Description

Technical Field

[0001] The utility model relates to the technical field of tar discharge from an electric tar collector, in particular to a heating discharge device for an electric tar collector. Background Art

[0002] Among the purification systems for pre-baked anode baking, the electric tar collector is a key device, which is mainly used to collect tar in baking flue gas. The device discharges the collected tar from the cone discharge port at the bottom. The lower part of the discharge port cone was originally designed as a square port connected to the lower slag discharge valve, which easily causes tar to accumulate around the inside of the cone, making it impossible to discharge it. During discharge, heating is required to discharge the tar at the bottom smoothly. The device is equipped with a 110KW steam boiler for heating, but the electric steam boiler is prone to scale and frequent failures due to the high hardness of industrial water, resulting in poor heating effect, difficulty in discharging tar at the bottom of the cone, and inconvenient operation. Utility Model Content

[0003] The purpose of the utility model is to provide a heating and discharging device for an electric tar collector, so as to solve the technical problems mentioned in the above background technology.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] The utility model discloses a heating and discharging device for an electric tar precipitator, comprising a slag discharge port, wherein the upper part of the slag discharge port is a square cone-shaped electric field bottom outlet, and the lower part is a cylindrical tar discharge outlet, the lower end of the electric field bottom outlet is connected with the upper end of the tar discharge outlet, a quick-opening valve is arranged at the bottom of the slag discharge port, and a ceramic heating rope is evenly wound on the outer peripheral wall of the slag discharge port.

[0006] Furthermore, the quick-opening valve is provided with a valve handle adapted thereto.

[0007] Furthermore, the ceramic heating rope is specifically configured as a 5.5KW ceramic heating rope.

[0008] Furthermore, a heater hook is fixedly provided on the outer wall of the slag discharge port, and the ceramic heating rope is evenly wound around the outer wall of the slag discharge port through the heater hook.

[0009] Furthermore, the gap between adjacent ceramic heating ropes is 5 cm.

[0010] Compared with the prior art, the beneficial technical effects of the utility model are:

[0011] The utility model sets the slag discharge port of the electric tar collector as a special structure of square and round, which can be suitable for the discharge outlet without power supply, so that the fluid is decomposed into a thin spray form or annular convection to achieve the purpose of impact offset.

[0012] The quick-opening valve with full-body opening is used to quickly control the dynamic material flow. The operation is simple, and the flow control or cut-off can be achieved quickly by manually controlling the valve handle.

[0013] The slag discharge port is heated by a ceramic heating rope, which has high high temperature resistance, can work stably for a long time in a high temperature environment, and has fast heating and cooling speeds and low energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] like Figure 1 As shown, a heating discharge device for an electric tar collector includes a slag discharge port 1, the upper part of the slag discharge port 1 is a square cone-shaped electric field bottom outlet 1-1, and the lower part is a cylindrical tar discharge port 1-2, the lower end of the electric field bottom outlet 1-1 is connected to the upper end of the tar discharge port 1-2, and the two are fixedly connected by welding. The above-mentioned slag discharge port design with a square structure can be applied to a discharge outlet without power supply, so that the fluid is decomposed into a thin spray form or annular convection to achieve the purpose of impact offset.

[0018] A quick-opening valve 2 is installed at the bottom of the slag discharge port, and a valve handle 3 adapted thereto is installed on the quick-opening valve 2. The valve handle 3 is easy for the staff to manually operate, so that the quick-opening valve can be opened or closed quickly, and the dynamic material flow can be quickly controlled. The operation is simple, and manual control can achieve rapid flow control or cut-off.

[0019] A ceramic heating rope 4 is evenly wound on the outer wall of the slag discharge port 1. In this embodiment, the ceramic heating rope 4 is specifically a 5.5KW ceramic heating rope. A heater hook 5 is fixedly arranged on the outer wall of the slag discharge port 1. The ceramic heating rope 4 is evenly wound on the outer wall of the slag discharge port 1 through the heater hook 5. In this embodiment, the gap between adjacent ceramic heating ropes is 5 cm.

[0020] When the utility model is in operation, before preparing to discharge tar, the ceramic heating rope is first energized for 30 minutes. When the tar is softened to the discharge standard, the valve handle is directly operated to open the quick opening at the bottom of the cone, so that the tar can be discharged smoothly. After use, the quick opening valve can be quickly closed and the ceramic heating power supply can be turned off.
