Abstract

The utility model discloses a control cabinet for a ceramic roll track kiln furnace, which relates to improvement of lines. Through intermediate relays, normally open contacts J< 3 >, J< 4 >, J< 5 >, J< 6 >, J< 7 >, and J< 8 > are respectively connected to manual buttons SB< 11 >, SB< 31 >, SB< 51 >, SB< 61 >, SB< 81 >, and SB< 91 > in parallel; the normally closed contacts of the intermediate relays KM< 11 >, KM< 21 >, KM< 31 >, KM< 41 >, KM< 61 >, and KM< 71 > are respectively connected to stop buttons SB< 22 >, SB< 12 >, SB< 42 >, SB< 32 >, SB< 72 >, and SB< 61 > in series; manual and automatic arbitrary conversion can be obtained, and regular production can not be affected. The control cabinet for a ceramic roll track kiln furnace makes a general motor and a spare motor mutually locked, and because of false operation, the production of the control cabinet for a ceramic roll track kiln furnace can not be affected.

Description

A kind of ceramic roller kiln switch board

The utility model relates to ceramic roller kiln control circuit.

At present, domestic ceramic roller Kiln Control System has two major types, first is made of A.C. contactor, the time relay, button and change-over switch etc., this system does not have automation control, started by control manually fully, commonly used and standby motor is finished by change-over switch, causes fault to disperse like this, when workman's misoperation, go out production accident easily and influence product quality or burn out frequency converter or circuit because of electric current is excessive.Second type is the control system that has control able to programme, manually with is automatically changed by change-over switch, and this type be able to programme being out of order in a single day, and the whole piece kiln is out of control, and the maintenance that must stop production.

The utility model purpose is the shortcoming according to above two type control systems, and a kind of reliable roller way kiln control system that has is provided.

For achieving the above object, the utility model solution is auxiliary reclay J ₃, J ₄, J ₅, J ₆, J ₇, J ₈Normally open contact be parallel to hand push button SB respectively ₁₁, SB ₃₁, SB ₅₁, SB ₆₁, SB ₈₁, SB ₉₁Auxiliary reclay KM ₁₁, KM ₂₁, KM ₃₁, KM ₄₁, KM ₆₁, KM ₇₁Normally closed interlock be series at SB respectively ₂₂, SB ₁₂, SB ₄₂, SB ₃₂, SB ₇₂, SB ₆₁

Owing to adopt such scheme can make manually and conversion and do not influence production arbitrarily automatically, is automatic switching manually with conversion automatically, motor commonly used is with standby motor interlocking and because of maloperation influence production.

Fig. 1 is a control circuit able to programme of the present utility model;

Fig. 2 is an Electric Machine Control circuit of the present utility model;

Fig. 3 is a motor of the present utility model supply line.

As Fig. 1, Fig. 2, shown in Figure 3, when Programmable Logic Controller 1 is received K ₁Automatically activated signal the time, make auxiliary reclay J respectively by certain time interval ₃, J ₄, J ₅, J ₆, J ₇, J ₈Coil electricity, its normally open contact are closed respectively, by logical auxiliary reclay KM ₁₁, KM ₃₁, KM ₅₁, KM ₆₁, KM ₈₁, KM ₉₁Coil, its normally open contact closure, normally closed interlock is opened, dehumidifier trigger circuit 2, atomizing trigger circuit 4, take out hot exposure circuit 8, combustion-supporting trigger circuit 6, cooling trigger circuit 10, chilling trigger circuit 9 is switched in succession and start each motor and run well.When Programmable Logic Controller 1 breaks down, auxiliary reclay KM ₁₁, KM ₃₁, KM ₅₁, KM ₆₁, KM ₈₁, KM ₉₁Still closure and motor operate as normal.When need were manual, SB touched the button ₁₁, SB ₃₁, SB ₅₁, SB ₆₁, SB ₇₁, SB ₈₁Make auxiliary reclay KM ₁₁, KM ₅₁, KM ₆₁, KM ₇₁, KM ₈₁Coil electricity and after its normally open contact closure, each electric motor starting circuit is connected.When in operate as normal, by last standby electric motor starting line button SB ₂₁, SB ₄₁, SB ₇₁, because of auxiliary reclay normally closed interlock KM ₁₁, KM ₃₁, KM ₆₁Still open and can not connect standby electric motor starting circuit.
