Description

Technical Field

[0001] The utility model relates to the technical field of new energy sources, in particular to an anti-oil preheating device for compound fertilizer coating. Background Art

[0002] The compound fertilizer coating process is a production technology that mixes a variety of fertilizers, plant growth regulators and pesticides in a certain proportion, and then uses a coating agent to wrap them to form a synthetic fertilizer containing multiple nutrients, regulators and pesticides.

[0003] In existing technologies, anti-caking oils are commonly used as a solution to the problem of compound fertilizer clumping during storage and transportation. However, a key pretreatment step in the application of anti-caking oils is heating them to 98°C via steam coils to meet the requirements of subsequent coating. This heating process not only has relatively low thermal efficiency, resulting in slow heat conversion, but also significantly increases steam consumption. Utility Model Content

[0021] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0022] like Figure 1-Figure 7 The anti-oil preheating device for compound fertilizer coating of the present invention includes a preheating box 2, a condensate inlet pipe 1 connected to the inside of the preheating box 2 is provided on the top of the preheating box 2, a communicating port 6 is provided on the top of the preheating box 2, a blind groove 11 is provided on the front and rear inner walls of the communicating port 6, a slide 10 is provided on the left and right inner walls of the blind groove 11, a slider 13 is provided in the slide 10, a rotating shaft 12 rotatably connected to the slider 13 is provided between the two sliders 13, a guide roller 8 is installed on the outer wall of the rotating shaft 12, a spring 9 is provided in the slide 10, one end of the spring 9 is fixedly connected to the side wall of the slider 13 away from the notch of the blind groove 11, and the other end of the spring 9 is fixedly connected to the side wall of the slide 10 away from the notch of the blind groove 11, the guide roller 8 is located outside the blind groove 11 away from the end of the spring 9, and the lateral distance between the two guide rollers 8 forms an anti-oil barrel guide space.

[0023] By providing two communication ports 6 at the top of the preheating box 2, with the two communication ports 6 equally spaced along the front-to-back direction of the preheating box 2, it is convenient for workers to preheat multiple anti-condensation oil drums simultaneously. By providing inclined plates 7 fixedly connected to the inner bottom wall of the preheating box 2 on the left and right inner walls of the preheating box 2, with the front and rear ends of the inclined plates 7 respectively fixed to the front and rear inner walls of the preheating box 2, and the two communication ports 6 located between the two inclined plates 7, the use of the two inclined plates 7 can reduce the amount of condensed water required for preheating the anti-condensation oil drums, allowing the condensed water to more quickly contact and exchange heat with the anti-condensation oil drums after entering the preheating box 2. By providing a guide groove 14 located between the two communication ports 6 on the inner bottom wall of the preheating box 2, a water outlet 5 compatible with the guide groove 14 is provided on the front side wall of the preheating box 2, a water outlet pipe 4 connected to the water outlet 5 is fixedly connected to the front side wall of the preheating box 2, and a water valve 3 is installed on the water outlet pipe 4. The guide groove 14, the water outlet pipe 4 and the water valve 3 can be used to discharge the condensed water that has been heated in the preheating box 2 after the anti-condensation oil barrel is preheated. By making the lateral width of the guide groove 14 larger than the lateral width of the bottom of the guide groove 14, the front and rear ends of the guide groove 14 are respectively aligned with the front and rear inner walls of the preheating box 2, which can accelerate the flow rate of the condensed water discharge and improve drainage efficiency.

[0024] Combined with attachment Figure 1-7 It can be seen that the method of using the present invention is as follows: first, connect the condensate inlet pipe 1 to the condensate pipeline of other processes, so that the condensate (above 80 degrees) generated during the production of other processes can enter the preheating box 2 through the condensate inlet pipe 1, and then put the anti-condensation oil barrel into the anti-condensation oil barrel guide space in the connecting port 6, so that the front and rear side walls of the anti-condensation oil barrel are in contact with the front and rear guide rollers 8 respectively. In this process, the anti-condensation oil barrel will push the guide roller 8 to move in the blind groove 11 toward the bottom of the blind groove 11, and make The rotating shaft 12 pushes the slider 13 to move in the slide groove 10, so that the slider 13 compresses the spring 9, and then controls the anti-caking oil barrel to move downward, so that the bottom of the anti-caking oil barrel contacts the bottom wall of the preheating box 2, and drives the guide roller 8 to rotate on the rotating shaft 12 to guide the anti-caking oil barrel. Then, the anti-caking oil barrel is preheated to above 70 degrees and then transported to the oiling process. After the preheating of the anti-caking oil barrel is completed, the water valve 3 is opened to discharge the water in the preheating box 2 from the water outlet pipe 4 through the guide groove 14 and the water outlet 5.
