Description

Technical Field

[0001] The utility model relates to an alarm device, in particular to an automatic temperature control alarm system for a cooler in a feed factory. Background Art

[0002] The feed production process involves several key steps: batching, mixing, pelleting, cooling, grading, and packaging. Cooling is a crucial step. Pellets leaving the pellet mill's die should have a maximum temperature of 70°C-100°C and a moisture content of 15%-18%. After cooling, the screened material should be no more than 3°C-5°C above room temperature, and its moisture content should be reduced to 10%-12.5%. This crucial step, accomplished using a cooler, also facilitates feed transportation, storage, and preservation. If the discharge temperature of pellets is too high due to equipment or other issues, this can lead to quality problems such as mold during storage.

[0003] In summary, the utility model designs a feed factory cooler temperature control automatic alarm system. Utility Model Content

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0015] Reference Figure 1-3 This specific embodiment adopts the following technical solution: a feed factory cooler temperature control automatic alarm system, including a temperature sensor BT, a distribution box DB and an alarm HA. The temperature sensor BT is arranged at the discharge port of the cooler 1, and the distribution box DB and the alarm HA are both arranged in the central control room. The distribution box DB is provided with a thermostat SM, a relay KJ, a circuit breaker QF and a control line. The temperature sensor BT is connected to the thermostat SM through a shielded wire, the thermostat SM is connected to the circuit breaker QF, and the alarm HA is connected to the first relay KJ1.

[0016] The live wire L and the neutral wire N in the distribution cabinet are connected to the circuit breaker QF, the live wire L of the circuit breaker QF is connected to the No. 1 terminal of the thermostat SM, the neutral wire N of the circuit breaker QF is connected to the No. 2 terminal of the thermostat SM, the positive pole of the temperature sensor BT is connected to the No. 4 terminal of the thermostat SM, the negative pole of the temperature sensor BT is connected to the No. 3 terminal of the thermostat SM, the No. 7 terminal of the thermostat SM is connected to one end 13 of the coil of the first relay KJ1, and the No. 8 terminal of the thermostat SM is connected to one end 13 of the coil of the second relay KJ2.

[0017] In this specific embodiment, when the equipment starts and operates normally, the thermostat is powered on and starts operating. On the contrary, when the temperature of the pellet feed passing through the temperature sensor BT is higher than the set temperature, the thermostat SM will alarm, the cooler will stop unloading, the alarm will sound, and the control room operator will notify the mechanic to inspect and repair the equipment. After the fault is eliminated, the cooler will operate normally. The alarm working principle is that when the thermostat detects that the discharge temperature is higher than the set temperature, the internal relays SM7 and SM8 of the thermostat SM (both are normally open points, one end of the normally open point is connected to the thermostat terminal 1, both are live wire L) are energized and supply power to one end 13 of the first relay KJ1 coil through the terminal 7. The other end 14 of the first relay KJ1 coil is connected to the neutral wire N. The first relay KJ1 is energized and energized. The normally open contacts 5 and 9 of the first relay KJ1 are connected. Point 5 is connected to the live wire L, and point 9 is connected to the alarm power supply line A1.1. The alarm power supply line A2.1 is connected to the neutral wire N. The alarm BT forms a closed loop and starts working to emit an audible and visual alarm. The internal relay SM8 of the thermostat is energized and supplies power to the coil 13 of the second relay KJ2 through terminal 8. 14 is connected to the neutral line N, and the relay is energized. The 1 and 9 of the relay are a set of normally closed contacts. The contactor KM (KM contactor is the contactor of the original equipment cooler screening motor) is connected to one end of the start control line of the contactor KM, and 9 is connected to the coil 13 of the second relay KJ2. The coil 14 of the second relay KJ2 is connected to the neutral line N. The second relay KJ2 is energized and the normally closed contacts 1 and 9 are disconnected. The contactor KM coil loses power and is disconnected. The cooler screening motor loses power and stops screening. Therefore, when the cooler discharge temperature is higher than the set temperature, an alarm will be issued to stop discharging, which greatly ensures the product quality of the feed and improves the automation of the equipment.

This reduces costs, ensures product quality, and improves the degree of automation of the equipment.
