Description

Technical Field

[0001] The utility model relates to the technical field of beet sugar purification process, in particular to a beet extract settling device. Background Technique

[0002] Beet sugar production is a process of making products such as white granulated sugar and soft white sugar from beets through processes such as juice extraction, purification, evaporation, crystallization, and molasses separation. After the beets are pretreated and shredded, water is used as a solvent to extract the sugar in the beet shreds. This process is called juice extraction. The resulting sugar-containing aqueous solution is extract juice, and the beet shreds after sugar extraction are waste pulp. Even in the juice extraction process, as much non-sugar substances as possible are left in the waste pulp, but there are still non-sugar substances in the extract juice, which will cause difficulties in subsequent processing, affect the quality of sugar, increase the amount of molasses and sugar loss. Therefore, before the extract juice is concentrated and crystallized, it needs to be purified first to achieve the purposes of removing suspended particles in the extract juice, neutralizing the acidity of the extract juice, removing coloring substances, removing non-sugar substances, etc. A settling device is often used in the purification process. In order to reduce the proportion of impurities dissolved in the clear juice as the precipitation time prolongs, and in order to accelerate precipitation, according to the shallow pool theory, generally two groups of settling plates are fixedly installed in the settling device to improve the sedimentation rate of solids in the sugar juice. However, during the sedimentation process, the lower layer accumulates muddy juice, resulting in an increase in impurities in the upper clear juice and not meeting the discharge requirements. And the long-term retention of the clear juice in the settling device will cause the loss of sugar conversion. Therefore, it is necessary to develop a beet extract settling device that can timely clean the lower layer of muddy juice and accelerate the precipitation efficiency. Content of the Utility Model

[0003] Aiming at the above technical problems, the utility model provides a beet extract settling device that can timely clean the lower layer of muddy juice and accelerate the precipitation efficiency, so as to solve the problems that in the existing sedimentation process, the muddy juice accumulated in the lower layer causes an increase in impurities in the upper clear juice and does not meet the discharge requirements, and the long-term retention of the clear juice in the settling device will cause the loss of sugar conversion.

[0004] To solve the above technical problems, a beet extract settling device described in the utility model includes a housing. A heat preservation barrel is fixedly connected to the outside of the housing. An inlet steam pipe is fixedly connected to one side of the heat preservation barrel, and an outlet steam pipe is fixedly connected to the other side. A feed pipe is fixedly connected to one side of the upper part of the housing, and the feed pipe penetrates through the heat preservation barrel. A three-way pipe is fixedly connected to the lower end of the housing. A housing top is fixedly connected above the housing and the heat preservation barrel. A support frame is fixedly connected above the housing top. The housing top is detachably connected to an installation hole cover. A motor is fixedly connected to the support frame. The output end of the motor is fixedly connected to a rotating shaft. The rotating shaft passes through the installation hole cover and extends into the housing. A half sleeve is detachably connected to the rotating shaft, and a plurality of fan blades are slidably connected to the half sleeve.

[0005] Further, a reversing valve is connected to the three-way pipe.

[0006] Further, a heat preservation layer is laid inside the heat preservation barrel.

[0007] Further, a handle is fixedly connected to the installation hole cover.

[0008] Further, a plurality of annular grooves are provided inside the housing, and the fan blades are slidably connected to the housing through the annular grooves.

[0009] Further, a thermometer is installed on the top of the housing.

[0010] The utility model has the following advantages compared with the prior art:

[0011] Through the half sleeve detachably connected to the rotating shaft, the utility model can be easily disassembled and cleaned from the installation hole, and can accelerate the dissolution of substances such as flocculants and the separation of subsequent precipitated substances through the centrifugal force brought by rotation. Through a plurality of fan blades slidably connected to the half sleeve, when the fan blades are pressed, the narrow side end slides downward to form an inclined angle, which can provide support when the flocculant or other substances have not reacted completely. After a certain mass of liquid accumulates in the housing, the narrow side of the fan blade moves downward, and the gap between the fan blade and the half sleeve is increased, so that the exuded juice begins to settle. A heat preservation barrel is connected outside the housing, and a certain temperature can accelerate the settlement of the exuded juice. Description of the Drawings

[0017] The following further describes the utility model with reference to the drawings.

[0018] As Figures 1 to 4A kind of beet leachate sedimentation device shown in the figure includes a housing 1. In order to keep the inside of the housing 1 at the temperature at which the leachate settles fastest, a heat preservation barrel 2 is fixedly connected outside the housing 1. An inlet steam pipe 3 is fixedly connected to one side of the heat preservation barrel 2, and an outlet steam pipe 4 is fixedly connected to the other side. A feed pipe 5 is fixedly connected to one side of the upper part of the housing 1, and the feed pipe 5 penetrates through the heat preservation barrel 2. In order to facilitate separately leading out the clear juice and sediment in the housing 1, a three-way pipe 14 is fixedly connected to the lower end of the housing 1. A housing top 6 is fixedly connected above the housing 1 and the heat preservation barrel 2. A support frame 8 is fixedly connected above the housing top 1. In order to facilitate disassembling, cleaning and replacing the fan blades 12, an installation hole is opened in the middle of the housing top 1, and the installation hole cover 7 is detachably connected to the housing top 6. A motor 13 is fixedly connected to the support frame 8, and the output end of the motor 13 is fixedly connected to a rotating shaft 10. The rotating shaft 10 passes through the installation hole cover 7 and extends into the housing 1. A half sleeve 11 is detachably connected to the rotating shaft 10, and a plurality of fan blades 12 are slidably connected to the half sleeve 11.

[0019] In order to separately discharge the sediment and the clear juice, a reversing valve is connected to the three-way pipe 14.

[0020] In order to reduce heat loss, a heat preservation layer is laid in the heat preservation barrel 2.

[0021] In order to facilitate opening the installation hole cover 7, a handle 9 is fixedly connected to the installation hole cover 7.

If necessary, the mounting hole cover 7 can be opened to add the flocculant. After the sedimentation is completed, the sediment flows out from one end of the tee 14 below the housing 1, and then toggle the reversing valve to make the clear liquid flow out from the other end.
