Description

Technical Field

[0001] The utility model relates to a container corner casting auxiliary device, in particular to a steel shot box used for container corner casting. Background Art

[0002] Sand casting refers to a casting method that produces castings in sand molds. Since the molding materials used in sand casting are cheap and easy to obtain, and the molds are simple to manufacture, it is adaptable to single-piece production, batch production, and mass production of castings. Steel, iron, and most non-ferrous alloy castings can be obtained by sand casting. In the production and casting of containers, sand casting is also used. The sand mold is prefabricated into the style of corner pieces, and then the molten steel is poured into the sand mold to cool. After cooling, the formed container corner pieces can be obtained.

[0003] In the prior art, before pouring molten steel, the mold needs to be buried in a landfill box, and the sand mold is cooled by the steel shots in the landfill box, thereby conducting the heat during the molding of the corner piece to the inside of all the steel shots. The steel shots need to be recovered after heating and wait for secondary utilization. All the recovered steel shots will be stored in a steel shot warehouse, where they will be cooled before being used. When the steel shots are unloaded, if the temperature of the steel shots is too high, it will affect the production efficiency and quality both when burying the shell and when pouring.

[0009] As a further improvement, the forward and reverse flow driving structure includes a sealing and pushing member arranged on the inner wall of the steel shot box, the sealing and pushing member is located at the upper edge of the inner bucket frame, and the sealing and pushing member is used to open and close the upper edge of the inner circulation channel.

[0010] As a further improvement, the forward and reverse flow driving structure also includes a third screw feeder arranged in the inner circulation channel. When the sealing and pushing member is opened, the third screw feeder rotates forward to transport the steel shots in the inner circulation channel to the feed pipe.

The water-cooling circulation structure includes a circulation pipeline fixedly connected to the first partition plate and the second partition plate, and the liquid inlet end and the liquid outlet section of the circulation pipeline are both connected to a compressor.

[0014] The beneficial effects of the utility model are:

[0015] In the existing container corner molding equipment, all of them are formed by sand casting, and sand casting adopts the cooling method of steel shots. In the existing steel shot storage structure, the steel shots are often stored and cooled only in a large box, but this makes it easy to use the newly input steel shots, and the temperature of the newly input steel shots is extremely high. If such steel shots are used directly in the landfill box, it will affect the structure of the mold and further affect the molding quality of the corner pieces. Therefore, the utility model, through the segmented storage and feeding mechanism, first divides the entire steel shot box into a plurality of chambers through the first partition plate and the second partition plate, so that the steel shots to be used and the steel shots to be stored can be divided into different areas to avoid heat superposition, and corresponding screw feeders are used in different chambers for feeding, thereby forming a continuous and stable storage and supply route, so that the steel shots can be better cooled even if they are stored in the steel shot box, and the heat can meet the requirements of unloading after being stored for a period of time.

[0016] During the feeding stage of steel shots, if the temperature of the steel shots discharged into the landfill box does not meet the requirements, it will directly affect the production of the products. For example, the surface of the corner pieces may have burrs or depressions, and it is extremely easy to cause the same condition in the entire batch, which often causes a large number of products to appear after being discovered. Therefore, the utility model is provided with a temperature screening mechanism on the basis of the segmented storage and feeding mechanism. When the steel shots are discharged through the feeding pipe, they need to pass through the temperature detector. In the normal stage, that is, when the temperature of the steel shots meets the detection requirements of the temperature detector, the forward and reverse flow driving structure is in a forward rotation mode, that is, the steel shots falling into the inner circulation channel will be transported downward to the position of the feeding pipe. At this time, since the solenoid valve is normally opened, the material can be discharged normally. When the temperature of the steel shots does not meet the detection requirements of the temperature detector, the solenoid valve is automatically closed, and the forward and reverse flow driving structure is reversed to transport the steel shots retained at the feeding pipe to the outside, and the equipment is shut down for cooling, so that the temperature of the steel shots outputting the equipment always meets the requirements.

[0026] Reference Figure 1 to Figure 4As shown, a steel shot box for casting container corner parts comprises a vibration sorting structure 10 connected to a landfill box conveyor line, the steel shot discharge port of the vibration sorting structure 10 is connected to a first screw feeder 20, the first screw feeder 20 is in communication with a steel shot box 30, the casting molding equipment further comprises: a segmented storage and feeding mechanism, comprising a first partition plate 31 arranged inside the steel shot box 30, the first partition plate 31 divides the steel shot box 30 into a left chamber and a right chamber, the bottom of the first partition plate 31 is fixedly connected to the bottom of the steel shot box 30, and the top of the first partition plate 31 is spaced apart from the top of the steel shot box 30, a second screw feeder 32 is arranged on the left side of the first partition plate 31, a second partition plate 33 is arranged at the midline position of the left chamber, the second partition plate 33 is fixedly connected to the top of the steel shot box 30, and the second partition plate 33 is spaced apart from the bottom of the steel shot box 30, the first screw feeder 20 feeds the steel shots sorted by the vibration sorting structure 10 to the right chamber, and the first partition plate 31 is fixedly connected to the top of the steel shot box 30, and the second partition plate 33 is spaced apart from the bottom of the steel shot box 30, and ... The steel shot box 30 is delivered to the space on the left side of the second partition plate 33. A plurality of delivery pipes 34 are opened on the right side of the bottom of the steel shot box 30. When the delivery pipe 34 is unloaded, the second screw feeder 32 delivers the steel shot in the left chamber to the right chamber, so that the delivery pipe 34 always outputs the steel shot with the lowest temperature in the steel shot box 30; a temperature screening mechanism, the delivery pipe 34 is a funnel-shaped structure, and the temperature screening mechanism includes an inner bucket frame 41 arranged in the delivery pipe 34, and a temperature detector 42 is arranged on the inner side of the inner bucket frame 41 An inner circulation channel 43 is formed between the inner bucket frame 41 and the feed pipe 34, and a positive and negative flow driving structure 44 is arranged in the inner circulation channel 43. A solenoid valve is arranged at the opening of the feed pipe 34. When the temperature detector 42 detects that the temperature meets the requirements, the solenoid valve opens, and the feed pipe 34 discharges materials normally. When the temperature detector 42 detects that the temperature is higher than the set value, the solenoid valve closes, and the positive and negative flow driving structure 44 transports the steel shots that do not meet the requirements to the left chamber of the steel shot box 30.

[0027] In this embodiment, the vibration sorting structure 10 is a vibration screening machine, wherein the vibration screening machine is a prior art, and thus will not be described in detail in this case.

[0028] In this case, there are multiple screw feeders, all of which adopt existing feeders, which can convey light steel shots without damaging the spiral blades. In this embodiment, the particle size of the steel shots is 2.5 to 3.5 cm.

[0029] In the existing container corner molding equipment, all of them are formed by sand casting, and sand casting adopts the cooling method of steel shots. In the existing steel shot storage structure, the steel shots are often stored and cooled in a large box, but it is easy to use the newly input steel shots. The temperature of the newly input steel shots is extremely high. If such steel shots are used directly in the landfill box, it will affect the structure of the mold and further affect the molding quality of the corner pieces. Therefore, the utility model uses a segmented storage and feeding mechanism to first divide the entire steel shot box 30 into a plurality of chambers through a first partition plate 31 and a second partition plate 33, so that the steel shots to be used and the steel shots to be stored can be divided into different areas to avoid heat superposition, and corresponding screw feeders are used in different chambers to feed, thereby forming a continuous and stable storage and supply route, so that even if the steel shots are stored in the steel shot box 30, they can be better cooled, and the heat can meet the requirements of unloading after being stored for a period of time.

[0030] During the unloading stage of the steel shots, if the temperature of the steel shots discharged into the landfill box does not meet the requirements, it will directly affect the production of the products. For example, the surface of the corner pieces may have burrs or depressions, and it is extremely easy to cause the same condition in the entire batch, which often causes a large number of products to appear after being discovered. Therefore, the utility model is provided with a temperature screening mechanism on the basis of the segmented storage and loading mechanism. When the steel shots are unloaded through the delivery pipe 34, they need to pass through the temperature detector 42. In the normal stage, that is, when the temperature of the steel shots meets the detection requirements of the temperature detector 42, the forward and reverse flow driving structure 44 is in a forward rotation mode, that is, the steel shots falling into the inner circulation channel 43 will be transported downward to the position of the delivery pipe 34. At this time, since the solenoid valve is normally opened, the unloading can be normal. When the temperature of the steel shots does not meet the detection requirements of the temperature detector 42, the solenoid valve is automatically closed, and the forward and reverse flow driving structure 44 is reversed, and the steel shots retained at the delivery pipe 34 are transported to the outside, and the equipment is shut down for cooling, so that the temperature of the steel shots output from the equipment always meets the requirements.

[0031] There is actually a certain gap between the inner bucket frame 41 and the feed pipe 34, namely the inner circulation channel 43. In order to make full use of this gap and increase the storage capacity of steel shots, this gap also accommodates steel shots in the normal stage, and it can transport the steel shots to the position of the feed pipe 34 as the third spiral feeder 442 rotates forward, thereby avoiding the accumulation of steel shots. In the stage where the temperature is not suitable, the forward and reverse flow driving structure 44 of this embodiment includes a sealing push member 441 arranged on the inner wall of the steel shot box 30, and the sealing push member 441 is located at the upper edge of the inner bucket frame 41. The sealing push member 441 is used to open and close the upper edge of the inner circulation channel 43, and the gap between the inner bucket frame 41 and the feed pipe 34 can be sealed by the sealing push member 441 to prevent the steel shots from falling from this position and to avoid affecting the reversed third spiral feeder 442. Among them, the sealing push member 441 is a hydraulic push rod in the prior art, and the hydraulic push rod is connected to a closing plate, and the hydraulic push rod has a strong pressure bearing capacity.

[0032] The forward and reverse flow driving structure 44 in this embodiment also includes a third screw feeder 442 arranged in the inner circulation channel 43. When the sealing and pushing member 441 is opened, the third screw feeder 442 rotates forward to transport the steel shots in the inner circulation channel 43 to the feed pipe 34. When the sealing and pushing member 441 is closed, the third screw feeder 442 reverses to transport the steel shots in the feed pipe 34 to the left chamber of the steel shot box 30. By arranging the third screw feeder 442 in the gap between the inner bucket frame 41 and the feed pipe 34, the motor driving the third screw feeder 442 can rotate forward and reverse. The logic of the forward and reverse switching of the motor is carried out according to the detection data of the temperature detector 42, so that it can rotate in different directions at different stages to achieve different purposes.

[0033] Among them, the temperature detector 42 is a temperature sensor, and the temperature sensor is electrically connected to the motor driving the third screw feeder 442. It is a prior art to control the forward and reverse directions of the click by using a temperature sensor, so it will not be repeated here.

[0034] Since the temperature of the steel shots after being reversed by the third screw feeder 442 does not meet the requirements, they need to return to the front section for further cooling. Therefore, the unloading end of the third screw feeder 442 of this embodiment is provided with a plurality of feeding belts 443, and the feeding belts 443 extend to the first screw feeder 20. By providing the feeding belts 443 on the basis of the third screw feeder 442, the steel shots that do not meet the temperature requirements can be transported back to the first screw feeder 20 through the provision of several sections of the feeding belts 443, and then enter the delivery pipe 34 after being re-cooled. The feeding belt 443 is provided with more than one section, and it needs to be reversed and lifted, so as to accurately transport the steel shots to the feed port of the first screw feeder 20. In the figure, only one section of the feeding belt 443 can be seen. In fact, multiple sections of the feeding belts 443 need to be provided to transport the steel shots to the first screw feeder 20.

[0035] The steel shots transported back to the first screw feeder 20 do not enter the steel shot box 30 through the uppermost inlet in the same way due to their different temperatures. In this regard, the steel shot box 30 of this embodiment is provided with a plurality of feeding troughs 301 on the side close to the first screw feeder 20, and the first screw feeder 20 is provided with a plurality of discharging troughs 21, and the discharging troughs 21 are provided with a discharging switch. The temperature detector 42 detects the temperature range corresponding to the steel shots to be recycled and turns on the corresponding discharging switch. A plurality of feeding troughs 301 are provided on the steel shot box 30, and the discharging at different positions is performed through the discharging troughs 21 on the first screw feeder 20, so that the steel shots can be output to the corresponding areas, thereby avoiding the mixing of steel shots with large temperature differences. The discharging switch can provide a certain feeding pressure, so that the steel shots can smoothly enter the corresponding areas.

[0036] During the storage of the steel shot in the steel shot box 30, it not only relies on natural cooling, but also relies on the auxiliary cooling of the cooling equipment in the steel shot box 30. In this embodiment, two cooling means are set in the steel shot box 30, namely, air cooling and liquid cooling. First, the outside of the steel shot box 30 is locked with an air cooling structure, and the air cooling structure includes a suction pipe 51 that runs through the steel shot box 30. The suction pipe 51 is connected to a suction pump 52 fixedly connected to the outside of the steel shot box 30. The heat emitted by the steel shot is sucked out of the outside of the steel shot box 30 in time through the suction pump 52 through the arranged suction pipe 51. Secondly, since the steel shot cannot directly contact water, otherwise it is easy to rust, this embodiment The first partition plate 31 and the second partition plate 33 of the embodiment are both hollow, and the steel shot box 30 is respectively provided with a water-cooling circulation structure 60 that penetrates the first partition plate 31 and the second partition plate 33. The water-cooling circulation structure 60 includes a circulation pipeline 61 fixedly connected to the first partition plate 31 and the second partition plate 33. The liquid inlet end and the liquid outlet section of the circulation pipeline 61 are both connected to a compressor 62. By providing the water-cooling circulation structure 60 on the first partition plate 31 and the second partition plate 33, the steel shots can be cooled by water through indirect contact with the condensate. Thus, the two cooling methods are combined to allow the steel shots to be cooled quickly.

[0037] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
