rid of inner ponding.Therefore, when vacuum buffer tank drains the water away, vacuum system wants hesitation, will affect wraparound workshop and normally produce.
High-temperature gas during vacuum pump work between inhalation vehicle, (effect of purifier is the negative-pressure gas drawn back in workshop to vacuum cleaner through knock out drum front end, water in purifier, the impurity in filtering gas, avoids entering vacuum pump, cause equipment failure), produce condensed water, when the air simultaneously sucked is by purifier, gas water content increases, produce again time condensation water when entering knock out drum, water of condensation is constantly built up.Along with continuing of producing, too much water is finally caused to enter knock out drum, if the water in knock out drum exceeds the boundary of regulation, and can not discharge in time, the water in knock out drum and subsidiary pipeline will be caused acutely to rock and damage equipment along with negative-pressure air-flow, and pouring in down a chimney with part water enters in vacuum pump, cause vacuum pump load to become large, system cloud gray model vibrations are large waits unsafe factor.
Model utility content
The utility model provides a kind of band not shut down the vacuum system of drainage means according to the deficiencies in the prior art, does not shut down and carries out knock out drum draining, avoids shutting down the impact on producing.
The technical solution of the utility model: the vacuum system of drainage means do not shut down by a kind of band, comprise vacuum pump, vacuum buffer tank and two vacuum cleaners, it is characterized in that: the bottom of vacuum buffer tank connects the feed-water end of header tank by pipeline, between vacuum buffer tank and header tank feed-water end, inlet valve is set, pipeline connecting balanced valve is set between vacuum buffer tank and vacuum cleaner, equilibrium valve connects the top of header tank, also exhaust-valve is provided with between equilibrium valve and header tank, the waterexit end of header tank is provided with the drain valve for condensed water in header tank of draining, the peep hole being convenient to observe water level is provided with at the top of header tank.
Described header tank inside is provided with the level meter being convenient to observe height of water level.
Technique effect of the present utility model: increase the vacuum system of not shutting down drainage means; do not need just to carry out vacuum buffer tank draining when maintenance shut-downs; condensed water can not aggregation too much; avoid because knock out drum internal water accumulation too much causes machine utilization increase and vacuum pump by forced-stopping machine phenomenon; reduce because ponding shutdown is on the impact of producing, enhance productivity.
Accompanying drawing explanation
Fig. 1 is existing vacuum system structural representation;
Fig. 2 is the utility model vacuum system structural representation.
In figure: 1-vacuum pump, 2-vacuum buffer tank, 3-vacuum cleaner, 4-inlet valve, 5-equilibrium valve, 6-exhaust-valve, 7-drain valve, 8-header tank, 9-peep hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As shown in Figure 2, the vacuum system of drainage means do not shut down by a kind of band, comprise vacuum pump 1, vacuum buffer tank 2 and two vacuum cleaners 3, it is characterized in that: the bottom of vacuum buffer tank 2 connects the feed-water end of header tank 8 by pipeline, between vacuum buffer tank 2 and header tank 8 feed-water end, inlet valve 4 is set, pipeline connecting balanced valve 5 is set between vacuum buffer tank 2 and vacuum cleaner 3, equilibrium valve 5 connects the top of header tank 8, exhaust-valve 6 is also provided with between equilibrium valve 5 and header tank 8, the waterexit end of header tank 8 is provided with the drain valve 7 for condensed water in header tank 8 of draining, the peep hole 9 being convenient to observe water level is provided with at the top of header tank 8.
Header tank 8 inside is provided with the level meter being convenient to observe height of water level.
When vacuum buffer tank internal water accumulation is more, inlet valve and equilibrium valve are opened, exhaust-valve and drain shut valve, and the ponding in knock out drum starts to enter in header tank.Height of water level in header tank can be observed by peep hole.This height of water level no longer increases, and illustrates that knock out drum internal water accumulation is emptying, and now only need close inlet valve and equilibrium valve, open exhaust-valve and drain valve, the ponding in header tank is just directly drained from drain valve, completes the drainage procedure of knock out drum ponding.
After equilibrium valve is opened, header tank and vacuum buffer tank form connecting vessels, and both pressure is identical, and therefore after drain valve is opened, knock out drum internal water accumulation can enter in header tank under gravity smoothly, and the equipment that easily achieves does not shut down drain function.
Claims (2)
1. be with the vacuum system of not shutting down drainage means for one kind, comprise vacuum pump (1), vacuum buffer tank (2) and two vacuum cleaners (3), it is characterized in that: the bottom of vacuum buffer tank (2) connects the feed-water end of header tank (8) by pipeline, inlet valve (4) is set between vacuum buffer tank (2) and header tank (8) feed-water end, pipeline connecting balanced valve (5) is set between vacuum buffer tank (2) and vacuum cleaner (3), equilibrium valve (5) connects the top of header tank (8), exhaust-valve (6) is also provided with between equilibrium valve (5) and header tank (8), the waterexit end of header tank (8) is provided with the drain valve (7) for header tank of draining (8) interior condensed water, the peep hole (9) being convenient to observe water level is provided with at the top of header tank (8).
2. the vacuum system of drainage means do not shut down by a kind of band according to claim 1, it is characterized in that: described header tank (8) inside is provided with the level meter being convenient to observe height of water level.
