Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to an air inlet equalizer for a dust collector. Background Art

[0002] The dust collector uses filter bags and other filtering structures to filter the dust particles in the passing dust-laden gas. The filtering structures are densely arranged in the dust chamber, and the air inlet of the dust collector is set at a position lower than the filtering structure. After the dust-laden gas enters the dust chamber from the air inlet, the heavy dust particles therein settle under the action of their own weight, and the light dust particles are filtered by the air flow to the filtering structure. Since the air flow in the dust collector is generally upward, the dust particles in the dust-laden gas sucked in from the air inlet will directly impact the filtering structure, which will cause the filtering structure to be easily damaged. For this reason, if Figure 8 As shown, currently, a baffle is often added to the air inlet to redirect the airflow downward before flowing upward, with the goal of reducing the direct impact of the airflow on the filter structure. However, in actual use, it has been found that the airflow after being deflected by the baffle is concentrated, that is, it only flows to a portion of the filter structure. The filtration pressure in this part of the filter structure is relatively high. Moreover, due to the significant impact, this part of the filter structure will also damage much faster than the rest of the filter structure, resulting in a high frequency of downtime for maintenance. Therefore, it is necessary to provide a method to alleviate this problem. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention is further described below with reference to the accompanying drawings and examples. In the detailed description that follows, certain exemplary embodiments of the present invention are described by way of illustration only. It goes without saying that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims.

[0022] like Figures 1 to 5 As shown, the dust collector inlet flow equalizer is installed at the air inlet 12 of the dust collector 1. Conventionally, the air inlet 12 is located on the wall of the dust chamber 11 of the dust collector 1 and is arranged below the filter structure 2. This embodiment includes two supports 3 fixedly installed on the inner wall of the dust collector 1 and located on both sides of the air inlet 12. Of course, the supports 3 are installed on the wall of the dust chamber 11. The supports 3 are the carriers of the diversion structure and can be plate-type structures or welded frame structures, without limitation.

[0023] Several diverter plates 4, positioned facing the air inlet 12, are fixedly mounted between the two support bodies 3. As long as the airflow from the air inlet 12 strikes the surface of the diverter plates 4, the diverter plates 4 are considered facing the air inlet 12. The diverter plates 4 are arranged in descending order away from the air inlet 12, forming a stepped arrangement. Diverter channels 41 are formed between adjacent diverter plates 4, as well as between the diverter plates 4 near the air inlet 12 and the dust collector 1. Several side flow ports 31 are provided on the support body 3.

[0024] After the dust-laden airflow is sucked in from the air inlet 12, it impacts the various diverter plates 4 at different heights, that is, the airflow is divided into multiple streams by means of the multiple diverter plates 4 arranged in a stepped manner. Each separated airflow is further diverted in four directions, namely, upward, downward, left and right, along the diversion channel 41 and the side flow port 31. The airflow diverted downward is finally turned back and then flows upward in the dust chamber 11. Relying on the above-mentioned structural principle, the dust-laden airflow at the air inlet 12 is divided into dispersed airflows that go directly upward, to the left, to the right, and upward after turning back after passing through this embodiment. The uniformity of the airflow is improved, which is beneficial to balancing the filtering pressure of the filter structure 2. Moreover, the dispersed airflow has less impact on the filter structure 2, and the eccentricity phenomenon is significantly reduced. The filter structure 2 is not prone to individual premature damage, and the single-use time is extended, which is beneficial to reducing the frequency of downtime maintenance.

[0025] Preferably, the diverter plate 4 includes a wind shielding section 42 and a wind limiting section 43 located above the wind shielding section 42. The wind limiting section 43 is disposed obliquely upward in a direction close to the air inlet 12. Since the airflow entering the dust chamber 11 tends to flow directly upward, the provision of the wind limiting section 43 reduces the amount of airflow flowing upward from the diverter channel 41. This not only further promotes airflow uniformity, but also reduces the impact force of the directly upward airflow, further alleviating the phenomenon of biased impact.

[0026] Preferably, a diversion angle adjustment mechanism 5 is provided between the diverter plate 4 and the two support bodies 3, and the diverter angle adjustment mechanism 5 makes the diverter plate 4 adjustable in angle, so as to adapt to the particle size of the dust-laden airflow or the airflow velocity, etc., and perform adaptive adjustment. For example, when the number of large particles in the dust increases or the airflow velocity increases, the diverter plate 4 is adjusted to an inclined posture with the lower end away from the air inlet 12, such as Figure 3 As shown, at this time, the diverter plate 4 itself forms a posture that mainly guides the flow downward, and at the same time, the upward channel area of ​​the diverter channel 41 is reduced. The airflow at each diverter plate 4 mainly flows downward and then turns back upward, thereby promoting the rapid sedimentation of large particles and further reducing the direct upward airflow strength at each diverter plate 4, while ensuring the uniformity of the airflow, reducing the impact damage to the filter structure 2.

[0027] The diversion angle adjustment mechanism 5 described in this embodiment includes a rotating shaft 51 installed between the diverter plate 4 and the two support bodies 3, and the diverter plate 4 is rotatably installed on the two support bodies 3 around the rotating shaft 51; the rotating shaft 51 can be a pin shaft or bolt that is integrally installed between the diverter plate 4 and the two support bodies 3, or it can be a pin shaft or bolt that is separately arranged between the diverter plate 4 and the two support bodies 3 but is coaxial. The effects are the same and are not limited here.

[0028] The support body 3 is provided with a diverter angle adjustment arc hole 52, which is arranged concentrically with the rotating shaft 51. The diverter plate 4 is provided with a diverter angle connection hole 53, which is arranged on the same circumference as the diverter angle adjustment arc hole 52. Of course, the same circumference here refers to the circumference of the rotation around the rotating shaft 51. A diverter angle fixing bolt is installed between the diverter angle connection hole 53 and the diverter angle adjustment arc hole 52. When the diverter angle fixing bolt is loosened, the diverter plate 4 is free to rotate. After rotating to the desired angle, the diverter angle fixing bolt is re-tightened to complete the angle adjustment.

[0029] In this embodiment, the plurality of diverter plates 4 arranged in a stepped pattern create a dispersed airflow, improving airflow uniformity, facilitating balanced filtration pressure within the filter structure 2, and reducing maintenance downtime. Furthermore, the diverter plates 4 are adjustable in angle, allowing for adaptability to varying dust-laden airflows and flow rates, providing greater flexibility and a wider range of applications.

[0030] Example 2: Figure 6 and Figure 7 As shown, the difference between this embodiment and the first embodiment mainly lies in that: the wind-limiting section 43 is swingably mounted on the upper end of the wind-shielding section 42, and a wind-limiting angle adjustment mechanism 6 is provided between the wind-limiting section 43 and the wind-shielding section 42. Therefore, on the basis that the diverter plate 4 can be angle-adjusted, the wind-limiting section 43 can be angle-fine-tuned as needed to produce a more uniform airflow. For example, when the number of large particles in the dust particles increases or the airflow velocity increases, the diverter plate 4 is adjusted in the direction away from the air inlet 12 at the lower end, and the amount of air flowing downward and returning at the diverter plate 4 is significantly increased. If the airflow is too large, the amount of air flowing upward is increased by swinging the wind-limiting section 43 upward to alleviate the situation of excessive local airflow, so as to achieve the purpose of achieving better airflow uniformity by coordinating with the angle adjustment of the diverter plate 4.

[0031] The wind-limiting angle adjustment mechanism 6 of this embodiment includes a wind-limiting angle adjustment lug 61 fixedly mounted on the wind-limiting section 43. The wind-limiting angle adjustment lug 61 is provided with a wind-limiting angle adjustment arc hole 62 concentric with the swing axis of the wind-limiting section 43. A wind-limiting angle fixing bolt 63 is mounted on the wind-shielding section 42 and passes through the wind-limiting angle adjustment arc hole 62. When the wind-limiting angle fixing bolt 63 is loosened, the wind-limiting section 43 is free to swing. After swinging to the desired angle, the wind-limiting angle fixing bolt 63 is re-tightened to complete the angle fine-tuning.
