Description

Effectual baking house of mummification

[ technical field ] A method for producing a semiconductor device

The invention belongs to the technical field of material drying equipment, and particularly relates to a drying room with a good drying effect.

[ background of the invention ]

The material drying device is widely applied to drying processes in the industries of chemical industry, food, medicine, building materials and the like. In the sludge treatment field, mud cakes produced by a sludge dewatering machine freely fall to a mesh-shaped crawler belt after granulation or strip making, and water in the mud cakes on the mesh belt is gradually evaporated through the conveying of a plurality of layers of reciprocating mesh belts, so that materials with lower water content are finally formed and discharged.

The Chinese patent ZL201910748719.6 discloses a peristaltic propulsion type drying device, and the Chinese patent ZL202010175357.9 discloses a material rolling and conveying module and a drying chamber thereof. The two drying rooms adopt the grid platform to carry out conveying and drying on the materials, and the drying effect is good.

At present, the air inlet of the drying equipment (also called "drying room") in the prior art is arranged at the lower part of the drying room, and the air outlet is arranged at the upper part of the drying room, so that the advantages of the drying equipment are as follows: the material is carried from the top to the below, and the material that finally falls the bottom is seen off from the discharge gate, and most material sediment and dust are in the lower part of baking house, and the air outlet is established on baking house upper portion, consequently, a large amount of material sediment and dust can not appear and discharge from the air outlet. However, such drying rooms have the following disadvantages: 1. the hot air with high temperature, low humidity, high wind pressure and high wind speed generated by the heat pump enters the air inlet at the lower part of the drying room. In the drying room, the material layer by layer drops down to the discharge port because the upper feeding port is on the upper layer basically, so the material on the upper layer is in a low-temperature high-humidity state, and high-temperature, low-humidity, high-wind-pressure and high-wind-speed hot wind cannot be obtained in time, so that the temperature cannot be rapidly raised and the drying cannot be performed. 2. The hot air has the characteristic of rising upwards, and the air enters from the lower layer, so that the air can flow upwards towards the fixed air duct more quickly, and the hot air is unevenly distributed. 3. The hot air flows upwards from the bottom, so that the upper surface of the more open material cannot obtain more sufficient air flow, and the evaporation effect is reduced. 4. It is difficult to install a dust filter or collector in the drying room, and even if the dust filter or collector is installed in the heat pump room, it is basically necessary to install a dust filter and collector bag and to perform cleaning periodically. Not only can improve the windage and consume manpower, but also the equipment is suspended during cleaning, thereby causing discontinuous operation of the equipment and increasing the energy consumption.

[ detailed description ] embodiments

As shown in fig. 1 and 2, a drying room 100 with good drying effect has a plurality of material conveying platforms 1 arranged from top to bottom, an air inlet 2 is arranged above the uppermost material conveying platform 1, and an air outlet 3 is arranged below the lowermost material conveying platform 1. The air inlet 2 and the air outlet 3 are both connected to the heat supply module 200, and the heat supply module 200 supplies hot air to the drying room 100 through the air inlet 2. A blower or an air inducing device (not shown) may be disposed at the air outlet 3 for inducing the flow direction of the air and promoting the circulation of the air in the drying room 100.

The drying room 100 of this embodiment is a modular drying room, and specifically refers to a drying room disclosed in chinese patent ZL202010175357.9, except that each layer of material rolling and conveying module of the drying room disclosed in the second embodiment of this document includes two layers of conveying platforms (each layer of conveying platform includes one layer of material rolling and conveying device and one layer of grid platform), each drying module of the drying room of this embodiment only uses one layer of conveying platform, and one layer of conveying platform includes only one layer of grid platform. The specific structure of the material conveying platform 1 of this embodiment is the same as the structure of the strip-stacking push type material conveying platform in the drying device of the material conveying device with the rolling function disclosed in chinese patent ZL 201910838624.3.

The feeding port of the drying room 100 is provided with a material homogenizing mechanism 4 and a strip making forming mechanism 5. The material homogenizing mechanism 4 and the strip-making forming mechanism 5 are both in the prior art, for example, the material homogenizing mechanism 4 can adopt a material conveying device with a screw shaft spreading mechanism disclosed in the Chinese invention patent ZL202010175330.X, and the strip-making forming mechanism 5 can adopt a drier feeding and strip-extruding device disclosed in the Chinese utility model patent ZL 201821064369.9.

The air outlet area where the air outlet 3 in the drying room 100 is located is provided with a dustproof material collecting device.

Dustproof device that gathers materials includes: two inclined

dust collecting plates

61, 62 and a dust-proof plate 63 connecting the two inclined

dust collecting plates

61, 62.

The side edges of the two inclined dust collecting

inclined plates

61 and 62 are connected with the side wall of the drying room 100, and the heights of the inclined plates are arranged from high to low in sequence; the lowermost dust collecting sloping plate 62 is connected to the discharging device 8 of the discharging port 7 of the drying room 100. The dust-proof plate 63 has an upper end connected to the dust collection sloping plate 61 located at a high position and a lower end connected to the dust collection sloping plate 62 located at a low position. The dust guard 63 is vertically straight or the lower end is inclined to the left, so that the slag on the inclined dust collecting plate 61 directly falls on the inclined dust collecting plate 62 without falling on the dust guard 63. The dust-proof plate 63 in this embodiment is a middle-efficiency plate filter.

And the discharging device 8 is a screw conveyor and is used for collecting and conveying the materials which directly fall from the material conveying platform 1 and shake off from the dustproof material collecting device, and finally conveying the materials to the discharging port 7.

The hot air entering from the air inlet 2 passes through the inside of the drying room 100, reaches the dustproof material collecting device, passes through the dustproof plate 63, and is then discharged from the air outlet 3.

The material slag and dust falling from the vent seam of the material conveying platform 1 in the drying room 100 reach the discharging device 8 through the dustproof material collecting device and are discharged from the discharging port 7.

The bottom of the dustproof material collecting device is also connected with a vibrator 9, so that materials collected on the dustproof material collecting device are shaken and conveyed to a discharging device 8, dust is prevented from adhering to a dustproof plate 63, and the continuous ventilation of the dustproof plate 63 is kept.

The working process is as follows: the material passes through a material inlet of the drying room, enters the refining mechanism 4 and the strip making forming mechanism 5, is made to fall after strip making forming, is conveyed to the tail end by the material conveying platform 1 (the material conveying platform 1 in the embodiment is a reciprocating grid platform), is conveyed to the front end by the material conveying platform, falls to the initial end of the next layer of grid platform and is conveyed forwards continuously until the material falls to a spiral conveyor (a discharging device 8) corresponding to the material conveying platform, is conveyed to one end of the drying room through the rotation of a spiral shaft, and finally falls from a material outlet 7. Part of the scattered materials can fall down through the vent seams on the grid platform, and finally, part of the material slag falls on the dust collection

inclined plates

61 and 62 positioned at the bottom ends, and the material slag and the dust on the dust collection

inclined plates

61 and 62 are transferred from the high position to the low position of the inclination under the vibration action of the vibrator 9 and finally reach the spiral conveyor (the discharging device 8) transversely arranged at the tail end. In the rolling and conveying processes, hot air entering from the upper end of the drying room intensively, timely and quickly dries the rolled and formed materials into dry materials with certain hardness, so that the materials are prevented from being stacked into blocks in the conveying and falling processes to influence subsequent drying. After the hot air is filled at a high position, the hot air expands to the bottom layer under the combined action of the air blower for air inlet and the air blower or the induced draft fan for air outlet, and when the hot air reaches the bottom layer, the hot air is wrapped with slag and dust, and the slag and the dust flow back to the air outlet of the heat pump (the heat supply module 200) from the air outlet 3 after passing through the dust guard 63. And under the vibration effect of the vibrator 9, the dust-proof plate 63 also vibrates, so that dust is not easy to attach to the dust-proof plate 63 or material slag or dust attached to the dust-proof plate 63 is shaken off to the dust-collecting sloping plate 62 in time, ventilation of the dust-proof plate 63 is ensured, and finally the material slag or dust can only be discharged through the dust-collecting sloping plate 62 and the screw conveyor (the discharging device 8).

The invention reasonably distributes air volume and heat, so that the rolled and formed materials can quickly absorb heat, dehumidify, dry and harden, and the materials can not be stacked into blocks in the processes of conveying and dropping, thereby striving for larger drying surface area for subsequent drying. The material is blown from the top, so that the air flow on the surface of the material is more direct and violent. The dust filtering and collecting functions are ensured only by arranging the dust filtering device in the drying room, and the process equipment of the subsequent flow can be provided with no dust filtering and collecting device or the great burden is lightened for the process equipment of the subsequent flow. The automatic operation level of the drying equipment can be further improved, the dependence on manpower when the filtering device is cleaned is reduced, the stability and the continuity of operation are improved, and the loss of energy consumption is reduced.

The above description is only an example of the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
