Abstract
本实用新型涉及一种应用在喷射装置进液口的过滤器，属于液体净化设施技术领域。该过滤器的过滤座上端固定安装过滤体，中部固定安装过滤芯，底部的排污口安装排污阀。过滤芯的上端口与进液口连通，下端口与过滤座底部的排污口连通，过滤座与过滤芯之间的腔室与出液口连通。此外，在过滤体的进液口和出液口之间制有短路通道，该短路通道中装有反冲阀。当反冲阀打开，短路通道开通、过滤芯上端口被关闭时，流入进液口的液体将通过短路通道，进入过滤座与过滤芯之间的腔室，接着反向透过过滤芯，将粘附在过滤表面的细小杂质冲掉，由排污口排出。本实用新型以简单巧妙的结构，实现了过滤芯的自动清洗，操作简便，清洗效果良好。
The utility model relates to a filter applied to a liquid inlet of a spray device, which belongs to the technical field of liquid purification facilities. The upper end of the filter seat of the filter is fixedly installed with a filter body, the middle part is fixedly installed with a filter core, and the bottom drain outlet is equipped with a drain valve. The upper port of the filter core communicates with the liquid inlet, the lower port communicates with the sewage outlet at the bottom of the filter seat, and the chamber between the filter seat and the filter core communicates with the liquid outlet. In addition, a short-circuit channel is formed between the liquid inlet and the liquid outlet of the filter body, and a recoil valve is installed in the short-circuit channel. When the backflush valve is opened, the short-circuit channel is opened, and the upper port of the filter element is closed, the liquid flowing into the liquid inlet will pass through the short-circuit channel, enter the chamber between the filter seat and the filter element, and then pass through the filter element in the reverse direction. The fine impurities adhering to the filter surface are washed away and discharged from the sewage outlet. The utility model realizes the automatic cleaning of the filter element with a simple and ingenious structure, and is easy to operate and has good cleaning effect.
Description
Technical field
The utility model relates to a kind of filter, and especially a kind of filter that is applied in the injection line belongs to fluid purification facility technology field.
Background technology
Filter is one of critical piece in the liquid pipeline system, is installed in the entrance point of injecting-unit usually.Its effect is the particulate contamination in the filtering liquid pipeline system, avoids pipeline blockage, and guarantees the normal use of injecting-unit.
Understand according to the applicant, existing the middle part fixedly mounted filter core through improving the filter with self-cleaning function is shaped on inlet and liquid outlet usually in the filtering base upper end fixed installation of tubular filtering bodies, and the sewage draining exit of bottom is installed blowoff valve.The upper port of crossing filter core is communicated with inlet, and lower port is communicated with the sewage draining exit of filtering base bottom, and filtering base is communicated with liquid outlet with the chamber of crossing between the filter core.When liquid behind the inlet inflow filter, will be through filter element filtering, see through and flow out from liquid outlet after liquid enters chamber.The impurity of being detained in crossing filter core can be opened blowoff valve cleaning discharge.
The filtering surface that above-mentioned existing filter is in use crossed filter core is stopped up by tiny impurity easily, thereby influences the filter efficiency of filter.In order to guarantee the operate as normal of filter, have to often take out filter core and clean or change.
Summary of the invention
The purpose of this utility model is: the shortcoming at above prior art exists proposes a kind of backwashing self-cleaning formula filter that filter core can be finished its cleaning automatically that can need not to take out.
In order to reach above purpose, the filtering base upper end fixed installation of backwashing self-cleaning formula filter of the present utility model is shaped on the filtering bodies of inlet and liquid outlet, and the middle part fixedly mounted filter core, and the sewage draining exit of bottom is installed blowoff valve.The upper port of crossing filter core is communicated with inlet, and lower port is communicated with the sewage draining exit of filtering base bottom, and filtering base is communicated with liquid outlet with the chamber of crossing between the filter core.In addition, between the inlet of filtering bodies and liquid outlet, be shaped on short-channel, and be equipped with at this short-channel and the recoil valve of crossing filter core upper port switching controls.
When recoil valve cuts out, when short-channel is blocked, crosses the upper port of filter core and open filter normal filtration of the present utility model; When recoil valve is opened, short-channel opens, cross the filter core upper port when being closed, external valve closing, the blowoff valve of liquid outlet opened, the liquid that flows into inlet will pass through short-channel, enter the chamber between filtering base and the mistake filter core, then oppositely saw through filter core, the fine impurities that sticks to filtering surface was washed out, discharged by sewage draining exit.
Obviously, the utility model has realized crossing the automatic cleaning of filter core with structure simply cleverly, and easy and simple to handle, and cleaning performance is good.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1---Fig. 3 is respectively duty, cleaning state and the anti-view of cleaning of an embodiment of the utility model.
The specific embodiment
Embodiment one
The backwashing self-cleaning formula filter of present embodiment as shown in Figure 1, in filtering base 1 upper end of tubular by being threaded, fixed installation is shaped on the filtering bodies 2 of horizontal inlet 2-1 and liquid outlet 2-1, middle part fixed installation tubular filter core 3, and the sewage draining exit 1-1 of bottom installs blowoff valve 4.The upper port of crossing filter core 3 is communicated with inlet 2-1, and lower port is communicated with the sewage draining exit 1-1 of filtering base 1 bottom.Filtering base 1 is communicated with liquid outlet 2-2 with the tubular chambers 1-2 that crosses between the filter core 2.Between the inlet 2-1 of filtering bodies 2 and liquid outlet 2-2, be shaped on short-channel 2-3, recoil valve 5 is equipped with in the upper end of filtering bodies 2, and the middle part of this recoil valve 5 and bottom are fixed with control short-channel 2-3 respectively and cross the middle valve gap 5-1 and the bottom flange 5-2 of filter core 3 upper port break-makes.
When as shown in Figure 1, recoil valve (5) is in upper, short-channel (2-3) by in valve gap (5-1) blocking-up, blowoff valve (4) crosses the upper port of filter core (3) and opens when cutting out, the filter of present embodiment is in running order, finishes normal filtration work.
When as shown in Figure 2, recoil valve (5) still is in upper, and blowoff valve (4) is when opening, and the filter of present embodiment is in the cleaning state, and the liquid that inlet (2-1) flows into will be crossed in the filter core (3) filter impurity down by blowoff valve (4) discharge.
When as shown in Figure 3, recoil valve (5) is in the next, short-channel (2-3) opens, cross filter core (3) upper port by bottom flange (5-2) when closing, the external valve closing of liquid outlet (2-2), the filter of present embodiment is in the backwash state, blowoff valve (4) is opened, the liquid that flows into inlet (2-1) will be by short-channel (2-3), enter the chamber between filtering base (1) and the mistake filter core (3), then oppositely saw through filter core (3), the fine impurities that sticks to filtering surface is washed out, discharged by blowoff valve (4).
This shows that the backwashing self-cleaning formula filter of present embodiment can be realized the automatic cleaning of filter core, thereby keep filter to be in good working order all the time, its good manufacturability is used easy and simple to handle.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
