Description

Technical Field

[0001] This utility model relates to the technical field of aluminum granule production equipment, specifically to a bag filter pressure balance tank for aluminum granule production. Background Technology

[0002] Aluminum granules are generally made from aluminum ingots through processes such as wire drawing, cutting, and grinding. During the production of aluminum granules, a bag filter is required for dust removal. During the dust removal process, a pressure balancing tank is usually used to balance the pulse air pressure inside the filter bag to ensure production stability.

[0003] For example, CN 202438467 U discloses an aluminum powder grading production line, which includes a feeding device connected in sequence, at least two classifiers connected in series, a cyclone collector, a bag filter, and an induced draft fan. Each of the two classifiers is equipped with a secondary air intake device. A pressure balance tank is connected downstream of the induced draft fan, and the pressure balance tank is equipped with a nitrogen replenishment port. The pressure balance tank is connected to the secondary air intake device of each classifier. However, in northern regions, especially the three northeastern provinces, winter temperatures are extremely low. Without insulation, the pressure balance tank is likely to freeze inside. This freezing can easily cause the pressure regulation function inside the tank to fail, thus affecting the normal operation of the entire aluminum powder or aluminum granule production system. Utility Model Content

[0004] The purpose of this invention is to provide a bag filter pressure balance tank for aluminum granule production that has a reasonable structure and reliable operation, solving the problem of ice formation inside the tank at extremely low temperatures, ensuring the pressure regulation function, and thus guaranteeing the normal operation of the aluminum granule production system.

[0005] The technical solution of this utility model is:

[0006] A pressure balancing tank for baghouse dust collection in aluminum granule production includes a pressure balancing tank body. The key technical features are: two heating components, upper and lower, are spaced apart on the outer peripheral wall of the pressure balancing tank body. Each heating component includes two symmetrically arranged arc-shaped hollow clamps, bolt pairs connecting the opposite ends of the two arc-shaped hollow clamps, multiple heating rods spaced apart along the upper surface of the arc-shaped hollow clamps, a pad layer disposed on the inner arc surface of the arc-shaped hollow clamps, and a heat storage medium located within the arc-shaped hollow clamps. The heating rods are longitudinally inserted into the arc-shaped hollow clamps from their upper surface. A temperature sensor is installed on the outlet pipe of the pressure balancing tank body. A make-up air pipe is provided on the top side of the pressure balancing tank body. The outer end of the make-up air pipe is connected to the outlet of a dryer, and the inlet of the dryer is connected to a nitrogen supply pipe.

[0007] The aforementioned bag filter pressure balance tank for aluminum granule production has an annular heat-conducting coating on the outer peripheral wall of the tank body, corresponding to the arc-shaped hollow clamp.

[0008] The aforementioned bag filter pressure balance tank for aluminum granule production has a fixed frame at the bottom of the tank body. The arc-shaped hollow clamp of the heating component located below is supported on the upper surface of the fixed frame, and multiple retractable support columns are provided between the arc-shaped hollow clamps of the two heating components.

[0009] The aforementioned bag filter pressure balance tank for aluminum granule production comprises a retractable support column consisting of a sleeve with two threaded sections of opposite rotation, a forward-rotating stud and a reverse-rotating stud connected to both ends of the sleeve, and a supporting frustum at the outer ends of the forward-rotating stud and the reverse-rotating stud, respectively.

[0010] The aforementioned bag filter pressure balance tank for aluminum granule production includes a dryer comprising an outer shell, multiple lower baffles spaced apart along the bottom surface of the outer shell, and multiple upper baffles spaced apart along the top surface of the outer shell. The upper and lower baffles are arranged alternately and form a serpentine gas channel within the outer shell. The inlet of the serpentine gas channel is connected to a nitrogen supply pipeline, and the outlet of the serpentine gas channel is connected to a make-up gas pipeline. A drain pipe is provided on the bottom surface of the inlet of the serpentine gas channel, and a drain valve is provided at the lower end of the drain pipe. A liquid passage hole is provided at the lower end of the lower baffles.

[0011] The aforementioned bag filter pressure balance tank for aluminum granule production has an upper baffle and a lower baffle, both of which are activated carbon baffles.

[0012] The beneficial effects of this utility model are:

[0013] 1. On the one hand, the temperature of the pressure balance tank body is regulated by the heating component to solve the problem of ice formation inside the tank when the temperature is extremely low, thereby ensuring the pressure regulation function of the pressure balance tank and ensuring the normal operation of the aluminum granule production system.

[0014] 2. It can modify the original pressure balance tank body. First, apply an annular heat-conducting coating to the position where the heating component is pre-installed. Then, clamp two arc-shaped hollow clamps on the outside of the annular heat-conducting coating. Then, according to the feedback signal of the temperature sensor, activate the corresponding number of heating rods to quickly heat and conduct heat, so as to ensure the internal temperature of the pressure balance tank body, avoid freezing, and make it flexible and convenient to use.

[0015] 3. Use a dryer to dry the introduced gas to avoid high moisture content. Attached Figure Description
