Description

Technical Field

[0001] The utility model relates to the technical field of preheating devices, in particular to a melt filter preheating device. Background Art

[0002] Melt filter is a device used to filter molten materials. The filter materials include ceramics, ceramic fibers, metal fibers and steel meshes, etc. It is mainly composed of screens, screen frames, filter elements, inlet and outlet pipes and drive devices, etc. It is mainly used to remove impurities and unmelted particles in molten materials, such as particles, fibers, black spots, bubbles, etc.

[0003] The melt filter is preheated before use. Filter element preheating is a common step in certain industrial processes, especially in applications involving high-temperature melts or fluids. The main purpose of filter element preheating is to heat the filter element to a temperature close to or reaching the operating temperature before installing it in the filtration system to reduce the temperature difference between the filter element and the high-temperature melt, thereby preventing the filter element from being damaged by sudden heating, and also improving the filtration efficiency.

[0004] A Chinese patent discloses a melt filter preheating device with a publication number of CN212998793U, and the application date is 2020.03.31. The patented technology achieves the effect of rapid preheating of the melt filter by setting a group of heating devices on the outside of the mounting cylinder. However, the heating device of the above device is set on the outside of the mounting cylinder, and then the heat is transferred to the melt filter inside the mounting cylinder by heat transfer. This transfer method cannot directly transfer the surface of the melt filter, so the heating speed is relatively slow and the heating effect is relatively poor, which in turn affects the efficiency of preheating the melt filter. Therefore, the inventor provides a melt filter preheating device to solve the problems raised in the above background technology. Summary of the invention

[0005] The utility model aims to provide a melt filter preheating device to achieve the effect of rapid preheating of the melt filter.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A melt filter preheating device comprises a preheating cylinder, the bottom of which is fixedly connected with four supporting feet, and the top of which is installed with a sealing cover; the inner bottom side of the preheating cylinder is fixedly connected with a supporting seat, and the top of the supporting seat is placed with a melt filter body, characterized in that a heating mechanism for preheating the melt filter body is arranged inside the preheating cylinder, and the heating mechanism comprises a movable groove provided inside the preheating cylinder, a group of sliding grooves are provided inside the movable groove, a movable sliding rod is slidably connected inside the sliding groove, an electric heating plate is fixedly connected to the inner side of the sliding rod, and the surface of the electric heating plate is in the shape of an arc.

[0008] As a further solution of the utility model: a through groove is provided at the bottom of the support seat, and a discharge pipe is fixedly connected to the bottom of the preheating cylinder, and the discharge pipe corresponds to the position of the through groove.

[0009] As a further solution of the utility model: the cross section of the movable groove is adapted to the size of the side surface of the sliding rod.

Since the electric heating plates are heated by direct contact and the electric heating plates usually use a resistance heating wire as a heating element, this element can directly convert electrical energy into thermal energy with high conversion efficiency, so the heating speed is fast, so that the temperature of the melt filter can be quickly reached, thereby achieving a rapid preheating effect.

[0016] In addition, the melt filter preheating device is provided with a group of rollers on the top of the support box.

DETAILED DESCRIPTION

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application 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 present application and are not used to limit the present application.

[0025] like Figure 1 , 2 As shown, a melt filter preheating device comprises a preheating cylinder 10, four supporting feet 11 are fixedly connected to the bottom of the preheating cylinder 10, and a sealing cover 12 is installed on the top of the preheating cylinder 10; a support seat 13 is fixedly connected to the inner bottom side of the preheating cylinder 10, and a melt filter body 40 is placed on the top of the support seat 13, and the support seat 13 is used to support and stabilize the melt filter body 40. A heating mechanism 20 for preheating the melt filter body 40 is arranged inside the preheating cylinder 10.

[0026] Preferably, a through groove (not shown in the figure) is opened at the bottom of the support seat 13, and a discharge pipe 14 is fixedly connected to the bottom of the preheating cylinder 10, and the discharge pipe 14 corresponds to the position of the through groove. When in use, the sealing cover 12 is lifted by a crane, and then the melt filter body 40 is lifted and placed into the interior of the preheating cylinder 10 until the melt filter body 40 is placed on the support seat 13. During the heating filtration, the residual solution in the melt filter body 40 will be discharged through the through groove and the discharge pipe 14. After the melt filter body 40 is preheated, the melt filter body 40 is taken out in the same way.

[0027] refer to Figure 2-6 The heating mechanism 20 includes a movable groove 203 opened inside the preheating cylinder 10, a group of sliding grooves 201 are opened inside the movable groove 203, a movable sliding rod 202 is slidably connected inside the sliding groove 201, and an electric heating plate 212 is fixedly connected to the inner side of the sliding rod 202. The surface of a group of electric heating plates 212 is arc-shaped. When four electric heating plates 212 are abutted against each other, they are cylindrically attached to the outer surface of the melt filter body 40.

[0028] Preferably, the cross section of the movable groove 203 is adapted to the size of the side surface of the sliding rod 202, so as to achieve a guiding effect when the sliding rod 202 moves.

[0029] Specifically, a group of supporting mechanisms 30 are arranged on the side of the movable groove 203 away from the electric heating plate 212, and a ring 204 is rollingly connected to the top of the supporting mechanism 30, and a group of guide grooves 206 are opened on the top of the ring 204; a rolling rod 205 is rotatably connected to the top of the sliding rod 202, and the rolling rod 205 extends downward and is located inside the guide groove 206, and the rolling rod 205 is rollingly connected to the guide groove 206. A driving groove 207 is opened on the left side of the movable groove 203, and a group of teeth 208 are fixedly connected to the left surface of the ring 204; a supporting plate 211 is fixedly connected to the left side of the preheating cylinder 10, and a motor 210 is fixedly connected to the top of the supporting plate 211, and a gear 209 is fixedly connected to the output end of the motor 210, and the gear 209 is meshed with the teeth 208.

[0030] Preferably, the guide groove 206 is designed to be an arc-shaped design that gradually approaches the outside in a clockwise direction; when in use, the motor 210 is started by an external power supply, and the output end of the motor 210 drives the gear 209 to rotate clockwise, thereby driving the teeth 208 and the ring 204 to rotate clockwise, and the rotating ring 204 allows the rolling rod 205 to roll along the inside of the guide groove 206. Since the guide groove 206 is designed to be an arc-shaped design that gradually approaches the outside in a clockwise direction, it will drive the rolling rod 205 to be gradually pushed inward, thereby driving the sliding rod 202 to rotate clockwise. The electric heating plate 212 moves inwardly to make a group of electric heating plates 212 fit the surface of the melt filter body 40, and then the electric heating plate 212 is started by an external power supply to preheat the melt filter body 40. Since the electric heating plate 212 is heated by direct contact and the electric heating plate usually uses a resistance heating wire as a heating element, this element can directly convert electrical energy into thermal energy with high conversion efficiency, so the heating speed is fast, so that the temperature of the melt filter body 40 can be quickly increased, thereby achieving a rapid preheating effect. Similarly, the reversal of the output end of the motor 210 can make the four electric heating plates 212 move in opposite directions, so as to facilitate the removal of the melt filter body 40.

[0031] refer to Figure 6 The support mechanism 30 includes a support box 301 fixed on the surface of the movable groove 203. A group of rollers 302 are arranged on the top of the support box 301. The rollers 302 are in contact with the bottom surface of the ring 204, thereby achieving the effect of supporting the ring 204, and when the ring 204 rotates, the rollers 302 are driven to roll, thereby reducing the friction force when the ring 204 rotates.

[0032] The working principle of the utility model is: the motor 210 is started by an external power supply, and the output end of the motor 210 drives the gear 209 to rotate clockwise, thereby driving the teeth 208 and the ring 204 to rotate clockwise, and the rotating ring 204 allows the rolling rod 205 to roll along the inside of the guide groove 206. Since the guide groove 206 is an arc-shaped design that gradually approaches the outside in the clockwise direction, it will drive the rolling rod 205 to gradually push inward, thereby driving the sliding rod 202 to move inward, so that a group of electric heating plates 212 are attached to the surface of the melt filter body 40, and then the electric heating plates 212 are started by an external power supply, so that the electric heating plates 212 preheat the melt filter body 40. Since the electric heating plates 212 are heated by direct contact and the electric heating plates usually use a resistance heating wire as a heating element, this element can directly convert electrical energy into thermal energy with high conversion efficiency, so the heating speed is fast, so that the temperature of the melt filter body 40 can be quickly increased, thereby achieving a rapid preheating effect.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
