The totally-enclosed liquid heating dewaxing device of environmental protection
Technical field
The invention belongs to technical field of medical instruments, more particularly to a kind of totally-enclosed liquid heating dewaxing device of environmental protection.
Background technology
It is well known that must be to biological tissue embedding unit or template casting, for biology during biological tissue's making section
Organization embedding unit, embedding mould, dehydration column, dewatering holder or template casting concrete structure are as disclosed in ZL201520240029.7
, also in the market also has many similar products certainly, and their purpose is fixed biological tissue sample, but microsection manufacture is complete
Cheng Hou, described biological tissue embedding unit, embedding mould or template all can more or less hang with residual paraffin, the cleaning of these paraffin
Get up very difficult.Traditional electric oven thermal evaporation is but this mode by high-temperature gasification by the extension wax on pending article
Power consumption is big simultaneously for the meeting substantial amounts of flue gas of bad student, and this flue gas directly endangers the health of staff, and the mode generally solved is
Evacuated or opened a window natural diffuseness by blower fan, and this process in order to avoid endangering the health of staff, typically can by staff
Station is left, is just returned to after flue gas is cleared in operating room, unserviced heat treatment process has potential safety hazard.
The content of the invention
In order to solve the above technical problems, the present invention proposes a kind of totally-enclosed liquid heating dewaxing device of environmental protection, its design
Rationally, the purpose hung wax by heating liquid fusing and reach paraffin removal.
The technical proposal of the invention is realized in this way:
A kind of totally-enclosed liquid heating dewaxing device of environmental protection, it includes casing, and motor drive is provided with the casing
Dynamic and heatable roller, biological tissue embedding unit, embedding mould, dehydration column, dewatering holder or template are evenly equipped with roller
Fixed mount, the roller be communicated with upwards liquid feed valve, pass downwardly through discharging tube, liquid pump connects with leakage fluid dram;On the casing
Control panel is additionally provided with, the control panel is connected by circuit with motor, water intaking valve and liquid pump.
As further technical scheme, the boiling point of the liquid is more than paraffin melting point, and liquid heating-up temperature is more than paraffin
Melting point temperature.
As further technical scheme, the liquid is water.
As further technical scheme, the discharging tube is divided into upper strata de-waxing pipe and lower floor's draining with electromagnetic valve
Pipe.
As further technical scheme, the upper strata de-waxing pipe and lower floor's drainpipe access liquid pump in parallel, the liquid
Pump connects leakage fluid dram by being incubated comb.
As further technical scheme, the roller is vertical rotary cylinder or horizontal drum.
Beneficial effects of the present invention are:Liquid heating paraffin removal, nonpoisonous and tasteless, smokeless production are utilized in totally enclosed environment
It is raw, the health of staff will not be endangered;In addition, the present apparatus can automatically, efficiently, thoroughly, energy-conserving and environment-protective, the completion paraffin removal of safety
Operation, save very big workload for staff while also improve the checkability of hospital.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Example 1:
As shown in Figures 1 to 3, dewaxing device is heated for a kind of totally-enclosed liquid of environmental protection of the present invention, including:
Casing 1, motor 6 is provided with the casing 1 and is driven and heatable horizontal drum 5, in horizontal drum 5
The fixed mount 11 of biological tissue embedding template 10 is evenly equipped with, the horizontal drum 5 is communicated with water intaking valve 3, the row of passing downwardly through upwards
Liquid pipe, liquid pump 7 connect with leakage fluid dram;Control panel 2 is additionally provided with the casing 1, the control panel 2 passes through circuit and electricity
Machine 6, water intaking valve 3 and liquid pump 7 connect.
Because water is immiscible with paraffin, described discharging tube carries the upper strata de-waxing pipe 12 and band of upper strata electromagnetic valve 13
Lower floor's drainpipe 16 of lower floor's electromagnetic valve 17.
The access liquid pump 7 in parallel of upper strata de-waxing pipe 12 and lower floor's drainpipe 16, the liquid pump 7 is by being incubated comb 14
Connect leakage fluid dram.
Also include observation window 8, display screen 9 and resistive heater 15 in other figure.
During work, the biological tissue embedding template 10 for treating paraffin removal is fixed in horizontal drum 5 by fixed mount 11, closed
Observation window 9, opens water intaking valve 3 and adds water into horizontal drum 5, controls the water level in roller by level control switch for water 4, reaches pre-
Water intaking valve 3 is closed after determining water level, sets heating-up temperature and the flip-flop transition of horizontal drum 5 by control panel 2, motor 6 drives sleeping
Water is gradually heated by the sonochemical activity while formula roller 5 is overturn, after water temperature reaches paraffin melting point, the extension wax in biological tissue embedding template 10
Come off, swim in water surface upper strata, after reaching preset operating time, upper strata electromagnetic valve 13 is opened, lower floor's electromagnetic valve 17 is closed,
Liquid pump 7 extracts the paraffin for swimming in water surface upper strata out horizontal drum 5 by upper strata de-waxing pipe 12, in order to prevent paraffin in discharge opeing
During solidify, resistive heater 15 keeps the temperature in insulation comb 14, after paraffin emptying, upper strata electromagnetic valve 13 closes,
Lower floor's electromagnetic valve 17 is opened greatly, and remaining water is discharged by lower floor's drainpipe 16 in horizontal drum 5.
In order to prevent the paraffin of discharge from causing secondary pollution to environment, insulation comb 14 is further connected with returnable.
Example 2:
The difference of example 2 and example 1 is:Roller is changed to vertical rotary cylinder by horizontal drum, treats the product of paraffin removal by biology
Organization embedding template is changed to multifunction organization embedding mould 18, first will be multi-functional due to the small volume of multifunction organization embedding mould 18
Organization embedding mould 18 is fixed on fixed mount 11 after packing, as shown in Figure 4.Other structures, operation principle are identical with example 1, therefore
Omit.
These are only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
