Description

Technical Field

[0001] The invention relates to the technical field of electrostatic precipitators, and in particular to an ash hopper for electrostatic precipitators. Background Art

[0002] The electrostatic precipitator body, in addition to the inlet and outlet horn boxes, consists of a shell and an ash hopper in the middle, which are welded into a whole. The rectangular box-type shell contains the anode and cathode systems. The dust removed falls into the ash hopper and is discharged through the sealed ash discharge valve. The ash hopper is an inverted square cone, with a large upper opening and a small lower opening, and the upper opening is connected to the shell. The shell is divided into several electric fields, and the lower ring beams are also divided into several blocks, which are connected to the ash hopper. Along the airflow direction, there is one ash hopper for each electric field. If the ash hopper and the shell are only welded at the ends, the weld will bear the weight of the ash hopper and the ash stored in the ash hopper. Large electrostatic precipitators require the ash hopper to store dust for 8 hours. If the ash hopper is full of ash, the weight of the ash hopper plus the ash will exceed 100t, and the weld will be torn. Even if a rectangular connecting support beam is added between the ring beams, it is still connected and welded by the end faces of the steel plates. The weld will also bear the tensile force and be easily torn. Summary of the invention

[0003] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0027] Example 1, reference Figure 1 to Figure 2 , which is the first embodiment of the present invention, provides an ash hopper 102 for electrostatic precipitator, including a main body mechanism 100, including an electrostatic precipitator housing 101 and an ash hopper 102 arranged at the bottom end of the electrostatic precipitator housing 101; a connecting mechanism 200, including a first connecting piece 201 arranged on the electrostatic precipitator and a second connecting piece 202 arranged on the ash hopper 102; the electrostatic precipitator housing 101 and the ash hopper 102 are connected by the first connecting piece 201 and the second connecting piece 202.

[0028] Specifically, the bottom end of the electrostatic precipitator housing 101 and the end of the ash hopper 102 are welded.

[0029] The first connecting member 201 includes a first connecting rod 201a and a first connecting block 201b arranged on the first connecting rod 201a. The first connecting rod 201a and the first connecting block 201b are integrally formed with the inner wall of the electrostatic precipitator housing 101.

[0030] Furthermore, a plurality of first connecting rods 201a are provided, and the first connecting rods 201a are used to provide supporting force for the first connecting blocks 201b.

[0031] Furthermore, a through hole 201c is opened at the central axis position of the first connecting block 201b, and the cross-sectional area of ​​the end of the through hole 201c away from the second connecting member 202 is larger than that of the end close to the second connecting member 202.

[0032] It should be noted that the connection mechanism 200 is used to strengthen the connection between the electrostatic precipitator housing 101 and the ash hopper 102. The electrostatic precipitator housing 101 is the main structure of the electrostatic precipitator and is used to accommodate the anode and cathode systems in the electrostatic precipitator process, while the ash hopper 102 is located at the bottom of the housing and is used to collect the separated dust. In order to strengthen the connection between the two parts, a connection mechanism 200 is designed, including a first connection piece 201 on the electrostatic precipitator and a second connection piece 202 on the ash hopper 102, which together realize a stable connection between the housing and the ash hopper 102.

[0033] The bottom end of the electrostatic precipitator housing 101 is connected to the end of the ash hopper 102 by welding, providing preliminary fixation. The first connecting member 201 is composed of a first connecting rod 201a and a first connecting block 201b, which are integrally formed with the inner wall of the electrostatic precipitator housing 101 to enhance the strength and integrity of the connection. The first connecting rod 201a is provided with multiple groups to provide support for the first connecting block 201b to ensure the stability of the connection.

[0034] Example 2, reference Figures 1 to 3 This embodiment is different from the first embodiment in that the second connecting member 202 includes a second connecting rod 202a and a second connecting block 202b, and the second connecting rod 202a, the second connecting block 202b and the inner wall of the ash hopper 102 are integrally formed.

[0035] Specifically, a plurality of second connecting rods 202a are provided, and the second connecting rods 202a are used to provide supporting force for the second connecting blocks 202b.

[0036] Furthermore, the end of the second connecting block 202b is fixedly connected to a connecting shaft 202c, and the end of the connecting shaft 202c is fixedly connected to a bearing block 202d.

[0037] It should be noted that the second connecting piece 202 is provided to achieve a stable connection between the electrostatic precipitator housing 101 and the ash hopper 102, and includes a second connecting rod 202a and a second connecting block 202b integrally formed with the inner wall of the ash hopper 102. This integrated structural design enhances the strength and reliability of the connection, and avoids failures that may be caused by welding or additional connecting pieces. The connection shaft 202c at the end of the second connecting block 202b cooperates with the fixedly connected load-bearing block 202d to further enhance the load-bearing capacity of the overall structure, so that the entire ash hopper 102 can bear the weight of the dust and remain stable.

[0038] The rest of the structure is the same as that of Example 1.

[0039] Example 3, reference Figures 1 to 3 This embodiment is different from the above embodiments in that: the load-bearing block 202d includes a connecting plate 202e, a support rod 202f fixedly connected to the end of the connecting plate 202e, and a clamping block fixedly connected to the end of the support rod 202f; the connecting plate 202e, the support rod 202f and the clamping block are integrally formed, and the support rod 202f and the clamping block are provided in multiple groups and the number is the same.

[0040] Specifically, there are gaps between two adjacent groups of support rods 202f and the clamping blocks, the support rods 202f have a certain elasticity, the end of the clamping block away from the support rods 202f is an arc surface, and the cross-section formed by the ends of all support rods 202f and the gaps is circular, the diameter of the circle is larger than the diameter of the connecting plate 202e, and the diameter of the circle is the same as the diameter of the cross-section of the end of the through hole 201c away from the second connecting member 202.

[0041] It should be noted that the support rods 202f and the clamping blocks in the load-bearing block 202d are provided in multiple groups, and the number is the same. Such a layout can provide uniform support force and ensure the stability of the ash hopper 102. There is a gap between two adjacent groups of support rods 202f and clamping blocks, so that the load-bearing block 202d can adapt to different loads and slight deformations.

[0042] The support rods 202f have a certain elasticity, which means that they can deform to a certain extent when bearing weight and then return to their original shape, which helps to absorb and reduce impact and extend the service life of the structure. The end of the clamping block away from the support rod 202f is designed as a curved surface, which helps to provide better adaptability and stability when connecting.

[0043] The cross section formed by the ends of all the support rods 202f and the gaps is a circle, and the diameter of the circle is larger than the diameter of the connecting plate 202e. Such a design can increase the load-bearing area of ​​the load-bearing block 202d and improve the stability of the structure. At the same time, the diameter of the circle is the same as the cross-sectional diameter of the end of the through hole 201c away from the second connecting member 202, ensuring the tightness and stability of the connection.

[0044] The rest of the structure is the same as that of Example 2.

[0045] Operation process: When the bottom end of the electrostatic precipitator shell 101 in the present invention is connected to the end of the ash hopper 102, first move the clamping block at the end of the connecting plate 202e upward along the bottom end of the through hole 201c, that is, one end of the through hole 201c close to the second connecting piece 202. Since the end of the clamping block is an arc surface, the support rod 202f has a certain elasticity and there is a gap between the two adjacent groups of clamping blocks and the support rod 202f. Therefore, when the clamping block enters the bottom end of the through hole 201c, there is almost no gap between the two groups of clamping blocks and the support rod 202f. When the clamping block moves upward along the bottom end of the through hole 201c, the gap between the two adjacent groups of clamping blocks and the support rod 202f gradually increases until the clamping block moves out of the end of the through hole 201c. At this time, under the elastic force of the support rod 202f, the two adjacent groups of clamping blocks are connected. The gap between them reaches its maximum value, at which time the bottom end of the clamping block contacts the end of the first connecting block 201b, and the connection between the ash hopper 102 and the electrostatic precipitator housing 101 is completed. Next, you can choose whether to weld the ash hopper 102 and the electrostatic precipitator housing 101. If welding is not performed, the connection between the existing electrostatic precipitator and the ash hopper 102 is also completed. Compared with the traditional welding connection method, since the first connecting piece 201 and the electrostatic precipitator housing 101 are integrally formed, and the second connecting piece 202 and the inner wall of the ash hopper 102 are integrally formed, compared with welding, the first connecting piece 201 and the second connecting piece 202 will not produce cracks due to the excessive load of the ash hopper 102. Therefore, at this time, the electrostatic precipitator housing 101 and the ash hopper 102 can be further welded according to the actual usage situation;

[0046] If after the electrostatic precipitator housing 101 and the ash hopper 102 are welded, the weld between the electrostatic precipitator housing 101 and the ash hopper 102 is torn due to excessive tensile force, the first connecting piece 201 and the second connecting piece 202 in the present invention can be connected to each other as a second protection system for the connection between the electrostatic precipitator housing 101 and the ash hopper 102.
