Description
Technical field
The present invention relates to a kind for the treatment of apparatus of hot investment casting Lasaxing Oilfield system, be specifically related to improve the quality of process wax liquid and the hot investment casting Lasaxing Oilfield system wax liquid automatic sand removal de-watering apparatus of efficiency.
Background technology
At present, domestic production efficiency for improving precision investment casting and the physical labor intensity alleviating workman generally adopts mechanical production line in dewaxing and the operation such as Lasaxing Oilfield, shell processed, and dewaxing technique generally adopts steam type to dewax.This kind of dewaxing mode be the wax-pattern making shell is placed on dewaxing kettle top and allow its sprue gate down, be filled with HCS and make wax melt flow drop on the bottom of dewaxing kettle.Gas shock when expanding after the shell heating mutually collide with because shell exists when loading and take out dewaxing kettle, be deposited in dewaxing kettle or be filled with steam makes shell mutually wear and tear, the bonding factor such as insecure of shell material processed makes shell material processed (sand, powder) come off from shell and be mixed in wax liquid.Paraffin can be mixed into a large amount of sand powder after Reusability, has a strong impact on the processing performance of paraffin, thus affects the surface quality of wax-pattern, reduces the intensity of wax-pattern, increases the distortion probability of wax-pattern, and then affects the quality of foundry goods.In traditional wax liquid treating system, be generally provided with multiple tracks wax liquid leave standstill device, which increase the use number of units of equipment and energy-output ratio and expand the floor space of equipment, more importantly because stationary equipment structure exists irrationality to making wax liquid treatment effect undesirable, and operate cumbersome in production process, plant maintenance difficulty.
Summary of the invention
The object of the present invention is to provide that a kind for the treatment of effeciency is high, the hot investment casting Lasaxing Oilfield system wax liquid automatic sand removal de-watering apparatus of economize energy, it has simple, rationally distributed, easy to use, the economical and practical feature of structure.
For achieving the above object, hot investment casting Lasaxing Oilfield system wax liquid automatic sand removal de-watering apparatus of the present invention, comprise staving, the outside seal weld of described staving is connected to housing, inside is provided with the wax storage tank body of opening, and the opening of wax storage tank body, lower than the upper surface of staving, fills conduction oil in the cavity formed and be provided with electric heating tube between staving and housing, the cavity top formed between staving and wax storage tank body is provided with ingress pipe, and bottom is provided with vomit pipe; The side of described staving is connected with hollow water level control pipe, and the side, bottom of hollow water level control pipe is provided with outlet, is provided with sewage draining valve in the middle of the bottom of hollow water level control pipe; Fill hot water in the cavity formed between described staving and wax storage tank body and thermocouple is installed.
The bottom surface of described wax storage tank body is set to inclined plane.
Described vomit pipe is provided with dispensing valve.
Adopt after technique scheme, owing to filling conduction oil in the cavity that formed at staving and housing and being provided with electric heating tube, by the temperature of electric heating tube change conduction oil, make it keep constant temperature, thus water temperature maintenance between staving and wax storage tank body is constant; By the control of thermocouple to hot water temperature, the setting of water temperature during to realize the process of wax liquid; Hollow water level control pipe controls the height of water level between staving and cylinder body automatically, be mainly manifested in: the water entered in staving with wax liquid is overflowed, guarantee that the water level between staving and wax storage tank body can not rise and enter in wax storage tank body, thus realize to wax liquid except water function; The side, bottom of hollow water level control pipe is provided with outlet, sewage draining valve is provided with in the middle of the bottom of hollow water level control pipe, assorted material (as impurity such as the sand powder) proportion be mixed in pending like this wax liquid is larger than water, it can be settled down to bottom staving downwards in water, regularly open sewage draining valve to discharge, make thus realize impurity functions such as the desanding powder of wax liquid.
Further, the bottom of described wax storage tank body is set to inclined plane, is beneficial to the precipitums such as sand powder and discharges to sewage draining exit place.
Further, described vomit pipe is provided with dispensing valve, and the wax liquid processed is stored in wax storage tank body, needs to open dispensing valve when using, and can collect the wax liquid that purity is high.
Accompanying drawing explanation
Fig. 1 is hot investment casting Lasaxing Oilfield system wax liquid automatic sand removal de-watering apparatus profile of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, hot investment casting Lasaxing Oilfield system wax liquid automatic sand removal de-watering apparatus of the present invention is described further;
As seen from Figure 1, hot investment casting Lasaxing Oilfield system wax liquid automatic sand removal de-watering apparatus of the present invention, comprise staving 1, the outside of described staving 1 is sealedly connected with housing 2, inside is provided with the wax storage tank body 3 of opening, and the opening of wax storage tank body 3, lower than the upper surface of staving 1, fills conduction oil 4 in the cavity formed and be provided with electric heating tube 5 between staving 1 and housing 2, the cavity top formed between staving 1 and wax storage tank body 3 is provided with ingress pipe 6, and bottom is provided with vomit pipe 7; The side of described staving 1 is connected with hollow water level control pipe 8, and the side, bottom of hollow water level control pipe 8 is provided with outlet 81, is provided with sewage draining valve 82 in the middle of the bottom of hollow water level control pipe 8; Fill hot water 9 in the cavity formed between described staving 1 and wax storage tank body 3 and thermocouple 10 is installed.
When using of the present invention, pending wax liquid inputs to hot water 9 from ingress pipe 6, because the proportion of wax liquid is less than water, thus wax liquid can move upward and float up to the water surface in hot water 9, along with the continuous floating of wax liquid, the wax liquid layer thickness being present in water surface constantly increases, and just flows into wax storage tank body 3 store insulation when wax liquid level rises to wax storage tank body 3 cylinder mouth position, and when needing to use, wax liquid flows out from vomit pipe 7.Wherein, pending wax liquid directly extracts out from dewaxing kettle, owing to using autoclave dewaxing, wherein enter in staving 1 containing large quantity of moisture with wax liquid, hollow water level control pipe 8 makes the water entered in staving 1 with wax liquid overflow, guarantee that in staving 1, water level can not rise and enter wax storage tank body 3 li, thus realize to wax liquid except water function; In addition, impurity (as shell material processed, the sand powder etc.) proportion be mixed in pending wax liquid is larger than water, can be settled down to the bottom surface of staving 1 in water downwards, regularly opens blowoff valve 82 and is discharged by impurity, thus realize the impurity removal function to wax liquid.
In the present embodiment, the bottom of described wax storage tank body 3 is set to inclined plane, is conducive to the impurity such as shell material processed, sand powder and discharges from sewage draining exit; Described vomit pipe 7 is provided with dispensing valve 71, and the wax liquid processed is stored in wax storage tank body 3, needs to open dispensing valve 71 when using, and can collect the wax liquid that purity is high.
The structure of hot investment casting Lasaxing Oilfield system wax liquid automatic sand removal de-watering apparatus of the present invention is not limited to above-mentioned concrete mode; as the installation site of electric heating tube 5; the position of vomit pipe 7, outlet 81 can change according to the apparatus arrangement situation of production scene, all belongs within scope.
