Description
Technical field
The utility model relates to means for correcting, specifically a kind of bulking machine discharging density automatic control device.
Background technique
In feed production technology, bulking machine discharging density is one of most important process of feed processing, close by controlling
The pressure of degree control room can adjust the puffed degree of product, when the hot material by mediating is extruded into from bulking machine discharging machine boring
When atmospheric pressure, the moisture in hot material can acutely boil immediately.
When hot material since heat and the effect mediated simultaneously is adequately gelatinized, countless steam will be generated in material
Bubble thus causes the reduction of expansion chamber's material density.When the boiling point of moisture in the pressure increase of density domination room, particle also can
It improves, the result of this effect, which may make in material, only has smaller part of moisture to evaporate, and the expansion of such particle will
It reduces, therefore can reach higher density.Existing bulking machine discharging density is by pressure gauge mostly in density domination room
Pressure be monitored, then by manually being controlled, control difficulty is larger.
Summary of the invention
The utility model is insufficient according to prior art, provides a kind of bulking machine discharging density automatic control device, this is close
Degree control device may be implemented to automatically control the pressure value of density domination room, to automatically control discharging density.
Technical solution provided by the utility model: a kind of bulking machine discharging density automatic control device, including extruding
The boring of machine discharging machine and the density domination room closely coupled with it, the airlock that the discharge port in density domination room is tightly connected,

It sets and density domination room is led to by admission line and tee tube with electronic air intake valve, the electronic air intake valve, it is described automatic
The third interface of tee tube is arranged in pressure releasing device, and is connected to by tee tube with density domination room, the pressure control device packet
Include pressure sensor and PLC controller, pressure sensor is arranged on admission line, the signal output end of pressure sensor with
The signal input part of PLC controller connects, the signal output end of PLC controller respectively with electronic relief valve and electronic air intake valve
Control terminal connection.
The utility model preferably technical solution: density domination room rear end is connected with frequency conversion blank motor.
The inlet and outlet of density domination room described in the utility model and the boring of bulking machine discharging machine and airlock are closely coupled, protect
A sealed environment is demonstrate,proved, density domination room top is equipped with automatic leakage depressor and pressure control device, and pressure control device connects

The leakproofness of control room discharging, pressure control device adjust the opening degree of electronic pressure releasing device and electronic air intake valve by PLC,
Control enters the air capacity of pressure controller to obtain correct setup pressure value.
The pressure controller of the utility model can automatically record the pressure value of density domination room, adjust automatic leakage by PLC
The controllable air capacity into pressure controller of the opening degree of depressor and electronic air intake valve is to obtain correctly setting pressure
Value is realized and automatically controls discharging density, effectively reduces the difficulty and workload of traditional artificial control, improve the operation of bulking machine
Property, and structure is simple and convenient to operate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the pneumatic diagram of the utility model.
In figure: 1-bulking machine discharging machine boring, 2-density domination rooms, 3-electronic relief valves, 4-pressure control devices,
5-electronic air intake valves, 6-frequency conversion blank motors, 7-airlocks, 8-admission lines, 9-tee tubes.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
A kind of bulking machine discharging density automatic control device as depicted in figs. 1 and 2, including 1 He of bulking machine discharging machine boring
The density domination room 2 closely coupled with it, 2 rear end of density domination room are connected with frequency conversion blank motor 6, density domination room 2
Import and bulking machine discharging machine boring 1 sealing dock, in the airlock 7 of the discharge port sealed connection of density domination room 2, pass through pass
Wind device 7 and its 2 surrounding of density domination room are in sealing state, it is characterised in that: electronic relief valve is equipped on density domination room 2
3, pressure control device 4 and electronic air intake valve 5, the electronic air intake valve 5 are led to close by admission line 8 and tee tube 9
Spend control room 2.
As shown in Fig. 2, the first interface of the tee tube 9 is connected to admission line 8, the pressure control device 4 includes
Pressure sensor and PLC controller, pressure control device 4 are arranged in admission line 8 and threeway connecting portion, pressure sensor
It is placed in admission line 8, the second interface of tee tube 9 is connected to the sealing of density domination room 2, and automatic leakage depressor 3 is arranged in threeway
Electronic air intake valve 5, electronic relief valve 3 are connected to density domination room 2 by tee tube 9, pass through pressure by the third interface of pipe 9
Force control device 4 monitors the pressure in density domination room 2.
The signal output end of 4 pressure sensor of pressure control device and the signal input part of PLC controller connect,
