Abstract
The utility model relates to a tectorial membrane sand production line, including sieving mechanism and cooling elevator, cooling elevator includes hoisting device and cooling device, hoisting device including be used for with the hoisting device feed inlet of the discharge gate intercommunication of sieving mechanism with be used for carrying tectorial membrane sand to cooling device's hoisting device discharge gate, cooling device include with the slide that is used for downwash tectorial membrane sand of hoisting device discharge gate intercommunication, be provided with the cooling water course that is used for carrying on the heat exchange with the slide on the diapire of slide. Realized cooling down the higher tectorial membrane sand of temperature after the sieving mechanism screening through this cooling elevator, shortened the bagging -off warehouse entry time of the higher tectorial membrane sand of the temperature after the screening, reduced workman's intensity of labour, improved production efficiency.
Description
Technical field
The utility model relates to a kind of precoated sand production line.
Background technology
Precoated sand refers to before moulding, be covered with one deck hard resin at sand grain surface molding sand or core sand.There are cold process and Re Fa two kinds of coating techniques, hot method coating technique is that the sand grains of roughing sand is preheating to uniform temperature, add resin and make its melting, then stirring makes resin-coating at sand grain surface, adding the curing agent methenamine aqueous solution and the lubricant preventing sand grains from luming and the additive for improving precoated sand performance, obtaining precoated sand through broken, cooling, screening.Current most enterprises is when producing precoated sand, after the precoated sand system of mixing completes, also need through broken scalping, cooling and dusting cover, but the precoated sand temperature after dusting cover is still general higher, at about 80 DEG C, directly can not pack warehouse-in, need manually to spread out to ground or after naturally cooling to uniform temperature and just can carry out pack warehouse-in, cause the labour intensity adding workman, reduce production efficiency.
Utility model content
For solving problems of the prior art, the purpose of this utility model is to provide a kind of precoated sand temperature higher with temperature after making crushing and screening with coolelevator to reduce the precoated sand production line that directly can pack warehouse-in.
The utility model adopts following technical scheme: a kind of precoated sand production line, comprise screening plant and coolelevator, coolelevator comprises lifting device and is arranged at the cooling device on the right side of lifting device, lifting device comprises the lifting device charging aperture for being communicated with the discharging opening of screening plant and the lifting device discharging opening for precoated sand being delivered to cooling device, cooling device comprises the slideway for carrying precoated sand be downwards communicated with lifting device discharging opening, the diapire of slideway is provided with for carrying out the cooling water channel of heat exchange with slideway.
Described slideway comprises at least two supply units arranged up and down, and each supply unit includes carrier pipe and lower carrier pipe, and upper and lower carrier pipe forms the v-shaped structure of recess towards the right side.
Described cooling water channel comprises the upper cooling water channel be arranged on carrier pipe and the lower cooling water channel be arranged on lower carrier pipe, and upper and lower cooling water channel was connected by communicating pipe.
The bottom of the v-shaped structure of the supply unit of described slideway is fixed on the sidewall of lifting device.
Described cooling device also comprises the water inlet pipe of input cold water and exports the outlet pipe of hot water, and described water inlet pipe is connected with the upper cooling water channel of supply unit topmost, and described outlet pipe is connected with the lower cooling water channel of supply unit bottom.
Described lifting device is provided with the ladder climbed up and down for maintenance or maintainer.
The beneficial effects of the utility model are: increase coolelevator at screening plant subsequent process, coolelevator comprises lifting device and cooling device, lifting device comprises lifting device charging aperture and lifting device discharging opening, and cooling device comprises slideway and is arranged at slideway and carries out the water channel of heat exchange with slideway.The precoated sand achieving the temperature after being sieved by screening plant higher is lowered the temperature by this coolelevator, shortens the pack entry time of the higher precoated sand of the temperature after screening, reduces the labour intensity of workman, improve production efficiency.

Fig. 1 is the structural representation of an embodiment of a kind of precoated sand production line of the present utility model;
Fig. 2 is the rearview of Fig. 1;
Fig. 3 is the structural representation of cooling device.
Detailed description of the invention
A kind of precoated sand production line, as shown in Figure 1, comprise screening plant 6 and coolelevator, coolelevator comprise the lifting device 1 for precoated sand being risen to certain altitude and be arranged at lifting device right side be used for the cooling device 2 that the precoated sand higher to temperature after screening lower the temperature, lifting device 1 comprises the lifting device charging aperture 7 for being communicated with the discharging opening of screening plant 6 and the lifting device discharging opening 8 for precoated sand being delivered to cooling device 2, cooling device 2 comprise be connected with lifting device discharging opening 8 and slideway 10 for circulating from top to bottom for precoated sand, be arranged on slideway 10 diapire for carrying out the cooling water channel of heat exchange with slideway 10, to the water inlet pipe 4 of cooling device input cold water and the outlet pipe 5 of discharge hot water, slideway 10 comprises 4 supply units 15, each supply unit 15 includes the upper carrier pipe 11 and lower carrier pipe 12 arranged up and down, on, lower carrier pipe forms the v-shaped structure of recess towards the right side, cooling water channel comprises the upper cooling water channel 13 be arranged on carrier pipe 11 and the lower cooling water channel 14 be arranged on lower carrier pipe 12, on, lower cooling water channel was connected by communicating pipe 3, to ensure that cooling water slowly circulates, take away more heat water-saving simultaneously.Water inlet pipe 4 is connected with the upper cooling water channel of supply unit topmost, and outlet pipe 5 is connected with the lower cooling water channel of supply unit bottom.Lifting device 1 comprises lifting device body and is arranged at the lifting subassembly of lifting device inside, the bottom of the v-shaped structure of each supply unit of slideway 10 is fixed on the sidewall of lifting device body, ensure that cooling device has enough intensity, lifting device body is provided with the ladder 9 climbed up and down for maintenance or maintainer.
In other embodiments of the present utility model, water inlet pipe also can be connected with the lower cooling water channel of supply unit bottom, and outlet pipe also can be connected with the upper cooling water channel of supply unit topmost; Lifting device also can not arrange ladder; Cooling device also can not be connected with lifting device body when having enough intensity in the guarantee course of work; Slideway also can make spiral ramp, bottom spiral ramp, arrange water channel.
