Description

FIELD OF THE INVENTIONThe present invention relates to a portable smokeless cremation device for incinerating infected and non-infected dead animals that use fuels such as wood, briquettes and cow dung cakes. The cremation device uses less amount of fuel, gives out a smokeless flame and heats upto more than 800°C, ensuring complete sterilization to cremate the dead animal.BACKGROUND OF THE INVENTION[1] The cremation of domestic pets, stray animals and animals in agricultural husbandries is a substantial challenge since burning the dead carcass produces offensive smoke and odours generated as a byproduct of burning. It is generally performed in remote locations away from inhabitations where fire is generated for burning the carcass using large amount of natural gas or wood or other fuels.[2] Many types of incinerators have been invented, details of which are as follows: [3] CN205119073U Spontaneous combustion formula experimental animals corpse innocent treatment device: provides a animals corpse innocent treatment device, include: burn burning device, communicate in burn the waste heat recovery device at burning device top and communicate in waste heat recovery device's smoke treatment device, waste heat recovery device includes a condensation chamber and locates the coil pipe of condensation intracavity portion, the one end in condensation chamber is equipped with the cooling water inlet who communicates in the coil pipe, the other end in condensation chamber be equipped with communicate in the insulating tube of coil pipe, smoke treatment device including purify the chamber, communicate in the component is handled to the exhaust port in purification chamber and the flue gas that is used for getting rid of flue gas particles.[4] US4000705A Process for disposing of animal carcasses discloses:The carcass of a dead animal is placed within a heating chamber and a burner disposed at one end of the chamber emits a flame which substantially engulfs the chamber.[5] CN203725476U Innocent treatment equipment for animal carcasses: comprises a cooking device, a smashing device, a concentration adjusting device, a hydrolytic acidulation device, an anaerobic digestion device and drying equipment, wherein a liquid exhaust port of a cooking pot is connected to an oil-water separator; the smashing device comprises a hopper and a smashing machine which are used for receiving and smashing material inside the cooling device; the concentration adjusting device is used for receiving the smashed material in the smashing device and adjusting the concentration; the hydrolytic acidulation device is used for receiving and acidulating the material in the concentration adjusting device.[6] KR20080000207A The incinerator for animal's dead body and waste wood: provided the incinerator as a boiler normally by incinerating waste wood instead of dead bodies of animals. An incinerator for an animal's dead body and waste wood comprises a first combustion chamber, a dust collector, a second combustion chamber, an air pre-heater, a boiler, and a gas filtering device.[7] US20090229500A1 Animal carcass incinerator: An incinerator for burning waste products such as animal carcasses. The incinerator features a rotating combustion chamber with sloping side walls. The sloping side walls cause the waste product to concentrate in the center of the combustion chamber where the product is subjected to the flame of a burner. A hatch is provided in the center of the combustion chamber to allow for easy cleaning of the combustion chamber. [8] The main problem is that all the known equipment's for animal cremation and purification are non-potable and uses high fuels. Moreover, the existing system of body disposal is either electric crematorium which is expensive and has high operating costs due to higher power consumption. The second option is also gas or diesel-fired, which is not widespread due to ritual reasons. [9] The existing traditional process of electrical cremation employs expensive, high operating costs, and high-power consumption. Therefore, the people are still hesitant to use electric crematoriums.

[10] We are here disclosing the solution of above problems. The present invention describes novel device, which we have named as "Portable Cremation Incinerator for Animals" (abbreviated as PCIPA hereafter), which can be used to cremate and sterilize the dead animal bodies and remains thereof. PCIPA can entirely burn the infected as well as non-infected dead animals. The best part is that it can be taken anywhere as per the requirement. Rotary clubs, temples, gurudwaras can easily use it.

[11] The developed device of a moveable cremation system which claims to be using first of its kind technology that involves smokeless cremation despite using fuels such as wood, briquettes and cow dung cakes. It uses less amount of the fuels otherwise required for the cremation and still is eco-friendly because of the technology that uses a combustion air system.

[12] The PCIPA cremation system heats up more than 800 degrees Celsius, ensuring complete sterilization that can be used to cremate the dead animals.

[13] The said system and method are more energy efficient, cost effective and environment friendly. The said method and device are unique in terms of its simplicity, expandability, multiple utility etc.OBJECTS OF THE INVENTION

[14] The main objective of the invention is to provide a portable smokeless device for incinerating infected and non -infected dead animals

[15] Another objective of the invention is to provide a fuel-efficient device using fuels such as wood, briquettes and cow dung cakes and reduce consumption of fuel by half.

[16] Another objective of the invention is ensuring complete sterilization after cremating the dead animal.

[17] These and other features and advantages of the present invention may be incorporated into certain embodiments of the invention and will become more fully apparent from the following description or may be learned by the practice of the invention as set forth hereinafter. The present invention does not require that all the advantageous features and all the advantages described herein be incorporated into every embodiment of the invention.SUMMARY OF THE INVENTION

[18] The present invention discloses an ecofriendly, portable cremation device. It uses a combustion air system which results in complete combustion of fuel leading to smokeless burning, with temperatures rising to more than 1000°C and result in complete sterilization.

[19] This cremation device requires fuel which is almost half the amount of fuel that is required in conventional methods.

[20] The device is placed on a portable cart, comprising of two wheels.

[21] The device comprises of a flat rack container for holding irregular and heavy animals. It has a platform and is open sided on two ends to allow efficient loading of the animal, securing it and transporting it. The platform is made in such a manner that it allows circulation of air and disposal of ashes into a tray which lies underneath the platform. The platform comprises of multiple long cubical bars placed end to end. These cubical bars are made of spheroidal cast iron which gives the platform high strength. The bars are so placed that one corner of the cubical bars lies adjacent to one corner of the other cubical bar, such that there is an air gap between the two corners. This construction allows inlet of primary air from underneath the platform through the air gaps and provides a percentage of the combustion air. The primary air flows uninterrupted into the container and reduces the amount of fuel that is burnt. The construction also allows slipping of ash through the air gap onto the tray beneath the platform.

[22] The platform is supported by an extended girder to allow the device to bear the heavy weight of the dead animal. The multiple hexagonal openings in the web flange of the extended girder act as inlets for the secondary air from the atmosphere to enter the device.

[23] The two side walls of the flat rack container are double walled. The side walls are supported by an extended girder. The extended girder is constructed such that the hexagonal openings in the web flange allow the secondary air entering the gap between the double walls to get heated. The inner side of the double wall has perforations on the upper half. The perforations allow the heated secondary air within the double wall to emerge out and provide a heated environment in the device. The heated secondary air dries up all the moisture of the fuel and also the moisture present in the dead carcass and promotes the fuel and the dried carcass to burn completely with a smokeless flame. Thus, the fuel required is nearly halved. The outer wall of the double wall is insulated so that it does not allow the heat to escape, maintaining the temperature in the device to provide complete sterilization also. Thus, complete disposal of the body is achieved in 10-12 hours including the cooling time.BRIEF DESCRIPTION OF THE DRAWING
