Description

Technical Field

[0001] The utility model relates to the technical field of temperature controllers, and particularly relates to a temperature control meter for fertilizer production. Background Art

[0002] In the process of fertilizer production, since a reactor is needed to react some production raw materials, a temperature control meter is required to monitor and adjust the temperature of the reactor, the temperature of the heating system, etc., to ensure that the chemical reaction of the fertilizer raw materials occurs under suitable temperature conditions, so as to produce high-quality fertilizer products.

[0003] When the existing temperature control meter is installed on the control panel or instrument panel, the temperature control meter may need to be installed in an embedded manner. This method requires corresponding installation holes or slots to be reserved and the temperature control meter to be embedded therein to make its appearance neat and not affect the layout of other devices. However, when installing through this installation method, screw fixing parts also need to be installed outside the temperature control meter to fix the temperature control meter from inside the control panel or instrument panel, so as to realize the installation of the temperature control meter. However, the internal screw installation points of different control panels or instrument panels are different, so it is easy to occur that the screws for installing the temperature control meter cannot be aligned with the screw grooves in the control box, resulting in the situation that the temperature control meter cannot be installed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a temperature control meter for fertilizer production, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A temperature control meter for fertilizer production includes a main control box. A plurality of connection terminals are fixedly installed at the rear end of the main control box. A plurality of heat dissipation channels are opened at the top and bottom of the main control box. An operation panel is fixedly installed at the front end of the main control box, and the operation panel is electrically connected to the main control board in the main control box through a connecting wire. An installer is arranged outside the main control box. The installer includes a collar. Pressure blocks are respectively movably installed at the circumferential corner positions of the collar. Operating rods are movably installed in the pressure blocks. Two side plates are fixedly installed on the outer side of the collar.

[0007] Preferably, a plurality of card slots are opened at the outer corner positions of the main control box.

[0008] Preferably, a rubber ring is fixedly installed at the front end of the side plate. With the arrangement of the rubber ring, the front side of the collar can contact the fixed object through the rubber ring, so as to ensure that the main control box can be fixedly installed in the installation slot of the installation device by means of a plurality of pressure blocks and the operation panel.

[0009] Preferably, a plurality of installation through grooves are formed in the side plate. Forming a plurality of installation through grooves in the side plate enables the installer to also cooperate with screws to install the main control box in the installation device.

Detailed implementation mode

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0021] As Figures 1 - 5 shown, a temperature control meter for fertilizer production provided by the present utility model includes a main control box 1. A plurality of connection terminals 2 are fixedly installed at the rear end of the main control box 1. A plurality of heat dissipation channels 3 are opened at both the top and bottom of the main control box 1. An operation panel 4 is fixedly installed at the front end of the main control box 1, and the operation panel 4 is electrically connected to the main control board in the main control box 1 through a connecting wire. An installer 5 is arranged outside the main control box 1. The installer 5 includes a collar 6. Pressing blocks 7 are respectively movably installed at the circumferential corner positions of the collar 6. An operating rod 8 is movably installed in the pressing block 7. Two side plates 9 are fixedly installed on the outer side of the collar 6.

[0022] A plurality of card slots 10 are provided at the outer corner positions of the main control box 1. A rubber ring 11 is fixedly installed at the front end of the side plate 9. With the arrangement of the rubber ring 11, the front side of the collar 6 can contact a fixed object through the rubber ring 11, so as to ensure that the main control box 1 can be fixedly installed in the installation slot of the installation device by means of a plurality of pressing blocks 7 and the operation panel 4. A plurality of installation through slots 12 are provided in the side plate 9. By providing a plurality of installation through slots 12 in the side plate 9, it can be realized that the installer 5 can also cooperate with screws to install the main control box 1 in the installation device. A telescopic slot 13 is provided at each of the four corner positions inside the collar 6, and a jack 14 is provided inside the telescopic slot 13. Two teeth 16 are fixedly installed at the bottom of the pressing block 7, and a counterbore 15 is provided in the pressing block 7 between the two teeth 16. A first fixing ring 17 is fixedly installed at the bottom of the operating rod 8, and a pulling block 18 is fixedly installed at the top of the operating rod 8. A second fixing ring 20 is also fixedly installed on the operating rod 8 between the first fixing ring 17 and the pulling block 18. The bottom of the operating rod 8 is rotatably installed in the counterbore 15 through the first fixing ring 17, and the pulling block 18 is placed between the two side plates 9. A compression spring 19 is sleeved on the operating rod 8 between the operating rod 8 and the second fixing ring 20.
