Abstract
The utility model discloses a high wear-resiting resistance balancer used for a dedusting pipeline. The high wear-resisting resistance balancer comprises a short pipe (3) connected to the dedusting pipeline. A balancing pipe (1) is arranged in the short pipe (3) and is connected with the inner wall of the short pipe (3) through a connecting plate (2). First wear-resisting layers (5) are arranged on the inner side wall and the outer side wall of the balancing pipe (1) and the two side walls of the connecting pipe (2). A second wear-resisting layer (6) is arranged on the inner wall of the short pipe (3). The high wear-resisting resistance balancer has the advantages of being simple and compact in structure, low in cost, wear resistant, free of adjustment, stable and reliable.
Description
Technical field
The utility model relates generally to the dust pelletizing system field, refers in particular to a kind of resistance balance of the high abrasion for dedusting pipeline device.
Background technique
Dust pelletizing system in the industrial dedusting environmental protection is just towards the future development maximized, and the balance between each branch line of dust pelletizing system also becomes more and more important.In order to make to keep resistance balance between each branch line, traditional way is generally that the regulating equipments such as regulating butterfly valve, push-pull valve and restricting orifice are installed on each branch line.But, being subject to the impact of dust chiseling property of mill and eddy current, these regulating equipments are very easy to lose efficacy because of abrasion, after regulating equipment lost efficacy, system balancing will be lacked of proper care, thereby cause the following problem: 1, part branch road wind speed is too small, easily cause dust deposit, cause line clogging; 2, for maintaining the post concentration of conforming to the standard and requiring, need to increase systematic air flow, cause fan energy consumption to increase; 3, part branch road wind speed is too high, and exhausting point air quantity is excessive, and material is taken away in a large number, and dust pelletizing system is processed and the material of conveying all increases, and causes energy consumption and equipment attrition to increase.
Occurred afterwards a kind ofly mainly by short tube with by connecting plate, being connected in the resistance balance device that the balance tube in short tube forms, at the balance tube inwall, be provided with wear-resistant liner, can prevent that the balance tube internal diameter from changing because of abrasion.But, can between balance tube and short tube, can produce eddy current during this resistance balance device work, make connecting plate, balance tube outer wall and short tube inwall denude very soon, greatly reduce working life.
The model utility content
The technical problems to be solved in the utility model is: the deficiency existed for prior art, provide a kind of simple and compact for structure, with low cost, wear-resistant, without debugging, the reliable and stable resistance balance of the high abrasion for dedusting pipeline device.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of resistance balance of the high abrasion for dedusting pipeline device, comprise the short tube be connected in the dedusting pipeline, be provided with balance tube in described short tube, described balance tube is connected with the short tube inwall by connecting plate, and the inside and outside two side of described balance tube and the two side of connecting plate are equipped with the first wearing layer.
As further improvement of the utility model:
Described short tube inwall is provided with the second wearing layer, and described the second wearing layer extends to the two ends of short tube from the joint of short tube inwall and connecting plate.
Described balance tube and short tube are coaxially arranged.
Described connecting plate is ring.
The two ends of described short tube are provided with the flange for being connected with the dedusting pipeline.
Compared with prior art, the utility model has the advantage of: the resistance balance of the high abrasion for dedusting pipeline device of the present utility model, simple and compact for structure, with low cost, the internal diameter of balance tube can be determined according to dust pelletizing system resistance balance calculation result, without field adjustable; The balance tube inwall is provided with the first wearing layer, and its internal diameter can be because abrasion changes, the operation steady in a long-term of assurance system; Balance tube outer wall and connecting plate two side are provided with the first wearing layer, the short tube inwall is provided with the second wearing layer, can avoid being abraded because vortes interference causes balance tube, connecting plate and short tube, thereby increase the service life.

Fig. 2 is A-A cross section structure schematic diagram in Fig. 1.
Marginal data: 1, balance tube; 2, connecting plate; 3, short tube; 4, flange; 5, the first wearing layer; 6, the second wearing layer.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, high abrasion for dedusting pipeline resistance balance device of the present utility model, comprise the short tube 3 be connected in the dedusting pipeline, be provided with a balance tube 1 coaxial with short tube 3 in short tube 3, in the present embodiment, short tube 3 and balance tube 1 are pipe, balance tube 1 is connected with short tube 3 inwalls by connecting plate 2, and connecting plate 2 is ring.The inside and outside two side of balance tube 1 and the two side of connecting plate 2 are equipped with the first wearing layer 5, wear resistance is good, both can avoid balance tube 1 internal diameter to change because of abrasion, the operation steady in a long-term of assurance system, can avoid again being abraded because vortes interference causes balance tube 1 and connecting plate 2, increase the service life.After being connected in the dedusting pipeline by resistance balance device of the present utility model, the air-flow in the dedusting pipeline passes through while passing through the resistance balance device from balance tube 1, thereby realizes the resistance balance between each dedusting pipeline.
In the present embodiment, short tube 3 inwalls are provided with the second wearing layer 6, the second wearing layers 6 and extend to the two ends of short tube 3 from the joint of short tube 3 inwalls and connecting plate 2.Because this place also is subject to vortes interference, therefore the second wearing layer 6 is set at this place, can improve the wear resistance of short tube 3, extend its working life.The first wearing layer 5 and the second wearing layer 6 can be one-body molded, but also split production; The first wearing layer 5, the second wearing layer 6 can be the high-abrasive material (as wear-resistant ceramic, wearable silicon nitride coating etc.) of attaching.
In the present embodiment, the two ends of short tube 3 are provided with the flange 4 for being connected with the dedusting pipeline.
In other embodiments, balance tube 1 and short tube 3 also can adopt rectangle or other sectional shapes, also should belong to protection domain of the present utility model.
Be only below preferred implementation of the present utility model, protection domain of the present utility model also not only is confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, the some improvements and modifications not breaking away under the utility model principle prerequisite, should be considered as protection domain of the present utility model.
