Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to an electric constant temperature blast drying box. Background Art

[0002] Electric blast drying oven is also known as "drying oven". As the name implies, it uses electric heating to conduct blast cycle drying test. It is divided into blast drying and vacuum drying. Blast drying is to blow out hot air through a circulating fan to ensure the temperature balance in the box. Vacuum drying is to use a vacuum pump to extract the air in the box to make the atmospheric pressure in the box lower than normal pressure, so that the product can be tested in a very clean state. It is a commonly used instrument and equipment, mainly used to dry samples, and can also provide the temperature environment required for the experiment. Drying ovens are used in various industries such as chemical, pharmaceutical, casting, automobile, food, machinery, etc. They are generally divided into galvanized steel plate and stainless steel liner, pointer and digital display, natural convection and blast cycle, conventional oven and vacuum type.

[0003] At present, the existing utility model with publication number CN204494984U discloses an electric constant temperature blast drying oven, comprising a box body with a box door that can be opened and closed, the box body comprising an upper box wall, a lower box wall, a rear box wall and two side box walls, the box door in a closed state is parallel to the rear box wall and perpendicular to the side box walls, a plurality of pairs of protruding baffles are correspondingly arranged on the opposite surfaces of the two side box walls, the box wall of the box body and the box door are filled with heat preservation materials, and the side box walls are provided with a heat preservation material that can be sent into the box body. A blower for inlet air flow, a heating tube is arranged in the lower box wall, a thermometer is arranged in the box body, a display panel and a plurality of control buttons are arranged on the box body, the heating tube is connected to the corresponding control button through a controller signal, and the measurement result of the thermometer is output to the display panel. The drying box also includes a loading shelf that can be placed on the opposite baffle bar in the horizontal direction, and a heat insulation baffle that can be placed on the opposite baffle bar in a sealing manner in the horizontal direction. Exhaust holes are respectively opened on the upper box wall and the heat insulation baffle.

[0004] In the above scheme, the prior art adjusts the size of the effective drying space by adjusting the different positions of the insulation baffle. The user can adjust and reallocate the drying space according to actual needs, but the adjustment prevents the effective space size from being arbitrarily adjusted as needed, resulting in low utilization of the effective space. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an electric constant temperature blast drying box. By providing a guide adjustment component, the placement plate can be adjusted to a desired position as required, thereby solving the problem that the prior art cannot arbitrarily adjust the size of the effective space, thereby improving the utilization rate of the effective space of the drying liner.

[0006] The solution of the utility model to solve the technical problem is:

[0007] An electric constant temperature blast drying box comprises a drying box body, a box door is rotatably connected to the side wall of the drying box body, a drying device is installed in the drying box body, an upper end of the drying device is connected to an air outlet pipe, the end of the air outlet pipe is connected to the inner wall of the drying box body, a plurality of air outlet holes arranged in the same manner as the air outlet pipe are formed on the inner wall of the drying box body, a detachable drying liner is arranged in the drying box body, a plurality of groups of clamping components are arranged in the drying box body, a guide adjustment component is arranged in the drying liner, and a plurality of placement plates are arranged on the guide adjustment component.

[0008] When the material to be dried needs to be dried, the drying liner is placed in the drying box and fixed by a clamping assembly to prevent the drying liner from being separated from the drying box. At the same time, the position of the placement plate is adjusted by the guide adjustment assembly so that the placement plate can be adjusted to a desired position, thereby adjusting the size of the effective space as required, thereby improving the utilization rate of the effective space. The material to be dried is then placed on the placement plate, the box door is closed, and the drying device is started, thereby drying the material to be dried. At the same time, the drying liner is detachable, so when the material falls onto the bottom wall of the drying liner, the drying liner can be disassembled and cleaned, thereby improving the practicality of the utility model.

[0009] By providing a guide adjustment component, the placement plate can be adjusted to a desired position as required, solving the problem that the size of the effective space cannot be arbitrarily adjusted in the prior art, thereby improving the utilization rate of the effective space of the drying liner.

[0010] The utility model is further configured as follows: a plurality of air inlet holes are formed on the side wall and the top wall of the drying liner, a plurality of clamping plates are symmetrically fixed on the inner wall of the drying box, and a clamping groove cooperating with the clamping plate is formed on the side wall of the drying liner.

[0011] Through the above technical solution, when the drying liner needs to be installed in the drying box, the clamping groove is inserted into the clamping plate, and the air inlet hole is clamped on the clamping assembly, so as to fix the drying liner. At the same time, since the bottom wall of the drying liner is not provided with an air inlet hole, when the material falls on the bottom wall, the material is prevented from falling into the drying box through the air inlet hole.

[0012] The utility model is further configured as follows: the guide adjustment component includes a plurality of slide rails symmetrically fixed on the inner wall of the drying liner, a plurality of sliders are symmetrically fixed on the side wall of the placement plate, the sliders are slidably connected to the slide rails, a screw is threaded on the slider near the open end of the drying liner, and the screw passes through the protruding end of the slider and rests on the slide rail.

[0013] Through the above technical solution, when it is necessary to adjust the desired position of the placement plate, turn the screw to disengage the end of the screw from the slide rail, thereby driving the placement plate to move to the desired position, and then place the end of the screw against the slide rail to fix the placement plate in the desired position.

[0014] The utility model is further configured as follows: the clamping assembly includes a cylinder fixed on the inner wall of the drying box, a plurality of clamping strips are fixed to the end of the cylinder, a same connecting block is fixed to the ends of the plurality of clamping strips, and the end of the connecting block is rounded.

[0015] Through the above technical solution, when the drying liner needs to be clamped and fixed, the drying liner is inserted into the clamping plate, and the drying liner is pressed against the connecting block, and the drying liner is pushed inward. After the connecting block passes through the air inlet hole, the clamping strip is subjected to force and deformed, so that the drying liner is pressed against the cylinder after passing through the clamping strip, and the clamping strip is not subjected to force and returns to its original shape, so that the drying liner is clamped between the cylinder and the clamping strip, thereby clamping and fixing the drying liner. At the same time, the end of the connecting block is rounded, so as to facilitate the connection block to pass through the air inlet hole.

[0016] The utility model is further configured as follows: a water collecting box is placed on the bottom wall of the drying liner, and a handle is fixed on the side wall of the water collecting box.

[0017] Through the above technical solution, since the density of cold air inside the drying box is greater than that of hot air, when drying just starts, the cold air moves downward, forming water droplets on the surface of the water collecting box and are collected by the water collecting box, thereby preventing the water droplets from rusting the drying liner and increasing the drying effect of the drying liner.

[0018] The utility model is further configured such that: the transverse length of the clamping plate is greater than the transverse length of the clamping groove.

[0019] Through the above technical solution, the drying liner does not contact the inner wall of the drying box when it is inserted into the clamping plate, so that a cavity is formed between the drying liner and the drying box, so that the hot air generated by the drying device can easily enter the drying liner, thereby further improving the drying effect of the drying liner.

[0020] The utility model is further configured as follows: an observation window is fixed on the box door.

[0021] By adopting the above technical solution, when the material is being dried, it is convenient to observe the material through the observation window.

[0022] The utility model is further configured such that: the distance between the end of the slide rail and the upper surface of the clamping groove is equal to the thickness of the placement plate.

[0023] Through the above technical solution, the placement plate can be placed between the slide rail and the clamping groove, and the placement plate slidably connected to the slide rail can be taken out and cleaned, thereby further improving the practicality of the utility model.

[0024] The beneficial effects of the utility model are:

[0025] Compared with the prior art, by providing a guide adjustment component, the placement plate can be adjusted to the required position as needed, solving the problem that the prior art cannot arbitrarily adjust the size of the effective space, thereby improving the utilization rate of the effective space of the drying liner.

[0026] The water collecting box is provided to prevent water droplets from causing rust to the drying liner.

[0027] By providing an observation window, it is convenient to observe the material through the observation window. BRIEF DESCRIPTION OF THE DRAWINGS

The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] The following references Figures 1 to 5The utility model is described.

[0036] An electric constant temperature blast drying oven comprises a drying box body 1, a box door 2 is rotatably connected to the side wall of the drying box body 1, a drying device 3 is installed in the drying box body 1, an upper end of the drying device 3 is connected to an air outlet pipe 4, an end of the air outlet pipe 4 is connected to the inner wall of the drying box body 1, a plurality of air outlet holes 101 arranged in the same manner as the air outlet pipe 4 are formed on the inner wall of the drying box body 1, a detachable drying liner 5 is arranged in the drying box body 1, a plurality of groups of snap-on components are arranged in the drying box body 1, a guide adjustment component is arranged in the drying liner 5, and a plurality of placement plates 6 are arranged on the guide adjustment component.

[0037] When the material to be dried needs to be dried, the drying liner 5 is placed in the drying box 1 and fixed by a snap-fit ​​assembly to prevent the drying liner 5 from being separated from the drying box 1. At the same time, the position of the placement plate 6 is adjusted by the guide adjustment assembly so that the placement plate 6 can be adjusted to a desired position, thereby adjusting the size of the effective space as required, thereby improving the utilization rate of the effective space. The material to be dried is then placed on the placement plate 6, the box door 2 is closed, and the drying device 3 is started, thereby drying the material to be dried. At the same time, the drying liner 5 is detachable, so when the material falls onto the bottom wall of the drying liner 5, the drying liner 5 can be disassembled and cleaned, thereby improving the practicality of the utility model.

[0038] By providing a guide adjustment component, the placement plate 6 can be adjusted to a desired position as required, solving the problem that the size of the effective space cannot be arbitrarily adjusted in the prior art, thereby improving the utilization rate of the effective space of the drying liner 5.

[0039] A plurality of air inlet holes 501 are formed on the side wall and the top wall of the drying liner 5 , a plurality of clamping plates 7 are symmetrically fixed on the inner wall of the drying box body 1 , and a clamping groove 502 cooperating with the clamping plate 7 is formed on the side wall of the drying liner 5 .

[0040] When the drying liner 5 needs to be installed in the drying box 1, the clamping groove 502 is inserted into the clamping plate 7, and the air inlet hole 501 is clamped on the clamping assembly, so as to fix the drying liner 5. At the same time, since the bottom wall of the drying liner 5 is not provided with the air inlet hole 501, when the material falls on the bottom wall, the material is prevented from falling into the drying box 1 through the air inlet hole 501.

[0041] The guide adjustment assembly includes a plurality of slide rails 8 symmetrically fixed on the inner wall of the drying liner 5, and a plurality of sliders 9 symmetrically fixed on the side wall of the placement plate 6. The sliders 9 are slidably connected to the slide rails 8.

[0045] A water collecting box 14 is placed on the bottom wall of the drying liner 5 , and a handle 15 is fixed on the side wall of the water collecting box 14 .

[0046] Since the density of cold air inside the drying box 1 is greater than that of hot air, when drying begins, the cold air moves downward, forming water droplets on the surface of the water collecting box 14, and is collected by the water collecting box 14, thereby preventing the water droplets from rusting the drying liner 5 and increasing the drying effect of the drying liner 5.

[0047] The transverse length of the clamping plate 7 is greater than the transverse length of the clamping slot 502 .

[0048] When the drying liner 5 is inserted into the clamping plate 7, it does not contact the inner wall of the drying box 1, so that a cavity is formed between the drying liner 5 and the drying box 1, so that the hot air generated by the drying device 3 can easily enter the drying liner 5, thereby further improving the drying effect of the drying liner 5.

[0049] An observation window 16 is fixed on the box door 2.

[0050] When the material is being dried, it is convenient to observe the material through the observation window 16 .

[0051] The distance between the end of the slide rail 8 and the upper surface of the clamping groove 502 is equal to the thickness of the placement plate 6 .

[0052] Therefore, the placement plate 6 can be placed between the slide rail 8 and the clamping groove 502, and the placement plate 6 slidably connected to the slide rail 8 can be taken out and cleaned, thereby further improving the practicality of the utility model.

[0053] Working principle:

[0054] When it is necessary to dry the material to be dried, the clamping groove 502 is inserted into the clamping plate 7, and the drying liner 5 is pressed against the connecting block 13, and the drying liner 5 is pushed inward. After the connecting block 13 passes through the air inlet hole 501, the clamping strip 12 is deformed by force, so that the drying liner 5 is pressed against the cylinder 11 after passing through the clamping strip 12, and the clamping strip 12 is not forced to restore its original shape, so that the drying liner 5 is clamped between the cylinder 11 and the clamping strip 12, so that the drying liner 5 is clamped and fixed, and the screw 10 is rotated at the same time to make the end of the screw 10 disengage from the slide rail 8, so that the placement plate 6 can be driven to move to the desired position, and then the end of the screw 10 is pressed against the slide rail 8, so that the placement plate 6 is fixed in the desired position, so that the size of the effective space can be adjusted as needed, thereby improving the utilization rate of the effective space, and then the material to be dried is placed on the placement plate 6, the box door 2 is closed, and the drying device 3 is started, so that the material to be dried can be dried.
