A kind of inclined feeding calcining tube furnace

Abstract

The utility model discloses an inclined feeding calcining tube furnace, comprising: a furnace body, a furnace frame arranged at the bottom of the furnace body; and the top of the furnace frame is inclined so as to make the furnace body inclined. The calcining furnace tilts the top of the furnace frame so that the furnace body follows the furnace frame to keep tilting. During operation, the furnace chamber is filled with materials. After the materials enter from the feeding port, the materials are stacked in sequence. Through the inclined state of the furnace body and the gravity of the materials themselves, the materials slowly slide through the furnace chamber in a free-falling manner for heat treatment. The sliding speed of the materials is controlled by controlling the rotation speed of the rotary mechanical valve of the discharge valve, so that the materials are fully in contact with the heat source. There is no need to use a boat to carry the materials, and the material loading in the furnace chamber is increased, so that a large number of materials can be continuously heat treated. The heating effect is more uniform, and the quality of the heat treatment of the materials is improved. The production efficiency and the heat treatment quality of the materials are improved without changing the structure of the original calcining tube furnace.

Description

Technical Field

[0001] The utility model relates to the technical field of calcining furnace metallurgy, in particular to an inclined feeding calcining tube furnace. Background Art

[0002] In the field of powder metallurgy, granular powdered materials need to be heat treated in a calcining furnace. Currently, three conveying methods are usually used for material heat treatment. The first is the push-boat type, in which the metal powdered materials need to be placed in a boat box, and the boats are queued and pushed forward; the second is the steel belt type, in which the metal powdered materials are spread flat on the steel belt and moved forward continuously; the third is the inclined rotating furnace tube type, in which the metal powdered materials are conveyed forward in a slightly inclined rotating furnace tube.

[0003] In the related art, since metal materials usually withstand temperatures below 1000°C, steel belt and inclined rotating furnace tube conveying methods are only used for heat treatment below 1000°C; and heat treatment of materials above 1000°C mainly adopts push-boat conveying, but the boat box occupies a large space, the material carrying capacity is limited, and the material unloading steps are cumbersome. The automated mechanism that needs to be coordinated with it has a complex structure, a high failure rate, and low production efficiency. In addition, the material is loaded in the boat and heated unevenly, and the heat treatment quality of the material cannot be guaranteed. Utility Model Content

[0004] The purpose of the utility model is to provide an inclined feeding calcining tube furnace to solve at least one aspect of the problems and defects raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An inclined feeding calcining tube furnace, comprising:

[0007] A furnace body, wherein a furnace frame is arranged at the bottom of the furnace body;

[0008] The furnace body comprises a furnace, and a muffle furnace tube is arranged in the furnace;

[0009] One end of the furnace is connected to a feeding port, and the other end is connected to a furnace tail cooling pipe;

[0010] One end of the furnace tail cooling pipe is connected to a material collecting barrel, and a discharge valve is provided between the furnace tail cooling pipe and the material collecting barrel;

[0011] The top of the furnace frame is tilted, so that the furnace body is tilted.

[0012] The inclined feeding calcining tube furnace according to this scheme has at least the following technical effects:

[0013] By tilting the top of the furnace frame so that the furnace body follows the furnace frame to keep tilting, the inclined feeding calcining tube furnace is in operation with the furnace chamber filled with materials, so that after the materials enter from the feeding port, the materials are stacked in sequence, and slowly pass through the furnace chamber for heat treatment in a free sliding manner through the tilted state of the furnace body and the gravity of the materials themselves, and the sliding speed of the materials is controlled by controlling the rotation speed of the rotary mechanical valve of the discharge valve, so that the materials are fully in contact with the heat source, and there is no need to use a boat to carry the materials, which saves space in the furnace chamber, increases the material loading in the furnace chamber, realizes continuous heat treatment of large quantities of materials, and has a more uniform heating effect, thereby improving the quality of heat treatment of materials, and improving the production efficiency and heat treatment quality of materials without changing the structure of the original calcining tube furnace.

[0014] As a further solution of the utility model: a support leg is arranged on one side of the bottom of the furnace frame, and an L-shaped support frame is arranged on the other side, and the height of the support leg is greater than the height of the support frame.

[0015] Since a support leg is provided on one side of the bottom of the furnace frame and an L-shaped support frame is provided on the other side, the height of the support leg is greater than the height of the support frame, so that the top of the furnace frame is tilted, and the furnace body is tilted along with the furnace frame, so that the material can slide freely due to its own gravity after entering from the feeding port, which is beneficial to the flow and distribution of materials during the heat treatment process. There is no need to continuously heat treat the material in a pushing boat manner, thereby improving the heating uniformity and heat treatment efficiency of the material.

[0016] As a further solution of the utility model: the angle between the top and the bottom of the furnace rack is 30°-90°.

[0017] Since the angle between the top and bottom of the furnace frame is 30°-90°, the furnace body maintains an inclined or vertical angle of 30°-90°. Since the furnace is full of materials, after the materials enter from the feeding port, the materials are stacked in sequence. When the rotary mechanical valve of the discharge valve is in a rotating state, the materials slowly slide freely through the furnace for heat treatment under their own gravity. There is no need to use a push boat, so that the materials are fully in contact with the heat source, and large quantities of materials can be continuously heat treated. The heating effect is more uniform, which further improves the production efficiency and heat treatment quality.

[0018] As a further solution of the utility model: a process gas pipe is arranged on the muffle furnace tube.

[0019] A process gas pipe is provided on the muffle furnace tube, and the process gas pipe delivers the process gas into the muffle furnace tube so that the process gas fills the entire furnace chamber, which can help the material to fully undergo heat treatment reaction in the furnace chamber and prevent external air from entering, effectively controlling the oxygen content of the material during the heat treatment process, maintaining the heat treatment environment in the furnace chamber, ensuring the stability of the heat treatment, and further improving the production efficiency and heat treatment quality of the material.

[0020] As a further solution of the utility model: the pipeline of the process gas pipe is provided with a gas flow meter.

[0021] Since the process gas pipe is equipped with a gas flow meter, the flow of the process gas can be monitored in real time through the gas flow meter, and the flow of the process gas can be adjusted according to the situation to achieve precise control of the gas flow during the heat treatment of the material and ensure the stability and controllability of the heat treatment conditions.

[0022] As a further solution of the utility model: a temperature detector is arranged on the top of the furnace.

[0023] Since a temperature detector is installed on the top of the furnace, the temperature changes inside the furnace can be monitored in real time, helping the operator to grasp the temperature conditions during the calcination process in time, so as to adjust the operating parameters and control the calcination process in time to ensure the stability and consistency of the heat treatment conditions.

[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0034] like Figure 1 The embodiment of the utility model shown is an inclined feeding calcining tube furnace, comprising: a furnace body 1, a furnace frame 101 is arranged at the bottom of the furnace body 1; the furnace body 1 includes a furnace chamber 102, and a muffle furnace tube 103 is arranged in the furnace chamber 102; one end of the furnace chamber 102 is connected to a feeding port 104, and the other end is connected to a furnace tail cooling pipe 105; one end of the furnace tail cooling pipe 105 is connected to a collection barrel 106, and a discharge valve 107 is arranged between the furnace tail cooling pipe 105 and the collection barrel 106, and the discharge valve 107 is provided with a rotating mechanical valve; the top of the furnace frame 101 is inclined, so that the furnace body 1 is inclined.

[0035] Specifically, by tilting the top of the furnace frame 101, the furnace body 1 is tilted along with the furnace frame 101. When the inclined feeding calcining tube furnace is in operation, the furnace chamber 102 is filled with materials, so that after the materials enter from the feeding port 104, the materials are stacked in sequence, and slowly pass through the furnace chamber 102 for heat treatment in a free sliding manner due to the tilted state of the furnace body 1 and the gravity of the materials themselves. The sliding speed of the materials is controlled by controlling the rotation speed of the rotary mechanical valve of the discharge valve 107, so that the materials are fully in contact with the heat source, and there is no need to use a boat to carry the materials, thereby saving space in the furnace chamber 102 and increasing the material loading in the furnace chamber 102, so that large quantities of materials can be continuously heat treated, and the heating effect is more uniform, thereby improving the quality of the heat treatment of the materials, and improving the production efficiency and heat treatment quality of the materials without changing the structure of the original calcining tube furnace.

[0036] like Figure 1 As shown, a support leg 108 is provided on one side of the bottom of the furnace frame 101 , and an L-shaped support frame 109 is provided on the other side. The height of the support leg 108 is greater than the height of the support frame 109 .

[0037] Specifically, since a support leg 108 is provided on one side of the bottom of the furnace frame 101 and an L-shaped support frame 109 is provided on the other side, the height of the support leg 108 is greater than the height of the support frame 109, so that the top of the furnace frame 101 is tilted, and the furnace body 1 keeps tilting along with the furnace frame 101, so that the material can slide freely due to its own gravity after entering from the feeding port 104, which is beneficial to the flow and distribution of the material during the heat treatment process. There is no need to continuously heat treat the material in a pushing boat manner, thereby improving the heating uniformity and heat treatment efficiency of the material.

[0038] Furthermore, the angle between the top and the bottom of the furnace frame 101 is 30°-90°.

[0039] Specifically, since the angle between the top and the bottom of the furnace frame 101 is 30°-90°, the furnace body 1 maintains an inclined or vertical angle of 30°-90°. Since the furnace 102 is full of materials, after the materials enter from the feeding port 104, the materials are stacked in sequence. When the rotary mechanical valve of the discharge valve 107 is in a rotating state, the materials slowly slide freely through the furnace 102 for heat treatment under their own gravity. There is no need to use a push boat, so that the materials are fully in contact with the heat source, and large quantities of materials can be continuously heat treated. The heating effect is more uniform, which further improves the production efficiency and the quality of heat treatment.

[0040] like Figure 1 As shown, a process gas pipe 110 is provided on the muffle furnace tube 103 .

[0041] Specifically, since the muffle furnace tube 103 is provided with a process gas pipe 110, the process gas pipe delivers the process gas into the muffle furnace tube so that the process gas fills the entire furnace 102, which can help the material to fully undergo a heat treatment reaction in the furnace 102, and can prevent external air from entering, effectively control the oxygen content of the material during the heat treatment process, maintain the heat treatment environment in the furnace 102, ensure the stability of the heat treatment, and further improve the production efficiency and heat treatment quality of the material.

[0042] Furthermore, a gas flow meter 111 is disposed on one side of the process gas pipe 110 .

[0043] Specifically, since a gas flow meter 111 is provided on one side of the process gas pipe 110, the flow of the process gas can be monitored in real time through the gas flow meter 111, and the flow of the process gas can be adjusted according to the situation to achieve precise control of the gas flow during the heat treatment of the material, thereby ensuring the stability and controllability of the heat treatment conditions.

[0044] like Figure 1 As shown, a temperature detector 112 is disposed on the top of the furnace 102 .

[0045] Specifically, since a temperature detector 112 is provided on the top of the furnace 102, the temperature changes inside the furnace 102 can be monitored in real time, helping the operator to timely grasp the temperature conditions during the calcination process, so as to timely adjust the operating parameters and control the calcination process to ensure the stability and consistency of the heat treatment conditions.
