Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas recovery, and relates to a flat conveying waste gas collection device for a cooling granulator. Background Art

[0002] The steel belt cooling granulator is also called a belt cooling granulator, a rotary steel belt granulator, a melting granulator, a rotary belt cooling and forming granulator, etc. According to the viscosity range of the material in the molten state, the molten liquid is evenly distributed on the steel belt moving at a constant speed below it through a special cloth device. Under the cooling action of the continuous spraying device arranged below the steel belt, the material is cooled and solidified during the movement and conveying process, so as to achieve the purpose of granulation and forming. After cooling and granulation, it can be directly packaged.

[0003] The existing Chinese utility model patent with the publication number of CN207237915U, a steel belt type cooling granulator for producing guanidine nitrate, includes a machine shell. A driving roller is connected to the left side inside the machine shell, a driven roller is connected to the right side inside the machine shell. A steel belt is connected between the driving roller and the driven roller. A pressure roller is arranged on one side above the steel belt, a sleeve is arranged on the other side of the steel belt. A cavity layer is arranged inside the sleeve. An air outlet is arranged above the machine shell. An exhaust fan is arranged inside the air outlet. The bottom of the sleeve is respectively provided with a water inlet and a water outlet. A water tank is arranged on the left side inside the machine shell. A water pump is arranged inside the water tank. The water pump is communicated with the water inlet through a water pipe. The water outlet is communicated with the water tank through a water pipe. A feeding plate is connected to the left side of the machine shell.

[0004] The existing technology has the following technical defects:

[0005] In the above technical solution, during the cooling and conveying process, the machine shell covers the steel belt above, but the machine shell is in a planar shape. During the steel belt conveying process, water vapor, waste gas or other oily substances will be generated during the cooling of the material. The water vapor and oily substances will accumulate and cool into water droplets or oil droplets on the top or side wall of the shell. If the accumulation is too much, it will drip on the surface of the material, thus affecting the quality of the material. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the existing technology and provide a flat conveying waste gas collection device for a cooling granulator.

[0007] The flat conveying waste gas collection device for a cooling granulator described in the utility model includes a machine body, and a protective cover is arranged on the machine body. The protective cover is arc-shaped. Side supports are arranged on both sides of the protective cover. Oil collecting grooves are arranged on the side supports. Scraping oil components are arranged in the oil collecting grooves. An oil collecting pipe is arranged below the oil collecting grooves. A plurality of smoke collecting pipes are arranged on the top of the protective cover.

[0008] Working Process or Working Principle:

[0009] During operation, the materials are cooled and conveyed on the steel belt of the machine body. The flue gas generated during the cooling process is prevented from overflowing into the workshop through the protective cover, causing discomfort to personnel. The flue gas is discharged through the smoke collecting pipe, and the condensate adhering to the protective cover will slide down along the arc to the oil collecting tank for collection.

[0010] The described oil scraping assembly includes a guide groove and a sliding groove arranged on the oil collecting tank. A moving block is slidably connected in the guide groove and the sliding groove. A scraping plate adapted to the oil collecting tank is fixedly connected to the moving block. The staff drives the scraping plate to move in the oil collecting tank by moving the moving block, thereby accelerating the convergence of the oil to the oil collecting pipe.

[0011] A handle is provided at the bottom of the moving block, which is beneficial for the staff to move the scraping plate.

[0012] The oil collecting tank is in an inverted triangular shape, and the oil collecting pipe is arranged at the top corner of the oil collecting tank. The inverted triangle shape enables the oil at both ends to slide down along the slope and concentrate at the top corner, and then it is collected through the oil collecting pipe.

[0013] The side support is fixedly connected to the machine body through a support frame.

[0014] The connection between the smoke collecting pipe and the protective cover is rounded, and the condensate on the wall of the smoke collecting pipe can slide into the oil collecting tank through the rounded corner.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] The present utility model can collect the condensed liquid droplets, avoid long-term accumulation and dropping to contaminate the materials, thereby ensuring the production quality of the materials. Description of the Drawings
