Description

TECHNICAL FIELD [0001] The present invention relates to a method for controlling combustion temperature in an animal husbandry apparatus and an animal husbandry apparatus,

The present invention relates to a method for controlling the combustion temperature in a zoo animal facility (animal cremation facility) and an animal husbandry facility.

In recent years, in Japan, many people are raising a pet about the same level of affection as a family. Accordingly, even when the animal is condemned, there are cases where the same makeup and funeral are performed as in humans. The present applicant has been working on the development of a facility for animal littering for many years (for example, Patent Document 1).

[0003] In such an animal carcass, there has been known a method of injecting fuel such as gas or petroleum as in the case of cremation of a human body, igniting self-combustion (self-combustion) in a predetermined temperature range A process of burning is performed until it is ashes. However, in an animal carcass having a large amount of oil, the combustion temperature rises to a considerable temperature (for example, 1000 ° C) or more during self-combustion, so that a burden is imposed on the cosmetic equipment, Oxygen deficiency may cause incomplete combustion, resulting in the occurrence of severe smoke. For example, when refractory bricks for refilling are used, it is preferable to burn at a temperature of 1200 ° C at the maximum. Further, in order to solve the oxygen deficiency, it is preferable to use an expensive blower or high-concentration oxygen, but it becomes expensive equipment.

In order to avoid such a situation, a facility is constructed using expensive refractory bricks to make the equipment self-combusted at a high temperature of 2000 ° C or higher (Patent Document 2), and incomplete combustion prevention devices, oil absorption devices, And a defensive device such as an absorption device.

However, since a device installed in a cosmetic facility for a person becomes very expensive (in some cases, the cost is higher than that of a cosmetic facility), it is a realistic measure to install these devices on a cosmetic device of an animal carcass It is hard to say.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a device capable of performing appropriate temperature control at the time of combustion in an animal husbandry equipment.

In order to achieve the above object, a cosmetic device for an animal carcass according to a first aspect of the present invention includes a combustion chamber for burning an animal carcass, a fuel inflow device for introducing fuel into the combustion chamber, a temperature sensor for measuring a temperature in the combustion chamber, And a cooling water inflow device that compares the combustion temperature measured by the temperature sensor with a preset upper limit combustion temperature to allow mist cooling water to flow into the combustion chamber when the combustion temperature exceeds the upper limit of the combustion temperature.

According to the present invention, when the temperature during combustion of an animal carcass exceeds a predetermined upper limit of combustion temperature, fog-like cooling water is introduced into the combustion chamber to lower the combustion temperature at once.

The operation of the cooling water inflow device may be performed by a person or automatically controlled by a computer. In the case of using a computer, it is preferable to compare the combustion temperature measured by the temperature sensor with a predetermined upper limit combustion temperature, and operate the cooling water inflow device when the combustion temperature exceeds the combustion upper limit temperature.

In the present invention, the term "animal carcass" refers to a pet to which makeup is carried out, for example, mammals such as cows, horses, sheep, goats, pigs, dogs, cats, and monkeys, and reptiles such as lizards, crocodiles, chameleons, do. Among them, the cows, horses, sheep, goats, pigs, large dogs and the like may contain a lot of oil particularly, so that the present invention becomes particularly effective.

Fuel used in combustion includes gas, petroleum, kerosene and the like. In the case of using petroleum as the fuel at this time, existing facilities equipped with two fuel inflow devices in advance are known. These fuel inflow apparatuses are used to introduce a large amount of fuel (main line) at the start of combustion and fine combustion control (continuous line) at the continuation of combustion. In the present invention, since one of them can be used as the cooling water, the addition of a new facility becomes less, and this is a preferable embodiment.

The cooling water includes both liquid water and mist water. However, when liquid water is supplied, it becomes difficult to spread the liquid throughout the combustion chamber, and water as a liquid remains without evaporation, making post-treatment difficult. For this reason, it is preferable to introduce mist-like water.

A method for controlling the combustion temperature in an animal care facility according to a second aspect of the present invention includes a combustion chamber for burning an animal carcass, a fuel inflow device for injecting fuel into the combustion chamber, a temperature sensor for measuring the temperature in the combustion chamber, (1) a starting step of supplying fuel from the fuel inflow device and igniting the animal carcass, (2) a step of starting the ignition of the carcass, and (3) the combustion temperature of the animal carcass is naturally burned in the stagnant self-combustion temperature range, and (3) the combustion temperature of the animal carcass is naturally burned in the stable self-combustion temperature range (4) the combustion temperature of the animal carcass has reached the upper limit of the combustion temperature To it characterized in that it includes a cooling step of flowing the cooling water mist.

The above steps (1) to (4) may be performed by a person or may be controlled by a computer. For example, (1) to (3) may be processed by a person and only (4) may be automatically controlled by a computer.

According to the present invention, when the combustion temperature of the animal carcass is equal to or higher than a predetermined upper limit of the combustion temperature, mist cooling water flows in, so that incomplete combustion can be prevented and a satisfactory combustion state can be maintained.

In the starting step, the timing of inflow of cosmetic fuel and ignition timing can be arbitrarily selected. For example, there are (1) a method in which the ignition is started after the start of inflow of the cosmetic fuel, (2) a method in which the ignition is simultaneously performed with the inflow of the cosmetic fuel, and (3) All of which can be employed.

The stable magnetic burning temperature and the stable magnetic burning temperature range mean a temperature and a temperature range in which an animal carcass can stably burn its own organism without being supplied with fuel from the outside. This temperature (region) can be determined in consideration of factors such as the size of the combustion chamber, the material of the wall constituting the combustion chamber, the kind and size of the animal carcass. For example, when the combustion chamber is composed of general refractory bricks and the number of animal carcasses is about 10 to 40 kg, the stable magnetic burning temperature range is set to about 700 ° C. to 900 ° C. (preferably 800 ° C. to 850 ° C.) .

In the case where the cosmetic fuel is introduced in the initial step, either continuous or intermittent method may be employed.

The upper limit of the combustion temperature means a temperature at which an abnormal situation such as incomplete combustion occurs when an animal carcass is burned at a temperature higher than this temperature to generate graphite and adversely affect cosmetic equipment. The upper limit of the combustion temperature can be determined in consideration of factors such as the size of the combustion chamber, the material of the wall constituting the combustion chamber, the kind and size of the animal carcass. For example, when the combustion chamber is composed of general refractory bricks and the number of animal carcasses is about 10 to 40 kg, the upper limit of the combustion temperature can be set to 900 캜 (preferably 1000 캜).

In the cooling step, the amount of the incoming cooling water is controlled by time control (a method of controlling the amount of cooling water according to time while keeping the inflow amount of cooling water per unit time constant), the number of times control The method of controlling the amount of cooling water according to the number of times), and the pressure control (the method of controlling the amount of cooling water by the high and low pressure of the mist-like cooling water).

According to the present invention, appropriate temperature control at the time of combustion can be performed in a cosmetic installation of an animal carcass.

<Cosmetic equipment (cremation equipment)>

Fig. 1 and Fig. 2 show a bicycle 1 carrying an animal carcass (D) and a cosmetic device 20. Fig. 3 shows a state in which the bogie 1 is brought into the cosmetic device 20. The cart 1 is provided with a dish plate portion 2 for supporting the animal carcass D and a total of four leg portions 3 hanging down from the front, rear, left and right sides on the lower surface side of the dish plate portion 2 Is installed. A wheel 4 capable of moving the carriage 1 along a guide rail 5 is provided at the lower end of each leg portion 3.

The cosmetic plant 20 is provided with a primary combustion chamber 24 and a secondary combustion chamber 22 in which oil as fuel (and air) is introduced into each of the combustion chambers 22 and 24 (Primary burning burner) 10, an auxiliary burner 11, and a secondary burning burner 23 are provided. In the outer wall 17 of the primary combustion chamber 24, a cooling water inflow device (cooling water inflow device) 12 for introducing cooling water in a mist shape is provided. The secondary combustion chamber 22 is also provided with a temperature sensor 15 having a thermocouple for measuring the combustion temperature.

An inlet door 25 capable of opening and closing the primary combustion chamber 24 is installed at the loading port for loading the animal carcass D into the primary combustion chamber 24 by moving in the vertical direction . Blowers 21 and 16 for sending air (oxygen) to the respective combustion chambers 22 and 24 are provided on the upper and side surfaces of the cosmetics facility 20.

A control board (control board) 32 (computer) for controlling the cosmetic device 20 is provided on the side surface (the right side surface in Fig. 2) of the cosmetic device 20. The control board 32 is connected to the temperature sensor 15, each of the burners 10, 11 and 23, the cooling water inflow unit 12 and the blowers 16 and 21, Control the device.

&Lt; Control method of cosmetic equipment >

Next, a temperature control method for burning the carcass D using the cosmetic device 20 configured as described above will be described with reference to Figs. 4 and 5. Fig.

First, as shown in Fig. 3, the animal carcass D to be burned is carried into the primary combustion chamber 24 of the cosmetics facility 20 in a state of being loaded on the car 1. [ Next, initial setting of the combustion method is performed using the control board 32 (S100). In this case, the air flow rate of the air blown by the blowers 16 and 21, the inflow rate and inflow speed of the fuel flowing from each of the burners 10, 11, and 23 and the ON / OFF control, the stable self- And the combustion upper limit temperature T2, the time interval for executing the temperature comparison step, the inflow amount of water from the cooling water inflow unit 28, and the ON / OFF control.

Next, the combustion control operation by the control board 32 is started (S110: start step). Here, the blowers 16 and 21 are driven to ignite while igniting the animal carcass D while injecting fuel from the burners 10, 11 and 23. Subsequently, the animal carcass D is burned while injecting the fuel (S120). Next, the combustion temperature TP in the combustion chamber measured by the temperature sensor 15 and the stable magnetic burning temperature T1 are compared at predetermined time intervals to evaluate whether or not TP &gt; T1 (S130. S120 and S130 Constitute this initial step). The initial step corresponds to the graph shown by the reference numeral A in Fig.

When TP ≥ T1, it is determined that the animal carcass D is in a state where it can continue its own combustion, and the inflow of fuel from the burners 10, 11, and 23 is stopped (S140). Here, the combustion temperature of the animal carcass D becomes a self-combustion step (self-burning step) in which the natural combustion is performed in the stable magnetic burning temperature range T1 to T2. The self-combustion step corresponds to the graph shown by the numeral (B) in Fig.

Next, the combustion temperature TP and the combustion upper limit temperature T2 are compared at predetermined time intervals to evaluate whether or not TP &gt; T2 (S150). Subsequently, the combustion temperature TP and the stable magnetic burning temperature T1 are compared at predetermined time intervals to evaluate whether TP &lt; / = T1 (S160). In step S150, when TP &gt; = T2, mist cooling water flows from the cooling water inflow unit 12 (S170: cooling step, which corresponds to the point indicated by reference character P in Fig. 5). In this cooling step, the combustion temperature TP is estimated to fall from a combustion upper limit temperature T2 to a predetermined temperature (for example, a temperature drop of about 100 to 200 deg. C, and the combustion temperature TP is set to a stable self- T1) of the animal carcass D), so that the combustion of the carcass D is not stopped (digested). When the combustion temperature TP is lower than the stable magnetic burning temperature T1 (TP &lt; T1) in S160 after the inflow of the cooling water (S170) once or plural times, It is regarded that the combustion is finished and the temperature control processing is completed.

As described above, according to the present embodiment, when the combustion temperature TP of the animal carcass D becomes equal to or higher than the predetermined upper limit of the combustion temperature T2, mist cooling water flows in, and incomplete combustion can be prevented A good combustion state can be maintained.
