Abstract
Description
Technical Field
[0001] This utility model relates to the field of concentrator technology, and more specifically, to a spherical concentrator. Background Technology
[0002] Spherical concentrators are mainly used in the pharmaceutical, biological, food, and chemical industries. They are particularly suitable for the concentration and distillation of heat-sensitive materials and the recovery of organic solvents (such as alcohol). For example, they are used in the concentration of liquids, vacuum concentration and crystallization, paste distillation, and alcohol recovery processes in the fields of traditional Chinese and Western medicine, starch sugar, dairy products, and biopharmaceuticals.
[0003] The working principle of the spherical concentrator is based on depressurization concentration technology. By reducing the pressure inside the equipment, the material can be evaporated and concentrated at a lower temperature. At the same time, the stirring device inside the equipment can ensure that the material is heated evenly, improving the concentration efficiency. The evaporated steam is condensed by the condenser and collected in the receiving tank for subsequent processing.
[0004] There are many types of spherical heat exchangers on the market, but most of them only have inlet and outlet pipes on the outer cylinder, lacking a condensate drain pipe. This limits their application to liquid heat exchange media and prevents the use of steam-type heat exchange media. Furthermore, some spherical heat exchangers, while having a condensate drain pipe, lack corresponding limiting components, allowing steam to escape along with the condensate drain pipe, thus affecting the steam heating effect. Therefore, we propose a new type of spherical heat exchanger. Utility Model Content
[0005] The purpose of this invention is to provide a spherical concentrator to address the deficiencies mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A spherical concentrator includes a spherical concentrator body and a concentration tank disposed on the spherical concentrator body. An outer cylinder is fixedly installed on the outside of the concentration tank. A heating medium inlet chamber is disposed between the outer cylinder and the concentration tank. A condensate drain pipe connected to the heating medium inlet chamber is fixedly installed at the bottom of the outer cylinder. A valve is fixedly installed on the condensate drain pipe. A vertical pipe is fixedly installed at the end of the condensate drain pipe. An expansion chamber is disposed on the inner wall of the bottom end of the vertical pipe. A conical cylinder connected to the outside is fixedly installed on the bottom wall of the expansion chamber. A sealing ball is disposed in the expansion chamber. A float is fixedly installed at the top of the sealing ball. A top rod that passes through the conical cylinder and the vertical pipe is fixedly installed at the bottom end of the sealing ball.
[0008] Preferably, the bottom of the outer cylinder is fixedly equipped with a plurality of vertically arranged support legs, and the distance between the bottom end of the vertical tube and the ground is greater than 20cm.
[0009] Preferably, a discharge pipe is fixedly installed at the center of the bottom of the concentration tank, and the discharge pipe extends out of the outer cylinder and is connected to the outside.
[0010] Preferably, an inlet pipe and an outlet pipe are fixedly installed on the left and right sides of the outer cylinder, respectively, and both the inlet pipe and the outlet pipe are connected to the heating medium inlet chamber.
[0011] Preferably, a perforated plate is fixedly installed on the cavity wall at the top position of the expansion chamber, and the perforated plate has a perforated plate structure.
[0012] Preferably, the conical cylinder is in the shape of a hollow frustum, and the size of the sealing ball is adapted to the size of the conical cylinder.
[0013] Preferably, the bottom wall of the heating medium entering the chamber is provided with an inclined surface, which is inclined downward at 5° to 15° toward the side of the condensate drain pipe.
[0014] Preferably, a mechanical seal is fixedly installed on the top cylinder of the concentration tank, a stirring motor is provided on the mechanical seal, a stirring shaft is fixedly installed at the end of the output shaft of the stirring motor, the stirring shaft passes through the mechanical seal and the concentration tank, and stirring blades are fixedly installed on the stirring shaft, the stirring blades being located inside the concentration tank.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This utility model introduces a heating medium into the chamber, allowing for heating operations by introducing different heating media. When the heating medium is steam, the resulting condensate can be discharged from the condensate drain pipe. The sealing ball and float ensure that when the expansion chamber is empty of water, the sealing ball effectively seals the chamber, reducing steam loss. When the expansion chamber contains water, the float causes the sealing ball to rise, at which point it no longer seals the conical cylinder, allowing for normal condensate discharge. This achieves the effect of allowing the introduction of various heating media for heating and facilitating the smooth discharge of condensate.
[0017] 2. This utility model can perform normal stirring operation through the set stirring motor and stirring blades. Through the set push rod, after the concentration is completed, when there is water in the expansion chamber, the push rod moves upward and drives the sealing ball to move upward. At this time, the water can be smoothly discharged outward along the conical cylinder. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-3 This utility model provides a technical solution: a spherical concentrator, including a spherical concentrator body 1 and a concentrator tank 10 disposed on the spherical concentrator body 1. An outer cylinder 11 is fixedly installed on the outside of the concentrator tank 10. A heating medium inlet chamber 111 is disposed between the outer cylinder 11 and the concentrator tank 10. An inlet pipe 18 and an outlet pipe 19 are fixedly installed on the left and right sides of the outer cylinder 11, respectively. Both the inlet pipe 18 and the outlet pipe 19 are connected to the heating medium inlet chamber 111, so as to realize the heating medium can be delivered into the heating medium inlet chamber 111 to realize the heating operation inside the concentrator tank 10.
[0027] Specifically, a condensate drain pipe 2, which is connected to the heating medium inlet chamber 111, is fixedly installed at the bottom of the outer cylinder 11. A valve 20 is fixedly installed on the condensate drain pipe 2, which is used to control the opening and closing operation. A vertical pipe 21 is fixedly installed at the end of the condensate drain pipe 2. An expansion chamber 22 is provided on the inner wall of the bottom end of the vertical pipe 21. A conical cylinder 24, which is connected to the outside, is fixedly installed on the bottom wall of the expansion chamber 22. A sealing ball 25 is provided inside the expansion chamber 22. A float 26 is fixedly installed at the top of the sealing ball 25. A top rod 27, which passes through the conical cylinder 24 and the vertical pipe 21, is fixedly installed at the bottom of the sealing ball 25. When the float 26 comes into contact with water, it is used to drive the sealing ball 25 to float up. After water accumulates in the expansion chamber 22, the sealing ball 25 floats up, and the accumulated water can be discharged normally.
[0028] In this embodiment, a plurality of vertically arranged support legs 12 are fixedly installed at the bottom of the outer cylinder 11, and the distance between the bottom end of the vertical tube 21 and the ground is greater than 20cm, so that the support legs 12 can be used for support operation.
[0029] Specifically, a discharge pipe 13 is fixedly installed at the bottom center of the concentration tank 10. The discharge pipe 13 extends out of the outer cylinder 11 and is connected to the outside. The discharge pipe 13 is connected to an external pipeline with a valve for subsequent discharge and other operations.
[0030] Furthermore, a perforated plate 23 is fixedly installed on the cavity wall at the top position of the expansion chamber 22. The perforated plate 23 has a perforated plate structure and is used to ensure the normal flow of water, while also limiting the upward distance of the float 26.
[0031] In addition, the cone 24 is in the shape of a hollow frustum, and the size of the sealing ball 25 is adapted to the size of the cone 24, so that the sealing ball 25 can achieve a normal sealing effect after it abuts against the bottom wall of the cone 24.
[0032] It is worth noting that an inclined surface 3 is provided on the bottom wall of the heating medium entering the chamber 111. The inclined surface 3 is set at a downward angle of 5° to 15° towards the side of the condensate drain pipe 2, so that the condensate at the bottom of the heating medium entering the chamber 111 flows more smoothly towards the side of the condensate drain pipe 2.
[0033] It is worth noting that a mechanical seal 14 is fixedly installed on the top cylinder of the concentration tank 10. A stirring motor 15 is installed on the mechanical seal 14. A stirring shaft 16 is fixedly installed at the end of the output shaft of the stirring motor 15. The stirring shaft 16 passes through the mechanical seal 14 and the concentration tank 10. A stirring blade 17 is fixedly installed on the stirring shaft 16. The stirring blade 17 is located inside the concentration tank 10, so that stirring is performed by rotating the stirring blade 17.
[0034] When the spherical concentrator of this utility model is in use, when the heating medium is a fluid, valve 20 is closed, and inlet pipe 18 and outlet pipe 19 are connected to the fluid delivery pipeline. As the heating medium enters the heating medium inlet chamber 111, it can heat the concentrator 10. The medium remaining in the heating medium inlet chamber 111 can be discharged out through condensate drain pipe 2.
[0035] When the heating medium is steam, connect the inlet pipe 18 and the outlet pipe 19 to the steam delivery pipeline, open the valve 20, and the steam enters the heating medium inlet chamber 111 and can perform normal heating operation. The generated condensate can enter the vertical pipe 21 through the condensate outlet pipe 2. As the condensate enters the expansion chamber 22, the float 26 can float up, driving the sealing ball 25 to move upward. The sealing ball 25 no longer blocks the conical cylinder 24, and the condensate can be discharged normally.
[0036] In addition, when the stirring motor 15 is connected to an external power source and put into operation, the stirring motor 15 drives the stirring shaft 16 and the stirring blades 17 to rotate, thus enabling the stirring operation.
[0037] After concentration, when there is residual condensate in the expansion chamber 22, push the push rod 27 upward to move the sealing ball 25 upward, at which point the accumulated water can be discharged.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
