The working process is as follows:
the raw material sand is conveyed by the belt conveyor 1 and then falls onto the vibrating screen 22 of the screening mechanism 2. Due to the inclined arrangement of the vibrating screen 22, under the action of the vibrating motor 21, the sand starts to slide downwards on the mesh surface of the vibrating screen 22, and during the sliding process, the sand meeting the production requirements enters the receiving hopper 23 through the mesh surface and further enters the outer sleeve 35 through the feeding hole 36 in the heating mechanism 3 for heating. The large-particle-size stones which fail to pass through the net surface slide down along the net surface and finally fall into the sand box 24, so that the stones cannot enter the machine to cause damage to equipment.
Two ends of the spiral belt 35 in the heating mechanism 3 are connected with steam interfaces, and when sand meeting production requirements enters the heating mechanism 3, high-temperature steam is introduced into the spiral belt 35 from the steam inlet 310 to transfer heat to the spiral belt 35. The spiral belt 35 is rotated by the rotating motor 31, and heat generated by the high-temperature steam is transferred to the sand through contact between the wall surface and the sand during stirring. The spiral belt 35 heats the sand while stirring the sand, so that the sand is heated more uniformly and continuously, and finally the high-temperature steam is changed into low-temperature gas to be discharged from the steam outlet 38. A temperature sensor is provided near the discharge port 39 to form negative feedback with the rotary motor 31, and the rotation speed of the rotary motor 31 can be adjusted according to the temperature. If the temperature of the sand is below the desired temperature range, the temperature sensor will send a signal to the rotary motor 31 to reduce the speed of the rotary motor 31, allowing the sand to remain in the outer sleeve 34 for a longer period of time, allowing the helical belt 35 to contact the sand for a longer period of time, and allowing the sand to be heated more, thereby increasing the temperature of the sand. Otherwise, the temperature sensor sends a signal to the rotating motor 31 to increase the rotation speed to ensure that the temperature of the sand is within a proper range.
The spiral belt 35 is provided with a hollow channel inside, and the connection with the steam inlet 310 is provided with an air hole, so that steam can enter the spiral belt 35. The contact position of the annular shell and the end part of the spiral belt 35 is provided with a self-lubricating bearing 312 and a seal 313, so that when the spiral belt 35 rotates to heat sand, steam can smoothly enter the spiral belt 35, and the steam is kept from leaking.
The sand, while heated, is conveyed with agitation to the discharge port 39 and falls into a hopper 44 in the conveyor mechanism 4. Hopper 44 is the slope and arranges, has hopper support 43 to support down, and accessible steering motor 41 drives gear 45 and rotates, and then drives whole hopper 44 and hopper support 43 and rotate in bearing III 42 to send grit to suitable position and carry out next process or production activity.
This device can use alone and heat as solitary equipment, also can install in storage factory building or high feed bin upper portion suitable position, uses as one of them functional unit, as the heat treatment before putting into storage and keeping warm.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
