Description

Technical Field

[0001] The utility model relates to a secondary feeding detection device for a dust collector, belonging to the technical field of dust feeding in electrolytic aluminum dust removal. Background Technique

[0002] The secondary feeding of the electrolytic aluminum dust collector refers to the process that after the dust collector runs for a period of time with the first feeding during the electrolytic aluminum production process, due to various reasons (such as raw material consumption, decline in dust removal effect, etc.), it is necessary to carry out the operation of feeding again.

[0003] In the process of implementing the technical solution of the present application, the inventor found that there are at least the following technical problems in the prior art:

[0004] Aiming at the position of the secondary feeding of the dust collector inside the inlet flue of the dust collector box body, because the secondary feeding hole is small, and at the same time, it is necessary to suck out the smoke and dust formed during the feeding process from the secondary feeding hole, so as to ensure the production environment inside the production workshop. Due to the small hole, it is easy to cause blockage. After blockage, manual dredging is required. Since there are many secondary feeding holes in the workshop, frequent dredging is required. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a secondary feeding detection device for a dust collector, which uses the internal temperature rise to obtain the blockage data of the secondary feeding hole, so as to carry out fixed-point cleaning.

[0006] The secondary feeding detection device for a dust collector described in the utility model includes a dust collector. There is a feeding chamber inside the dust collector. One side of the feeding chamber is connected with a negative pressure smoke exhaust duct. The lower end of the feeding chamber is connected with a feeding pipeline. The feeding pipeline is connected with a production chamber. A bracket is installed on the outer side wall of the feeding chamber. An air compressor is installed on the bracket. One end of the feeding chamber is connected with the air compressor through an air inlet pipe. A temperature detection mechanism extending into the feeding chamber is installed on the inner wall of the feeding chamber.

[0007] Further, the bracket includes a triangular bracket. A support plate is installed on the triangular bracket. The air compressor is fixedly installed on the support plate.

[0008] Further, the temperature detection mechanism is a temperature sensor, and the inspection head of the temperature sensor extends into the feeding chamber.

[0009] Further, an electromagnetic valve is also provided on the air inlet pipe. A branch air pipe is installed on the air inlet pipe between the electromagnetic valve and the air compressor. The branch air pipe is connected with other feeding chambers. Electromagnetic valves are respectively provided on the air inlet pipes of other feeding chambers. Corresponding temperature detection mechanisms are provided inside other feeding chambers.

[0010] Further, an electrical control cabinet is arranged on one side of the air compressor on the bracket.

[0011] Furthermore, the electrical control cabinet is arranged close to the feeding chamber.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] By arranging a temperature detection mechanism inside the feeding chamber, the present utility model can detect the temperature change inside the feeding chamber in real time, so as to judge whether the secondary feeding hole is blocked. When the secondary feeding hole is blocked, the temperature inside the feeding chamber will rise, and the temperature detection mechanism can timely capture this change and send an alarm signal through the control system to remind the staff to clean and dredge.

[0014] By arranging an air compressor to blow air into the feeding chamber, the air pressure inside the feeding chamber is increased to blow down the blocked material, and then dust removal treatment is carried out. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Embodiment 1

[0022] As Figures 1 to 4 shown, the secondary feeding detection device of the dust collector of the present utility model includes a dust collector 2. A feeding chamber is arranged inside the dust collector 2. One side of the feeding chamber is connected with a negative pressure smoke exhaust duct 1. The lower end of the feeding chamber is connected with a feeding pipe 5. The feeding pipe 5 is connected with a production chamber 6. A bracket 8 is installed on the outer side wall of the feeding chamber. An air compressor 4 is installed on the bracket 8. One end of the feeding chamber is connected with the air compressor 4 through an air inlet pipe. A temperature detection mechanism 3 extending into the inside of the feeding chamber is installed on the inner wall of the feeding chamber.

[0023] The bracket 8 includes a triangular bracket 82. A support plate 81 is installed on the triangular bracket 82. The air compressor 4 is fixedly installed on the support plate 81.

[0024] The temperature detection mechanism 3 is a temperature sensor, and the inspection head of the temperature sensor extends into the feeding cavity.

[0025] An electromagnetic valve 42 is also provided on the air inlet pipe. A manifold 41 is installed on the air inlet pipe between the electromagnetic valve 42 and the air compressor 4. The manifold 41 is connected to other feeding cavities. Electromagnetic valves 42 are respectively provided on the air inlet pipes of other feeding cavities, and corresponding temperature detection mechanisms 3 are provided in other feeding cavities.

[0026] An electrical control cabinet 7 is arranged on one side of the air compressor 4 on the bracket 8.

[0027] The electrical control cabinet 7 is arranged close to the feeding cavity.

[0028] The design of the bracket and the electrical control cabinet makes the whole device have a compact structure and a reasonable layout, which is convenient for installation and maintenance. The arrangement of the electrical control cabinet close to the feeding cavity is beneficial to reducing the wire length, lowering the energy consumption, and at the same time facilitating the staff to monitor and operate.

[0029] Working process or working principle:

[0030] By setting a temperature detection mechanism inside the feeding cavity, the temperature change inside the feeding cavity can be detected in real time, so as to judge whether the secondary feeding hole is blocked. When the secondary feeding hole is blocked, the temperature inside the feeding cavity will rise. The temperature detection mechanism can promptly capture this change and send an alarm signal through the control system to remind the staff to clean and dredge.

[0031] In the present utility model, the description of the directions and relative position relationships of the structures, such as the descriptions of front, back, left, right, up, and down, does not constitute a limitation to the present utility model, but is only for the convenience of description.
