Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, specifically to a temperature-controlled mixing unit for heating equipment. Background Technology

[0002] With the development of urban construction, centralized heating has become a common method of urban heating. A mixing unit is an energy-saving and efficient hot water heating device. Controlled by a controller, hot water from the heat source enters through the primary side network supply pipe and is supplied to users through the secondary side network supply pipe. After use, the cold water is recycled through the secondary side network return pipe. A portion flows through a one-way valve into the return pipe, mixes with the primary side network supply pipe, and is reused in the secondary side network supply pipe; the other portion flows back to the heat source from the primary side network return pipe for reheating. Therefore, a Chinese utility model patent (publication number: CN221648575U) has been granted for a temperature-controlled mixing unit for heating equipment. This mixing unit filters scale through a filter screen and collects scale through a collection pipe. The collection pipe can be removed for cleaning by rotating two connecting rings, thus preventing scale from entering the circulation pump and affecting its normal operation.

[0003] However, the filter screen used to filter scale in this mixing unit is directly installed inside the slot. After long-term use, when a lot of scale accumulates on the surface of the filter screen and inside the filter holes, it is troublesome, time-consuming and laborious to disassemble and clean the filter screen. The disassembly and assembly of the filter screen is difficult and can easily affect the cleaning efficiency of the filter screen. Therefore, a temperature-controlled mixing unit for heating equipment is proposed to address the above situation. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a temperature-controlled mixing unit for heating equipment, including a circulating pump 1, a filter box 2, a filter screen 3, and a locking component 4. The input end of the circulating pump 1 is connected to a side plate of the filter box 2, and an inlet pipe 101 is connected to the input end of the circulating pump 1. A second conduit 206 is provided on the filter box 2, and one end of the second conduit 206 is connected to the inlet pipe 101. An outlet pipe 102 is connected to the output end of the circulating pump 1, and a mixing cylinder 8 is provided at one end of the outlet pipe 102. A circulation pipe 9 is connected to one end of the mixing cylinder 8. A first conduit 205 is provided on the side plate of the filter box 2 away from the second conduit 206, and one end of the first conduit 205 is connected to the side of the circulation pipe 9, which can form a complete water circulation to ensure heating.

[0024] The filter box 2 has two sliding grooves 201, and the sliding grooves 201 have a receiving groove 202, and the receiving groove 202 has a through hole 203.

[0025] The filter screen 3 is equipped with two sliders 301, which cooperate with the slide groove 201. The sliders 301 have arc-shaped slots 302. The top of the filter box 2 is equipped with a top plate 204, which has a rectangular through groove 2041. The top of the filter screen 3 is equipped with a sealing plate 303, which cooperates with the rectangular through groove 2041 to facilitate the sliding of the filter screen 3 out of the filter box 2. The sealing plate 303 has three sealing strips on both sides to improve the sealing of the filter box 2. The sealing plate 303 is equipped with a lifting handle to facilitate the pulling of the filter screen 3. The bottom of the filter screen 3 is equipped with a positioning block. The filter box 2 is equipped with a placement platform 5, which has a positioning groove. The positioning block cooperates with the positioning groove to position the filter screen 3 and ensure accurate installation of the filter screen 3.

[0026] Two locking components 4 are provided. Each locking component 4 includes a movable latch 401, which engages with an arc-shaped groove 302. The movable latch 401 is rotatably installed within the receiving groove 202. A bearing is embedded at the bottom of the movable latch 401, and a shaft is fitted to the inner ring of the bearing. Both ends of the shaft are connected to the bottom inner wall of the receiving groove 202, allowing the movable latch 401 to rotate within the receiving groove 202. This facilitates the engagement and disengagement of the movable latch 401 with the arc-shaped groove 302. A square groove 4011 is provided on the movable latch 401, within which a pull rod 402 is rotatably installed. Two circular grooves are provided, and bearings are fitted into the grooves. One end of the pull rod 402 is provided with a shaft, and both ends of the shaft are fitted with the inner rings of the two bearings. This allows the pull rod 402 to rotate easily with the movable buckle 401, ensuring the horizontal displacement of the pull rod 402 within the through hole 203. A spring 403 is fitted on the outer surface of the pull rod 402, and one end of the pull rod 402 is fitted with the through hole 203. The end of the pull rod 402 away from the movable buckle 401 passes through the through hole 203 to the outside of the filter box 2. A pull ring is provided on the end of the pull rod 402 away from the movable buckle 401, which allows the movable buckle 401 to be pulled easily.

[0027] When the filter screen 3 needs to be disassembled and cleaned after filtering the circulating water for a long time, pull the pull ring on the pull rod 402 of the two locking parts 4 at the same time. This causes the pull rod 402 to slide in the through hole 203 and compress the spring 403. This causes one end of the pull rod 402 to rotate in the square groove 4011 and pull the movable buckle 401 to rotate in the receiving groove 202. By rotating the movable buckle 401 into the receiving groove 202, the movable buckle 401 is disengaged from the arc-shaped groove 302, thereby releasing the restriction on the two sliders 301. Then, the filter screen 3 is pulled upward by the sealing plate 303, so that the filter screen 3 slides out of the filter box 2. Similarly, the above operation is repeated in the opposite way to install the filter screen 3 into the filter box 2.

[0028] An arc-shaped guide block 6 is provided on one side of the placement platform 5. The bottom of the arc-shaped guide block 6 is connected to the bottom inner wall of the filter box 2. A discharge pipe 7 is embedded in the bottom of the filter box 2. The interior of the discharge pipe 7 is connected to the interior of the filter box 2. A valve is provided on the discharge pipe 7.

[0029] After the scale in the circulating water is filtered by the filter screen 3, the filtered scale settles in the area where the arc-shaped guide block 6 is located in the filter box 2. The scale slides through the arc-shaped surface of the arc-shaped guide block 6 into the position of the top of the discharge pipe 7 below it. Then, the valve set on the discharge pipe 7 is opened, so that the scale is discharged from the filter box 2 through the discharge pipe 7, thereby removing the scale accumulated in the filter box 2.
