Description

Technical Field

[0001] The utility model belongs to the field of cooler equipment, and particularly relates to a waste steam cooler with a filtering structure. Background Art

[0002] A waste steam cooler is a device for treating waste steam. At present, there are some drawbacks in the existing waste steam coolers. First of all, due to the lack of a filtering structure, impurities in the waste steam, such as solid particles, chemical precipitates, etc., may enter the cooler along with the steam and gradually accumulate in parts such as cooling pipes and heat exchange surfaces, resulting in blockage, reducing the cooling efficiency, and even damaging the cooler. These impurities may come from the residues in the disinfection and inactivation process of the fermentation tank or the dirt in the pipeline. The conventional countermeasure is to regularly clean and maintain the cooler, such as flushing with high-pressure water flow or cleaning with chemical cleaning agents. However, this method has drawbacks. Frequent cleaning will increase the maintenance cost and downtime of the equipment, affecting the production efficiency. Moreover, the chemical cleaning agent may corrode the materials of the cooler, shortening the service life of the equipment. Therefore, a new structure is needed to solve the above technical problems. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a waste steam cooler with a filtering structure to solve the problems put forward in the above background art.

One end of the spray head away from the filter frame is connected to a high-pressure water supply device through a hose. When in use, the spray heads can also regularly clean the filter screens and the activated carbon layer to prevent the filtration efficiency from decreasing due to excessive accumulation of impurities.

[0022] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a waste steam cooler with a filtering structure, including: a cooler body 100 and a filtering component. On the outer surface of the cooler body 100, there are an air inlet pipe 110, a liquid discharge pipe 120, and support legs 130. Support legs 130 are installed on the lower side of the outer surface of the cooler body 100. An air inlet pipe 110 and a liquid discharge pipe 120 are installed on the upper side surface of the cooler body 100. A connecting pipe is installed on the outer surface of the cooler body 100 through the air inlet pipe 110. One end of the connecting pipe away from the air inlet pipe 110 is installed with a filtering component through a connecting flange. The filtering component includes: a filtering frame 200, a pipe one 210, a pipe two 220, a collecting pipe 240, a filtering element 260, and a spray head 250. A pipe one 210 and a pipe two 220 are respectively installed on the front side surface and the rear side surface of the filtering frame 200. A filtering element 260 is installed inside the filtering frame 200. A spray head 250 is installed on the upper side surface of the filtering frame 200. A collecting pipe 240 is installed on the lower side surface of the filtering frame 200.

[0023] Please refer to Figures 1 to 5 , as the first embodiment of the present utility model: Two support legs 130 are symmetrically installed on the lower side surface of the outer surface of the cooler body 100. A liquid discharge pipe 120 is installed on the front side of the outer surface of the cooler body 100. An air inlet pipe 110 is installed on the rear side of the outer surface of the cooler body 100. One end of the air inlet pipe 110 away from the cooler body 100 is installed with an L-shaped connecting pipe through a connecting flange;

[0024] One end of the connecting pipe away from the cooler body 100 is connected to the front end of the pipe one 210 through a connecting flange. The pipe one 210 and the pipe two 220 have the same structure. Valves are provided at the connection points of the pipe one 210, the pipe two 220 and the filtering frame 200. One end of the pipe two 220 away from the filtering frame 200 is connected to the disinfection and inactivation steam supply end of the fermentation tank through a connecting flange;

[0025] The filtering element 260 includes: a first filter screen, a second filter screen, a third filter screen, and an activated carbon layer. A box door 230 is hinged to the left side surface of the filtering frame 200 through a lock and damping seal. A first filter screen is installed on one side of the inner wall of the filtering frame 200 close to the pipe one 210. To the right of the first filter screen, a second filter screen, a third filter screen, and an activated carbon layer are successively installed through the inner wall of the filtering frame 200;

[0026] When in use, when it is necessary to cool the disinfected and inactivated steam of the fermenter first, first supply air into the inside of the filter box 200 through the first pipeline 210, then enter the second pipeline 220 through the filter box 200, then enter the connecting pipe from the second pipeline 220, and finally supply air to the air inlet pipe 110 of the cooler body 100 through the connecting pipe, so as to perform the cooling and filtering operation (the cooler body 100 is a prior art, and its model can be selected from the existing equipment on the market, as long as it meets the use requirements, and its specific working principle and structure will not be elaborated here). When the disinfected and inactivated steam enters the inside of the filter box 200 through the first pipeline 210, it will first be filtered by the first filter screen, the second filter screen, the third filter screen and the activated carbon layer inside the filter element 260 in sequence, and finally discharged through the above steps. After the filter element 260 is used for a period of time and washed by the spray head 250 many times, the user can open the door 230 on the left surface of the filter box 200 to replace and maintain the filter element 260 inside the filter box 200. Since the filter element 260 is installed inside the filter box 200 during use, in combination with the first pipeline 210 and the second pipeline 220, a multi-stage filtration channel can be formed. When the waste steam passes through different filtration areas, different filter elements 260 can filter impurities of different sizes and properties step by step, greatly improving the filtration accuracy and efficiency.

[0027] Please refer to Figures 1 to 5 As the second embodiment of the present invention: the mesh diameter of the first filter screen is larger than the mesh diameter of the second filter screen, the mesh diameter of the second filter screen is larger than the mesh diameter of the third filter screen. A plurality of spray heads 250 are uniformly installed through the left and right edges of the upper surface of the filter box 200 respectively. Every two spray heads 250 are arranged between the first filter screen, the second filter screen, the third filter screen and the activated carbon layer. One end of the spray head 250 away from the filter box 200 is connected to the high-pressure water supply equipment through a hose;

[0028] The lower surface of the filter box 200 is designed to be open, and a collecting pipe 240 is installed at the opening on the lower side of the filter box 200. A one-way valve is arranged inside the collecting pipe 240;

[0029] When in use, after the filter element 260 has been used for a period of time, the user can turn on the water supply device connected to the nozzle 250 to cause the nozzle 250 to flush the first filter screen, the second filter screen, the third filter screen and the activated carbon layer inside the filter element 260. After the first filter screen, the second filter screen, the third filter screen and the activated carbon layer inside the filter element 260 are flushed, the flushed water source will fall into the collection pipe 240 at this time, and then the valve inside the collection pipe 240 can be opened to drain the sewage. Since the nozzle 250 can also regularly clean the filter screen and the activated carbon layer during use, it can prevent the accumulation of too many impurities from causing a decrease in the filtration efficiency. By spraying high-pressure water flow or cleaning liquid, the impurities attached to the filter medium can be flushed away, restoring the permeability of the filter medium and extending its service life.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
