Technical Field

[0001] The utility model relates to the technical field of sewage treatment for stem washing machines, and specifically, to an on-line purification treatment and recycling system for the sewage of a stem washing machine used in tobacco equipment. Background Art

[0002] Tobacco stem washing refers to the process of cleaning tobacco stems during the tobacco leaf processing. Tobacco stems are the stem parts of tobacco, containing certain impurities and bad odors, which affect the quality of tobacco products. Through the stem washing process, impurities, odors and some harmful substances in the tobacco stems can be removed, the taste and aroma of the tobacco leaves can be improved, and at the same time, the content of tar and harmful components can be reduced.

[0003] However, since the tobacco stems contain sundries such as dust, sediment and hemp hairs, the impurity content continuously increases during the process of the stem washing machine treating the tobacco stems, and the water quality of the process water will continue to deteriorate, resulting in uneven back penetration of the tobacco stems under the same process parameters, and a lot of water scale adhering to the internal coil pipes of the equipment, leading to fluctuations in subsequent processing parameters.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figure 1 - Figure 2 , the embodiment of the present utility model provides an on-line purification treatment and recycling system for the sewage of a stem washer for tobacco equipment, including: a stem washer 1.

[0020] Among them, Figure 1 - Figure 4 As shown, a circulating water tank 6 is installed on the top of the stem washer 1, and the circulating water tank 6 can circulate the cleaning water in the stem washer 1 for flushing operation. The water outlet of the stem washer 1 is connected to the lifting pump 2 through a pipe body, and the water outlet of the lifting pump 2 is connected to the medium separator 3 through a pipe body. The water outlet of the medium separator 3 is connected to two secondary treatment tanks 4 through a pipe body, and the water outlet of the secondary treatment tank 4 is connected to the tertiary treatment tank 5 through a pipe body. A clean water discharge valve 9 is installed at the bottom of the tertiary treatment tank 5, and a first filter layer 11 is provided inside the secondary treatment tank 4, and a second filter layer 12 is provided inside the tertiary treatment tank 5.

[0021] When in use, the sewage generated by the stem washer 1 is transported to the medium separator 3 through the lifting pump 2, which is used to preliminarily separate large particles of impurities in the sewage and discharge the impure sewage into the ditch. Subsequently, the sewage after the preliminary separation enters two secondary treatment tanks 4, and the smaller particles are further removed through the first filter layer 11 in the tank. The sewage after the secondary treatment flows into the tertiary treatment tank 5, and the tertiary treatment tank 5 finely filters the sewage through the second filter layer 12.

[0022] Further, see Figure 2 The bottom of the medium separator 3 is connected to a first sewage outlet 7, and the bottom of the tertiary treatment tank 5 is connected to a second sewage outlet 8. The impurity sewage accumulated after the medium separator 3 and the tertiary treatment tank 5 filter the sewage can be discharged to the outside through the first sewage outlet 7 and the second sewage outlet 8.

[0023] In this embodiment, Figure 3 and Figure 4 As shown, the first filter layer 11 is an activated carbon filter layer, and the second filter layer 12 is a 304 stainless steel filter mesh. The activated carbon filter layer can process tiny solid impurities such as tobacco leaf fragments and dust in sewage, and absorb the odor therein at the same time. The second filter layer 12 is a 304 stainless steel filter mesh with a filtration grade of 50μm, which can intercept and filter the mud, tobacco leaf fragments and dust in the tobacco stems.

[0024] like Figure 2 and Figure 3 As shown, in order to facilitate the backwashing operation in the two secondary treatment tanks 4, the tops of the two secondary treatment tanks 4 are connected with backwashing valves 10. When the backwashing operation is performed, the backwashing valve 10 is opened and the water channels of other water inlet units are closed.

[0025] Specifically, a pressure gauge 13 is installed on the top of the tertiary treatment tank 5, and the pressure gauge 13 can be used to monitor whether the tertiary treatment tank 5 is working normally. When the pressure is too high, it is convenient for the operator to determine whether the second filter layer 12 is blocked by impurities.

[0026] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: the utility model filters and purifies the sewage generated by the stem washer 1 through an external sewage filtration system at the cleaning box of the stem washer 1, and the sewage generated flows into the lifting pump 2 through the outlet pipe of the stem washer 1.

[0027] Among them, the lifting pump 2 transports the sewage to the medium separator 3, which is used to preliminarily separate large particles of impurities in the sewage and discharge the impure sewage into the ditch. Subsequently, the sewage after the preliminary separation enters the two secondary treatment tanks 4, and further removes smaller particles through the first filter layer 11 in the tank. The sewage after the secondary treatment flows into the tertiary treatment tank 5, and the tertiary treatment tank 5 finely filters the sewage through the second filter layer 12, and finally discharges the purified water through the clean water discharge valve 9 at the bottom. The treated water can then be re-processed through the stem washing machine 1 for tobacco stem washing operations or directly discharged. The online treatment of the sewage from the stem washing machine 1 reduces the scale accumulation phenomenon in the coil inside the stem washing equipment and reduces the environmental pollution caused by sewage discharge.

[0028] Parts not involved in the present invention are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
