Abstract

The utility model relates to a reaction-filtering-drying multi-functional machine. The structure of the utility model is characterized in that a shell body which can rotate round a shaft can be positioned at the positions of different operating conditions to orderly complete the operating conditions of reaction crystallisation, filtration washing, drying, discharging, etc. In reaction crystallization, cooling water is led into a jacket which is installed outside a shell body to remove heat; In drying, steam is led into the jacket for heating. A stirring shaft is composed of a solid shaft and a hollow shaft which are connected with a symmetrical double bond; the solid shaft and the hollow shaft can relatively slip and rotate synchronously. The solid shaft is provided with a lifting device; the solid shaft and the hollow shaft are respectively provided with stirring paddles. Due to the fact that various operating conditions are completed in one sealed machine body, the utility model creates advantages for realizing sterile operation and improving the quality of products.

Description

Reaction-filtering-drying multi-fnctional machine

The utility model belongs to chemical industry equipment, relates to reaction, filtration and the drying equipment used when producing chemical industry or medical product.

Usually when producing chemical industry or medical product, need in several autonomous devices, react successively, the unit operations of projects such as crystallization, filtration and drying, need between the equipment to connect with pipeline, this had both existed equipment complexity and transportation problem, also exist the product loss many, shortcomings such as easy polluted product.

The purpose of this utility model is to adopt a specific installation to finish multiple functions such as reaction, crystallization, filtration and drying, overcomes the transportation problem that plurality of devices in the past causes, and reduces the loss and pollute.

Can be specified by shown in the accompanying drawing in order to finish the technical scheme that above-mentioned task takes.

The drawing explanation:

Fig. 1 is the utility model structural representation;

Fig. 2 be used to react, the equipment state schematic diagram of crystallization operating mode;

Fig. 3 is the equipment state schematic diagram that is used to filter, wash operating mode;

Fig. 4 is the equipment state schematic diagram that is used for dry operating mode;

Fig. 5 is the equipment state schematic diagram that is used for the discharging operating mode.

The utility model structure scheme mainly is made up of housing, chuck, rotating shaft, stirring oar, filter and transmission device. Its characteristics are as shown in Figure 1: this engine housing 6 is installed on the support 9 by axle 8, and housing rotates around axle 8 and can be positioned on different Working pasitions; When rotating, housing in order to reduce the connecting pipe motion, connects plate 21 at axle 8 one ends dress flexible pipe, the other end dress drive disk assembly of axle; In the housing outside chuck 10 is housed, the in-built spiral deflector 11 of chuck is equipped with cooling water import 7, cooling water outlet 12 and steam condensed water outlet 20 on the chuck, and the cooling water outlet can be made the heating steam entrance again; When reactive crystallization, carry cooling water to reduce phlegm and internal heat in the chuck, and in drying Be input into heating steam during crystal in the chuck; Stir axle along the axis installation in the housing, stirring axle is made up of solid shafting 13 and hollow shaft 23, the lower end dress of solid shafting oar formula stirs oar 14, the other end passes the interior hole of hollow shaft and is connected with axle lifting device 2, be connected by the symmetric double key between hollow shaft and the solid shafting, two axles not only can relative to slide but also can rotating synchronously, be equipped with the anchor formula in hollow shaft and stir oar 22; Axle promotes device 2 and comprises that hydraulic means 1 and bidirectional propulsion bearing form, and bearing block is connected with the hydraulic means piston rod, and solid shafting 13 upper ends are fastened in the bearing and put; At bearing 18 worm gear worm screw 3 is housed, hollow shaft 23 upper ends and worm gear axis hole are fixedly attached, and worm gear worm-drive hollow shaft and then drive solid shafting rotate synchronously; In hollow shaft and shell end junction mechanical seal 4 is installed, can adopts 537 type single mechanical end face seals, easy accessibility, good seal performance, long service life is established flushing hole on the seal cover, but both coolant seal end faces can prevent gathering of crystallization thing again; Also can do filtrate outlet at vacuum mouth 17() be positioned at filter 16 under, powder enters the vacuum mouth when utilizing filter medium can stop vacuum dry, both can reduce the product loss, makes again the vacuum system not contaminated. Filter adopts the common filtration at card pad filter screen.

The residing different conditions of the corresponding various operating modes of the utility model:

1. the state during reactive crystallization

As shown in Figure 2, roll-shell 6 makes its axis vertical with horizontal plane, and filter 16 feeds cooling water up in the chuck 10, and paddle slowly rotates in order to crystallization;

2. the state during filtration washing

As shown in Figure 3, by the reactive crystallization state housing is turned over 180 °, filter down, be input into pressed gas through pressurization mouth 24, carry out pressure filtration, lifting paddle 14 also slowly rotates the crystalline solid leveling is promptly shut down, filtration finishes when needing washing, spray into cleaning solution by nozzle, stir filter cake simultaneously, filtrate and cleaning solution are emitted through filtrate (liquid 17;

3. the state when dry

As shown in Figure 4, by the filtration washing state housing is turned over 135 °, drying tilts, inclination can increase heat-transfer area, this moment, 12 feeding heating steams were heated hothouse from the steam inlet, and the hothouse temperature is monitored by thermocouple, the dry gas that produces, extract out by vavuum pump by vacuum port 17, uniform drying should be stirred simultaneously for strengthening heat-transfer effect;

4. the state during discharging

Behind dry the end, equipment is changeed 70 ° again, as shown in Figure 5, make discharge port vertically downward, stir discharging.

Advantage of the present utility model:

When production chemical product or medicine, use the utility model and four kinds of operating modes such as reactive crystallization, filtration washing, heat drying and discharging can be finished in a machine, cause mechanism's compactness, floor space is little, and manufacturing cost reduces, and is easy for operation; Owing in the body of a sealing, finish each operating mode, avoided the conveying connecting link between each unit, reduce effectively and pollute and reduce material loss, for sterile working with improve the quality of products and create favorable conditions.
