Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of observation windows, in particular to a negative pressure window structure for a cremator. BACKGROUND

[0002] As the core equipment of the cremation industry, the innovation of the cremator technology is crucial. Among them, the development process and current situation of the cremator window are closely related to the progress of the cremation technology.

[0003] Early cremators usually do not have a window structure due to technical limitations. The operator cannot directly observe the cremation process in the furnace and can only estimate the cremation progress by experience and rough estimation of the cremation time. This lack of direct observation has many drawbacks, such as difficulty in accurately controlling the degree of cremation, and easy occurrence of incomplete cremation or over-cremation. Incomplete cremation means that the body is not fully processed, which not only violates the basic requirements of the funeral industry, but also may cause dissatisfaction of the family members; while over-cremation will cause waste of energy and increase operating costs. In addition, the situation in the furnace cannot be observed in real time, and once problems such as abnormal combustion, equipment failure, etc. occur, it is difficult to discover and handle them in time, thereby affecting the normal operation and service life of the cremator. Or the worker opens the furnace door from time to time to observe the situation in the furnace, and the polluted gas, dust, etc. in the furnace will be scattered, worsening the workshop environment.

[0004] With the gradual development of cremation technology, some cremators began to be equipped with windows. However, the existing cremator windows generally face the problem that the window glass is easily affected by adhering substances, which affects the line of sight. During the cremation process, the body burns will produce a large amount of smoke, oil and other combustion by-products. These substances are in gaseous or small particle form under high temperature environment, which are easily attached to the surface of the window glass. Once the window glass is contaminated, the transparency will quickly decrease, making it difficult for the operator to clearly observe the cremation situation in the furnace.

[0005] This blocked line of sight seriously affects the accuracy and efficiency of the cremation operation. For example, when the operator cannot see the burning state of the body in the furnace, it is difficult to accurately adjust the combustion parameters such as air supply, fuel flow, etc., thereby reducing the combustion efficiency, prolonging the cremation time, and further increasing energy consumption. At the same time, it is also not conducive to timely discovery of abnormal conditions in the furnace, such as local fire, furnace body damage, etc., if not handled in time, it may cause more serious safety accidents, threatening the life safety of the operator and the cremation equipment.

[0006] In addition, frequent cleaning of the window glass not only increases the workload and labor intensity of the operator, but also interrupts the cremation process due to cleaning operation, affecting the cremation efficiency. Moreover, during the cleaning process, due to the high temperature state of the window glass, improper operation can easily cause the glass to break, increase the equipment maintenance cost and the frequency of replacing the window, and reduce the overall operation efficiency of the cremation furnace.

[0022] Further description will be made in combination with the drawings and specific embodiments: Embodiment 1 In order to facilitate observation of the situation inside the cremator, and to avoid the setting of glass window leading to the adhesion of foreign matter affecting the observation line of sight, the embodiment provides a viewing window installed on the cremator. The existence of the viewing window makes the cremator communicate with the external environment, and the viewing window is connected with the air pump (such as a streamlined impeller vacuum air compressor), so that the gas output from the air pump enters the viewing window and is discharged at high speed from the inner side wall of the viewing window, using the ejector effect to drive the air in the environment to enter the furnace body from the annular viewing window, thereby avoiding the exhaust of the gas in the cremator while ensuring the observation line of sight.

[0023] As shown in Figure 1 , Figure 2 , in order to achieve the above purpose, the viewing window comprises a flange plate 1, a negative pressure air wall 2, etc. The flange plate 1 is installed at the window hole of the cremator, and the negative pressure air wall 2 is installed on the side of the flange plate 1 away from the cremator. The negative pressure air wall 2 is arranged in an annular structure, and a gas cavity 5 is formed in the inside of the negative pressure air wall 2. At the same time, an annular gas outlet slit 3 is arranged on the inner side of the negative pressure air wall 2, and an air inlet pipe 4 is arranged on the outer side of the negative pressure air wall 2. The air inlet pipe 4 is connected with the output end of the air pump through a pipeline. By using the structural characteristics of the gas cavity 5, i.e. the design of wide air inlet and narrow gas outlet slit 3, the gas entering the gas cavity 5 is accelerated and discharged from the gas outlet slit 3, and drives the air in the environment to pass through the flange plate 1 and enter the cremator. The gas outlet slit 3 is arranged along the height direction of the negative pressure air wall 2, and the opening is directed towards the cremator, so that the high-speed flowing gas flows into the cremator.

[0024] As shown in Figure 1 , Figure 2 , in addition, the diameter of the inner side of the negative pressure air wall 2 away from the flange plate 1 at one end is smaller than that at the other end, and the gas outlet slit 3 is arranged in an annular structure at the end of the negative pressure air wall 2 away from the flange plate 1. Therefore, under the condition that the gas is discharged at high speed from the gas outlet slit 3, a negative pressure environment is formed in the negative pressure air wall 2, which further drives the external gas to flow into the negative pressure air wall 2 and into the cremator.

[0025] Embodiment 2 As shown in Figure 3 , Figure 4 , Figure 5As shown, on the basis of example 1, because the gas outlet slit 3 is relatively narrow, and the environment in the workshop is poor, impurities mixed in the gas are easily trapped in the air cavity 5, and even block the gas outlet slit 3. In order to facilitate the staff to clean the impurities in the negative pressure wind wall 2, the negative pressure wind wall 2 in this embodiment includes an upper side wall 21 and a lower side wall 22 which are both arc-shaped structures, and the upper side wall 21 and the lower side wall 22 are connected by bolts, and at the same time, the inner edges of the upper side wall 21 and the lower side wall 22 form the gas outlet slit 3, so that the state of the gas outlet slit 3 can be changed by disassembling the upper side wall 21 and the lower side wall 22, and the air cavity 5 is exposed, and then the impurities accumulated in the negative pressure wind wall 2 are cleaned.

[0026] Specifically, the outer diameters of the upper side wall 21 and the lower side wall 22 are equal, and the inner diameter of the upper side wall 21 is smaller than that of the lower side wall 22, and the inner edge portions of the upper side wall 21 and the lower side wall 22 overlap, that is, the inner edge portion of the upper side wall 21 covers the inner edge of the lower side wall 22, thereby forming the gas outlet slit 3 and controlling the gas to flow into the cremator after being output along the gas outlet slit 3.

[0027] In order to realize the detachable connection of the upper side wall 21 and the lower side wall 22, the outer edges of the upper side wall 21 and the lower side wall 22 are provided with ear plates, and the upper and lower opposite ear plates are connected by bolts, and at the same time, a sealing layer is provided at the contact surface of the outer edges of the upper side wall 21 and the lower side wall 22.

[0028] In addition, a splicing arc groove 23 is provided at the opposite inlet pipe 4 of the upper side wall 21 and the lower side wall 22, the inlet pipe 4 is fixedly connected with the splicing arc groove 23 of the lower side wall 22, and a sealing layer is provided between the splicing arc groove 23 of the upper side wall 21 and the inlet pipe 4. Example 3 As shown in Figure 6 , Figure 7 on the basis of example 2, in order to clean the gas outlet slit 3 in the case of blockage, an arc-shaped cleaning plate 6 is provided at the gas outlet slit 3, the upper end of the cleaning plate 6 is attached to the top of the lower side wall 22, and the bottom of the upper side wall 21 is inserted into the lower end of the cleaning plate 6, so that the cleaning plate 6 is stably installed at the gas outlet slit 3 under the cooperation of the lower side wall 22 and the upper side wall 21, and it is convenient to control the reverse movement of the cleaning plate 6 along the circumference of the gas outlet slit 3, thereby making the impurities blocked in the gas outlet slit 3 separate.

[0029] In order to facilitate the staff to control the movement of the cleaning plate 6, a pull rod 61 is provided at the bottom of the cleaning plate 6, and the direction of the pull rod 61 can be set according to the needs, such as setting the pull rod 61 along the radial direction of the negative pressure wind wall 2. This kind of setting can facilitate the staff to hold the pull rod 61 to control the movement of the cleaning plate 6.

[0030] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations.
