Description

Technical Field

[0001] This utility model relates to the field of hydrogenation catalyst processing technology, and in particular to a device for cleaning slurry from a settling tank. Background Technology

[0002] The treatment of hydrogenation catalyst slurry in settling tank is an important process. Settling tank is mainly used to separate catalyst from liquid products. In the hydrogenation process, after the catalyst and reactants are mixed, they are separated in the settling tank in order to recover the catalyst and further process the liquid products. In the settling tank, the catalyst particles, due to their high density, will settle to the bottom of the tank, while the liquid will rise to the upper layer. The slurry after settling usually contains unreacted catalyst particles and some solid impurities.

[0003] When treating slurry, it is necessary to recover the catalyst particles in the slurry to reduce catalyst waste. In the existing technology, the poor fluidity of the slurry makes it impossible to effectively recover the catalyst particles, thereby reducing the recovery effect of the catalyst particles. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as poor fluidity of slurry, which makes it impossible to effectively recover catalyst particles from the slurry and thus reduces the recovery effect of catalyst particles. Therefore, this invention proposes a device for cleaning slurry in settling tanks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a device for cleaning slurry from a sedimentation tank, including an open cylinder with a support mechanism connected to its bottom end. A sealing plate is connected to the opening of the open cylinder, and a discharge pipe is connected to the sealing plate. A geared motor is fixedly connected to one end of the open cylinder, and the output end of the geared motor extends into the open cylinder and is fixedly connected to a stirring component. A liquid injection pipe and a feed pipe are connected to the upper end of the open cylinder. Several activated carbon particles are disposed inside the open cylinder, and a filter mechanism is connected to the sealing plate.

[0007] Preferably, the support mechanism includes a base plate, a fixing plate fixedly connected to the upper end of the base plate, a groove formed at the upper end of the fixing plate, a fixing shaft fixedly connected to the groove, a connecting plate rotatably connected to the fixing shaft, one end of the connecting plate fixedly connected to the bottom end of the open cylinder, a support plate fixedly connected to the upper end of the base plate, the support plate contacting the bottom end of the open cylinder, an electric telescopic rod rotatably connected to the support plate, and the telescopic end of the electric telescopic rod rotatably connected to the bottom end of the open cylinder.

[0008] Preferably, the upper end of the support plate has a notch, which cooperates with the open cylinder.

[0009] Preferably, a flow meter is connected to the injection tube.

[0010] Preferably, the filtration mechanism includes a ring that cooperates with the open cylinder. A plurality of fixed rods are connected at equal intervals along the axial direction on the ring, and one end of each fixed rod is fixedly connected to the sealing plate. A filter screen is fixedly connected to the ring.

[0011] Preferably, the ring and the plurality of fixing rods are an integral structure.

[0012] The device for cleaning slurry in a settling tank proposed in this utility model has the following advantages:

[0013] Solvent oil is introduced into the open cylinder through the injection pipe. After the geared motor is started, it drives the agitator to rotate. The rotation of the agitator agitates the solvent oil, slurry and activated carbon particles. After the solvent oil and slurry are mixed, the viscosity of the slurry is reduced and the fluidity is increased, so that the catalyst particles in the slurry can better contact the activated carbon particles, thereby improving the separation effect of the catalyst particles.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1: Refer to Figure 1-3 A device for cleaning slurry in a sedimentation tank includes an open cylinder 1, a support mechanism 2 connected to the bottom end of the open cylinder 1, a sealing plate 3 connected to the opening of the open cylinder 1, a discharge pipe 4 connected to the sealing plate 3, a geared motor 5 fixedly connected to one end of the open cylinder 1, the output end of the geared motor 5 extending into the open cylinder 1 and fixedly connected to a stirring component 6, a liquid injection pipe 7 connected to the upper end of the open cylinder 1, a flow meter 8 connected to the liquid injection pipe 7, a feed pipe connected to the upper end of the open cylinder 1, a number of activated carbon particles 9 disposed inside the open cylinder 1, and a filter mechanism 10 connected to the sealing plate 3.

[0021] Work process:

[0022] The slurry is introduced into the open cylinder 1 through the feed pipe. The activated carbon particles 9 are located inside the open cylinder 1. The solvent oil is introduced into the open cylinder 1 through the injection pipe 7. The flow meter 8 measures the introduced solvent oil. After the reduction motor 5 is started, it drives the agitator 6 to rotate. After the agitator 6 rotates, it stirs the solvent oil, slurry and activated carbon particles 9. After the solvent oil and slurry are mixed, the viscosity of the slurry is reduced and the fluidity is increased, so that the catalyst particles in the slurry can better contact the activated carbon particles 9, thereby improving the separation effect of the catalyst particles.

[0023] After stirring for a set time and then allowing it to stand for a set time, open the discharge pipe 4. The slurry in the open cylinder 1 is discharged from the discharge pipe 4. The filter mechanism 10 filters the activated carbon particles 9 to prevent the activated carbon particles 9 from being released from the discharge pipe 4.

[0024] Example 2: In Example 1, the activated carbon granules 9 need to be replaced after a period of use. It is inconvenient to pour out the activated carbon granules 9 from the open cylinder 1. Refer to... Figure 2-3In another preferred embodiment of this utility model, the difference from embodiment 1 is that the support mechanism 2 includes a base plate 21, a fixing plate 22 is fixedly connected to the upper end of the base plate 21, a groove is formed at the upper end of the fixing plate 22, a fixing shaft 23 is fixedly connected to the groove, a connecting plate 24 is rotatably connected to the fixing shaft 23, one end of the connecting plate 24 is fixedly connected to the bottom end of the open cylinder 1, a support plate 25 is fixedly connected to the upper end of the base plate 21, the support plate 25 contacts the bottom end of the open cylinder 1, and a notch is formed at the upper end of the support plate 25, which is in contact with the bottom end of the open cylinder. In conjunction with the support plate 25, an electric telescopic rod 26 is rotatably connected to the support plate 25. The telescopic end of the electric telescopic rod 26 is rotatably connected to the bottom end of the open cylinder 1. When the activated carbon particles 9 in the open cylinder 1 are taken out, the sealing plate 3 is removed, the opening of the open cylinder 1 is opened, and after the electric telescopic rod 26 is started, it pushes the open cylinder 1 upward. The open cylinder 1 drives the connecting plate 24 to rotate. The connecting plate 24 rotates around the fixed shaft 23, and the opening of the open cylinder 1 tilts downward. The activated carbon particles 9 in the open cylinder 1 fall from the opening, making it convenient to pour out the activated carbon particles 9 in the open cylinder 1.

[0025] Example 3: In Example 1, when the slurry is discharged from the discharge pipe 4, the activated carbon particles 9 are easily released along with the slurry. (Refer to...) Figure 4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the filter mechanism 10 includes a ring 102, which cooperates with the open cylinder 1. Several fixed rods 101 are connected at equal intervals along the axial direction on the ring 102. The ring 102 and the fixed rods 101 are an integral structure. One end of each fixed rod 101 is fixedly connected to the sealing plate 3. A filter screen 103 is fixedly connected to the ring 102. The fixed rods 101 fix the ring 102, and the ring 102 fixes the filter screen 103. The filter screen 103 filters the activated carbon particles 9 to prevent the activated carbon particles 9 from being released with the slurry.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
