Machine cavity cooling device for purified cotton grinder
The utility model relates to a kind of machine cavity cooling devices for purified cotton grinder, belong to chemical production equipment technology
The raw material refining cotton of cellulose ether production, adds reaction kettle after need to being ground into cotton powder.And purified cotton crushes
During crushing purified cotton, crushing machine cutting tool runs at high speed machine, constantly cut, powder cotton knife temperature increase, machine cavity temperature with
The extension of pulverizer working time, machine cavity temperature gradually rise.Machine cavity temperature, which increases, to be easy, and is easy to appear overtemperature and is caused fire
The security risks such as calamity, explosion.Purified cotton grinder when the temperature is excessively high, need to suspend use, reduce its temperature naturally, also affect
Utility model content
The purpose of the utility model is to overcome the drawbacks described above of existing geothermal well well head backflow device, propose a kind of use
In the machine cavity cooling device of purified cotton grinder, simple structure and reasonable design.
The utility model, which is that the following technical solution is employed, to be realized:
A kind of machine cavity cooling device for purified cotton grinder, including pulverizing device frame, the side of pulverizing device frame are set
It is equipped with motor, motor output end connects shaft by belt, and shaft is deep into pulverizing device frame to be connected with cutter, outside cutter
Side is provided with sieve, and it further includes water tank that pulverizing device frame bottom, which is provided with discharge port, and water tank is connected with cold water pipes, and water tank connects
Feed channel is tapped into, admission line is connected after passing through water tank with air outlet, and the top of pulverizing device frame, pulverizer is arranged in air outlet
The bottom of rack is additionally provided with discharge pipe, and the position that discharge pipe is connected with pulverizing device frame is additionally provided with filter screen.
7 DEG C of circulating chilled water enters water tank in cold water pipes, and admission line cools down across water tank, by air outlet by cold wind
It is blown into pulverizer, reduces the temperature of pulverizer, bottom has been provided with discharge pipe, is being crushed cold wind introducing by discharge pipe
Motor spindle, make cold wind pass through pulverizer, while the filter screen of the discharge pipe position of pulverizing device frame bottom can prevent product into
Enter into discharge pipe, influences discharge pipe.
Further preferred, the admission line ring-wound keeps admission line abundant with water tank in the outside of water tank
It is further that preferably the air outlet is up-narrow and down-wide open shape, air outlet be arranged in cutter just on
Side is conducive to outlet air, while being more conducive to reduce tool temperature.
The beneficial effects of the utility model are:
(1) the machine cavity cooling device described in the utility model for purified cotton grinder is admission line by water tank
Interior air cooling-down prevents purified cotton grinder from shutting down because temperature is excessively high to cool down for pulverizer；
(2) the machine cavity cooling device described in the utility model for purified cotton grinder, the discharge pipe of bottom setting, matches
The air outlet of the setting for the side of closing, forms convection current in pulverizer, so that pulverizer cooling effect is more preferable.
Detailed description of the invention
Fig. 1 is the design drawing of the utility model embodiment；
In figure: 1, cold water pipes；2, water tank；3, admission line；4, air outlet；5, pulverizing device frame；6, sieve；7, knife
Tool；8, shaft；9, motor；10, belt；11, discharge port；12, filter screen；13, discharge pipe.
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of machine cavity cooling device for purified cotton grinder described in the utility model, including crush
Machine rack 5, the side of pulverizing device frame 5 are provided with motor 9, and 9 output end of motor connects shaft 8 by belt 10, and shaft 8 is goed deep into
It is connected in pulverizing device frame 5 with cutter 7, the outside of cutter 7 is provided with sieve 6, and 5 bottom of pulverizing device frame is provided with discharge port
11, it further include water tank 2, water tank 2 is connected with cold water pipes 1, and water tank 2 connects admission line 3, after admission line 3 passes through water tank 2
It is connected with air outlet 4, the top of pulverizing device frame 5 is arranged in air outlet 4, and the bottom of pulverizing device frame 5 is additionally provided with discharge pipe
13, the position that discharge pipe 13 is connected with pulverizing device frame 5 is additionally provided with filter screen 12.3 ring-wound of admission line
In the outside of water tank 2.The air outlet 4 is up-narrow and down-wide open shape, and the surface of cutter 7 is arranged in air outlet 4.
The course of work of the utility model is as described below: after purified cotton grinder booting, 7 DEG C are passed through in cold water pipes 1
Cold water enters in water tank 2, and circulation outflow always.Admission line 3 passes through air outlet 4 to purified cotton powder after being wrapped in water tank 2
Broken machine blows out cool breeze, especially cools down to cutter 7, while the discharge pipe 13 of bottom can continue exhausting, outlet air under the drive of blower
The filter screen 12 of 13 top of pipe can prevent cotton powder from entering in discharge pipe 13, while discharge pipe 13 and the formation of top outlet inlet 4
Convection current, cooling effect are more preferable.
The utility model mainly applies to the place of the machine cavity cooling of purified cotton grinder.
Certainly, above content is only the preferred embodiment of the utility model, be should not be construed as limiting practical new to this
The scope of embodiments of type.The utility model is also not limited to the example above, and those skilled in the art are in this reality
With all the changes and improvements etc. made in novel essential scope, the patent covering scope of the utility model should all be belonged to
