Description

Technical Field

[0001] This utility model specifically relates to an anti-blocking rotary airlock valve. Background Technology

[0002] One method for treating household waste and waste textile strips is incineration. Incineration equipment requires a feed chute at the furnace inlet. However, since the materials being transported are easily entangled, such as household waste and waste textile strips, traditional rotary valves are prone to clogging. Based on the characteristics of household waste and waste textile strips, this utility model is proposed to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide an anti-clogging rotary airlock valve.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A clog-proof rotary airlock valve includes a housing with an impeller inside. One end of the housing has a feed inlet, and the other end has a discharge outlet. The feed inlet and discharge outlet form a feed channel within the housing. The impeller is located in the feed channel. The vertical center line of the feed inlet is not on the same straight line as the vertical center line of the impeller, and the vertical center line of the feed inlet deviates from the vertical center line of the impeller. The feed inlet and discharge outlet are staggered.

[0006] Preferably, the impeller is connected to the output shaft of the geared motor.

[0007] Preferably, the vertical centerline of the discharge port is on the other side of the vertical centerline of the impeller.

[0008] Furthermore, a counterweight self-adjusting door is provided inside the housing.

[0009] Preferably, a counterweight block is provided on the outer side of the self-adjusting counterweight door.

[0010] Furthermore, the impeller is a star-shaped impeller.

[0011] Preferably, the impeller is an ultra-large diameter impeller.

[0012] Furthermore, the impeller has a rotation diameter of 1180 mm.

[0013] Beneficial technical effects:

[0014] This utility model uses staggered inlet and outlet ports and a counterweight self-adjusting gate. The eccentric design of the inlet and outlet ports allows the material to fall fully onto the right side of the housing and enter the counterweight self-adjusting gate, thus effectively preventing material blockage.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Reference Figure 1-2 A clog-resistant rotary airlock valve includes a housing 1, within which an impeller 2 is housed. The impeller 2 is connected to the output shaft of a reduction motor 3. One end of the housing 1 has a feed inlet 5, and the other end has a discharge outlet 6. The feed inlet 5 and discharge outlet 6 form a feed channel within the housing 1. The impeller 2 is positioned within this feed channel. The vertical centerline of the feed inlet 5 is to one side of the vertical centerline of the impeller 2; that is, the vertical centerline of the feed inlet 5 and the vertical centerline of the impeller 2 are not collinear, and the vertical centerline of the feed inlet 5 deviates from the vertical centerline of the impeller 2. The feed inlet 5 and discharge outlet 6 are staggered. This eccentric design of the feed inlet 5 and discharge outlet 6 allows material to fall fully onto the right side of the housing 1 and enter the counterweight adjustment gate, effectively preventing material blockage.

[0022] The vertical centerline of the discharge port 6 is on the other side of the vertical centerline of the impeller 2, that is, the vertical centerline of the discharge port 6 and the vertical centerline of the impeller 2 are not on the same straight line, and the vertical centerline of the discharge port 6 deviates from the vertical centerline of the impeller 2.

[0023] The housing 1 is equipped with a counterweight self-adjusting door 4. This door prevents material from getting stuck on the impeller 2. When material falls onto the blades of the impeller 2, the rotation of the impeller 2 causes the material to fall into the discharge port 6. When the impeller 2 gets stuck, more and more material accumulates on it, pressing against the gap between the impeller 2 and the counterweight self-adjusting door 4. The door then swings outward, resolving the jamming problem. The impeller 2 continues to rotate, and the stuck material falls into the discharge port 6. The counterweight self-adjusting door 4 then resets under gravity. A counterweight block 7 is located on the outside of the counterweight self-adjusting door 4. The weight of the counterweight block 7 can be adjusted according to actual counterweight requirements.

[0024] The impeller 2 is a star-shaped impeller. The impeller 2 uses an extra-large diameter impeller, which ensures a sufficiently long outer circumference, effectively preventing excessively long fabric strips from getting tangled on the impeller. The rotational diameter of the impeller 2 in the anti-clogging rotary airlock valve is 1180mm. The rotational speed of the star-shaped impeller is 20–30 rpm. The motor power of the geared motor 3 connected to the impeller 2 is 15–22 kW; the conveying capacity of the anti-clogging rotary airlock valve is 20–50 T / H.

[0025] The self-adjusting counterweight gate 4 is designed with anti-blocking and anti-jamming features. When material enters the impeller 2, the self-adjusting counterweight gate 4 rotates through the impeller 2 to the position of the self-adjusting counterweight gate 4. The self-adjusting counterweight gate 4 will automatically adjust the gap between the self-adjusting counterweight gate 4 and the impeller 2 according to the amount of material, thus preventing blockage and jamming.

[0026] This utility model of anti-clogging rotary airlock valve is mainly used on the furnace inlet feed chute to prevent backfire caused by positive pressure in the boiler.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
