PL71177Y1 - Construction of a movable sieve for emptying of a chamber dryer - Google Patents

Abstract

The subject of the application is the construction of a movable screen to be placed on a metal flange at the bottom of the dryer chamber. There is a movable sieve (3) with a mesh and a cable to lift the sieve on the flange. The sieve has the form of a metal ring (1) with brackets (2) for mounting in the center of the discharge opening (4), which closes the plug with a pull cord. Emptying the chamber after the drying process involves removing the plug using the pull rod and rotating the sieve using the pull rod (7).

Description

PL 71 177 Y1 2 Description of the design The subject of the utility design is the construction of a movable screen for emptying a chamber dryer. The dryer is made in the form of a cylinder with a conical bottom with a metal ring on which a movable sieve is mounted and with a discharge opening. The dryer is filled to a height equal to, min. chamber diameter with moist granular material. Warm air flows through the bed. Emptying the dryer after the drying process was carried out using a movable sieve mounted in the drain cone. Known designs and methods of emptying chamber drying tanks involve the use of valves in the sloping tube bottom, mechanical devices, e.g. screw elevators, or suction systems, e.g., an industrial vacuum cleaner. The purpose of the utility model is to easily empty the dryer tank through the discharge funnel thanks to the use of a movable sieve according to the utility model. The solution according to the utility model is the construction of a sieve placed on a flange in the conical bottom of the chamber. Pouring out granular material involves lifting the sieve with a cable. The movable sieve is rotated and reveals the discharge opening. The problem is lifting the sieve up due to the pressure and friction of the material. The essence of the solution is to use a hole in the middle of the sieve, blocked with a cork, which, when uncovered, causes a spill of material blocking the rotation and allows the sieve to move upwards. A movable sieve according to the utility model allows you to empty the dryer chamber by pulling out the plug with a pull rod to unblock the pour-in and rotating the sieve with a second pull rod revealing the discharge opening. The screen according to the pattern can be easily installed and dismantled in the drying chamber. The sieve 3 consists of a metal flange 1 with a circular outline, the upper part of which is closed with a mesh and has a centrally located ring 4 with a filling hole, which is attached to the flange using four symmetrically located brackets 2, and to the On the inner surface of the flange, there is a rod 7 attached, designed to lift and move the sieve 3. The inlet opening of the ring 4 is closed by a conical metal or rubber plug 5 with a rod 6 for closing and opening the hole. The solution is presented in the attached illustration, in which Fig. 1 shows a movable sieve with a central hole and a stopper in a top view, Fig. 2 in a side view. PL PL PL PL PL PL PL PL PL
