Positive progressive effect of the present utility model is: the utility model locomotive by change drying tower internal structure, is set up centrifugal filter and pressure controller with double tower air adsorption dehumifier.Satisfy under use air-treatment amount and the pressure leak source prerequisite at itself, guarantee that the drier volume is little, energy consumption is low, can manage, monitor the normal operation of drier.
Description of drawings
Fig. 1 is the structural representation of existing adsorption dehumifier.
Fig. 2 is the structural representation of the utility model one embodiment.
The specific embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 2, locomotive of the present utility model comprises drying tower 21 with double tower air adsorption dehumifier, overflow valve 22, double check valve 23, drain valve 24, the control drying tower replaces the magnetic valve 25 of usefulness, silencer 26, guiding control valve 27, pressure sensor 28 and regeneration nozzle 29, drying tower 21 comprises adsorbing medium 201 and centrifugal oil strain separator 202, centrifugal oil strain separator 202 is positioned at the bottom of drying tower 21, the quantity of the quantity of drying tower 21 and drain valve 24 all is two, each drain valve 24 connects with the humid air air inlet of a corresponding drying tower 21, the magnetic valve 25 that the control drying tower replaces usefulness is connected with a drain valve 24, guiding control valve 27 is connected with another drain valve 24, double check valve 23 and regeneration nozzle 29 are connected between two drying towers 21, double check valve 23 and the 29 parallel connections of regeneration nozzle, double check valve 23 also is connected with overflow valve 22, pressure sensor 28 is connected with the humid air air inlet of a drying tower 21, and silencer 26 is connected between two drain valves 24.
When starting air compressor machine, after compression, be higher than room temperature about 15 ℃ to entering vacant air dryer to 20 ℃ compressed air and by drain valve 24, one of them drying tower 21 of flowing through then passes through double check valve 23 again, arrives overflow valve 22 at last.Before the pressure of drying tower reaches setting pressure, overflow valve 22 will keep closed condition.Behind the pressure that reaches setting, will depend on that the control drying tower replaces the position of the magnetic valve 25 of usefulness, that is to say that activation or the magnetic valve that discharges can make one of them or another one drain valve 24 open.When the control drying tower replaces the magnetic valve 25 of usefulness uncharged the time, can open the drain valve 24 on Fig. 2 left side by the compressed air of magnetic valve, simultaneously, the drying tower 21 that compressed air will forward Fig. 2 the right to carries out drying.This blocked operation constantly repeatedly carry out and when one of them drying tower work time another drying tower can regenerate.
In the time of the drying tower 21 of malaria by the right, moisture will be absorbed by the adsorbing medium in this drying tower 201, the dry air at drying tower top will be passed in the air reservoir by double check valve 23 and overflow valve 22. before passing through double check valve 23, the part dry air can enter in the drying tower 21 on the left side by regeneration nozzle 29, from the overhead stream of drying tower to the bottom, so just, the moisture that adsorbing medium in the tower that is dried absorbs can be taken to drain valve 24 dischargings of holding, dry up moisture that is accumulated in this drying tower and the adsorption function that recovers adsorbing medium so that can in next one circulation, from the compressed air of humidity, absorb moisture. depend on the discharge capacity of air compressor machine and the reasons such as size of drier, operation will replace between the drying tower 21 on magnetic valve 25 on the left sides of usefulness and the right by the control drying tower and replace. replace the magnetic valve 25 of usefulness when charged when controlling drying tower, guiding control valve 27 can change its position, compressed air being transported to the air loop of the right drying tower closes, compressed air is passed through from the drying tower on the left side, and the drying tower on the right of the part dry air then enters by regeneration nozzle 29 is discharged the moisture that a last circulation is absorbed.
Locomotive by change drying tower internal structure, adopts the Double layer pipeline design with double tower air adsorption dehumifier.Humid air enters the drying tower shell that adsorbing medium is housed from following piping, and the bottom-up adsorbent bed that flows through, dried air are discharged by drying tower pipe layer from the top down, and this kind structural design greatly reduces the height of drier.Locomotive is finished absorption, regeneration, handoff functionality with double tower air adsorption dehumifier with four transfer valves that two drain valves substitute existing adsorption dehumifier, has saved the connection of components and parts and pipeline, has reduced the pipeline energy consumption, has dwindled the volume of drier.Locomotive adopts a double check valve to replace two one way stop peturn valves of existing adsorption dehumifier with double tower air adsorption dehumifier, and the space has been saved in the connection of having saved components and parts and pipeline, makes the more compact structure of drier.Locomotive is set up the centrifugal oil strain separator of filter oil and water droplet with the bottom of the drying tower in the double tower air adsorption dehumifier, centrifugal oil strain separator can be removed the water droplet that occurs with liquid form in the compressed air as far as possible, locomotive also has function except that water filter and oil removal filter with double tower air adsorption dehumifier, is equivalent to integrated water filter, oil removal filter and drier three devices of removing in one.With respect to whole dryer system, drier need not with remove water filter and oil removal filter and be used, so just saved the connection of two filters and pipeline, reduced the pipeline energy consumption, dwindled the volume of dryer system.Locomotive is provided with pressure sensor with double tower air adsorption dehumifier, whether the operation that can know drier by pressure sensor at any time is normal, to guarantee that drying tower carries out suitable replacing by the cycle of setting, in the course of work that replaces, air pressure in the drying tower air loop of the right can be followed alternate cycles and be changed, do not change in the time limit of setting as pressure, show that then drier does not carry out normally alternately running, thereby fault-signal just can send on the drier controller system, can manage and monitor the normal operation of drier.
Though more than described the specific embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
